Ash Tai Power Hour

Ash Tai Power Hour is a crossover between the Pokémon and Digimon franchises. This movie has spun two sequels.

Plot
Tai and his friends hasn't started a project for the Digital World Convention. Tai uses the Digi-Telport, given by Sora for the convention. He then uses it to go to the greatest place in the universe. Tai (Now appears in a Pokémon animation style) arrives on the streets of Lumiose City. Ash is currently eating lunch with Pikachu when Tai drops in and starts to mess with his stuff. Ash accidentally uses Tai's Digi-Teleport, causing him to disappear to the Digital World. Looking at Team Rocket's device, Tai mistakens it for a Digi-Scanner, he put the device on Pikachu, causing it to turn on and signals it to Team Rocket.

Just then, Clemont and Bonnie drop by and mistaken Tai for Ash, due to Celemont thinking that Ash has became a member of the DigiDestined. After playing with some of the Pokémon and stealing a jet pack, Tai rockets himself across the city, and Tai bumps into Serena who falls in love with Tai. Meanwhile, Team Rocket find themselves in Lumoise City and kidnaps Pikachu. They then go through the city, stealing many of the Tamed Pokémon and their trainers, save for Serena, Clemont, and Ash (except Pikachu, but including all of the Pokémon back at Prof. Oak's Lab).

In the Digital World, Ash (Now appears in a Digimon Adventure animation style) finds himself in the Digital World 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, Guilmon, Renamon, Riki, and everyone in the Digital World stupidly believes that Ash is Tai in a costume. Then Ash gets fed up with the place, and decides to get the Digi-Telport to send him back home and send Tai back here. 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 and then Sora finally understands and hopes that someday, Tai will return to the Digital World and reunite with her. The next day, The next day, Yukio sees Ash with the Digi-Teleport, and he plans to teleport himself into the Digital Castle. When Ash got the remote attached to the Digi-Teleport and about to go home, Yukio snatches it from his hand and presses the button, causing him, Ash, Sora, Matt, Izzy, Mimi, T.K., Joe, Kari, and their Digimon partners to teleport to the Digital Castle.
