Bio
Lillie is a girl that loves Pokémon, but is unable to touch them because she was attacked by an Ultra Beast. Gladion was so terrified he wasn't able to save her but Type: Null saved them. Lilie had never mentioned anything about this to Ash or her friends because she couldn't remember as that experience frightened her that badly.
Her knowledge of Pokémon is top notch. She first met Ash at the Pokémon School on Melemele Island when she tried to warn him to avoid the Tauros.
Silvady is a Pokémon that was created to defeat Ultra Beasts. Gladion didn't want to go into detail about its creation but he explained to Ash that nobody must know about Silvady's existence. After Lillie was captured by Faba to wipe her memories again, Gladion's Type: Null broke through its helmet they had been trying to take off to reveal that it was a Silvady. It once again fought Faba and rescued Lillie. Lillie remembered what had happened before and thanked Silvady for rescuing her and gave it a hug, touching it and finally getting over her fear of touching Pokémon now that her memory was restored.

Snowball was raised by Lilie after the egg was given to her to care for by Principle Samson Oak. The egg was brought to the school from where it was found on Mount Lanakila.
After the Pancake Race, everyone was at the Pokémon School to watch it hatch into Alola Form Vuplix. Lillie said she had already named it Snowball and that the name came from the fact that it is white as snow and often rolls around like a ball.
