Following the expiration of their licensing agreement with professional boxer Mike Tyson, Nintendo chose to re-release Mike Tyson's Punch-Out!!, sans Tyson. To compensate, Nintendo created Mr. Dream, a sprite swap of Tyson, and rebranded the game as Punch-Out!! Featuring Mr. Dream. Despite the rest of the game being identical to the Tyson version and Mr. Dream retaining Tyson's move set, the Mr. Dream version of Punch-Out!! is widely considered inferior due to the notion that as a character, Mr. Dream is simply not as intimidating nor as interesting as Tyson.
Mr. Dream has yet to appear in any other video game since his debut.
