Lucario is a bipedal dog/wolf/jackal-like Pokémon, with a few raccoon-like characteristics as well. Though it is similar in appearance to Riolu, Lucario has some notable differences, such as having redder eyes. Its fore-paws are black and it has large pointed spikes in place of the oval shaped bumps on Riolu. There is also a third spike protruding in the middle of its chest. Lucario's ears and muzzle are longer in comparison to Riolu but it retains the black "mask" and red eyes.
