Megatron Resurrected

Scorponok didn't know the consequences and stabbed the energon sword into Galvatron's Husk anyway. The energon from the sword caused the dead husk to absorb enough energon to make Galvatron reborn as Megatron, in a new body. He beats up Scorponok and Cyclonus told Megatron to stop and realized that Megatron should be blaming Alpha Q for using him. Megatron gain new powers like making Scorponok a Decepticon and controlling Alpha Q's Terrorcons. He latter shows up to meet his old rival and enemy Optimus Prime but injured Hot Shot along the way.
