Megatron

Megatron is the all-powerful Leader of the Decepticons and the longtime nemesis of Optimus Prime. Armed with a powerful Fusion Cannon, Megatron is more than a match for any and every Autobot that challenges him. Megatron expects every single one of his troops to respect him and follow his commands without question, especially Starscream, his treacherous First Lieutenant. The Decepticon Leader is more than prepared for any attempted betrayals thanks to his Communications Chief, Soundwave. Megatron desires to destroy Optimus and claim the Matrix of Leadership for himself, and will not hesitate to take human lives if it helps him accomplish his ultimate mission. In the year 2005, Megatron engaged in one final showdown against his nemesis, a battle which ended with his very own destruction, and opening way for the mighty Galvatron to take his place as Decepticon Leader.

Unlike most continuities where he transforms into a jet, Megatron transforms into a Cybertronian Tank.

Megatron's body was later used as the template for Galvawarp's newest creation: the mighty Nemesis Prime. It was later believed that Nemesis may've possibly been a reincarnated Megatron, though this was never officially confirmed.
