A Pokémon with the Storm Drain Ability will have Water-Type attacks drawn to it in a Double Battle, including Hidden Power Water in Generation V. Other effects were added to Storm Drain in the fifth generation: an immunity to Water-Type attacks and an increase in the Special Attack of the Ability's user by one stage, even in a 1-on-1 battle.
Storm Drain cannot redirect moves that strike multiple Pokémon, such as Muddy Water or Surf. Additionally, the move Follow Me will redirect a Water-Type attack away from a Pokémon that has the Storm Drain Ability.
Storm Drain doesn't have an effect in the overworld.
