Chapter 3
Power
Undyne took Papyrus home. Papyrus cried the entire way, but Undyne couldn't help him, even though she tried her hardest. She couldn't really blame him, after the way Sans acted. Papyrus went into his house and locked the door behind him. He needed time alone, and Undyne needed time without Papyrus by her side. As much as she liked Papyrus's company, what she was about to do would be impossible if Papyrus was around. She went to the river person, and road to Hotland. As much as she hated it there, she was able to get through without her armor. Once she got there, she headed straight towards Alphys's lab. On the way there, she saw the Royal Guards standing their post. She'd wondered to herself what they would do once they were free. Asgore was always shaky on the subject of killing all the humans on the surface world. Asgore only wanted to do violent things when they were necessary, and if they weren't necessary, then he would never even think of it. How weak, compared to Undyne. If Undyne was the ruler of the monsters, she would be more than willing to kill all of the humans on the surface world. But, that was just a fantasy to her, as she was only the head of the Royal Guard. Though, if something were ever to happen to Asgore, she could take over as the Underground's ruler. But she was honorable; she would never try to do something to Asgore.
Within a few moments, she had made it to Alphys's lab. As she walked towards the door, it automatically opened. "Alphys! I need to talk to you!" Undyne called out, Alphys was in the room, just coming down from the conveyer.
"O-Oh, Undyne?" Alphys was surprised to see Undyne there; normally they would meet in Waterfall. She realized how important it must've been if she was coming here.
"Alphys, look… Sans has lost it. We need to talk to Asgore, as soon as possible."
"W-What do you mean he's lost it?" Alphys knew Sans from a while ago, there was no way he'd no anything crazy.
"A human came to Snowdin forest, and Sans killed them. Papyrus told me, and we went to go take the soul. But when we got there, Sans was already there. He absorbed the soul, and threatened to kill me! I don't know what's going on in his head, but I can assure you that something is REALLY wrong with him. We need to stop him!" Alphys took a step back, this is unlike anything Sans would ever do. Sans had a reason for everything he did. If he ever actually did something, he must have had a really good reason. But still… she couldn't just dismiss what Undyne said.
"A-Alright… we'll go to Asgore then. He'll know how to handle this."
"CAN I COME WITH YOU?" Undyne and Alphys flinched, then turned around to see Papyrus standing there. Did he really follow Undyne there?
"Papyrus… I thought you locked yourself in your house?" Undyne asked, as she looked into Papyrus's eyes and saw his sadness. But behind his sadness, she could sense a burning determination.
"I DIDN'T STAY THERE FOR LONG. I WANTED TO, BUT I COULDN'T LET MYSELF. IF YOU TWO ARE GOING TO ASGORE BECAUSE OF SOMETHING THAT HAS TO DO WITH SANS, THEN I WANT TO COME WITH YOU. NO IFS ANDS OR BUTS ABOUT IT." The sadness in Papyrus's eyes slowly started fading. It's as if he thought Undyne and Alphys wanted Sans dead. They didn't, they just wanted the soul. But… if it came down to it… they may not have much of a choice in the matter.
"Okay, Papyrus. If you really want to come with us… then fine."
"THANK YOU…" Papyrus took a sigh of relief. He was happy that he was able to go with them.
"F-Follow me, I know the way." Alphys started going towards the exit, as Undyne and Papyrus followed her. She was scared, but not as scared as Papyrus was. Deep down, Papyrus was petrified. He tried to stay strong, tried to resist his fear. To some extent, it worked. But even still, he was scared. Scared for himself, and scared for his brother.
A few hours later…
Sans found himself back at the bench, unsure of what to do now. He felt so much different now that he had absorbed the human soul. His eyes constantly glowed blue. His left eye used to glow blue whenever he would concentrate his magic, which rarely happened. However, ever since he absorbed the soul, not only did his left eye glow, but his right eye did as well. It's like he was constantly concentrating his magic. It made him… curious. He decided to teleport away from the bench and to the room with the duck that would carry along anything that wanted to be carried. The duck was small and fragile… and a sitting duck. Pun intended on Sans's part. He focused his magic, and almost instantly a Gaster Blaster spawned above the duck. It was incredible, usually they would take much more concentration to summon, and Sans would have to be experiencing emotional distress But this time, he was able to do it so easily. Suddenly, he felt something urge him to fire it; to see how strong it was. Without any hesitation, he fired his blaster. The white beam shot down and smashed against the ground, raising dust and rocks from the ground. Once the white beam was gone, he noticed that the small duck was gone too. He must have accidentally killed it. Sans felt… really weird now. He had never killed anyone before, aside from Frisk on their genocide routes. Usually, the timeline would instantly reset after he killed them, but now it didn't. And now that he's killed something… he feels stronger. It was like by killing something, he gained more offensive capabilities. Curious as ever, Sans decided to put his theory to the test. He quickly teleported to Snowdin Forest, and hid in a bush. After about a minute, Icecap started to walk by. Without any second guessed, Sans used blue magic to lift Icecap off of the ground and smashed him into a tree. As he smashed him into a tree, Icecap's body became dust; and once again, Sans felt stronger. Normally he would feel horrible for doing something like this, but now it was like he wanted to see just how strong he could potentially get.
For the next hour, Sans spent his time killing innocent pedestrians that walked through the forest. Normally he would feel absolutely horrible for this, but now he couldn't help but laugh after every kill. He must have killed a hundred monsters. Eventually, monsters stopped showing up. It's as if everyone evacuated the area. He went to town, to find that it was completely empty. It was like everyone heard that someone was killing monsters in the forest, and they all ran away and hid somewhere. But… he felt no guilt. He felt stronger than ever before.
He walked out of Snowdin and into Waterfall. He decided that Waterfall was far too crowded.
He decided that he'd show the monsters of the Underground that he wasn't just some lazy pile of bones.
