'''Boo''' is a recurring character in the Paper Mario series and in the Mario series in general. It is a ghost that, in most cases, is an enemy.
Boos appear several times throughout the story in Paper Mario. most Boos inhabit Boo's Mansion, but several yellow Boos live in Gusty Gulch. All the Boos are led by Lady Bow, who ends up joining Mario on his journey in Chapter 3. In Boo Mansion, several Boos test Mario at the request of Lady Bow. A Boo can be seen guarding a chest with a weight in it, which must be used to progress through the Mansion. Another Boo has a record, which must be used to make the Boo guarding the chest flee. A circle of Boos is also found in the basement guarding the Super Boots.
In Gusty Gulch, the Boos that live there are being eaten by Tubba Blubba. Mario heads off to try a stop Tubba Blubba, and several of the Boos assist him.
Paper Mario: The Thousand-Year Door
In The Thousand-Year Door, Boos inhabit the Creepy Steeple. When Mario first enters the Steeple, only one lonely Boo is found, who forces Mario to open a chest with 200 Boos in it. He will then ask Mario how many boos were in the chest and, if Mario answers correctly, the Boo will give him an Ultra Shroom. If Mario answers incorrectly, he is given a Coin. A lone boo will now appear in the center of the Creepy Steeple and if Mario talks to this Boo, the Boo will ask if Mario is going to be mean to him. If the response is yes then the Boo will simply whine but if the response is no, then the Boo will summon a swarm of other Boos that attempt to kick Mario out of the Mansion over a period of time. Should Mario Spin Hammer spin Hammer enough Boos when they appear close to him, Mario can enter an optional boss fight with the Atomic Boo. Defeating the Atomic Boo awards Mario a badge, then the Steeple area adds Boos placed as normal enemies.
