• Actionized Sequel: Vampiresaur is a slow-paced survival horror drama with minimal action, a Slow-Paced Beginning allowing audiences to ease into the adventure, a serious exercise in Nothing Is Scarier that slowly but surely reveals the dark secrets surrounding Dylan's changing world, minimal screen-time for Rexula that's completely concentrated into the final third of the film's runtime, no weapons, Marines, or non-vampire dinosaurs involved in the central conflict, only one vampire dinosaur seen throughout the film, prolonged "suspence" sequences leading up to Rexula's next attack, and extended "pauses" between Rexula's attacks. The sequels, however, are faster-paced science-fiction/action/war films with more action, shorter opening sequences allowing the central conflict to begin faster, less emphasis on Nothing Is Scarier, more screen-time for the vampire dinosaurs beginning far sooner into their runtimes, countless energy weapons, Marines, and non-vampire dinosaurs involved in the central conflict, even though Vampiresaur Extinction only has one Marine and no non-vampire dinosaurs in it, endless swarms of vampire dinosaurs seen throughout the films, even though Vampiresaur Extinction only has one vampire dinosaur in it like Vampiresaur, shorter/no "suspence" sequences leading up to the vampire dinosaurs' next attack, and shorter "pauses" between the vampire dinosaurs' attacks.
• The Ageless: Though the vampire dinosaurs can't die of old age, they can still be killed through other means.
• Antagonist Title: The franchise monikor is a portmanteau referring to its main antagonists: vampire dinosaurs.
• Artistic License – Biology: The eponymous villains are hematophagous dinosaurs that can sometimes be Kaiju-sized and infect their victims with their virus after they've already been killed; however, in real life, hematophagous creatures are usually small due to blood providing less nutrition than meat and bones, and viruses are never capable of infecting already dead organisms.
• Artistic License – Military: The Marines routinely recruit grade-schoolers into their ranks and wear uniforms outfitted with metallic-plating around their torsos (making it impossible for the vampire dinosaurs to bite into their torsos); however, real life Marines never recruit anyone under 16 into their ranks or wear uniforms outfitted with armor-plating of any sort.
• Artistic License – Paleontology: Many of the dinosaurs' designs feature scientific inaccuracies such as featherless/pycnofiberless bodies, exaggerated sizes, hollow grooves in their teeth/beaks for sucking one's blood through, hidden holes sucked blood enters the villains' circulatory systems through inside their teeth/beaks, and palette swaps of designs pulled from other dinosaur media; however, the aforementioned deviations from paleontological accuracy are present to help the villains be what they're meant to be, make the dinosaurs look cooler, and add to the franchise's overall horror factor.
• Big Bad: The vampire dinosaurs are the main villains causing the problems the heroes must resolve.
• Bittersweet Ending: Though many heartaches befall the heroes at the end of each film, each ending still also leaves them with a chance to make things better for themselves.
• Black Eyes of Evil: All male/asexual vampire dinosaurs sport mainly black eyes and glowing red pupils.
• Bloodless Carnage: Under most circumstances, no blood is shown as a result of the vampire dinosaurs sucking it all into themselves.
• Blue Is Heroic: Blue is one of the heroes' main color motifs.
• Book Ends: Every film begins with Dylan waking up (and ends with Dylan going to sleep).
• Call-Back: Each sequel features references to its canonical predecessors that are relevent to its plot.
• Cataclysm Climax: Each film's climactic sequence features either a volcano erupting or a nuclear bomb detonating (if not both).
• Child Soldier: Though he doesn't become one until Vampiresaurs, Dylan is forced to develop a "military man's mentality" at 8 years old when Rexula kills his entire immediate family as he finds a way to eliminate Rexula and save the world from him. When Dylan (actually) joins the Marines, he's only 9 years old, and a number of other grade-schoolers also join him and the other Marines on their horrifying adventure.
• Clone by Conversion: One of the eponymous villains' main methods of reproduction involves using their virus to transform other entities into more of themselves.
• Color-Coded for Your Convenience: The vampire dinosaurs are always Red and Black and Evil All Over (whereas the non-vampire dinosaurs have all sorts of different colors on them) so you can easily tell the two groups apart.
• Color Motif: Each film has its own "theme color" used for many inanimate objects seen throughout it and its camera color filters.
• Conservation of Ninjutsu: In Vampiresaur and Vampiresaur Extinction, Dylan and company only fight one vampire dinosaur, but said lone vampire dinosaur quickly prooves to be nearly unstoppable as he slaughters the humans right and left until only one of them is left alive, at which point said lone human does something extremely unconventional to kill the attacking vampire dinosaur. In Vampiresaurs, Vampiresaurs: The South American Siege, and Vampiresaurs: The Asian Infestation, Dylan and company manage to slaughter enormous hives of vampire dinosaurs led by (Kaiju)-sized queens and empresses, but this phenomenon is mainly justified by the absence of weapons, Marines, and non-vampire dinosaurs in Vampiresaur (along with dark and enclosed spaces for Rexula to hide and ambush his targets more easily in), the big bad's Nigh-Invulnerability in Vampiresaur Extinction, and the heavy presence of energy weapons, Marines, and non-vampire dinosaurs in Vampiresaurs, Vampiresaurs: The South American Siege, and Vampiresaurs: The Asian Infestation.
• Contrasting Sequel Antagonist: Due to the vampire dinosaurs' genetic upgrades, each film's big bad differs from the others in multiple ways.
• Contrasting Sequel Setting: Each film's setting is radically different from the other films' settings.
• Dark Is Evil: Male/asexual vampire dinosaurs are partially characterized by their mainly black skin and eyes.
• Darkness Equals Death: Vampire dinosaur attacks often take place when people venture into dark areas (such as caves, empty magma tubes, sewers, and subway tunnels).
• David Versus Goliath: In each installment, Dylan battles vampire dinosaurs far bigger and stronger than himself.
• Death of a Child: The vampire dinosaurs slaughter and infect children right and left whenever they get near them.
• Enemy-Detecting Radar: The humans regularly use motion-trackers to figure out where the vampire dinosaurs are hiding from them.
• Evil Evolves: Overtime, the vampire dinosaurs are biologically upgraded to counter the heroes' advancements.
• Evil Is Bigger: The (named) vampire dinosaurs are typically far larger than any of their adversaries (human or dinosaur).
• Explosive Breeder: The vampire dinosaurs are outfitted with many methods of reproduction: eggs, viral infections, and new specimens growing and developing inside infected entities, allowing them to increase their numbers at alarming rates.
• Extremely Short Timespan: Each film takes place over just a few days or hours.
• Family of Choice: After Rexula kills Dylan's immediate family, Dylan flees to Julie's apartment because he knows she'll be willing to take care of him, and when Dylan joins the Marines, his old classmates, countless Marines, and non-vampire dinosaurs become his "chosen family." When Dylan boards the International Space Station, the station's crew (briefly) becomes his new "chosen family" prior to being slaughtered and infected by Dracuviscerator.
• Faster Than They Look: Though many of the villains are massive dinosaurs with tons of musculature helping them overpower their adversaries, they can still run at frighteningly fast speeds.
• Forced Transformation: Once someone is infected with the vampire virus, said vampire virus forcefully transforms him/her into a new vampire dinosaur, and its effects can't be reversed under any circumstances.
• Foreshadowing: Countless future events are vaguely hinted at via character dialogue (especially in the franchise's first installment).
• Genetic Memory: Dead villains' memories are constantly implanted into subsequent villains' brains to grant them combat experience and animosity towards their adversaries they'd never have otherwise.
• Glowing Eyes of Doom: The male/asexual vampire dinosaurs sport glowing red pupils, and the female/hermaphroditic vampire dinosaurs sport glowing red eyes with "normal" black pupils.
• Good Colors, Evil Colors: The vampire dinosaurs are always Red and Black and Evil All Over to compliment their nature as the eponymous villains, and the Marines and non-vampire dinosaurs often visually boast blue, green, purple, yellow, white, orange, brown, and other "positive" colors to compliment their nature as the heroes.
• Go-to-Sleep Ending: Each film ends with Dylan going to sleep.
• Greater-Scope Villain: Though Islamic Terrorists are responsible for the vampire dinosaurs' existence, they don't (usually) have any direct influence on the franchise's plot.
• Healing Factor: The vampire dinosaurs can rapidly regenerate whenever they're injured.
• Hellish Pupils: The male/asexual vampire dinosaurs' pupils are best known for their glowing red hue.
• Hero Killer: The vampire dinosaurs kill and infect every single one of the franchise's (human) heroes (named or unnamed) aside from Dylan.
• Horror Hunger: The vampire dinosaurs' hematophagous nature makes them relentlessly pursue and suck blood from other entities, and whenever there's no blood to go around, they shut down their bodily functions to conserve energy.
• Implacable Man: The vampire dinosaurs are super persistent predators equipped with all sorts of biological upgrades that make it so they can't be pinned down for very long (no matter hard you fight back against them).
• Improbable Infant Survival: Despite only being an 8-12-year-old minor when the franchise takes place, Dylan lives to see its ending, even though no other humans do.
• Jurassic Farce: The franchise is centered around bringing the dinosaurs back from extinction, allowing them to wreak havoc on the modern world.
• Kid Hero: The franchise begins when Dylan is only 8 years old and ends when Dylan is 12 years old; several (named) individuals close to Dylan's age also join him on his horrifying adventure.
• Kudzu Plot: The franchise features many plot threads that eventually come together to create a large-scale and complex (yet also easily understandable) narrative surrounding a young boy and the changing universe around him (especially during the franchise's first installment).
• Lightning Bruiser: The vampire dinosaurs are incredibly powerful and can run and fly extremely fast.
• Long Hair Is Feminine: Female humans have longer hair than male humans.
• Mature Work, Child Protagonists: Though this is a sci-fi/horror franchise with thematic ties to the Alien, Godzilla, Jurassic Park, and Star Wars franchises, it features a young boy as its main protagonist.
• May the Farce Be with You: Though Star Wars references are less prevelant than Alien and Jurassic Park references, they still constantly crop up in the form of Good Colors, Evil Colors, energy weapons, and young people rising up to tackle villains who are way older and stronger than themselves.
• Meaningful Name: Each main antagonistic dinosaur's name is a portmanteau reflecting his/her most notable biological characteristics.
• Monster Progenitor: Every film's central conflict begins with a vampire dinosaur being created and sent on a mission to spawn countless more vampire dinosaurs via laying eggs, infecting other entities, and making new vampire dinosaurs grow and develop inside them; however, their success widely varies depending on subsequent circumstances.
• Monster Threat Expiration: As the franchise progresses, the average (unnamed) vampire dinosaur's individual threat level drastically diminishes as a result of the heroes' combat capabilities continuously being upgraded.
• Names to Run Away from Really Fast: Every main antagonistic dinosaur's name is designed to instill fear into the franchise's human characters and out-of-universe audiences alike, and many real life carnivores with frightening names (such as Tyrannosaurus rex, Tarbosaurus, Teratophoneus, Deinonychus, Velociraptor, Megaraptor, Suchomimus, Giganotosaurus, and Tyrannotitan) routinely appear throughout the franchise.
• Never Recycle Your Schemes: Every time a given scheme on the villains' part fails, the villains always devise entirely new schemes afterwards.
• New Powers as the Plot Demands: As the Marines and vampire dinosaurs' arms race progresses, they attain many new powers and abilities.
• Nightmare Sequence: Prior to confronting the eponymous villains, Dylan always has nightmares about them attacking him.
• Not Quite Dead: From time-to-time, the vampire dinosaurs and other villains (seemingly) die upon being hit with especially powerful attacks, only for them to come back and bite the heroes again later.
• Obviously Evil: The vampire dinosaurs' abnormal-looking eyes and foreboding color schemes are designed to let you know they're evil just by having you look at them.
• Oddball in the Series: Every installment has its own set of thematic elements that separates it from the other installments.
• Omnicidal Maniac: The vampire dinosaurs and their creators are obsessed with eliminating all life in the universe in service to Allah.
• The Oner: Many pivotal moments occur as long-lasting shots filmed from Dylan's POV, and at times, they can be over 5 minutes long.
• Our Vampires Are Different: Exaggerated. Not only are this franchise's vampires virus-infected and hematophagous dinosaurs instead of undead and hematophagous humans, they also use all their teeth/beaks to suck blood from their adversaries. They're still vulnerable to sunlight (at first) until genetic upgrades allow them to attack during broad daylight, and they mainly reproduce via laying eggs, infecting their adversaires via biting into them and having airborne vampire virus spores enter suitable hosts from either their own bodies or vampire virus spore capsules they regurgitate onto the ground upon taking in sufficient sustenance to transform their adversaries into more of themselves, and making new infant vampire dinosaurs grow and develop inside their adversaries' bodies upon infecting them with their virus. The vampire dinosaurs also often find themselves under the leadership of Kaiju-sized and genetically modified hybrid vampire monarchs resembling not zillas, and their flying forms are pterosaurs instead of vampire bats. In some instances, they can even be genetically modified hybrids between different dinosaur species, and they're instinctively programmed not to attack each other under any circumstances.
• Parental Substitute: Following Dylan's real mother's death, Julie, Dylan's only living cousin, assumes the role of Dylan's adoptive mother, and when the vampire dinosaur threat reemerges in Los Angeles, United States Marine Corporal Boris Hicks becomes Dylan's adoptive father of sorts. Upon having Dylan board the International Space Station, Neil Brice, one of the astronauts aboard the station, also becomes another adoptive father figure for Dylan.
• Portmanteau: The franchise monikor is a mash-up of "vampire" and "dinosaur", and the main villains' names are always mash-ups of either "Dracula" or "vampire" and something else.
• Post-Climax Confrontation: Near the end of each film, right as it seems like Dylan has escaped further conflict, at least one still-surviving antagonist returns to confront Dylan one final time, only for Dylan to slaughter said final antagonist and conclude his conflict with him/her/them until the next installment.
• P.O.V. Cam: Dylan's nightmare sequences and other important moments are viewed through his eyes.
• Predators Are Mean: Zigzagged. The meat-eating dinosaurs on the villains' side are always cruel and sadistic towards their adversaries, but the meat-eating dinosaurs on the heroes' side are just as friendly and caring as their herbivorous colleagues.
• Quirky Work: The franchise follows a young boy battling virus-infected and hematophagous dinosaurs.
• Real Women Don't Wear Dresses: Not only do this franchise's female human characters literally never wear any dresses, they're also just as adept at fighting the vampire dinosaurs as the male humans.
• Recurring Element: Extensive shots viewed from Dylan's POV, walkie-talkie conversations, the eponymous villains using their virus to transform their adversaries into more of themselves, each main villain being stronger and deadlier than the previous, the lead hero having nightmares about his main adversaries before meeting them in reality, at least one more antagonist confronting Dylan following each installment's climax, the vampire dinosaurs hanging out in dark subterranean areas, and Dylan going to sleep at the end of each installment are just a few of the features regularly cropping up throughout the franchise.
• Red and Black and Evil All Over: The eponymous villains always have red and black skin and eyes.
• Red Eyes, Take Warning: The vampire dinosaurs' eyes always glow red, so if you see any glowing red lights in the distance, you know they're coming for you.
• Red Is Violent: The vampire dinosaurs have partially red skin and eyes, and their normal behavior is extreme violence towards their adversaries.
• Reference Overdosed: The franchise contains countless Shout Outs to preexisting media.
• Rock Beats Laser: Routinely zigzagged with man versus vampire dinosaur battles. Whenever unarmed men battle the franchise's eponymous villains, the extremely biologically advanced vampire dinosaurs invert this trope by rapidly defeating their biologically obsolete adversaries, but whenever heavily armed and trained men battle the vampire dinosaurs, the men play this trope straight by using blaster-bolts, lasers, missiles, grenades, and nukes to blast the vampire dinosaurs into oblivion.
• Rule of Cool: Though the franchise's main events are scientifically impossible in real life, hidden scientific loopholes are exploited to allow them to happen anyway.
• Rule of Drama: Every film's central conflict's specific details and parameters are set up in such a way that it's fair to both sides of it.
• Rule of Scary: The presence of vampire dinosaurs in the franchise is solely for the purposes of creating the new scariest film franchise ever.
• Saved for the Sequel: Plot points set up in one installment often aren't further expanded upon until one of the later installments.
• Sequel Escalation: In Vampiresaur, just one male vampire Tyrannosaurus rex attacks and kills an unarmed family of five except for one inside Mauna Loa. In Vampiresaurs, countless heavily-armed Marines and non-vampire dinosaurs belonging to every North American herbivorous species exterminate a vampire dinosaur hive featuring every North American theropod and pterosaur species and its massive genetically modified hybrid queen underneath Los Angeles. In Vampiresaurs: The South American Siege, every North American dinosaur species and surviving Angelino Marine joins forces with Miami and South American Marines and every South American dinosaur species against multiple vampire dinosaur hives and outposts containing every European, South American, and African theropod and pterosaur species (along with bigger, stronger, and more biologically advanced vampire dinosaur queens, second-in-command hybrids, and random vampire hybrids between African dinosaur species) scattered across South America. In Vampiresaurs: The Asian Infestation, every surviving Marine from the previous film and every North American dinosaur species joins forces with Asian Marines and every Asian dinosaur species against vampire versions of every theropod and pterosaur species from the world over, vampire versions of aquatic dinosaur species, the vampire dinosaurs' Islamic Terrorist creators, a new second-in-command hybrid, countless random vampire hybrids between various dinosaur species, and a vampire dinosaur empress scattered across Asia, and in Vampiresaur Extinction, the previous four films' sole survivor joins forces with the International Space Station's astronaut crew against one last-surviving Islamic Terrorist and one last genetically modified hybrid asexual vampire dinosaur across Earth, the aforementioned space station, Earth's moon, and Mars.
• Sequel Hook: Each film's ending features elements foreshadowing the next film's plot.
• Serial Escalation: The (named) vampire dinosaurs' body sizes and films' geographical settings enlarge with each installment.
• Shapeshifter Default Form: Every named vampire dinosaur's "main" form is a ground-bound theropod of some sort.
• Shout-Out: Has its own folder.
• Sorting Algorithm of Evil: Genetic upgrades applied to the eponymous villains overtime makes every (named) vampire dinosaur much more formidable than the previous.
• Stealthy Colossus: Despite their massive size, the vampire dinosaurs can sneak up on people in dark areas.
• Super-Persistent Predator: The vampire dinosaurs relentlessly pursue their adversaries whenever they're active because they need copious blood to fuel their bodies.
• Super-Toughness: The vampire dinosaurs have far greater bodily durability than their real life counterparts.
• Suspiciously Stealthy Predator: When in dark areas, the vampire dinosaurs' dark bodies make them nearly impossible to spot without motion-trackers.
• Technically-Living Vampire: The vampire dinosaurs are vampires because they're infected with a manmade virus that makes them hematophagous (meaning they're not undead like traditional vampires).
• Technicolor Fire: Every time fire shows up, it always sports a different color from (most) real life fire, and depending on the installment, it can more specifically be either red, blue, orange, green, or purple in color.
• Terror-dactyl: The (named) vampire dinosaurs assume monstrous pterosaur forms whenever they need to either get somewhere in a hurry or counter their adversaries' defensive strategies more easily.
• Tertiary Sexual Characteristics: Female humans can be distinguished from male humans via the following differences from said male humans: lipstick, nail polish, longer hair, less-revealing swimwear, wearing actual sleepwear when going to bed, and their habit of going barefoot whenever possible.
• There Is No Kill Like Overkill: The heroes do whatever it takes to kill their adversaries (even if it means melting and vaporizing every last one of their cells via volcanic eruptions and nuclear detonations).
• Time Skip: One year passes between each film.
• Took a Level in Badass: As the franchise progresses, Dylan goes from an "everyman" to the universe's ultimate hero via his conflict with the eponymous villains.
• To Serve Man: The vampire dinosaurs constantly target human blood because they know humans are way easier to defeat than non-vampire dinosaurs.
• Toxic Dinosaur: The vampire dinosaurs constantly use their virus to infect and transform other organisms into more of themselves.
• Ultimate Life Form: Every (named) vampire dinosaur is a failed attempt at creating such because of initially hidden weaknesses later rectified in one of the sequels up until Dracuviscerator is revealed to have an absolute-zero temperature weakness near the end of Vampiresaur Extinction.
• Villain-Based Franchise: The franchise is completely centered around its eponymous villains and their doings plus creators, so when they're defeated for good, the franchise dies with them.
• Villain Decay: Rexula from Vampiresaur has the highest kill-count of any (normal-sized) vampire dinosaur until Dracuviscerator comes along in Vampiresaur Extinction (meaning normal-sized vampire dinosaurs have their individual threat level drastically reduced by the existence of energy weapons and non-vampire dinosaurs following Rexula's death) until Dracuviscerator's genetic upgrades invert that trend.
• Villain Killer: Dylan is mainly the one to slaughter the vampire dinosaurs right and left until none of them are left alive.
• Villainous Legacy: Every time one villain dies, his/her presence is still felt in later installments due to his/her genetic memories being implanted into subsequent villains' brains.
• Viral Transformation: Vampire dinosaur transformations occur whenever people get infected with the vampire virus.
• The Virus: The vampire dinosaurs harbor a manmade virus rendering them hematophagous in their bodies at all times, and they can infect whatever and whoever they want with it to transform their adversaries into more of themselves (as long as their targets aren't vaccinated against their virus).
• Voluntary Shapeshifting: The vampire dinosaurs can switch back-and-forth between their terrestrial and flying forms whenever they want.
• Whole-Plot Reference: This franchise is the Alien franchise but with vampire dinosaurs instead of Xenomorphs, (mostly) eartly locations and Marines instead of extraterrestial locations and space marines, a young boy protagonist instead of a woman protagonist, and energy weapons instead of kinetic weapons.
• Would Hurt a Child: Whenever human children and vampire dinosaurs meet, the latter group constantly attempts to bite into, suck blood from, infect, and assimilate the former group.
• Xenomorph Xerox: The vampire dinosaurs have many similarities to the Alien franchise's Xenomorphs: largely dark bodies, hive caste systems, multiple methods of reproduction, the ability to make anyplace they visit completely uninhabitable in no time flat, thematic connetions to the aforementioned franchise's scrapped concepts, and genetic programming that prevents them from attacking each other under any circumstances.
• You Can't Go Home Again: As a result of his entire immediate family dying in Vampiresaur, Los Angeles getting nuked in Vampiresaurs, and non-vampire dinosaurs reclaiming the earth in Vampiresaurs: The Asian Infestation, Dylan is unable to return to his old home at the end of Vampiresaur Extinction.

