Rhinox was a Maximal and Optimus Primal’s oldest friend, although it seems Rhinox has known Rattrap for even longer, stating he was his best friend in the episode A Better Mousetrap. His beast mode is in the form of a large brown rhinoceros (it rarely appeared in the second season, and was never seen in the third). He has two machine guns as weapons, which fans have nicknamed the “Chainguns of Doom”. He usually stays in the base and acts as an engineer and second in command of the Maximals. Rhinox created the Maximal Base’s automated defense system, dubbed Sentinel.
