(Japanese: オレの夢、ポケモンマスター！！My Dream, Pokémon Master!!) is the 142nd and final episode of the Best Wishes series, and the 799th episode of the Pokémon anime. It first aired in Japan on September 26, 2013.
After arriving in the Kanto region, Ash goes back to his hometown Pallet Town. He immediately decides to visit his Pokémon at Professor Oak's Laboratory, where he reunites with them along the companions he had during his journey through the Unova region. However, Team Rocket bursts in once again and tries to steal all the pokemon, but is sent blasting off when Ash's Unova team (including Ash's Charizard and Ash's Pikachu) each use an attack to form a group attack! Soon, it is time to leave for Kalos. Ash bids good-bye to his pokemon, and sets off for a new adventure!
This episode is, to date, the largest gathering of all of Ash's Pokémon at one time. It should be noted that with the exception of Pikachu, Bulbasaur, Tauros and the Pokémon he traveled with in Unova and the Decolore Islands, Ash's other Pokémon only appear in a photograph shown during a post-credits scene.
All of Ash's Unova Pokémon are seen together for the first time.
As of this episode, Palpitoad is the Pokémon with the most episodes absent while still being in rotation of all main characters' Pokémon.
This episode marks the first time since EP274 that no other protagonists other than Ash have appeared outside of fantasies and flashbacks.
As of this episode, Ash's Charizard permanently returns from training in the Charicific Valley, staying behind at Professor Oak's Laboratory with the rest of Ash's Pokémon, rather than going back to the care of Liza. It marks the first time Charizard has stayed at the lab under the care of Professor Oak.
