Ash returns to Kanto with his friends, their Pokémon, Professor Kukui and Principal Oak as part of a special school project about the differences between Kanto and Alolan Pokémon. Misty and Brock are waiting for him at the airport, and Brock shows he hasn't changed as he first cares for Lillie's Snowy and then chases after a pretty flight attendant. The gang from Alola have a grand time with their Pokémon seeing and interacting with their Kanto counterparts at Professor Oak's lab. Ash's herd of Tauros naturally stampede on him, and he happily reunites with his Bulbasaur and Muk. Kiawe races a Rapidash on his Ride Charizard and then rides it. Mallow and Steenee have an unfortunate interaction with a Kanto Vileplume. Sophocles and Togedemaru meet a Kanto Raichu with shocking results. Snowy meets a Kanto Ninetales. Lana and Popplio meet a Kanto Dewgong and then swim with Misty and other Water Pokémon. As Ash, Misty, and Brock remember old times, it's great to see that some things haven't changed (Misty is still terrified of Bug Pokémon). Team Rocket have also returned to Kanto on orders, and their latest (and old-school) plot to steal everyone's Pokémon using a giant mecha reunites the original trio as battling partners including Ash's Lycanroc, Misty's Staryu, and Brock's Crobat. However, the battle is once again interrupted by Bewear (wearing a jet-pack!), and another old acquaintance, Jigglypuff, finishes things off in its usual fashion. The day ends with a magnificent outdoor feast prepared by Delia and Mr. Mime, spied upon by Mew! (Source: Wikipedia)
