The time has come for Ash, now armed with his new Grassium Z-crystal, to face Olivia in the Akala Island Grand Trial Challenge, and Rockruff wants to battle Lycanroc even before the Trial gets underway. This will be a Double Battle; Olivia brings out a Probopass to partner her Lycanroc, and Ash chooses Rowlet to partner Rockruff. The battle is intense, with both Olivia and Ash using Z-moves. With Ash's new Grassium Z-move Bloom Doom, Rowlet defeats Probopass, but then the unthinkable happens: Rockruff wants to battle Lycanroc so fiercely that it attacks Rowlet without thinking when Ash orders Rowlet to help Rockruff. Rockruff is horrified by what it's done, but Ash forgives and encourages his Pokémon, and Rockruff goes on to defeat Lycanroc. Olivia presents Ash with a Rockium Z-crystal and tells him that Rockruff may evolve soon. Tapu-Lele appears to honor Ash and Rockruff.

Rockruff, injured after falling into a river, is found by both Olivia's and Gladion's Lycanroc and brought to the Ruins of Life. Ash arrives with Olivia and Professor Kukui in time to stop the Island Guardian from battling the two Lycanroc.

Ash and his friends have returned to Melemele Island, but Team Rocket is there to welcome them by trying to steal Pikachu once again! When Ash's new Z-move Continental Crush fails, Kiawe's Z-move sends Team Rocket blasting off. However, Bewear fails to appear and Team Rocket crashes separately, with Jessie and Mimikyu landing in a shopping mall. Mimikyu's disguise has been badly damaged, so Jessie first devises a temporary disguise from a paper bag and then tries to find something new. While James, Meowth, and Wobbuffet search for their missing partner, Ash and Lycanroc try to master Continental Crush. Jessie eventually repairs Mimikyu's Pikachu disguise, but it is stolen by a flock of Murkrow who were actually after Jessie's malasada. James, Meowth, and Wobbuffet catch up to Jessie just as she retrieves both disguise and malasada. The angry Murkrow return in force, but Mimikyu resumes its Pikachu disguise and drives them off. Full of confidence in their closer bond, Jessie and Mimikyu challenge Ash again. However, Ash and Lycanroc have mastered Continental Crush and send Team Rocket blasting off again, but this time Bewear rescues them.

A television crew has come to Mallow's family restaurant, outside of which Team Rocket has set up an unsuccessful competing food truck. However, when Mallow's father overworks her and appears unappreciative of her efforts, she loses her temper and runs off with Steenee in pursuit. Naturally, Team Rocket sees an opportunity and chases after them. When Mallow knocks herself out in a fall, she is found and cared for by a Oranguru. While Mallow's remorseful father and the gang search for Mallow, Team Rocket captures Steenee. Oranguru's psychic powers free Steenee, and the two combined prove more than a match for Team Rocket. Bewear appears, but it and Oranguru refuse to fight each other, and Team Rocket is once again carried off. When Mallow's father and the gang arrive, Mallow's father recognizes Oranguru as his cooking teacher, and he and Mallow reconcile.

With everyone safe, Kanoa finds the Mystic Water and gives it to Ida.

Sophocles enters a special race with a miniature car powered by his Charjabug against other Charjabug-cars. Ash and Kiawe are keen to help, with Ash acting as track partner and Kiawe as mechanic. The problem is that Charjabug can't seem to generate enough power to make its car run very fast, but it gets stronger and faster with all three Trainers' help. On the day of the race, they find that they have a rival team with a flashy Charjabug-car and a very arrogant attitude. Team Rocket has also entered the race, with James as track partner, Jessie as track spotter, Wobbuffet/Mareanie supposedly as mechanic, and a fake Charjabug-car run by Meowth inside it. The race has three stages: 1) a rocky terrain, 2) a desert terrain, and 3) an urban area, each with obstacles powered by a Pokémon. However, with Sophocles as track spotter, some unorthodox moves and teamwork and Team Rocket's cheating exposed, Team Sophocles puts up a good fight. Ash is knocked unconscious in the urban area, but Sophocles takes over as track partner, and he and Charjabug bring in the victory.

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!

The previous day was all fun, but the next day brings more interesting things for Ash and the Alolan visitors as they and their Pokémon travel to Misty's Gym in Cerulean City. After explaining about Gym Battles and Pokémon Leagues, Professor Kukui announces that the class will be engaging in Gym Battles against Brock and Misty. After two practice battles (Mallow, Steenee, Lana and Popplio vs. Misty and Psyduck and Lillie, Snowy, Sophocles and Togedemaru vs. Brock and Geodude), real Gym Battles will now be fought: Kiawe vs. Brock and Ash vs. Misty, but each battle is taken to a new level with Brock and Misty both revealing they have Key Stones and using Mega-Evolution. Kiawe's Z-Move Inferno Overdrive proves useless against Brock's Mega-Evolved Steelix and Turtonator is defeated, but Ash and Pikachu's unorthodox strategy and his Z-move Gigavolt Havoc defeat Misty's Mega-Evolved Gyarados.
