Sans

[Sans]

Character History:

Pre-Omniverse

Sans was among the many Monsters that lived within the Underground, trapped forever by a magical barrier constructed by Humans to prevent another war from being created. Unlike many other Monsters, however, Sans had come to accept the fact that he would never escape, and decided to make the most of it. He and his brother Papyrus eventually helped colonizing Snowdin Forest, and became citizens of Snowdin soon afterwards.

It was around this time that the first of eight humans would fall into the ruins from Mount Ebott. He never learned his name, but what he did know was that, for the first time since they got there, the kingdom of the Underground had hope. What happened was that this human was rescued by a fellow monster named Asriel, who became best friends. The human was treated just as respectfully as Asriel was, and an era of peace was at hand.

Then, the human and Asriel died.

Sans was there to witness the sudden declaration of war against humanity; all humans that fell down the hole in Mount Ebott were to be killed. He was around when he queen suddenly disappeared without a trace to be found. And he was there to see Papyrus become really obsessed with joining the Royal Guard, which he didn't actually dislike as much as he thought he would.

Six more humans fell down the hole, and they all ended the same way. During these rather terrible events, Sans had become a sentry for the town of Snowdin, with Papyrus convincing him to do so. However, he rarely did his job, much to the annoyance of Papyrus, and he instead passed the time practicing knock knock jokes at the gate of the ruins, which was the place the Monsters first entered when they went underground.

One day, however, while Sans was practicing knock knock jokes, he thought he heard a women's voice behind the door of the gate, something he hadn't heard before. To test, he did a knock knock joke that ended with a really bad pun, which then resulted in a very long exchange of awful puns and jokes between the two. For a long time, they exchanged jokes and were good friends.

Then one day, the women was doing something strange: she wasn't laughing no matter what jokes Sans used. Going quiet, the women asked him to make a promise: that any human that walked through the gate would be protected by him. Sans would later look back on this moment, saying "i couldn't say no to someone who enjoyed bad jokes as much as me."

A while later, he did just that. The eighth and final human walked through the gate. His name was Frisk. He kept a close eye on him throughout his journey through the Underground, and judged him in the Final Corridor when he was about to confront King Asgore. However, something strange was going on, and Sans knew it. He had sneaking suspicions that the human knew more than he was letting on. For example, when he was right behind the human when they first met, the human turned around at the exact moment he was about to ask him to turn around. It was also here did he get the feeling that the human was a lot more psychopathic, as he saw him kill Papyrus with his very eyes. These events eventually caused Sans to study up on quantum physics and enlist the help of scientist W.D Gaster, where he discovered the truth.

The human named Frisk had the ability to SAVE and RESET, which worked similar to time travel. Frisk could, at literally any time, reset the timeline so that he could start anew, with no one able to remember meeting him. This could make him do unthinkable actions just to see what would happen.

Upon discovering this, Sans knew he couldn't be a "lazy-bones." He had to do something.

Conveniently, the human was killing literally everything in his path, including Undyne and Papyrus. Sans had no choice but to interfere before the human killed Asgore, as his new knowledge of the timelines allowed him to foresee something... malevolent happen to the world if he did. Encountering the human in the Final Corridor, he proceeded to fight him with all of his might, possibly winning dozens of times, trying to get the human to RESET. However, the human eventually got a lucky hit, causing him to bleed out blood (or ketchup.) With the knowledge of what was to come shortly afterward combined with the fact everyone he ever loved or cared about was now dead, as well as his mortal wound, he succumbed to his injuries.

Then... he was reincarnated. In a new timeline. In the Omniverse.

[spoiler]Summary: Sans first arrives in the Nexus, thoroughly confused. At first, he laments over the loss of his friends and how he failed to stop the demonic thing that possessed Frisk, but eventually decides to take a nap to regain his energy and heal his wounds. After doing that, he decides to walk towards some nearby gates, thinking he had nothing else to really do. Along the way, he gets an epiphany: If the place he was in was a purgatory, then Papyrus could've also been alive. Reinvigorated, he charged towards the gate to the Tangled Green, starting his search for him there.[/spoiler]
