Personality
Silent, he prefers to reveal his true intentions first, no longer having any particular reason to hide them. A master manipulator, he's evolved to the point of perfecting a poker face. At first glance, Error404 appears to be a sociopathic experimenter, working in the background to deal with whatever he perceives as a problem. At the slightest insult, he'll take the most exaggerated response. A permanent solution to a temporary problem.

However, this isn't really Error404. Error404 retains his sadness, but instead usually transforms it into sternness, which is often the cause of his intimidating stance. Despite his reputation as a formal sociopath, in person he comes across as a pure beast, always dominating the situation whenever he's present, always knowing the right thing to say, and always coming out on top. Error404 has a complete god complex, but he's truly not a bad person.
Story
Error 404 used to work alongside Alphatale!Sans in their AU, Undertale 2.0. There were two Sanses in their universe, since Papyrus was missing. They both wore numbered jackets so others could tell them apart: Alphatale!Sans wore number 1, and Error404 wore number 2. Every day, they helped those in need. But one day, Infected!Sans entered their world and began killing. He came seeking more LV. Error 404 and Alphatale!Sans had to stop him. They fought until they eventually reached a dead end. They ran out of breath, and before they could react, Infected!Sans killed Alphatale!Sans.

Error404 mourned his brother's death, looking at his ashes. He, seething with rage and sadness
