DC AU

DC 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 super-powered men and women within the DC Universe. As it is not canon, ideas for this AU are shown through fanfiction, fanart, and other fan-made works. This can be considered a sub-scenario of the Superhero AU.

About the AU
This AU portrays as the four as a group of meta-humans (normal human beings embedded with extraordinary powers) that team up in a world of superheroes and super villains. As the name implies, this AU most commonly places them in Teen Titans, Young Justice  and the DC Animated Universe, though this is not required.

The world of DC has been a popular universe for fans to use for crossovers, considering the lack of restrictions the universe has on magic and powers. The Justice League in-particular is a prime place for the Big Four to appear in the universe because of a number of reasons: it has a focus of combining many powers for one ultimate goal, it allows for the use of magic and the idea of dragons, and it adds action and adventure to really spice up a story.
