He keeps 'puppets' of his other alternate versions of selves that he talks to calling the standard Sans, called 'Sans Classic' and naming the others by numbers. He has been stated to be a complete mystery due to his erratic and unpredictable behaviors he has.

His character is the one of confusion and somewhat hypocritical behavior since he himself is an anomaly, but sees himself as the cleanser of timelines instead. He is determined to find all anomalies and 'glitches' within various timelines and destroy them.

He is the result of an alternate Genocide Sans playing with his DETERMINATION and sending himself to the Anti-Void, where he turned into Error.Įrror is somewhat demented and psychotic. Then, he proceeds to go on a killing spree.Įrror was a glitched skeleton that was created in the Anti-Void. How he does it is that he first keeps Frisk and Flowey under guard, so they are unable to reset (he imprisons them). He likes to seek and destroy AU's left and right, except for the ones he likes such as Outertale and UnderNovela. Ironically, he does not view himself as an 'anomaly'. Now, he considers his life's mission to destroy anomalies, 'Glitches' and AUs, seeing them as 'mistakes'. He quickly began to grow insane, the emptiness and the loneliness eating up at his sanity and his anger towards everything (and everyone he had helped) shaped him into who he is now, his memory was erased during the process as well. Finally, Geno had accidentally sent himself to an empty and endless place where time was non-existent. Yet during his time in the surface, he had began to play around with his DETERMINATION, despite Sans telling him to stop doing so. He was finally free from the Save-Screen, and he finally had gotten the ending he deserved.
