Boo Mario is a form of Mario that debuted in Super Mario Galaxy. As its name implies, the Boo Mario form is Mario disguised as a Boo, although his hat and face remain respective of his normal form. Boo Luigi, the equivalent form of Luigi, shares the same traits, though with his respective features and a more oval-shaped body. In Super Mario Galaxy, Luigi has a worried look on his face, referencing his fear of ghosts, though he does not in Puzzle & Dragons: Super Mario Bros. Edition.

In Super Mario Galaxy, in order to become Boo Mario, Mario must grab a Boo Mushroom. With this transformation, Mario can turn himself invisible and pass through bars by shaking the Wii Remote, levitate by pressing the A Button button, and descend by holding Nunchuk Z Button. The bars Mario can pass through as Boo Mario are similar to the ones he can pass through with Vanish Cap in Super Mario 64. Mario can also understand the language of the Boos, called Booish, meaning signs written in that language can be understood by him once he transforms. When passing by other Boos, they will be attracted to Mario, signified by a heart popping out of them and chasing him down with a smitten look on their face. This can allow him to make use of them for various purposes. The transformation is lost if Mario takes damage, passes through light, touches water, or touches a Launch Star.

Mario first uses this transformation in the Ghostly Galaxy to rescue Luigi. Because Luigi is afraid of ghosts, he cowers when Mario approaches him in Boo form; therefore, Mario must return to his normal form beforehand. It is also used in Boo's Boneyard Galaxy and Sand Spiral Galaxy.

Super Mario Galaxy 2[edit]

This power-up returns in Super Mario Galaxy 2, in the mission "Haunting the Howling Tower" of Boo Moon Galaxy, where the power-up is very widely used.

Super Smash Bros. series[edit]

In the Super Smash Bros. series, there are a few items of Boo Mario. In Super Smash Bros. for Wii U, there is a trophy of Boo Mario, and it can be obtained at random, like with most other trophies. In Super Smash Bros. Ultimate, Boo Mario appears as a Novice-class support spirit that, when used, increases the fighter's jump height and move speed but makes them easier to launch. The spirit's puppet fighter is an invisible Mario, fought on the Dracula's Castle stage. Boo Mario's core can be combined with Ezlo's core to summon Cappy's spirit, or with a Shy Guy's core to summon Roger the Potted Ghost's spirit.

Puzzle & Dragons: Super Mario Bros. Edition[edit]

Boo Mario reappears in Puzzle & Dragons: Super Mario Bros. Edition, in which he is used as a leader. Luigi's equivalent form, Boo Luigi, also appears in the game. Boo Mario is a Dark and Fire character with average HP, ATK and RCV stats while Boo Luigi is a Dark and Wood character with a high ATK stat and average HP and RCV stats. They are both unlocked by clearing World 4-Tower.

Boo Mario's Skill is Ghost Attack, which turns all of the Orbs in the level into Fire Orbs, Wood Orbs, and Dark Orbs. His Leader Skill is Ghost Power, which raises the player's team's ATK stat by 2.5x after attacking with 3+ attributes at once.

Boo Luigi's Skill is Ghost Trick, which lets the player move Orbs anywhere they want for six seconds. The Skill has no effect in Score Attack. His Leader Skill is Ghost Aura, which has the same effect as Boo Mario's Leader Skill, Ghost Power.

Profiles and statistics[edit]

Super Mario Galaxy[edit]

How to unlock:
Are you afraid of ghosts? Maybe it will help to see the world as they do. Become Boo Mario with a Boo Mushroom, and then explore their world! Shake your Wii Remote to make Boo Mario go through walls. Boo Mario blends in OK, but even as a ghost he keeps his trademark hat. The other Boos don't seem to mind, thankfully. (American English)
Boos are always tricky to deal with, so if you can't beat 'em, join 'em! All you need to do is grab a Boo Mushroom, and you'll become a Boo, letting you turn invisible, slip straight through walls and even speak Booish! You'd think Boos wouldn't fall for it, what with that trademark cap still firmly on top of your head...but luckily, they do. (British English)
