Megatron

Megatron is the evil ruler of the Decepticons who was one of the villains in Pooh's Adventures of The Transformers: The Movie. In the film, he and the Decepticons tried to destroy Autobot City on Earth and all the Autobots, but the Autobots and Pooh and his friends fought valiantly to defend themselves. Optimus Prime came to Earth and battled Megatron to the death. Despite being wounded, Optimus gave one last punch to Megatron and Megatron was defeated and carried by Soundwave to retreat with the other Decepticons and fly on AstroTrain. On their way, back to Cybertron, AstroTrain ordered to "Jetison some weight" and Megatron and the other dead Decepticons were cast out of AstroTrain and found by Unicron and Unicron changed Megatron to Galvatron.
