On Smogon's Movedex: Generation IV Generation V Generation VI Generation VII Generation VIII Generation IX

Gastro Acid (Japanese: いえき Gastric Juice) is a non-damaging Template:Type2 move introduced in Generation IV.

Effect

Gastro Acid cancels the target's in-battle ability. Therefore, the target's ability will be ignored until it is switched out, even if it Transforms. It does not affect abilities that only have an effect outside of battle, such as Illuminate. Furthermore, Gastro Acid does not negate abilities that have an immediate effect at the start of the battle, such as Drizzle, because the ability will activate before Gastro Acid can even be used. Gastro Acid cannot be used to deactivate the ability of a Plate-holding Arceus.

Trivia

• Despite being introduced in Generation IV, no fourth generation Pokémon could learn Gastro Acid until the release of Platinum. Even via the Platinum move tutor, only one Generation IV Pokémon can learn this move, Carnivine. Furthermore, in Generation V, Carnivine could no longer learn the move, though it may have it if transferred from Generation IV.
