Otachi is a Category IV Kaiju featured in Pacific Rim.
Otachi's anatomy consists of two short legs and long, four digit hand-wings that bear a striking resemblance to those of a Pterosaur which she can use to fly. Her wings are stored inside her forearms for protection, folding out from an elongated, double-jointed fifth digit. Otachi is capable of flight to the edge of space, even when her legs are carrying something as heavy as a Jaeger. She has a long tail with bony plates along her spine, as well as three prehensile pincers on the end of the tail; the tail is a potent weapon that can be used as a club or claw against Jaegers.
Her bottom jaw is capable of splitting in two to spit from the pouch (below the maw). Her tongue has a flowering and bioluminescent structure which she apparently uses either as a grasping mechanism or sensing organ (similar in function to a snake's vomeronasal organ). She also has a sac under her neck that can be engorged to spit a blue, extremely corrosive acid, as seen when it melts the thick armor of a Jaeger and when it it easily liquefies the side of an office building.
