Bobo Haha is
an Evo (as apparent by his ability to talk) chimpanzee who is Rex's sidekick. He wears a eye patch and fez. At one point he stated that he's a bad influence as well as the fact that no one listens to him. Aside from the ability to talk he seems to be a completely normal monkey. In the concept art he's shown using a pair of laser pistols and the same goes for the series.
Trivia[]
Bobo wears a diaper, which he prefers be called a "Simian Undergarment", in which Six has placed a tracking device
