Klaxosaurs in General
Gargantuan monsters that feed on Magma Energy, klaxosaurs pose a constant threat to the Plantations. The FRANXX were created specifically to fight them. They are organized into various classes based on their size, with the Conrad-class being the smallest and the Super Lehmann-class being the largest.
- Alien Blood: A chemical shade of blue.
- Ambiguous Robots: Let's see. They bleed, they require sustenance in the form of Magma Energy, their name includes the root -saur, meaning lizard, and many of them attack by biting or clawing. The cast seems to treat them like normal living Kaiju. However, their hide seems to be made out of a dark metal, they sport Tron Lines aplenty, and more unique models include things like laser cannons, drills, rocket thrusters, and tank treads in their design. Not to mention their penchant for transforming mid-fight... Episode 19 reveals that they are equally parts organic and mechanical when Dr. Franxx observed a Klaxosaur carcass in the past. Episode 20 finally revealed that the Klaxosaurs are biological weapons with the Klaxosaurs themselves being the female pistil and the core being the male stamen.
- Asteroids Monster: The Gutenberg-class seen in episode 11. Due to its nature as The Worm That Walks, cutting into it just makes its severed body parts revert back into Conrad-class klaxosaurs that will harass whatever is attacking the main body.
- Attack Its Weak Point: Klaxosaurs can only be killed by destroying the core hidden deep within their bodies.
- Bizarre Sexual Dimorphism: At one point, far in the past, male and female Klaxosaurs diverged. Females eventually became the black-and-blue organic/mechanical beasts everyone is familiar with. The males in turn became their "core".
- Dark Is Not Evil: They may look like creatures of the dark, but they are trying to protect the earth from the Light Is Not Good aliens known as The Virm.
- Defeat Equals Explosion: Klaxosaurs explode in a shower of blue gore once their core is destroyed, much like the resident monsters of a certain other franchise.
- Dug Too Deep: The official story of their origins is that they are creatures that live near the areas where "magma energy" is mined.
- Evil Counterpart: Revealed to be one to the Franxx. The monsters called 'klaxosaurs' are actually transformed females of the klaxo-sapien race, with the males becoming the core and magma-energy to 'pilot' them. Though subverted, as the klaxosaurs aren't as evil as originally thought.
- Kaiju: With the exception of the relatively tiny Conrad-class, all klaxosaurs tower over the FRANXX. Gutenberg-class klaxosaurs in particular are as large in relation to the FRANXX as the FRANXX themselves are in relation to humans, and the wormlike klaxosaur from episode 4 is estimated to be several miles long. The Super Lehmann-class klaxosaur in episode 15 is literally the size of a mountain, and even it looks like a child's toy compared to the entity lurking in the Gran Crevasse.
- Magic Is a Monster Magnet: Magma energy is what powers the plantations and the FranXXs, and the klaxosaurs are attracted to them for some reason. This is because said magma energy is one of two forms the klaxo-sapiens have reduced to, the other being klaxosaurs.
- Non-Indicative Name: Both their original Japanese name and English name are different variations of dragons, dinosaurs or lizards. However, some of their appearances are taken from other animals like insects, snakes and even a crab.
- The Nudifier: The klaxosaur in episode 8 secretes a corrosive fluid that seeps into the FRANXX’s cockpits and dissolve the pistils’ suits. Hilarity Ensues.
- One-Gender Race: At least biological as they posses the XX chromosomes.
- Utimately averted. The males of the klaxo-sapien race become the cores of the klaxosaurs and the magma-energy that they feed on.
- Robeast: They appear to be biomechanical in nature, and they can only be fought effectively with a FRANXX.
- Theme Naming: Each class of Klaxosaur is named after a deeper transition layer of the Earth's interior, and, correspondingly, the scientist after which they were named, from the Conrad
to the Lehmann discontinuity. - Ultraterrestrials: As it turns out, the Klaxosaurs are derived from the human or human-like Klaxo-sapiens and the Earth is their home, having existed under it for ages.
