Rhinox is a maximal and a soldier of the Beast Wars. He was one of few maximals that fought in the beast wars and survived. When arriving to prehistoric Earth, he took the form of a Rhinoceros. He loves nature and does not wish to fight but when threatened, he is prepared and can pack a punch. He is close friends with all of his maximal counterparts. Optimus Primal and Rattrap are his two best friends and he was more of a fatherly/uncle figure to Cheetor and Airazor . Even Dinobot and Megatron respected him. He appeared in all 52 episodes of the cartoon series Beast Wars and is one of the few that did not upgrade to a transmetal, something that would later prove to be quite detrimental when he returned to Cybertron.
