Mohn/Anime

As a younger man, Mohn moved to the Alola region to pursue his research in Ultra Wormholes. He was also a powerful, having been able to defeat Hala and his and earn himself a Z-Ring. He founded the Aether Foundation alongside his wife, and their colleagues 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.

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

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, 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, 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.

Mohn reappeared as an illusion in Chasing Memories, Creating Dreams!, when Gladion located his Zoroark on Melemele Island. Zoroark created an illusion of a scene from Gladion's childhood in which 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 SM138. 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.
