Storm Drain (ability)

Storm Drain (Japanese: よびみず Pump Priming) is an Ability introduced in Generation IV. Seven Pokémon have this Ability, four of which are Water-type and the remaining being Grass-type.

Effect

In battle

Generation IV

Storm Drain is only effective in double battles, and a Pokémon with this Ability will force all single-target Water-type attacks used by other Pokémon to exclusively strike it, including those used by allies. Water-type moves will hit the Storm Drain user with 100% accuracy, even in a single battle. Storm Drain cannot redirect Surf or Muddy Water, as they target multiple Pokémon. Storm Drain cannot redirect a Water-type Hidden Power.

If Follow Me is used while a Water-type move is being used, and a Pokémon with Storm Drain is active, the Pokémon using Follow Me is hit instead.

Generation V

Along with its previous effects, Storm Drain also gives Pokémon immunity to all Water-type attacks and raises the Pokémon's Special Attack whenever they are hit by one (even in normal battles). It will also draw in a Hidden Power of the Water-type.

Storm Drain does not draw in Soak in a double battle.

Outside of battle

Storm Drain has no effect outside of battle.

Pokémon Mystery Dungeon

In Explorers of Time and Explorers of Darkness, a Pokémon with Storm Drain draws in all enemy Water-type attacks on the floor, and their damage/effect is completely neutralized.

Trivia

• Unlike with Lightningrod, no types are immune to Water, therefore, in Generation IV, the four Pokémon with this Ability took half or full damage from Water attacks, rendering it less useful in general than a Ground-type with Lightningrod.