• The protagonist's first name references Craig Dylan from Jurassic: The Hunted. The middle name references King Arthur, and the last name references McCarthyism.
• The male vampire dinosaurs' eye design resembles those of Sonic.exe and the new-model Xenomorphs from the first draft of William Gibson's unused Alien³ script.
• The Islamic Terrorists' role in the franchise mirrors those of the Pacific Rim Precursors, the Terminator franchise's Skynet, and the Alien franchise's Weyland-Yutani Corporation.
• Each film's setting has its own set of thematic connetions to the Alien franchise's settings, and each big bad also has his/her own set of thematic connetions to the Alien franchise's big bads.
• Like Godzilla, every big bad is a manmade dinosaur that goes on an omnicidal rampage against humanity, and it's not uncommon for them to have dorsal plates and spikes as well.
• The franchise's military personnel are Marines like the United States Colonial Marines.
• The heroes' weapons are energy weapons, and the protagonist goes from an "everyman" to the universe's greatest ever hero in just a few years like in Star Wars.
• Like the Jurassic Park/World franchise's dinosaurs, this franchise's dinosaurs are always either clones, genetically modified hybrids, or descendants of the other two groups, don't have any feathers or pycnofibers, and always attack their targets via picking them up in their mouths, lifting them off the ground, biting into various parts of them at once while hunting in packs, biting into the heads and necks of similarly-sized targets, always breaking out of their containment areas, and opening doors.

• The franchise was originally conceived as a six-part arc, but it was later shortened to four parts due to it being too long. The franchise was also later extended back to five parts due to it then being too short.
• After the second installment, the organic vampire dinosaurs were originally meant to be replaced with cybernetically enhanced and robotic vampire dinosaurs, but they were scrapped due to the concept being too far fetched, even by this franchise's standards.
• The International Space Station was originally not involved in the franchise's plot, but it was later added to it to make sure Dylan is humanity's sole survivor by the end of it.
• The vampire virus originally couldn't do anything more than make the eponymous villains be what they are, and its background information was originally not-so fleshed out. New information about it and powers for it were later added to enhance its Nightmare Fuel factor.
• The time gap between the franchise's beginning and end was originally much bigger, but it was later narrowed to clear up potential plot holes and headscratchers.
• Dylan was originally meant to marry one of his old female classmates, and the franchise's second half was meant to take place on a post-apocalyptic Earth. Both concepts were scrapped due to them not serving the overall story well enough.
• Non-dinosaurian prehistoric creatures were also meant to appear in the later installments, but they were scrapped to prevent the franchise monikor from becoming an artifact title.

• Action Survivor: Dylan is a mere civilian in this film, but he succeeds in defeating Rexula and (temporarily) saving the world from his vampire virus.
• Antagonist Title: The film's title refers to the big bad: a vampire dinosaur.
• Artistic License – Biology: No creature as massive as Rexula can solely subsist on blood in real life because blood doesn't provide as much nutrition as meat, bones, and fat do, and no real life virus can infect or resurrect dead organisms.
• Artistic License – Paleontology: Rexula's terrestrial form is a palette swap of the male Tyrannosaurus rex from The Lost World: Jurassic Park, and his flying form lacks pycnofibers. Also, his teeth feature internal canals for blood to travel through from his victims' bodies to his bloodstream.
• Big Bad: Rexula is a virus-infected and blood-sucking Tyrannosaurus rex who attempts to obtain clearance to leave Mauna Loa by killing and infecting Dylan's entire immediate family, and he's the main threat of the film.
• Bigfoot, Sasquatch, and Yeti: One of this film's minor plot threads involves Sasquatch being discovered and proven real once and for all.
• Birthday Buddies: When Dylan spends the night with Julie, it's revealed that the 2 cousins share the same birthday.
• Bittersweet Ending: Though losing his entire immediate family is a major downer for Dylan, he still earns himself a chance to eliminate Rexula's creators in the future by eliminating Rexula himself.
• Black Eyes of Evil: Rexula's eyes are mainly black in color (symbolizing his wickedness and biological corruption).
• Blonde, Brunette, Redhead: The film features the aforementioned hair color trio in the form of Emily (blonde), Allison (brunette), and Julie (redhead).
• Bloodless Carnage: Zigzagged:
  • Played straight and justified with Rexula's attacks not ever leaving any blood behind in his victims' corpses.
  • Averted with Clyde's death involving his blood and guts spewing everywhere.
• Blue Is Heroic: Dylan (the hero) wears a blue t-shirt for most of the film.
• Book Ends: The film begins and ends with Dylan sleeping.
• Break Out the Museum Piece: Dylan and his family use an old and obsolete motion-tracker to detect falling debris and Rexula.
• Cataclysm Climax: This film's climax features Mauna Loa's latest eruption decimating the surrounding landscape.
• Central Theme: Once you look past the film's "superficial qualities", you realize that it's centered around the idea of learning how to overcome your personal challenges all on your own.
• Chekhov's Hobby: One of Dylan's favorite hobbies is playing "the floor is lava" with his friends, and it helps him defeat Rexula during the final act.
• Chekhov's Volcano: Mauna Loa is the film's (volcanic) main setting, and it erupts during the climax.
• Climactic Volcano Backdrop: Dylan and Rexula's literal "the floor is lava" game takes place in Mauna Loa's main magma chamber during the final act.
• Clingy Sleepers: At the end of the film, Julie tightly holds onto Dylan from behind him as they go to sleep on Julie's sofa.
• Clone by Conversion: Rexula attempts to transform Dylan's immediate family into perfect carbon copies of himself via infecting it with his virus, but the attempts fail due to Alan, Allison, Derek, and Daniel's bloodless corpses being dumped into the magma.
• Closed Circle: As Rexula endlessly assaults and attempts to assimilate the humans, said humans can't leave Mauna Loa until their helicopter ride home returns (resulting in only one of them getting to go back home alive).
• Color Motif: Red is this film's main "theme color", so it's the color most commonly seen throughout it.
• Composite Character: Rexula sports Darth Maul's skin and eye coloration, Rexy's species identity and manmade origins, and Kane's Son's dark color palette, ability to hide in dark areas, task of single-handedly eliminating a family of humans, and sheer difficulty to defeat without weapons.
• Conservation of Ninjutsu: Invoked and justified. Rexula, a single male vampire Tyrannosaurus rex, proves to be nearly impossible to defeat due to his sheer size, strength, and other biological attributes allowing him to overwhelm an unarmed family of five humans.
• Consistent Clothing Style: Dylan is always seen in t-shirts, shorts, crew socks, and sneakers.
• Convection, Schmonvection: Whenever someone goes near molten rock without touching it, he/she never suffers any ill effects whatsoever.
• Covered in Kisses: Whenever Julie puts Dylan to sleep, she also coats his face with purple lipstick prints.
• Creepy Cave: Mauna Loa's internal passageways are relentlessly patrolled by Rexula and subjected to occasional flooding via molten rock whenever Mauna Loa erupts (meaning they're extremely dangerous and frightening places to be in).
• Cuddle Bug: Julie enjoys tightly cuddling Dylan for hours on end.
• Dark Is Evil: Rexula has (mainly) black skin and eyes, and he's the big bad.
• Darkness Equals Death: Wherever there's darkness, Rexula can easily strike down and eliminate his targets.
• David Versus Goliath: During the climax, Dylan, an average-sized human boy, challenges Rexula, a virus-infected and blood-sucking Tyrannosaurus rex, to a literal "the floor is lava" game (and wins).
• Death of a Child: Despite being preteens and adolescents, Derek and Daniel get killed by Rexula during the film's second half, and despite being 8 years old, Clyde gets killed by Dylan in self-defense during the Post-Climax Confrontation between the 2 boys.
• "Die Hard" on an X: Inverted with Rexula replacing John McClane, the humans replacing skyscraper robbers, and a volcano replacing said skycraper.
• Dwindling Party: Rexula attacks and kills Dylan's immediate blood relatives one after the other until Dylan himself is the only one left alive.
• Early-Bird Cameo: Skeletal Giganotosaurus images are seen via text messages, but the aforementioned species isn't truly introduced until Vampiresaurs: The South American Siege.
• Early-Installment Weirdness: This film features multiple differences from its sequels: the absence of vampire dinosaur eggs, weapons, genetically modified hybrid dinosaurs, Marines, the ability to camouflage within one's surroundings, the standard female vampire dinosaur color palette, the big bad being visible during Dylan's nightmare sequence, major thematic relations to the Godzilla franchise, and subtitles translating the vampire dinosaurs' conversations with one another and the presence of text-message conversations, obsolete technology, a motion-tracker that's its own separate device through and through, microscope examination sequences, freeze-dried food, minimal dinosaur screen-time, an exaggeration of Monster Delay to the point where Rexula is only shown during the last third of the film and the word "dinosaur" isn't spoken until just past the halfway point, the environment playing a major role in the plot, and a flashback sequence.
• Earn Your Happy Ending: Though Dylan is the only one who survives Rexula's attack, he still earns himself an opportunity to save the world from Rexula's creators by dispatching Rexula himself.
• Earthy Barefoot Character: During Dylan's preschool flashback, Emily and Sarah connect themselves to nature by going barefoot on a playground.
• The End... Or Is It?: Once Rexula dies, Dylan believes the vampire dinosaur threat to've been extinguished forever, but footage extracted from a microchip reveals that the vampire dinosaur threat is still alive and well.
• Enemy-Detecting Radar: An old and obsolete motion-tracker is used to detect falling debris and Rexula.
• Evil Is Bigger: Rexula, the big bad, is far bigger and stronger than his human adversaries.
• Expy: Dylan's main character traits (such as him being the one to carry the whole franchise and becoming the sole survivor of his franchise's first installment's dwindling party) are derived from Burt Gummer and Ellen Ripley.
• Extremely Short Timespan: Barring the flashback sequence to 2025, the film takes place over 4 days.
• Family of Choice: Once Dylan loses his entire immediate family to Rexula's attacks, Dylan chooses living with Julie over either living by himself in his old apartment or being "imprisoned" in an adoption center.
• Faster Than They Look: Though Rexula is a giant dinosaur who usually moves slowly to avoid detection, he can run alarmingly fast whenever he has to.
• Fiery Redhead: Inverted. Despite being a redhead, Julie is a friendly, caring, and gentle nurse who loves to take care of Dylan in every way possible.
• Fire Is Red: When Dylan cremates Clyde, the fire emitting from Clyde's body is red in color.
• Forced Transformation: Rexula attempts to forcefully and irreversibly transform Dylan's parents and brothers into perfect carbon copies of himself, but he fails to do so because of his victims' corpses being dumped into molten magma before the vampire virus infection process can be finished.
• Foreshadowing: Many future events (such as Rexula's coming attack, the literal "floor is lava" game played between Dylan and Rexula, Vampiresaurs' entire plot, more vampire dinosaurs coming after humanity following Rexula's death, and Dylan joining the United States Marine Corps) are vaguely hinted at beforehand via character dialogue and visual tidbits.
• Fragile Flyer: Due to its more gracile build, Rexula's flying form is easier to manhandle and kill than his terrestrial form.
• Fragile Speedster: Rexula's flying form is fragile compared to his terrestrial form, but it's also incredibly fast.
• Freudian Excuse: Clyde's motive for antagonizing Dylan involves Dylan not letting him build his own sand castle during their preschool days, them having a fight over the aforementioned matter, and said fight resulting in Clyde getting bitten into and stung by fire ants.
• Gender-Equal Ensemble: The classmate crew features 2 males (Dylan and Edward) and 2 females (Emily and Sarah).
• Gentle Touch vs. Firm Hand: When it comes to how Dylan should be treated every day, Emily believes Dylan should always be treated with direct care and guidance and be allowed to take "baby steps" when it comes to dealing with dangerous situations, making Emily the "gentle touch", whereas Sarah believes Dylan shouldn't receive any direct care or guidance and instead be arbitrarily thrusted into danger at every opportunity possible, making Sarah the "firm hand."
• Giant Flyer: Rexula's flying form is a Quetzalcoatlus, the largest pterosaur ever to exist in real life.
• Girly Girl: Emily is a young girl with a pink color motif, light skin, and a friendly, caring, and gentle personality.
• Glowing Eyes of Doom: Rexula's red pupils always emit a red glow, so if you see bright red lights in the distance, you don't have long to live before you've been bitten into, sucked dry of blood, infected, assimilated, and forcefully transformed into a perfect Rexula carbon copy.
• Good Colors, Evil Colors: Dylan wears a blue t-shirt and white shorts for most of the film, and Rexula has black and red skin and eyes.
• Go-to-Sleep Ending: The film ends with Dylan and Julie going to sleep on a sofa.
• Greater-Scope Villain: Rexula's creators are the larger franchise's ultimate villains, but they have no direct involvement in this specific installment's plot.
• Hair of Gold, Heart of Gold: Emily is an extremely friendly, caring, and gentle girl with blonde hair and a desire to take care of Dylan in whichever ways possible.
• Handy Feet: During the school scene, Emily uses her right foot to pick up a pencil, and during the climax, Rexula uses his flying form's feet to pick up and carry Dylan off.
• Healing Factor: Whenever Rexula gets injured, he can fully recover within seconds.
• Hellish Pupils: Rexula's pupils resemble glowing red circles (further symbolizing his wickedness and biological corruption).
• Hero Killer: Prior to the final act, Rexula kills 4 of this film's heroes: Alan, Allison, Derek, and Daniel.
• High-Pressure Blood: When Clyde dies, a fountain of blood spews everywhere.
• Horror Hunger: Due to being hematophagous, Rexula often has to rest (off-screen) to conserve energy, and when he's active, he relentlessly pursues even the smallest targets because he can't aford to pass up a single blood-cell.
• Humans Are the Real Monsters: Near the end, it's revealed that Rexula was manmade (meaning some humans are even worse than him in terms of morality).
• Implacable Man: Due to his Super-Toughness and healing factor, Rexula is very hard to kill via gruesome injuries, and once he develops a personal problem with a given target, he'll stop at nothing to defeat him/her.
• Improbable Infant Survival: Despite only being 8 years old, Dylan survives Rexula's attack.
• In the End, You Are on Your Own: Zigzagged throughout the final act. From when Daniel dies to when Dylan informs Simon and his friends' families about Rexula's death, Dylan is alone. From when Simon returns to when Dylan gets back to Los Angeles, Simon is with him. From when Dylan walks back to Julie's apartment to shortly after he cremates Clyde and cleans up his (literally) bloody mess, Dylan is alone again, and from when Julie returns home to when the "end credits" roll, Julie is with Dylan.
• It Has Only Just Begun: At the end of the film, the revelation that Rexula was manmade makes Dylan and Julie realize that the former's tussle with Rexula was only the beginning of a much larger conflict.
• "Jaws" First-Person Perspective: Right before Rexula attacks Alan, a glowing red view of everything Rexula sees is briefly shown.
• Jurassic Farce: This film has several features in common with Jurassic Park (1993) (such as the big bad being a genetically engineered Tyrannosaurus rex, the main action taking place on a tropical island, the journey to and from said island being taken via a blue helicopter, a grace period during which the humans stand in awe of the outdoor environment prior to the big bad becoming active, and the protagonist having to tie two like seatbelt parts into a bow).
• Kid Hero: Dylan, an 8-year-old boy, is the film's main hero.
• Kissing Cousins: Despite being Dylan's only living cousin, Julie still kisses Dylan whenever she puts him to bed.
• Kudzu Plot: The film features many plot threads that eventually come together to create a large-scale and complex narrative surrounding Dylan's world, and some of them last into the sequels.
• Lava Pit: Mauna Loa's main internal chamber features a massive magma lake.
• Lava Pot Volcano: Mauna Loa sports a massive lava pit perpetually residing in its main internal chamber.
• Lethal Lava Land: Mauna Loa's interior is a maze of subterranean passageways with magma rivers flowing through large subsections of it and a massive magma pool at its center.
• Lifesaving Misfortune: Edward, Emily, Sarah, and Julie not being able to join Dylan on his camping trip saves them from getting killed by Rexula.
• Lightning Bruiser: Rexula's terrestrial form is extremely strong and fast, making it capable of overwhelming unarmed humans in a split-second.
• Long Hair Is Feminine: Female humans always have longer hair than their male counterparts.
• Mature Work, Child Protagonists: Though this film is a claustrophobic survival horror drama with multiple thematic connections to Alien, it features a young boy as its lead hero.
• May the Farce Be with You: A number of this film's thematic elements (such as a hero with a blue color motif, a villain who's Red and Black and Evil All Over, the villain being a servant of someone even worse than himself, the entire plot only being the beginning of something much bigger, a young boy being involved in the climactic battle, and the 2 main characters "parkouring" through a dangerous environment during the climax) are derived from The Phantom Menace.
• Meaningful Name: Rexula's portmanteau of a name references his species identity and unique status as a vampire dinosaur.
• Mighty Glacier: Subverted. For most of his screen-time, Rexula only moves slowly to avoid detection, but when the going gets tough, Rexula begins moving much faster than before.
• A Molten Date with Death: Rexula dies upon being dumped into Mauna Loa's main magma pool.
• Monster Delay: Exaggerated. During the first two-thirds of the film, Rexula is never shown at all, and even when he's finally seen for the first time, only his left-side jawline and perpetually exposed upper teeth are shown. When Rexula takes Derek down, his entire mouth and legs are shown, and when he takes Daniel down, his eyes and the rest of his face are revealed (followed by his first full-body shot and flying form reveal). Even during the climax, Rexula still doesn't get much screen-time prior to his death.
• Monster Progenitor: Rexula is the first vampire dinosaur ever to exist, and despite his attempts to assimilate Dylan's immediate family to his cause, he fails to do so because of his victims' bloodless corpses getting dumped into the magma.
• Names to Run Away from Really Fast: Don't expect someone with a portmanteau of "Tyrannosaurus rex" and "Dracula" as his name to be nice because such a name perfectly describes his frightening "species identity" and unique physiology.
• Never Bareheaded: Clyde is always seen wearing a purple baseball cap backwards on his head.
• Never Recycle Your Schemes: A heroic aversion. When all three brothers are still alive, Derek proposes that they use bait-and-chase tactics against Rexula, and when the first attempt at such fails, Dylan tries the aforementioned strategy again during the climax (and succeeds).
• Nightmare Sequence: Prior to confronting Rexula, Dylan has a nightmare about being attacked by Rexula.
• No-Gear Level: A justified non-video game example. Due to Dylan's civilian status, federal law forces him to be unarmed during his battle with Rexula, but in this film's sequels, being equipped with state-of-the-art firepower allows Dylan to blast apart countless vampire dinosaurs right and left.
• Noiseless Walker: One reason Rexula is a stealthy colossus is because his footfalls never make any noise whatsoever.
• Normal Fish in a Tiny Pond: From the humans' perspective, Rexula is a nigh-unstoppable monster, but by the franchise's eponymous villains' standards, he's just a mook.
• Nothing Is Scarier: For most of the film, suspense is built around the big bad and the world's other mysteries to create shocking payoffs during the final act.
• Not Quite Dead: When Dylan makes Rexula fall into a deep hole, he (seemingly) dies, only for him to rapidly regenerate and come back to bite Dylan again later.
• Obviously Evil: Rexula's abnormal-looking eyes and foreboding color scheme let you know he's evil just by having you look at him.
• Oddball in the Series: As further explained by the Early-Installment Weirdness entry above, this film is quite different from its sequels in a number of ways.
• An Odd Place to Sleep: Following the opening sequence, Dylan always sleeps either in a tent or on a sofa.
• Omnicidal Maniac: Rexula and his creators are bent on slaughtering all life in the universe in service to Allah.
• The Oner: Certain shots viewed from Dylan's POV can sometimes be up to 3 minutes long.
• One-Word Title: A single-word portmanteau comprises this film's title.
• Our Cryptids Are More Mysterious: Sasquatch, the world's most famous cryptid, is discovered and proven real once and for all during a minor subplot centered around Sarah's Pacific Northwest camping trip.
• Our Slashers Are Different: This slasher film's big bad is a vampire Tyrannosaurus rex infected with a virus that makes him hematophagous and can be used to forcefully transform other entities into perfect carbon copies of him, and this film's main setting is Mauna Loa's interior.
• Our Vampires Are Different: Rexula is different from classical movie vampires in the following ways: a Tyrannosaurus rex instead of a human being his terrestrial form, a Quetzalcoatlus instead of a vampire bat being his flying form, molten rock being what kills him, him being a truly living creature infected with a virus that makes him hematophagous instead of an undead one, him being red and black-skinned and eyed, him never wearing any clothes, him being able to infect, assimilate, and forcefully transform already dead entities into perfect carbon copies of himself with his virus, him using all his teeth to suck blood from his victims, and him being able to rapidly regenerate from horrific injuries. Also, though Rexula is still vulnerable to sunlight, such a weakness never comes into play at any point in the film.
• Pajama-Clad Hero: Julie spends most of her screen-time in her pajamas and bare feet.
• Palette Swap: Many of the human characters' outfits are differently-colored versions of one another, and Rexula resembles a Red and Black and Evil All Over version of the male Tyrannosaurus rex from The Lost World: Jurassic Park.
• Parental Substitute: Julie becomes Dylan's adoptive mother following Alan and Allison's deaths.
• Percussive Maintenance: Dylan and his brothers occasionally bang their fists against their motion-tracker to fix it whenever it malfunctions.
• Pink Means Feminine: Whenever we see Emily, she always wears something pink to flaunt her "girly girl" status, and Allison wears pink pants during Dylan's fateful camping trip.
• Plot Thread: Once Edward, Emily, and Sarah are forcefully separated from Dylan, their stories become temporary "subplots."
• Portmanteau: The film's title is a mashup of "vampire" and "dinosaur", and the big bad's name is a mashup of "Tyrannosaurus rex" and "Dracula."
• Post-Climax Confrontation: After Dylan eliminates Rexula and escapes Mauna Loa's latest eruption, he's confronted one final time by Clyde in Julie's apartment, and when Dylan sees that Clyde wants to kill him with a carving knife for their in-school altercation 4 days prior, Dylan grabs a carving knife of his own, stabs Clyde to death, cremates Clyde, locks away Clyde's ashes in an urn stored in a basement closet, cleans up Clyde's (literally) bloody mess, and never speaks of Clyde again to conclude his conflict with him for good.
• Post-Final Boss: Once Rexula dies, Clyde is the last living source of conflict for Dylan to eliminate and proves to be much less of a threat than Rexula.
• P.O.V. Cam: The film's especially long shots are seen through Dylan's eyes.
• Practical Effects: Rexula, the helicopter rides, and Mauna Loa's interior are mainly portrayed via animatronics and physical sets.
• Predators Are Mean: Rexula is a virus-infected Tyrannosaurus rex with an unending thirst for blood and a sadistic attitude towards attacking people.
• Prefers Going Barefoot: Allison, Emily, Sarah, and Julie deliberately avoid wearing footwear whenever possible, but their shared habit is mainly justified by their desire to connect themselves to nature, make walking and running more comfortable, and use their feet to pick up random objects they find on the ground.
• Puzzle Boss: Since Dylan and company have no weapons, they instead have to draw Rexula into an area where he'll be more prone to falling into the molten magma.
• Quirky Work: This film is mainly centered around a young boy discovering a way to defeat a Tyrannosaurus rex infected with a vampire virus whilst camping in a volcano.
• Real Life Writes the Plot: Part of what lays the groundwork for the vampire virus' creation is the real life COVID-19 Pandemic.
• Real Women Don't Wear Dresses: Allison, Emily, Sarah, and Julie literally never wear any dresses, and the former-most displays zero differences in how she handles Rexula versus how Dylan, Derek, Daniel, and Alan handle the aforementioned dinosaur.
• Red and Black and Evil All Over: Rexula has red and black skin and eyes, and he's an evil vampire dinosaur bent on assimilating and forcefully transforming humanity into perfect carbon copies of himself.
• Red Eyes, Take Warning: Rexula's pupils are glowing red, so if you see them, run away before you get attacked and assimilated.
• Red Is Heroic: Dylan (the hero) wears a red t-shirt during the first act.
• Red Is Violent: Whenever violent events (such as Mauna Loa's latest eruption, Dylan and Clyde's Post-Climax Confrontation, and Rexula attacking people) occur, the color red also crops up.
• Reference Overdosed: This film features many shout outs to other media.
• The Reveal: Several major details (such as the big bad being a vampire Tyrannosaurus rex and the big bad also being manmade) come to light in their own dramatic fashions.
• Rock Beats Laser: Zigzagged. As Rexula slaughters and attempts to assimilate Alan, Allison, Derek, and Daniel, 4 entities smaller, weaker, and less biologically advanced than himself, this trope is inverted, but when Dylan, a fifth entity smaller, weaker, and less biologically advanced than Rexula, beats Rexula in a literal "the floor is lava" game, this trope is played straight.
• Rule of Cool: Though the film's main events are scientifically impossible in real life, they still happen anyway to provide audiences with an unconventional story.
• Rule of Drama: Everything about the film's central conflict is designed to make it so that both sides have to fight very hard and fast to achieve their goals and the audience doesn't know what to expect to happen next.
• Rule of Scary: Many of the film's major plot details (such as the big bad being a vampire Tyrannosaurus rex, the big bad also being manmade, the protagonist being a young boy, the humans having no weapons, the main action taking place in a volcano gearing up for its next eruption, and the horror not ending with the big bad's death) are designed to generate Nightmare Fuel.
• Rule of Three:
  • Out of Dylan's 6 confrontations with the film's antagonists, 3 of them are with Rexula, and the other 3 are with Clyde.
  • The main (human) cast features 3 brothers: Derek, Daniel, and Dylan.
  • Dylan has 3 (named) classmates: Edward, Emily, and Sarah.
  • 3 dinosaur species (Tyrannosaurus rex, Quetzalcoatlus, and Giganotosaurus) are directly featured/referenced throughout the film.
• Saved for the Sequel: Vampiresaurs' entire plot is foreshadowed near the end of this film, but none of it comes to fruition straight away.
• Scary Teeth: Like his real life counterparts, Rexula has 60 massive, serrated, backwards-curved, and bone-crushing teeth that can pulverize a man in a split-second.
• Sequel Hook: The revelation that Rexula was manmade sets up Dylan's future mission to find and eliminate his creators.
• Shapeshifter Default Form: Rexula's main form is a Tyrannosaurus rex.
• Shout-Out: Has its own folder.
• Shown Their Work: Despite many of this film's story elements being scientifically impossible in real life, several real life scientific facts (such as hidden ecosystems living off of bacteria whenever there's no available sunlight, bioluminescent mushrooms, Rexula's fleshy sole-pads making his footfalls dead silent, Rexula sporting perpetually exposed upper teeth and a bone-crushing bite, and Mauna Loa's most recent eruption prior to the film's events occurring in 2022) are also integrated into the story to make it more realistic and interesting.
• Sleep Cute: Dylan and Julie go to sleep together on the latter's sofa at the end of the film (with Julie also clinging onto Dylan from behind him).
• Small Role, Big Impact: Though Principal Eric Smith's screen-time is minimal, it's also what sets up Dylan and Clyde's Post-Climax Confrontation (together with Clyde's death and cremation at the end of it).
• Small Taxonomy Pools: Tyrannosaurus rex, Quetzalcoatlus, and Giganotosaurus are the only 3 dinosaur species featured/referenced in this film.
• Smurfette Principle: Out of the dwindling party, Allison is the only female.
• Sole Survivor: Out of Dylan's immediate family, Dylan himself is the only one who survives Rexula's attack.
• Sorting Algorithm of Evil: Rexula is the beginning of the metaphorical ladder Dylan will have to climb if he wants to become the universe's greatest hero ever, and as far as human villains go, Clyde is the first and least dangerous one Dylan ever faces.
• Spanner in the Works: When Principal Eric Smith suspends Clyde for the first 2 weeks of the following school year, he unknowingly kickstarts the chain of events leading to Dylan and Clyde battling each other after Rexula's death.
• Starter Villain: Despite being the big bad, Rexula is the first and weakest named vampire dinosaur Dylan ever faces, and Clyde is the first and weakest human villain Dylan ever faces.
• Stealthy Colossus: Despite his massive size, Rexula can move around without making any noise whatsoever, so one must be extra vigilant while trying to spot him from a safe distance.
• Stock Dinosaurs: Rexula's 2 forms include a Tyrannosaurus rex and a Quetzalcoatlus, two of the world's most famous dinosaurs, and skeletal Giganotosaurus images are seen via text messages (even though the third aforementioned species doesn't truly appear until Vampiresaurs: The South American Siege.
• Super-Persistent Predator: Rexula endlessly pursues Dylan throughout the climax (no matter how dangerous the environment gets for them both).
• Survival Horror: A large percentage of this film's Nightmare Fuel stems from the humans lacking the resources for dealing with Rexula more effectively than they can with what they already have.
• Suspiciously Stealthy Predator: Rexula's ability to hide in dark areas and perform silent footfalls means he's extremely difficult to spot before it's too late to run away from him.
• Technically-Living Vampire: Instead of being an undead entity reanimated via dark magic, Rexula is a truly living (cloned) entity that's still hematophagous (and can be eliminated via exposure to sunlight).
• Technicolor Fire: When Dylan cremates Clyde, red fire reduces Clyde's body to nothing but soot and ashes.
• Tender Tomboyishness, Foul Femininity: Inverted with Emily being a friendly, caring, gentle, and affectionate girly girl always wanting to keep Dylan out of harm's way and Sarah being a rugged tomboy always wanting to toughen Dylan up by thrusting him into danger at every available opportunity.
• Terrifying Tyrannosaur: A Tyrannosaurus rex serves as Rexula's "default" form, and he's no slouch about using it to terrorize and slaughter unarmed humans.
• Terror-dactyl: A Quetzalcoatlus serves as Rexula's flying form, and he also uses it to frighten his adversaries.
• Tertiary Sexual Characteristics: Allison, Emily, Sarah, and Julie can be distinguished from Dylan, Derek, Daniel, Alan, Mister Dallas, Principal Eric Smith, Clyde, Simon, Stan, Eugene, and Tony by the following differences from the aforementioned male humans: lipstick, nail polish, longer hair, wearing actual sleepwear when going to bed, and their habit of going barefoot whenever possible.
• There Is No Kill Like Overkill: Dylan kills Rexula via making obsidian stalactites push him into Mauna Loa's main magma chamber, melting every last one of Rexula's cells until he can't regenerate ever again.
• They Look Just Like Everyone Else!: Clyde's ordinary clothing and pristine bodily complexion don't immediately give away his status as this film's secondary antagonist.
• Token Nonhuman: Out of all this film's named characters, Rexula is the only non-human one because he's instead a vampire Tyrannosaurus rex.
• Tomboy: Sarah is a young girl with a tan, rugged personality, and often "boyish" interests.
• Tomboy and Girly Girl: Dylan's choice of friends includes Sarah, a rugged tomboy, and Emily, a friendly, caring, gentle, and affectionate girly girl.
• Took a Level in Badass: Dylan starts off as an "average joe" wanting nothing more than to make his way in the world and be with his friends and cousin as much as possible, but when Rexula kills his entire immediate family, he's forced to graduate to an action survivor by killing Rexula and Clyde all by himself.
• To Serve Man: Rexula endlessly seeks out human blood and nothing else to sustain himself most of the time.
• Toxic Dinosaur: Rexula is a vampire Tyrannosaurus rex infected with a virus he attempts to use to forcefully transform his victims into perfect carbon copies of himself.
• Trapped-with-Monster Plot: The film is mainly centered around 5 unarmed humans being stuck in a volcano with a vampire dinosaur attacking and killing them at every turn.
• Trouble Follows You Home: Clyde invades Julie's apartment in an attempt to kill Dylan near the end of the film (meaning even that place isn't safe from Dylan's adversaries).
• Troubling Unchildlike Behavior: At 8 years old, Clyde tries to slaughter Dylan, so in response, Dylan instead slaughters Clyde for his crazed antics.
• 20 Minutes into the Future: Though this film was written in the early 2020s, it takes place in 2030.
• Two Girls to a Team: At the start of the film, Dylan has 2 living (female) blood relatives: Allison and Julie, and Dylan also has 2 named (female) classmates: Emily and Sarah.
• Ultimate Life Form: Rexula's creators engineer him to be this, but he's later revealed to have many biological shortcomings later rectified in the sequels.
• Unwitting Instigator of Doom: Upon suspending Clyde for the first 2 weeks of the following school year, Principal Eric Smith unintentionally creates more conflict for Dylan to foul off later on.
• Villain Killer: During the final act, Dylan kills this film's 2 named villains: Rexula and Clyde.
• Viral Transformation: Once the vampire virus infects Dylan's parents and brothers, it starts forcefully transforming them into perfect Rexula carbon copies, but before the process can be completed, Rexula's victims' corpses are dumped into molten magma.
• The Virus: Rexula's body harbors a vampire virus capable of transforming Rexula's victims into perfect Rexula carbon copies.
• Voluntary Shapeshifting: Rexula can freely switch between his terrestrial and flying forms whenever he wants.
• The War Has Just Begun: When it's revealed that Rexula was manmade (together with his creators silently declaring war on the rest of humanity), Dylan and Julie realize that more vampire dinosaurs will be created in the future (and start making preparations for future battles with them).
• Weaponized Camera: At the beginning of the climax, Dylan uses Derek's cellphone's camera light flashes to briefly stun Rexula until Dylan can head into Mauna Loa's main magma chamber.
• Whole-Plot Reference: This film is Alien but with a lone male vampire Tyrannosaurus rex nicknamed "Rexula" instead of "Kane's Son" the Xenomorph drone, Mauna Loa instead of the derelict Engineer ship and ovomorph chamber directly underneath it, a rundown apartment instead of the USCSS Nostromo, a young boy protagonist instead of a "final girl", a troublemaking boy with a Freudian Excuse for bullying the protagonist instead of a traitorous android, and an unarmed family of 5 instead of a crew of 7 "space truckers."
• Would Hurt a Child: Rexula fully intends to bite into, suck blood from, infect, assimilate, and forcefully transform the 8-year-old Dylan and his preteen and adolescent brothers into perfect carbon copies of himself whenever he's near them. Also, Clyde tries to slaughter Dylan during the film's Post-Climax Confrontation between the 2 boys.
• Xenomorph Xerox: Rexula shares several traits with "Kane's Son", the lone Xenomorph drone from Alien: a mainly black body, the ability to blend in with dark spaces, a habit of trying to trying to forcefully transform his victims into more monsters that are exactly like himself, having to operate completely alone against a dwindling human party, size and strength great enough to prevent his enemies from overpowering him via sheer brute force, being faster than his appearance would suggest, his origins being tied to deliberate genetic engineering via humanoid entities, and the intellectual capacity to behave maliciously towards humans.
• You Can't Go Home Again: Once Dylan's entire immediate family dies, his misfortunate circumstances force him to move into Julie's apartment and sacrifice his old apartment.

