ERROR

Error! Sans is an alternate universe (AU) character created by LoverofPiggies (CrayonQueen), known as a "Multiversal Destroyer" who travels the multiverse to destroy all Alternate Universes (AUs) he considers anomalies or flaws. He uses "Gaster Blasters" and ropes to manipulate and bind his victims, and originates from a genocidal timeline where he suffered irreparable "errors."

Origin

Error! Sans was originally a version of Geno from Aftertale, who became an irreparable glitch after messing with the determination in his timeline.

He fell into a dimension called "Antivoid" and became the destructive version we know, believing that AUs are failures that need to be eliminated.

Appearance and Skills

His appearance is similar to Sans, but with a "buggy" design, different colors and visual glitches.

He uses threads to bind and control others, as well as travel through the multiverse.

Other abilities include shooting Gaster Blasters, controlling the victim with his strings, and the ability to teleport between universes.

Personality and Motivations

In the present, Error is a flawed black skeleton, with a color palette primarily consisting of reds/dark reds, blues/dark blues, yellows, oranges, and blacks. His entire torso is black, while his legs are red. His metacarpals are black, while his proximal phalanges are red, and his middle and distal phalanges are yellow. He has yellow teeth and two asymmetrical eyes, with completely red sclerae, one with a small yellow pupil and the other with a yellow, blue, and black circle. He usually has to wear round red glasses because his eyes are messed up from his time as Geno, but he sometimes refuses to wear them. His most striking feature is the light blue teardrop-shaped markings that run from his eyes to his chin.

Personality

He always seems grumpy, but he has a selfish and somewhat playful personality and thinks he's helping the multiverse. He steals things, invades and destroys AUs, and loves to make jokes and sarcastic taunts with his enemies. Canonically, he doesn't get angry until things don't go his way, as he expected, or when others trigger one of his fears. And while he has a lot of hatred for non-canonical material regarding Undertale, those that deviate even slightly from the original irritate him the most [3]. This makes him, as the creator put it best, a literal man-baby [4].
