The former leader of the Cybertron Elite Guard, Hyperdrive was an extreme liability to the Autobot cause towards the end of his command. He was unreliable, leading his forces on fool's crusades, and perhaps even more than a little insane. At least that's the story of the pragmatic new leader of the Elite Guard, Thunderclash, and he's sticking to it. As a result, Thunderclash mutinied and took Hyperdrive out of the picture. The Elite Guard breathed a sigh of relief as a result. Or at least, if robots breathed they would have.
