Ice Queen

Ice Queen is the gender-swapped version of Ice King, created by the original series designer, Natasha Allegri. She has winter/ice-related powers like Ice King. She will be in "Adventure Time with Fionna and Cake". Ice Queen captures men, while Ice King captures women.

Natasha Allegri has stated that the Ice Queen is far more cruel and evil than the Ice King. Supposedly this is to counteract the fact that she is also far more physically attractive than her male counterpart, aside to the fact that she is female, being physically attractive is the only difference between the two.

Appearance
The Ice Queen has blue skin, long white hair and lightning-shaped eyebrows. Her hair somewhat resembles the Ice King's long white hair and beard. She wears a small gold crown with red gems on her head, similar to the one Ice King wears, and gold necklace with blue gems on her neck. She also wears a large blue dress, instead of a tunic.

Trivia

 * The Ice Queens final designs differ from that of her initial designs, 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".
 * It is possible that the Ice Queen's powers are stored in her crown or possibly her necklace.
