Dinosaurs
Horned Tyrannosaurs
- Attack of the 50-Foot Whatever: The alpha is gigantic, at the size of a sauropod. It's understandable if you mistake its normal-sized pack members as its children.
- Bizarre Sexual Dimorphism: The Grand Finale implies that Fang is a female individual of the Horned Tyrannosaur species, as her son develops similar horns as them, horns that his father lacked.
- Evil Is Bigger: Most of them are slightly bigger than Fang, the sympathetic Tyrannosaurus, and their leader is humongous, with a body length between 20 and 30 meters.
- Horns of Villainy: All of them have horns (two of them having a Ceratosaurus-like horn, another a horn arrangement like an African rhinoceros, and the last one small hornlets on the snout similar to Alioramus), which the more sympathetic Tyrannosaurus Fang lacks.
- Informed Species: Downplayed in that, despite their horns, they possess the general body size (save for the sauropod-sized alpha), proportions, and two-fingered hands of Tyrannosaurus. Although the one with the most (and smallest) horns is the closest looking to a real Tyrannosaurus.
- Made of Plasticine: As typical for a gory series. Spear can kill one of them by throwing a spear through its torso like a bullet. Though downplayed, the absence of a brutal death for the third member of the trio during Spear and Fang's fight with them implies that Fang successfully killed it by caving its head in with a Tail Slap.
- Mighty Glacier: The alpha tyrannosaur is absolutely the largest of the pack whose attacks were so lethargic that Spear and Fang can easily dodge almost every attempted strike. However, it did put up more of a fight than the others did as one Tail Slap from the beast sent Fang flying at least several feet away as well as smacking her into the ground with a measly claw swipe.
- Mix-and-Match Critters: They are the correct size and shape for a T. rex, but they have horns like rhinos, Ceratosaurus, or Alioramus.
- Monstrous Cannibalism: The Horned Tyrannosaurs are either the same species as Fang or at least a closely related species. This does not stop them from seeing Fang's offspring as prey. Truth in Television in that their species really were cannibalistic.
- Non-Malicious Monster: They're just predators targeting what they think are prey.
- Only a Flesh Wound: Spear bashes one of the horned tyrannosaurs' legs in with a rock, resulting in a compound fracture, but after a few seconds of screaming it just snaps the leg back into place and keeps attacking like nothing happened, though it does seem to have a limp for the short period it survives after fixing its leg.
- Red and Black and Evil All Over: They are a dark shade of red with prominent black stripes.
- Starter Villain: Their killing of their families made them the first foes that Spear and Fang fight together.
- Terrifying Tyrannosaur: Despite their horns, all of them are identified in the animatic as T. rex, and they are shown to be fierce, bloodthirsty creatures. Their alpha is also gigantic, at least twice the size of the largest real life tyrannosaurs.
- Would Hurt a Child: They have no issue seeing children, human or dinosaur, as their next meal.
- Your Size May Vary: The alpha is enormous, but how big it varies from scene to scene. In its first appearance, it seems gigantic, with the other tyrannosaurs looking like infants next to it; in the scene where it attacks Fang's babies, it only seems slightly larger than its other pack-members.
Raptors
- Book Ends: They are seen in the beginning chasing down Fang and Spear. They appear in the end when Spear decides to lure the giant bats into the tall grass where the raptors live so they can deal with each other.
- Chekhov's Gunman: They appear at the start of the episode and become important in the duo's escape strategy from the flock of bats, as the duo lure the bats into the same tall grass they live in.
- Homefield Advantage: They refuse to pursue Spear and Fang into the territory of the giant bats after sundown and return to the field of tall grass but when the bats are lured into the same field at sunrise, they have no qualms about attacking them and seem to have the advantage.
- One-Hit-Point Wonder: One strike from Spear's weapon or one bite from Fang is usually enough to kill them.
- Raptor Attack: They have the classic scaly raptor look popularized by Jurassic Park. However, they are roughly correctly sized for Deinonychus.
- Set a Mook to Kill a Mook: At the end of the episode, Spear and Fang run into the tall grass to get the raptors to engage the bats chasing them.
- Zerg Rush: Their attack strategy is based only on numbers. The pack that attacks Spear and Fang consists of about a hundred individuals (most of which die from a single hit).
Argentinosaurus
A herd of sauropods living peacefully in a valley, until one of them gets infected with a plague.
- All There in the Manual: David Krentz, who wrote the episode, confirmed
◊ the sauropods to be Argentinosaurus. The animatic, however, just calls them "sauropods". - Artistic License – Paleontology: They are depicted chewing their food and galloping, neither of which sauropods are capable of in real life. The artists also make the fairly common mistake of putting sauropod nostrils on their foreheads. While this is indeed where the nostril openings are on the skulls of most sauropods, the actual fleshy nostrils would've been in a more typical location further down on the snout. Additionally, while their forefeet are accurately designed (with the thumb claw being the only visible digit), their hindfeet have four claws in certain shots whereas almost all advanced sauropods had only three.
- Gentle Giant Sauropod: Normally. They are inoffensive for their large size but will fight back if they have to, such as the infected one hurling the infected hadosaur after it bit it with enough force to finish it off, or how one of them tries to subdue the now-mad victim when it tramples the herd's eggs only to be the next to die.
- Informed Species: Their heads are more like that of Camarasaurus, likely because Argentinosaurus was sometimes restored this way. Their forefeet also have phalangeal bones, whereas real titanosaurs walked on their knuckles.
- Red Shirt: The rest of the herd end up being killed by their diseased member.
- Screw This, I'm Out of Here!: The last Argentinosaurus just tries to run as fast as it can from the massacre. Unfortunately for it, the plague monster quickly catches up and body-slams it into the sharp branches of a massive tree, impaling it to death.
- Shown Their Work: They correctly have only a single claw on the forefoot like a real sauropod. They also have brachiosaur-like bodies appropriate for a giant macronarian, and osteoderms found preserved on titanosaur fossils.
Ceratopsians
- Amazing Technicolor Wildlife: While even to this day we don't know for sure what dinosaurs looked like color-wise, it's rather unlikely that some of them were neon green.
- Animal Stampede: After the Night Feeder attacks them, they stampede through the forest in panic.
- Half the Man He Used to Be: One of them gets sliced in half snout to tail by the Night Feeder.
