Time Travel AU

Time Travel 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 taken through their time from their perspective eras. This can be considered an offshoot to Sci-Fi AU.

About this AU
In this AU, one or more of the main characters of the fandom are sent through time in meeting the other characters.

In the early stages of the crossover, fans were looking for ways that the four characters could possibly cross paths. If the events of Rise of the Guardians occurred in the year the film was released (which would have been 2012), and Jack had been an immortal spirit for 300 years, then the year of his death would have been 1712. Hiccup, however, would have lived much before this time because the Viking era lasted from the late 8th century to the late 11th century. The time period in which Rapunzel and Merida would have lived is less clear, though a brief mention of Vikings in Brave would mean that Merida's story probably happened around the same time as Hiccup's (700-800 A.D.) and Tangled probably occurred during the 19th century.

Because of this, some fanfic writers have come to the idea that time travel was possible, either through magical artifacts or through the meddling of magical figures like the Man in the Moon.
