Autobot X is shutdown and put into storage. Wheeljack and Rachet beleive that they can fix Autobot X's bugs and use him as a temporary body for any Autobot that has been damaged in order to perserve their mind. Soon after, during a battle at a new Rocket base, Megatron damages Bumblebee and injures Spike. In order to save Spike, Doctors at Metro Hospital, suggest to Sparkplug to transfer Spikes mind so that they can opperate on his body. With help from Wheeljack, Sparkplug transfers Spikes mind into Autobot X, transforming him into Autobot Spike.
