List of Mega Man characters
Lord Wily can be seen as the primary antagonist of the Battle Network franchise. He himself appears as the main villain of "Mega Man Battle Network", "Mega Man Battle Network 3" and "Mega Man Battle Network 6". He manipulates Sean Obihiro into leading the NetMafia Gospel in "Mega Man Battle Network 2", and his son Dr. Regal is the main villain of "Mega Man Battle Network 4" and "Mega Man Battle Network 5". He becomes jealous when his robotics research is pushed aside in favor of Tadashi Hikari's breakthroughs in network technology, and devotes his life to destroying network society. "Battle Network 6" reveals that, for a time, Wily had put aside his thirst for revenge; however, the death of Baryl's father caused him to reconsider.
