Power Punch 2
actually started its life as a sequel to Mike Tyson's Punch-Out!!
, however as Tyson was facing a rape trial at the time, Nintendo dropped his name and developed a lookalike for the main character. Eventually the poor quality of the game (which had been licensed to third party developers) caused Nintendo to disavow the sequel and thus had to be published by American Softworks under the name Power Punch 2. Note that there is no Power Punch 1, the number being merely a reminder of what the game was originally supposed to be.
