Megatron

Megatron (also known as "Lord Megatron" to his loyal servants) is the leader of the Decepticons. He originally dubbed himself Megatronus (named after Megatronus Prime), he was once a gladiator in the pits of Kaon, who grew ambitious and saw corruption within the caste system and sought to put an end to it, but with his rule. After leaving the gladitorial arena for the political one, he saw fit to shorten his name. When he was rejected by the High Council, he waged war on Cybertron and left the planet wasted.
