The Snow Queen

The Snow Queen is a litereally cold-hearted monarch with the ability to manipulate snow and ice. Though she stayed away from most of the war, she was determined to defend her throne, nearly killing the mighty Shan Yu to defend it.

Defending Her Castle
The Snow Queen chose not to participate in the war, but was forced into it when Shan Yu and his Hun army attempted to assault her castle. Remaining perfectly calm, the Snow Queen used her mastery over the weather to fend off the attack. It literally took her just a blink to collapse a mountain down on the army, burying them beneath the snow. Though a good amount of the Huns, including Shan Yu himself survived, they chose not to assault the Snow Queen again, realizing that they were totally outmatched.

The Snow Queen's Return
The Snow Queen later found out that her enemy Shan Yu had survived his battle with her, and had conqured China. The Snow Queen has her ally King One-Eye to attack Shan Yu, although the King is qucikly defeated by him. She later sends her friend Stormella to attack Shan Yu's ally Mozenrath. Stormella is also defeated. This angers the Snow Queen, who shatters her mirror. She declares to finish Shan Yu and his alliance herself. Then, she transforms into a more powerfull form in order to defeat him.

Vs Odin
Hades, who has been observing the Snow Queen's actions, views her hatred of Shan Yu as a threat to his master plan. As a result, he enlists the aid of Odin to defeat her. When he arrives at the queen's castle, she immedeatly attempts to attack him, but is quickly subdued by Odin's abilities, forcing her to retreat. As she attempts to escape the palace on her sleigh, Odin freezes her solid. Her current fate is unknown.
