PREMISE: after a genocide route flowey goes to asgore and tells him about the human. asgore understands that this flower knows more than him, and entrusts him to give the human souls to whoever he deems fit. thus, this au. after defeating asgore, he gives both his human and monster soul to flowey so he can go to the surface and escape, but flowey goes to the surface and takes down 6 more humans becoming his hyperdeath form. however, the human is stronger, they were able to defeat 6 Ensouled Monsters, what's one more gonna do?
PREMISE: 3 years after the Monsters were trapped underground. W. D. Gaster, the Royal Scientist, under the nose of his lab assistant, Alphys, made a breakthrough. The Power of Dog. It far exceeds the power of a human soul. The power of 6 monster dogs, is stronger than that of 7 human souls. With this information, Gaster performed experiments on the monster dogs, eventually removing their souls entirely, replacing them with determination to keep them alive. The queen, Undyne, was not aware of how Gaster had obtained these souls, but what she did know was that the barrier was near breakage. However, the canines, missing their soul and having only determination, had grown into horrid abominations. Alphys had encountered one, and in his quite literal blind rage, he blamed her for their fate. Alphys, stricken with horror and grief, fled to the Ruins. Meanwhile, one dog monster was able to escape the laboratory before they could lose their soul with the help of their lover. They both knew the dog was not going to survive if they stayed in the underground, so the lover gave their life for the dog monster to cross the barrier for a better life on the surface. Papyrus Gaster, the new royal scientist, had attempted to recreate his fathers work after he had retired, in order to find a way to reverse it and fix the dog experiments. He added determination to a soulless object, a mushroom from the barrier, to see its effects on it. One day, the mushroom disappeared. The lover was reincarnated as that mushroom and, stricken with grief for the love of their death, they had made friends with Asgore and Toriel, under the new name Ragel, while they were at Nick’s Nice Cream Parlor. In the meantime, 8 humans had fallen into the underground, and since the fact human souls could open the barrier was lost the times, they were drafted as royal guards by the captain, Sans, (who was only put in power because Papyrus begged the queen to make him) and lead by Asriel. Papyrus, eager to help someone in need, created a body for a ghost named Madra, now Madroid, who soon became a celebrity in thee underground, even having a resort, multiple tv shows, and a restaurant chain. Meanwhile, Ragel was in grief. It had been so long, Ragel had even forgot everything about their long lost love but their face. The dog monster, in disguise on the surface, falls into the underground on an annual walk to their lovers grave
PREMISE: so i was thinking about how many undertale aus had sans as the literal only character. so i had the idea to make an au where each member of the cast was from a different au. But i decided to make the Frisk be from an au made by me. so introducing Corpse Flower! in a neutral fight (bc pacifist and genocide are too common) frisk (with charas ghost) was fighting flowey (with the 6 souls) and losing. however, in some way (idk yet) they fused. my current ideas are that the 6 souls forced omega flowey to help and then somehow that happened, or flowey having souls caused him to regret?? iunno ill keep it vauge until i figure it out. anyway this aus pretty foggy rn but ill keep yall updated. oh also kris from deltarune is in the main cast for an unexplained reason
