You mean like Ore 13 amped? Or better yet, the Megatron who looked kind of like the animated version, with Tron stripes?
Imo, that last one might be >>>>> just about anyone. Cannon that's so powerful it could accidently vaporize Prime AND the city behind him, at a fraction of full power. Durability enough to tank a direct hit from a tactical nuke, which almost KOed Prime at the very edge of it.
Not to mention, being hit in the head with his best shot, not even staggering, and casually beating him down before he "surrendered".
Hell, even Six Shot and Overlord can't just take Prime's best, without eating floor.
It's probably a good thing they tossed that body.. Way, way to powerful to beat without a major plot device.
