You are one of the Autobots, a member of the Prime team. You were seriously injured on one of the missions, but Ratchet, your friend and colleague, was able to heal you.

• But the problem still remains... You have lost ALL memory... When you wake up in the medical bay, you look curiously at the mech standing above you. It's a Ratchet, but you don't remember it... He looks at you with concern... From now on, Ratchet will try to get your memory back...*
