Corrosive Gas is a Poison-type move with no base power and perfect accuracy. When used, it targets an adjacent Pokémon and removes the target's held item, unless the target has the Sticky Hold Ability or is behind a substitute. Corrosive Gas is unique because it can affect both grounded and airborne Pokémon, making it versatile in battle. It is useful in disrupting strategies that rely on held items, such as Choice items, Berries, or Eviolite, and can significantly alter the dynamics of a match.
