Rockman 2 - Dr. Wily no Nazo (Japan)

About

After his initial defeat, Dr. Wily, the series' main antagonist, creates his own set of Robot Masters in an attempt to counter Mega Man: Metal Man, Air Man, Bubble Man, Quick Man, Crash Man, Flash Man, Heat Man, and Wood Man. He also constructs a new fortress and army of robotic henchmen. Mega Man is then sent by his creator, Dr. Light, to defeat Dr. Wily and his Robot Masters.[7] Mega Man defeats the eight new Robot Masters and then challenges Wily himself.[8] During the final fight, Dr. Wily flees into the caves beneath his fortress and when Mega Man follows, attempts to trick Mega Man into thinking he is a space alien, but Mega Man defeats the alien revealing it to be a holographic projection device which malfunctions showing Dr. Wily at the controls. After the scientist begs for mercy, Mega Man spares Wily and returns home.