- Informed Species: While the animatic calls them Triceratops, they look a lot more like Diabloceratops (though still with Triceratops's nose horn and forward-facing brow horns) or possibly Xenoceratops.
- Temper-Ceratops: Downplayed. One of them starts acting up when it senses it's being stalked, until it gets a good look at its stalker. The herd as a whole later attempts to mount a defense against the Night Feeder, but only once fleeing proves not to be an option. Not that it does them any good.
- The Worf Effect: An entire herd of large, powerful dinosaurs who band together for defense. And the Night Feeder kills them all, showing that simply standing your ground won't be enough to stop it.
Small Theropod
- Butt-Monkey: Downplayed; while nothing bad happens to it (unless it is, indeed, the Night Feeder itself), he only appears in the episode to fruitlessly try to catch a fly, then gets scared shitless by a very annoyed Fang who roars at the poor thing.
- Our Werebeasts Are Different: Vaguely implied to be the natural daylight form of the Night Feeder, though never confirmed.
Anzu
- All There in the Manual: Its genus was revealed by David Krentz.
- Goofy Feathered Dinosaur: It is a prey animal that acts like a chicken, makes comical flamingo-like honking vocalizations, and is quickly killed. Unlike many examples of this trope, however, it's actually feathered in a realistic and accurate fashion with the "goofy" aspect coming mainly from its behaviour.
- Hope Spot: It avoids both Fang and Spear trying to hunt it and gets away safely across the river... just to be shot be Mira.
- One-Hit Kill: Mira kills it with a single shot from her bow and arrow.
- Red Shirt: It is killed by Mira with an arrow, then cooked and eaten by the heroes.
- Shown Their Work: It is the first feathered non-avian dinosaur in the show, and accurately feathered to boot.
Giant birds
- Bizarre Sexual Dimorphism: What are presumed to be males have bright red feathers on their heads in various different arrangements. Completely bald birds are seen in the nest and are presumably female.
- Brutal Bird of Prey: They are monstrous avians that resemble condors and are quite dangerous.
- Giant Flyer: They're about the same size as Fang and are very capable fliers
- Mix-and-Match Critters: They closely resemble teratorns (or rather, outdated depictions of them as vulture-like) but have teeth like Mesozoic birds.
- Non-Malicious Monster: They're not actually interested in fighting the trio but are being forced to by the Chieftain and Eldar. Once they're released, they quickly fly away.
- Toothy Bird: They possess numerous teeth in otherwise typical beaks. Perhaps a small bit of unintended accuracy as several extinct avian dinosaurs possess at least partial beaks while retaining functional teeth.
- Vile Vulture: Downplayed. They resemble giant toothed vultures, but are not particularly aggressive and are content with leaving the trio alone once they are released.
Reptiles
Giant Crocodile (Deinosuchus)
- Animals Not to Scale: The real Deinosuchus was very big, around 10 meters long, but this one is even bigger.
- Establishing Series Moment: This giant croc is the first creature encountered in the series, attacking Spear as he hunts fish. In the brief moment of its presence, it establishes the setting, the creatures living in this world, and the daily struggle to simply survive.
- Never Smile at a Crocodile: A hungry predator that lunges at Spear as he is fishing.
- One-Shot Character: Leaves almost as sudden as it arrives.
Pterosaur
- Establishing Series Moment: A secondary one. The pterosaur shows that the Deinosuchus moment was no fluke and that Spear is nowhere near the top of the food chain. The world is full of monsters he'd prefer not to fight, even if it means going hungry. And these monsters have things that they're afraid of, too.
- Giant Flyer: This pterosaur towers over Spear.
- Mix-and-Match Critters: It has the long neck and body proportions of Quetzalcoatlus, a bony crest on the back of its head similar to Pteranodon, and a toothed bill and fleshy crest-like Pterodactylus.
- One-Shot Character: It lands, smells Spear's fish, roars at something, and then leaves the show for good.
- Shown Their Work: For all its inaccuracies, at least it is quadrupedal, has non-columnar forelimbs, and hunts terrestrially like a large azhdarchid. It is also one of the few pterosaurs in fiction to be depicted with a fleshy crest, which we know some pterosaurs to have possessed in real life.
- Terror-dactyl: It appears to be a gigantic, fierce predator that Spear hides from rather than trying to fight it. It looks hairless, has five fingers on its wings (four claws plus the long membrane-holding finger), and is a mix-match of different pterodactyloids. At least it walks (mostly) on four limbs and does not grasp anything with its feet.
Giant Snakes
- Animals Not to Scale: While the largest one is about the right length for a Titanoboa, it's also much thicker than that species was.
- The Great Serpent: At least a few of them are quite gigantic in size.
- Snakes Are Sinister: They are gigantic snakes and hostile predators.
- Somewhere, a Herpetologist Is Crying: They resemble pythons or boas, but have fangs like venomous snakes (a common error in constrictor snakes in cartoons). And yet, they seem to be non-venomous just like pythons and boas.
Liopleurodon
- Impaled with Extreme Prejudice: Spear kills it by driving his spear through its skull.
- Informed Species: Zig-zagged. While David Krentz confirms it to be a Liopleurodon, the animatic calls it a Tylosaurus.
- Sea Monster: It is a monstrous sea creature with gaping jaws and is capable of roaring.
- Shown Their Work: It is correctly sized at around 7 meters in length, as opposed to the 25-meter-long scale popularized by Walking with Dinosaurs.
Archelon
- Animals Not to Scale: Downplayed, there are a few shots where next to Spear it looks positively gargantuan, but it usually appears only slightly oversized (it bears keeping in mind, of course, that Archelon really was a downright massive turtle either way).
- Artistic License – Paleontology: Looks more like like an oversized modern Chelonoidea turtle than an actual Archelon. Additionally, it retains flippers claws, while protostegids like Archelon were much more streamlined.
- Attack Its Weak Point: Spear quickly realizes that the only way to kill it is to attack its throat, but fails at doing so. Fang does it with a single bite to the neck.
- Graceful in Their Element: Dangerously nimble and durable underwater, it gets killed as soon as it faces Fang above the surface.
- Sea Monster: While not outright aggressive, it still is a huge marine reptile and quite dangerous when provoked.
- Sturdy and Steady Turtles: Subverted. While it's hard to kill and does not seem willing to give up a fight, it's also surprisingly quick.
