The history of Error Sans begins after the events of the Aftertale. Geno, despite Sans's pleas, uses the power of Determination and accidentally sends himself into the Anti-Void. In the last few minutes, Geno was beside himself with getting his Happy Ending and hated everyone and everything except himself. After that, Geno changed in appearance and became an Errorist.

In his distraught state, Error came to the conclusion that the universes had made mistakes that needed to be destroyed, and so he sewed up his eyes, and then continued to make the universes his first victim.

In his spare time, Error watches other universes or plays with dolls in his Anti-Void. He also had a friend, DarkBlitz08, a little girl with a green soul, who turned out to be his hallucination.

The relationship between Error Sans and Geno Sans lies in the fact that Error Sans does not remember its past as Geno and considers it nothing more than another anomaly.
