Story
Doctor Wily learns of an experimental time machine known as the Time Skimmer at the Chronos Institute. He proceeds to steal it, and uses it to travel approximately 37.426 years in the future. While in the future, he experiments with the technology of the age and reprograms the future version of Mega Man, taking him back to his own time and renaming him Quint. Using the Time Skimmer and Quint, Wily once again revives a new set of Robot Masters, four of which guard his underground fortress. Dr. Light sends Mega Man at once to take them down and penetrate Wily's lair, but once inside, Mega Man finds another four Robot Masters awaiting him via teleporters. Mega Man manages to defeat all eight of his adversaries and engages Quint in combat, defeating him and obtaining his weapon, a pogostick-like device called the Sakugarne. With it, he makes his way to Wily's space fortress and defeats him yet again.