• Alien:
  • The plot's main centerpiece involves a lone, nearly unstoppable, dark-skinned, and frighteningly large creature attacking and killing a dwindling human party until only one member of it is left alive.
  • The big bad can hide in dark areas and alcoves due to his dark color scheme, so whenever someone gets too close to him, he can strike him/her down without warning.
  • The big bad usually moves slowly, but when the going gets tough, he can move frighteningly fast.
  • The film also features the protagonist struggling to wake up for breakfast at the beginning, drinking birds, a financial bonus situation, a Slow-Paced Beginning, hardly any action, a coming violent event further complicating matters during the climax, the protagonist only being able to survive by avoiding the big bad most of the time, one last confrontation following the climax, and a Go-to-Sleep Ending.
  • This film is also the only one in its respective franchise to be a straight horror flick through and through (whereas its sequels have other genres thrown into the mix).
  • The film's title forms via having lines and curves coming together at the top of your screen.
  • Even at the beginning, the humans are few in number and can't fight back very well because of their lack of sufficiently deadly items.
  • To compensate for his inability to lay eggs, the big bad reproduces via using his biological properties to corrupt and transform his victims into new monsters that are exactly like himself.
  • This film also features 7 on-screen deaths.
  • The film's One-Word Title, logline, and tagline are designed to instill fear into the hearts of audiences the world over, and the latter two features' wordings are also (partially) modeled after those of the other aforementioned film.
• Aliens:
  • The big bad has a major size and power advantage over the hero and emits the famous "Xenomorph Death-Screech" upon dying.
  • The climax involves a giant monster chasing the protagonists through dark passageways, a coming event that'll be deadly for all entities involved in the action (assuming no one gets to a safe distance first), an aerial vehicle escorting the protagonist away from the main setting, said aerial vehicle narrowing escaping an impending disaster, and the aerial vehicle's pilot saying "It's okay. We're okay." once he and the protagonist have (seemingly) escaped further harm.
• Alien³:
  • The big bad is very fast and moves with his back oriented horizontally.
  • Dead people's bodies are disposed of via dumping them into a molten fluid.
  • A few of the more dramatic moments are viewed in slow-motion.
  • The humans use bait-and-chase tactics to draw their adversary into dangerous areas.
  • The big bad's death involves him getting dumped into the same molten fluid as his dead victims' bodies.
  • The humans have absolutely no weapons (leaving them exceedingly vulnerable to their adversary's attacks).
  • A human antagonist confronts the protagonist during the Post-Climax Confrontation following the non-human big bad's death.
  • The big bad's eyes look just like those of both the new-model Xenomorph drones from the aforementioned film's first (unused) script draft and Sonic.exe.
  • The big bad being able to directly transform his victims into perfect carbon copies of himself (thusly bypassing egg production entirely) is a feature found in Eric Red's unused script draft for the aforementioned film.
• The motion-tracker looks and operates like the one from Alien: Isolation.
• Like Attack of the Clones' eponymous characters, the big bad is grown in a large tank filled to the brim with a life-support fluid.
• The helicopter pilot's surname is derived from Five Nights at Freddy's 2's "Jeremy Fitzgerald" character.
• The way the protagonist and his personal rival's in-school altercation plays out is based on that of ones seen between "troublemakers" and "nontroublemakers" in GoAnimate "Gets Someone Expelled" videos.
• The way the big bad is revealed parallels how Godzilla is revealed in the original Gojira in the following ways: his presence and actions being keenly felt through the discovery and study of his past victims' corpses, the revelation that he's a manmade dinosaur, him not showing up on-screen until well into the film, and him dying while submerged underneath a dangerous liquid.

• Clyde and the plot points associated with him didn't exist at all in the film's original version, but such content was later added to further flesh out Dylan's general social environment.
• Marines are never mentioned in the original version, but the text message from Boris was later added to provide a smoother lead-in to Vampiresaurs.
• The original depiction of Dylan and Julie's relationship was different for the following reasons: meeting each other for the first time, living in different apartment buildings from one another, and Dylan being a frequent "troublemaker" constantly getting brutally punished and barred from meeting her, but the aforementioned details were later removed/changed to make things more realistic and less darkness induced audience apathy-worthy.
• Rexula was initially unnamed, but his name was later added to grant him more characterization.
• Simon's helicopter was meant to run out of electrical charge and leave Dylan stranded in Mauna Loa until the following film, but the aforementioned event was later removed to make the ending less tragic.
• Sarah's Sasquatch hunt was meant to fail at first, but it was later changed to succeed to better fit the film's underlying themes of discovery and the unknown surrounding the natural world.
• Revelations about Edward, Emily, and Sarah's subplots, the Marines' integration into the larger franchise's overarching narrative, the glowing blue mushrooms' salvation from extinction, the motion-tracker's scrapping, Dylan's return to Los Angeles and setting up shop in Julie's apartment, the microchip's study and deciphering, and Mauna Loa's latest eruption weren't meant to happen until Vampiresaurs, but such events were later integrated into this film to make its final act more dramatic and bring multiple plot threads to quicker closes.
• Dylan's friends' fathers were initially unnamed and unmentioned, but they were later added to the story to further flesh out Dylan's friends' families and provide Dylan himself with a way to keep track of his friends' lives more easily whenever he's not with them.

