Metal Mario in a Super Mario 64 promotional image.
The Metal Cap is one of the three Caps in Super Mario 64, which has the power to change Mario into Metal Mario. Mario activates them by hitting a Green ! Switch in Cavern of the Metal Cap, a secret course found within Hazy Maze Cave. Once he steps on the Green ! Switch, they will appear on every Green Block that he finds.
Usage[]
While in this state Mario gains temporary invulnerability and becomes much heavier, giving the player many advantages and a few disadvantages. For instance, Mario is immune to the toxic fog, but he will sink faster in quicksand. He can also sink in water, even in fast moving streams.
Appearances[]
Super Mario 64/Super Mario 64 DS[]
The Metal Cap first appears as a power-up in Super Mario 64. In this game, once Mario collects a Metal Mario Cap, his body transforms into metal, turning him into Metal Mario.
This item reappears in Super Mario 64 DS having the same abilities, except it can only be used exclusively by Wario when he gets a Power Flower, but there is no Green ! Switch or Metal Cap.
Super Smash Bros. series[]
In Super Smash Bros. Melee and subsequent Super Smash Bros. titles, the Metal Box has the effect of a Metal Cap, as just picking it up turns the fighter into metal. It turns the character heavier but, less likely to flinch and harder to send flying. It is also a option to turn all players into Metal forms in Special Smash and is a modifier in the single-player modes.
