Undertale. Underfell. Underswap. Swapfell. Flowerfell. Dancetale. Storyshift. Outertale. These are just a chip off the old block for the many diverse Uundertale AUs out there. Horrortale. Mafiatale. Mobtale. Echotale. Echofell. Terrortale. Dreamtale; and so many more! We would be here forever if I tried to mention ALL of the characters in ALL of the AUs. So, I only mentioned a FEW. This is a book cataloging the many, many Sans out there. Enjoy the book! (P.S. - PLEASE comment on a AU - or ALL of them, it's up to you! You can also submit a picture/link to a new AU I haven't managed to catalog, or even submit one of your own creation!)