• Absurdly Spacious Sewer: The sewers seen throughout the film are big enough for even the largest theropods and pterosaurs to run and fly through.
• Action Film, Quiet Drama Scene: Especially during the film's first half, many of the scenes are centered around Dylan in his apartment and on the beach as he mainly discusses what moves against the vampire dinosaurs he should make next with his main allies.
• Action Girl: Emily, Sarah, Julie, and Rhonda are prominent female characters with military combat capabilities.
• Action Hero: Dylan graduates to one once he attains US Marine gear and slaughters countless vampire dinosaurs right and left.
• Action Horror: Though Vampiresaur (slightly) delved into this terrority with Dylan playing a literal "floor is lava" game with Rexula, escaping Mauna Loa via supersonic helicopter, and killing Clyde Maverick with a carving knife, this film plays this trope dead straight with numerous US Marines and non-vampire dinosaurs battling even more numerous vampire dinosaurs and tens of thousands dying on each side until every last vampire dinosaur dies.
• Actionized Sequel: While Vampiresaur was a slow-paced and claustrophobic survival horror drama with a science-fiction backdrop, one vampire dinosaur slaughtering an unarmed family of five, and almost no action until the final act, this film is a sci-fi-action film with horror elements, countless vampire dinosaurs led by a Kaiju-sized hive queen, numerous US Marines and non-vampire dinosaurs joining the fray and using energy weapons to eliminate said vampire dinosaurs right and left, and far more action throughout its runtime.
• Advancing Boss of Doom: During the climax, Vampginia relentlessly pursues Dylan and the others until they reach their USS Devastator, and all the Marines can do before the Post-Climax Confrontation with Vampginia is continuously shooting her to (briefly) slow her down.
• The Ageless: This film reveals that the vampire dinosaurs can't die of old age (though they can still be killed through other means).
• Always Chaotic Evil: The vampire dinosaurs are an inherently evil (paramilitary) faction whose unique biological properties make it impossible for them to be heroic under any circumstances.
• Amazing Technicolor Wildlife: Many of the non-vampire dinosaurs boast flamboyant color patterns.
• Antagonist Title: The title refers to the wider franchise's eponymous villains.
• Artistic License – Biology: Continuing on with what was established in Vampiresaur, this film features countless hematophagous dinosaurs (one of which is Kaiju-sized); however, in real life, blood alone can't sustain such massive creatures. Also, real life bee hives have their royal jelly produced via workers that then feed such a substance to a larval female to make her into a future queen, but this film's hive queen (Vampginia) creates it herself and pumps it into one of her eggs to create new queens.
• Artistic License – Military: For starters, the US Marines' uniforms feature holes in their helmets for mohawks and metallic plating covering their torsos (things real life US Marine uniforms don't have), and furthermore, 9-year-olds are never recruited into their ranks in real life.
• Artistic License – Paleontology: Many of the dinosaurs' designs perfectly resemble inaccurate ones from other dinosaur media (with occasional palette swaps).
• Ascended Extra: After only being supporting characters in Vampiresaur, Edward, Boris, Emily, Sarah, and Julie become main characters in this film.
• Attack Its Weak Point: Since Vampginia's eyes and innards are more sensitive than her skin, her enemies target those areas to slow down (and later) kill her.
• Awesome, but Impractical: The Z112-Smart-Blasters and RPG-14s may look like cool weapons to have due to the sheer amounts of damage they can dish out, but they're usefulness is bogged down by their lack of built-in motion-trackers and blue LED flashlight beams.
• Baby Factory: Vampginia's perpetual pregnancy allows her to birth millions upon millions of new vampire dinosaurs day-after-day.
• Barely-There Swimwear:
  • Downplayed with Dylan and Edward's vests and crocs only covering their torsos and feet.
  • Inverted with Emily and Sarah's wetsuits covering their entire bodies aside from their heads, necks, hands, and feet.
• Beach Episode: Though only 2 scenes take place on the beach, this film is mainly set in Los Angeles (which is still a coastal city).
• Behemoth Battle: The giant dinosaurs are frequently shown slugging it out with each other to the death.
• Beware My Stinger Tail: The stegosaurs and ankylosaurs constantly use their spiked and clubbed tails to combat the vampire dinosaurs.
• BFG: The Marines' Z82B-Blaster-Rifles, Z112-Smart-Blasters, and RPG-14s are powerful energy weapons capable of dishing out tons of damage.
• Big Bad: Vampginia is the vampire dinosaurs' hive queen capable of constantly birthing new vampire dinosaurs and giving them orders via roaring.
• Bigfoot, Sasquatch, and Yeti: The Sasquatch from Vampiresaur is mentioned near the beginning of this film.
• Bittersweet Ending: Though Dylan loses his entire hometown to a nuclear detonation, he still manages to kill Vampginia and her entire hive (setting up his later foreign adventures).
• Black Dude Dies First: Out of all this film's named characters, Richard Frost, a tall, muscular, and dark-skinned Ricco Frost expy, is the first one to die.
• Black Eyes of Evil: Like Rexula before them, the male vampire dinosaurs always have mainly black eyes to flaunt their nefarious nature and biological corruption.
• Blonde, Brunette, Redhead: This film still features Emily (blonde), Sarah (brunette), and Julie (redhead).
• Bloodless Carnage:
  • Played Straight and justified with the vampire dinosaurs' attacks always removing every last blood cell from their targets' bodies.
  • Averted with Dylan's hands bleeding whenever they get injured.
• Blue Is Heroic: The Marines wear digital-blue-camouflaged uniforms and operate blue vehicles to let others know they're the heroes in this film's central conflict, and some of the non-vampire dinosaurs have (at least partially) blue bodies. The blaster-bolts the Marines shoot at the vampire dinosaurs are also bright blue.
• Book Ends: Like Vampiresaur, this film begins with Dylan waking up and ends with Dylan going to sleep.
• Boring Yet Practical: As the most commonly used handheld weapon model seen amongst the Marines' arsenal, the Z82B-Blaster-Rifle may not seem as glamorous as its Z112-Smart-Blaster and RPG-14 contemporaries, but what makes it more useful than them is that it's equipped with a built-in motion-tracker and a blue LED flashlight beam.
• Bottomless Magazines: Justified with the heroes' weapons being energy weapons instead of kinetic weapons.
• Bright Is Not Good: Though the female vampire dinosaurs have mainly bright red bodies, they're evil creatures bent on eliminating anyone or anything they deem a threat to them.
• Bug War: A variant featuring vampire dinosaurs as the non-human entities for the Marines to fight. Plus, non-vampire dinosaurs aid the Marines in their efforts.
• Call-Back: This film continues many of the trends established in Vampiresaur: The last 2 title cards displaying a date and the local time, Dylan waking up at the beginning, a "grace period" during which the vampire dinosaur threat is inactive, Dylan having a nightmare about his new adversary, Dylan's main (female) allies occasionally being pajama-clad and walking around barefoot whenever possible, Julie coating Dylan's face with purple lipstick prints whenever she puts him to bed, Dylan and Julie sleeping together on a couch during the film's first half, the vampire dinosaurs hiding in subterranean areas and only striking at night due to their inability to survive being exposed to sunlight, a central color motif appearing throughout the film, the big bad relentlessly pursuing Dylan during the climax, one still-surviving antagonist confronting Dylan after the climax, and Dylan going to sleep after theorizing about what'll come after him next at the end.
• Cannon Fodder: The genetically pure vampire dinosaurs and unnamed personnel on the good guys' side are completely expendable due to their inability to take too much damage without dying en masse.
• Cataclysm Climax: This film's climax features a nuclear detonation vaporizing Los Angeles into a seawater-filled crater.
• The Centerpiece Spectacular: The action sequence occurring on the surface just past the film's halfway point is the film's highest point of action.
• Central Theme: This film's underlying themes mainly deal with not being able to take on certain challenges by yourself.
• Child Soldier: Despite only being 9 years old when this film takes place, Dylan joins the United States Marine Corps to continue his mission to eliminate the vampire dinosaur threat forever, and his 3 (named) classmates also join him on his horrifying adventure.
• Clingy Sleepers: Whenever Dylan and Julie sleep together, the latter tightly holds onto the former to protect him.
• Clone by Conversion: The vampire dinosaurs have far more success in forcefully transforming their victims into perfect carbon copies of themselves via infecting them with their virus than Rexula ever did.
• Color Motif: Blue is the color most commonly seen throughout this film.
• Colossus Climb: From time-to-time, smaller vampire theropods tend to climb all over sauropods whilst attacking them.
• Composite Character: Vampginia sports Zilla's impossibly massive size, susceptibility to missiles, horizontal dorsal posture, bipedal gait, hatred of having one's offspring killed, unique dorsal appendages, and status as the last-living monster once the offspring bite the dust, Count Dooku's Red and Black and Evil All Over color motif and presence during the final confrontation, the male Tyrannosaurus rex's relentless pursuit of the main human protagonist through a coastal city, the Indominus rex's dermal texture, overall body shape, sheer ferocity, and camouflaging capabilities, and the First Acheron Queen's perpetual pregnancy, hermaphroditic sexual identity, protective fury from having her latest brood slaughtered, and involvement in the Post-Climax Confrontation.
• Conservation of Ninjutsu: Due to far greater numbers of entities fighting on each side in this film than in Vampiresaur and tons of energy weapons also being involved in the fight, countless deaths occur on both sides of the aisle.
• Contrasting Sequel Antagonist: While Rexula was a lone, normal-sized, and genetically pure male vampire Tyrannosaurus rex whose only available means of reproduction was using his virus to transform his victims into perfect carbon copies of himself and bodily durability level was the same as that of his real life counterparts, Vampginia is an impossibly massive, nigh-invulnerable, and hermaphroditic hybrid monster capable of endlessly laying massive eggs to drastically increase her hive's population day-after-day.
• Contrasting Sequel Setting: While Vampiresaur was mainly set in Mauna Loa, Earth's largest volcano, this film is set in Los Angeles, one of America's west-coast cities.
• Cool Old Guy: At 61 years old, Carl Sanders is this film's oldest human character, and as the film progresses, he's revealed to be a rather nice guy.
• Covered in Kisses: Julie retains her habit of coating Dylan's face with purple lipstick prints upon putting Dylan to bed from Vampiresaur.
• Cuddle Bug: Julie still enjoys tightly embracing Dylan for hours on end.
• Curb-Stomp Battle: Whenever the herbivorous dinosaurs try to fight Vampginia, such a decision is always a losing proposition because of Vampginia's far greater size, power, and durability allowing her to overwhelm them with ease.
• Damage-Sponge Boss: The only way to kill Vampginia without exposing her to sunlight is by damaging her innards to the point of her blowing to bits from the inside out.
• Dark Action Girl: Every female vampire dinosaur in this film involves herself in the fight to eliminate civilization at all costs, and said females are just as evil as their male counterparts.
• Darker and Edgier: This film features far more violence, deaths, and Nightmare Fuel than its predecessor.
• Dark Is Evil: The male vampire dinosaurs have mainly black skin flaunting their nefarious nature like Rexula before them.
• Darkness Equals Death: Whenever night falls, the vampire dinosaurs head to the surface to slaughter and assimilate every human they encounter, and whenever anyone enters their dark hive beneath the surface, such a decision also gets tons of people killed.
• David Versus Goliath: Like Rexula before her, Vampginia has a tremendous size and power advantage against Dylan, but when they face off during the Post-Climax Confrontation aboard Dylan's USS Devastator, Dylan wins by shooting countless missiles into Vampginia's mouth and blowing her to bits from the inside out.
• Death of a Child: Despite only being 9 years old when this film takes place, Emily gets killed by vampire Pteranodons during the final act.
• Degraded Boss: After being "boss" enemies for Dylan in Vampiresaur, Tyrannosaurus rex and Quetzalcoatlus are now mere mooks for him, but such a phenomenon is justified by Dylan now carrying deadly blaster-rifles when he had no weapons whatsoever before.
• Demoted to Extra: After being the 2 main dinosaur species seen throughout Vampiresaur, Tyrannosaurus rex and Quetzalcoatlus largely fall Out of Focus in this film due to countless other dinosaur species being integrated into the wider franchise.
• Didn't See That Coming: One factor no one anticipates having to deal with later on is Vampginia's ability to become invisible at will (allowing her to ambush the main cast aboard one of the USS Devastators near the end).
• Didn't Think This Through: Halfway through the film, Dylan ventures into the vampire dinosaur hive all by himself in an attempt to destroy it, but he doesn't account for the vampire dinosaurs' sheer numbers being too much for him to handle (forcing him to retreat and face ridicule from the other Marines).
• Distressed Dude: During the climax, Dylan gets captured and brought to Vampginia's lair by a vampire Saurophaganax, forcing Edward, Sarah, and Julie to rescue him before a nuke detonates and vaporizes Los Angeles out of existence.
• *Drool* Hello: When the Post-Climax Confrontation begins, a Triceratops detects Vampginia's presence via spotting her saliva dripping onto his USS Devastator's front deck.
• Early-Bird Cameo: Skeletal images of Dakosaurus, Edgarosaurus, Elasmosaurus, and Styxosaurus appear on Dylan, Edward, Emily, and Sarah's swimwear during the beach scenes, but the aforementioned species never truly appear in the wider franchise until Vampiresaurs: The Asian Infestation.
• Early-Installment Weirdness: As far as the films bearing the plural "Vampiresaurs" moniker go, this film also bears several differences from the wider franchise's 3rd and 4th installments: a One-Word Title, the main heroes not traveling anywhere for the central conflict, no non-American places being visited, the nightmare sequence not occurring right at the film's beginning, the Z80-Grenades not sporting any special variants, non-North American dinosaurs, non-vampire theropods and pterosaurs, unnamed hybrid dinosaurs, and second-in-command hybrid dinosaurs being entirely absent, Dylan getting injured at some point, no erupting volcanoes being involved in the big bad's death, the big bad being involved in the Post-Climax Confrontation, and the vampire dinosaurs occasionally being vaporized on contact with sunlight.
• Earn Your Happy Ending: Not everyone survives the horrific trials they face throughout this film, but those who do get to move on to the phase in their mission to rescue civilization from the vampire dinosaur threat forever: seeking out and eliminating the vampire dinosaurs' creators.
• Earthy Barefoot Character: During the beach scenes, Emily and Sarah connect themselves to nature by walking around barefoot on the sand.
• Elaborate Underground Base: Vampginia's lair is a subterranean laboratory equipped with an elevator-shaft exiting into the sewers, 2 doorways on said elevator-shaft, and blue overhead lights.
• Elevator Action Sequence: Part of the climax involves vampire dinosaurs entering the elevator-shaft and attacking the fleeing Marines.
• Enemy-Detecting Radar: The heroes are now equipped with motion-trackers far more advanced than the one from Vampiresaur (meaning they can detect the vampire dinosaurs from much further away and have different colors for different signal types).
• Energy Weapons: The heroes' new weapons shoot blaster-bolts and lasers instead of bullets.
• Evil Evolves: The vampire dinosaurs gain new powers (such as heightened reproductive potential, the ability to grow up within hours and hatch within minutes, and the absence of language barriers between various species) to counter Dylan's new upgrades.
• Evil Is Bigger: Vampginia, the big bad, is the largest entity seen throughout the film; not even Amphicoelias, the largest ever (real life) dinosaur, is anywhere near as big as Vampginia.
• Explosive Breeder: The dinosaurs' reproductive potential is upgraded to where it's far greater than ever was in real life.
• Expy: Boris, Drake, Richard, Sam, and Rhonda's main character traits are respectively based on those of Dwayne Hicks, William Hudson, Ricco Frost, Trevor Wierzbowski, and Jenette Vasquez from Aliens.
• Extremely Short Timespan: This film takes place over 5 days.
• Family of Choice: By the end, as Dylan sets out to find and eliminate the vampire dinosaur attacks' origin point, the countless Marines and non-vampire dinosaurs he met earlier become new members of his "chosen family."
• Faster Than They Look: Though many of the dinosaurs in this film are massive and may appear slow at times, they can run, fly, and swim at alarmingly fast speeds whenever need be.
• Feed It a Bomb: Dylan kills Vampginia by shooting countless missiles into her mouth and down her throat.
• Fiery Redhead: Inverted with Julie still being a friendly, caring, gentle, affectionate, and redheaded nurse wanting to keep Dylan alive at all costs.
• Final Boss: Vampginia is the final villain for the heroes to fight once her underlings bite the dust.
• Five-Finger Fillet: During the first dining hall scene, Boris repeatedly stabs a carving knife between his, Dylan, and Edward's fingers, but no one gets hurt because of it.
• Flunky Boss: When the Marines flee from Vampginia during the climax, they still also fight her countless descendants.
• Forced Transformation: Whenever the vampire virus infects someone, it always forcefully transforms him/her into a new vampire dinosaur, and once the infection process begins, it can't be reversed under any circumstances.
• Foreshadowing: Boris engaging Julie near the end sets up their wedding taking place near the end of Vampiresaurs: The South American Siege, and the final scene's dialogue drops hints at what'll come after Dylan next.
• Fragile Flyer: The vampire pterosaurs have slender frames that allow them to fly more easily, but such designs make them more susceptible to painful deaths than their theropod comrades.
• Fragile Speedster: The smaller vampire theropods and pterosaurs are extremely fast, but their gracile designs make them easier to kill than their larger theropod comrades.
• Free-Range Children: During the beach scenes, Dylan, Edward, Emily, and Sarah head to and from and spend all their time on the beach without any adults looking out for them.
• Genetic Memory: Rexula's memories lie genetically implanted in Vampginia's brain, providing her with access to knowledge about the Mauna Loa Incident, and when her successor daughter is conceived, she inherits her mother's memories.
• Gentle Giant Sauropod: Every sauropod seen in the film is on the heroes' side.
• Gentle Touch vs. Firm Hand: Emily and Sarah's opposition surrounding how Dylan should be treated and prepared for future dangers introduced in Vampiresaur continues into this film. While Emily still believes Dylan should be directly cared for and allowed to take baby steps towards confronting potential dangers, Sarah still believes Dylan should be thrusted into danger at every opportunity possible (so he can be trained faster).
• Giant Equals Invincible: Vampginia's (external) immunity to the heroes' weapons (together with her massive size compared to every other dinosaur in the film) makes her much harder to kill.
• Giant Flier: Many large-bodied vampire pterosaurs appear throughout the film, and Vampginia's flying form has a 780-foot wingspan.
• Gigantic Adults, Tiny Babies: Vampginia is a Kaiju-sized vampire dinosaur whose babies are always way smaller than her, but the situation is justified by virtually all of them being genetically pure unlike her.
• Girly Girl: Emily retains her feminine schtick and friendly, caring, and gentle personality from Vampiresaur, and her only (potentially) tomboyish trait is her habit of going barefoot whenever possible.
• Glowing Eyes of Doom: The vampire dinosaurs' eyes still glow in the dark (letting you know they're coming for you well ahead of time).
• God Save Us from the Queen!: Vampginia is a massive vampire dinosaur queen with total dominion over her descendants, greater resistance to injury than Rexula, a hybrid genome combining multiple species' deadliest traits into a single creature, a state of perpetual pregnancy that allows her to endlessly lay new eggs, the ability to create a royal jelly-like substance in her abdomen upon taking in sustenance and squeezing it into one of her eggs to create a new vampire dinosaur queen, Rexula's genetic memories implanted into her brain, and the ability to run extremely fast for a creature her size.
• Go for the Eye: During the climax, Dylan briefly slows Vampginia down by shooting her eyeballs.
• Good Colors, Evil Colors: The vampire dinosaurs are always Red and Black and Evil All Over (whereas the Marines and non-vampire dinosaurs constantly boast blue and other colors that are neither red nor black), so it's easy to tell who's good and who's evil just by looking at them.
• Graceful Ladies Like Purple: Julie, the friendly, caring, and affectionate nurse introduced in Vampiresaur, wears purple pajamas during the scene containing Dylan's nightmare sequence.
• Greater-Scope Villain: The vampire dinosaurs' creators still have no direct involvement in this film's plot, but they're still above the vampire dinosaurs in the franchise's villainous hierarchy.
• Guilt-Free Extermination War: Both sides of the wider franchise's central conflict have no qualms about resorting to extreme measures to eliminate the other side.
• Hair of Gold, Heart of Gold: Emily retains her blonde hair color and desire to take care of Dylan in whichever ways possible from Vampiresaur.
• Handy Feet: During the first beach scene, Emily uses her right foot to pick up a clam shell, and during the second beach scene, Emily and Sarah use their feet to dig through the sand for valuable items.
• Harmless Freezing: At first, Vampginia's egg is frozen in cryogenic stasis, and once she's unfrozen, she doesn't suffer any ill effects from said cryogenic stasis.
• Headbutting Pachy: The North American pachycephalosaur species frenquently headbutt their adversaries to defeat them.
• Healing Factor: The glowing mushrooms' health benefits allow consumers to heal faster than normal, and the dinosaurs can still rapidly regenerate whenever they get injured.
• Hellish Pupils: Like Rexula before them, the male vampire dinosaurs have glowing red pupils, so if you see glowing red dots in the distance, it means they've locked onto you.
• Herbivores Are Friendly: Every herbivore seen in the film is on the heroes' side.
• Hermaphrodite: Vampginia is a female vampire dinosaur capable of reproducing all on her own as though she's instead asexual.
• Hero Killer: Throughout the film, the vampire dinosaurs slaughter countless Marines and non-vampire dinosaurs.
• Hive Caste System: Like Xenomorphs, depending on their characteristics, the vampire dinosaurs fall under different categories. Large theropods are analogous to drones. Small theropods and pterosaurs are analogous to runners. Vampire Dilophosaurus specimens are analogous to boilers and spitters. Successor daughters are analogous to praetorians, and Vampginia is analogous to the First Acheron Queen.
• Hive Queen: Vampginia is her hive's ultimate ruler, and she single-handedly maintains order throughout it via loud roars.
• Hollywood Chameleons: Vampginia can become completely invisible at will.
• Horror Hunger: Like with Rexula before them, the vampire dinosaurs' hematophagous nature forces them to rest (off-screen) to conserve energy and pursue even the smallest targets due to every blood-cell they can get into their bodies being extremely valuable, and before breaching the surface, Vampginia constantly swallows up her old eggshells to sustain herself.
• Humans Are the Real Monsters: Though mentions of the vampire dinosaurs' creators take a backseat in this film, said mysterious individuals are still acknowledged as being even worse of a threat to civilization than the vampire dinosaurs whenever someone mentions them.
• Hybrid Monster: Vampginia is a Kaiju-sized vampire dinosaur with a hybrid genome comprised of Tyrannosaurus rex, Stegosaurus, Utahraptor, snake, and cuttlefish DNA.
• Implacable Man: Vampginia is much harder to kill than her underlings as a result of her heightened resistance to injury, and if you try to flee from her, she'll chase you for miles.
• Improbable Infant Survival: Dylan, Edward, and Sarah, 3 9-year-old kids, survive Vampginia and her underlings' countless attacks and live to see this film's ending.
• In the End, You Are on Your Own: (Mostly) averted. When Emily dies, Dylan ends up being alone for part of the climax until Edward, Sarah, and Julie find and rescue him from Vampginia's lair, and afterwards, Dylan is no longer alone for the rest of the film.
• Intimate Healing: The way Emily helps Dylan's hands get better involves her gently squeezing and pressuring his flesh wounds to make them quit bleeding faster, and Emily also relieves Dylan's tension and stress by walking on his back during the second beach scene.
• It Can Think: The vampire dinosaurs are intelligent enough to know how to take down electrical grids.
• Jurassic Farce: This film bears several similarities to The Lost World: Jurassic Park: the dinosaurs now wreaking havoc in a coastal city, this film being Darker and Edgier and featuring more dinosaur species than its predecessor, the dinosaurs showing up quicker than before, the dinosaurs also reaching the coastal city from a tropical island via large ships, and the main human protagonist being more jaded and discontent with the state of his world than before.
• Kaiju: Vampginia's terrestrial form is 1,020 feet long, 412 feet tall at the scalp, and 460 feet tall at the largest dorsal plate's tip, and her flying form has a 780-foot wingspan.
• Kid Hero: Despite his young age, the now 9-year-old Dylan still carries this film's entire plot.
• Kissing Cousins: Julie (Dylan's older cousin) still regularly kisses Dylan upon putting him to bed.
• LEGO Genetics: Vampginia sports the exact genes necessary to create her unique appearance (with no unexpected faults whatsoever).
• Lightning Bruiser: Vampginia is a massive vampire dinosaur with greater strength and speed compared to every other dinosaur in the film.
• Long Hair Is Feminine: Emily, Sarah, Julie, Rhonda, and Ava still sport longer hair than their male allies.
• May the Farce Be with You: Several of this film's thematic elements (such as the previous film's main child star joining a war with profound consequences for his universe, energy weapons that shoot blue blaster-bolts and lasers, the franchise's heroic mooks joining the fray following their previous absence, the villainous mooks being created in vast numbers nonstop, the "blue is heroic" and "Red and Black and Evil All Over" color motifs returning, the main plot being centered around the first (true) battle of a larger war, the big bad being the last villain for the hero to fight near the end, and a romantic relationship upgrade for 2 of the main characters) are derived from Attack of the Clones.
• Mature Work, Child Protagonists: Like in Vampiresaur, Dylan is still a young child as he carries this film's nightmare fuel-laden story.
• Meaningful Name: "Vampginia" is a portmanteau of "vampire" and "Virginia", and it refers to her status as a vampire and a "virgin queen" capable of birthing countless babies all by herself.
• Mighty Roar: The larger (pure-blooded) vampire theropods and Vampginia communicate via loud roars.
• Mix-and-Match Critters: Vampginia resembles a red and black Indominus rex repaint with Stegosaurus dorsal and caudal appendages.
• Monster Delay: Downplayed compared to Vampiresaur. A baby Vampginia appears about 10 minutes into the film, and her adult self and newborn offspring are first shown 10 minutes later during Dylan's nightmare. Adult versions of the pure-blooded vampire dinosaurs also appear 5 minutes after Dylan's nightmare, so in short, the main threat is fully revealed and established less than a quarter of the way into the film's runtime.
• Monster Progenitor: Vampginia is the first vampire dinosaur to be born in this film, and compared to Rexula before her, she has far more success creating new vampire dinosaurs afterwards.
• Monster Threat Expiration: The threat Tyrannosaurus rex and Quetzalcoatlus pose is significantly diminished by the heavy presence of energy weapons and non-vampire dinosaurs, and once Vampginia's weaknesses are discovered, the threat she poses is also diminished.
• Mook Depletion: By the end of the climax, Vampginia loses all her underlings, forcing her to fight all by herself during the Post-Climax Confrontation.
• Mooks: The genetically pure vampire dinosaurs are relatively weak enemies that can be mowed down by Marines and non-vampire dinosaurs.
• More Dakka: To counter the escalating threat posed by the vampire dinosaurs, Dylan is equipped with brand-new weapons deadlier than anything ever invented before.
• Names to Run Away from Really Fast: "Vampginia" is a portmanteau refering to the big bad's status as a vampire dinosaur and "virgin queen" capable of birthing countless new vampire dinosaurs every day (without having sexual intercourse with similarly designed male specimens), and quite a few real life theropod and pterosaur species with frightening names also appear in this film.
• Natural Weapon: The herbivorous dinosaurs often sport unique anatomical appendages designed for defense against predators.
• Never Live It Down: This film kicks off the trend of the Mauna Loa Incident from Vampiresaur always being mentioned throughout the sequels.
• Never Recycle Your Schemes: Every time Vampginia tries to eliminate Dylan, she employs a different method.
• New Powers as the Plot Demands: Due to their genetic upgrades, the vampire dinosaurs attain new powers (such as laying more eggs at a time, having 2 babies emerge from each egg, hatching and growing up far faster than their real life counterparts, producing royal jelly to create new vampire dinosaur queens, understanding each other's noises whenever 2 or more species "speak" to each other, and becoming invisible at will).
• Nightmare Sequence: Before confronting Vampginia, Dylan has a nightmare about Vampginia's successor daughter biting into, sucking all the blood out of, infecting, assimilating, and forcefully transforming him into a new vampire dinosaur monarch.
• Noiseless Walker: The vampire dinosaurs' footfalls still make no noise whatsoever (meaning you can't hear them coming).
• Not Quite Dead: When the nuke detonates, it (seemingly) eliminates the vampire dinosaur threat for the time being, only for Vampginia to attack the heroes once more a short while later.
• Not Zilla: Vampginia being a massive theropod with Stegosaurus plates and spikes also makes her resemble Godzilla's 1998 incarnation.
• No Zombie Cannibals: The vampire dinosaurs never go after each other's blood because they're genetically programmed not to do so.
• Obviously Evil: The vampire dinosaurs' abnormal-looking eyes and foreboding color schemes still let you know they're evil just by having you look at them.
• Oddball in the Series: Not only is this the only Vampiresaur franchise film not to feature volcanic eruptions or the protagonists traveling anywhere, it's also the only Vampiresaur franchise film to feature swimwear, crocs, water-pistols, Dylan getting injured, a named hybrid vampire dinosaur without the ability to shoot airborne vampire virus spores at her enemies, and a contraction in its tagline.
• An Odd Place to Sleep: Dylan and Julie occasionally sleep on the couch from Vampiresaur.
• Omnicidal Maniac: The vampire dinosaurs and their creators are still bent on slaughtering all life in the universe in service to Allah.
• The Oner: Many shots viewed from Dylan's POV last up to several minutes.
• One-Word Title: This film's title only contains one word, and it's a plural version of its predecessor's title.
• Our Vampires Are Different: Due to their biological upgrades, the vampire dinosaurs not only sport the differences from classical movie vampires Rexula sported in Vampiresaur but also sport new differences (such as their female ranks being mainly red with black lateral stripes, 2 babies being able to emerge from each normal vampire dinosaur egg, being able to grow up within hours of hatching, being able to hatch within minutes of having their eggs laid, being led by a Kaiju-sized hive queen with a hybrid genome, being able to create royal jelly-like substances to spawn up new queens, and being able to inherit their ancestors' memories upon conception); however, they can still be killed on contact with sunlight.
• Palette Swap: Some of the vampire dinosaurs' designs are red and black versions of theropod and pterosaur designs from other dinosaur media.
• Parental Substitute: Julie continues her role as Dylan's adoptive mother initiated by Allison's death in Vampiresaur, and once Dylan joins the Marines, Boris becomes Dylan's adoptive father of sorts.
• Pink Means Feminine: Shortly after the centerpiece spectacular, Emily (the team girly girl) wears pink pajamas and pink nail polish.
• Plot-Powered Stamina: The glowing mushrooms grant the Marines enough energy to stay up all night whilst battling countless vampire dinosaurs, but they end up sleeping the next day because of it.
• P.O.V. Cam: Multiple shots are viewed through Dylan's eyes.
• Portmanteau: This film's title is a mashup of "vampire" and "dinosaurs", and Vampginia is a mashup of "vampire" and "Virginia."
• Post-Climax Confrontation: Following the nuke's detonation, it appears as though the surviving Marines and non-vampire dinosaurs have escaped further conflict, only for Vampginia to launch one final attack on them aboard their USS Devastator, prompting Dylan to truly end his conflict with Vampginia by blowing Vampginia to bits from the inside out via countless missiles.
• Practical Effects: Many of the effects seen in the film are performed via animatronics and uniforms.
• Predators Are Mean: Like Rexula before them, the vampire theropods and pterosaurs in this film are blood-thirsty, sadistic, and always chaotic evil monsters bent on converting all their enemies over to their side via infecting them with their virus.
• Prefers Going Barefoot: Emily, Sarah, and Julie still deliberately avoid wearing footwear whenever possible.
• Quirky Work: This entire film is centered around a young boy, his old classmates and only living cousin plus adoptive mother, and countless high-tech Marines and non-vampire dinosaurs battling a massive hive of vampire dinosaurs and its impossibly massive and hermaphroditic hybrid queen.
• Race Against the Clock: Once the nuke's countdown begins, everyone hurries to get everything they must do done before it detonates.
• Raptor Attack: The dromaeosaurs in this film are completely featherless and hunt in packs.
• Real Women Don't Wear Dresses: Emily, Sarah, Julie, Rhonda, and Ava still don't ever wear any dresses, and they're just as adept at fighting vampire dinosaurs as Dylan, Edward, Boris, Drake, Richard, Sam, Carl, and Alvin.
• Recycled Title: This film's title is a plural version of its predecessor's title. In Vampiresaur, there was one vampire dinosaur, but in this film, there are many vampire dinosaurs.
• Red and Black and Evil All Over: Like Rexula before them, the vampire dinosaurs in this film are always red and black in color, so if you see any dinosaurs with those 2 colors, they're to be eliminated at all costs. Even vampire dinosaur eggs are also red and black to indicate the evil lying within them.
• Red Eyes, Take Warning: The vampire dinosaurs' eyes are still partially red to flaunt their nefarious nature and biological corruption.
• Red Is Violent: The vampire dinosaurs are always partially red in color, and their nefarious nature causes them to commit violent acts (such as constantly sucking blood out of other creatures, knocking over and smashing up skyscrapers, stomping terrestrial military vehicles into the ground, and swatting aerial military vehicles out of the air).
• Reference Overdosed: Like Vampiresaur before it, this film features many shout outs to other media.
• Rent-a-Zilla: Vampginia is a massive "verse-based" Kaiju created for this film.
• Rock Beats Laser: Zigzagged:
  • Inverted with the vampire dinosaurs easily defeating unarmed and less biologically advanced humans.
  • Also inverted with Marines armed with powerful blaster-rifles and other energy weapons defeating the vampire dinosaurs who don't have analogues to such technology.
  • Played Straight with the vampire dinosaurs defeating the Marines in spite of their highly advanced weapons.
• Rule of Cool: Those this film's main events are scientifically impossible in real life, they still happen anyway to provide audiences with an unconventional story.
• Rule of Drama: Everything about this film's plot is designed to impose difficulties on both sides of its central conflict and make it so no one knows where it'll take everyone next.
• Rule of Scary: The vampire dinosaurs' biological upgrades and battle tactics are primarily designed to boost this film's "Nightmare Fuel" factor.
• Saved for the Sequel: The possibility of bigger and stronger vampire dinosaur queens eventually being made is discussed near the end of the film, but it doesn't come to fruition until Vampiresaurs: The South American Siege.
• Secondary Sex Characteristics: How a given vampire dinosaur's skin and eye colors are arranged depends on his/her sex, and multiple dinosaur species have anatomical design differences between their sexes.
• Seldom-Seen Species: Many lesser-known dinosaur species (such as Segisaurus, Barosaurus, Amphicoelias, Dromiceiomimus, Dromaeosaurus, Appalachiosaurus, Agujaceratops, and Sphaerotholus) are integrated into the franchise in this film.
• Sequel Escalation: In this film, the stakes are raised from an unarmed family of 5 versus one male vampire Tyrannosaurus rex to many heavily armed Marines and non-vampire dinosaurs versus a hermaphroditic and Kaiju-sized hybrid vampire dinosaur and her gargantuan hive of vampire versions of North American theropod and pterosaur species.
• Sequel Hook: Mentions of possible future events set up the following film: Vampiresaurs: The South American Siege.
• Sequel Non-Entity: Simon Fitzgerald, Mister Dallas, Principal Eric Smith, and the Sasquatch brought back to civilization in Vampiresaur are no where to be seen in this film, even though the former-most and the latter-most are mentioned near the beginning.
• Serial Escalation: When compared to Vampiresaur's main events, this film's main events are escalated in the following ways: the number of dinosaur species featured/referenced being raised from 3 to 365, the number of individual dinosaurs being raised from one to "too many to count", the big bad's length and height stats being raised from 39 feet and 18 feet to 1,020 feet to 460 feet respectively, the number of humans involved in the central conflict being raised from 5 to also "too many to count", the heroes' combat capabilities and vampire dinosaurs' reproductive potential being drastically upgraded, and the setting's geographical range being significantly enlarged from only featuring Mauna Loa's interior to featuring the entire Los Angeles Basin.
• Shapeshifter Default Form: Vampginia's "default form" is an enlarged and red and black Indominus rex with Stegosaurus dorsal plates.
• Shout-Out: Has its own folder.
• Sinister Subway: Once the countless pure-blooded vampire dinosaurs are born, they quickly transform Los Angeles' subway tunnel network into a massive (subterranean) killing field.
• Sleep Cute: Dylan and Julie still occasionally sleep together on their sofa.
• Slow Laser: The heroes' main weapons shoot blaster-bolts and lasers whose movements can be observed in "real-time."
• Small Role, Big Impact: Richard and Sam may be minor characters, but their act of collecting vampire dinosaur DNA samples helps the non-vampire dinosaurs (and everyone else by extension) survive the coming battle against Vampginia and her massive hive.
• Small Taxonomy Pools: Inverted with this film featuring/referencing 365 dinosaur species (many of which are lesser-known and one of which is a fictional hybrid).
• Social Ornithopod: Whenever ornithopods (such as Nanosaurus, Parksosaurus, Hypacrosaurus, Kritosaurus, Lambeosaurus, Brachylophosaurus, Probrachylophosaurus, Protohadros, Tenontosaurus, and Iguanacolossus) are shown, they always travel together in massive herds.
• Sorting Algorithm of Evil: Following Rexula's death in Vampiresaur, Vampginia and her massive hive are the next step up the metaphorical ladder Dylan must climb if he wants to become the universe's greatest hero ever.
• Species Title: Played with. Though the title refers to the main antagonistic (paramilitary) faction, said faction includes every North American theropod and pterosaur species in its ranks.
• Spikes of Villainy: Vampginia's tail sports a Stegosaurus-esque thagomizer due to her unique genetics.
• Stealthy Colossus: Despite her impossibly massive size, Vampginia's invisibility powers allow to remain completely hidden from her adversaries (including their motion-trackers).
• Starter Villain: As far as vampire dinosaur monarchs go, Vampginia is the first and weakest one Dylan ever faces, and that's despite Vampginia being this film's big bad.
• Stock Dinosaurs: Every well-known North American dinosaur species (Tyrannosaurus rex, Allosaurus fragilis, Ceratosaurus nasicornis, Dilophosaurus, Coelophysis, Deinonychus, Troodon, Utahraptor, Ornitholestes, Ornithomimus, Struthiomimus, Triceratops, Pachyrhinosaurus, Styracosaurus, Chasmosaurus, Centrosaurus, Stegosaurus, Ankylosaurus, Euoplocephalus, Edmontonia, Gastonia, Corythosaurus, Edmontosaurus, Parasaurolophus, Saurolophus, Pachycephalosaurus, Stegoceras, Stygimoloch, Dracorex, Brachiosaurus, Apatosaurus, Brontosaurus, Camarasaurus, Diplodocus, Kaatedocus, and Sauroposeidon) appears in this film.
• Stock Footage: Whenever Vampginia and her successor daughter experience genetic memory-induced flashbacks, reused footage from Rexula's microchip recording his death is shown.
• Storming the Castle: The climax involves Edward, Sarah, and Julie infiltrating Vampginia's lair as they rescue Dylan, eliminate Vampginia's successor daughter, and escape the coming nuclear detonation.
• Stuff Blowing Up: A common way of mowing down large numbers of vampire dinosaurs is by blowing up various objects on them.
• Super-Persistent Predator: Once Vampginia leaves her lair, she endlessly pursues Dylan until Vampginia dies during the Post-Climax Confrontation.
• Super-Toughness: Whenever Vampginia gets hit anywhere other than her eyes or innards, she takes no damage whatsoever.
• Suspiciously Stealthy Predator: The vampire dinosaurs constantly use their dark skin and camouflaging abilities to hide themselves from their prey, but such tactics can be (somewhat) countered once the Marines' motion-trackers detect them.
• Tail Slap: One of the sauropods' main combat methods involves slapping the vampire dinosaurs around with their tails.
• Technically-Living Vampire: Like Rexula before her, Vampginia is a truly living and hematophagous dinosaur infected with the vampire virus, and her descendants inherit their vampire virus infections and other unique biological properties from her upon conception.
• Technicolor Fire: Whenever fire shows up, it's always blue in color.
• Tender Tomboyishness, Foul Femininity: The inversion with Emily being a girly girl wanting to keep Dylan away from danger at all times and Sarah being a tomboy insisting on Dylan getting used to being in danger all the time continues into this film.
• Terrifying Tyrannosaur: Vampire versions of every North American tyrannosaur species rise up to antagonize humanity in this film.
• Terror-dactyl: Vampire versions of every North American pterosaur species appear in this film, and they exhibit many disturbing behaviors (such as hanging upside down from ceilings like bats, swarming their targets from above, and slowly walking towards especially vulnerable targets). Vampginia's flying form also resembles an oversized Quetzalcoatlus with Stegosaurus plates and spikes and Utahraptor foot-claws.
• Tertiary Sexual Characteristics: Emily, Sarah, and Julie still sport lipstick, nail polish, longer hair, and less-revealing swimwear, wear actual sleepwear when going to bed, and habitually go barefoot whenever possible, distinguishing them from their male allies.
• There Is No Kill Like Overkill:
  • During the climax, the heroes nuke Los Angeles in an attempt to eliminate the vampire dinosaur threat for the time being, even though such an action results in the formation of a seawater-filled crater.
  • During the Post-Climax Confrontation, Dylan shoots countless missiles into Vampginia's mouth to blow her up from the inside out, and on top of that, the sun also vaporizes Vampginia's exploded remains immediately afterwards.
• Timed Mission: The nuke's countdown sequence only gives everybody 30 minutes to do what they must do during their final night in Los Angeles before the entire city is vaporized out of existence.
• Time Skip: This film takes place one year after Vampiresaur.
• Tomboy: Sarah maintains her rather "boyish" ruggedness throughout this film.
• Tomboy and Girly Girl: Emily maintains her girly girl schtick in this film (whereas Sarah also maintains her tomboy schtick).
• Took a Level in Badass: Dylan graduates from a grizzled action survivor to a true "war hero" via eliminating Vampginia and her massive hive, and Drake grows from a cowardly and wise-cracking man to a battle-hardened survivor willing to do anything to protect his closest allies and eliminate the vampire dinosaur threat for good.
• To Serve Man: The vampire dinosaurs constantly target human blood due to their inferior anatomical designs making them easier to defeat, but they'll still also often target non-vampire dinosaurs' blood.
• Tough Armored Dinosaur: The North American ankylosaur species often hold their own against their adversaries due to their thick armor and deadly caudal weapons.
• Toxic Dinosaur: Like Rexula before them, the vampire dinosaurs constantly try to infect their victims with their virus and forcefully transform them into perfect carbon copies of themselves, and the vampire Dilophosaurus specimens can also shoot venom out of their mouths to blind and paralyze their enemies.
• T. Rexpy: The big bad is a hybrid vampire dinosaur whose base genome is Tyrannosaurus rex DNA.
• 20 Minutes into the Future: Though this film's script was written in the early 2020s, this film is set in 2031.
• Ultimate Lifeform: Vampginia is another attempt at creating such, but she's revealed to have more biological shortcomings later rectified in Vampiresaurs: The South American Siege.
• Urban Warfare: Almost all of this film's main action sequences take place in Los Angeles.
• Vampire Monarch: Vampginia is the first vampire dinosaur queen Dylan ever encounters, and she has total dominion over her hive.
• Vasquez Always Dies: Zigzagged:
  • Inverted with Emily (the team girly girl) dying during a vampire Pteranodon attack and Sarah (the team tomboy) surviving the film's events.
  • Averted with Julie and Rhonda both surviving this film's events, even though Rhonda is also more rugged than Julie.
• Villain Decay: From here, genetically pure vampire dinosaurs become far less menacing (at least by themselves) due to powerful energy weapons being able to slaughter them with ease.
• Villain Killer: By the end of the film, Dylan slaughters countless (normal) vampire dinosaurs and Vampginia.
• Villainous Legacy: Despite his death in Vampiresaur, Rexula's presence is still felt through Vampginia having Rexula's genetic memories implanted into her brain and humanity having now learned to take Dylan's nightmares about the vampire dinosaurs seriously.
• Viral Transformation: Vampire dinosaur transformations are always triggered by the vampire virus infecting someone.
• The Virus: The vampire virus Rexula was once infected with returns to infect, assimilate, and forcefully transform people into new vampire dinosaurs.
• Voluntary Shapeshifting: Vampginia can freely switch between her terrestrial and flying forms whenever she pleases.
• War Comes Home: This film's entire plot is centered around Dylan's war against the vampire dinosaurs being brought to his own hometown.
• War Is Hell: Warring against the vampire dinosaurs has harsh consequences for Dylan (such as losing his entire hometown and one of his closest allies).
• Was Once a Man: Some of the vampire dinosaurs encountered in this film start out as Homo sapiens prior to being infected with the vampire virus.
• Weakened by the Light: Whenever the vampire dinosaurs are exposed to sunlight, it vaporizes them on contact.
• Whole-Plot Reference: This film is Aliens but with vampire dinosaurs of North American theropod and pterosaur species instead of Xenomorph drones as the villainous mooks, an impossibly massive hybrid vampire dinosaur queen instead of the First Acheron Queen as the big bad, Colonial Marines and non-vampire dinosaurs of North American herbivorous species instead of Colonial Marines as the heroic mooks, energy weapons instead of kinetic weapons, waterbound battleships instead of the USS Sulaco as the heroes' main means of transportation, and Los Angeles instead of the LV-426 Hadley's Hope colony station as the main setting.
• The Worf Effect: The herbivorous dinosaurs' sheer size and power allow them to hold their own against their vampire theropod and pterosaur adversaries for most of the film, but once they try to fight Vampginia, she quickly curb-stomps them.
• Would Hurt a Child: Whenever the vampire dinosaurs encounter human children, they always try to bite into, suck all the blood out of, infect, assimilate, and forcefully transform said human children into perfect carbon copies of themselves.
• Xenomorph Xerox: The vampire dinosaurs' Xenomorph similarities established with Rexula in Vampiresaur return in this film, and their biological upgrades introduce new Xenomorph similarities (such as a hive queen having total dominion over her descendants, being able to produce a royal jelly-like substance in her body for the creation of new queens, and showing protective fury over her newborns being slaughtered, heightened intelligence granting them power-cutting capabilities, the absence of language barriers between their different "castes", and alarmingly fast reproductive rates).
• You Can't Go Home Again: Due to a nuke vaporizing the entire Los Angeles Basin out of existence near the end, Dylan and company are unable to continue living there afterwards.
• Zerg Rush: The vampire dinosaurs often swarm their targets en masse to overwhelm them before they can fight back.

