Elsa the Snow Queen is the deuteragonist of the first half of ABC's Once Upon a Time.
Once Upon a Time[]
Before First Curse[]
Alternate Timeline[]
While Emma, Killian and Marian are imprisoned by Rumplestiltskin, Killian notices a strange urn and picks it up, only to be scolded by Emma. Killian places the urn down, and after managing to summon a time-travel portal back to Storybrooke, they all enter the portal.
After Second Curse[]
Scared and confused by Storybrooke, Elsa creates a snow monster to protect her, which ends up rampaging through Storybrooke, until it is destroyed by Regina. After finding Anna's snowflake necklace in Mr. Gold's pawnshop, Elsa vows to find Anna. Putting up a wall of ice around Storybrooke which triggers a black-out across the town, Elsa meets Emma, and although Elsa seems hostile and cautious at first, they talk and relate over things. Elsa tries to take down the wall of ice when Emma and her family say that they will help her find Anna, but the wall of ice is unable to be destroyed for some reason. When Marian suffers from an icy spell that has potential to kill her, the townspeople lay their blame in Elsa, although the real culprit is Elsa's aunt, Ingrid. When Emma's powers go out of control, Elsa manages to talk Emma out of getting rid of her magic, instead telling her to embrace it as who she is. Elsa eventually becomes reunited with Anna and Kristoff, who come to Storybrooke due to the Wishing Star that Elsa possesses, although Ingrid unleashes the Spell of Shattered Sight upon the entire town. When the Spell is broken, Elsa, Anna and Kristoff return to Arendelle and reclaim the throne. With the pirate Blackbeard terrorizing Arendelle, it is mentioned that Elsa had Blackbeard's ship shrunken in a bottle, which also inadvertantly traps Ariel.
