At Ten Carat Hill, Ash and Gladion discussed Cosmog before battling with Lycanroc and Silvally. The battle ended when Lycanroc lost control over its dirty mane, and Gladion left after agreeing to meet Ash again at the Alola League.

• Gladion said he would defeat Cosmog if it revealed itself to be a dangerous Ultra Beast, while Ash insisted Cosmog was different.

• Ash's Lycanroc battled Gladion's Silvally, but it went berserk after being knocked into a pond and getting its mane dirty.

• Gladion said he wanted to battle Ash's Charizard and Greninja, and Ash invited him to compete in the Alola League.

Faba took Type: Null from Gladion and tried to keep Lillie from recovering her memories of the past. As Lillie and Ash explored the underground laboratory, Gladion revealed Faba’s actions to Lusamine, who learned that Faba had opened an Ultra Wormhole without permission.

Ash and the others went sledding on Mount Lanakila, where Alolan Ninetales and Snowy enjoyed the snow and the group encountered Ice-type Pokémon. During a rest stop, Hoopa astonished Professor Kukui by fetching food from Li Wei’s home through a golden ring.

• Professor Kukui announced that he and Li Wei would take the students sledding on Mount Lanakila, and Lillie told Snowy that the mountain was its home.
• Li Wei, Professor Kukui, Hala, Kiawe, Ash, and the others arrived at Mount Lanakila, where Alolan Ninetales and Snowy played in the snow while the group started a snowball fight and built a snowman.
• Professor Kukui explained that Pokémon could evolve on Mount Lanakila, and Hala planned to evolve his Crabrawler into Crabominable.
• The group encountered Ice-type Pokémon as they walked toward the sledding area, then stopped for a thirty-minute rest because the snowy path had tired some of the students.
• Li Wei asked Hoopa to bring over food, and Hoopa used a golden ring to fetch the food from Li Wei’s dining table at home, leaving Professor Kukui amazed.

Li Wei, Ash, and their friends visited Mount Lanakila to watch Hala’s Crabrawler evolve and enjoy the snow, where they met sled racer Sarah. After Crabrawler evolved into Crabominable, the group headed to the competition grounds and reunited with Sarah.

• Li Wei shared sandwiches with the group, and Lillie noticed Snowy was missing, so Ash and the others went to search for her.
• Ash and Sophocles found Snowy with Sarah and her Alolan Ninetales, and Sarah invited them to enter the next day’s Pokémon sled jumping competition.
• Hala’s Crabrawler defeated Sneasel with Power-Up Punch and evolved into Crabominable, whose fistprint matched tracks the group had found in the snow.
• Hala said he planned to enter Crabominable in the competition, while Li Wei’s Alolan Ninetales showed little interest in sled jumping.
• At the competition grounds, Sarah greeted Li Wei and told him she was a devoted fan.

Li Wei, Ash, Lillie, Kiawe, and Hala visited Mount Lanakila to enter the Poké Sled Jumping Competition and practiced with Sarah. Lillie overcame her fear enough to jump with Snowy, who began learning Aurora Veil before the competition started the next day.

• Li Wei and the others met Sarah at the ski jump venue, where she invited them to enter and practice for the competition.
• Ash, Kiawe, Lillie, Li Wei, and Hoopa decided to compete, and Sarah explained the event and led them to a practice ground.

• Sarah and her Alolan Ninetales began teaching Snowy Aurora Veil, and the competition was set to begin the next day.

The competitors took part in the Mount Lanakila Pokémon Sled Jump competition, where Li Wei and Hoopa’s Trick Room performance won them the championship. Lillie and Snowy placed third after successfully using Aurora Veil, while Kiawe and Ash crashed and received no scores.

• Hala and Crabominable opened the competition with a powerful jump and earned high scores.
• Kiawe and Turtonator failed to get airborne because Turtonator’s weight pulled the sled down, leaving them with no score.

• Li Wei and Hoopa used Trick Room to create a colorful aerial display and landed steadily, winning the competition ahead of Hala and Crabominable.

Li Wei explained to his class how environmental and cultural pressures shaped regional Pokémon forms, using Galarian Farfetch'd as an example. He suggested their enormous leeks accounted for much of their extra weight.

• Ash remained fourth in the Alola Master League rankings, putting his place in the Top 32 at risk, while Li Wei led the standings.

• Li Wei described Galarian Farfetch'd's darker feathers and stronger legs, then proposed that their huge leeks accounted for much of their extra weight.

• Li Wei told Lillie and the class that Galarian Farfetch'd's fighting lifestyle strengthened its body and might allow it to evolve into Sirfetch'd after reaching a peak of skill and spirit.

