Tyranitar

Its body can't be harmed by any sort of attack, so it is very eager to make challenges against enemies.

Raging Crash (10×): This attack does 10 damage for each damage counter on all of your Benched Pokémon.

Earthquake (180): This attack also does 20 damage to each of your Benched Pokémon. (Don't apply Weakness and Resistance for Benched Pokémon.)
