Boo
Boos are the ghosts in Super Mario games. They are shy creatures; they hide and become invisible whenever Mario is facing them. In some games, boos take on a more active role. In Super Mario 64, Big Boo's Haunt was the 5th level. In Mario Tennis and Mario Golf, Boo was a playable character. In the Mario Party series, Boo originally would steal coins or stars from characters, but by the fifth installment Boo was a playable character.
In Super Smash Bros. Melee
Trophy description
These shy spirits inhabit Mario's world and have been known to vanish or freeze when met face-to-face. In recent years, they seem to have overcome their fears in order to pursue tennis and other social activities. They usually appear in groups and fly in formation. From time to time, giant Boos make surprise appearances.
Game: Super Mario Bros. 3 [02/90]
In Super Smash Bros. Brawl
As a stage element
Boos briefly appear from the rubble of the Luigi's Mansion stage after the mansion collapses.
As a sticker
Boo appears as a sticker in Super Smash Bros. Brawl. He is in his Mario Tennis role, complete with a racket. When applied to a trophy in the Subspace Emissary, the sticker increases the damage done by thrown items. The sticker is extremely easy to get, as every time the sandbag is hit more than 900 ft. in the Home Run Contest, one Boo Sticker is obtained.
Trophy description
A bashful ghost who draws near when your back is turned but shyly stops and disappears when you face it. Boos have been seen recently in activities like baseball and tennis, so it's thought that they may have conquered their fear of humans. Boos are also characterized by having a variety of different weaknesses between forms.
