Metal Mario (form)

Metal Mario is the result of Mario gaining a metal cap.

Effects
During this form, Mario can cross fiery surfaces (such as lava) without getting burned, however he sinks underwater and can't jump as high (due to him being heavier) and falls at a faster pace. However, he is immune to all attacks, making him invincible.

Appearences

 * Super Mario 64, as one of the 3 different 'forms' which he gains from special caps.
 * Super Smash Bros., as a mini-boss.
 * Mario Golf, as an unlockable character
 * Super Smash Bros. Melee, as a mini-boss in the Battlefield stage in Adventure Mode..
 * Super Smash Bros. Brawl, playable when Mario grabs a Metal Box item.

Trivia
Due to Mario's shiny appearance while using a metal box, this powerup is commonly mistaken for Shadow Mario from Super Mario Sunshine.
