Frozen AU

Frozen AU is a relatively new AU, in which the characters of Frozen  are replaced with the Big Four. This could also a sub-scenerio for Fairy Tale AU and Elements AU.

About the AU
This AU was created when a fan thought that the characters of Frozen fit the Big Four.

Rapunzel Corona
In this AU, Rapunzel usually plays the role of Anna. When Rapunzel and her older sister Merida played their favorite game, "camping", they did stuff like climbing the marble columns (trees), building mud people (mud equivalent of snowman) and etc. While setting a campfire Merida accidentally shoots a small fireball at Rapunzel when she was setting a campfire in the ballroom, this causes Rapunzel to gain a small brunette strand of hair. They brought Rapunzel to the Troll King and healed but erased the memories of Merida's powers. Rapunzel desperately wanted to play with Merida again but Merida keeps shutting her out in fear of her powers. When the King and Queen died, Merida was so shocked she burned her room and almost set the whole castle on fire. There have also been fans that have placed Rapunzel as Elsa, with fire power instead of ice due to her connection with the sun.

In the Genderbend AU, Rapunzel plays either Hans or Olaf.

Merida DunBroch
In this AU, Merida usually plays the role of Elsa, except rather than ice powers, she would have fire powers. In their young years, Merida accidentally struck Rapunzel with her fire powers. After Rapunzel's memories have been changed, Merida had kept herself as a shut-in, not wanting to hurt her sister any further. (Sometimes, the roles of Rapunzel and Merida are inverted [Rapunzel plays Elsa and Merida plays Anna].)

In the Genderbend AU, Merida plays the role of Kristoff for her sometimes rough, but caring, personality.

Hiccup Horrendous Haddock III
Hiccup, usually, although to much surprise, plays the role of Hans - the deceitful prince of the Southern Isles. Hiccup would meet Rapunzel after her 'First Time in Forever' song. Rapunzel and Hiccup soon 'bond' during Merida's coronation ball, he proposes to her and she gladly accepts. When Merida hears about this, she refuses to give her blessing; but Rapunzel, in fear of spending the rest of her life trapped again, causes a heartbroken uproar. After Merida exposes her powers, Rapunzel leaves Hiccup in charge of the kingdom. His true nature is soon revealed when he and Rapunzel are alone. In the end, Rapunzel punches Hiccup and he is sent back to his kingdom awaiting for his punishment. Fans often use Eugene in this role instead.

Sometimes, in the AU where Jack is Elsa, Hiccup will play Anna. He is sometimes portrayed as a friend of Jack, rather than a brother. Rarely, Hiccup plays the role of Kristoff, a character that many fans argue Hiccup would suit better than Jack due to the similar relationships with an animal (Kristoff with Sven; Hiccup with Toothless), and being isolated from people at a young age. Are have also been fans that have placed Hiccup as a fire and male version of Elsa.

Jack Frost
Jack usually plays the role of Kristoff, the love interest of Rapunzel (who plays Anna), which is fitting since Kristoff was an ice harvester in Frozen. Sometimes, Jack will play the role of Elsa, since he has similar powers. On occasion Jack plays the role of Hans due to his appearance.

Tinker Bell
Being a warm season fairy, having a winter fairy sister, dressing up warm for her cold environment, determined to keep her sister by her side, being healed by her and given "ice-skates" from her, casts Tink as Anna. With Terence as Kristoff, Cheese as Sven and Blaze as Olaf.

Periwinkle
Being a winter season fairy, having a warm season fairy sister, wearing a icy blue dress, caring about her sister's wellbeing in the cold and helping her with ice-skating, casts Peri as Elsa.

Hiro Hamada
Because of Hiro being a younger sibling that cares about his older siblings, he can be cast as a male Anna. While there have been fans that have portrayed him as a younger, male version of Elsa, from when he locked himself up from the world and its people for a short time after Tadashi's death.

Tadashi Hamada
Since Tadashi is an older sibling that cares about his younger sibling, he can be cast as a male Elsa. While there have been fans that have him cast as Hans (for his appearance) or a male version of Anna.

Astrid Hofferson
For the Hiccstrid pairing, that has Hiccup as Kristoff, Hans or a male Elsa, Astrid is seen as Anna. With her leaving her cursed home to go in search for her childhood friend and get him to set things right, as there is Frozen AU fanwork of the ship that has Hiccup and Astrid as Elsa and Anna-like characters that are in love with each other, instead of being siblings.

Joy
Due to Joy being full of life and with Sadness commonly seen as Elsa, fans portray the yellow emotion as Anna. She has also been placed as Elsa.

Sadness
Due to Sadness's blue clothing, turning certain items blue and with Joy commonly seen as Anna, fans portray the blue emotion as Elsa.

GoGo Tomago
When Honey Lemon is seen as Anna, fans portray GoGo as Elsa. As Elsa is commonly seen as GoGo or is placed in her hero armor or civilian clothing in Frozen/Big Hero 6 and superhero related fanwork or for crossovers.

Honey Lemon
When GoGo is seen as Elsa, fans portray Honey Lemon as Anna. As Anna is somtimes seen as Honey Lemon or is placed in her hero armor or civilian clothing in Frozen/Big Hero 6 and superhero related fanwork or for crossovers.

Bing Bong
Bing Bong's time traveling with Joy and Sadness, and with the two emotions seen as Anna and Elsa, Bing Bong is cast as Olaf.

Anger
Fans have cast Anger as a male, flame version of Elsa for fun. Along with the role of Hans.

Fear
Fans have cast Fear as a male Anna for fun. Along with the role of the Duke of Weselton.

Disgust
Fans have cast Disgust as Anna, which might be due to the green dresses that Anna wore throughout her childhood and at her sister's coronation; and with most of them having flower-like patterns and design to them. Much like Disgust's dress, as it is both green with flower patterns on it. Fans have also cast her as a female Kristoff for fun.

Wreck-It Ralph
Due to the Icebreaker pairing, when fans sometimes have Ralph and Elsa switch clothes for fun, it also has fans portraying Ralph as a male version of Elsa. While Felix is featured as a male Anna, beside him.

Vanellope von Schweetz
Due to the Elsanellope pairing, when fans sometimes have Vanellope and Elsa switch clothes for fun, it also has fans portraying Vanellope as a younger version as Elsa. Or have an older version of Vanellope for the role.

Fix-It Felix, Jr.
When Ralph is featured as male version of Elsa, Felix is cast as a male version of Anna.

Baymax
Since the Bayelsa pairing sometimes has Baymax placing in Elsa's clothing, along with having a blond wig on his head, and the Hirelsa pairing sometimes featuring Elsa as a Baymax-like character to Hiro, Baymax can be portrayed as Elsa; for fun. While his large white body sometimes has Baymax as a friendlier version of Marshmallow, or have a mini version of the robot as a Snowgie. As one of the Snowgies as a Baymax-like face and eyes, as a Big Hero 6 Easter egg in the Frozen Fever short.
