In Team Rocket Trouble, Ash is attending Pokémon School in Alola, where Professor Kukui gives him a new Pokédex called a Rotom Dex. With its help, Ash is confident he can catch more Pokémon. But trouble brews when Team Rocket—his perennial adversaries—shows up in Alola seeking mischief. They complicate Ash’s efforts, leading to a battle of wits, daring escapes, and Pokémon showdowns.
