From Super Smash Bros. Brawl.

The Metal Box was a famous power-up, which it, along with the Vanish Box and the Wing Box, made its debut in Super Mario 64 for the Nintendo 64. The Metal Box held a Metal Cap Mario used to withstand enemy attacks, inability to breathe, and to step on switches and not be knocked away from jet streams while underwater. In Super Mario 64 DS, the Metal Cap and Box do not appear. Instead when Wario gets a Power Flower, he has the same abilities as Metal Mario. Metal Mario and the Metal Box appeared in the Super Smash Bros. series as an in-game extra and in Super Smash Bros. Melee as a trophy. After their debuts in games, the Metal Box and Metal Mario appeared in tons of Super Mario 64 fan art.
