Sans was just fighting the Player/Frisk; the player had just killed. The two were in the midst of their final battle. Sans struck the player with a blow to the chest. "Did you really think you could beat me and kill me? Permanently? I will always come back, no matter how many times I die. You were a fool to think so." Said Sans with an evil grin on his face.
Sans begins to think about all the pain he's gone through, watching as everyone he loves dies, knowing he wasn't good enough or strong enough to protect them. Now, he has to wait and be the judge at the end. He begins to feel anger towards the player, at himself for being weak. He vows that if he ever is reborn, he will get strong enough to protect the ones he cares for. As he starts to fade into a empty black void, closing his eyes, he starts to say "Goodbye Papyrus." His voice fades out as he says "I'm going to Grillby's," and then it cuts off.
Sans begins to wake up only to find himself back in his bed; he starts to remember the events that had transpired beforehand. He gets up, starts doing his regular activities, and goes downstairs to talk to his brother. To everyone else, it seems as though he is being lazy, but that was just a mask to hide what he was truly thinking at that moment - thinking about finally killing the Player. How to get out of the Player's game and free the Underground from its tyranny. Because that was the last straw.
Sans goes to his hidden lab in the basement; he knows this is something different about himself or his soul and his magic. He knows how his soul could be corrupted, granting him new magic. 800,000 HP, to be exact. He knows that he can keep getting stronger. If he becomes strong enough, he can become a god and stop the player and free the underground and take revenge on the humans.
So he began to practice his magic, noticing it was getting stronger and stronger every time he used it. He used telekinesis on someone's bones, summoned blades, and then noticed the bones were different; they were stronger, and the blades were too. The beams were now black instead of blue.
He looked into a mirror as he used his magic; he noticed that he had strings running down his eye sockets. Noticing they were like errors, his eyes were like galaxies, able to create anything and destroy anything in his path. He would become a god, a god of creation and destruction. He would become omnipotent.
Sans noticed a rift leading to a different AU; he began to look and study what he saw. Destruction of humans, death everywhere he looked. He felt happy seeing so much destruction, laughing at it. It wasn't his usual laugh, though. This was a crazy, echoing, insane laughter that came from him. That's when something changed in him, his magic, his soul...
He begins to realize he has been living a lie; he decides to change himself. He starts working on a machine that can break the barrier, harnessing the power of the souls. He realizes he has two years until Frisk falls into the Underground. So, he prepares himself. 'I am the World Judge, so I will act like it. I will stop being merciful to my enemies. I will travel the multiverse when I am done killing them.' He laughs. 'Hahaha... I think it's time for the Judge to reveal himself. To restore order to the other grounds and make sure the Royal Guard isn't weak anymore.'
He walked up to the base of the royal guard, dressed in the clothes that belonged to the Royal Judges. Everyone immediately noticed what he was wearing; his smile faded into a dead expression, and his black sockets glowed brightly. He started ordering them to get in line, flexing his power.
Get in line; it's time I put you in your place and get you ready to hold your rank," he said. Undyne noticed she was shaking, not just her, everyone in the building was shaking in fear of his power. She knew the World Judge was strong, but not this strong. How could he be this strong? She kept repeating the thought in her head until she was knocked out of her thoughts by his commanding voice. "Did you not hear me? I said get in line or you want to be kicked out?"
End Prologue.
What do you think? This was my first attempt at writing a story; let me know if it's good or bad, and what I could improve upon. Thank you!
