These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Fanon: Some fans like to play around with the idea that Mr. X is/was a real person, and that Dr. Wily either kidnapped him to take his place for the tournament, or that Dr. Wily actually killed him.
Fanon Discontinuity: Some hardcore fans like to consider 6 to be the final game of the Mega Man Classic timeline, since it is the last of the NES era Mega Man games, ignoring the events of Mega Man 7 and beyond; the fact that Dr. Wily isn't captured onscreen after this doesn't help the later games' case. Alternately, they skip directly from this game to 9, as 9returns to theMega Man 2-style and starts with Wily having been captured for a while.
