Max Darkness is a Dark-type Max Move introduced in Pokémon Sword and Shield. It is a Dynamax move that replaces any Dark-type move when a Pokémon is Dynamaxed. Max Darkness does not have a fixed power or accuracy since it depends on the base move it overrides, varying between 100 to 160 power based on the move. This move also has the added effect of lowering the Special Defense of the target by one stage. Max Darkness is notable for its strategic use in lowering the opponent's defenses, making it a valuable move in both offensive and supportive roles during Dynamax battles.
