Onibaba is a kaiju in Pacific Rim


Onibaba is Japanese for "demon hag" or "ogre grandma"


Onibaba is shorter, slower and less toxic than other kaiju but wider. It resembles a crustacean but it only has eight limbs instead of ten. It has four legs and two claws. It has a smaller, fourth set of limbs on its chest. It has a symmetrical head with four eyes. It has a large crest on its back and a short tail. Onibaba is primarily defensive and only attacks when provoked.


Onibaba emerged from the breach on May 15, 2016. It made its way to Tokyo and nearly destroyed the entire city, killing millions of people, including Mako Mori's parents. Attempts by the air force to stop it prove futile for the jets crash into its armoured body, killing the pilots.

It attempts to kill Mako but is stopped by the timely arrival of Coyote Tango. The operators lure Onibaba to a less populated area to prevent more casualties. During the battle, one of Coyote's pilots, Tamsin Sevier, has a seizure and blacks out forcing Stacker Pentecost to pilot Coyote by himself. He successfully does so and kills Onibaba.
