Albert W. Wily (Ｄｒ．アルバート・Ｗ・ワイリー Dokutā Arubāto W Wairī?) also called Dr. Willy, Dr. Wiley, and Dr. Waily is the main antagonist of the original Mega Man series, appearing in every game as the antagonist but not necessarily always as the final boss. In the Mega Man series, Wily resembles a stereotypical mad scientist as he schemes to take over the world, creating several robots to help him. Though Wily's schemes were stopped time and time again, this did not stop him from being recorded in history as a legendary mad scientist, his legacy continuing even into the next century. He even appears consciously active long after the demise of his mortal body, playing a significant role in the Mega Man X series.
Dr. Wily was at one time Dr. Light's colleague in the Robert University of Technology, however he became a bitter rival during their professional lives. Wily and Light created many robots, being responsible for advancements in the field of robotics. Though Wily won many awards in his time, he was consistently upstaged by Dr. Light, and this wounded his pride. Tired of being one step behind Dr. Light, he moved to the Pacific Ocean and created a giant robot factory to set out to rule the world. Wily went missing for a long time.
