Rules: it has to be something about carnagetale or maybe other genres of tales like Carnagefell or carnageswap something like that but it has to have carnage in the name
other than that do whatever you want
so basically this au
its like a mixture of (Dusttale underfell and horrortale, undertale . but the reason its named CarnageTale is because monsters hate each other and humans, the strongest must survive but that doesn't mean you can't become friends with the strongest, so everyone in this au is edgy, creepy looking but live in a kinda peaceful town those who disobey die those who do not stand in order ...die but sans on the other hand is brothers with papyrus the great which papyrus is in the royal guard papyrus will kill those who disobey but he still respects his brother sans, on the other hand sans does love his brother but he also feels bad for the townsfolk since well he goes to grillbys alot he tries to cool down papyrus's temper well it does work since papyrus is kinda obsessed with his brother but papyrus only cares about undyne, himself and sans and he's killed people before.. but sans well he's just a sad skeleton boi with a hard past his brothers past was pretty messed up too even though papyrus does some messed up things he still forgives him they both love each other as brotherly beings sans actually cant live without his brother since he is tired mentally and physically and is depressed
papyrus is also depressed but but not as much as sans since sans went through more than he did (the only reason papyrus joined the royal guard is so that he can be feared so he can protect his brother, papyrus is doing it for sans, and undyne his friend who is ill she wants to give papyrus her job as captain since she doesn't know when she will die so papyrus is sad even though he was taught the weak must die he still cant kill her even though she wants him to (so in this au undyne gets mad and tries to kill sans because she is trying to pressure papyrus into killing her to take her rank and XP. like in this world kill or be killed truely qualifies
if your confused about this au well imagine it like underfell except everythings purple and not red, and people are less edgy, but are creepy as horrortale. and act like undertale. and the dusttale part, well people kill each other and get powers from others they killed, kinda like in dusttale.
