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 Don 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 Montgomery and his Throh.
He made an appearance in BW043 and battled Iris' Emolga at the quarter-finals of the Don Battle Tournament. During the battle Sawk showed the extent of his power by stopping Emolga's Attract with Close Combat. However, Emolga's Static paralyzed him resulting in her victory. It reappeared in BW071 and, like Stephan in the cosplay contest, it dressed up as Nurse Joy's Audino. Sawk's Moves: Close Combat, Bulk Up and Double Kick.
