His back story and I will make a info sheet on him

He was a sans with a normal universe but when the genocides started happening he couldn't handle it and snapped he killed everyone except his papyrus who was already dead because of the human. Error took advantage off this and wiped the rest of the Au from existence leaving sans alone. After spending almost years alone in the far side of the void he saw a portal into a dark place filled with timelines from not only classics time but also other universes. He named that place the timespace and soon found out who destroyed the rest of his universe he set out to find error using the timelines to go places. He would kill anyone to get to error... And he did. After a while this caught inks attention and tried to talk him into more peaceful ways but time didn't listen. He was angry that INK didn't understand his situation and attempted to murder ink as well. He failed. But he didn't know that error had already disapeared. Ink didn't give up on him. The more ink tried to help the angrier time got. By know time looked completely different than he did before. Pretty soon time was fed up with ink and would kill randomly just to tick him off. But on their last battle ink somehow locked him in the timespace. No one could get in or out. He was locked in there for many many years until classic somehow found his way in. At first time was confused at how he got in and tried to help then he realized that he could escape and complete some unfinished business with ink.....
