Dan is an optional boss in A Koopa's Revenge 2. The player must go all the way to Castle Mario while beating the minimum amount of levels possible or not pressing a single switch, and when he/she enters the boss room Mario will be replaced with Dan Hibiki.
Dan can be defeated with a single stomp or a powerup projectile.
He originates from the Street Fighter series as a joke character in which he was designed as a parody of rip-off characters.
- Dan is one of the bosses in Boss Rush so the player can fight him anytime without starting a new game
- Dan has a animation when he defeats you. some bosses don't have that.
