Poltergeist is a Ghost-type move with 110 power and 90% accuracy. It requires the target to be holding an item for the move to work. If the target isn't holding an item, the move will fail. Due to its high power, it is one of the most potent Ghost-type attacks in the game. Poltergeist not only deals significant damage but also thematically involves the haunting of the target by its own held item, adding a unique strategic layer. It was introduced in Generation VIII and quickly became a staple for many Ghost-type Pokémon in competitive play, thanks to its balance of power and the added layer of item manipulation.
