Barret first appeared with two other grunts looking for N under Ghetsis's orders. He was able to find him when he used a locator inside his briefcase and deduced the hidden location. With N found, Barret started attacking the Pokémon with Magnezone but Anthea and Concordia's Gardevoir and Gothitelle blocked the attacks with Protect. Ash decided to deal with Barret while Iris and Cilan handled the other two. While Cilan's Pansage attacked Magnezone, a collision of Bullet Seed and Magnet Bomb caused an explosion. The seeds went flying in which Pignite's snout became stuck by one of the stray seeds. With Barret's Magnezone defeated, a fog occured which prevented Barret from seeing anything and allowed Ash and his friends to get away. Barret became upset about not being able to capture N and left the forest.
In Meowth, Colress and Team Rivalry!, when Team Rocket hacked into Team Plasma's data, the trio imprisoned Barret, Aldith and the grunts while they were running off with the data. However, Brad had Magnezone confuse some nearby Pokémon to break them free.
In Ash and N: A Clash of Ideals!, he battled with Cedric Juniper's assistants' Pokémon with Colress's aid.
In Team Plasma and the Awakening Ceremony!, he tried to stop Ash and his Pokémon from saving the others using the ones Colress had managed to control with his machine.
He was arrested alongside Ghetsis, Colress, Aldith and the other Grunts in BW122 by Looker, after Ghetsis' plan of using Reshiram failed.
