Lillie

Lillie is a young girl with green eyes and platinum blond hair, with two braids at each side of her face. She wears a large white hat, with a blue ribbon around it. Lillie wears a white dress with transparent outlines, a pair of long socks and white shoes resembling ballet flats. She also carries a round bag with a Poké Ball design on both sides. As later revealed, Lusamine made the choice of Lillie's dress for her, likely with the intent of resembling a Nihilego given her obsession with that species of Ultra Beast.

After realizing her mother is too far gone to listen to reason, she temporarily changes her outfit to a white sailor-like shirt with a blue ribbon and a very short white miniskirt with a light blue line. She stops wearing her hat, instead restyling her hair as a ponytail tied together with a braid. She also wears a pink backpack with a white ribbon and white penny loafers with white ankle socks. While she returns to her original style after rescuing her mother, Lillie wears this outfit until the Alola League was over. She also wears a white Z-Ring with a red strap that once belonged to her father with an Icium Z.

In "Dummy, You Shrunk the Kids!", she retains her hairstyle from her second outfit while wearing her original style. She also tied up her hair when she was helping out at Mallow's family restaurant in "A Recipe for Success!".

Other outfit

When she goes swimming, Lillie wears a light blue two-piece swimsuit covered with sea shell braids. As later revealed, Lusamine made the choice of Lillie's dress for her, likely with the intent of resembling a Nihilego given her obsession with that species of Ultra Beast.

As a member of the Ultra Guardians, Lillie wears a pink and white Ultra Guardian uniform with light pink accents as the edge of her short sleeves, collar, and the in lines of her uniform is black with matching pink gloves. She retains her hairstyle from her second outfit.

For her goal to find her lost father, Lillie wears a white vintage dress with light blue accents and a light green ribbon around her waist. Her hat contains a light blue ribbon hem and a white lily on the knot of the bow. She wears her hair with the braids tied at the back with a light green ribbon. She wears her father's Z-Ring on her left wrist and a pair of white gloves with spiky cuffs.

Lillie is a girl who loves Pokémon but was unable to touch them after moving away to another mansion with her mother and brother after an accident with an Ultra Beast. Upon her return, she inexplicably was frightened of Pokémon and will either jump away or freeze like a statue though some feel that she is terrified of them. Despite her fears, Lillie loves to leave food out for various Pokémon to eat. Her knowledge of Pokémon is top notch. Lillie was so scared of touching Pokémon that she had to wear a suit to ride Pokémon. Lillie decided to take one step at a time to get over her fear of touching Pokémon. Initially, she was only comfortable with her Alolan Vulpix Snowy, but managed to touch Ash's Pikachu without hesitation later on, and even hop on a Stoutland without repercussions. However, after her memories came back regarding Silvally saving her, she was able to touch all Pokémon without being scared.

She has a keen eye to detail which was shown when she noticed the details in the recording tape of Rotom's and proved Kiawe's innocence. Lillie is rebellious towards her mother Lusamine upon their reunion and like Brock, she also shows her anger and disdain because of her ditzy behavior and also causes a fall out between the two and became annoyed when she keeps doting on her. After rescuing their mother from the Ultra Beasts onward, Lillie grew more confident in herself shown in "Not Caving Under Pressure!" when she teamed up with medium-sized wild Alolan Sandshrew in a Double Battle with Snowy against a wild Tyranitar.
