You know what we should talk about. Lillie fan theories! As many of you know, Lillie's second biggest role is in Pokemon Adventures, behind her first biggest role in the games and right after the anime. Anyone who is fan of Lillie has absolutely has to read the Pokemon Adventures Sun and Moon story arc, NO ARGUMENTS. Hehehehahaha lol. Spoilers below.
In the manga, her role is actually quite sadder than her game counterpart through a simple in-depth look on just how emotionally traumatized Lillie is by Lusamine's demanding nature, treating her like a doll that can be thrown away, not a person. The manga has gave us some more details that has spawned arguably the most incredibly dark fan theory of Lillie. That she may not even be human to begin with, she's Nihilego. Although many Adventure fans doubt this fan theory will come to true, including myself, I have to admit that Lusamine has become somewhat of a monster in both the games and anime, which is kind of funny considering how chill Lusamine is in the anime. It's not just Lillie who got psychologically traumatized by Lusamine but also Gladion.
For those who don't know, Gladion finds out that Plumeria is the second-in-command of Team Skull and he mocks her for being a woman in-charge. He later admits that this actually disturbs him a bit because he admits that a woman in-charge scares him a little, Plumeria reminding Gladion of his insane mother, Lusamine, the leader of the Aether Foundation. For those who don't know why you should find this disturbing, one of the reasons why misogyny exist in some men is not because they simply just hate women or tradition but because they possibly have a horrible mother, usually a psychologically abusive mother during much of their childhood. Although Gladion doesn't hate women, the fact he has some signs of it due to his insane mother, is actually quite disturbing to readers of the Pokemon Adventures manga.
In fact, Adventures take on Lusamine is easily the darkest and most detailed take than even the original Sun and Moon version.