- Voluntary Shapeshifting: Many of the larger klaxosaurs have the ability to shapeshift into various different forms. The Gutenberg-class seen in episode 6 takes it the furthest, going from essentially a walking office building, to a vaguely humanoid titan, to what is effectively a rocket-powered battering ram with legs.
- Was Once a Man: During the Gran Crevasse battle, what looks to be a petrified human falls out of a shattered klaxosaur core. Episode 18 also reveals that they have the same XX chromosomes as human females. Episode 20 finally revealed that the klaxosaurs are biological weapons the FRANXX are based on; the humanoid that fell out of the core was the klaxosaur's equivalent of a stamen.
Moho-class
The first klaxosaur variety seen in the series, a titanic armored quadruped with a massive head.
- Theme Naming: Named after the Moho discontinuity, the layer separating the Earth's crust from the mantle, which is in turn named after a Croatian geologist Andrija Mohorovičić, who discovered it.
- Wave-Motion Gun: Has an enormously powerful mouth-mounted energy cannon, though it has to reform its tail into a charging array to spin it up.
Conrad-class
A lesser klaxosaur variety, Conrads have round, blob-like bodies supported by four gangly legs.
Worm-type
A tunneling, serpentine klaxosaur of an unspecified class, with a head resembling the front of a tunnel boring machine.
- Sand Worm: Even more vast than the usual examples. It's several times as wide in the front as a Franxx is tall, and its body is absurdly long.
Gutenberg-Class
One of the largest classes of klaxosaur seen. To date, two have appeared: A giant humanoid klaxosaur with ability to transform from a box with horns, to giant humanoid kaiju to a literal gargantuan walking battering ram, and a jellyfish-like one that floats in the air.
- Does This Remind You of Anything?: At one point, the first Gutenberg-class turns into a giant boxed hammer with legs that pounds into Strelizia (now in beast form) again and again, with Zero Two inside screaming, struggling, bleeding, and trying to claw her way out like an animal. Pretty clear rape imagery.
- Expy: The first of Ramiel. Both are extremely powerful blue geometric shapes that can transform their body into other forms to attack enemies.
- Feed It a Bomb: The second Gutenberg-Class is defeated when Goro uses a spare battery pack as an explosive and detonates it from the inside.
- The Worm That Walks: The Gutenberg-class klaxosaur in episode 11 is actually a swarm of Conrad-class klaxosaurs that have merged together into a single entity. These smaller klaxosaurs break off from the main body whenever it takes damage, and it can voluntarily release them to serve as a distraction.
Super Lehmann-Class
The largest class of klaxosaur to date, so rarely seen that some even doubt their existence. They are very real, though, and one makes its presence known at the Gran Crevasse battle. It acts as a combination siege weapon/troop transport.
- Awesome Personnel Carrier: Has the appearance and function of a giant APC, carrying huge swarms of smaller klaxosaurs within itself. It even has tank treads in place of feet.
- The Juggernaut: Effortlessly able to plow through a Plantation without even slowing down. Even a Suicide Attack from the Plantation 26 Squad is only enough to barely injure it.
- Kaiju: Dwarfing even the already-massive Gutenberg-Class, The Super Lehmann-Class is comparable in size to a Plantation.
- Theme Naming: Danish geologist Inge Lehmann discovered not one, but two transitional layers, thus the largest klaxosaur so far is named Super Lehmann. Presumably, there should been another, smaller klaxosaur also named after her.
- That's No Moon: It was hidden underground at the Gran Crevasse site, with the giant mass on its back being mistaken for a mountain.
Star Entity - Warning: Walking Spoiler
An unknown class of klaxosaur that is awakened when the Gran Crevasse is torn open by Strelizia.
- Eldritch Abomination: A colossal, completely unknown entity among an entire race of giant, inscrutable monsters that has been sealed underground for God-only-knows how long. Humanity's cities and the largest class of monster, which the heroes were barely able to stop, are smaller than its finger, and it flattens both with what amounts to a wake-up stretch. And to cap it all off, what little we see of it before it retreats back into its hole looks human. The only word that can describe this thing is 'Terrifying'.
