Wes was formerly a member of an organization called Team Snagem, which had obtained a machine that allowed the user to "snag" another Trainer's Pokémon as though it were wild. Another team, Cipher, was responsible for corrupting the hearts of Pokémon and giving them to Trainers. With the help of a young girl named Rui, Wes was able to find the Pokémon whose hearts were sealed and surrounded by a purple aura and use the Snag Machine to rescue Shadow Pokémon and restore them to normal.
