Grimlock was one of the many Autobots to participate in the war against the Decepticons. Initially battling on Cybertron, he would follow Optimus Prime and the other Autobots to Earth via the space bridge. Secret Legacy, Part 1
Sent on a mission to infiltrate an underground fighting ring known as Bot Brawl, Grimlock soon found himself under the control of an anti-Cybertronian scientist known as Mandroid, thanks to a cognitive control badge. Used as the "champion" of Bot Brawl, Bumblebee was sent in to find out what happened to the lost Dinobot after months of no contact. The two ended on opposite sides of the ring in which Bumblebee, with aide from Malto family members Mo, Thrash, and Jawbreaker, were able to free Grimlock from his control badge. Upon being freed, the surly mechanical T-Rex went on a fire-breathing rampage that destroyed most of the arena and sent it's human audiences fleeing. Deciding to let him cool off, Bumblebee and his allies departed only for when they returned to find Grimlock long gone. Home, Part 1 Home, Part 2
