Megaman is the main protagonist from the original era of Megaman. He was one of the first robots built by Thomas Light, an engineer in robotics. Initially a helper in the lab he'd become a combat robot to help foil the schemes of Light's rival, Wily. Following a sense of justice he'd constantly go against enemy and former fellow robots alike. After months or even years of fighting for justice his fate would be unknown by the time the new era of robots would be created.

He's built to resemble a young man, when not wearing his combat armor he can wear casual clothing. His hair is messy and brown and his eyes are blue. When in his armor he sports a light blue bodysuit under darker blue armor over his arms, legs, waist and wears an open helmet.

As a robot converted for fighting he is capable of things such as transforming his arm into a Mega Buster cannon, use the bottoms of his feet as thrusters and make use of the power of vanquished robots as his own with the Weapon Copy System. He also has the ability to merge with his companion dog Rush for varying situations with Rush Adaptor.