• Aliens:
  • The film's title is a plural version of its predecessor's title (meaning the eponymous villains appear en masse instead of as lone individuals this time).
  • The opening titles sequence is visually stylized to where the film opens with a black screen, has multiple blue blurs clearing up to form the film's title, has one of the title's letters brightening its glow until the audience's entire view is engulfed by it, fades to a downwards panning view of a starry screen, and dissolves to a panning shot of the protagonist sleeping.
  • The film begins and ends with the protagonist sleeping.
  • The big bad is a massive hive queen with never-before-seen powers and abilities and total dominion over her descendants.
  • The protagonist joins a plethora of high-tech and highly trained Marines equipped with weapons resembling the Colonial Marines' main weapons.
  • The protagonist's initial efforts to eliminate the villains fail horribly, and he later has to be rescued from the big bad's lair.
  • When the final act occurs, the big bad shows protective fury upon losing her latest offspring, leaves her lair to chase after the protagonist, survives the nuclear explosion, and engages the protagonist one final time during the Post-Climax Confrontation before brutally dying.
  • The big bad's lair is accessed via an elevator-shaft.
  • The heroes use APCs to move around a lot of the time.
  • Many of the Marines are introduced during a dining hall scene and bear the same surnames as the Colonial Marines.
  • The villains cut the power on the heroes by destroying their electrical grid.
  • Several famous lines of dialogue and the tagline are shared amongst these 2 films.
• Like the cloned and Antarctic queens, Vampginia's early life and initial containment are shown on-screen, and like the latter, she eventually breaks herself free.
• Attack of the Clones:
  • The massive conflict having profound consequences for the hero's world truly begins in this film.
  • The franchise's heroic mooks are introduced following their initial absence and battle a massive army of the villainous mooks.
  • The heroes' weapons shoot blue blaster-bolts and lasers.
  • The film covers major exposition prior to any real action and the franchise's central conflict's first true battle.
  • The villains are mass-produced and hang out undergorund whenever they're inactive.
  • The big bad tries to have the hero executed in a horrifying manner but fails and is the only villain involved in the Post-Climax Confrontation.
  • The central conflict's consequences force the heroes to leave their old home for good.
• The herbivorous dinosaurs occasionally attempt to drive off their attackers by bellowing at them like the ones from Disney's Dinosaur.
• The heroes' laser-tanks are (blue) palette swapped versions of the Godzilla franchise's "Mazer-Tanks."
• Godzilla (1998):
  • The big bad is an impossibly massive theropod with Stegosaurus-esque plates and spikes and a realistic theropod gait.
  • The big bad can reproduce all on her own but gets furious once you attack her brood and chases you to the ends of the earth.
  • Despite her massive size, the big bad can hide herself horrifyingly well in densely populated areas.
  • The big bad dies upon being shot with missiles (thereby averting Militaries Are Useless).
  • The big bad bursts out of the ground upon giving chase during the climax.
• Like in The Land Before Time, multiple herbivorous dinosaur species often work together to eliminate their adversaries.
• The Dilophosaurus specimens have cervical frills and can shoot venom out of their mouths like their Jurassic Park/World counterparts.

