Iron Man (Peppermint Armor)
Back when Tony Stark was drinking, the annual Stark Industries Christmas party was quite the event - a wonderful mix of human debauchery with robot bartenders. During one memorable Christmas Eve party, Tony was seen stumbling off, muttering something about needing more peppermint schnapps. The next morning, Tony was found passed out in his workshop on top of a new set of red and white striped armor. Thus, the Peppermint Armor was born.
Tony only wore the armor twice - once that morning to fight M.O.D.O.K. and his kamikaze robot reindeer, and once years later at a White Stripes concert.
By the way, the Peppermint Armor is my own creation. It has never appeared in any comic.
