 Mega Man prevails over a new group of eight powerful "Robot Masters" working under Proto Man: Star Man, Gravity Man, Gyro Man, Stone Man, Crystal Man, Charge Man, Napalm Man, and Wave Man. Mega Man then makes his way to Proto Man's fortress and confronts his fellow creation, who nearly destroys the protagonist in the process. However, a second Proto Man arrives just in time, revealing the first as Dark Man, one of Dr. Wily's newest robots. Mega Man vanquishes the impostor, then pursues Wily to his newest hideout, defeats him, and saves Dr. Light. However, the fortress begins collapsing, and while Mega Man is distracted from holding up the ceiling from crushing himself and Dr. Light, Wily manages yet another retreat. Just after Wily escapes, a familiar whistle is heard, and part of the ceiling is blasted away, allowing Mega Man and Dr. Light to also escape. As the two watch the castle collapse from a distance, their mystery savior is revealed to be Proto Man, who quietly slips off unnoticed.
