Ultra Adventures
One night, Ash has a dream where he promises the Legendary Pokémon Solgaleo and Lunala. However, Ash could't recall it that next morning. While heading to school, Ash and Pikachu saw Tapu Koko coming back as they follow it then saw an unknown Pokémon which helped him remember the promise he made to the Cosmic duo. Ash brought it to school to show everyone then Lillie nicknamed it Nebby with everyone liking the name and they all agreed to call it Nebby. Ash help find something Nebby would like to eat but it didn't like anything they gave it all until Sophocles provided a bag of star candies with it liked a lot. Ash and Lillie were heading to Professor Kukui house where they see a helicopter on the beach as Professor Kukui explained that they have visitors who want to see them. Ash meets Lusamine, Lillie and Gladion mother, the president of the Aether Foundation along Professor Burnet, Wicke and Faba as they all came to meet Nebby. Ash shows Nebby to Lusamine where she concludes that it's an Ultra Beast then Professor Burnet explains about the Ultra Beast and the battle they had with the Tapu Guardians. Ash tells them the dream he had that night about the promise he made to the Cosmic duo, after seeing an image of the Altar of the Sunne. Although Lusamine and Wicke offer to take care of Nebby, Ash declined their offer due to his promise to take care of Nebby. After Lillie and Professor Kukui assured Lusamine that he is a very trusting trainer as they tell her all the accomplishments he has done in Alola, Ash was allowed to take care of Nebby and Lusamine offer to help him whenever he needed it.

Ash has some awesome adventures with Nebby especially when it learned teleport as it teleported him and his friends to various places, minus Lillie. Ash got to go to Aether Paradise with his friends which is where the Aether Foundation is located as he got to Lusamine, Wicke, Faba and Professor Burnet again.

By accident when Nebby teleported him, Ash meets up with Gladion again, after he thought about him, with Pikachu and Lycanroc where he meets his Type: Null, nicknamed Silvally. Ash tells Gladion that Lillie is doing well also during the conversation Gladion explained why Lillie's afraid of touching Pokémon, due to an Ultra Beast attacking Lillie back when she was little, and his Silvally saved them. Ash wonders why Lillie never explained this but Gladion believes the trauma she suffered caused her to repress the memory of those events. Ash was asked a lot of question by Gladion as he is curious as to why the Cosmic duo chose him to take care of Nebby, about his Dusk Lycanroc, what powers does he possess and what kind of influences does he have on Pokémon. However, Ash doesn't have all the answer to Gladion questions but decided to have a battle, as Team Rocket interrupted before, as he believes this will help him answers his questions. Understanding the idea and accepting his challenge, Ash with Lycanroc put up a good fight against Silvally but lost then Gladion understood more about him also he has him promise not to tell anyone he saw him also about Silvally, especially Lillie, which he understood and promised he won't say anything.

Ash is hanging with Professor Kukui and Professor Burnet, who came to give Nebby a check up, along with his Pokémon. Then Kiawe, Lana, Lillie, Mallow and Sophocles came over as they are having a sleep over at Professor Kukui house. Ash invited Professor Burnet to join them and she gladly accepts as everyone gets settled in. Ash suggested having a contest to see who gets to sleep in the loft, as Sophocles and the girls want to sleep up there, with finding Nebby being the contest. After the contest, with the girls being the winner due to Nebby pooping out of Lillie's hat and into her arm freezing her in fear, they play a game call Z-Posses one, two, three but Kiawe got carry away and used Inferno Overdrive messing up the place. Ash, Mallow, Lillie and Professor Burnet make dinner while Professor Kukui has the rest help him clean up the place. Just when everyone was about to eat, Professor Burent's Munchlax swooped in and ate everything promoting the two Professor to go out to get something to eat for everyone while the others wait. While waiting, Ash and everyone decided to some training for Pokémon battle to help them forget how hungry they were. After eating, they all talked about how amazing Professor Burnet is along with talking the about the homemade food at Kiawe and Sophocles place, right before going to sleep for the night. The next day, everyone is walking along then Ash and everyone became stunned when Lillie could't touch Pokémon again even Snowy, as Nebby teleported her to Gladion's location where she saw his Type: Null which triggered a memory from her past.

At night, Ash was at the beach getting scolded by Gladion for having Nebby bring Lillie to where he was then apologizes for it's action. The next day at school, Ash and everyone cheer Lillie up then witness her try to touch Snowy but got scared. However, Ash and everyone praised Lillie for her courage. After school was done, Ash, Nebby, Pikachu and Rotom decided to take a walk with Lillie and Snowy. While walking, Ash was asked by Lillie if he saw Gladion which he admits that he did see him as he explains that he didn't want her to see Silvally then told how upset he was which got his friend to laugh due to knowing her brother. Ash hears Lillie tell him that when she saw Silvally it brought back a memory from her past. Not wanting to see his friend down, Ash cheers Lillie up by having Rotom show a video of Pikachu doing an imitation which worked. However, Ash also unknowingly encourage Lillie to not give up on getting over her fear of touching Pokémon as she decided to remember her past then they were all teleported by Nebby, who decided to help her. Being teleported from one place to another, Ash got to see all the places Lillie and her family did together before her mother, Lusamine, got busy with her work. Ash with everyone were then teleported to Lillie and Gladion childhood room located at the Aether Foundation. After being teleported to Lusamine room, Ash realized that Nebby wants to grant Lillie's wish as she wanted to remember everything then they were brought to the Aether Foundation basement which is strictly forbidden other then Aether Foundation employees. While going through the basement further, Ash, Pikachu, Nebby, Rotom and Snowy were pushed into a wall by Faba's Pokémon as Lillie is grabbed by Faba, who didn't want her to remember her past. Ash, Nebby, Pikachu and Snowy tried to save Lillie, minus Rotom as it went go get some help by pulling the alarm, but Faba's Hypno hold them down with Psychic. Ash with everyone were rescued by Gladion and his Silvally then became glad when Lillie, who remember everything from her past, touch Sivially thus putting an end to her fear of touching Pokémon for good. Ash told Lillie how happy he was for her then was thanked for his help.

