Lusamine

Lusamine is a main antagonist in Pokémon Sun and Moon and a supporting character in Pokémon Ultra Sun and Ultra Moon. She is the president of the Aether Foundation.

She is voiced in the anime by Sayaka Kinoshita.

Appearance
Lusamine has blonde hair with silver streaks and green eyes. She wears a white dress with a diamond badge on it, black and white leggings, and boots of the same color, with green soles. Her boots have a medium-height yellow heel to them.

When Lusamine fuses with a Nihilego, she transforms into a dark-colored version of the Ultra Beast with her upper torso in the bell, her legs hanging out of the body and several eyes on her tentacles with gem-shaped pupils.

Personality
Lusamine was originally shown to be a kindhearted lady who is willing to "create a utopia for Pokémon". In truth, however, she seeks for beautiful things she could "own". Though her daughter and son both try to warn her about the dangers, Lusamine does not forgive them for betraying her, showing utter coldness, as she does not want anything to stand in her way to obtain the power from the Ultra Beasts. Ultimately, she wishes to live in a world that consists only of her and Nihilego, which she views as a surrogate family that is completely obedient to her. She is also extremely manipulative, taking advantage of Guzma's inferiority complex to befriend him and convince him to serve as a hidden mercenary for the Aether Foundation.

Despite this, it is implied that Lusamine was a genuinely kind person at one time, but after her husband Mohn was lost in the Ultra Beast's world, the grief drove her insane. After her defeat and forceful separation from her Nihilego, she seems to regain some of her sanity and comments that she finds Lillie "beautiful," before collapsing into a coma.
