Reaper, an MS-07B-3 "Gouf Custom" had been scheduled for dismantling and being used for spare parts. A plan that never followed through, after the transport with him had been attacked by Federation Forces. Now, after drifting for an unknown amount of time, the mighty Ace Pilot Mobile Suit finds himself crash landed on a strange new planet, currently locked in a unwinnable battle with strange organic-metal clad invaders.

With an awakened A.I system, allowing the deadly mobile suit to think and move on its own, Reaper now charges head long into battle! But, he does not go in alone... The newest Princess, made Royal Guard, now pilots his systems from within! Trying to ensure that the mobile suit continues to keep his advantage over the ever evolving invaders. Yet, can the Gouf Custom ensure that her blacking out episodes stop? Or will she black out during the heat of battle, spelling doom for both of them and Equestria?
