All-Star Battle x1 (オールスター戦Ｘ１?) is an event match in Super Smash Bros. Brawl. The player gets to choose which character to fight as. The player fights against eight characters who are all newcomers and playable from the start. When the player KOs an opponent, there is a short delay before the next opponent appears. Only two opponents can be fought at a time. Use this time to KO the opponent the player is currently fighting before it becomes 2-on-1 again.
