Elements AU

Elements AU is a popular AU (Alternate Universe) within the Rise of the Brave Tangled Dragons fandom. In the AU, Rapunzel, Merida, Hiccup and Jack Frost are all associated with a certain element, and usually have magical or supernatural powers as a result. Because it is not canon, ideas for this AU are shown through fanfiction, fanart, and other fan-made works.

About the AU
The Big Four are usually born with, associated with or granted power over one of the four elements. The placement of each individual is somewhat debated throughout the fandom. Because Queen Elsa fits in with this concept in-canon, artists and writers like to experiment with her the most.

Hiccup Horrendous Haddock III
Hiccup is most often portrayed as having a connection to Earth. He has brown hair and green eyes, which are colors commonly associated with the outdoors. He has a steady, dependable nature, and brought change to his Tribe, just as the earth is always slowly changing and making things better. However, some people have made arguments that Hiccup would be better suited to '''Wind. '''Wind also brings change and is hard to control or transform, as Hiccup establishes his individuality among the members of his Tribe. His ability to train and ride dragons also suits him well for this element.

Jack Frost
Jack is usually related to Water or '''Ice. '''Being an immortal winter spirit, he would already possess formidable snow and ice powers. He is also unflappable and easygoing, traits that personify the free-flowing nature of water. Occasionally people give Jack the power of Wind as well, because of his ability to ride the wind, free spirit and unwillingness to become a Guardian and bind himself to any cause.

Merida DunBroch
Merida is almost always shown as having the element of '''Fire. '''Her wild red hair dances likes flames and she has an extremely volatile personality, completely averse to following orders or conforming to others' standards. A smaller portion of the fandom sees her as the opposite, Water, since it is flowing and unrestrained.

Rapunzel Corona
Rapunzel is sometimes depicted as having Wind powers. Her long, golden hair reflects the flowing currents of wind and she has a free personality that cannot be contained within the walls of her tower. On the other hand, she also seems suited to be connected to Earth on account of her green eyes, healing powers and loving, caring nature. She is also occasionally portrayed as Fire, due to her connection to the sun, although this is not one of the more popular choices.
