With sufficient training, a Lucario can read auras to understand how living beings are feeling from more than half a mile (1 kilometer) away. Lucario can study auras to predict the movements of its opponents and track their quarry. It has developed four black appendages that hang down from its head, which rise when Lucario reads or manipulates aura, a special energy that it senses. It stands on its toes rather than on its entire foot. It has a medium-length tail of the same blue color as well.
It possesses cream-colored fur on its torso and blue fur on its thighs that resemble shorts. When its mouth is open, two pairs of pointed teeth, one in the upper jaw and one in the lower, can be seen. It possesses a short, round spike on the back of each forepaw, in addition to a third on its chest. Lucario is a bipedal, canine-like Pokémon with predominantly blue and black fur.
