Some have biological components with which to interface with their pilots, and some are partially biological themselves, such as in Neon Genesis Evangelion, Eureka Seven, and Zoids.
Mõnedel on bioloogilised komponendid, mille abil saab nende pilootidega ühineda, ja mõned neist on osaliselt bioloogilised, näiteks Neon Genesis Evangelion, Eureka Seven ja Zoids.
