Lucario

It's said that no foe can remain invisible to Lucario, since it can detect auras—even those of foes it could not otherwise see.

Avenging Knuckle (30+): If any of your {F} Pokémon were Knocked Out by damage from an attack during your opponent's last turn, this attack does 120 more damage.

Accelerating Stab (120): During your next turn, this Pokémon can't use Accelerating Stab.
