Boo Mario

Template:Form-infobox Boo Mario is a form of Mario that appears in the game 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.

In order to become Boo Mario, Mario must grab a Boo Mushroom. With this transformation, Mario can turn himself invisible and pass through certain walls and gates by shaking the Wii Remote and levitate by pressing the button. The walls 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 bill boards written in that language can be understood by him once he transforms. His Boo form also attracts other Boos, causing them to follow him around and 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. Boo Luigi also appeared in this level, which as the name implies, is the equivalent form for Luigi should the player play as him.

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. This power-up does appear in Super Mario Galaxy 2, but in only one galaxy: the Boo Moon Galaxy in the mission "Haunting the Howling Tower", where the power-up is very widely used.

Boo Mario, as well as Luigi's equivalent form, also appeared in Puzzle & Dragons: Super Mario Bros. Edition .

Aside from the games, Boo Mario also appeared in animated sticker where it shows Mario defeated, with Boo Mario emerging from him as if Mario had died.

In the deep recesses of the Ghostly Galaxy, strange and frightening spirits are after Mario. To help Mario navigate this scary place, he can grab a Boo Mushroom and power up to become Boo Mario! This allows him to become invisible, float like a Boo, and pass through walls.

Boo Mario		Wii Super Mario Galaxy (11/2007) Wii Super Mario Galaxy 2 (05/2010)	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.	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.
