Chibi Megatron T-Shirt

Megatron's most consistent origin portrays him as having risen up from being an oppressed worker to a gladiatorial champion who took the legendary name of one of the original Thirteen Primes—Megatronus—as his own. He shortened his name when he became a political revolutionary who attempted to reform Cybertron's corrupt governing body and called for an end to its decrepit caste system. As the mentor of the young Orion Pax, Megatron preached that freedom of self-determination was the right of all sentient beings. When Megatron grew corrupted by his power, Orion would utilize his teachings against him as Optimus Prime. In most incarnations, Megatron would eventually meet his demise at Optimus' hands, only to later be resurrected as Galvatron
