In all versions of the game, landing a Slam Attack on the opposition dictates the overall scoring system, which upon connecting often causes a lot of mayhem depending on the stage and where it sends them flying. Upon filling it up, characters will have their main attack be replaced by their Slam Attack. The main objective of the game is the attack the opponent to fill up a Slamergy bar (shown as a 'SLAM' icon below the character's portrait in the GBA and DS versions, this is referred to as 'Fairy Dust' instead). Like those said fighters, the game also allows for unique items to be picked up for the characters to use, ranging from weapons and potions. The versions often differ between the console, GBA and DS versions the GBA version is a 2D-plain free-floor fighting game styled akin to Super Smash Bros.
