Ice Queen

The Ice Queen is the new ruler of the Ice Kingdom and she is the female and more evil version of The Ice King. She is the main villain in Adventure Time with Fionna & Cake.

Personality
The Ice Queen is far more cruel, evil, aggressive, and arrogant 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. She is more serious than the Ice King, but like her counterpart, she inevitably fails.

Trivia

 * In Natasha's drawing, Ice Queen was the previous owner of Cake, who cared for her as a kitten.
 * The Ice Queen refers to Fionna as a "tomboy."
 * 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.
 * While the Ice King is always barefoot, the Ice Queen wears shoes.