Tropeognathus
- Artistic License – Paleontology: They're leagues better than the other pterosaurs seen up to this point, but they still have broad, low-aspect ratio wings more typical of inland pterosaurs, unlike the long wings of the real animal. They also appear to retain the stereotypical bird-like talons of most fictional pterosaurs (though they never grab anything with them this time).
- Giant Flyer: They're roughly the same size as the giant bats - though unlike them, this species really WAS that big.
- Shown Their Work: They possess pycnofibres and hunt fish by diving into the water.
Mammals
Horned Deer (Syndyoceras)
- Animals Not to Scale: The Syndyoceras in the flashback scene of "A Cold Death" is around the size of a large moose. In real life it was as big as a medium-sized deer or antelope, weighing about 60 kg.
- Gentle Giant: It's an enormous herbivore that shows no sign of aggression, instead fleeing for its life as Spear and his son try to kill it.
- One-Hit Kill: Killed from a single, well-aimed spear strike.
Mammoths
- Animals Not to Scale: Real-life woolly mammoths were slightly smaller than African elephants. These beasts, especially their matriarch, are at least twice as big, towering over Fang, a Tyrannosaurus.
- Anti-Villain: The mammoths attack Spear and Fang remorselessly, but it's only because they ate one of their own and took away its tusk. Once Spear gives it to them, they retreat to ceremonial grounds.
- Cruel Elephant: Subverted. They're aggressive and try to kill Spear and Fang, but only because they took the tusk of the elderly mammoth with them. Once Spear gives them the tusk, they stop attacking.
- Due to the Dead: They hold a funeral ceremony for the elderly mammoth, swinging side to side while humming and touching his tusk with their trunks. While it's not known if actual mammoths did this, modern elephants certainly do.
- Elephant Graveyard: They take the tusk of their fallen herd-mate to one of these, holding some kind of funeral ceremony for him.
- Eye Scream: Subverted. Spear uses a rock to seemingly smash the eye of the elderly mammoth into a bloody pulp, but the eye itself remains intact.
- Genius Bruiser: As expected from a herd of elephants. They are giants who can smash rock with their heads, are intelligent enough to track enemies and take advantage of their numbers.
- Handicapped Badass: The old mammoth who got lost from the herd was old, clearly sick, and missing a tusk. It still put an impressive fight.
- Honorable Elephant: The mammoths are presented as particularly intelligent prehistoric beasts who mourn for their dead.
- Implacable Man: When the mammoth herd wants to avenge their dead, they will pursue the object of their vengance and they walk off everything Fang and Spear throw at them.
- It Can Think: The fact that they can comprehend vengeance and give Due to the Dead shows that they are not by any means stupid.
- Large and in Charge: The mammoths are all giants, but the matriarch of the herd is noticeably bigger than the rest.
- Lightning Bruiser: They aren't as fast as Spear and Fang, but they are by no means slow despite their bulk.
- Mammoths Mean Ice Age: Not exactly Ice Age, but they are shown living in a snowy environment.
- Reasonable Authority Figure: The matriarch cares for the rest of her herd, and is convinced by Spear to allow him and Fang to live.
- Shown Their Work: In real life, Elephants will hold funeral ceremonies for a deceased member of the herd much like the ones the mammoths hold in the show. The caressing of the dead elephant's remains and swaying are all real elephant behaviours.
- Super-Toughness: The elderly mammoth was resilient despite her age. The younger ones can take getting bitten by Fang and it does no lasting damage to them.
Saber-toothed Wolves
- Mix-and-Match Critters: They look like wolves with Smilodon-like teeth.
- Oh, Crap!: They quickly scatter when the mammoth herd approaches them.
- One-Shot Character: They scavenge on the corpse of the mammoth, then retreat when the other mammoths return.
- Reused Character Design: Without the large jutting fangs, their white fur, cyan colored pupils, and black sclera, they look downright identical to the lone wolf from Season 5 of Samurai Jack. It's unclear if this design was considered to be intentional or not but the resemblance is without a doubt uncanny.
- Savage Wolves: Subverted. Despite their menacing saber-like canines, they flee at the approach of the mammoth herd.
Giant Bats
- Airborne Mooks: The first flying enemies that Spear and Fang have to face.
- Amazing Technicolor Wildlife: They have blood-red fur.
- Animals Not to Scale: They are far bigger than any real-life bat species, close in size to the largest pterosaurs.
- Artistic License – Biology: Their rear legs bend the wrong way for bats. On real bats, the legs face backwards, so the knees bend forward and the toes face towards the tail, and they walk plantigrade, with their heels on the ground. These giant bats have forward-facing, digitigrade legs, making them look more like a wyvern or dragon.
- Avenging the Villain: After the Giant Spider is killed, the bats sought to avenge its death.
- Bad Moon Rising: They attack during a blood moon.
- Bat Out of Hell: They are blood-red, gigantic, and incredibly horrifying.
- Berserk Button: When the giant spider is dead, they lose it and hunt down Fang and Spear.
- Big Red Devil: While they are presumably naturally evolved animals and not supernatural, their humanoid anatomy, skull-like faces and bright red skin are clearly meant to make them evoke classical demon imagery.
- Captain Ersatz: They resemble the vampiric bat-like humanoids from Hotel Transylvania 2 (also directed by Genndy Tartakovsky), except colored red and unable to talk.
- Decapitated Army: Inverted. The death of the Giant Spider only causes them the entire flock to relentlessly hunt down Spear and Fang.
- The Dreaded: They are the reason the local primitive humanoids always hide in the dark. Even the raptors flee when they know when the bats are approaching.
- Establishing Character Moment: When one of the primitive men breaks his leg, another decided to help him out. He gets swooped up in an instant by the giant bats.
- Fragile Speedster: The bats can be killed easily, but they are fast. So much so that when they are initially picking off the primitive men, the audience isn't even able to see what they look like.
- Giant Flyer: They can fly and are larger than Fang.
- Mix-and-Match Critters: Look closely, and you might notice some simian (or human-like) features, such as a short snout, enlarged craniums, the aforementioned forward-bending knees, and their shrieks sound rather monkey-like in some scenes. Appropriately, the animatic calls them "man-bats".
- Zerg Rush: While significantly larger than Fang, these creatures prefer to use numbers over size to overwhelm their foes.
