Dark

The Dark type (Japanese: あくタイプ Evil type) is one of the eighteen types. It was introduced in Generation II, along with the Steel type. As well as introducing new Pokémon and moves with the Dark type, one move was changed to be the Dark type. Dark-type moves are super-effective against Ghost- and Psychic-type Pokémon, while Dark-type Pokémon are weak to Bug-, Fairy-, and Fighting-type moves.
