Riley is a character appearing in Pokémon the Series: Diamond and Pearl.


Riley's appearance is similar to Sir Aaron. He wears a blue dress coat and a black shirt with a crest similar to Sir Aaron's gloves. His hat is an introverted version of Sir Aaron's with the emblem omitted. He wears brown pants and black dress shoes.


Riley is a caring individual who considers Iron Island to be a home for his soul. He doesn't approve anyone threatening the peace of Iron Island and its inhabitants.


Pokémon the Series: Diamond and Pearl

Due to the strange behavior of the Steel-type Pokémon on Iron Island, Riley decided to investigate it with the help of his Lucario. He found Ash trying to stop an Aggron, and saved him from being attacked by Flash Cannon, whereas Lucario used Close Combat to defeat Aggron. He had his Lucario use its aura to sense the source of frequency, which turned Steel-type Pokémon berserk. He wanted to escort the heroes to safety, but they were more inclined to help Riley. As Lucario believed the same, Riley permitted them to do so, but reminded that they had to battle berserk Pokémon. Eventually, the group found the source of the frequency being emitted by Team Galactic, who were trying to open some ruins. As Mars placed an artifact in the ruins, a beam was shot to Mt. Coronet, but this only overpowered Lucario to turn on Riley and form Aura Sphere to attack them.[1]

Riley used its own aura, stopping Lucario's Aura Sphere. Riley pointed out that Lucario was tainted, too, by the frequency from Iron Island. Riley went to call Lucario back into its Poké Ball, but Lucario was fast enough to destroy the Ball with a Bone Rush. Ash and Brock held Lucario down, and Pikachu used Thunderbolt - which electrocuted Ash and Brock, too - to snap Lucario out of its state. Lucario went to disable the source, to which it was attacked by Mars' Pokémon. The heroes went to disable Team Galactic's machine, to which Pikachu used Thunderbolt to destroy it.

However, Team Galactic released bombs around the island before retreating. Since neither Lucario nor Riley could've counted how many bombs there were on the island, to which they attempted to dismantle some of them. Since that failed, Mars triggered the explosion, but Riley and Lucario used their aura to contain the explosion into a bubble, then release it in mid-air to prevent the island from being destroyed. With the matter settled, Professor Carolina and her team arrived, studying the island a bit and asking Riley's help around the island.[2]
