RWBY AU

RWBY AU is a recently made AU (Alternate Universe), where the Big Four (Rapunzel, Merida, Hiccup and Jack Frost) are either replacing team RWBY or added to the current RWBY universe; however, it can also be possible that it is from an entirely different yet the same universe where the RWBY cast simply do not exist at all. Because it is not canon, ideas for this AU are shown through fanfiction, fanart, and other fan-made works.

About the AU
In the RWBY world, in the country of Vale (or another country), Rapunzel, Merida, Hiccup and Jack Frost are students who are newly enrolled in the prestigous combat school, Beacon Academy in order to fight the Grimm, mysterious, monsterous and other-worldy creatures (possibly created by Pitch) as well as other entities - such as Roman Torchwick and Cinder Fall or the rebellious faunus organization, the White Fang.

Jack Frost
Sometimes portrayed as the alternative ' Ruby Rose ' of the fandom, but can also serve as the leader of the team sometimes. He can also possibly be the alternative ' Weiss Schnee ' of the fandom- despite the differences of their personalities, their affiliation with the winter season or snow element is quite the same.

Hiccup Horrendous Haddock III
Similiar to Jaune Arc (as both are smart and good in leadership but bad in physical combat and such), but can also serve as the leader of the team sometimes.

Merida DunBroch
Similiar to Pyrrha Nikos (the two are red-heads, beautiful and are very excellent in combat), but can also serve as the leader of the team sometimes.

Rapunzel
Portrayed as the alternative ' Yang Xiao-Long ' (possibly due to blonde hair and/or similiar personality), but can also serve as the leader of the team sometimes. She can also be the alternative ' Ruby Rose ' (if not Jack Frost) of the fandom, due to their similiar hyper, friendly, and perky attitude.
