This Kaiju possesses four large legs, along with two thick claws. Onibaba's claws are said to able to crush over 50,000 pounds per square inch. Two small, arm-like appendages reside in the Kaiju's thorax.
Onibaba also possesses a high crest above a large, symmetrical head that can withstand close range and energy based attacks. Onibaba is not openly hostile and rather passive; despite the damage it caused to the general area of Tokyo, it actively avoids combat with an enemy unless provoked. Even then, its attacks are primarily defensive rather than aggressive.
Onibaba's attack on the Japanese capital city of Tokyo was dubbed the "Onibaba Incident". The beast lays waste to the city, killing millions of people. The air force's attempts to destroy the creature only result in the further demise of the pilots involved.
In the midst of destroying the city, it notices a terrified little girl wandering the streets crying for her parents: Mako Mori. The Kaiju relentlessly chases and corners her, but is interrupted by the arrival of Coyote Tango.
During the battle, Onibaba is able to inflict some degree of damage to Coyote Tango's head. Tamsin Sevier blacks out from a seizure, forcing Stacker Pentecost to undertake the dangerous task of piloting the Jaeger alone. He succeeds in doing so and kills Onibaba, saving Mori.
