After the events from the last episode, the Sunglasses Krokorok has returned once again to challenge Ash to a battle bent on defeating his rival, Pikachu after he followed them for a long time from Nimbasa Town, Nimbasa City, Driftveil City, and Chargestone Cave. During a rival battle, Krokorok got blasted off while Pikachu is knocked for a loop and is seen rolling into the next town. Pikachu is then found by a little boy name Nick who apparently had no confidence in himself. Ash and co. run into Krokorok again and find Pikachu with Nick. He explains that his friend Glen started something every time always saying the word "Let's Battle!". Meanwhile Glen and Shaun are having a Pokémon battle just for fun which causes Glen to start a fight with Shaun when Blitzle dodged Patrat's Tackle. Can Ash help this budding young trainer how to battle right so he could battle his friends with his Pikachu? And will they receive help from an unexpected source?
