Who did Rocky Balboa not fight?

Rocky Balboa did not fight several notable boxers from the real world, including Muhammad Ali and Mike Tyson, as they were not contemporaries in the ring during his fictional career. Additionally, he never faced characters from other film franchises, such as Raging Bull's Jake LaMotta. In the context of the Rocky films, he also did not fight Apollo Creed in a rematch after their second bout, which ended in a draw.
