Since Generation VI, it is weak to Fairy types. It was also given to make the Fighting type and Bug type more dominant due to their downfall to Psychic types in Generation I. The Dark type was added in Generation II to counteract the Psychic type's dominance in Generation I, by being completely immune to it and able to hit Psychic types super-effectively.

The Dark type (あくタイプ Aku taipu) is one of the eighteen Pokémon elemental types.