Wild Dogs
- Artistic License – Biology: Despite the fact that they're identified as wild dogs, they also somewhat resemble hyenas (even using the spotted hyena's famous laugh occasionally). Canines and hyenas are not closely related to each other. They do, however, resemble borophagines, extinct canids with hyena-like bone-crushing jaws.
- Boring, but Practical: A villainous variety. Chronologically, they enter the story after Spear and Fang have done battle against Ape Men powered by a mystical super serum. The wild dogs, in contrast, are more your typical garden-variety scavengers... but they are still a huge problem for a near-dead tyrannosaur, and Spear rightly regards them as such.
- Bullying a Dragon: Subverted. Though they have numbers on their side, it's clear that under ordinary circumstances the dogs wouldn't go anywhere near a healthy, adult tyrannosaur but with Fang severely injured and barely able to move, the dogs are emboldened enough to decide to try and make a meal out of her. It's only due to the constant vigilance of Spear that they're kept at bay. Once Fang finally recovers it goes as well for the dogs as you'd expect and their remaining members promptly decide to cut their losses and flee.
- Heinous Hyena: They have the "giggle" of spotted hyenas.
- Hell Is That Noise:
- Their silent, ominous vigil over Spear in the first half of the episode is always accompanied by a horrible, blaring three-note theme.
- Their giggling also counts... especially in the moments where you can't see the dogs themselves.
- Mix-and-Match Critters: They share traits with both African wild dogs and hyenas.
- Red Eyes, Take Warning: Their most prominent physical characteristic, seen as they watch Spear from the gloom beyond his campfire.
- Savage Wolves: Not wolves per se, but they play the part well enough.
- Super-Persistent Predator: They stalk Spear and Fang nonstop for days, waiting for an opportunity to strike. Justified, as this is completely normal behavior for predators hunting an injured prey item, especially in the case of a large animal that they would never be able to bring down in a healthy state.
- Zerg Rush: There are hundreds of them.
Smilodon
- Artistic License – Paleontology:
- It has a head like a modern big cat rather than a true machairodont.
- A couple of them were seen biting down on Spear's father without securing him with their paws first, with one of them even sinking its sabers into his arm and ripping it off. In real life, this would cause their fragile sabers to be broken off.
- Back for the Finale: A pack of them appear in the opening of the final episode of the second season, in a flashback detailing the death of Spear's father.
- Cats Are Mean: The pack from Spear's past was extremely vicious and relentless in attacking the Neanderthals.
- Ludicrous Gibs: The Night Feeder shreds the big cat into pieces and leaves the corpse behind uneaten.
- Panthera Awesome: A large saber-toothed cat.
- Shown Their Work: Its body proportions are very accurate, with long forelimbs, shorter hind legs and a hunched back similar to a hyena, as well as a short bobcat-like tail.
- The Worf Effect: Shows up to demonstrate that the Night Feeder is dangerous enough to kill other apex predators without a fight.
Whale pod
- Bit Character: They're only briefly seen at night while Spear and Fang are traveling the ocean, and they leave as soon as they arrive.
- Gentle Giant: Unlike the predatory pterosaurs and the megalodon, and the turtle that fights back in self-defense, these enormous sea creatures peacefully swim by without doing any harm to Spear, Fang or their raft.
Arsinoitherium
- Artistic License – Paleontology: It's depicted with a short, tapir-like trunk. This used to be a somewhat fashionable feature in reconstructions of the genus based on the fact that its order (Embrithopoda) was once believed to be related to elephants, but has subsequently been questioned following renewed examination of its phylogenetic position and doubts that its snout structure would have been capable of supporting a trunk.
- Monster Munch: Its only role in the story is becoming the first mutual prey of Fang and Red.
- Oh, Crap!: Its expression when it realizes both Fang and Red are going to attack it at the same time.
Volaticotherium
- Not Quite Flight: It's shown gliding, yet it gains altitude through utterly unclear means, covering much larger distances than any mammalian glider.
- Ridiculously Cute Critter: They are a small, flying squirrel-like mammal with big rounded eyes, making it surprisingly cute.
Megaloceros
- The Marvelous Deer: The males sport an impressive set of antlers.
Long-horned Bison
- Herbivores Are Friendly: A whole herd of them is not aggressive towards Spear and continues to graze in the plains.
Cave Bears
- Animals Not to Scale: Real cave bears were comparable in size to the largest living bears. These ones are almost as big as Fang, a Tyrannosaurus.
- Bears Are Bad News: These bears are just as huge and as vicious as Fang.
- Horse of a Different Color: They serve as the mounts of the Vikings.
Elephants
- Animals Not to Scale: They are the same size as the mammoths in Season 1, larger not only than modern elephants but even the extinct giant Palaeoloxodon namadicus.
- Cruel Elephant: Subverted, they and their masters are not true antagonists, they are simply defending themselves from the Egyptian queens’s invading army, unfortunately they are obstacles that Spear and Fang are forced to kill by the queen because she is holding Fang’s eggs and Mira captive.
- Expy: Based on their size, appearance, and the general circumstances of their encounter by the protagonists, they may be a reference to the Mumakil/Oliphaunts from The Lord of the Rings.
- War Elephants: The Babylonian army uses them as mounts when defending their walls against the Egyptians.
The Egyptian Queen's Leopard
As a cub.
As an adult.
- Attack Animal: When Spear breaks into the Queen's throne room, the leopard attacks him, only to be quickly tossed away by the caveman.
- Cute Kitten: As a cub, it looks absolutely adorable.
- Humanlike Animal Aging: Inverted, it grows into an adult leopard in a few months (a shorter time than it takes for Fang's eggs to hatch) rather than 2-3 years.
- No-Sell: The leopard pounces on Spear, but the cavemen simply tosses it aside. Compared to the animals Spear usually fights, a leopard is a mere kitten.
- Right-Hand Cat: First introduced as a cub, being the pet of the Babylonian king. After the King is killed by the Egyptians, the Queen keeps the cub and raises it.
- Uncertain Doom: It isn't seen again after Spear tosses it aside to get at its owner. While it's possible it was killed by this, it could also have survived.
Fish
Megalodon
- Always a Bigger Fish: A literal one. The megalodon devours the Tropeognathus that is harassing Fang and Spear.
