UnderApocalypse(Work In Progress)

An out break. A terrible disease that cause it's symptoms to grow aggressive amounts of sharp teeth and behave like a wild hungry animal, eating any living thing the infected sees. The disease however, did not affect monsters. Only humans could. This becoming a widely known fact, the humans stormed Into monster Ville and take monsters in order to find a cure or at least a treatment. Many monsters were able to escape the grasp of the humans due to their power, but not all. The humans were able to capture ten monsters. Those monsters including Toriel, Monster kid and Papyrus.

Sans undyne and frisk are now on a mission to retrieve those they care about from being harmed. They can only hope nothing has happened to them yet...
