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, from Anna being hit accidently 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 in 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, and the love that the sisters have for each other allowed Elsa to bring Anna back from her frozen state.

After Anna and Elsa were separated from each other within the castle, Anna 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 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.

Similarities and Comparisons

 * The two conflicting personalities could definitely lead to some very interesting interactions and tensions.
 * Others try to argue that Jack is over 300 years old, compared to Anna who is only 18/19 years old. This is a popular trope in fiction pairing an immortal with a mortal (as an immortal vampire with a simple mortal human), the tragedy of their separation through the test of time a prefereabl tool for drama and tragedy.

Fanon
The crossover pairing is one of the het ships of the Rise of the Brave Tangled Frozen Dragons fandom, sometime after it was renamed from Rise of the Brave Tangled Dragons; as well as it being apart of the Rise of the Frozen Guardians crossover fandom. It isn't very popular as Jelsa is, but there have been fans who rival the two RotG/Frozen ships with each other. While in the Frozen Tangled Guardians crossover fandom, in which adds Disney's Tangled to the Frozen/RotG crossover, Jack is featured as Anna's father; for when he and Rapunzel take the place of her and Elsa's parents.

The ship romantic side of the ship is commonly shipped alongside the more popular Hiccelsa, a bit like how Jelsa is sometimes shipped beside Hiccanna. The combination of the two pairings is often featured in the Rise of the Frozen Dragons expanded universe, which adds How to Train Your Dragon to Rise of the Frozen Guardians.

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.

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