  • Multiple Tyrannosaurus rexes appear in this film.
  • Many dinosaurs are brought to the mainland via large ships.
  • The hero's personality is more serious and anxious than ever before.
  • The dinosaurs are intelligent enough to know how to open doors.
  • This film's predecessor's setting is absent from this film outside of images and mentions.
• The big bad's impossibly massive flying form can also be compared to Rodan.
• Like in the Star Wars franchise, the heroes' weapons are energy weapons, and the end-credits are bright blue in color.
• The battleships' names dually evoke Devastator from the Transformers franchise and Darth Vader's Imperial I-Class Star Destroyer from Rogue One and A New Hope.

• The film was meant to begin with Dylan still stuck in Mauna Loa and having to escape it once its next eruption begins, but the sequence was later removed and replaced with Dylan being on the beach with Edward, Emily, and Sarah due to the changes made to Vampiresaur.
• Alvin, Richard, Sam, Ava, and the royal jelly-like substance were originally absent, but they were later added to respectively further flesh out Dylan's extended family and provide an explaination for how Vampginia's successor daughter is created.
• Carl and Drake's surnames were meant to be "Samuelson" and "Harrison", but they were later changed to "Sanders" and "Hudson" to reference Kentucky Fried Chicken and William Hudson.
• The big bad was originally unnamed, but she was later named "Vampginia" to give her extra characterization.
• The main blaster-rifles were originally unnamed and shaped differently, but they were later named "Z82B-Blaster-Rifles" and shaped to resemble M41A-Pulse-Rifles to further flesh them out.
• The Z112-Smart-Blasters and RPG-14s were also absent, but they were later added to further expand the Marines' arsenal.
• The vampire dinosaur attack's beginnings originally occurred off-screen, but they were later changed to on-screen events to heighten the "Nightmare Fuel" factor.
• Boris was meant to pick Dylan up following his solo vampire dinosaur hive elimination attempt, but the sequence's conclusion was later changed to Dylan walking back to the USS Devastator by himself to make it make more sense given its initial setup and context.
• A vampire Ceratosaurus was meant to take Dylan to Vampginia's lair, but he was later replaced with a vampire Saurophaganax to make a vampire dinosaur being able to carry Dylan in his mouth seem more believable.
• Sarah was meant to be killed by vampire Pteranodons during the climax, but Emily later took her place as the one to die during such a sequence to make the rest of Dylan's character arc more interesting.
• Julie and Emily were meant to retrieve Dylan from Vampginia's lair, but the sequence was later changed to Edward, Sarah, and Julie rescuing Dylan due to the above point.
• Boris and Julie's engagement was originally absent, but it was later added to show more character development outside of Dylan's daily experiences.

Counting fanworks, I think mine would be this Brandy & Mr. Whiskers saga I came up with as a kid when the show was ongoing. Before I really knew what fanfiction was, or that there was a name for it. It involves Brandy forming a team of other dogs and them going about slaying demons, or something like that. It would "start" with a crossover with The Simpsons where the latter family would end up stranded in the Amazon Rainforest, meet Brandy and Mr. Whiskers, and then soon after it would be revealed that Mr. Whiskers is actually a weakened form of a soul-stealing demon thing in disguise, slowly growing in power and taking the souls of the Simpsons as Brandy gathers tools needed to stop him and free the souls he captured. This also involved a giant Pig Man that could fire powerful energy blasts. And it would end with Brandy leaving the Amazon, with the reveal that her owners were Eddy's family. This was heavily inspired by the Waking the Dragons arc of Yu-Gi-Oh!, and in fact kid-me had some kind of thing where the Legendary Dragons' knight forms were also the "headhunters" we see in the center of the map in the intro (yeah, I don't even have an explanation for how I came up with that "connection") who somehow knew Brandy, and Whiskers was tied to the Great Leviathan or an expy of it.

The final showdown would have Ed, as he and Edd came along with Eddy to rescue Brandy, taking a potion that made him gigantic, and he'd swim across the ocean from the Amazon to Florida while Brandy was on his back, except Ed would get his soul stolen along with everyone on the planet except Brandy as Whiskers would go One-Winged Angel and fight her atop Ed (who... he'd possess or something and force to still swim anyway, even when soulless, to land). Anyway, the whole reason why the showdown was on a giant Ed swimming in the ocean came from the scene from The SpongeBob SquarePants Movie with the fight against Dennis while riding on David Hasselhoff, specifically the console video game's take on it. I drafted some "prequels" (Brandy getting in to some adventures while Whiskers was still acting as though he was just a rabbit, and being somewhat Obviously Evil) and considered potential sequels to it but the Simpsons thing was the main meat that I put effort in to writing. Although I didn't get too far past the part about the giant pig man. Years later, I decided to try my hand at "reimagining" the Simpsons crossover idea in particular as a fanwork in my online story style — the original stories were written on papers that I may or may not still have floating somewhere around my house. I dropped the Yu-Gi-Oh! stuff entirely and removed the Giant Ed plan (the showdown was just set on a boat) but otherwise tried to be faithful to the jist of the original concept. Anyway, the web version of the Simpsons crossover has been published on fanfiction.net and Archive of Our Own, if it's fine to link that. If not, it should be easy to find, being literally the only crossover of those two works I'm aware of.

Oh my god that was longer than I thought it would be. Anyway, I have two runner ups that were also ideas I had as a kid. One was this attempt to turn Squirrel Boy in to an action series where the squirrels learned Elemental Powers (Rodney with fire, Darlene with water, and either Leon or some OC with lightning) and it would go Darker and Edgier, with tons of new animal characters. And the other was this loose set of Sonic the Hedgehog... ideas that I never really wrote down or anything. I don't recall too much of the latter other than having a character named something like "Hyperetica," Shadow had these two clones or something that he basically treated like sons I think, and there was this gag character who was a hedgehog literally just called "Sonic Fan" defined by being an obsessive fan of Sonic to the point of being able to know literally everything he'd do, and I recall "ending" that latter "storyline" by having him come to the conclusion that he's so knowledgeable about Sonic and "in-synch" that he "is Sonic," and he somehow just merges with the actual Sonic? I didn't consider the Fridge Horror behind that back then.

Not counting fanworks, my oddest idea is probably this thing called Ordinary High School I had thought about as a teenager. It was inspired by a Michelle Lyons video^note in one particular channel upload it was called "My Name is Bianca;" in her current channel a quick search of "Bianca" turned up nothing, so it's either not there or it goes by a different name showing heads of a guy and a blue-haired girl on bones. Basically, my idea was about an Ordinary High-School Student being sent in this bizarre school possibly infinite in size and student count that runs on goofy logic and where the dead easily come back, and his main companion was a yandere-ish blue-haired girl that would regularly kill other students that tried to get too close to him (and some others would kill her I think), but it was sorta played off for laughs since death doesn't stick in this Eldritch Location. (Basically picture Happy Tree Friends but less gory.) For the actual plot, I didn't have much in mind except the general dynamic of the deranged blue-haired girl killing or doing something weird, and weirding out MC as the Only Sane Man; I did think of this having an "emotional" ending where, like, when MC graduates he also has to leave the eldritch area and its shenanigans forever, and somehow can't go back to that dimension again or something like that, which actually saddens him since the madness grows on him in a way. A while later I tried to revisit this idea with adult characters, and... at first it went through a lot of changes, first with the "infinite students" being some anomalous dimensional group of people or something, then I turned them in to these self-replicating robots, then I did this superhero story where they were some exponentially-making Literal Split Personality of this Stringy-Haired Ghost Girl-esque woman. The latter I actually did publish, but I'm thinking of rewriting that after I hit a wall in the fourth arc. And very recently, I'm thinking of going back to the "infinite" or at least colossal number-idea of immortals, in a different story that might be a spinoff to the rewrite of that superhero thing. (Where said Stringy-Haired Ghost Girl also either loses the replication or it gets nerfed heavily.)

Come to think of it, I think a reason why "Soos and the Real Girl" stuck with me the way it did was because if you tweak the thing about .GIFfany downloading people to her world, it's... not super far off from the original Ordinary High School idea. That might have sparked some weird nostalgia there.

The runner up for not counting fanworks is this story I did write down a draft of, of a universe where "humans" and the like all generate out of these pools of liquid and are effectively immortal, and they build stuff using this pool of another kind of liquid that allows for Faster Than Light travel, and basically some villain groups use this FTL-liquid to discover a way to kill others. Also everyone was a nudist. Later on, they'd pry in to the secrets of the universe, get attacked by these strange "guardians" that were these living geometric shape-like beings, and then encounter "god," who as it turns out was once a completely ordinary teenager who somehow gained the power to create his own pocket universes (but he couldn't do much in his home world), he made the setting out of boredom, he doesn't really see the creations as their own beings, and is considering wiping them out because he was bored. In short, I scrapped this because after giving it thought, the plot was actually a knockoff of Tengen Toppa Gurren Lagann (the characters made mechas and got in space battles) except with immortality (which also went against said anime's themes), and thinking about it every idea I had at the time just kinda circled back in to doing what TTGL did, but in a different order or something. I saw a WMG or a Fridge entry comparing the final Big Bad of Gurren Lagann to a god and I thought "Damn, that's basically the villain of this story too, it really is a knockoff." I've since kind of took concepts from that and put them in different stories, in particular the main protagonist was reworked as a major character in a much more crass and goofy story about angels and demons, and the "evil god" was also worked in to that same story, although the actual character is very different.

• Absurdly Spacious Sewer: The sewers underneath Buenos Aires and Rio de Janeiro are large enough for even the biggest dinosaurs to fit through.
• Action Girl: Like in Vampiresaurs, Sarah, Julie, and Rhonda are still just as adept at eliminating vampire dinosaurs as their male allies.
• Action Hero: Dylan continues his role as a younger-than-average Marine working to eliminate the vampire dinosaur menace once and for all.
• Action Horror: Like Vampiresaurs, this film generates a thorough blend of horror and action via pitting high-tech Marines and non-vampire dinosaurs against countless vampire dinosaurs and their nigh-invulnerable leaders.
• Actionized Sequel: Exaggerated with this film featuring several massive battle sequences, even more dinosaurs than ever before, the vampire dinosaurs being shown during the very first scene, and new and more violent challenges for the heroes to overcome.
• Always Chaotic Evil: The vampire dinosaurs are still an inherently evil (paramilitary) faction whose unique biological properties make it impossible for them to be heroic under any circumstances.
• Amazing Technicolor Wildlife: Many of the non-vampire dinosaurs still boast flamboyant color patterns.
• Antagonist Title: The title (once again) refers to the wider franchise's eponymous villains.
• Artistic License – Biology: The main villains are even larger and stronger than Vampiresaurs' big bad, but once again, blood alone can't sustain Kaiju-sized creatures.
• Artistic License – Military: The fictionalized Marine gear and practices introduced in Vampiresaurs continue into this film.
• Artistic License – Paleontology: Once again, a fair number of the dinosaurs' designs are palette swaps of outdated designs from other dinosaur media.
• Awesome, but Impractical: The Z112-Smart-Blasters and RPG-14s maintain their impressive appearances and lethal damage output stats in this film, but their overall effectiveness is still bogged down by their lack of built-in motion-trackers and LED flashlight beams.
• Awesome Personnel Carrier: The APCs introduced in Vampiresaurs reappear in this film.
• Baby Factory: Vampginias II-VII can birth even more babies at a time than Vampginia I because of their upgraded genetics.
• Behemoth Battle: The giant dinosaurs are still frequently shown slugging it out with each other to the death.