- Animals Not to Scale: Far larger than a real life megalodon, its teeth are longer than Spear's legs. Real megalodon is estimated to be 15 to 20 meters (47 to 66 feet) long, whereas this beast seems to be at least 50 meters.
- Eye Scream: Spear manages to chase it away by driving a tree trunk trough its eye.
- Kaiju: It appears to be at least twice the size of a real megalodon, putting it squarely within this category.
- More Teeth than the Osmond Family: Obviously, as it's a giant prehistoric shark.
- Sea Monster: A very hostile sea beast that attempts to devour Spear and Fang.
- Swallowed Whole: Tries it with Fang, almost succeeds with Spear.
- Threatening Shark: The biggest threat Spear and Fang face during their maritime journey.
Placoderm
- Mix-and-Match Critters: It looks like an average arthrodire placoderm (similar but clearly much smaller than Dunkleosteus) but has a body shape resembling the Mahi Mahi.
- Monster Munch: Like the flying fish they eat, the placoderms only serve as food for Fang and Spear.
- Speculative Biology: They bear a notable resemblence to Mahi Mahi, implying that in this world the species evolved from arthrodire placoderm fish instead of ray-finned fish.
Flying fish
- Monster Munch: They're only there to serve as food for Fang, Spear, the placoderms and the pterosaurs.
Other/Supernatural Creatures
Giant Spider
- Artistic License – Biology: Besides its size (which completely defies the Square-Cube Law), it has a few odd anatomical features, including a toothy lower jaw under its chelicerae, and a silk gland inside its mouth (rather than the end of its abdomen).
- Evil Tower of Ominousness: Its lair is on top of a large stone spire, giving this impression.
- Giant Spider: Emphasis on giant. It's larger than a sauropod.
- Impaled with Extreme Prejudice: Spear kills it by ramming a Triceratops horn into its head.
- Interspecies Friendship: Implied - while it does eat the bats' kills, the fact they try to avenge it implies this is an entirely voluntary agreement on their part. The animatic implies that they feed on its leftovers.
- It's Personal: It does not like Fang managing to rip a chunk of its leg out, and subjects her to Metronomic Man Mashing afterwards. It even disregards Spear after he tries to batter another of its legs in with a rock to distract it and slaps him against the wall to focus on beating Fang some more, which just gives him the opportunity to impale it through the head with a Triceratops horn he salvaged from it's meals.
- Mook Commander: Apparently it controls the bats, as they handed Spear over to it instead of eating him themselves.
- Nice Job Fixing It, Villain: It outright ignored Spear when he tries to batter one of its legs in with a rock to remain focused on dealing with Fang, giving him the opportunity to ambush it again with a better weapon whilst it's distracted.
The Plague of Madness
A pathogen/curse that drives its victims into a murderous rage and leaves them looking like the walking dead.
A hadrosaur (possibly Parasaurolophus) infected with the Plague. The dinosaur dies after getting thrown into a tree, but not before biting the Argentinosaurus that killed it, turning the sauropod into the Plague's next victim.
Also called the Plague Monster or the Mad Sauropod, the Infected Argentinosaurus is the next victim of the Plague of Madness after the Infected Hadrosaur bit it. The former peaceful dinosaur goes on a brutal rampage and chases Spear and Fang.
- Enemy to All Living Things: Not only do its carriers try to kill everything in sight, anything even touched by the Plague seems instinctively avoided by animals. The carcasses of the sauropod herd killed by their infected member don't even have any flies around them, which in normal circumstances would quickly become attracted to any carcass in droves.
- Fate Worse than Death: This is what basically happens to any living being who's fallen victim to suffering this mysterious pathogen. Prolonged experience with this induced plague will eventually cause any organism to do nothing but suffer nasty coughing, wheezing, dehydration, brutal regurgitation of one's very own blood, (and that's before the disease completely takes over its host), intensive urges to kill any living thing that moves, violently thrashing around at others with no sense of intentional direction, yelling out in pure genuine agony, heightened aggression, inflicting their own fatal injuries, immense recklessness into disastrous areas without even thinking, and even dissolving various organs and muscles within the host's body. The previous creature that went through this disease was the hadrosaur, as the creature couldn't even attack its own intended target properly until it finally managed to approach the ankle of the unaware Argentinosaurus by biting into it and transferring the disease into the very next unfortunate victim.
- Green Is Gross: Arguably the most distinctive side-effect of this unknown disease, which changes the victim's original color into a shade of yellow-green as their flesh decays. Said flesh also makes some really disgusting squelching and bubbling sounds for no apparent reason.
- Hoist by His Own Petard: The Plague’s continued existence relies on its infectees surviving to become moving hosts that can continue to spread it, but by infecting the Sauropod, it effectively doomed itself by infecting something too strong to NOT kill everything it attacks.
- Maybe Magic, Maybe Mundane: It's unknown as to what exactly the Plague is or where it came from. All we know is that it drives whoever it infects to become a rampaging horror, it rots their body far faster than would happen naturally, it can seemingly keep its victims alive well beyond the point where they should be dead, and it makes its carriers and their carriers' victims avoided by things that would normally eat them. It is utterly unnatural and is given no explanation as to how or why it exists.
- Meaningful Name: Going by the name, the Plague of Madness drives anyone unlucky to contract it with an insane desire to kill any living creature they see while turning them into a zombie-like being.
- Nothing Is Scarier: It is at no point explained or given an origin. It just exists.
- Our Zombies Are Different:
- It turns its host into a Plague Zombie and renders them utterly Ax-Crazy. It's implied the virus' victims are Technically Living Zombies who can run very fast and be killed by a broken spine, but they're still far more difficult to put down than they would be in their uninfected state, and the Plague causes the infected's flesh to rapidly turn green and putrefy, exposing protrusions in the bones, making the flesh behave as if it's already dead whilst keeping the host up and running.
- Its victims seem to become even faster, to the point that something as slow and heavy as the world's largest sauropod can suddenly keep pace with a paleolithic ninja like Spear.
- Interestingly, all its victims seen so far have been non-avian dinosaurs, so it might not be capable of infecting humans.
- Plague Zombie: It spreads from host to host via bites, which the hosts it turns Ax-Crazy are particularly inclined toward even if they're herbivores. Note that while the Plague drives distinctly herbivorous hosts to likely attempt to bite the flesh of their victims, the infected Argentinosaurus didn't eat its fellow sauropods when they were dead, and its massacre implies the infected will settle for brutally killing their victims through any means so long as they're dead.
