Helsa

Helsa is the het ship between Elsa and Hans from the Frozen and Once Upon A Time fandoms.

Frozen Fever
When Elsa blow the horn as part of Anna's birthday celebration, while coming down with a cold, Elsa sneezing while blowing the horn at the same time had caused a large snow ball to make its way all the way from Arendelle to the Southern Isles, where it lands on top of Hans. While mugging out the horses, as his punishment for what he tried to do to Elsa and her family.

Frozen II
When Elsa knew that she has to make her way to the Enchanted Forest her father had told her of, Anna mentions Hans among the list of things she faced three years ago. Shortly after finally Elsa reaches Ahtohallan she uses her powers to destroy the frozen water memory figure of Hans, from a moment when he met Anna, without a seconded thought. Due to Elsa and Hans parting on bad terms with one another.

Fanon
Because Hans had originally planned to win Elsa's heart to gain her kingdom's throne, before making Anna as his more earlier mark, along with Anna ending up with Kristoff, many fans had presume that Hans would move onto Elsa before his true colors were revealed. Despite Hans being the main antagonist of Frozen, it hasn't stop fans from shipping Elsa and Hans together, and have even shipped Helsa beside Kristanna and Eugunzel in the Frozen Tangled crossover fandom. Helsa and Hanna could even be due to fans who enjoy shipping Disney Princesses and Heroes with their Villains, which gives the two ships, as well as Hansoff, support in the Disney Frozen fandom.

The ship's support grew once the two characters and the world of Frozen was added to the Once Upon A Time series, which adds the Frozen ship to its OUAT fandom.

As part of the Rise of the Brave Tangled Frozen Dragons fandom, the two are often featured in AU scenarios. One example of this is a Zootopia AU where Elsa and Hans are cast as human-animal hybrid version of Judy Hopps and Nick Wilde. There have even been AUs where Hans is given power over fire, which is Elsa's opponent element.
