Darknest

Darknest (ダークネスト) is the main antagonist of Star☆Twinkle Pretty Cure and the leader of the Notraiders. In episode 46, Darknest is actually a Star Princess called the Ophiuchus Star Princess (へびつかい座のスタープリンセス).

Appearance
Darknest appears as a tall humanoid wearing a long cape, whose snake-like features are based on the Japanese yokai Uwabami. Darknest's face is hidden in the shadows with her voice distorted to hide the fact that she is actually a Star Princess.

As the Ophiuchus Star Princess, she has long wavy emerald green hair that reaches her feet, held up in several purple bands with two long crimson strands in the front. Her eyes are bright yellow with green pupils that also have glowing red stars in them.

She wears a strapless dress with dark indigo and light purple bodice that is lined with gold at the top along with a feathery purple collar. The skirt is floor-length and purple with a dark indigo layer over it. Along the middle is a white section decorated with light purple oval-like designs and an indigo border.

Her accessories include a gold halo-like tiara that resembles a snake, a gold choker, gold crescent-shaped earrings, a wrap around her arms that resembles a bright green snake, and two gold bands on her upper arms. She later takes Garuouga's bracelet.

Personality
Darknest is very serious and power hungry, and desperately wants the power of the Star Princesses and Fuwa. Darknest also neglects her minions' well-being and regards them as pawns. When she can't receive the desired results she hopes for, she is willing to finish off anyone whom she deems as obstacles with violence.

She also loathes imagination because she regards it as a failed product of the universe. This is due to her being a pessimist who firmly believes that imagination can bring negativity (which is partially true though) and how the 12 other Princesses exiled her after they didn't comply to her wish.
