Riolu is a small, blue, canine Pokémon. It features a black torso and legs, a blue tail, and a yellow collar. This Pokémon has rounded bumps on the backs of its forepaws. Its face is adorned with a black "mask" and striking red eyes. Riolu stands on its toes rather than its whole foot. It possesses a sensitivity to a unique form of energy known as Aura; however, it cannot fully harness these powers. Nonetheless, it can emit and detect these waves for communication and sensing, though only in slight ripples. Two black appendages hang from its head, rising when Riolu reads or manipulates aura. Interestingly, Riolu can sense and react to Aura even before hatching. When frightened or sad, the aura emitted by Riolu intensifies.
Like many Fighting-type Pokémon, Riolu naturally exhibits superhuman strength, stamina, and endurance. It can cover long distances on foot swiftly. This Pokémon is playful, energetic, and loyal. Riolu has the ability to read human minds to determine if they are pure of heart.
