Stephan's Blitzle battled Ash's Oshawott in a field near Raimon City. Stephan initially was surprised that Ash Ketchum used a Water type against his Blitzle which is an Electric type but he soon realized that Ash's Oshawott uses it's Scallsword as a defense to reflect electric attacks. Stephan's Blitzle used other attacks to counter Ash's Oshawott's electric defense and its Double Kick managed to knock Ash's Oshawott's Scallsword out of its hands and far away into the forest. Ash's Oshawott quickly stopped the battle to go after its Scallsword.

Later on, Stephan's Blitzle battled once again with Ash's Oshawott even though it didn't have its Scallsword. Cilan's Dwebble fashioned a new Scallsword for Ash's Oshawott out a rock but during the battle, Stephan's Blitzle's Double Kick managed to destroy it leaving Ash's Oshawott somewhat defenseless. Even though Ash's Oshawott had lost its Scallsword, Stephan's Blitzle still ended up loosing to Ash's Oshawott after the two of them crashed into a big rock. Stephan's Blitzle was knocked out but Ash's Oshawott managed to get up.

Stephan's Zebstrika was revealed at the registration for the Don Battle Tournament in Raimon Town. Stephan was riding it when he met Ash Ketchum and his friends. Stephan's Blitzle evolved into Stephan's Zebstrika as Stephan confirmed to Ash Ketchum that it had evolved during the time between BW41 and their last meeting in BW31.
