Ice Queen

The Ice Queen is the internally fictional 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, exists only in the fanfiction written by the Ice King.

Appearance
The Ice Queen has light blue skin, long white hair, and long 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 golden tiara with red gems and a neck band 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.

Personality
Interestingly, despite being a creation of the Ice King's imagination, 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.

Origin
Natasha Allegri has confirmed that the Ice Queen has a different origin than the Ice King. This backstory was eventually revealed in the Fionna and Cake comics. It is revealed that the Ice Queen initially was a water nymph that made friends with a cat (implied to be Cake) by saving it. The nymph is eventually fatally injured and the cat helps her with a magic gem. While not explicitly stated, the gem seems to have side effects similar to the Ice King's crown and in fact is implied to be part of Ice Queens Tiara. The Ice Queen eventually manages to undo the effect of the gem by consuming a lot of heat and melting. It is unclear if she survived this. As she melts she warns Fionna to be careful when using magic artifacts. Due to the Ice Queen and Cake having a shared past, Fionna is probably adopted and raised in a different way. It should be noted that the Fionna and Cake comic canon is told by Gunter.

Comics
In Issue 16, it is revealed that Ice King created a real life, giant Ice Queen to put in his dungeon, which he abandoned 200 years ago. When they meet again, Ice Queen rebuffs him and attempts to kill Finn and Jake; however, Ice King flies through her chest, causing her to shatter to pieces. This also frees an old lady Ice King used to power her "secondary regality processor."

Trivia

 * While Ice King has a nose,Ice Queen,on the other hand,bears no nose at all.
 * 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, Cinderella's mean stepsisters from the Disney film Cinderella.
 * Just as the Ice King's source of power is his crown, Ice Queen's is 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, who cared for her as a kitten.
 * Fionna warns Cake about Ice Queen's tiara, saying that Cake "might catch her crazy." This infers that it would make her evil. It also mirrors Ice King's origin story in "Holly Jolly Secrets Part II."
 * Because the Ice King wrote this, it shows that, subconsciously, he knows of his mentally deteriorated condition, and that it all came from the crown.
 * It is possible that Ice Queen's more evil personality and cunning is based on what Ice King believes himself to be like. It is also possible that he made her like this to make him sound more tough, as it is he who wrote the story.
 * According to Natasha, the Ice Queen's backstory is completely different from that of the Ice King, meaning she acquired her tiara in a different way, to that of the king's crown.
 * She, unlike Ice King, can do a perfect imitation of Prince Gumball, while Ice King's imitation of Princess Bubblegum is horrible.
 * While the Ice King is always barefoot, the Ice Queen wears shoes.
 * There is a "Pet Society" costume of her.
 * There is an outfit of her on Ourworld.com, like all the other characters.
 * At the end of the credits for Adventure Time: Hey Ice King! Why'd you steal our garbage?!!, the screen that shows Finn and the Ice King facing at each other fades into a screen of Fionna and the Ice Queen facing each other in the same position.
 * In the original storyboard for "Fionna and Cake," Ice Queen appears with a somewhat long nose, resembling Ice King's.
 * In The Adventure Time Encyclopædia, Ice King's "trading cards" for the Fionna and Cake characters profess a deep love for Ice Queen, though this is not necessarily canon to the series.

Appearances in other media

 * Ice Queen appears in Adventure Time Battle Party as an alternate outfit for Ice King.
