Misty's Tentacruel

Pokémon Power: Flee If an attack does damage to Misty's Tentacruel while it's your Active Pokémon, you may switch it with 1 of your Benched Pokémon, which prevents all other effects of that attack on Misty's Tentacruel. This power can't be used if Misty's Tentacruel is already Asleep, Confused, or Paralyzed.
