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. Before being pixelated to the Old Clockworks in Mission C-3, Professor E. Gadd mentions that ghosts tend to gain power over time, and that this is the reason the Ancient Poltergeist has his name.

The Ancient Poltergeist looks like a normal Poltergeist except he has a cobalt blue body and a cyan brain, but before battling if Luigi is in the Roundhouse in the level where the Ancient Poltergeist is fought, he appears and is very noisy, and will not stop until Luigi exits the roundhouse or defeats him.

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.
