As Mega Lucario, its cream fur becomes longer and its thighs slim down. It develops more spikes on the back of its paws, which have turned crimson. Its aura-sensing appendages grow longer and two of them are tipped in crimson. Its shoulders also possess a spike each. Its aura heightens throughout its body, which formed black markings on its blue fur. Mega Lucario is believed to be the first discovered Mega Evolution.
