War for Cybertron Nemesis Prime. Before the great Cybertron war, Nemesis and Optimus went to the Omicron Defense Academy together. They were known to be 2 of the top bots and very similar to each other, but Nemesis always finished second to Optimus at everything despite being bigger and stronger. His jealousy, combined with a serious temper problem, got Nemesis expelled just before graduation. He never got over that incident. His anger and jealousy led him to the brink of insanity and he became addicted to modifying himself. When Megatron began the war and bots began taking sides, Nemesis didn't even seek Megatron's approval. He quickly decided he was a Decepticon, carved the symbol into his abdomen, and went on a raging psychotic warpath to destroy Optimus. Many millennium later, Megtron will have Nemesis sent to a planet called earth through the space bridge. He will subject Nemesis to an experiment because of his structural likeness to Optimus Prime. Nemesis will one day take the same form as his... nemesis. He will become Nemesis Prime.
