From Bulbapedia, the community-driven Pokémon encyclopedia.
The Aura Sphere Riolu (Japanese: はどうだん リオル Wave Bomb Riolu) is a special Aura Sphere-using Riolu that appeared into two media, in both the Pokémon game Pokémon Ranger: Shadows of Almia and the episodes Pokémon Ranger and the Kidnapped Riolu! Part One and Part Two of the Diamond & Pearl series in the anime, starring in those episodes as the main Pokémon.
History
In the games
This special Riolu was befriended by Kyle before moving to Almia (which was revealed later in the Ranger Net mission Rescue Kidnapped Riolu), and he seemed obsessed with Riolu beforehand. In the mission Rescue Kidnapped Riolu, Riolu should be saved from Team Dim Sun, as they will use it as weapon to restore them. It seems to have a connection with Kyle using Aura, since he used it to target to Team Dim Suns' hiding place when the lights went off. The Riolu is later captured by the player Kellyn and can be sent to Pokémon Diamond, Pearl, or Platinum.
In Diamond, Pearl or Platinum
Riolu is obtained as a Mystery Gift, knowing Aura Sphere. Notably, his OT is Kyle, the character he befriended in Shadows of Almia.
In the anime
Riolu used to live in the Lucario Kingdom. While it was being tested in a lab, J's henchmen broke in and stole Riolu. Fortunately, it escaped, and tried to attack Ash, and Kellyn blocked it using his Vatonage Styler, and then, on the way J attacked them in an attempt to take Riolu. However Ash escaped with it, however J started a forest fire, and out Riolu in a case. However, it was later freed by Ash, using an Aura Sphere so powerful to stop an Aggron's Hyper Beam. He seemed to have a little Wooden Riolu toy. This episode was inspired by the Ranger Net mission (clearly explained by Kellyn's appearance). He was later moved back to the Lucario Kingdom.
Moves used
Riolu, throughout the two episodes used only Aura Sphere.
