Riley is a character that first appears in Iron Island who can join the player during an event in Diamond, Pearl and Platinum. He asks the player to help him investigate the cause of the sudden disturbance of the Pokémon inside Iron Island. After defeating two Team Galactic Grunts who happened to be in the cave, he will give the player a Riolu egg. He can later be found in Sinnoh's Battle Tower competing against the player. All of his Pokémon are versed in the Attack statistic.
