Poltergeist

Poltergeists (called Boffins in the PAL versions) are a type of ghost in Luigi's Mansion: Dark Moon. They are orange and possess large brains. While Luigi explores the Gloomy Manor, Professor E. Gadd insists he capture this ghost for research. An Ancient Poltergeist is the mini-boss of Old Clockworks, and a Strong Poltergeist is the mini-boss of Treacherous Mansion. Poltergeists also appear in the bonus mission in Gloomy Manor and the Old Clockworks. The Brain, the final boss encountered in the ScareScraper is the same as the regular Poltergeist except he is much larger and he has 300 HP or more depending on number of players and difficulty.

Poltergeist abilities
The Poltergeist has the power to move objects with telekinesis. When Luigi fights the Poltergeist, it throws books at him while he searches for it. It can even throw books at Luigi while it is being sucked into the Poltergust 5000 to get away. When the Strobulb is used on it while it is carrying a book, it blocks the light using the book. It also plays the piano during the entire battle. In the Old Clockworks bonus mission, instead of books, it throws the bricks placed around the room.

The Brain
The brain is the 'final boss' of The bonus co-op ScareScraper mode. He is fought atop the tower's roof and is a lot bigger. No variations exist [citation needed]

Abilities
The Brain is capable of pushing all Luigis away with a giant force field.

Ghost Container description

 * Poltergeist: These big-headed know-it-alls have swollen brains (and egos) that afford them telekinetic power. Sadly, their sense of humour seems to be underdeveloped.
 * The Brain: This cunning ghost is the most evolved of all the Poltergeists. He awaits ghost hunters who are both brave and smart enough to match his powers.

Campaign

 * Ancient Poltergeist
 * Strong Poltergeist

ScareScraper

 * The Brain

Trivia

 * In the bonus missions of Gloomy Manor and Old Clockworks, if Luigi has to clear a room where a Poltergeist was fought in the campaign, a normal one will appear in the room.
