Rollbar is a member of the Commandos, the team that combines into Ruination. Though just as dedicated to fighting Autobots as the rest of his team, he's more restrained, especially in comparison to his fellow land-based Decepticon, Armorhide, though this is not hard. He's a practitioner of both Crystalocution and Metallikato, as well as jujitsu and other forms of Earthen Martial Arts. Curiously, he enjoys sauna baths and rainy days. Also, he has a vague Southern accent. Japanese name: Greejeeber (グリジバー Gurijibā)
