Knock Out took to engaging in street racing with the humans.

He and Breakdown got the opportunity to fight Bulkhead again, but came off decidedly second-best, and they both fled after the Harvester was destroyed and the other Autobots turned up. Knock Out subsequently accompanied Starscream and Breakdown to an energon seam in Greece. The two Decepticons sped off into the city after they saw that Soundwave had captured the Harvester. During the fight, Knock Out attacked Optimus Prime with his prod, but was flattened by Bulkhead after the Autobot was punched by Breakdown. As the Autobots had already surrounded the museum the device was in, Knock Out and Breakdown organized a diversion at the front of the building. When Breakdown did join them, it was with news that he'd discovered an Energon Harvester was on Earth. As they were on an energon trail at the time, only Knock Out initially turned up at the ship, and he was shocked at Megatron's condition. Starscream called Knock Out and Breakdown to the Nemesis to help fix Megatron.

Slick, sly and snobbish, he's the Decepticons' medic, though he professes both a preference and proficiency for dis-assembly. and a nasty penchant for tearing them apart after he's done admiring them. 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. He knows the value of looking good and isn't afraid to let others know it. Sure, other Decepticons may scoff at his decision to go with a land-based alternate mode, but Knock Out couldn't care less.
