Brawn joined the misfit boys along with Preceptor and Cliffjumper. Coming through the Bay City Rift. To assist with the Decepticon problems and the secret Coalition base of Victorville.

The Autobots’ demolitions expert, is amazingly strong for his size. Due to his small stature, he often attempts to overcompensate by playing up his macho personality. He loves a challenge, be it rugged off-roading or charging headlong at foes several times his size. He has a lot of chutzpah, and a somewhat sarcastic sense of humor ever at the ready. Due to his machisimo, he sometimes looks down on noncombatant Autobots.

In addition to his great strength, Brawn is also so tough as to be almost indestructible. Almost.
