Once during your turn (before your attack), if this Pokémon is in your discard pile, you may put it onto your Bench. If you do, put 1 damage counter on 2 of your opponent's Benched Pokémon.
Original Korean copies of this card incorrectly state that Giratina's Ability puts 1 damage counter on 2 of your opponent's Active Pokémon, instead of their Benched Pokémon.
