Kago was voiced by Ron Perlman, and Uto was voiced by Brad Garrett.
In the end, they were defeated and punished by Mama Gunda.
Uto is a stupid, childish and dumb gorilla who likes poking Kago to provoke him on purpose. He also gets angry when somone provokes Kago. He also likes to throw things off the cliff.
Kago is a bulking, sadistic and violent gorilla who likes to smash rocks. He is shown to be angry when someone scares Uto.
Kago hates being pocked, while Uto hates being called a 'Banana Brain'.
Despite their antagonistic behavior, Uto and Kago are not completely evil as they were both concerned when Kala and the infant gorillas almost get knocked off the waterfall.
- Unlike Mama Gunda, Uto and Kago did not reform at all, but instead, they both got punished by Mama Gunda.
