The episode begins with a recap of Ash's gym battle against Roxie, with her Koffing taking out two of his Pokémon before getting knocked out by his Leavanny. However, Roxie has sent out Scolipede to follow up, who instantly struck Leavanny with Toxic. Badly poisoned and nearly unable to stand, Leavanny fires an Energy Ball which Scolipede dodges, and Roxie orders a Rock Tomb, trapping Leavanny in rocks. Scolipede launches a Sludge Bomb that hits Leavanny head-on, fainting it.
Billy Jo taunts Ash having only half his team left, but Ash remains confident that they can win, sending out Pignite. Cilan remarks that Pignite is a great matchup against Scolipede for type. Ash orders Flame Charge, but Roxie catches on that Ash is attempting to boost Pignite's speed while dealing damage, and counters with Screech. The sound waves end up being disruptive enough for Pignite to break Flame Charge. Pignite fires Flamethrower, but Scolipede dodges again and poisons Pignite with Toxic. Ash encourages Pignite not to give up and calls for Fire Pledge. Pignite manages to stand up despite the poison, launching its pillars of fire that bathe Scolipede in flames, knocking it out. Roxie surprises Ash and his friends when she tosses Pignite a Pecha Berry, curing him of his poison, saying that it wouldn't be fun facing a poisoned opponent. Nicky and Billy Jo can only remark "that's our Roxie", joining Roxie in psyching up the crowd to cheer Roxie on. Cilan is impressed at how Roxie is using the crowd in her favor, making for a truly uniquely flavored gym. Iris isn't impressed and briefly runs off. Roxie sends out her third Pokémon, Garbodor, which Ash scans.
Ash orders another Flame Charge, but Roxie orders Garbodor to dodge - which it does by pushing against the ground with its arms and extending them, shocking Ash's group. Cilan is amazed that Garbodor can limitlessly extend its arms, pointing out that this will make it difficult for Ash's attacks to connect. Ash calls for Flamethrower, which Garbodor dodges in the same way, but as this happens Ash orders a Tackle. Pignite slams itself into Garbodor's extended arms, causing the Trash Heap Pokémon to come crashing down. Ash orders Fire Pledge, but Roxie orders Garbodor to block it - using its extendable arm, Garbodor blocks Pignite's fist from connecting with the floor, stopping the move, before proceeding to strike Pignite with Doubleslap. Billy Jo rouses the crowd again, and Iris reveals herself to have brought along a ceremonial drum (much to Cilan's surprise) to cheer for Ash. Ash is happy that Iris is cheering for him, and orders a Fire Pledge from Pignite. Roxie counters with Hyper Beam, blasting through Fire Pledge and knocking Pignite out. Roxie remarks that she doesn't just stick to Poison-type attacks and techniques.
Ash sends out Palpitoad as his fifth Pokémon; Cilan once again points out the type advantage Ash has. Ash orders a Mud Shot, but Garbodor once again dodges in the same way. Roxie compliments Palpitoad for the strength of its Mud Shot before calling for another Hyper Beam, which Ash counters with Hydro Pump, cancelling it out. The water spray causes Pikachu to briefly take notice of Meloetta, who has been watching the battle; she quickly hides herself with invisibility. Ash orders another Mud Shot, but Garbodor responds with Gunk Shot, launching a trash bag that meets Mud Shot head-on. The trash bag bursts to release poison-coated garbage, striking Palpitoad and poisoning it as well. Roxie follows up with Venoshock as Garbodor soaks Palpitoad in green goop, shocking its system. Ash is stunned at this latest development as Cilan explains that Venoshock deals a lot of damage if the target is poisoned. Garbodor launches another Venoshock, dealing heavy damage to Palpitoad and fainting it.
Ash finishes up with Pikachu as his final Pokémon. Roxie again compliments Pikachu's cuteness while Ash says that Pikachu is strong, and ending things with equal numbers is alright with him. Cilan and Iris are worried that Ash is down to his last Pokémon. Roxie begins by ordering Doubleslap, and Garbodor sends its arms out to lash at Pikachu. Ash orders continuous dodges with Pikachu weaving in and out of Garbodor's arms, causing Garbodor's arms to tangle up! Roxie is surprised at this new development as Pikachu uses Quick Attack, hitting Garbodor in the face. Garbodor tries to attack again, but Pikachu dodges and fires Thunderbolt to knock Garbodor over. As Garbodor gets up, Ash orders an Iron Tail, but Roxie has Garbodor swing its arms to throw Pikachu off, and orders a flurry of Gunk Shots. Pikachu is cornered by the flying exploding trash bags, and Roxie calls for Garbodor to grab Pikachu and pin it to the ceiling before releasing, letting Pikachu plummet into range of Doubleslap and unable to counter. The crowd cheers Roxie on as Ash falters, unable to think of a way out. Distressed and angry, Iris drags Cilan off for another plan that Cilan is initially very unnerved with.
After continuous Doubleslaps, Garbodor notices that its arm is somehow getting numb. Roxie orders for another Gunk Shot that hits, poisoning Pikachu. Ash is extremely worried at this point but much to his surprise, Iris and Cilan cheer him on with a pair of ceremonial drums and their faces all painted up. The sight encourages Ash and Pikachu as the latter manages to stand up. Roxie orders another Gunk Shot from Garbodor, but is shocked to see her Pokémon locked in paralysis! Cilan shouts that Static has taken effect after Garbodor's Doubleslap, severely hampering its movements. Pikachu fires a Thunderbolt which Garbodor unwillingly takes. Roxie calls for Venoshock, but before Garbodor can attack Ash orders Electro Ball, finally knocking Garbodor out. The stunned referee declares Ash the winner of the match.
Ash rushes onto the field to pick up his poisoned Pikachu, while Roxie retrieves Garbodor, handing him a Pecha Berry for Pikachu. Iris and Cilan congratulate Ash on his win, and Ash thanks them for the encouragement, though somewhat bemused by their face paint. Roxie is somewhat disappointed and surprised that she's finally lost, but nonetheless awards Ash with the Toxic Badge as her band and fans all cheer him on. Meloetta is visibly pleased at the result and flies away.
The narrator concludes the episode by stating that Ash has now qualified to enter the Unova League.
Team Rocket hijacks the Live Caster from Professor Oak at the beginning of this segment. They took over Professor Oak's role of taking charge of an eight-week movie-related promotion that gave fans a chance to win prizes.
Iris and Cilan's face paint used motifs of fire and lightning; possible references to Reshiram and Zekrom. In addition, Iris is assigned the motif of lightning - in the games, Iris is the Gym Leader faced in Pokémon White version, of which Zekrom is its mascot.