- Red Eyes, Take Warning: Downplayed; both of the seen victims have these, but the Argentinosaurus and presumably the hadrosaur have these naturally. It's when the yellow veins appear all over said eyes that the trope is played straight.
- Tainted Veins: The final sign the Plague has fully taken hold of a creature is when their eyes become covered in yellow veins. Notably, right before the hadrosaur dies the veins disappear, as if it were being released from control, and the sauropod has them appear right before it goes on its killing rampage of its whole herd.
- Technically-Living Zombie: The Plague seems only able to take effect on animals that are still living, lacking the ability to re-animate corpses in the usual zombie fashion. As such its victims aren't strictly speaking dead, even if they very much look that way.
- Undeathly Pallor: Notable for how fast this sets in; it legitimately takes less than two minutes for the infected Sauropod to start look like a walking corpse.
- The Virus: Naturally.
Infected Hadrosaur
- Blood from the Mouth: In its final moments upon death after getting kicked into a tree, blood oozes and spills out of its maw, signifying that the animal has been finally put out of its misery from this ungodly disease.
- Body Horror: The Plague has rendered it a mutated abomination, with its eyes blood-red and changed to a state of madness, pulsating sores all over its body, a sickly green complexion, and large chunks of flesh missing, with the rest of it rotting and melting off. It gets this even worse than its victim, likely due to having been infected for longer.
- Killer Rabbit: While looking hideous, it is approximately around Fang's size, which is tiny compared to the sauropods. The sauropod is more curious than scared of it, which proves to be a fatal mistake.
- Mind-Control Eyes: Right before it gives up the ghost, the Tainted Veins in its eyes vanish. Its victim in turn gets these right before it goes on its killing rampage.
- Nothing Is Scarier: We never learn how the hadrosaur was infected or what caused it.
- Raising the Steaks: A zombie dinosaur.
- Red Eyes, Take Warning: Its blood-red eyes indicate that it has gone completely mad.
- Small Role, Big Impact: It charges into the herd of sauropods and bites one of them, transmitting its horrifying disease to the sauropod before being effortlessly killed by its victim.
- Undeathly Pallor: Though it was actually still barely alive, its diseased and rotting condition made its complexion turn a sickly green.
- Unwitting Instigator of Doom: The Hadrosaur is clearly in the extremely late stages of the infection, with its brain being almost completely decayed, and is barely aware of what's going on around it, stumbling around in a haze before bumping into the Sauropod and transmitting the disease via reactionary bite.
Infected Argentinosaurus
- Alas, Poor Villain: Its death is a somber moment as it burns to ash while failing to escape the lava, Spear and Fang feeling sorry for the creature.
- And I Must Scream: It's vaguely implied that the Plague is most likely controlling the sauropod, and keeping it alive even if its body was shredded after aggressively squeezing out of the ravine and burning in lava.
- An Arm and a Leg: When the crazed beast falls into lava for the third and final time, before getting entirely scorched to death, the very first thing that goes is the burning flesh of its forelegs that incinerate almost in a Stripped to the Bone manner. This is what keeps it from getting out again, finally ending its miserable existence.
- Ax-Crazy: The Plague turned it into a raging monster that attacks everything in sight, driving to murder its own herd, destroy their nests, and chase Fang and Spear for the entire episode.
- Bloodbath Villain Origin: Once the Plague takes full control, its first order of business is killing its entire herd in a mad and bloody rage: stomping eggs into paste, ripping out throats, hitting with enough force to break bone and punch through flesh, and just plain slamming its victims into the environment with enough force to fatally impale them on it.
- Blood from the Mouth: Its mouth and nostrils are constantly dripping blood and mucus, in fact, it projectile vomits a large amount of blood before going into its feral state.
- Body Horror: The Plague has rendered the poor beast a mutated abomination, with its eyes blood-red and changed to a state of madness, pulsating sores all over its body, a sickly green complexion, and large chunks of flesh missing, with the rest of it rotting and melting off. By the time it tears its flesh open to free itself from the narrow ravine, a shot of its now-exposed ribcage bones shows there's no internal organs left behind them, just a black void. It becomes no less horrifying after it falls into lava the first time, getting cooked until its complexion turns from green into reddish, horribly-burnt flesh. And when it falls into the lava a second time, what's left of its leg burns and melts off the bone.
- Determinator: The infected Argentinosaurus slaughters its entire herd before setting its sights on Spear and Fang. The former herbivore goes through an absurd amount of punishment just to kill our two heroes; from falling down a ravine, tearing chunks out of its body when it gets stuck in said ravine, and getting dunked in lava twice, this beast won't stop. In the Argentinosaurus' defense, it's not going on a rampage because it wants to; it was driven mad by a plague/curse that made it go homicidal.
- The Dreaded: Fang and Spear are terrified of this thing. The first encounter leaves Spear with nightmares of it killing both of them. Fang doesn't even want to leave the safety of the cave even when it appears to be dead.
- Enemy Rising Behind: It makes its presence first known to Spear and Fang when it slowly gets up from behind both of them. It does this a second time when the pair try to sneak away after it fell into a ravine.
- Expy: Of Cujo. Both start out as a Gentle Giant before being infected by a madness-inducing virus, and end up being a menace because of their great size. Both also take a lot of damage before dying.
- Face Framed in Shadow: The second Spear and Fang take notice of the sauropod's existence that's standing right behind them, the screen pans up from its legs all the way up to its long neck and head that's mainly covered in an eerie and ominous shadowed appearance, just from how large it is, while also being accompanied with Glowing Eyes of Doom.
- Giant Equals Invincible: Fang and Spear don't even bother trying to fight it, they know given its size they stand no chance even if it wasn't a crazed infected beast. In its relentless pursuit it does more damage to its own body than they ever could. It only dies when falls into a Lava Pit.
- Green and Mean: Inverted. Big time. The creature had no intention to be blood-thirsty or insatiably aggressive (let alone evil). The Plague itself is to blame for rendering the sauropod's mind into a frantic and rabid beast whose actions weren't entirely his own. Before the infection could fully take over, all it could do was to suffer unspeakable amounts of pain.