- Even after being converted into Strelizia Apus, it is still rather unsettling to look at, resembling a faceless, emaciated Spider Tank version of Strelizia.
- Fantastic Nuke: VIRM's final failsafe in case the Klaxosaur Princess were to regain control of Star Entity is to make it explode with enough force to destroy the planet.
- Giant Hands of Doom: Has the appearance of a human baby's arm and hand, which it used to destroy an entire Plantation. Whatever the rest of its body looks like is still a mystery.
- Giant Space Flea from Nowhere: Both in-and-out of the series, as it shows up with absolutely no fanfare or prior knowledge to anyone involved (save for the other Nines, the council, and Papa) when it appears.
- Humanoid Abomination: Possibly. At the very least its arm resembles a human’s, and the arm alone is so incomprehensibly vast that the mountain-sized Super Lehmann-class klaxosaur fits in the palm of its hand. The mere act of it grabbing and dragging said klaxosaur away carves a canyon into the ground and not only destroys most of Plantation 13, but leaves what’s left of it standing on a mesa formed by the gap between its fingers.
- Humongous Mecha: APE modifies it into a colossal Franxx unit based on Strelizia with the intent to use it to wipe out the klaxosaurs.
- Kaiju: If the Super Lehmann-class was considered gargantuan even by other klaxosaurs, this one makes it look like a gnat in comparison, with just its arm reaching into the sky and tearing apart a massive portion of the Earth and flattening most of the Plantation and a majority of its forces in the same sweep.
- Knight of Cerebus: Just when things were starting to look up for the cast as Hiro and Zero Two finally overcome their issues, and confess their feelings for one another as they defeat the Super-Lehmann class and open the Gran Crevasse... this thing shows up and almost instantaneously throws one hell of a curve ball to the cast.
- Sealed Evil in a Can: What the Gran Crevasse appears to be for this creature.
- Turned Against Their Masters: Twice. First, APE converts it into Strelizia Apus to use as the final weapon against the klaxosaurs. Then its hijacked by the Klaxosaur Princess, and later Hiro & Zero Two, to wipe out the VIRM vanguard fleet.
- Walking Spoiler: Its sudden appearance at the very end of episode 15 leaves a lot of questions about everything in the show thus far.
The Klaxosaur Leader - Warning: Walking Spoiler
Voiced by: Rie Kugimiya (Japanese), Luci Christian (English), Eva Andrés (European Spanish)
001 is the Klaxosaur Princess, the leader of the Klaxosaurs with an unknown relation with Papa.
- All for Nothing: When caught in VIRM’s trap and paralyzed, she laments about how all the efforts of her people have gone to waste and gives up on fighting any longer in contrast to Hiro who still tries to hold on.
- Ambiguously Evil: Her reasons for leading the Klaxosaurs are not clear and while the Klaxosaurs act as enemies to the main characters, some of the reveals of Papa and the Council's nature leave the evil part in question and she calls the council human-wannabees.
- Episode 19 heavily implies she might be a natural Klaxosaur, possibly making her aggression Blue-and-Orange Morality in defending her race.
- Episode 20 finally revealed that she isn't "evil" since she is trying to protect the Earth from the VIRM.
- Ascended Extra: Her manga appearance makes her much more of a threat to the Plantation members and APE, with her personally kidnapping Zero Two, mind jacking Nine Delta, and being the subject of the final confrontation.
- Attack Animal: She’s accompanied by a pair of snakelike klaxosaurs which make short work of APE’s messengers once she’s had enough of their babble.
- Big Good: She turns out to be defending the Earth from an alien race known as the VIRM.
- Combat Tentacles: She has half a dozen tentacles growing out of her back, and she uses them to perforate Tarsier in episode 17.
- Didn't See That Coming: For all her calm demeanor and patience, the Klaxosaur Princess never even considered that VIRM/APE would have placed a failsafe into Star Entity in case she managed to retake control of it from them, despite knowing it had been modified heavily by them. So when she does just that, the trap VIRM had set activates in response before she can actually do anything else. This results in Star Entity, her trump card, being disabled and turned into a bomb set to destroy Earth, and she herself being immobilized and unable to do anything due to a virus VIRM set into Star Entity that would activate only if the Klaxosaur Princess was the one who tried to use it - meaning they had foreseen what she would do and her efforts were basically for nothing from the start. Thankfully, it ends up not going to waste though thanks to Zero Two and Hiro’s efforts.
