Lillie is Ash's classmate at the Pokémon School. She's the daughter of Lusamine and has an older brother, Gladion.
Early on, she can't physically touch Pokémon—something that stems from a traumatic event in her past. This becomes a major part of her character arc as the series progresses, and fans often note how meaningful her gradual breakthrough with Pokémon becomes, especially through her bond with Snowy (Alolan Vulpix).