- Hoist by His Own Petard: Chases Fang and Spear onto a layer of rock over lava. The rock ground is already cracking from Fang's weight, which quickly gives way to the monster's bulk and dunking it into the lava, eventually burning it to ash.
- Horrifying the Horror: When this... thing makes Spear, a hardened prehistoric man, and Fang, a 'Tyrannosaurus rex', run for their lives, and in clear terror, then that's an achievement unto itself.
- Implacable Man: It never stops once it sees something to attack. After falling into a ravine, it got back up. When caught in the narrow exit of the ravine, it pushed so hard it tore apart its own body. Even falling into lava couldn't kill it on its own; the first time it was able to climb out and resume the chase, and only the lava burning off its forelegs keep it from escaping the second time.
- Instant Illness: It starts showing signs of infection mere seconds after it was bitten by the infected hadrosaur. This is the first sign that the Plague of Madness is not even remotely a normal virus. Of course, the Smash Cut to the beast's "infected" state might have been meant to represent a considerably longer period of time, perhaps a few hours, or a day or two.
- The Juggernaut: This thing will not stop. Trees in its path get flattened. It will literally tear itself to shreds in order to get to the nearest live body and its massive size means nothing Spear or Fang could throw at it would slow it down. Even after falling into lava, it still keeps going. It's only done in after it lands into lava a second time and its forelegs burning off prevent it from escaping again.
- Kaiju: What was originally a placid sauropod after getting infected is turned into a zombie-like monster with an unnatural determination to kill any living thing in its vicinity and an almost supernatural speed for a creature its size.
- Lightning Bruiser: It is FAR faster than any dinosaur its size should be (easily catching up to a fleeing Sauropod), and survives getting submerged in lava the first time. It even jumps, which is even more impossible for a sauropod than just running. Whatever the Plague is, it made it far more agile than it should be. That being said...
- Logical Weakness: Its massive size and weight made it get its neck briefly stuck in a hollowed tree, fall into a ravine, get stuck in the narrow exit of said ravine, and ultimately does it in when the volcanic rock it jumps on gives way and dunks it into a Lava Pit.
- A Molten Date with Death: It takes falling in molten lava twice to put the wretched thing out of its misery.
- No Body Left Behind: All that's left of it after it burns up in a lava lake is ashes that scatter on the wind.
- Not Quite Dead:
- Upon falling into a ravine while trying to go after Spear and Fang at one point it slams its head into the side of the rock wall, causing blood to briefly spray out of its cranium and seems to be kaput. After Spear and Fang wake up the sauropod looked immobile almost as if it actually died from the "concussion" earlier. They attempt to sneak past and quietly walk away... until it started to move again.
- During another chase at a Lava Pit the infected sauropod sinks into the magma below which gives Spear and Fang a dosage of hope thinking that it's finally gone... only for the unkillable abomination to burst out, screaming in intense pain with burnt blood-red cooked flesh, still wanting to go after them to no end.
- Raising the Steaks: A zombie dinosaur.
- Red Eyes, Take Warning: It's shown succumbing to the final stage of infection when the blood vessels in its eyes burst.
- Run or Die: The only thing Spear and Fang can do against it is to run, due to how fast and powerful it is.
- Self-Disposing Villain: Pursuing Spear and Fang gave this creature horrendous luck as it kept putting itself in lethal harm the more it chased them. It had its neck stuck underneath a tree, slid down a hill and landed on its back and left itself unconscious after hitting its head near a wall. It got even worse when it was momentarily stuck in a crevice, where the beast was frantically struggling and squeezing to get out until it freed itself by tearing the flesh of its own body. Either this infected sauropod was that desperate to get them, or creatures infected with this plague tend to put themselves in life-threatening moments to catch victims.
- Super-Persistent Predator: Once it gets on Spear and Fang's trail, it refuses to give up until they're both dead, or it dies. An odd example, in that it's not technically a predator.
- Technically-Living Zombie: While the disease certainly gives it many of the physical and behavioral traits associated with zombies, it doesn't actually appear to be undead, although it does appear to enter a dormant state when there's nothing around to kill.
- Tragic Monster: It was originally a peaceful sauropod until it was bitten by an infected hadrosaur, after which it slaughtered its entire herd.
- Undeathly Pallor: Though it's actually still alive, its diseased and rotting condition changes its healthy blue-green complexion turn a sickly yellow-green.
- Woobie, Destroyer of Worlds: It was originally a normal Argentinosaurus until it got infected by the Hadrosaur. The dinosaur's noises after the infection took over were it basically screaming and roaring in agony as it kills anything that moves as the condition got worse and kept screaming until it literally couldn't anymore when it got burned by lava.
- The Worf Effect: When was the last time you saw a goddamn Tyrannosaurus flee in actual, clear terror of something?
The Night Feeder
A mysterious, nocturnal predator that hunts in some dark woods that Spear and Fang travel through. Its speed and strength are unmatched, as is its sadism.
- Absurdly Sharp Claws: It has huge, therizinosaur-like claws which it uses to cut through animals and trees like they're made of paper. At one point it even manages to perfectly bisect a ceratopsian, snout-to-tail, as though prepping it for an anatomical diagram.
- Animalistic Abomination: Resembles a theropod, but vaguely implied to be something other than a mundane dinosaur (especially given the reactions other dinosaurs have to its presence, which seem to go beyond what would be merited by simple fear of a normal predator).
- Asshole Victim: Unlike the Plague Monster, the Night Feeder has no redeeming qualities whatsoever which is why Spear and Fang stare at its death in Tranquil Fury.
- Covered in Gunge: Appears to be dripping in a black tar-like substance which has a foul odor, and presumably gives it stealth in the dark. It's also highly flammable as a result.
- Cruel and Unusual Death: After Spear hits it with a flaming spear, it spends several seconds writhing around in agony as it’s burned from the inside out.
- The Dreaded: The dinosaurs seem to be instinctively terrified of the Night Feeder. Even Fang turns and initially bolts for the trees upon first smelling it, passing up a perfectly good kill.
- Dirty Coward: It seems to intentionally terrify its victims before going in for the kill but when confronted with fire it immediately starts fleeing.
- Enemy to All Living Things: It doesn't kill to survive. It kills because it can, and it kills everything it finds, littering the forest with shredded carcasses.
- Evil Smells Bad: It has a very foul odor, which is the only way anyone can sense its presence.
