The Dark type (Japanese: あくタイプ Evil type) is one of the eighteen types. Notable Trainers who specialize in Dark-type Pokémon are Karen of the Indigo Plateau Elite Four, Sidney of the Hoenn Elite Four, and Grimsley of the Unova Elite Four. Notably, the Dark type is the only type that has never had a Pokémon Gym specialize in it, although it is a recurrent type used by villainous teams and Elite Four members. Prior to changes in Generation IV, all damaging Dark-type moves were special, but they may now also be physical depending on the attack.
The Dark type was introduced in Generation II, along with the Steel type.
