Storm Drain (Japanese: よびみず Pump Preparation) is an ability introduced in Generation IV that draws all Water attacks to the Pokémon. Four Pokémon have this ability, all of them Water-type. In a double battle, a Pokémon with this ability will force all water attacks to exclusively strike it; this ability is rendered ineffective in a single battle. Unlike Lightningrod, since no types are immune to Water, the four Pokémon with this ability take half or full damage from Water attacks, rendering it less useful in general than a Ground-type with Lightningrod. Having a Pokémon with the ability Storm Drain at the front of your party will also cause the chances of encountering a Water wild Pokémon to increase.