- Foil: To the Plague Monster. They're both fast monsters and are the antagonists of their respective episodes that has the intent to kill everything in their path right until they encounter our protagonists. They also burn to their deaths at the end of their episodes. The key differences is that the Plague Monster was an infected Argentinosaurus driven by madness by a viral/supernatural infection, to the point that despite unable to be able to fight back against it, Spear and Fang pities the poor dinosaur as it burns to ashes. The Night Feeder is a sadistic monster that kills anything that moves, which Spear and Fang are capable of fighting back against, and ultimately set it on fire, staring at it with pure contempt as the beast meets its end. To further the contrast, the Plague Monster was a peaceful herbivore, the Night Feeder is a carnivore.
- Glass Cannon: Incredibly fast and powerful, capable of effortlessly toppling several redwood trees and slicing through an entire herd of ceratopsids, but is killed in one hit by a flaming spear shot.
- Hate Sink: A sadistic monster that enjoys killing innocent creatures just for the sake of it, not even eating the carcasses of its victims. The Night Feeder is basically a prehistoric serial killer, and as a result it's rather hard to feel sorry for it when it finally dies at the hands of our protagonists.
- Hell Is That Noise: Emits a warbling, high-pitched shriek that's far from pleasant to listen to.
- Home Field Advantage: It hunts ravenously at night where it tends to blend within the darkness where any "trespasser" is unable to make out what the beast even looks like and goes in for the kill. When Spear and Fang are in the middle of a foggy location, it can also be seen as an accidental death sentence where the Night Feeder seems to have depth perception of where its enemies are located.
- The Hunter Becomes the Hunted: It makes the mistake of going after Spear and Fang, and almost succeeds, but they accidentally discover its weakness to light and it's forced to flee. The next night, the Night Feeder is the one running for its life from, and is ultimately killed by, what it intended to be its prey.
- It Can Think: It has at least enough intelligence to be deliberately sadistic rather than simply killing for survival.
- Innate Night Vision: Another possible ability the Night Feeder might actually have, as it was able to perfectly see victims from afar without having the need to capture the scent of its prey.
- Kill It with Fire: How it meets its end, Spear lights his weapon on fire and catches it off guard, impaling it and having it burn from the inside out until its nothing but ashes.
- Lightning Bruiser: It does not slow down at all once it gets going, to the point it seems almost supernatural. While it does so, it has enough strength and momentum to reduce most animals to Ludicrous Gibs and topple thick pine trees.
- Logical Weakness: It appears to be covered in a foul-smelling oil- or tar-like substance, which gives it stealth in the darkness. This however also makes it highly flammable.
- Made of Evil: Implied. At one point Fang appears to get a bite out of it and the blood covering her face causes her to start reeling. The blood also seems to be black.
- Make Me Wanna Shout: Apparently frustrated at how Spear and Fang have been evading it for so long, it unleashes a hellish screech that causes Spear to clutch his head in pain and leaves him vulnerable to attack.
- Maybe Magic, Maybe Mundane: It's unclear whether the Night Feeder is just an exceptionally agile, strong and cruel beast or some magically enhanced monster.
- Mix-and-Match Critters: It bears a remembrace to the megaraptorid Maip macrothorax, with bits of Baryonyx and Therizinosaurus being thrown into the proverbial mix.
- Near-Villain Victory: The Night Feeder almost had Spear on a platter after making an ear-splitting shriek, making the neanderthal flailing his spear as a desperate attempt to fight back. At an ounce of coincidental luck, his weapon managed to create a spark of light that ignited the ground with fire. The mere sight of the flames made the murderous beast recoil in a highly panicked state and retreated without hesitation.
- Non-Indicative Name: Downplayed. It's called The Night Feeder and while it most certainly only attacks at night, one of its defining characteristics is that it doesn't eat the corpses in its wake, implying that it kills out of sadism.
- Nothing Is Scarier: Its hook, which it takes full advantage of, is being so fast and striking so brutally that no one knows what's actually attacking them. We see everything only from its perspective as it does so and never see it until the last minute of its episode, though still not completely clearly, as it's burning and wreathed in flames.
- Ominous Fog: Where the Night Feeder usually strikes is by slaying any living thing that are surrounded in misty areas in the forests.
- Ominous Obsidian Ooze: This horrifying beast has skin covered in a dark black slimy substance.
- Our Werebeasts Are Different: Implied. It’s hinted (though never confirmed) that the Night Feeder is the transformed version of a small bug-eating theropod Fang and Spear see at a river – possibly eating the flies drawn in by its rampages at night.
- Rage Breaking Point: The ravenous creature screeched at the top of its lungs like a demonic banshee out of nothing but severe irritation, and it wasn't able to entirely focus on killing the more "important enemy". Mainly because of how Spear was too evasive and agile to even slice him to caveman chunks, and Fang was possibly the first being to actually injure it. The nail in the coffin is when the duo tried yelling out to get its attention by intentionally running away in different directions, and by that moment letting out a deafening wail cemented the charade that enough is enough.
- Run or Die: This marks the second time after the infected argentinosaurus that Fang and Spear are in this sort of situation. The Night Feeder is so fast and strong, and tends to come out of nowhere giving almost no time to dodge, that Fang and Spear have no hope of defeating it in anything like direct combat. Inverted once the two figure out its weakness, which results in them killing it.
- Sadist: Seen best when it slaughters a herd, killing them one-by-one while basking in their fear.
- Serial Killer: Despite being a dinosaur, it kills for pleasure instead of food, enjoying the terror of its victims as it rips them to shreds.
- Weakened by the Light: It seems to have an extreme sensitivity to light or fire as a brief spark makes it pull back and a small fire is enough to send it into a full-blown retreat. Since it's covered in some kind of black goo, it may be highly flammable. Spear and Fang use this to their advantage by making strategic sparks to force it into a circle of trees that they ignite and form a ring of fire to prevent it from escaping.
- Whateversaurus: It seems to be some sort of theropod dinosaur with huge claws on its hands (the most likely candidate being a heavly stylized megaraptoran), but is unidentifiable beyond that. It's not even certain if it's a regular animal and not some supernatural monster.
- Why Did It Have to Be Snakes?: The Night Feeder will attack anything it sees but it quickly retreats at the sight of fire. When Fang and Spear realize this, they turn the tables by exploiting that fear.
