Description
Dan is a character who serves as both a guest and later an employee at the Pokémon Resort. He is the uncle of Tyler, one of the resort's regular staff members.

In his younger years, Dan worked as a fisherman and was known for having a tough, powerful physique. He raised Tyler from childhood, often taking him on boat rides, though Tyler recalls that Dan could be "super scary" and would scold him angrily when he caused trouble. By the time he visits the resort, Dan has aged into a calmer and more laid-back individual, though his capacity for a powerful, island-shaking yell remains when he is pushed to his limits.

Dan's primary motivation stems from his deep care for his Pokémon, a female Sealeo. He first encountered Sealeo fifteen years before the series when she was a Spheal that unexpectedly jumped into his fishing boat and refused to leave, leading him to adopt and raise her. As she evolved and grew larger, Dan began to worry that he could no longer properly care for her in his cramped city apartment, believing she would be happier with more space to play. This concern drives his initial action in the story: he attempts to leave Sealeo at the resort, boarding a departing ship to abandon her there for her own well-being. After being confronted and understanding the pain this causes, he accepts a position as a concierge at the resort so that he can stay with Sealeo while she enjoys the island's expansive environment.

Dan's key relationships include his nephew Tyler, who holds a position on the resort staff and advocates for him, and Haru, the main concierge who becomes his teacher and colleague. Despite Haru's anxieties about being a good instructor, Dan is grateful for her guidance, showing respect for her thoughtfulness and skill in caring for Pokémon.

Throughout his role in the story, Dan demonstrates several notable abilities. He is a quick learner, immediately mastering tasks like riding a scooter and applying lessons from Haru. He has a natural talent for attending to Pokémon's needs, such as noticing when Magikarp are uncomfortable in cold water and guiding them to a warmer area. He can also train his Sealeo to perform tricks and can command her with a whistle. His most striking ability is his powerful voice; a single, loud yell from him is enough to immediately stop a fight between two rampaging Metagross, though it also terrifies the other nearby Pokémon. This moment highlights that despite his gentle and attentive nature, he still possesses the intimidating presence from his younger days.
