Lusamine

Lusamine is a character appearing in Sun and Moon. She is the president of the Aether Foundation.

Appearance
Lusamine is a young woman with blonde hair and green eyes. She wears a white dress with a diamond badge on it, black and white leggings and boots of the same color.

When she fuses with a Nihilego, she transforms into a dark-colored version of the Ultra Beast with her head in the bell, and several eye-like jewels on her tentacles.

Personality
Lusamine is 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 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. She also has no problem tricking her employees into taking Nihilego venom to increase their power, causing them to grow extremely suggestible and cult-like in their devotion to her (with the exception of Wicke, who realized that the venom was likely unsafe and quietly disposed of her dosages).

Despite this, it is implied that Lusamine was a genuinely kind person at one time, but after her husband was lost and likely killed in the Ultra Beast's world, a combination of grief and Nihilego venom 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 "cute" again before lapsing into a coma.

Games
Lusamine welcomes the player character and others into the Aether Foundation.

However, once her plans are exposed, she prepares to open a wormhole to the other world, where the Ultra Beasts originate from. Though her son and daughter try to stop her, she has Guzma try to attack them, She succeeds in opening the wormhole and vanishes.

Once the player character and Lillie access the Ultra Space, Lusamine still refuses to back down, claiming she has the right of taking control of Ultra Beasts and ignore Lillie. Lillie gathers her strength and opposes Lusamine, who fuses herself with a Nihilego, which causes her normal Pokemon to develop Totem traits (likely due to the Nihilego venom). However, the player character defeats her, while Lillie calls on the power of Alola's Legendary Pokémon, causing Lusamine to become hurt and split from the Ultra Beast.

In the end, Lusamine was taken away to recuperate, while her daughter seeks ways to heal her.
