Sharpedo

If Sharpedo is your Active Pokémon and is damaged by an opponent's attack (even if Sharpedo is Knocked Out), put 2 damage counters on the Attacking Pokémon.

If the Defending Pokémon has 2 or more damage counters on it, this attack does 60 damage plus 20 more damage. This attack damage isn't affected by Weakness, Resistance, Poké-Powers, Poké-Bodies, or any other effects on that Pokémon.
