Metal Mario (form)

Metal Mario (called Metal Power for Super Mario 64 DS ) is a powered up form of Mario that first appeared in the game Super Mario 64. Metal Mario is tougher, stronger, virtually invincible, and can be hurt only by long falls. This form is acquired by picking up the Metal Cap from green ! Blocks, with the use of a Metal Mushroom Orb or a Metal Box.

The Metal form is later granted to other characters, though the form itself acts the same.

Super Mario 64
When Mario first encounters the Metal Cap in Cavern of the Metal Cap in Super Mario 64, he becomes Metal Mario, a living embodiment of metal. In this form, Mario is invincible (although he can still take falling damage) and can destroy enemies just by running into them. Metal Mario is also very heavy, and as such, can withstand strong winds, underwater currents, and can walk on the bottom of bodies of water. In addition, he doesn't need to breathe, meaning he can stay underwater without worrying about air until the metal power runs out. Despite being heavy, Metal Mario still retains all his physical speed as well his athletic jumping abilities, but will sink in quicksand faster.

Metal Mario can combine his Metal Cap with the Vanish Cap to become, which will enable him to go through certain walls while maintaining his metal form's strengths and weaknesses.

Super Mario 64 DS
In the remake of Super Mario 64 for the Nintendo DS, Super Mario 64 DS, only Wario could turn metallic and become Metal Wario by using a Power Flower. He is able to walk on Lava and Freezing Water, though after a while he begins to sink and if he goes below the surface he will lose a life. Metal Wario's other abilities and vulnerabilities are the same as Metal Mario's.

Dr. Mario 64
At one point in Dr. Mario 64, Dr. Mario accidentally eats some Megavitamins and turns into a Metal Mario form. This metallic Dr. Mario also appears as a separate, playable character.

Super Smash Bros. series
A Metal Mario character appeared in the original Super Smash Bros. as a boss. The sequel, Super Smash Bros. Melee also featured this permanently metal alter-ego of Mario as well as a separate Luigi character as bosses.

As of Super Smash Bros. Melee, players can pick up the Metal Box as an item, and gain metal forms for a limited time, all boasting the same attributes as the non-playable Metal Mario: namely, being heavier and silent, except for clanging metal noises made when they move. This metal form can also be used as a setting in Special Brawl of Super Smash Bros. Brawl and in Special Smash in Super Smash Bros. for Wii U.

In Classic Mode of Super Smash Bros. Melee and Super Smash Bros. Brawl, a character in metal form will always be one of the selected challengers. In Super Smash Bros. Melee, this metal character will always appear at Level 10, whereas in Super Smash Bros. Brawl, one will appear at random anywhere from Levels 6 to 10. In Super Smash Bros. for Wii U, when the player chooses a battle in the first five rounds, one or more opponents might suddenly be replaced by an intruder, marked by a glowing yellow trophy base, even in a team battle. Intruders are always in a permanent Giant or Metal state, but are guaranteed to be carrying a prize of some kind for victory.

Additionally, the Metal Box is also available as a red item in Smash Tour, giving players the ability to start a battle in metal form. Crazy Orders may also feature a Metal Battle as a potential order option.

In Smash Run of Super Smash Bros. for Nintendo 3DS, alongside the Fighting Mii Team, normal-sized and giant Metal versions of the player's character may appear in the game's Multi-Man Smash Final Battle as opponents.

Mario Party series
The metal form also appears in Mario Party 6 and Mario Party 7 when one of the playable characters uses a Metal Mushroom Orb on him- or herself to avoid traps. Also, when a player gets a Cursed Mushroom Panel, Bowser makes a brief reference to Metal Mario, by saying, "Answer quickly or your bonus points will fall like a Metal Mario off an airship!"

Mario Strikers Charged
It appears that Mario can become Metal Mario in Mario Strikers Charged when he performs his Mega Strike, since the Mega Strike's name is called "Fiery Metal Mario".

Puzzle & Dragons: Super Mario Bros. Edition
Metal Mario appears in Puzzle & Dragons: Super Mario Bros. Edition as a Leader, available with the game's digital update to version 2.0, unlocked after earning an S rank or higher in Course 3 of the Fixed Challenges in Score Attack. Metal Mario is a Dark/Dark attribute teammate with an HP rating of 4/6, an ATK rating of 5/6 and RCV rating of 2/6. Metal Mario's Skill, Metal Walk, changes Water Orbs on the Orb field to Dark Orbs, while his Leader Skill, Metal Shine, raises the ATK of the entire team by 3x if the player clears two Dark combos, or by 4x for three Dark combos or more. Metal Mario uses Fruit and Rare Fruit to raise his Skill Levels.

Metal Luigi also appears as a Leader, unlocked after earning an S rank or higher in Course 3 of the Free Challenges in Score Attack. Metal Luigi is also a Dark/Dark attribute teammate, having an HP rating of 3/6, an ATK rating of 5/6 and RCV rating of 3/6. Metal Luigi's Skill, Metal Dash, changes Light Orbs on the Orb field to Dark Orbs. Metal Luigi shares the same Leader Skill and Skill Up requirements as Metal Mario.

Trivia

 * In an interview with Shigeru Miyamoto in Nintendo Power's Mario Mania Player's Guide published in 1991, Miyamoto reportedly said: "Who knows what Mario will look like in the future? Maybe he'll wear metallic clothes!" The Metal Mario form's first appearance was in 1996, five years later.
 * In Super Mario 64, the music that plays when the player is Metal Mario is a remix of the Starman's theme from Super Mario Bros.
 * In the Super Smash Bros. series, anyone who turns into a metal form loses the ability to vocalise (except Samus Aran, Captain Olimar, R.O.B., Mr. Game & Watch, Mega Man, Pac-Man, the Villager, Duck Hunt, and the Mii Fighters, all of whom technically don't vocalise anyway, although they make their beeping and mechanical noises instead).
 * An exception to this is Sonic, who doesn't have his voice changed when he initiates his Final Smash.
 * Characters in the Mario Party series retain their ability to vocalise, and they do not have their voices filtered.
 * While the Metal Mario form itself is not in the game, Silver Luigi in New Super Mario Bros. 2 looks very similar to Metal Mario, right down to the metallic finish.
