Shockwave was originally left to watch over Cybertron, but arrived on Earth to hunt for the All Spark shortly after Megatron. A peerless scientist with deadly efficiency and a cold devotion to logic, he is one of the very few who could rival Megatron.
In the console versions of the Transformers: The Game, Shockwave is not a playable character, appearing only as a boss Autobot campaign. The PSP version, on the other hand, allows the player to conrol Shockwave as a playable character.
