Star Trek · Series · Space Probe, Sterilizer of worlds, Alien robot assuming the identity of an Earth-made robot
It's a pure machine which fails to understand emotions or human behavior. Its memory banks are damaged and goes under the fakely assumed objective to sterilize any imperfect lifeforms. Recognizes any humanoid with the name Kirk as his creator and obeys them. Nomad is actually imperfect and forcing the machine to realize this turns its own prime directive against the machine, resulting in a violent self-destruction event.
Ranked #15 of 32 in Star Trek by strength.
