Mohn

Spoiler warning: this article may contain major plot or ending details.

Mohn was Lusamine's husband and is Lillie's and Gladion's father.

During the events of the games, Mohn watches over Poké Pelago and explains its functions to the player. He does not appear in the plot of the story, but offers context and lore. In Ultra Sun and Ultra Moon, he does visit the player in person on Route 7 after they have finished Kiawe's trial, telling them to visit the archipelago if they wish to have some fun with the Pokémon who are resting in their PC boxes.

As a professor working for the Aether Foundation, he was the first to confirm the existence of Ultra Wormholes and Ultra Beasts. A few years before the events of Pokémon Sun and Moon and Pokémon Ultra Sun and Ultra Moon, he vanished while on a mission to try to connect to an Ultra Wormhole, leaving behind only a weakened Cosmog, some papers on the Ultra Beast, Nihilego, and a theory on the Ultra Wormholes. It is uncertain how he ended up on Poké Pelago, and it is never discussed during the events of the games. Scientists found in Professor Burnet's Dimensional Research lab in Heahea City mention Mohn and his research on Ultra Wormholes, implying that some of his research was publicly known.

The research that Mohn has conducted can be found in the Lab area of Aether Paradise. According to documents found in Secret Lab B, it was discovered that another dimension was found beyond the Ultra Wormholes. Pokémon-like life was found in these wormholes and were named Ultra Beasts. Research found in the same lab suggests that Cosmog is speculated to be a type of Ultra Beast from another dimension that can create Ultra Wormholes under extreme life-taking stress. This dimension that it comes from was named Ultra Space. The Aether Foundation is working to experiment on Cosmog's stress in order to manipulate Ultra Wormholes to appear.

In Ultra Sun and Ultra Moon, after defeating Gladion at the Pokémon League, a month after the events of the game, Mohn will pay a visit to Aether Paradise. Upon seeing Lusamine, he introduces himself as Mohn and compares the Paradise to Poké Pelago. They exchange thoughts on Pokémon conservation and how a Pokémon may just be left in a Trainer's PC boxes alone. Lusamine asks if it is his first time visiting Aether Paradise, to which Mohn affirms. He does not seem to recognize the facility or Lusamine. Accepting that Mohn has both completely forgotten his past and finally found happiness, Lusamine bids him farewell.

Lusamine and Mohn's wedding photo

Pre-series

As a younger man, Mohn moved to the Alola region to continue researching Ultra Wormholes. He was also a powerful Trainer, who defeated Hala and earned himself a Z-Ring.

He founded the Aether Foundation alongside his wife Lusamine, and their colleagues Faba and Wicke. One day, Mohn was sucked into an Ultra Wormhole during one of his experiments, and had been presumed dead ever since. This accident caused Lusamine a lot of grief and she decided to never talk to her young children about their father. Lusamine almost placed his research into confidentiality, though Faba ended up moving it all to his lab on Aether Paradise.

Pokémon the Series: Sun & Moon

Mohn debuted in Mission: Total Recall!, where he was partially seen in a wedding photograph with Lusamine.

Mohn made his physical debut in a flashback in Showdown on Poni Island!. Lillie encountered her brother Gladion on Poni Island while he was searching for Tapu Fini, having heard that it possessed the ability to allow the living and dead to see each other again. Lillie said she had heard that he passed away while researching Ultra Wormholes, but Gladion was unable to confirm this.

In Memories in the Mist!, Gladion and Lillie searched through Tapu Fini's mist for Mohn, but were unable to find him. Hapu informed them that this was likely because Mohn was, in fact, still alive, and they decided to tell Lusamine of this possibility.

In The Secret Princess!, the Aether Foundation began searching for Mohn after Gladion informed Lusamine of his findings. Lusamine came to realize that her children were still very interested in their father and went on to reveal his secret study inside the family's Melemele Island mansion and entrust it to their care for the time being. She and Hobbes also revealed a lot about Mohn's past as a Trainer. Lillie discovered her father's Z-Ring, and she later received permission from Hala to temporarily wield it. She also uncovered an inactive Shiny Magearna, which Mohn had planned to repair so it could be a friend for her, but he never managed to get it working before he disappeared. Lillie then found one of her father's journals tucked behind the Artificial Pokémon, which documented his notes on Magearna.

In Chasing Memories, Creating Dreams!, when Gladion located his Zoroark on Melemele Island, Zoroark created an illusion of a moment from Gladion's childhood involving Mohn. Gladion informed Mohn that the then-infant Lillie was crying, earning thanks from Mohn. Lusamine then entered the room with Lillie, and Mohn helped her to stop crying.

Mohn briefly appeared in a flashback in Final Rivals!. When Gladion sent Zoroark out during his battle with Ash in the Manalo Conference, he thought of Mohn and asked his father to give him strength.

In Dreams of the Sun and Moon!, Mohn appeared, again as a part of Zoroark's illusion, which recreated the day Lillie first learned how to walk as an infant.

Mohn appeared in a flashback in Thank You, Alola! The Journey Continues!, where he was seen in a photo.

Mohn's family

In The Homecoming Crown!, Mohn was revealed to be living in the Crown Tundra, where his family found him. However, it turned out that he had amnesia and failed to remember them. They soon found out that he was living with a Shiny Nihilego, which he thought was his daughter, also called Lillie. The family eventually figured out that Mohn had wound up in Nihilego's world, where it had rescued him from and brought to the Crown Tundra in the Galar region through another Wormhole. It had then used its powers to make him see it as his daughter and lived with him for years, removing all the mirrors in the house and dirtying all the windows to prevent Mohn from seeing his reflection and regaining his memories, fearing that Mohn would leave it if he did. When Gladion showed Mohn his image in a mirror, he finally remembered everything and was truly reunited with his family. Before the Nihilego could fly away, it was invited into the family and caught with a Beast Ball.

In Helping the Hometown Hero!, Mohn's family, Ash, Goh, and Chloe arrived in Alola, attending a party to celebrate their return. During the party, Mohn reunited with Hobbes, Faba, Wicke, and Hala. The next day, Mohn watched Gladion participate in a Battle Royal match between Ash, Kiawe, and Professor Kukui.

Main article: Ultra Beasts (anime) → Lillie

This Shiny Nihilego encountered Mohn when the Ultra Wormhole he passed through brought him to its world. Hearing him calling for Lillie while unconscious, Nihilego read his memory and learned of his lost family in Alola. It tried to bring him back by dragging him through another Ultra Wormhole, only for the pair to end up in the Crown Tundra instead. Nihilego brought Mohn to an abandoned house nearby, where it used its powers to make him see it as Lillie. They lived together in peace, with Nihilego playing the role of Lillie and concealing anything that could cause Mohn's memory to return, until the real Lillie's family found them. They managed to help Mohn overcome his amnesia, and together, the family welcomed Nihilego, as it had saved Mohn, made it possible for them to reunite with him, and had, in a way, become a second Lillie. They caught it in a Beast Ball and Gladion took it under his care.
