Ancient Poltergeist

Ancient Poltergeist (known as Boffin Elder in PAL versions) 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 Tower Gate, only to have it being taken away by the Ancient Poltergeist. After defeating him in the next mission, 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. The Ancient Poltergeist can create a dust devil in the middle of the arena, by hiding in the turntable, which sucks Luigi towards it as well as throwing and detonating bombs from nearby crates. The Ancient Poltergeist will also summon Sneakers to prevent Luigi from capturing it.
