Biography
Lusamine is introduced as the president of the established Aether Foundation, an organisation that takes care of injured and hurt Pokémon, and lated revealed as the mother of Gladion and Lillie. At first, Lusamine is shown to be a "good lady with good intentions" and a fellow hero, but her psychotic plans are soon revealed and she betrays the player.

She is despicably evil and will do anything to get what she wants, even by fusing with an Ultra Beast named Nihilego. She had been obsessed with the mysterious "Ultra Beasts" after her husband ventured into the Ultra Space (where the creatures reside) and vanished. Lusamine dressed herself to resemble one of the Ultra Beasts known as Pheromosa, and also dressed her daughter Lillie in clothes that looked a lot like Nihilego. She accused her daughter of stealing the powerful Pokémon Cosmog from her. Recalling that Lillie once was "adorable" to her, Lusamine notes that she has now "turned ugly" due to her befriending the player, and then proceeds to place accusations upon the player. Lusamine sends out Nihilego and reaches her arms out above as it fuses with her, becoming "Lusamine-Nihilego", then battling the player with her Pokémon. After being defeated, Lusamine-Nihilego is seen to be furious. Before she is able to crush the player with her bare hands, Lillie calls out the Sunne Pokémon Solgaleo/Moone Pokémon Lunala (depending on the version), who then blasts Lusamine-Nihilego to the ground with their special powers. Lusamine-Nihilego then detach and return to normal. Lusamine collapses to the ground, visibly tired. Lillie rushes to her aid and seemingly forgives her mother, whom wonders when her daughter had "started to become beautiful".

It was later revealed that Nihilego acted almost like a parasite—it had brainwashed/possessed Lusamine and had been controlling her. When Lusamine was possessed, she acted as if Nihilego was her own child, and loved it more than Gladion and Lillie. After her defeat, Lusamine fell into a deep coma; however, she redeemed herself.

Trivia

 * She is similar to Ragyo Kiryuin. Both are obsessed with beauty, become fully devoted to creatures from other worlds, and they are abusive towards their daughters. The only obvious difference is Lusamine never sexually abused her children.
