Killer Fish
- Killer Fish is a Beastformer from the Generation 1 continuity family.

Killer Fish (キラーフィッシュ Kirāfisshu) is one of the Decepticon-allied Beastformers attempting a brutal takeover of the planet Beast. His particular role in the Decepticon Beastformer forces is staff officer. He's a professional, brutal killer who uses a built-in sonar to track down his targets. He has a personal vendetta against Big Serow, who gave him an injury that still hurts. His rank is Emperor of Lennonia, the country on planet Beast in whose Wau River he was born, but whether this is a title he earned under the old regime before throwing in with Alligatron's rebellion or one gained by overthrowing Lenonia for the rebellion is unknown.
Sometimes there are lots of him.

The Killer Fish guarded the Decepticon stronghold in the nearby waters, and those Killer Fish leapt out to cut off Daniel and Wheelie's escape from the other evil Beastformers. Rebellion on Planet Beast
