Final Fantasy AU

Final Fantasy 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 play roles of the characters or their job classes from the 15 (and many more to come) Final Fantasy games. This can be considered an offshoot to Fairy Tale AU, Sci-Fi AU and Arcade AU.
