Dark-Type

Dark-type is one of the eighteen Pokémon types, originally introduced in Generation II. Dark-type Pokémon are physically weak to Bug, Fairy, and Fighting-type attacks. Dark-type attacks are physically strong against Ghost and Psychic-type Pokémon. Dark-type Pokémon also have strong defenses against Dark and Ghost-type attacks, and are immune to Psychic-type attacks. Since being introduced in Generation II, some Pokémon introduced in Generation I have had their typings adjusted to Dark-type.
