Aftertale sans (otherwise known as Geno) is an OC created by LoverofPiggies (Better known as CrayonQueen). Geno is a Sans from a Genocide Route timeline who injected himself with determination from Alphys' True Lab in an attempt to control the timeline, instead getting stuck at the Save screen along side Frisk. He is now able to restore memories of people who forgot due to resets, which he uses often on Sans. He is a main supporting role in the Aftertale comic, which is now completed.
