During a lunch break, on route to Nimbasa City, Ash and co. encounter a Roggenrola when it wrecks Cilan's carefully planned table settings much to his dismay. Ash decides to catch it and notices it has a small electrode on its back. As it turns out Team Rocket is harnessing the power of Roggenrola's Flash Cannon to make a super laser cannon. Will their plan succeed? And after that, will Ash manage to get a new Pokémon?
Cilan has made lunch, but a Roggenrola bounces onto the table, ruining the lunch. The Roggenrola appears very upset, trying to warn the gang of a danger, but Ash thinks it would be good to catch it, so he throws the Pokeball at it, but the Roggenrola frees itself. Ash sends his Oshawott to fight. Ash orders him to use Aqua Jet, but the Roggenrola attacks him, knocking him out. Cilan notices that Roggenrola has a strange thing behind its back.
Ash sends his Tepig and orders it to use Tackle, but Roggenrola is not hurt by the attack, so he uses Flame Chrage to damage Roggenrola. Roggenrola deflects and uses Stone Edge to defeat Tepig. Roggenrola goes away, while Ash, Iris and Cilan go to the Pokémon Center to treat it. Meanwhile, Roggenrola tries to warn the other Pokémon, but they hear a strange noise from the nearby mine. A machine is taking the Roggenrola!
The Pokémon Ash used are treated. A man appears, discussing with Nurse Joy about the pipes - they are fixed, but the water from underground is stirred up. The gang mentions that they saw a Roggenrola, which Joy finds unusual due to Roggenrola living under the earth. The man and the gang go to search the reason for the trouble. They find the Roggenrola, but they also notice that Team Rocket is taking the Roggenrolas to power their machine up. They flee and block the passageway, but Ash gets the Roggenrola before collapsing. Iris brings Excadrill and Cilan his Pansage to dig. They get out of the cave using the tunnel and follow Roggenrola who leades them to the abandoned building.
Team Rocket is surprised they followed them. Nevertheless, Jessie brings her Woobat and it attacks with Air Slash, but Tepig uses Ember to defeat Woobat. The machine grabs the last Roggenrola, but Tepig (whom Ash brought out) uses Ember and the arm is cut. Team Rocket fire the cannon, but Roggenrola counterattacks. Nevertheless, Team Rocket use their cannon, but find it is overloaded, so the Roggenrolas free themselves. James brings his Yamask and it uses Night Shade and Woobat Air Slash. The Roggenrolas use Solar Beam, Tepig Ember and Ash's Pikachu Electro Ball, but Team Rocket depart on their jet packs. After the battle, Nurse Joy checks the Pokémon.
The Roggenrola at the beginning catches Ash's attention and goes outside - it wants a battle. Ash sends his Tepig and the battle begins - Ash orders the Tepig to use Flame Charge, but Roggenrola uses Stone Edge, knocking Tepig out, but not defeating him. Roggenrola is about to use Solar Beam, but Tepig uses Flame Charge to attack Roggenrola. During a moment, both Pokémon try to attack, but Tepig uses its strength to knock Roggenrola out and Ash throws the Pokeball, catching the Roggenrola!
- This is the first time in Unova that Ash turns his hat backwards.
