Pokemon's Ghost-types are perfect for Halloween. From more recent additions to the Pokedex like Spectrier to old favorites like Gengar, it's easy for fans to associate these spooky critters with the holiday. Game Freak has almost encouraged players by making other Ghost-types that fit Halloween like Pumpkaboo, so it's fitting that a new Ghost-type for Pokemon Scarlet and Violet was announced before October ended. Fans now have a new adorable ghost dog to love known as Greavard.
