An ironman is a kind of match similar to a crew battle, but it is 1 on 1. It is an idea of g-regulate on Smashboards based on Overswarm's idea. Both players pick 5 different characters. Each character starts with 3 stock, for a total of 15 stock. Both players pick their opening characters before the battle. They start on a random neutral stage, but they can agree on the opening stage. When a player loses all of his/her character's stock, he/she picks another character and counterpicks a legal stage. Each player starts the battle with his/her remaining stock (If player B keeps 1 stock after the battle, he/she must SD in the next match to start with 1 stock.) If a player loses his/her 15 stock, he/she loses the match.
