17화: 옵티머스 프라임과 벡터 프라임이 오버홀이 리오브레이커로 변한 정글 행성에 도착한다.
Optimus Prime and Vector Prime arrive on the Jungle Planet to meet up with Overhaul who sent a distress signal, but find that he has become Leobreaker. Red Alert theorizes that Cyber Planet Keys can turn a planet into a mirror image of Cybertron, and reformat Autobots. Optimus and Vector Prime discover that neither Leobreaker, Backstop, nor Snarl sent the distress signal. The trio are forced into battle alongside their new allies Snarl and Backstop against Megatron, Scourge, and their minions. During the course of the fight Optimus and Leobreaker awaken a power from within, combining into Optimus Prime, Savage Claw Mode! Meanwhile, Coby and the Mini-cons sneak off to Speed Planet, where Hot Shot is in preparation for the semi-final round of the Great Race. (Source: Wikipedia)