After helping Lillie get over her fear of touching Pokémon, Ash, Gladion and Lillie went back to Aether Paradise when Nebby got kidnapped by Faba, who wanted it to open an Ultra Wormhole. Meeting up with Lusamine, Ash and everyone were able to rescue Nebby but it evolved which caused the Ultra Wormhole to open. Ash and everyone see Nihilego come out of the Ultra Wormhole then became stunned when the Ultra Beast took Lusamine away, who sacrifice herself to protect Lillie and Gladion. While heading back to Melemele Island, Ash offer to help Lillie and Gladion find Lusamine. However, Ash was told no by Gladion as he tells that this situation is a family matter. After arriving back to Melemele island, Ash heads back to Professor Kukui house for the night. The next day, Ash was still worried about Nebby as it hasn't moved since it evolved then Kiawe, Lana, Mallow and Sophocles came over to check on him. Ash tells his friends about what happed at Aether Paradise as they became shock that Lusamine was taken away through an Ultra Wormhole then they all hear more shocking news as Hobbes comes in with Professor Kukui to tell them that Lillie and Gladion are gone. Knowing that their trying to find a way to rescue Lusamine, Ash and everyone heads over to Hala house for some idea on where their at. Hearing Hala explain about the Altar of the Sunne and about Solgaleo, Ash remembers being their in a dream where he promises the Cosmic duo that he would take care of Nebby. Ash and everyone head to Poni Island, where the Altar of the Sunne lies, to catch up with Lillie and Gladion as they want to help rescue Lusmaine. After catching up to Lillie and Gladion, Ash tells them their reason of being here despite Gladion telling him again that's its a family matter but Ash and Lillie were able to change his opinions as he lets them come along in their quest to rescue Lusamine. While looking for Solgaleo, as it can open Ultra Wormholes, at the Altar of the Sunne, Ash and everyone come across the Tapu Guardians instead, surprising them.

Ash became amazed and shocked when the Tapu Guardians showed him and his friends that they were the ones who brought Nebby to Melemele island for him to find and take care of. Later, Ash became excited when Nebby evolved into Solgaleo then was given a Solganium-Z, as they needed to use a Z-Move to make an Ultra Wormhole. However, the Z-Crystarl didn't fit Ash's Z-RIng so the Tapu Guardian encases it for him then gave it back to him. Ash, Gladion, Kiawe, Lana, Lillie, Mallow and Sophocles all get on Solgaelo's back then Ash performs Searing Sunraze Smash. After performing the Z-Move, Ash and his friends enter the Ultra Wormhole, leaving both Professor Kukui and Professor Burnet, who also arrived to Poni island to help them rescue Lusmaine, behind.

Making it to the dimension where Nihilego lives, Ash and everyone find Lusmaine fused with Nihilego but they were blocked off by Lusmaine's Pokémon, who were stopping them from getting close to her as everyone, but Ash, Pikachu and Solgaelo kept going while the others battle the Pokémon. Ash with Pikachu and Solgaelo were able to get to Lusmaine as they tried to save her. Just when Ash was having a hard getting through to Lusmaine, Lillie and Gladion come to Ash's aid. Ash became shock when Gladion tells him that they need to stop Nihilego and free Lusmaine because her Pokémon will keep getting back up without end. While Solgaelo goes to help the others, Ash and Glaidon hear Lillie give a speech to help get through to Lusmaine which worked but Nihilego refused to let her go. Ash's Electrium-Z temporary transforms into Pikashunium-Z then he and Pikachu performed the Z-Move 10,000,000 Volt Thunderbolt which stop Nihielgo and freed Lusmaine and her Pokémon. Ash, Gladion and Lillie reunites with their friends as he tells them that they were able to save Lusmaine then returned to the Altar of the Sunne where they reunited with Professor Kukui and Professor Burnet. Ash wonders where Solgaelo, Nebby, is, as it returned to the wild, as it left without him giving a thank you for its help then greets Lillie, who took some time off from school to be with her mother, as she thanks him and everyone for their help in rescuing Lusamine. Later at Professor Kukui house, Ash became stunned but happy that Professor Kukui and Professor Burnet are getting married. The next day, Ash tells Kiawe, Lana, Lillie, Mallow and Sophocles about the news, much to the girls joy. Although the girls were hoping for a weeding, Ash tells them and the rest of the boys that the Professors aren't gonna do a weeding ceremony, disappointing the girls.
