Though officially a peace enforcer, Peace Officer Brutus secretly led a gorilla extremist gang of 'Ape Supremacists' (operating like the Ku Klux Klan) who terrorized the humans and their sympathetic ape friends. Brutus murdered his wife Zena when she threatened to expose him, Brutus then laying the blame on Jason and so beginning their long saga. He was also in league with, first, the Inheritors, then the Gorilloids, to take over the ape city but was ultimately captured.
- Brutus is exclusive to the continuity of the Planet of the Apes comic books published by Marvel Comics.
- Another gorilla soldier named Brutus appeared in issue two of Star Trek/Planet of the Apes: The Primate Directive. Most likely these are a coincidence and are not intended to be the same character.
