Mega Man's search for his kidnapped sister and clues to clear Dr. Light's name is coming up with nothing. And Dr. Wily is still at large! Maybe he can save the day with the help of the six Robot Masters! Or are the robots wandering right into Dr. Wily's latest trap?
The third part of the Time Keeps Slipping story arc. CWU-01P attacks Mega Man, Ice Man, and Cut Man in the depths of Dr. Wily's old hangout but is defeated with teamwork. An elevator takes them to the same room they had fallen from before and had no clues to the whereabouts of Dr. Wily and Roll, which watches them with a Telly. Somewhat defeated, they return to the quarry where the Robot Masters are rebuilding. There they discuss what to do when Agent Roslyn Krantz joins them with news that, after Dr. Light requested her to see how Roll and Rock were doing, she wants to help. They call Dr. Light in Agent Stern's office who tells them about Oil Man and Time Man and the location of the place Dr. Wily was most likely located--a retired workshop used to test Oil Man and Time Man. Stern sends a vehicle to transport Rock, the Robot Masters, and Krantz to the workshop. In the vehicle, the Robot Masters give Mega Man their powers again, just in case.
Once there, Time Man and Oil Man take out most of the Robot Masters before Rock and Krantz even notice. All six of them are defeated easily as Mega Man and Krantz find Wily holding Roll captive. Time Man and Oil Man appear. Mega Man fights Time Man while Krantz tries to save Roll. Time Man instructs Oil Man to stop her but he ignores the order and disrupts Time Man's fight so that he has a chance to face Mega Man.
Mega Man gets off a few hits to Oil Man but is stunned when the Robot Masters appear, once again reprogrammed to fight against him.
