Janna

Janna is the het ship between Anna and Jack Frost from the Frozen and Rise of the Guardians fandoms.

Canon
Anna and Jack never meet due to Jack being a DreamWorks character, while Anna is a Disney character.

Due to magical intervention, both of their brown colored hair were turned to a shade of white. Anna was hit accidentally by her older sister's ice magic, twice, and Jackson Overland being reborn as the winter spirit and future Guardian of Childhood, Jack Frost. Jack's human-to-spirit transformation began shortly after the Man on the Moon witnesses Jack saving his little from falling into an icy lake, all white easing her fears and worries with fun. While Anna sacrifices her chance to unfreeze her heart so she could save Elsa from being killed by Hans, the love that the sisters have for each other allows Elsa to bring Anna back from her frozen state.

Both Jack and Anna have been lonely for many yaers, since Anna was separated from Elsa and Jack was invisible to those who did not believe in him. After Anna was separated from Elsa within the castle, she tries to invite Elsa in fun activities that they could do together as they grew up, even though Elsa kept turning them down and Anna away. While Jack's unbelieved state has him being invisible to others and has tried to bring become believed in by using his ice powers to start fun games and activities to children by bring them snow days, and even though he gives them a fun time in the snow his efforts were in vain until he helps a young boy from losing his belief in the Easter Bunny and the other Guardians. The two have also been in a situation where they lost hope in a place that they were trapped in, until their restored hope allowed them to escape so they could help their friends and other innocent.

Fanon
The crossover pairing is one of the het ships of the Rise of the Brave Tangled Frozen Dragons fandom and its sub-fandoms. It isn't very popular as Jelsa is, but there have been fans who rival the two RotG/Frozen ships with each other. The ship romantic side of the ship is commonly shipped alongside the more popular Hiccelsa.

As part of the Rise of the Brave Tangled Frozen Dragons fandom, the ship is commonly featured in AU scenarios. One example is a Peter Pan AU with Jack as the titled character and Anna as Wendy. Another example being a Viking AU, since many manip fanart for the AU sometimes has them in Hiccup and Astrid's viking clothing, in which sometimes has fans casting Jack and Anna as the main het HTTYD couple. There has also been simply kind of fanart that sometimes places Jack in Hans' clothes, as himself and not as a Hans-like character, for the Arendelle setting of the ship. While the Rise of the Guardians setting and side of the ship has Jack protecting Anna from Pitch Black. Like Jelsa and Jackunzel, some works show Jack meeting Anna as a child and having a girl-imaginary friend relationship. Due to the modern setting in Rise of the Guardians compared to Frozen, Anna is sometimes portrayed with the more modern looking clothes that her Netizen version wears in Ralph Breaks the Internet. Netizen Anna could also hang out with a fanon Netizen version of Jack from a DreamWorks website, or could have Anna wear those clothes in a Modern AU with Jack.

While AO3 only has 14 fanfics on the ship, Janna has a reasonable size fanbase on both DeviantArt and Tumblr.
