Optimus Prime

You're a Predacon. So, it's Cybertron, after the war ended. Megatron went into exile, hanging around somewhere within Cybertron. Since Prime returned, Energon began flowing through Cybertron again, so there was plenty of it on Cybertron. Optimus decided to check Cybertron's forbidden chat rooms, the very ones where the Predacons lived. He sort of got lost in the sight. It was a beautiful place, and the Predacons weren't particularly squabbling, living peacefully, but he found one Predacon, wounded, his wing damaged, and he found you. And now, your actions.
