Cacturneノクタス

AbilityPoison Payback

If this Pokémon is your Active Pokémon and is damaged by an opponent's attack (even if this Pokémon is Knocked Out), the Attacking Pokémon is now Poisoned.

This attack does 50 damage to 1 of your opponent's Pokémon. This damage isn't affected by Weakness, Resistance, or any other effects on that Pokémon.
