Leon used his Beheeyem to use its Psychic powers to trick Ash and his friends into thinking that he could grant any wish. After Beheeyem granted Cilan's wish for a bed, Leon stole all of their Pokémon. Officer Jenny was on to his plan and tracked him down, with the help of her Duosion, to a fake resort created by Beheeyem.
However, because Pikachu, Axew, and Meowth were still asleep, Beheeyem's dream still had control over their minds. Once the Pokémon woke up, they managed to escape the dream, but because Meowth kept falling asleep, their escape efforts kept failing. Finally, when Meowth managed to stay awake for a prolonged period of time, he attacked Leon with Fury Swipes, giving Officer Jenny the opportunity to arrest him.
In the original Japanese version, Leon peppers his speech with French phrases.
|Beheeyem befriended Meowth by order of its Trainer so that he could lure Ash and his friends into a trap. It later kidnapped Pikachu, Axew, and Meowth while they were sleeping, replacing them with dolls. It also stole Ash, Iris, and Cilan's on hand Pokémon while they slept.
Beheeyem's only known move is Energy Ball.

- Leon's design and personality are based on the character Iyami from the anime and manga Osomatsu-kun. In the Japanese version, he refers to himself as "me", ends most of his sentences with "zansu" and uses French words and expressions, just like Iyami.
