The Ash Tai Power Hour
Tai and his friends hasn't started a project for the Digital World Convention. Tai uses the Digi-Telport, given by Sora. Then, he used it to go to the greatest place in the universe. Tai, who now appears in the Pokémon XY anime style, arrive on the streets of Lumiose City. Ash accidently uses Tai's Digi-Teleport, causing him to disappear to the Digital World.

Just then, Clemont and Bonnie drop by and mistaken Tai for Ash. After looking with some of the Pokémon, Tai bumps into Serena who falls in love with Tai. In the Digital World, Ash, who now appears in the Digimon Adventure anime style, finds himself in the Digital Forest and meets Sora, Matt, Izzy, Mimi, T.K., Joe, and Kari. When Ash sees their Digimon partners, he thinks they're not real. T.K tries to prove to Ash that Digimon exist, but Ash refuses to believe.

And worse, Greymon, Riki, Renamon, and Impmon all mistake Ash for Tai. Ash then mistakes the Digimon for wild Pokémon. As Sora and Kari head towards the Digital Forest, Sora was so sad that Tai is gone, revealing that she's in love with him. Kari convinces that Tai will come back someday. Sora finally understands and hopes that someday Tai will return to the Digital World. The next day, Ash inadvertently uses the Digi-Teleport in front of Yuiko, who comes up with a plan to teleport himself into the Digital Castle. Ash combines it with Tai's remote in order to teleport anywhere. But after successfully tracking Ash to the Digital Forest, Yuiko manages to steal Ash's device that would return him to Retroville (because Ash wants to go back to Kalos and Tai wants to go back to the Digital World), and wants to teleport himself, Sora, Matt, Izzy, Mimi, T.K., Joe, Kari, and their Digimon to the Digital Castle instead. Back in Kalos, Serena and Tai enjoy hanging out with each other, until Team Flare corrupts all the Trainers' Pokémon in Kalos and kidnaps them (except Serena, Clemont, and Bonnie, who managed to avoid that along with their Pokémon as well). Clemont and Bonnie try to get them back to normal, but the corrupted Pokémon was too strong for them. They came to Tai and Serena for their help, but Team Flare kidnaps Tai (and also mistakes him for Ash) as will. Tai, with Serena's help, manages to rescue all the trainers and free all the corrupted Trainers' Pokémon. Team Flare is then sorry for kidnapping him and the other Pokémon trainers and corrupting all the Pokémon, then finally left for now. When the trouble was all over, Tai, Serena, Clemont, and Bonnie are happy that the Pokémon and their trainers are okay.

In the Digital Castle, Ash comes in contact with Tai. However, Ash refuses to listen to Tai's plan to get Yuiko out of the castle and refuses to help him at all, though at times he always tries his hardest, despite the fact that he is stupid. As Yuiko corrupts all of the Digimon (including the DigiDestined), he becomes the new owner of the Digital Castle. After talking with Tai, Ash comes up with a plan to defeat Yuiko, and save the Digital Castle. So he tells T.K. and Kari to distract Yuiko so he could make a Digi-Vice to transform into Lizardonmon (who looks like Charizard, but speaks the language the Digimon would usually say instead of speaking Pokémon language) and defeat Yuiko. Using some of Lizardonmon's attacks, Ash finally defeats Yuiko, making him powerless, and transforming the Digimon back to normal. Yuiko is attacked by Greymon, causing Yuiko to lose all memory of the Digital World.

Tai tells T.K. and Kari to reopen the portals for him and Ash. The two of them shake hands in the area between both of their worlds. It was finally time for the Digital World Convention, who is being judged by Renamon and Riki. Sora, Matt, Izzy, Mimi, T.K., Joe, and Kari note what a good day they've had, before Tai reminds them that he still hasn't finished his science project yet, until Charizard, who now appears in the Digimon Adventure anime style, finally appears out of the wormhole, amazing everybody.
