Prime is out looking for the creators and fights something out in space, loses (why he's floating out there) then Unicron revives him and sends him back to earth to do something but he'll be "evil" and Mark and co. gotta figure out how to turn him good without killing him
Sounds about right. If Hollywood has any guts, they'll kill Bee off. It'll suck to see him go, but prime could always swap his "power" at the end to revive him or something. Idk. Something's gotta happen in this one tho to make me like the series again. I'm so against part 4, 85/ not even funny
