Punchmaster 3: Kickguru's Revenge featured a co-op mode where Punchmaster teams up with Mrs. Punch, his girlfriend. Despite not being married, she was still a "Mrs." which was due to a mistranslation in the original game. The name was so iconic, however, that they decided to keep her name.
The two remained unmarried until Punchmaster VI. Their wedding featured a very challenging QTE that most players fail on the first try. The segment was poorly received.
