Ice Queen

Ice Queen is the gender-swapped version of the Ice King, created by the original series designer, Natasha Allegri. She has winter/ice-related powers like Ice king, that originates from her Tiara. She makes her first appearance in the episode "Adventure Time with Fionna & Cake." She captures princes.

Personality
The Ice Queen is far more cruel, evil, and aggressive than the Ice King. She uses far more violent and complex means to get her way than the Ice King does; such as tormenting Fionna with a wild scheme in order to put her out of commission, leaving her free to obtain Prince Gumball, but inevitably fails.

Appearance
The Ice Queen has light blue skin, long white hair, and lightning-shaped eyebrows. Her hair, while also long like the Ice King's beard, is wavy with curls instead of shaggy. She wears a small gold tiara with red gems and a neck band (incrusted with a single blue gem in the center), a blue long sleeved ball gown, and light and dark blue shoes.

Trivia

 * The Ice Queen's final designs differ from that of her initial designs, and this is because Natasha wanted her dress to resemble the dresses worn by Anastasia and Drizella, the mean step sisters from the Disney film "Cinderella."
 * Like how the Ice King's source of power is in his crown, Ice Queen's is based in her tiara, which even Cake uses for an ice attack at one point.
 * The Ice Queen's eyebrows are the equivalent of the Ice King's beard, allowing flight.
 * The Ice Queen's eyebrows were inspired by the Night Elves from World of Warcraft.
 * The Ice Queen refers to Fionna as a "tomboy."
 * In Natasha's drawing, Ice Queen was the previous owner of Cake the Cat, who cared for her as a kitten.
 * Fionna warns Cake, implying that that Ice Queen's tiara makes people evil from wearing it. This would seem to resemble Ice King's origin story in Holly Jolly Secrets Part II
 * It is possible that Ice Queen's more evil personality and cunning is based on what Ice King believes himself to be like, as it was he that wrote this story.
 * According to Natasha, the Ice Queens backstory is completely different from that of the Ice King, meaning she acquired her Ice Tiara in a different way, to that of the kings crown.