• Professor Burnet reported that research with Professor Kukui, Professor Rowan, and Professor Oak had confirmed Ultra Beasts were Pokémon with virtually no difference from other Pokémon.
• Lusamine played surveillance footage of Buzzwole defeating Incineroar and Pangoro, then sent its data to Pokédex Rotom, which identified it as Bug and Fighting type.

Ash and the others launched their first Ultra Guardians mission to catch Buzzwole and return it through an Ultra Wormhole. As they approached, Buzzwole had already begun a contest of strength with Bewear.

• Li Wei suggested Buzzwole might be naturally combative, and Lusamine assigned the Ultra Guardians to catch it and return it to its original world.
• The team received Beast Balls and a first aid kit, then flew out from the Pokémon School while Li Wei tracked Buzzwole and sent Latias and Latios to help.
• Li Wei spotted Bewear behind Buzzwole and reflected that he would only consider taking Bewear and its child along if they wanted to leave Alola.
• Bewear and Buzzwole faced off in a stalemate of strength as Meowth watched nearby and wondered what the muscle-bound Pokémon was.

Buzzwole fought Bewear, drained Snorlax for food, and battled Ash and Pikachu before getting distracted by a bodybuilding pose contest. Li Wei chose to leave the harmless Poipole alone as it watched Ash’s group.

• Buzzwole wrestled Bewear at the lake until Bewear retreated to keep Jessie, James, and the others safe.

• Poipole appeared near the lightning, and Li Wei told Latias and Latios to leave it alone because it would likely approach Ash by itself.
• Buzzwole admired Kiawe’s muscles and started posing with him, then Ash and Pikachu joined their bodybuilding contest.

After Cosmoem’s evolution dream, Ash and his friends gathered at the Altar of the Sunne to say goodbye as it became Solgaleo and returned to Ultra Space. Li Wei reassured Ash that Solgaleo would return, leaving Ash hopeful despite their separation.

• Sophocles caught Buzzwole, and Li Wei sent it back to Ultra Space through the portable Ultra Wormhole device.
• Ash dreamed that Cosmoem evolved into Solgaleo and vanished into an Ultra Wormhole, then told Li Wei, Professor Kukui, and his friends.
• Li Wei told Ash that Solgaleo needed to return to Ultra Space, and Ash agreed to say goodbye after school.
• At the Altar of the Sunne, Cosmoem evolved into Solgaleo, which accepted Konpeitō from Ash and affectionately licked him and Pikachu.

• Hoopa steered the wedding bouquet into Cynthia's hands, and Li Wei and Cynthia told Professor Kukui and Professor Burnet they planned to marry by the following year.
• Lusamine asked Ash about Gladion, and Ash reassured her that he expected to meet Gladion at the Alola League Conference; Lusamine then invited Lillie to dinner.
• Ash watched a Battle Royal rerun and became interested in the competition after seeing Incineroar fight, while his classmates discussed the Masked Royal's winning streak.
• Sophocles told Ash and the others about an upcoming Masked Royal exhibition match, and the group agreed to attend; Li Wei entered class knowing Professor Kukui was the Masked Royal.

Ash and his friends attended the Masked Royal’s fan event at the Battle Royal Dome, where Ash’s Litten rushed onto the stage and challenged Professor Kukui’s Incineroar. The three-on-one match left Litten battered but still defiant, and the Masked Royal told Incineroar to answer its resolve as they faced off for a final clash.

• The Masked Royal appeared at the Battle Royal Dome with Incineroar while Jessie, James, and Meowth hosted the event.
• Litten recognized Professor Kukui beneath his mask, rushed onto the Battle Stage, and prompted him to invite Ash, Kiawe, and Sophocles to battle.
• Ash sent out Litten, Kiawe chose Marowak, and Sophocles chose Charjabug for a three-on-one Battle Royal against Incineroar.
• Incineroar’s Darkest Lariat quickly knocked out Charjabug and Marowak, while Litten narrowly avoided the attack but was badly hurt.
• Litten got back up and defiantly challenged Incineroar, prompting the Masked Royal to tell Incineroar to answer its resolve.
• Ash ordered Litten to use Fire Fang as the Masked Royal called for Incineroar’s full-power Inferno Overdrive.

After losing to the Masked Royal’s Incineroar, Ash and his friends trained with Litten until it evolved into Torracat during a rematch. Torracat mastered Flame Charge and broke through Incineroar’s defenses, but their battle continued.

• Litten lost to the Masked Royal’s Incineroar, and Ash carried it from the battlefield.
• Ash and his friends trained Litten to learn Flame Charge, while Li Wei helped by feeding it spicy, Fire-energy-rich Pokéblocks.
• Two days later, the Masked Royal challenged Ash to a rematch, and Incineroar quickly overpowered Litten again.
• As Incineroar held it, Litten’s determination triggered its evolution into Torracat.
• Torracat used Flame Charge to break through Darkest Lariat and burn Incineroar’s arm, then prepared to attack again.
