The kaiju of the Pacific Rim draft script
Travis Beacham's Pacific Rim draft script has a ton of problems, but the kaiju are definitely none of them!
They're definitely a little different from the movie kaiju, biologically-speaking. They have red blood rather than blue, and there's nothing to suggest that toxic blood is a standard feature. There's also no reveal that they're clones with identical DNA.
(NOTE: I said earlier that it's unclear whether they have a hivemind, but I overlooked where Doctor Ivo Czerny said that there's a telepathic part of their brain that's tuned to signals from the Anteverse. The script doesn't use the word "hivemind," but the idea's pretty obviously there.)
Here's a list of the kaiju from the draft script:
TRESPASSER: The first kaiju to pass through the Interstice. Category 5. Attacked Osaka and killed Mako Mori's father.
Description: ...long and crocodilian, scabrously armored with rugged scales and scutes.
Notes: This is the first of several kaiju to share a name with a kaiju in the actual film. However, Trespasser - like all of the others - doesn't have much in common with its movie counterpart.
UNNAMED NIGHTMARE KAIJU: Early in the story, Felicity "Flick" Kincaid has a nightmare about her dead fiance Yancy Antrobus, and sees a kaiju.
Description: Hundreds of feet overhead, it's jagged jaws glow furnace-like from within. Ignescent saliva drips from it's teeth like molten napalm, fueling the encroaching wildfire.
Notes: Yeah, toxic glowing blood is cool, but saliva that sets shit on fire? That's absolutely metal, man.
DENGUE: Encountered by Newt and Flick in Miraflores, defeated by Puma Real.
Description: Arachnoid legs bristling with hairs. Scores of black eyes above a wide reptilian grin. Some unholy fusion of tarantula and dragon. An obscene, alien spectacle.
Notes: Dengue doesn't just resemble a tarantula - this beast can flick hairs like one, too! They don't appeal to be particularly damaging to the jaeger Puma Real, but at the size of arrows they're definitely a problem for the civilian population.
SLATTERN: Appears in one of Raleigh Antrobus and Mako Mori's training simulations.
Description: SLATTERN boasts a shape like an armless carnosaur: a thick, serpentine body on mighty raptorial legs. A head vaguely like a moray eel. A long tail, barbed at the end. It draws patient predatory circles around us, lean and powerful as a panther, scales shifting between jet black and iridescent blue in the fog-stifled light.
Notes: The way this is described sounds like it would look absolutely goofy if you drew it out, which is the opposite of a problem where kaiju are concerned.
TORTUGA: The kaiju that killed Yancy Antrobus. Shows up a lot through Raleigh's flashbacks.
Description: Tortuga is described as "hulking and turtle-like, carapace studded with jagged rows of bony plates." It's also described with a "trifurcated beak" and a "harpoon-like tongue."
Notes: On the one hand, Knifehead made a much more imposing figure than Tortuga. On the other... we don't really have enough turtle kaiju.
UNNAMED WOODLOUSE KAIJU: Lets off an EMP in Busan.
Description: Described as "a mountain of crustacean armor, like an outsized mole crab or woodlouse." And "Under its semi-translucent carapace, something writhes and shifts."
Notes: We were THIS CLOSE to having an isopod kaiju! Oh well, at least the kaiju skin mites look like isopods - I can't really complain too much, can I?
INVIDIA: That thing squirming around inside the isopod is the cat-3 kaiju Invidia! Fought and defeated by Raleigh Antrobus and Mako Mori.
Description: Described as "a spindly, mantid shape; tall as a skyscraper." She's described as having "a viper-like head" and "a set of long translucent wings."
Notes: Invidia can't fly, but her wings give her added mobility - and create vortices in the air that throw vehicles around! Also, Invidia fills the same narrative role as Otachi - she's the first kaiju that Raleigh and Mako defeat together, using their jaeger's sword.
OOLONG: Appears in one of Mako Mori and Raleigh Antrobus's training simulations.
Description: ...a chitinous crab-like dragon with black exoskeletal armor and giant pincers.
Notes: I think a spider-dragon and a crab-dragon in one movie might be a little redundant, but I feel like this beast has potential.
KOMODO: A cat-4 kaiju that attacks Minato Mirai. Defeated by Duc and Kaori Jessup.
Description: A long, lizard-like creature called KOMODO. Rows of teeth curl sloppily from his jaws. A baroque frill of coiled and braided horns embellishes his head. He scrabbles on six splayed legs; tail terminating in a spiked thagomizer.
Notes: Do you know how many kaiju have thagomizers? Not nearly enough of them. Also, this GINORMOUS beast (it's taller than Lady Danger!) spits acid. Definitely inspired Otachi a bit.
FULCRUM: A kaiju that attacks Minato Mirai along with Komodo. Defeated by Mako Mori and Raleigh Antrobus.
Description: Tentacles hide his jaws. Longer tentacles trail from his taloned arms. A scourge of tails whips the air behind him. He is kaiju FULCRUM -- an alien chaos of tentacles and dinosaurian limbs, his movements fluid and menacing, as much like a predator stalking primeval jungles as like a kraken prowling sunken ruins. He glisters with bioluminescence. He climbs ashore and rises to his full height -- almost a third bigger than the Mark-2. He lashes out with one of his long tentacles. The mech dodges and as the tentacle rakes past us, we see the rows of cruel, hooked claws running the length of it.
Notes: Not to sound like a kaiju groupie, but I love Fulcrum. This absolute BEAST tosses around these things called "Berserkers" - small tentacle-covered creatures that grab and rip apart anything they can get hold of before they swell up and EXPLODE. Oh, and when they rip its head off? Its body just keeps going! Role-wise, Fulcrum seems to have inspired Leatherback a bit - and perhaps inspired the tentacles on Leatherback's head?
UNNAMED WORMLIKE KAIJU: Briefly attacks Lady Danger.
Description: Described as "wormlike" and having "crocodilian jaws." That's all there is to it, really.
TENGU: Appears toward the story's climax, as Lady Danger approaches the Interstice. Defeated by Duc and Kaori Jessup.
Description: A horrific skein of dozens of viper heads on long sinuous necks erupting from a body like a naked bat.
Notes: Absolutely hideous beast! Makes me think Ghidorah and Rodan. I'd honestly like to see this one on film.
PHARAOH: Appears toward the story's climax. Defeated by Kaori and Duc Jessup.
Description: Something between a scarab and a bull, with
vicious mandibles and long horns like a rhino beetle.
Notes: This one just sounds like a scaled-up beetle. It's a little difficult to imagine that it would be anything other than a Very Good Boy if left to its own devices. I mean, it's probably only attacking the jaegers because it thinks they're mating rivals.
SCUNNER: Appears toward the story's climax. Defeated by Kaori and Duc Jessup.
Description: Beige-hued skin lends it a disturbingly human look; but grotesquely misshapen, joints bulging and twisted. A skull-like face, jaws over-crowded with jagged teeth.
Notes: I really think the sudden appearance of a human-looking kaiju would have been very jarring! It wouldn't have worked in the film that was actually made, but part of me wants to see a movie where this could have happened.
