Don't ask where I got the idea... I just learned about Error Sans and I've always loved Aftertale Sans. I instantly fall in love with every Undertale AU, even UnderFell. Most art of it is just creepy. I'll do more Sans au ships if wanted. For example; Sans x Underfell Sans Swaptale Sans x Sans Error Sans x Underfell Sans Error Sans x Swaptale Sans Sans x Aftertale Sans Gaster Sans x Sans Aftertale Sans x Underfell Sans Gaster Sans x Underfell Sans Gaster Sans x Error Sans

Error!Sans is an opposite of Aftertale. He can control your soul and make you his puppet. How does he do that? He has magical strings that he can tie around your soul. He believes that there should only be ONE timeline, and all the other timelines are just ACCIDENTS.