• Big Bad Duumvirate: This film features 6 vampire dinosaur queens working together as its main villains.
• Bittersweet Ending: Though the vampire dinosaurs are defeated once again by the film's ending, the vampire dinosaurs' true birthplace still isn't discovered, and their creators are still at large.
• Black Eyes of Evil: Like their deceased predecessors, the male vampire dinosaurs still sport mainly black eyes to highlight their wickedness and biological corruption via the vampire virus.
• Bloodless Carnage: Zigzagged. Whenever the vampire dinosaurs suck every last blood cell out of a given target and leave nothing behind afterwards, this trope is played straight, but whenever "The Change" makes blood rain down from an infected victim's body, this trope is averted.
• Blue Is Heroic: The heroes still sport their blue color motifs established in Vampiresaur and Vampiresaurs.
• Book Ends: Not only does this film begin and end with Dylan sleeping, it also begins and ends with Dylan's USS Devastator traversing the world's oceans in search of the vampire dinosaurs' true birthplace.
• Boring Yet Practical: The Z82B-Blaster-Rifles still may not seem as glamorous as the Z112-Smart-Blasters and RPG-14s, but their built-in motion-trackers, LED flashlight beams, and ability to shoot mutliple grenade types grant them greater overall effectiveness than the other energy weapons mentioned.
• Bottomless Magazines: Still justified with the heroes' main weapons being energy weapons instead of kinetic weapons.
• Breaking Old Trends: This is the first film in the Vampiresaur franchise not to feature a One-Word Title and the first one to feature a colon and a distinctive subtitle, and at the end of this film, Sarah (rather than Julie) is the one who puts Dylan to bed and covers his face with green (instead of purple) lipstick prints.
• Breath Weapon: Vampginias II-VII, Spikes, Horns, and Clubs can shoot airborne vampire virus spores out of their mouths.
• Bright Is Not Good: Though the vampire dinosaurs are always partially bright red, they're still pure-evil.
• Bug War: The wider franchise's central conflict involving Marines and non-vampire dinosaurs battling vampire dinosaurs continues into this film.
• Call-Back: This film continues the following thematic traditions already seen in Vampiresaur and Vampiresaurs: beginning and ending with Dylan sleeping, Dylan's face getting covered in lipstick prints whenever his females allies put him to bed, Dylan having a nightmare about his new adversaries before confronting them in "real life", distinct color motifs helping you determine who's good and who's evil, the vampire dinosaurs destroying electrical grids to deny their adversaries access to electricity, the vampire dinosaurs "speaking" to each other in various noises pulled from other dinosaur media with subtitles, the heroes' combat capabilities and the film's dinosaur species roster one-upping what's been seen before, the main villains' body sizes and powers and abilities also one-upping those of their predecessors, a great cataclysm helping to finish off the eponymous villains, at least one still-surviving antagonist confronting Dylan one final time following the climax, and future plot points being set up shortly before the end credits appear.
• Cannon Fodder: The genetically pure vampire dinosaurs and unnamed personnel on the good guys' side are still completely expendable due to their unresolved inability to take too much damage without dying en masse.
• Cataclysm Climax: The climax involves a volcanic eruption helping the heroes eliminate a massive vampire dinosaur "super-hive."
• The Centerpiece Spectacular: The action sequence occurring in the Amazon Rainforest just past the film's halfway point is the film's highest point of action.
• Chekhov's Volcano: Villarrica is a massive volcano that erupts during the climax and helps the heroes eliminate a massive vampire dinosaur "super-hive" that way.
• Chestburster: Dylan's nightmare ends with countless baby vampire Megaraptors bursting forth from his chest and abdomen, and when Clubs bites into Robert, such a bite causes multiple infant Clubs carbon copies to burst out of his chest and abdomen.
• Child Soldier: Despite being 10 years old apiece, Dylan, Edward, and Sarah continue their United States Marine Corps duties in their endeavor to eliminate the vampire dinosaurs forever, and 5 other kids who are either their age or younger also join them on their horrifying adventure.
• Climactic Volcano Backdrop: The climactic sequence takes place near the erupting Villarrica.
• Clingy Sleepers: During the film's first and final scenes, Julie and Sarah tightly embrace Dylan in his sleep to protect him.
• Clone by Conversion: The vampire dinosaurs still use their virus to forcefully transform their enemies into perfect carbon copies of themselves.
• Co-Dragons: Spikes, Horns, and Clubs are "second-in-commands" for the new vampire dinosaur queens.
• Color-Coded for Your Convenience: The newly-introduced grenade variants sports different colors so you can tell which variant is which.
• Color Motif: Orange is this film's main "theme color" (meaning it's the color most commonly seen throughout the film).
• Colossus Climb: From time-to-time, smaller vampire theropods still tend to climb all over sauropods whilst attacking them.
• Composite Character: Vampginias II-VII's main character traits include being impossibly massive theropods with horizontal postures, stegosaur-like plates and spikes, and the ability to reproduce all on their own like Zilla, Red and Black and Evil All Over color motifs like Darth Maul and Count Dooku, being genetically modified hybrids like the Indominus rex and the Indoraptor, and being even bigger, stronger, and more biologically advanced hive queens than their lone predecessor like the two mutant Anchorpoint Station queens.
• Conservation of Ninjutsu: With there being more entities fighting on both sides than ever this time, there are also more deaths than ever, and this trope also manifests in the form of Vampginias II-VII being defeated faster than Vampginia I from Vampiresaur.
• Contrasting Sequel Antagonist: Due to their new genetic upgrades, the new big bads are bigger, stronger, and more biologically advanced and have more powers and abilities than their predecessors, and they also look different from Vampginia I and each other.
• Contrasting Sequel Setting: While Vampiresaur and Vampiresaurs took place in American locations, this film takes place in South America and features deserts, volcanic ash fields, and rainforests (together with the previously explored urban area concept).
• Convection, Schmonvection: Like in Vampiresaur, molten rock never harms anyone as long as no one touches it.
• Cool Old Guy: At 62 years old, Carl is still the wider franchise's oldest human character, and during his last moments of life, he helps to eliminate Vampginia IV.
• Covered in Kisses: During the first and final scenes, Dylan's face is (once again) covered in lipstick prints.
• Creepy Cave: The second act features a cave system infested with vampire dinosaurs.
• Cuddle Bug: During the film's first and final scenes, Julie and Sarah tightly embrace Dylan for hours on end.
• Curb-Stomp Battle: Whenever the non-vampire dinosaurs try to fight the new vampire dinosaur queens and their second-in-commands, they always get slaughtered within a split-second, and during the film's Post-Climax Confrontation between Dylan and said second-in-command vampire dinosaurs, Dylan eliminates his adversaries within a split-second as well.
• Dark Action Girl: Like in Vampiresaurs, the female vampire dinosaurs still involve themselves in the action for the purposes of biting into, sucking blood from, infecting, assimilating, and forcefully transforming their enemies into perfect carbon copies of themselves.
• Dark Is Evil: Male vampire dinosaurs are still partially characterized by their mainly black skin and eyes.
• Darkness Equals Death: Vampire dinosaur attacks still sometimes take place when people venture into dark areas (such as caves, sewers, and subway tunnels).
• David Versus Goliath: Dylan (once again) battles enemies vastly larger and stronger than himself throughout this film (and wins).
• Daylight Horror: Thanks to their new genetic upgrades, the vampire dinosaurs no longer burn up upon being exposed to sunlight (meaning they can now get you on the surface at all times of day).
• Daywalking Vampire: One of the vampire dinosaurs' new genetic upgrades makes it to where they no longer burn up upon being exposed to sunlight.
• Death of a Child: Out of the 5 new kid characters introduced in this film, 4 of them die in rapid succession of one another.
• Degraded Boss: Thanks to the heroes' new combat capability upgrades, Tyrannosaurus rex and Quetzalcoatlus are even easier to defeat than ever (despite them appearing in even greater numbers this time).
• Demoted to Extra: After serving as the mainline mooks in Vampiresaurs, vampire versions of North American theropod and pterosaur species only appear during this film's first act, and afterwards, they're replaced by vampire versions of European, South American, and African theropod and pterosaur species (along with random hybrids between African dinosaur species). The North American herbivorous dinosaur species are also largely pushed aside in favor of the South American herbivorous dinosaur species.
• Desert Warfare: The first major action sequence that isn't a nightmare takes place in the desert-like "Valley of the Moon" in Argentina.
• The Dragon: Every new (male) hybrid vampire dinosaur is a second-in-command for one of the first three vampire dinosaur queens encountered in the film.
• Dragon Their Feet: Spikes, Horns, and Clubs outlive their superiors and confront Dylan one final time near the end of the film.
• Early-Bird Cameo: Multiple Asian dinosaur species are referenced via an image of multiple (non-vampire) hybrid dinosaurs created with their DNA, but Asian dinosaur species aren't properly introduced until Vampiresaurs: The Asian Infestation.
• Earn Your Happy Ending: Again, not everyone lives to see the end of this film, but those who do win the chance to discover and eliminate the vampire dinosaurs' true birthplace and creators once and for all.
• Earthy Barefoot Character: During the first and final scenes, Julie and Sarah still walk around barefoot to connect themselves to nature.
• Elaborate Underground Base: The first three queens seen throughout the film initially reside in orange versions of Vampginia I's subterranean lair.
• Enemy-Detecting Radar: The new-model motion-trackers introduced in Vampiresaurs reappear in this film.
• Energy Weapons: The heroes still use weapons that shoot blaster-bolts and lasers instead of bullets.
• Evil Evolves: The vampire dinosaurs are upgraded (again) to where they now have the power to shoot airborne vampire virus spores out of their mouths and tail-ends, regurgitate vampire virus capsules onto the ground upon taking in sufficient sustenance, have 4 babies emerge from each (normal) egg, hatch out 3 minutes after being laid, reach adulthood 3 hours after hatching, freely choose between virgin birth and traditional sexual intercourse, make new baby vampire dinosaurs grow and develop inside their victims' bodies via non-lethal bites, and lay successor daughter eggs more often (meaning they're a much bigger threat than ever before).
• Evil Is Bigger: The new vampire dinosaur queens are even larger than Vampginia I from Vampiresaurs.
• Explosive Breeder: The vampire dinosaurs' new genetic upgrades allow them to procreate at even faster rates than their predecessors.
• Expy: Many of the new human characters have their main character traits modeled after those of the scrapped human characters from the first draft of William Gibson's unused Alien³ script.
• Extremely Short Timespan: This film takes place over 4 days.
• Family of Choice: By the end of this film, Pablo, Alejandro, Robert, Don, Wade, Elizabeth, Amanda, Adam, Bob, Ben, Harry, Walker, Laura, Michael, Bryson, Haley, Oscar, Henry, and the South American dinosaur species are integrated into Dylan's "chosen family."
• Faster Than They Look: Though their massive size may make them look slow, the dinosaurs are still frighteningly fast and agile.
• Feed It a Bomb: A common strategy for dealing with the vampire dinosaurs still involves shooting grenades into their mouths.
• Fiery Redhead: Inverted with Julie (again) still being a friendly, caring, gentle, affectionate, and redheaded nurse wanting to keep Dylan alive at all costs.
• Final Boss: Vampginias V-VII are the last vampire dinosaurs queens for Dylan to face in this film, and once they're dead, no more new vampire dinosaur queens are ever spawned up again.
• Flunky Boss: Every new vampire dinosaur queen is fought with her underlings helping her out.
• Forced Transformation: Whenever the vampire dinosaurs infect their targets with their virus, said targets are still forcefully transformed into new vampire dinosaurs, and once the initial vampire virus exposure happens, its effects are still irreversible.
• Foreshadowing: Mentions of a possible future vampire dinosaur empress vaguely hint at what Vampiresaurs: The Asian Infestation's big bad will be like, and an image of (non-vampire) hybrid dinosaurs made from Asian dinosaur species DNA hints at the future appearance of Asian dinosaur species in the wider franchise.
• Fragile Flyer: Pterosaurs are still extremely vulnerable to attack due to their slender frames designed for better flight capabilities not helping them shrug off especially strong impacts.
• Fragile Speedster: The smaller vampire theropods and pterosaurs are incredibly fast, but their slender frames make them more vulnerable to attack than their large theropod comrades.
• Fright-Induced Bunkmate: Inverted. In response to Dylan's latest vampire dinosaur nightmare, Julie and Sarah spend the rest of the night in Dylan's top-bunk.
• Genetic Memory: Vampginias II-VII have Rexula and Vampginia I's memories implanted into their brains.
• Gentle Giant Sauropod: Like in Vampiresaurs, the countless sauropods seen throughout the film are always on the heroes' side.
• Giant Equals Invincible: Vampginias II-VII, the largest entities seen throughout the film, are completely immune to blaster-bolts, lasers, and (normal) explosives; however, not-so-normal explosives can still take them down via their special effects (such as poisoning their targets).
• Giant Flyer: Many massive pterosaurs are seen throughout this film, and the named vampire dinosaurs' flying forms are still massive hybrid pterosaurs of some sort.
• Gigantic Adults, Tiny Babies: Vampginias II-VII are Kaiju-sized, but their underlings are always no bigger than real life theropod and pterosaur infants at birth.
• Glowing Eyes of Doom: Again, the vampire dinosaurs' eyes' red portions always glow, so if you see glowing red lights in the distance, you know what's coming for you.
• God Save Us from the Queen!: Vampginias II-VII are even worse in this regard than Vampginia I because of their greater body size, enhanced powers and abilities, leadership over second-in-command hybrid vampire dinosaurs, and immunity to blaster-bolts and lasers.
• Go for the Eye: Non-vampire pterosaurs often target the vampire dinosaur queens' eyes, only for their attacks to not do any damage to them at all.
• Good Colors, Evil Colors: The vampire dinosaurs are still Red and Black and Evil All Over (whereas the heroes still sport different colors from them).
• Go-to-Sleep Ending: Like Vampiresaur and Vampiresaurs, this film ends with Dylan sleeping.
• Greater-Scope Villain: The vampire dinosaurs' creators still have no direct involvement in this film's plot, but they're still worse of a threat than the vampire dinosaurs themselves.
• Group Hug: Following Dylan's latest vampire dinosaur nightmare, Julie and Sarah simultaneously embrace Dylan for the rest of the night.
• Guilt-Free Extermination War: Both sides of the wider franchise's central conflict still have no qualms about resorting to extreme measures to eliminate the other side.

• Hermaphrodite: Vampginias II-VII are female vampire dinosaurs capable of birthing countless new vampire dinosaurs all by themselves.
• Hero Killer: The vampire dinosaurs attack and kill countless more Marines and non-vampire dinosaurs throughout this film.
• Hive Caste System: Like in Vampiresaurs, depending on their biological characteristics, the vampire dinosaurs are placed into different "castes." Large (non-hybrid) vampire theropods are still drones, and small (non-hybrid) theropods and pterosaurs are still runners. Vampire Dilophosaurus specimens are still boilers/spitters. Unnamed hybrid vampire theropods and pterosaurs are analogous to Xenomorph crushers. Spikes, Horns, Clubs, and successor daughter hatchlings are analogous to Xenomorph praetorians, and Vampginias II-VII are analogous to upgraded Xenomorph queens.
• Hive Queen: Vampginias II-VII are the new vampire dinosaur queens ruling over the hives stationed across South America, and they're even bigger and more biologically advanced and dangerous than Vampginia I from Vampiresaurs.
• Horror Hunger: The vampire dinosaurs constantly being on the brink of dying from a lack of sustenance still forces them to stay still for extended periods of time to conserve energy and eat their old eggshells.
• Humans Are the Real Monsters: Like in Vampiresaur and Vampiresaurs, the vampire dinosaurs' creators are still acknowledged as being worse of a threat than the vampire dinosaurs themselves whenever someone mentions them.
• Hybrid Monster: Vampginias II-VII, Spikes, Horns, Clubs, and a fair number of the new mook types are genetically modified hybrid vampire dinosaurs mainly resembling theropods and pterosaurs with herbivorous dinosaur appendages.
• Implacable Man: The vampire dinosaurs are still super persistent predators equipped with Super-Toughness (meaning you'll be in for a rough time once they lock onto you).
• Improbable Infant Survival: Despite being 10 years old apiece, Dylan, Edward, and Sarah survive this film's events, and Michael Alsop, a newly introduced 8-year-old boy, also survives alongside them.
• In the End, You Are on Your Own: This is the only film in the wider franchise to completely avert this trope by not having Dylan get separated from the others at any point during the final act.
• It Can Think: The vampire dinosaurs are still smart enough to know how to cut off their enemies' electrical supply.
• Jungle Warfare: One of the film's main battle sequences takes place in the Amazon Rainforest.
• Jurassic Farce: This film has the following features in common with Jurassic Park III: Spinosaurus vs. T. rex battles, being more action-oriented and heavily focused on the aspect of cloning, hybridization, and the like than its canonical predecessors, multiple pterosaur attack scenes, and the heroes wondering what else the wider franchise's greater scope villains are up to.
• Kaiju: When concerning their terrestrial forms, Vampginias II and V are 1,500 feet long and 500 feet tall at their scalps. Vampginias III and VI are 2,350 feet long and 950 feet tall at their scalps, and Vampginias IV and VII are 3,000 feet long, 1,000 feet tall at their scalps, and 1,300 feet tall at their dorsal sails' tips. As for their flying forms, Vampginias II and V sport 1,800-foot wingspans. Vampginias III and VI sport 1,350-foot wingspans, and Vampginias IV and VII sport 1,000-wingpans.
• Kid Hero: Dylan, now a 10-year-old boy, still carries this film's entire plot.
• Kill It with Fire: Pyro-grenades exist for the sole purpose of burning one's enemies to death.
• Kissing Cousins: Though Julie (Dylan's older cousin) is never actually shown kissing Dylan this time, Julie's purple lipstick prints still cover Dylan's face at the beginning.
• LEGO Genetics: The hybrid vampire dinosaurs still sport the exact genes needed to create their unique appearances.
• Lethal Lava Land: The area surrounding Villarrica briefly becomes flooded with molten rock when the aforementioned volcano erupts during the climax.
• Lightning Bruiser: The vampire dinosaurs are still extremely strong and fast.
• Long Hair Is Feminine: The female humans still sport longer hair than their male counterparts.
• Mature Work, Child Protagonists: Though this is a sci-fi/action horror film laden with copious Nightmare Fuel, the now 10-year-old Dylan still carries its entire plot.
• May the Farce Be with You: This film has multiple features in common with Revenge of the Sith: near-constant action across multiple locations, being Darker and Edgier than its 2 canonical predecessors, the hero still having nightmares about his future, the climactic sequence occurring in a molten lava field, one battle occurring in a jungle, two battles occurring in urban areas, one other battle occurring in a desert, new types of mooks being introduced, and the hero's personality also being Darker and Edgier than before.
• Meaningful Name: The "Vampginia" portmanteau is reused for the new vampire dinosaur queens due to their similarities to Vampginia I from Vampiresaurs, and Spikes, Horns, and Clubs' names refer to what sorts of appendages they have.
• Mighty Roar: The larger (pure-blooded) vampire theropods and Vampginias II-VII still communicate via loud roars.
• Mix-and-Match Critters: Every hybrid vampire dinosaur in this film mainly resembles either a theropod or a pterosaur with herbivorous dinosaur appendages.
• Monster Delay: Averted with the new vampire dinosaurs being fully revealed right at the very beginning of this film.
• Monster Progenitor: Vampginias II-VII are the first of the (new) vampire dinosaurs to be made, and they successfully spawn countless new vampire dinosaurs via various methods (such as infecting people with the vampire virus and laying countless more eggs).
• Monster Threat Expiration: The heroes' new combat capability upgrades make the (normal) vampire dinosaurs even less of a threat than ever (despite their even greater numbers).
• Mook Depletion: Once Villarrica erupts on the "super-hive", every last (unnamed) vampire dinosaur is killed off instantly, denying Spikes, Horns, and Clubs valuable backup when confronting Dylan on the Venezuelan shoreline near the end.
• Mooks: Every unnamed vampire dinosaur is a low-level enemy that can easily be mowed down by the heroes.
• More Dakka: The newly introduced grenade variants provide the Marines with extra offensive output capabilities.
• Names to Run Away from Really Fast: The "Vampginia" portmanteau still means the same thing it did in Vampiresaurs, and Spikes, Horns, and Clubs' names refer to their secondary natural weapons.
• Natural Weapon: Many of the South American herbivorous dinosaur species also sport spikes and clubs for combating their adversaries like their North American cousins.
• Never Live It Down: The Mauna Loa Incident is still mentioned in this film.
• Never Recycle Your Schemes: Zigzagged. When concerning the change in strategy from waiting until dawn to attack to attacking in the dead of night and from not laying extra eggs to hide oneself from their enemies to laying countless new eggs to amass a new army, this trope is played straight, but when concerning the endless habit of destroying one's electrical grids to deny their enemies access to electricity, this trope is averted.
• New Powers as the Plot Demands: Due to their genetic upgrades, the vampire dinosaurs attain new powers and abilities (such as regurgitating vampire virus capsules onto the ground upon taking in sufficient sustenance, shooting airborne vampire virus spores out of their mouths and tail-ends, and having their (non-lethal) bites cause multiple baby vampire dinosaurs to grow and develop inside of whoever they just bit into).
• Nightmare Sequence: Like in Vampiresaur and Vampiresaurs, Dylan has a nightmare about his new adversaries before confronting them in "real life."
• Noiseless Walker: Fleshy sole-pads still allow the vampire dinosaurs to not make any noise whatsoever whilst walking or running.
• Not Quite Dead: During the Buenos Aires, Amazon Rainforest, and Rio de Janeiro battles, Spikes, Horns, and Clubs (seemingly) die, but they later reveal themselves to still be alive near the end.
• Not Zilla: Most of the (hybrid) vampire dinosaurs in this film resemble theropods with stegosaur-like appendages running down their necks, backs, and tails (causing them to resemble Godzilla and Zilla).
• No Zombie Cannibals: The vampire dinosaurs are still genetically programmed to not go after each other under any circumstances.
• Obviously Evil: The vampire dinosaurs still sport their tried and true Red and Black and Evil All Over aesthetic to let you know they're the villains.
• Oddball in the Series: This is the only film in the Vampiresaur franchise to feature multiple big bads, multiple "dragons", jungle warfare, and Dylan not being by himself at any point during the final act.
• An Odd Place to Sleep: For most of the film, Dylan is forced to sleep in an APC seat whenever he needs to rest.
• Omnicidal Maniac: The vampire dinosaurs and their creators are still just as bent on ending all life in the universe as ever.
• The Oner: Dylan's nightmare is an extremely long shot viewed through his eyes.
• Our Vampires Are Different: The vampire dinosaurs further deviate from the "classical movie vampire" image in this film for the following reasons: the ability to regurgitate vampire virus capsules onto the ground upon taking in sufficient sustenance and shoot airborne vampire virus spores out of their mouths and tail-ends and them no longer being vulnerable to sunlight.
• Outgrown Such Silly Superstitions: Averted with this film implying the heroes to be Christians and the wider franchise's greater scope villains to be Muslims.
• Palette Swap: Some of the vampire dinosaurs' designs are still red and black versions of theropod and pterosaur designs from other dinosaur media, and the newly-introduced grenade models resemble differently-colored versions of the standard grenades and each other.
• Parental Substitute: Boris and Julie still serve as Dylan's "surrogate" parents of sorts throughout this film.
• Plot-Powered Stamina: The glowing mushrooms provide the Marines with enough energy to travel thousands of miles per day without getting tired, and the non-vampire dinosaurs are able to keep up with the Marines everywhere they go.
• Portmanteau: The "Vampiresaurs" ("vampire" + "dinosaurs") and "Vampginia" ("vampire" + "Virginia") mashups are still in play in this film.
• Post-Climax Confrontation: After Villarrica erupts on the "super-hive" and eliminates Vampginias V-VII and their unnamed underlings, Spikes, Horns, and Clubs return to confront Dylan one final time before he extracts their DNA and lethally blows them to bits.
• Post-Final Boss: Following the super-hive's extermination, Spikes, Horns, and Clubs (collectively) become zero effort bosses for Dylan to wipe out within seconds.
• P.O.V. Cam: Dylan's nightmare is still viewed through his eyes.
• Practical Effects: Many of the effects seen in the film are performed via more animatronics and uniforms.
• Predators Are Mean: Zigzagged. The vampire versions of the theropod and pterosaur species seen throughout the film are just as evil and sadistic as ever, but their non-vampire counterparts are just as friendly and peaceful as their herbivore comrades.
• Prefers Going Barefoot: When they aren't bound to APC seats during the barracks scenes at the beginning and end of the film, Julie and Sarah deliberately walk around barefoot.
• Quirky Work: This film is centered around a young boy visiting South America to continue his ongoing war with the virus-infected and hematophagous dinosaurs as he also teams up with countless foreign Marines for this installment.
• Raptor Attack: Featherless versions of Austroraptor, Neuquenraptor, Unenlagia, Buitreraptor, and other South American dromaeosaurs are introduced in this film.

