Transformers

MegOp

Megatron/Optimus Prime

Before the war, they were Megatronus the gladiator-poet and Orion Pax the archivist who believed in him — continuities like Transformers: Prime and IDW canonize that the Autobot and Decepticon leaders began as brothers-in-arms or closer. Four million years of civil war between former idealists gives the ship operatic scale. MegOp has anchored Transformers fandom for decades.
