Weiss' Zangoose is a member of Plasma Gang who follows the commands of Weiss. When N managed to rescue Braviary, Weiss' Zangoose and Schwarz's Seviper were summoned out to intimidate N. Plasma Gang realized that N had deceived them, so they intended to hurt him with Weiss' Zangoose and Schwarz's Seviper. Both the Pokémon seemed to hesitate a bit when N said he could free them as well from being abused by Plasma Gang but they were then forced to follow commands and attack N. N vowed that as long as Pokémon like Weiss' Zangoose and Schwarz's Seviper were being abused in the world by thugs, he'd continue fighting to free them. He wanted Weiss' Zangoose and Schwarz's Seviper live happily but at that time he wasn't able to help them.

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