You are 100% correct, Mega Man has nothing to do with Street Fighter. He is, however, available as a DLC for Street Fighter X Tekken and rather than give him his iconic look or even the look from Mega Man X, they chose to make him a creepy, short, fat guy wearing the costume from the original Mega Man's box art.
Please tell me this is a joke because if it's not then this is a major letdown. This is even worse than what they did to Rad Spencer when they turned him from being a clean cut marine into a stupid grunge rocker with those dreadlocks.
