About the AU
Spawning from fanart, this AU places the Big Four, and other such characters as Hybrids and have human characters animalized (or portrayed as animals, its a bit like genderbending), while animal and "creature" characters are humanized (portrayed as humans) for pairings, crossovers and other AUs. The four also have animal-like parts (like ears and tails) on their bodies or have their abilities. The four can also be partnered up with animals, that fans sometimes portray them as.
