A Cap Block is a type of block that first appears in Super Mario 64. In the original game, Cap Blocks come in three colors, each one containing a different power-up.


Super Mario 64 / Super Mario 64 DS[edit]

In Super Mario 64, all Cap Blocks are intangible at the start of the game, reminiscent of the four ! Blocks from Super Mario World. When one of the three Cap Switches is activated, all Cap Blocks of that color solidify and drop a cap power-up upon being broken open.

In Super Mario 64 DS, the three colored ! Blocks are reduced to one red ? Block, which is simply referred to as such. Red blocks contain either Power Flowers, which give different abilities depending on which character obtains them, or Wings in certain levels for Mario. If anyone other than Yoshi hits a red block without his cap, however, a Bob-omb will come out instead.

A different set of Cap Blocks exists unused in Super Mario 64 DS, and they provide the player with Mario's cap, Luigi's cap, or Wario's cap.

Super Smash Bros. series[edit]

A Metal Box in Super Smash Bros. for Wii U

The green block appears as an item in every installment of the Super Smash Bros. series starting with Super Smash Bros. Melee, under the name Metal Box. Much like in Super Mario 64, this item causes characters to become coated in metal for a short period of time. Unlike in Super Mario 64, they have to simply grab or directly hit the box to become metal, as opposed to jumping under it and causing the Metal Cap to emerge from it. They become heavier and fall faster, making it harder to directly KO them by blasting them away, but making it harder for them get back on the stage. Getting hit causes the duration of the power-up to shorten. The Final Smash forms Giga Bowser, Wario-Man, Mega Lucario, and Giga Mac are completely unaffected by Metal Boxes. Also, when a character becomes metal, their voice is removed.

From Super Smash Bros. Melee onward until Super Smash Bros. Ultimate, each game of the Super Smash Bros. series has a trophy of the Metal Box. In Super Smash Bros. for Wii U, the trophy erroneously states the Metal Box appears in Super Mario 64 DS, which replaced the colored caps with multiple characters, and their Power Flowers are all found in red blocks.


In the Super Mario Mash-up in Minecraft, the red, green, and blue Cap Blocks appear as paintings, along with a yellow block from Super Mario 64.

Trophy information[edit]

Super Smash Bros. Melee[edit]

Name Image Game Description
Metal Box Metal Box Super Mario 64
First spotted in Super Mario 64, the Metal Box holds the power to turn your character briefly into heavy metal. Your mass is exponentially greater while metallic, making it difficult for others to throw you. Be careful though: not only will you move a bit slower, but you'll also fall much more quickly than you ordinarily would.

Super Smash Bros. Brawl[edit]

Name Image Game Description
Metal Box BrawlTrophy496.png N64 Super Mario 64 A green box that transforms whoever attacks it into metal. In metal form, you're a lot heavier than normal, so middling and even strong attacks don't move you too much, and standard attacks won't even make you flinch. The time you spend in metal form decreases with the damage you take. In Super Mario 64, the weight of the metal form allowed you to walk underwater.

Super Smash Bros. for Nintendo 3DS / Wii U[edit]

In Super Smash Bros. for Wii U, the Metal Box trophy lists Super Mario 64 DS as its other game appearance, even though it (as well as the original game's red and blue ! Blocks) were replaced by ? Blocks in the remake.

This green box will make you the ultimate defensive character, turning you into solid metal for a short time. You won't flinch from enemy attacks, even in midair, and it is much harder to launch you. On the other hand, you fall like a brick. Getting hit will reduce the duration of this item. Whack this box to turn into a metal you! You won't flinch when attacked - even in mid-air - and you'll be harder to launch. Now, the downsides: you'll move slower, fall faster, and recovering when you fall off a stage will be a nightmare. Also, it's only temporary, or lasts until you've taken a certain amount of damage.

Blue indicates it is exclusive to the Wii U version.
