Onibaba is one of the major antagonists of the Pacific Rim franchise. It first appeared serving as a flashback villain in the 2013 film titled simply Pacific Rim. It then returned in the 2018 sequel Pacific Rim: Uprising, this time as a simulation villain as part of Jaeger Combat Simulator. It also reappears in the video games titled Pacific Rim: The Video Game and Pacific Rim: The Mobile Game, serving as a playable character in the former and an unplayable boss in the latter.
A crustacean daikaiju of Category II created by Precursors as a soldier in the Kaiju War with humanity, Onibaba attacked Japan's capital city Tokyo on 15th May 2016 and stopped all of the military's attempts to kill it upon finding a little girl named Mako Mori. The creature has chased her relentlessly throughout Tokyo's streets until cornering her in a dead-end alley. However, before Onibaba had a chance to kill an innocent girl, Jaeger Coyote Tango arrived at the city and after combating the crustacean terror for three hours, Onibaba was finally punished for its crimes.
Nineteen years later, Onibaba became part of Jaeger Combat Simulator. Grown massively in size and strength, the monstrous crustacean has proven itself to be more than a match for Mark VI Jaegers. When Amara Namani alongside Suresh Khuran were recruited for Jaeger Pilots for Titan Redeemer, Onibaba has been successfully defeated in simulation combat.
Like all kaiju within the Pacific Rim universe, Onibaba is an extremely destructive and hostile creature created solely to bring annihilation to all life on Earth. However, in addition to its hostile nature, Onibaba displays a strong sense of sadism in chasing defenseless prey for fun. Even if she will not provide any sustenance to such an immense monster, Onibaba still opted to kill Mako Mori to not leave any survivors of its attack. When interrupted by Coyote Tango's arrival, Onibaba aggressively abandoned its goal of killing the girl and proceeded to engage Jaeger in combat.
Extraordinary for the rest of kaiju seen in the film, Onibaba is vaguely a crustacean creature of immense size, reaching 188 ft. in height and 2,040 tons in weight. Its entire body is covered in a spiky dermal exoskeleton which is azure blue and bright orange in color, accompanied with bioluminescent-yellow veins spread across the entirety of its body. It moves on two sets of massive arthropodal limbs, which allow Onibaba for short bursts of speed in the left and right directions. Aside from a larger main set of upper limbs with pincer claws, Onibaba possesses a smaller set of limbs with three digits on its stomach. Monster's head is protected from attacks from the rear by two columb-like protrusions, while its head itself is small, has a tall crest, and lacks a neck. Onibaba's facial structure is compromised of one pair of small eyes, as well as bifurcated jaws that split in many directions whenever kaiju opens its mouth.
Powers and Abilities
- Crustacean Anteverse Kaiju Physiology: Onibaba possesses physiology akin to that of Earth's crustaceans, as well as Kaiju from a dimension known as Anteverse.
- Advanced Strength: Thanks to its immense size and tank-like build, Onibaba is easily capable of swatting jet fighters from the sky, tearing buildings apart and destroying almost any non-Jaeger man-made structure. Postmortem analysis indicates its primary foreleg claws had a crushing force of 50,000 psi, which are confirmed by analysis of damage to Coyote Tango’s cranial frame and Conn-Pod. According to its stats in Pacific Rim: Man, Machines & Monsters, Onibaba has rank 6 in terms of strength, setting it above kaiju like Trespasser and Mutavore. In the video game, Onibaba is shown to be powerful enough to tackle Jaegers and Kaiju larger than it to the buildings and ships.
- Advanced Durability: Onibaba's armored outer shell is able to withstand attacks from jet fighters with little to no damage, as well as physical and energy strikes from physically stronger than itself Coyote Tango. Stats from Pacific Rim: Man, Machines & Monsters state that Onibaba is one of the best armored Kaiju, ranking its durability at 9. This makes the crustacean Kaiju superior to Scunner, Otachi, Raiju, Trespasser or Knifehead, although it is overshadowed by Slattern, Mega Kaiju and Copperhead.
- Advanced Speed/Agility: While not shown in the film, Onibaba charge at its opponents at high speeds on land in the games thanks to its arthropod-like legs comparatively similar to some species of crabs.
- Advanced Senses: Having crab-like eyes, Onibaba has an enhanced vision and sense of smell, allowing it to easily track small targets like Mako Mori through the districts of Tokyo.
- Caustic Blood: Like in the case of all Kaiju, Onibaba possesses an extraterrestrial phosphorescent component in its blood known as Kaiju Blue, which can cause environmental pollution and deadly diseases. In Onibaba's case, its caustic blood is moderate similar to Kaiju like Knifehead.
- The name Onibaba is a reference to the 1964 Japanese historical drama film of the same name, as well as creatures from Japanese folklore.
- According to the novelization of the first film, Onibaba's skull was posthumously mounted at the side of Mount Fuji as a warning sign for future kaiju.
