So I've joined the party and created an Undertale au! I will be creating a comic series about it, but it is mostly for practice purposes so don't expect it to be that good.
In this au, Ariel confinced Chara not togo through with their plans and kill themself. So they continue living as a family, and as more humans fell they would be adopted and the Dreemurrs would grow. However, after some turmoil Toriel decides to divorce Asgore and takes all the human children with her into the Ruins. The story begins when Frisk falls into the Underground.
If you have any questions, feel free to ask! ^v^
P.S. Frisk CANNOT reset in this au -__-
