Storm Drain

 is a Pokémon ability introduced in the fourth generation. It draws in Water attacks to power up the Pokémon.

Description
When a single-target water-type move is used, the Pokémon with Storm Drain draws all water moves towards it, even if it was used by an ally. Originally, the ability would absorb the attacks but, it was updated in the fifth generation, to give the Pokémon a Sp. Attack boost by one stage when hit. Absorb Bulb and Luminous Moss will not trigger while Storm Drain is active. In Triple Battles, Storm Drain cannot draw attacks that are out of range.

If another Pokémon becomes the center of attention via Follow Me or Rage Powder or the target of Spotlight, Water-type moves will be directed to it instead of the Pokémon with Storm Drain.

Mystery Dungeon series
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. Dungeon enemies with Storm Drain can negate the Storm Drain of the player's team.
