A variant of the original Megatron, from the G1 side of the Multiverse. Typically forms the right arm for maximum cannon firepower.

Megatron combines brute strength, military cunning, ruthlessness and terror. Aches to return to Cybertron to conquest after destroying all Autobots on Earth. Plans to possess all Earth resources. Incredibly powerful and intelligent. Fires nuclear-charged fusion cannon. Can link up inter-dimensionally to a black hole and draw antimatter from it for use as a weapon. No known weakness.
