Originally created as a backup of Optimus Prime, he had remained in stasis until megatron had taken him from the Ark. Megatron activated him and tried to make him into an evil decepticon to fight Optimus Prime, even giving him the same vehicle mode, but his autobot programming chip could not be corrupted. As a result, he fought back and stopped Megatron's plan and returned to the Ark to meet with the Autobots. He now acts as an elite commando for the Autobots. With his quadbarreled ion blaster and his shield, no decepticon stands in his way, not even Megatron . . .
