Onix

It twists and squirms through the ground. The thunderous roar of its tunneling echoes a long way.

Screech: Until the end of your next turn, if an attack damages the Defending Pokémon (after applying Weakness and Resistance), that attack does 20 more damage to the Defending Pokémon.

Rage (10+): Does 10 damage plus 10 more damage for each damage counter on Onix.
