Official Disney Bio
From the outside, Elsa looks poised, regal and reserved, but in reality, she lives in fear as she wrestles with a mighty secret—she was born with the power to create ice and snow. It’s a beautiful ability, but also extremely dangerous. Haunted by the moment her magic nearly killed her younger sister Anna, Elsa has isolated herself, spending every waking minute trying to suppress her growing powers. Her mounting emotions trigger the magic, accidentally setting off an eternal winter that she can’t stop. She fears she’s becoming a monster and that no one, not even her sister, can help her.
At a young age, Elsa realizes that she holds an ancient power over ice and snow which she keeps hidden from her family, even her sister, Anna. Elsa shares a close bond with her free-spirited younger sibling, however this is shattered when the two fall out. During Elsa's royal coronation, her abilities over ice are exposed to the citizens of the kingdom, causing Elsa to accidentally place a frozen curse on it, trapping it in an eternal winter. This leaves everyone utterly shocked because of a prophecy that someone will leave the kingdom in an eternal winter. Because of this disaster, Elsa goes into self-imposed exile, hiding away in an Ice Palace conjured up through her power. To protect herself and her new home, Elsa creates a fierce snowman warrior.
Meanwhile, to save her kingdom, Anna journeys off to find Elsa to restore their bond and break the curse.
Elsa is a 21 year old girl, as the Snow Queen she has platinum-blonde hair and blue eyes, very pale skin with a light dusting of freckles (a trait she shares with her sister, Anna) and a tall slender figure. She wore a cape and dress similar to her sister's, but the dress was colored dak-turquoise with gold lacing and a black top with sleeves. Her hair was kept back in a bun. She also wore gloves all the time to contain her powers.
In her Snow Queen state, Elsa wears her hair in a side braid woven with ice incrustations. She wears a cyan, off-the-shoulder dress with slightly transparent sleeves. And underneath the sleeves of her dress is a transparent cape of sheer material draped down and covered with big snowflakes.
No, you may not and I think you should go. The party is over, close the gates.
Let it go, Let it go, can't hold it back anymore.
~ Elsa, while singing her famous song "Let it go".
No, I belong here. Alone. Where I can be who I am without hurting anybody.

Contrary to how most adaptations (particularly the 1995 and 2012 versions) portray her, this version of the Snow Queen is not a villain, since the Snow Queen in the original fairy tale, though still the main antagonist was not intended to be evil. Also, the fairy tale involved an evil troll (implied to represent Satan) building a mirror which he will use to turn everyone evil, only to accidentally smash it in the process, and one of the shards ending up hitting Kai. The Queen was based on a woman Hans Christian Andersen personally hated for being shrewd and distant.
Elsa, and the Snow Queen from the 2005 anime of the same name are the only two incarnations of the character to be portrayed as heroic characters.
Elsa is also similar to Kai from the original "Snow Queen" fairy tale, who after ends up being kidnapped by the title Queen after he is unexpectedly stabbed by one of the broken shards of a magic mirror created by an evil troll which he was supposed to use to corrupt people and becoming cold and resentful, therefore prompting Gerda to try and rescue him, combined with the Snow Queen herself. In some adaptations, Kai and Gerda are an interesting case in the Snow Queen's life and interests.
If that is the case, Elsa is the first Disney Heroine to be based on a female antagonist and a male protagonist from the source material, and the first false antagonist in the lineup.
As some elements of Elsa's character simultaneously inspired by both Ice Queen and Kai simultaneously, the moment where Elsa runaway after her powers accidentally exposed which followed by winter that enveloped Arendelle was reference of when Snow Queen kidnapped Kai. In Ross's case, she actually kidnapped herself.