- Slightly downplayed in that everyone, even Dr. Franxx and several APE members themselves are completely caught off guard by this as well. It’s possible that since the original plan was to use Star Entity against the klaxosaurs, the Klaxosaur Princess didn’t think they’d modify it to be destroyed in any circumstances, considering whoever controls it essentially already had victory. Though considering she was aware VIRM had infiltrated APE and actually knew what VIRM was like from her previous interactions with them, something no one else had, she still should have at least considered it.
- Fangs Are Evil: 'Evil' may be a stretch given how little we know of her & her relationship to humanity, but her mouth is full of sharp fangs that are strong enough to tear off limbs.
- Good Is Not Nice: While she is ultimately fighting to protect the Earth from the VIRM, she doesn't show much regard for humanity. Given how they've been waging a genocidal war against her people and using their desecrated corpses to create the Franxx, though, it's pretty understandable.
- Humanoid Abomination: She’s effectively a human with blue skin, Facial Markings, horns, and some tentacles growing out of her back. She'd be a Rubber Forehead Alien if not for her almost supernatural powers and implied longevity.
- Last of Her Kind: She's actually the last Klaxo-sapien since the rest of her people were either desroyed by VIRM or became Klaxosaurs.
- Make Me Wanna Shout: She lets out a shrill note that incapacitates all but one of APE’s messengers when they come to demand her surrender. It also apparently able to send complex messages directly to the brain of who hears it, though the audience doesn't get to listen in to what she said.
- The Man Behind the Monsters: Is mostly-humanoid, unlike the multitudes of Klaxosaurs under her, however she still considers herself a Klaxosaur and even refers to them as her brothers.
- Mundane Utility: She can form her tentacles into a throne when she wants to slouch.
- Not So Stoic: The Klaxosaur Princess was icy calm and stoic to the point where she never changed her facial expression once, even when tearing off Dr. Franxx’s arm and confronting VIRM. But when VIRM’s trap in Star Entity activates and she finds herself paralyzed by their virus, she’s reduced to screaming in blind rage and panic and thrashing about hopelessly in Strelizia’s cockpit as the virus continues taking over.Klaxosaur Princess: (screaming telepathically) YOU IMPERTINENT FIENDS!!!
- Older Than They Look: Played for Laughs, in the 4 panel manga, where Hiro mistakes 001 for Zero Two's younger sister because of her petite body. She didn't take kindly to that remark.
- Oni: Visually at least. She has a horn and her skin is blue which is the second common color. However, her behavior is much more low key when compare to the common portrayal of onis, which is fitting when compared to Zero Two. Dspite her calm demeanor, she can be rather ruthless and violent, like when she ripped Dr. Franxx's arm with her mouth.
- Only Known by Their Nickname: Her real name is unknown. She's only ever referred to as either the Klaxosaur Princess/Princess of the Klaxosaurs or 001.
- Shoot the Messenger: She’s completely unimpressed when APE sends messengers to demand her surrender in episode 17, and slaughters them all. Most importantly she refers to APE as human-wannabees, implying there's more to the war than what is known.
- Technopath: Episode 20 show that she can shut down Strelizia with a gesture, take control of it by inserting her tentacles into the pistil’s station (causing it to turn black and blue like a klaxosaur in the process), and activate other klaxosaur technology without touching it. Of course, it is her people's technology in the first place.
- Telepathy: Is able to communicate by speaking into the minds of others. She also uses this power to control Delta's body and attempt to steal Strelezia in the manga. She can accomplish this because of Delta's blood ties, since the Nines are clones of Zero Two and therefore share DNA with her.
- Time Abyss: Episode 21 confirms that she is at least 60 million years old.
- White Hair, Black Heart: Leads the Klaxosaurs and appears cold in personality the Black Heart part is still played with when Papa and the council are not good as they seem.
