Wes (Japanese: レオ Leo) is a young man who lives in the Orre region of the world. He is the protagonist of Pokémon Colosseum.
Wes has apparently been with his Pokémon, Umbreon and Espeon, for years, possibly since childhood. Wes joins Team Snagem for unclear reasons and presumably leaves once he becomes disgusted with their actions.
Before he does, he plants a bomb to completely destroy Team Snagem's headquarters and steals the portable version of the Snag Machine - a device that can turn Poké * into Snag * - which can be used to catch Pokémon already owned by other Trainers. In the process Wes reveals the hidden base to the police of Orre.
Equipped with this device, Wes wanders around until he rescues Rui from some kidnappers in Phenac City. Using his very high-tech hovering motorcycle to travel around Orre, Wes and Rui set off to uncover the conspiracy behind Cipher, Team Snagem, and Shadow Pokémon.
Wes's actions eventually attract the attention of both Ho-Oh and Celebi, indicating that he must care deeply for all Pokémon.
