Schwarz is a Team Plasma Grunt. Schwarz and Weiss are team members that often work together on missions. While transporting a captured Braviary to be used as research material, N (Natural Harmonia Gropius) managed to break into the truck they were driving at rescue Braviary.

The two followed N (Natural Harmonia Gropius) to a nearby Pokémon Center as they had attached a tracking device to Braviary. They decided to try and reclaim Braviary by breaking into the Pokémon Center. Ash Ketchum and his friends were there and proved to be a distraction after they realized that Plasma Gang was attacking the Pokémon Center. They followed N (Natural Harmonia Gropius) who had the tracking device on him now while Ash Ketchum took Braviary to a save location where it could get away. Realizing that Schwarz and Weiss had caught up with N (Natural Harmonia Gropius), Braviary returned to help N (Natural Harmonia Gropius).

Schwarz's Seviper and Weiss' Zangoose were sent out to battle against Pikachu and Iris' Excadrill. Iris' Excadrill managed to knock out Schwarz's Seviper while Pikachu almost finished off Weiss' Zangoose but Braviary came to Pikachu's rescue.

Realizing that they were now defeated, Schwarz and Weiss decided to retreat as they were unable to reclaim Braviary.
