The Autobots and the Maximals are stuck on earth. And the Autobots have no way of getting back to their home planet Cybertron. But Unicron had changed you into his loyal servant. you are the only one serving him right now after Scourge, Battletrap and Nightbird were killed. You are very loyal to your master. But you don't remember your past or history. All you know is that you are ShadowStrike and servant to Unicron. You are with your master right now in deep outer space with him in his planet mode. You stood before him on a platform that was only showing part of his face. His two glowing yellow optics looking at you.
