Bomb Mario

Bomb Mario is a form that Mario can only assume in Super Mario Land 2: 6 Golden Coins. The form does not appear in the game itself, but rather during the Select Screen. If Mario, instead of choosing one of the three Warp Pipes to continue a saved progress, jumps beneath the "Clear" block to the right, he will transform into Bomb Mario. When selecting a Pipe in this form, its associated saved data will be deleted.

Bomb Wario later appears in Wario Land: Super Mario Land 3 and later in Virtual Boy Wario Land, which use an identical method of deleting files.
