Yu-Gi-Oh! AU (also known as YGO AU) is an AU (Alternate Universe) within the Rise of the Brave Tangled Dragons fandom. In the AU, Rapunzel, Merida, Hiccup and Jack Frost are placed in the world of Yu-Gi-Oh!.

About the AUEdit

In this AU, the members of the Big Four are portrayed as "Duelists" - people that take part in a monster card game known as Duels - or as "Duel Monsters" - the monsters that players summon and use in Duels. Most commonly, this AU takes place in modern times.

The YGO anime series and manga books can even make this AU an alternative with Anime AU. While the Egypt theme in the first Yu-Gi-Oh! series and the three main Egyptian God cards (along with other Egyptian themed cards) makes it an alternative with Pharaoh AU.
