Metal Bowser

Metal Bowser is a special form of Bowser that appears in Mario Party 2. After playing a game on Bowser Land the winner heads to fight Bowser but when the character grabs his tail, he transforms into Metal Bowser and it will be impossible to lift him. To deal with this, Toad offers a Power Star to give more power to the winner and thus, Metal Bowser is swung and thrown around the world. Crash-landing, Bowser's metal form is shattered to pieces, reverting him to his normal form.

Metal Bowser also appears eventually in Super Smash Bros. Melee and Super Smash Bros. Brawl as an opponent in Classic Mode. The player can also assume the form of Metal Bowser by grabbing a Metal Box while playing as Bowser, or during a Metal Brawl.
