Reunion Battles In Nimbasa! (Japanese: 全員集合！ドンバトル！！Everyone Gathers! Don Battle!) is the 39th episode of the Best Wishes series, and the 696th episode of the Pokémon anime. It first aired in Japan on July 7, 2011, and in the United States on October 29, 2011.
Our heroes think they’ve finally arrived in Nimbasa City, but their new friend Luke informs them that they’re actually in Nimbasa Town, home of the Pokémon Club Battle Tournament. Named after Don George’s Pokémon Battle Club, which sponsors the event, the tournament promises to be filled with excitement. One by one, many of our heroes’ friends and rivals show up to register: Bianca, Georgia, Burgundy, Stephan, and Trip are all in town for the competition!
Soon the matchups are announced and the action gets under way. Iris’s rival, “Dragon Buster” Georgia, is up first, and her Beartic quickly takes down her opponent’s Joltik. Later, Ash faces off against Burgundy, Cilan’s old rival and fellow Pokémon Connoisseur! Confident as ever, Burgundy chides Ash for not completely replacing his Pokémon team as she recommended during their last meeting, but our hero and his Palpitoad manage to defeat Burgundy and her Stoutland!
Next up, Cilan is set to battle Trip. Meanwhile, the Team Rocket trio have quietly arrived in Nimbasa City, confidently preparing for their next assignment...
Team Rocket arrives in Nimbasa City, ready to begin planning their latest scheme, one which is far more ambitious than all their previous ones. Meanwhile, Ash and his friends arrive at what they think is Nimbasa City, but Luke informs them that they are actually in Nimbasa Town, the site of a Pokémon battle tournament. As Ash prepares to head over to the tournament, Bianca arrives and explains that she is competing in the tournament as well.
As the group approaches the stadium, Luke begins filming his documentary of the tournament, but Bianca interrupts him and takes an immediate liking to his Zorua, asking to trade her Pignite for it, to which Luke refuses. The group then receives registration forms from Don George, and, while filling them out, they discover that Burgundy is also entering. After Burgundy reiterates her hatred of Cilan, Stephan arrives to join the party as well, with his newly evolved Zebstrika. Georgia arrives as well, wasting no time in trading insults with Iris, whereupon Ash notices Trip's presence at the front of the stadium.
The tournament soon begins, with Don George introducing the grand prize: a seven-feather wing set to improve a Pokémon's Effort values. When the first round matchups are announced, Ash finds himself facing Burguny, Cilan's opponent is Trip, and Iris is matched against a man called Jimmy Ray.
Georgia wins her battle against her opponent relatively quickly, and the tournament proceeds through the next two battles until it is time for Ash to face off against Burgundy. After Burgundy calls out Stoutland, Ash brings out his Palpitoad - which is Palpitoad's first Pokémon battle. Palpitoad opens with Mud Shot, to which Stoutland counters with Tackle. After Stoutland then tries an ineffectiveThunder Fang on Palpitoad, it then returns with an Ice Fang instead. However, before Palpitoad is completely frozen, Ash commands it to use Supersonic, which causes Stoutland to let go and also shatters the ice. After a fierce barrage of attacks from both sides, Palpitoad emerges victorious, allowing Ash to proceed to the second round.
After Zorua pulls more of her pranks by mimicking Georgia, Cilan and Trip prepare for their battle, with Cilan promising to have his performance be even better than Ash's.
