Emolga first appears looking for Dunsparce in Stompstump Peak. After the player and Emolga rescue Dunsparce, they go back to Post Town, where they help Dunsparce to become friends with Virizion. However, after Dunsparce is coldly rejected and runs away crying, Emolga follows him. (This is the start of Emolga's disliking Virizion). Emolga then hears from Quagsire that Dunsparce went to Desolate Canyon with two Pawniard, he goes to Desolate Canyon to rescue Dunsparce again. He, Dunsparce, the player, their partner, Virizion, Gurdurr, and the Timburr Brothers battle the Pawniard Brothers, two Galvantula, and two Venipede. After defeating them, Emolga, Dunsparce, and Virizion join the player and their partner.
The next day, they are accepted by HAPPI as a team. Emolga suggests "Emolga's Enforcers" as the team name, but no one listens to him, and his suggestion is too long for the character limit anyway.
In Pokémon Super Mystery Dungeon, an Emolga that is likely to be the same is connected to Lillipup, Whiscash, Pachirisu, and Dunsparce, who is also likely to be the same. His request is to help him find Dunsparce.
