Riolu is a small, blue, canine Pokémon. It has black legs and torso, a blue tail, and a yellow collar. It has rounded bumps on the backs of its forepaws. It has a black "mask" and red eyes. It stands on its toes instead of its entire foot. It is sensitive to a special type of energy called Aura; however, It does not have the ability to fully use these powers, although it can still emanate these waves to communicate and sense them, albeit only in ripples. Like almost all Fighting-type Pokémon, Riolu naturally has superhuman strength, stamina, and endurance and is capable of making long journeys on foot in a short amount of time. It is a playful, energetic, and loyal Pokémon.
