The user either is or can transform into a Poltergeist, ("noisy ghost") a manifestation of an invisible but noisy, disruptive or destructive entity. Unlike regular ghosts, Poltergeists haunt a particular person instead of a specific location. Poltergeists have been known to be a troublesome, destroying things for no apparent cause. Reports also include inanimate objects being picked up and thrown as if by an invisible person; noises such as knocking, rapping, or even human voices; and petty physical attacks on human beings, such as pinching, biting, and hitting.
