Ghost-type Pokémon are a category of creatures in the Pokémon franchise known for their supernatural abilities. They often have characteristics associated with spirits, such as invisibility or the ability to pass through walls. Ghost-types are typically weak against Dark-type and Ghost-type moves but are strong against Psychic-type and Fighting-type Pokémon. In battles, Ghost-type Pokémon can use unique moves like Shadow Ball and Phantom Force, which can deal significant damage to opponents. Many Ghost-types also possess abilities that allow them to evade attacks or inflict status conditions, making them strategic choices in competitive play.
