Stephan appeared in BW031 and he had a battle with Ash's Oshawott. In the first battle he won, but in the second one he wasn't so lucky. He later reappeared in BW041 in the Club Battle Tournament. He lost to Iris and her Emolga in the quarter-finals. A running gag is that nobody can pronounce his name properly and he keeps complaining about it. He appeared again in BW071 to compete in the Bell of Wishes Festival Contest and won. He accompanied Ash and co. to the next town for the Donamite Battle Competition. Stephan won the tournament after beating Masaomi and his Throh.

- Stephan should also have a third Pokémon, because he participated in the Club Battle Tournament, which requires three Pokémon for entry.
- Stephan seems to be a sort of replacement to Team Rocket's Butch. This is due to the fact that no one pronounces either names right.
