Subway Boss Emmet (anime)

Subway Boss Emmet is a citizen of Nimbasa City.

Season 14: Black & White
Emmet, as well as his brother, Ingo, took care of the Nimbasa City's Underground. Troubles started arising when Jessie and James started to use their own train and test it in the Nimbasa Underground. Emmet and Ingo tried to investigate, but failed. They soon meet Cilan, their Metro Connoiseur friend, as well as Ash and Iris. After Meowth started the heist by throwing Poké Balls, including Pikachu and Axew, Ingo and Emmet reached the Underground HQ and tried to solve this mess. However, Team Rocket started spouting up many decoy trains, shocking the Subway Bosses, since they couldn't do anything to prevent that. Ingo and Emmet boarded onto the cart, powered by Emmet's Eelektross's Discharge, and managed to take the heroes along to chase Team Rocket's train. Emmet's Eelektross gave chase to Team Rocket's train, allowing Ingo to have the heroes board the enemy train on. In the end, after the trouble was over, Emmet wished Ash luck in his Gym Battle against Elesa.

Season 15: BW Rival Destinies
After hearing Erina's Axew got lost, the Subway Bosses managed to locate Ash and Iris and re-unite them with Cilan and Erina, thus having Axew returned to her trainer. Though Cilan didn't manage to retrieve one last stamp, Erina gave him the stamp and he challenged the Subway Bosses to a tag battle, with Ash as his partner. Emmet proved his teamwork with Ingo and managed to defeat Ash and Cilan.
