Description: Error404 Sans, native to the alternate universe "AlphaTale". !!WALL OF TEXT WARNING!! Backstory, from the AlphaTale Wiki: Error404 used to work together with his brother, Alpha Sans in their AU "Undertale 2.0". In their AU, there were only two Sanses, as they did not have a Papyrus. They both wore jackets with numbers on their back so that the others could tell them apart. Alpha had a number 1 on him, and Error404 had a number 2. Every day they helped those who needed help within their world. But, out of the ordinary, an unidentified Sans entered their world and started killing many of the inhabitants. He was known as Mix!Sans, but was more well known as Infected. He showed up in search for more LV (Level of Violence). Infected waged a terrible battle in which Error404 and Alpha had to stop him. They fought and fought until eventually, they came to an impasse. They got their breath back and before they could react, Infected killed Alpha!Sans. Error404 mourned over his brother's death while looking at his dust. Infected smiled with pride and glee. Error404, boiling with rage and sadness, tore open a rift in reality with his bare hands but was immediately killed by Infected before he could do anything. Error404 lied on the ground looking at his brother's dust and then made a mistake that would haunt him until the end of his days. He decided to teleport him and Infected into the Anti-Void, a place that was uninhabitable at the time. They both had arrived and Error404 immediately starting hacking the Anti-Void. This occurrence drove him insane in just a fraction of a second. Then once he stopped, he attempted to tear his face apart, causing him to appear like he was crying this black ooze. He then grabbed some of the Anti-Void code and used it as wires to delete Infected. This was possible only because he hacked the Anti-Void. It gave him everlasting life and incredible durability. This gave Error404 just the right amount of power he needed to kill Infected. alphatale.wikia.com/wiki/Error404!Sans
