Acid (Japanese: ようかいえき Corrosive Liquid) is a damage-dealing Poison-type move introduced in Generation I.

Effect

Generation I

Acid inflicts damage and has a 33.2% chance of lowering the target's Defense stat by one stage.

When used by an in-game opponent, there is an additional chance of 25% for the effect to fail (resulting in an effective chance of 24.9%).

Generation II

Acid now has a 10% chance of lowering the target's Defense stat by one stage.

When used by an in-game opponent, there is still an additional chance of 25% for the effect to fail (resulting in an effective chance of 7.5%). This does not apply when Lock-On or Mind Reader are in effect, nor in the Battle Tower.

Generation III

Acid inflicts damage to all adjacent opponents.

Acid's effect no longer has an additional chance to fail when used by an in-game opponent.

Generation IV onwards

Acid now has a 10% chance of lowering the target's Special Defense by one stage instead.

In Triple Battles, Acid only targets adjacent opponents.

Trivia

Acid, as a Poison-type move, normally has no effect on Steel-type Pokémon, despite the fact that real-life acids react very strongly with most metals.
