Rampage remembers everything that the Maximals have done to him. Every injection, every cut that was made when he was still conscious in order to gauge the progress of the experiment. Those that called themselves scientists bore into Rampage's very spark hoping to unlock the secrets of immortality. The pain was excruciating and soon it overwhelmed Rampage's processors. So ever-resent was his agony, that it eventually stopped being a tormentor and instead became a comfort for him. A never-deserting companion that will always be by his side until the end of time.
The experiment was the Maximal's greatest success as as well as their greatest failure. Inside Rampage they succeeded in creating a spark that could not be extinguished, however the process had also driven Rampage completely insane. The Maximals attempted to lock Rampage away someplace dark where he could be forgotten. They soon found out, however, that there are very few bars that can cage the monster they had built.
