Dark AU

Dark AU (also known as the Evil Four) 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 changed into darker versions of themselves. As it is not canon, ideas for this AU are shown through fanfiction, fanart, and other fan-made works.

About the AU
In some fanfics, either Jack Frost from Rise of the Guardians, Merida from Brave, Rapunzel from Tangled or Hiccup from How to Train Your Dragon  are changed into a dark version of themselves, usually by Pitch Black, making it a Seasons Guardians scenario on Pitch's side of the conflict. This may sometimes cause much conflict and destruction among the members of the team. Some fans also indicate that the Big Four run into dark counterparts of themselves.

The choices in each of their films define who they are, and fanfic writers like to imagine what they would be like if they took the road not taken.

Hiccup Horrendous Haddock III
The Dark Spirit of Betrayal, supposed to be Guardian of Change, Element of Earth/Air, and Spirit of Autumn. Out of all the Big Four, Hiccup's place in Dark AU has been explored the most. The most common scenario portrays him as simply a victim of prejudice for the sake of his dragon and branded as an Outcast by his tribe, leaving him bitter and vengeful (often called Outcast Hiccup or Hiccup the Outcast). Other cases show that the loneliness and alienation inflicted on him by his tribe and his father left his mind in a fragile mental state, leading to murder or some degree of sadism to those who would be considered his friends and family.

Jack Frost
The Dark Spirit of Mischief, supposed to be Guardian of Fun, Element of Water, and Spirit of Winter. In the film, Pitch gives Jack an offer to join him in his crusade of extinguishing the hope and light in children, allowing him to be believed in. He appeals to Jack through the shared loneliness they have and, in this AU, rather than rejecting the offer, he joins with Pitch instead. He becomes an enemy to the Guardians and slowly grows into an infamous figure in folklore of the mortals, children of the world knowing him not from the joys of a snowday, but through the harsh and bitter cold of an unforgiving part of the year. Jack has two recurring designs; he either wears a black version of his hood, his skin, hair and eye colors matching that of Pitch (better known as the comedically named Jack Black), or his hair and body is covered in spiky icicles like a fur coat, almost as if his humanity was slowly being consumed by his squandered power (appropriately called Icicle Jack).

Merida DunBroch
The Dark Spirit of Chaos (or Misfortune), supposed to be Guardian of Courage/Freedom, Element of Fire, and Spirit of Summer. Many have made the observation that Merida's situations parallel Mor'du, and that she would be just like him if she did not mend the bond. Not only would her mother and brothers stay as bears forever, but the four clans would devolve into war and destroy themselves, much like Mor'du and his brothers did to their kingdom.

Rapunzel Corona
The Dark Spirit of Doubt, supposed to be Guardian of Creativity, Element of Air/Earth, and Spirit of Spring. Instead of being kind and tolerant of Gothel's imprisonment, she grows bitter and vengeful, losing the sweet spirit that she had in her original storyline.
