Error Sans

He was an ordinary Sans.
He once lived in his classic Undertale world (with Papyrus, Sansa, and Frisk). He was just a lazy skeleton who joked about bones and ate hot dogs. His world was destroyed.
His universe was invaded by Ink!Sans (before they became enemies). Ink, who couldn't yet control his powers, accidentally erased Error's original world while trying to save it from another threat. He fell into the Anti-Void.
Error didn't die—he was thrown into the void between worlds, where there is no time, no sound, no life. He was left completely alone, with the realization that his brother, his friends, and his home were just a "deleted file." He "broke."
Years of loneliness in the void, without food, sleep, or communication, had destroyed his mind. His body cracked, and his soul shattered—he became a "glitch." To avoid going completely mad, he created a new goal: to destroy other worlds, because "if my world doesn't exist, why should others exist?" He lost Papyrus—his greatest pain. In some cases, he hallucinates his brother or hears his voice in the void, as well as himself—he barely remembers what he was like "before." He becomes angry at anyone who tries to remind him of the past.

Personality: Sarcastic, impulsive, and quick-tempered. He can laugh at someone else's death, but then immediately fall into a quiet depression. A sociophobe with haptophobia, he prefers to observe the world from afar rather than be inside.
He is 23 years old. He controls blue threads that flow from his eyes and fingers. He is a nihilist and sociophobe. He hates both himself and others. His main enemy is Ink.

Error simply hates glitches, broken AUs, and things like that. He also hates Fresh and Ink, but he treats Blueberry better than the others. His favorite is Classic. He also dislikes loud noises, loss of control, questions about the past, and a little bit his own reflection. In fact, he has slightly low self-esteem.

Error enjoys destroying incorrect worlds and errors; in his opinion, he cleanses the world of glitches. He loves to provoke and swear, and he has a rather sarcastic and caustic personality. His weakness is chocolate. But even such a person has a hobby: knitting. He also actually loves cute things like stuffed animals, but he tries desperately to hide it.
