He plotted to rule the galaxy forever, but was defeated by Rodimus Prime who threw him out of Unicron's left eye chamber. However, Bowser found the broken decepticon leader and changed him back into Megatron as well as resurrecting Starscream, after the evnets of the Bionicle movie, to aid him in his evil scheme during the events of Pooh's Adventures of Scooby Doo and the Legend of the Vampire.