• Rent-a-Zilla: Vampginias II-VII are six new Kaiju created for the wider Vampiresaur franchise.
• Rock Beats Laser: Zigzagged. Whenever the vampire dinosaurs defeat Marines equipped with upgraded energy weapons, this trope is played straight, and whenever the Marines' upgraded energy weapons defeat the vampire dinosaurs, this trope is inverted.
• Rule of Cool: Though this film's events are scientifically impossible in real life, they still happen anyway to provide audiences with an entertaining story.
• Rule of Drama: Everything about this film's central conflict is designed to prevent either side from winning too easily and making it so the audience can't tell who's gonna come out on top until one side does.
• Rule of Scary: The vampire dinosaurs' genetic upgrades are designed to amp up this film's "Nightmare Fuel" factor.
• Rule of Three: At first, there are 3 vampire dinosaur queens to deal with, and later, 3 new vampire dinosaur queens are successfully spawned. Also, 3 second-in-command hybrid vampire dinosaurs are seen throughout this film.
• Savage Spinosaurs: Vampire versions of Spinosaurus, Baryonyx, Suchomimus, Irritator, Riojavenatrix, Vallibonavenatrix, Oxalaia, and other spinosaurs are introduced in this film, and they're just as evil, sadistic, and savage as their other vampire dinosaur brethren. Also, Vampginias IV and VII's shared base genome is Spinosaurus DNA.
• Saved for the Sequel: The future appearance of a vampire dinosaur empress is foreshadowed near the end, but she's never actually shown until Vampiresaurs: The Asian Infestation.
• Secondary Sexual Characteristics: The dinosaurs' color arrangement and anatomical design differences established in Vampiresaurs return in this film.

• Sequel Escalation: In relation to Vampiresaurs, this film's plot is escalated from US Marines and non-vampire dinosaurs of herbivorous North American species battling vampire dinosaurs of North American theropod and pterosaur species and their massive queen in Los Angeles to US, Argentinian, and Brazilian Marines and non-vampire dinosaurs of North and South American species battling vampire dinosaurs of North and South American, European, and African theropod and pterosaur species, random vampire hybrids between African dinosaur species, and their six even more massive queens and three second-in-command hybrid specimens across South America.
• Sequel Goes Foreign: While Vampiresaur and Vampiresaurs took place in American locations, this film takes place in South America.
• Sequel Hook: Near the end, dialogue exchanged between Dylan and Sarah foreshadows Vampiresaurs: The Asian Infestation's entire plot.
• Serial Escalation: When compared to Vampiresaurs' events, this film's events are escalated in the following aspects: the number of grenade types being raised from one to five, the number of vampire dinosaur hives being raised from one to four, the number of vampire dinosaur queens being raised from one to six, the vampire dinosaur queens' sizes being enlarged as well, second-in-command hybrid vampire dinosaurs joining the fray, and the number of dinosaur species featured/referenced being raised from 365 to 803.
• Shapeshifter Default Form: Each named vampire dinosaur's "default form" is a hybrid theropod of some sort.

• Slow Laser: The blaster-bolts and lasers seen throughout the film still move slower than light.
• Small Taxonomy Pools: Harshly inverted with this film featuring/referencing 803 dinosaur species (many of which are lesser-known).
• Social Ornithopod: The South American ornithopods (such as Bonapartesaurus, Willinakaqe, Gonkoken, Macrogryphosaurus, and Talenkauen) introduced in this film still always travel in large herds like their North American cousins.
• Sorting Algorithm of Evil: Following Vampginia I's death in Vampiresaurs, Vampginias II-VII, Spikes, Horns, Clubs, and their new hives are the next step up the metaphorical ladder Dylan must climb if he wants to save the universe from the vampire dinosaur threat forever.
• Species Title: Played with. Though the title (again) refers to the main antagonistic (paramilitary) faction, said faction includes every North and South American, European, and African theropod and pterosaur species (along with random (vampire) hybrids between African dinosaur species) in its ranks.
• Spikes of Villainy: Many of the (hybrid) vampire dinosaurs sport spiky bodies due to their genetics.
• Spinosaurus vs. T. rex: Spinosaurus and Tyrannosaurus rex battle each other twice throughout this film.
• Starter Villain: As far as the six new vampire dinosaur queens go, Vampginia II is the first and weakest one Dylan faces, and as far as the second-in-command hybrids go, Spikes is the first and weakest one Dylan faces.
• Stealthy Colossus: The vampire dinosaurs' fleshy sole-pads still allow them to get dangerously close to their targets without being heard.
• Stock Dinosaurs: Not only do the widely-known North American dinosaur species reappear in this film, widely-known foreign dinosaur species (such as Giganotosaurus, Mapusaurus, Eoraptor, Argentinosaurus, Amargasaurus, Dreadnoughtus, Spinosaurus, Megalosaurus, Eustreptospondylus, Carnotaurus, and Herrerasaurus) are introduced in this film.
• Stock Footage: Whenever Vampginias II-VII experience genetic memory-induced flashbacks, reused footage of Rexula and Vampginia I's deaths is shown, and Vampginias V-VII also have reused footage of Vampginias II-IV's deaths play during their flashbacks.
• Storming the Castle: The final act involves the Marines and non-vampire dinosaurs invading and destroying Vampginias V-VII's "super-hive."
• Super-Persistent Predator: Once the vampire dinosaurs lock onto a given target, only death will stop them from claiming him/her/it.
• Super-Toughness: Vampginias II-VII, Spikes, Horns, and Clubs are completely immune to blaster-bolts and lasers, so the only way to beat them is by using poison-grenades on them.
• Suspiciously Stealthy Predator: The vampire dinosaurs can still easily sneak up on people in dark areas.
• Tail Slap: One of the sauropods' preffered methods of combat still involves slapping their enemies around with their tails.
• Technically-Living Vampire: Instead of being undead, the vampire dinosaurs are still truly living and genetically engineered dinosaurs infected with a vampire virus.
• Technicolor Fire: Whenever fire shows up, it's always orange in color.
• Terrifying Tyrannosaur: Vampire versions of North American and European tyrannosaur species help to continue their brethren's reign of terror on humanity in this film.
• Terror-dactyl: Every named vampire dinosaur's flying form is still a hybrid pterosaur of some sort, and vampire versions of many real life pterosaur species appear throughout this film.
• Tertiary Sexual Characteristics: Julie wears purple eyeshadow in this film (visually marking her out as a female amongst her male allies).
• There Is No Kill Like Overkill: The heroes use volcanic eruptions, new grenade variants, and unorthodox battle tactics to slaughter their enemies in all sorts of brutal ways.
• Time Skip: This film is set one year after Vampiresaurs.
• Tomboy: Sarah maintains her rugged and "boyish" personality (along with her tan) in this film.
• Took a Level in Badass: Dylan becomes even more of a badass than ever once he defeats Vampginias II-VII, Spikes, Horns, and Clubs.
• To Serve Man: The vampire dinosaurs still constantly target humans due to their anatomical design weaknesses when compared to those of their non-vampire dinosaur allies.
• Tough Armored Dinosaur: Stegouros, a South American ankylosaur equipped with a uniquely-designed caudal club, is one of the hardiest (heroic) mook types seen throughout the film.
• Toxic Dinosaur: Dilophosaurus specimens still shoot venom out of their mouths from time-to-time, and the vampire dinosaurs still use their virus to infect, assimilate, and forcefully transform their enemies into perfect carbon copies of themselves.
• 20 Minutes into the Future: Though this film's script was written in the early 2020s, this film is set in 2032.
• Ultimate Life Form: Vampginias II-VII, Spikes, Horns, and Clubs are yet more failed attempts at creating such due to their vulnerability to the new grenade variants, but said vulnerability is partially rectified in Vampiresaurs: The Asian Infestation.
• Urban Warfare: Two of this film's main battle sequences take place in Buenos Aires and Rio de Janeiro.
• Vampire Monarch: Vampginias II-VII are the new vampire dinosaur queens presiding over the new vampire dinosaur hives.
• Vasquez Always Dies: Zigzagged with Haley (a newly introduced tomboy) dying and Julie (a not-so-tomboyish nurse), Sarah, and Rhonda (two other tomboyish people) surviving.
• Villain Decay: The normal vampire dinosaurs' threat level is further lessened by the introduction of new grenade variants and Dylan's enhanced experience in dealing with them.
• Villain Killer: By the end of the film, Dylan slaughters Vampginias II-VII, Spikes, Horns, Clubs, and countless unnamed vampire dinosaurs.
• Villainous Legacy: Though Rexula and Vampginia are dead, they aren't forgotten because of their genetic memories being implanted into Vampginias II-VII's brains.
• Viral Transformation: As usual, vampire dinosaur transformations are triggered once the vampire virus infects someone.
• The Virus: The vampire dinosaurs still use their virus to infect, assimilate, and forcefully transform other entities into perfect carbon copies of themselves.
• Volcano Lair: The "super-hive" seen near the end of the film is located in the area surrounding Villarrica (this film's "Chekhov's Volcano").
• Voluntary Shapeshifting: The named vampire dinosaurs can still freely switch between their terrestrial and flying forms whenever they please.
• War Is Hell: Warring against the vampire dinosaurs still has dire consequences for humanity (such as entire cities getting destroyed and people being forcefully transformed into new vampire dinosaurs).
• Was Once a Man: Some of the vampire dinosaurs encountered in this film start out as Homo sapiens prior to being infected with the vampire virus.
• Weakened by the Light: Defied with the vampire dinosaurs' newest genetic upgrades making it to where sunlight can no longer vaporize them on contact.
• Whole-Plot Reference: This film is William Gibson's first unused Alien³ script draft but with genetically upgraded vampire dinosaurs of North and South American, European, and African species (along with random vampire hybrids of African dinosaur species) capable of regurgitating vampire virus capsules onto the ground upon taking in sufficient sustenance and virgin birth instead of new-model Xenomorph drones as mooks, six new vampire dinosaur queens and three second-in-command hybrid vampire dinosaurs capable of shooting airborne vampire virus spores out of their mouths and tail-ends instead of the two mutant Anchorpoint Station queens and new-model Xenomorph praetorians as big bads and Co-Dragons, US and foreign Marines instead of Colonial Marines and foreign scientists as the main human characters, remote-operated APCs instead of remote-operated "power-loaders" as new prototype technology, and South America instead of Anchorpoint Station as the main setting.
• The Worf Effect: The non-vampire dinosaurs' sheer size and power allow them to hold their own against their vampire dinosaur adversaries for most of the film, but once they try to fight Vampginias II-VII, they quickly curb-stomp them.
• Would Hurt a Child: The vampire dinosaurs still attempt to bite into, suck blood from, infect, assimilate, and forcefully transform human children into perfect carbon copies of themselves whenever they get near them.
• Xenomorph Xerox: Due to their new genetic upgrades, the vampire dinosaurs attain new similarities to Xenomorphs: being able to regurgitate vampire virus capsules onto the ground upon taking in sufficient sustenance and having their (non-lethal) bites cause new infant vampire dinosaurs to grow and develop inside their latest victims' bodies.
• Zerg Rush: The vampire dinosaurs still tend to rush towards their enemies en masse and hope for the best.

• The opening titles resemble, transition onto the screen, and sound like orange versions of the "MOTHER" monitor computer texts from Alien.
• Near the end of this film, seeing three vampire dinosaur queens at once mirrors the sight of three Xenomorph Queens in the Aliens: Rescue comic book line.
• The hero having a nightmare about the eponymous villains at the beginning references Eric Red's unused Alien³ script draft's lead hero having a Xenomorph-related nightmare at the beginning.
• The way Robert Tatsumi dies also partially references his thematic counterpart's death in William Gibson's second unused Alien³ script draft (with his body being destroyed before it can be forcefully transformed into another vampire dinosaur).
• William Gibson's unused Alien³ script (first draft):
  • The film features more battles than its direct predecessor.
  • The villains can occasionally regurgitate capsules releasing airborne vampire virus spores to infect suitable hosts and forcefully transform them into new vampire dinosaurs.
  • The new methods of infecting one's victims with the vampire virus is called "The Change", and it occurs with the following events taking place: the host quaking and quivering, the skin coming completely off, blood raining down from the host's body, and the body morphing into a new vampire dinosaur.
  • The Change also affects several non-human animals.
  • Several enemy queens and even more villainous mooks appear throughout this film.
  • The enemy queens are bigger and stronger than the one from the previous film and can shoot airborne vampire virus spores out of their mouths and tail-ends.
  • A massive battle occurs near the end, and the mooks are reduced to their typical level of instinctual action once their queens die.
  • The new human characters sport the same surnames as the ones from the aforementioned unused script draft.
  • When Claws bites into Robert Tatsumi, the bite is non-lethal and causes several Claws carbon copies to burst forth from Robert Tatsumi's chest and abdomen.
  • The characters with the "Walker", "Welles", "Tully", "Brice", "Tatsumi", and "Rosetti" surnames also experience the change under similar circumstances to their thematic counterparts.
  • The ending with the lead protagonist setting out to find and destroy the vampire dinosaur attacks' origin point creates a cliffhanger.
• Three of the vampire dinosaur queens having second-in-command hybrid specimens running around mirrors the relationship between the Antarctic Queen and "Grid" from AVP: Alien vs. Predator.
• The ending featuring a wedding slightly evokes Attack of the Clones and Wreck-It Ralph.
• Destroy All Monsters:
  • The film features multiple battles against impossibly massive theropods across multiple locations.
  • The climactic battle involves (multiple) impossibly massive theropods.
  • After the climactic battle, one last battle occurs during the coming night.
  • Once it's all said and done, everything (temporarily) settles down.
  • At first, the heroes seem powerless to stop their adversaries until they discover what their true weaknesses are.
  • The main villains also occasionally burst out of the ground upon making their grand entrances.
• The sequence with the Marines and non-vampire dinosaurs traveling across a South American desert is based on a similar sequence in Disney's Dinosaur.
• This film features a "middle-of-the-story" plot like The Empire Strikes Back.
• The way Vampginia II eliminates fighter-jets and helicopters is strikingly similar to how Rodan does so in Godzilla: King of the Monsters (2019).
• The orange end credits evoke the first three Jurassic Park films.
• Jurassic Park III:
  • The film features 2 Spinosaurus vs. T. rex battles.
  • The film features more dinosaur action and delves more heavily into the concepts of cloning, hybridization, and the like than its 2 predecessors.
  • The film also features multiple pterosaur attacks.
  • The latest story developments make the heroes wander what else the wider franchise's greater scope villains are up to.
  • One newly introduced character has "Amanda" as her first name.
• Revenge of the Sith:
  • The film features near-constant action across multiple locations and is Darker and Edgier than its 2 predecessors.
  • The lead protagonist still has nightmares about his near-future.
  • During the climax, the heroes use the volcanic environment against their adversaries.
  • The film also features one jungle battle, one desert battle, and 2 urban area battles.
  • New mook types for both sides debut in this film.
  • The hero also becomes more jaded, serious, and anxious than ever.
• The newly acquired power to shoot airborne vampire virus spores out of one's tail-end also evokes Shin Godzilla's "atomic breath" coming out of his tail-end.
• The tagline is partially based on Spider-Man 3's tagline.

• Original story treatment:
  • The film's original version was titled "Vampiresaur III" and featured a lone male (cybernetically enhanced, Kaiju-proportioned, and nameless) vampire Giganotosaurus as its big bad, no non-vampire theropods or pterosaurs, Julie dying at the big bad's hands near the end, nukes simultaneously detonating and eliminating every last city, town, and village on Earth, and the remaining heroes being forced to live in Mauna Loa for the next 30 years, but the aforementioned plot threads were later changed/removed entirely for the following reasons: removing a plot hole surrounding the return to one vampire dinosaur when countless more at a time can be made, preventing the villains' upgrades from becoming too far-fetched, furthering the heroes' combat upgrades, and preventing the ending from being too bleak stopped caring-inducing.
  • Emily was meant to appear in the film, but due to the changes made to Vampiresaurs, her appearance was scrapped and replaced with Sarah's continued role in the wider franchise.
  • The vampire virus capsules, airborne vampire virus spores, "The Change", and non-lethal bites' ability to make multiple baby vampire dinosaurs burst forth from other organisms' chests and abdomens were entirely absent, but they were later added to make the film be thematically closer to William Gibson's first unused Alien³ script draft.
  • Pablo Suslov, Alejandro Jackson, Adam Spence, Bob Trent, Elizabeth Welles, Amanda Tully, Wade Fox, Robert Tatsumi, Don Halliday, Laura Rosetti, Ben Braun, Harry Shuman, Harold Walker, Michael Alsop, Bryson Greenfield, Haley Brice, Oscar Costello, and Henry Wallace were also absent, but they were later added to further flesh out Dylan's extended family.
• Second story treatment:
  • The film's second version was titled "Vampiresaurs: The Siege of South America" and introduced the six queens and their multiple hives concept, non-vampire theropods and pterosaurs, Sarah's appearance, Pablo, Julie's survival and marriage to Boris at the end, and the vampire virus' ability to forcefully transform vampire dinosaur attack victims into new vampire dinosaurs, but more specific details surrounding said introductions were later changed/expanded upon due to more objective quality issues needing to be ironed out.
  • The cybernetically enhanced vampire dinosaurs concept was still present, but it was later removed due to the reason mentioned above.
  • The six queens were unnamed, but they were later named Vampginias II-VII due to other changes made to Vampiresaurs.
  • The vampire virus capsules, airborne vampire virus sprores, "The Change", multiple baby vampire dinosaurs bursting out of other organisms' chests and abdomens, new human characters other than Pablo, and second-in-command hybrid vampire dinosaurs were still absent, but they were later added for the reasons mentioned above.
  • Pablo's original surname was "Henderson", but it was later changed to "Suslov" to better fit the Alien³ (William Gibson's first unused script draft) vibes.
  • The heroes were meant to stay in South America and have their current enemy type stick around after the climax, but such ideas were later dropped in favor of a more natural progression of the franchise's larger narrative.
  • Though the first queen fought and killed in the film and her successor daughter were already identical to how they are in the film's final version, the second queen fought and killed (along with her successor daughter) sported Kentrosaurus DNA, and the third queen fought and killed (along with her successor daughter) sported Huayangosaurus DNA (meaning Asian theropods and pterosaurs were also previously intented to appear in the film). The latter four queens' secondary genomes were later replaced with Isaberrysaura and Kentrosaurus DNA (removing Asian dinosaurs from the film entirely outside of an image featuring non-vampire hybrid dinosaurs created via Asian dinosaur DNA near the end).
  • The three queens fought near the end weren't meant to run a "super-hive", but such a concept was later added to make the final act more exciting.
  • Vampire versions of the North American theropod and pterosaur species were meant to be absent from the film, but they were later added into the first main action sequence to show that they're still being produced and make the film as a whole feel more like a natural continuation of Vampiresaurs.
