Error404 used to work together with AlphaTale!Sans in their AU UnderTale 2.0. In their AU they didn't have Papyrus because they had each other. They both wore the same blue jacket, but instead so people wouldn't get confused they both had numbers on they're jackets. Error404 wore 2 and AlphaTale wore 1, and every day they worked together to help people who needed them.
But one day another a Sans entered their world and started killing people/Monsters. He was known as Mix!Sans, but was more well known as Infected. He came seeking more LV, 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 cried and mourned over his brother's death while looking at his ashes. 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 in which was uninhabitable at the time.
They both had arrived and Error404 immediately starting hacking The Anti-Void. This event drove him insane in just 2.9 milliseconds. Then once he stopped he began 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 has wires to kill Infected. This was possible only because since he hacked the Anti-Void, it gave him everlasting life and almost 50% invincibility. This gave Error404 just the right amount of power he needed to kill Infected and send him to Hell.
He had won the battle, but at what cost? He had become a monster unrecognizable by anyone and had gone insane. Error404 hid away in a special part of the Anti-Void that only he can access called the Main Frame/The outer wall, a place where he can see all activity in and out of the Anti-Void. He has been there ever since, never to be in contact with other AUs, slowly driving himself more and more insane.
How Error404 and Error!Sans met.
It all started 2 days ago, I was just looking for the Omega Timeline...Ever since the true between me and ink was set in motion i've been forbidden from destroying any more AUs.But of course this wont stop my progress from finding that stupid Omega TimeLine. Ink was doing his own little thing while i took care of what i was doing. As Usual i started to try to get a feel for where it might be.So i start teleporting everywhere in hopes of accidentally teleporting inside the OmegaTimeline. But instead on that particular day i found myself teleporting to the end of the multiverse.I found myself in at a cliff like area with endless black abyss at the bottom of it. I could hear the Shattering and clinks of broken glass all over the place. Error: I should the hell out of here before i end up getting caught in the moment. But before i could teleport i heard someone speak something to me.???:Well Hello there. I Froze in place and as i turned around slowely i saw a figure that seemed to similar to my appearance...this was somewhat frighting and for the first time in my life i had no idea what do. As this thing walked closer and closer towards me. it continued to talk to me. It would ask things like,what's my name?,where are we? and how long has it been?.I then decided to ask him a question. Error: Whats your Name?. The Figure stopped and said.???: i dont have a name.....Whats your name?. Error:It's Error!Sans.???:Error!Sans hu, well i hope you dont mind if i steal you name.Error:WHAT?!??NO WAY-.???:Hm what would fit well with Error.As i stared at him,he kept thinking for a way to sully my name and wasn't about to have it.Error:HEY BUDDY JUST WHO DO YOU THI-.???:I know! How about Error404. This was a very unsual thing to happen i knew right away i should destroy no way i have someone walking around with my name,so i decided to take action.Error:Thats enough your obviously trying to deceive me so i think i'll just destroy you like everything else i encounter.*Error's blue strings surrounded Error404*Error:Heh now any las-.Error404: What are these?.Error:.....These are my strings they destroy and help me destroy anything and all in my path.Error404:I think i wouldn't mind taking these,to help me complete my plan.Error:WHAT! you cant have them they're my powers and they onl-. Suddenly He glitched in front and before i knew it he had already ripped the strings that were present with me out of my hands.Error:WHAT THE!!?! YOU SCUM?!?!.Then he threw me in the air with the strings and then brought me back down full force.Error:You rat i'll make you wish you we-.And then i found myself being throw again and again and again . Eventually knew that the only way he was stopping was if i surrendered.He threw me to the ground once more,but this time i looked at him and yelled.Error:I give up.Error404:Oh really*Error404 walks over to Error!Sans and looks down at him*Error:I now know that i have no chance at wining so you win this time,but i swear when i-.*Error404 Crushes Error's Hand underneath his foot*Error:AHHHHHHHHHH!!!.Error404:Do you think im a idiot you want me to spare your life?just so you can go back and get your strength back.Nope!I think im going to make you my new partner,your going to do exactly what i say or else. *Error looked up at Error404*Error: Fine! but what could you possibly offer me that i cant gain myself.*Error404 gets his foot off of Error's hand*Error404:Knowledge Error the most powerful of all of Powers,But before i share such vital information with my new partner i must know who's side are you on?Error: I dont have a side.Error404:You don't do you....Excellent.
He acts just about the same as Error!Sans does except he lives alone and has no one to talk to so he just talks amongst himself. He hates everything except for himself. He also believes that he's flawless and doesn't have to obey even the makers rules. (Someone needs to send this guy to the island with Error and Ink). Also when he gets mad, he glitches a lot that his colors change. Also when he doesn't feel like talking normally he will speak in morse code. He doesn't mind being touched as long as it doesn't involve physical contact. He is curious about AUs and won't attack or kill anyone unless he finds them a threat to him. Error404's emotions are fairly similar to lord beerus' in Dragon Ball Super.
Error404 Sans wears a white hoodie with a hint of black at the top. He also wears a pair of white shorts with a black stripe and a black shirt. He wears white slippers that have a black bottom. His skull is completely white with black stripes going down his face. He has a nice pair of blue teeth, eyes, and fingers. Everything apart of his body is white except for his eyes, teeth, fingers, shirt, black stripe on his shorts and his legs which are black.
These strings can travel through and into AU timelines. They can control you as well if the strings are wrapped around your SOUL.
This Power makes the cables wrap around your SOUL and mind, unlike error's cables these are permanent until Error404 decides to let go or until his new puppet dies. This power will control you without you even realizing it. Example: Sans could be calmly talking to Papyrus, but in reality, he's choking him to death.
Dark blaster's total damage is 9,999,999
This will fire a blast from Error404's fingers that will pulverize anything in its way permanently meaning you wont be able to heal a scar caused by this ability.
