On Smogon's Movedex:

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

Effect

Gastro Acid suppresses the target's Ability while it remains in battle.

Gastro Acid fails if the target's Ability is Multitype, Stance Change, Schooling, Comatose, Shields Down, Disguise, RKS System, Battle Bond, Power Construct, Ice Face, Gulp Missile, Quark Drive, or Protosynthesis. Gastro Acid can be reflected with Magic Coat and Magic Bounce (but Gastro Acid will still suppress Magic Bounce if it is not reflected by it, such as if Gastro Acid is used by a Pokémon with Mold Breaker).

Pickup and Honey Gather can still find an item after the battle even if suppressed.

If powered up by a Poisonium Z into Z-Gastro Acid, the user's Speed stat rises one stage.
