Sure, other Decepticons may scoff at his decision to go with a land-based alternate mode, but Knock Out couldn't care less. He knows the value of looking good and isn't afraid to let others know it. It's not simply his own lines he's interested in; he has an appreciation for well-built mechanical bodyforms of all sizes and functions... and a nasty penchant for tearing them apart after he's done admiring them. Slick, sly and snobbish, he's ostensibly the Decepticons' "medic", though he professes both a preference and proficiency for dis-assembly.
Both in the operation room and on the battlefield, Knock Out typically works with his brutish partner Breakdown. Knock Out is the speedster of the duo, swiftly striking his victim's vulnerables with his Energon prod in debilitating sneak attacks while Breakdown goes the "massive smackdown" route with his raw power.
