Error 404

The Long Jacket (Error Jacket) Base Color: It is a long jacket or coat in dark blue or navy blue. The Printed Number: The most important detail from his past in Alphatale is that he has the number 1 printed somewhere on the jacket (his brother, Alpha!Sans, wore the number 2). Pixel Pattern: The bottom hem, cuffs, and inner edges have a pixelated pattern or stripes of bright blue (cyan) and white, simulating a loading error or computer glitch. Collar Fur: Unlike classic Sans who wears gray or white fur, Error404's hood fur is usually pure white or bright cyan. 👕 Undershirt/Sweater Color: Under the jacket, he wears a plain, deep black undershirt or sweater. Contrast: It serves to highlight the white ribs and blue threads sprouting from his body. 🩳 Shorts Base Color: He wears black athletic shorts. Side Stripes: They have the Iconic vertical stripes on the sides, but in his case they are cyan or white. 🧦 Footwear and Legs Slippers: He wears slippers that are usually cyan or black with blue details. Socks: In some official illustrations, he wears white socks or pixelated textures on his legs that resemble corrupted code. 🧵 Threads and Tears (Visual Accessories) Puppet Strings: Cyan threads constantly fall from his eyes and fingers, which he uses to control the souls and codes of other Sanses. Scarf (Optional depending on the transformation): In some of his advanced forms (such as Butterfly or God form), he incorporates additional elements such as a tattered blue or white scarf.

Cruel and Manipulative: He lacks empathy for most anomalies. He uses his mind manipulation abilities to bend other people's souls and force other monsters to serve him. A tragic backstory: Behind his evil and chaotic facade, his hidden motivation remains to recover the code of his lost home and revive his dead brother.

Cold and Calculating: He works methodically from the shadows. He doesn't act on blind impulses, but rather through structured, long-term plans to control the multiverse. Madness and Dementia: His mind was completely fractured after witnessing the death of his brother, Alpha!Sans, and the destruction of his original world. He suffers from severe hallucinations and constant delusions. God Complex: He sees himself as the rightful puppeteer and protector of the multiverse. This leads him to manipulate other powerful beings, even going so far as to "create" King Multiverse to use as a pawn.

She is the teacher and indirect "mother" of the well-known Error!Sans, whom she manipulates from the shadows to achieve her own goals. Her main objective is to gather the fragments of her destroyed universe to rebuild Alphatale, no matter how many worlds she must erase in the process.

Abilities and Powers: Code Manipulation: Can edit the code of AUs, revive the dead, and erase other beings from existence. Mind Control: Uses dark blue threads that allow him to control the souls and minds of others as if they were puppets. Omnipresence: His senses are limitless; he can turn invisible, detect any lie, and see temporal anomalies. Immortality: Possesses an infinite lifespan and absolute regeneration.
