Ancient Poltergeist

Ancient Poltergeist is a mini-boss Luigi fights in Luigi's Mansion: Dark Moon. After exploring the Tomb, Luigi finds the minute hand for the clock in the Clock Gate, only to have it being taken away by the Ancient Poltergeist. After defeating him, Luigi gets the minute hand back.

The Ancient Poltergeist looks like a normal Poltergeist except he has a blue body and a blue brain.

Abilities
The Ancient Poltergeist basically attacks like a normal Poltergeist. He can use his telekinetic powers to launch bricks at Luigi. He can create a large, sandy tornado in the middle of the arena which sucks Luigi towards it as well as detonating any bombs nearby. Instead of creating clones of himself like Poltergeist, the Ancient Poltergeist will summon Sneakers to distract Luigi.
