Ice Queen [Adventure Time]

The 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, which originates from her tiara. She makes her first appearance in the episode "Fionna and Cake," in which it is revealed that she, like all the other gender-swapped characters, existed as in the fanfiction written by the Ice King.

The Ice Queen has light blue skin, long white hair, and long lightning-shaped eyebrows. Like her male counterpart, she also has white eyes but with deep blue eyeshadow. Her hair, while also long like the Ice King's beard, is wavy with curls instead of shaggy. She wears a small golden tiara with red gems and a neckband bejeweled with a single sapphire blue gem in the center. She also wears a blue long-sleeved ball gown with blue buttons, and light and dark blue shoes. Her voice is high-pitched and raspy like that of a witch. She also appears to be quite tall as Fionna only reaches up to her chest.

Her human form in Adventure Time: Fionna & Cake depicts her as having olive skin and dark hair similar to that of Simon Petrikov. Her eyebrows retain their jagged shape, but are much shorter. She also wears a white uniform consisting of a collared shirt and matching pants as well as a red bow tie and a small white crown.

Interestingly, despite being the alternate version of the Ice King, the Ice Queen is far more cruel, evil, and aggressive than he is. She uses much 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, and leaving her free to obtain Prince Gumball, while the Ice King would usually break in through a window with a cheesy phrase. She is more serious than the Ice King, but like her counterpart, she inevitably fails. In the Fionna and Cake comics, she is revealed to be a quite tragic character as her schemes are all aimed at fixing her condition caused by her Tiara. That being said, the episode, "Five Short Tables", shows she does have a comical side similar to Ice King, as she also writes fanfic and almost wanted Cake to make her a flapjack portrait.

As a human, she appears to be more mild-mannered and enjoys her profession serving ice cream. Like everyone else in her world whose memories of their past lives were erased, she has completely forgotten about her feud with Fionna. Though she showed indignation at seeing Fionna climb into her cart.
