Chapter 5

Brutality

"Mettaton, take this, and go to the Core. With this human soul, you should be strong enough to stop Sans. And when you defeat him, bring him here; alive. I want that fucker to pay for what he did to Alphys." Undyne spoke coldly, as if she had no regard for anything but revenge. Mettaton took the soul and absorbed it. Upon absorbing the soul, his body instantly changed forms; from Mettaton EX to Mettaton NEO. His body now had a pink aura around it.

"This power… is incredible! Darling, that pile of bones won't stand a chance against me now!" Mettaton exclaimed, feeling as cocky as ever. He lifted his feet from the ground, realizing he now had the ability to float. He quickly soared out of Asgore's castle, and made his way to the Core, ready for his fight with Sans.

Sans reached MTT resort. Before going in, he went to the right side of the building, where there were two monsters who would normally sell things to anyone thatshowed up. They weren't there, as he expected. He looked around, but didn't find anything. Figures, they must have taken everything and ran as soon as they heard that there was some maniac going around and killing everyone. He chuckled, and went inside of MTT resort. Everyone was gone, except for one person, sitting their where normal people would buy things from him.

"One Glamburger." Sans said, waiting for the man to turn around to give him his food. As he turned around, Sans summoned a Gaster Blaster. Once he turned back to face Sans, his face scrunched up with horror. Sans took the burger out of his hands and fired the blaster, disintegrating him instantly. Sans continued on to the Core, eating his Glamburger along the way. As he entered the Core, he was confronted by small Mettaton shaped robots. They charged at him one by one, but Sans simply smacked them out of the air and on to the ground; where they exploded on impact. He knew Mettaton had to be near. He would be a good warm up for his showdown with Undyne, which was destined to happen sooner or later. He walked into the elevator and went towards the top of the Core. Once he got there, he exited the elevator to find another swarm of little Mettatons. He summoned a Gaster Blaster and fired it, not willing to take the time to swat them all to the ground one by one. Once they were all dead, he went into the final room of the Core. He walked towards the center of the room, to be greeted by smoke arising from the ground.

"Ohhhhh yes. I've been waiting for you, Sans." Mettaton came into the center of the room, looking more powerful than ever.

"Mettaton. Heh, I must say, you look a lot different." You finally start eating right? Or are you still stuffing your face with Glamburgers?" Sans chuckled at his jokes, which seemed to piss Mettaton off a little.

"Laugh while you still can, darling. You should know that there's no way you could possibly win a fight against me." Mettaton smirked, staring into Sans's blight blue eyes.

"Heh... I'm curious, what's gotten you so cocky? I mean, I know you're normally full of yourself, but now you're acting even worse than Papyrus." Sans smirked, unshook by Mettaton's confidence.

"I've absorbed a human soul, darling. With this, I'm exponentially more powerful than you!" Mettaton laughed, as he started to charge a beam in his hands. "But enough talking, we both know how this is destined to go down, don't we?" Mettaton lifted his hands and aimed at Sans. "So let's speed it up!"

Instantly, Mettaton shot a pink laser directly at Sans. Sans summoned a line of bones, defending him from the beam. Once the beam was gone, Sans shot all of the bones at Mettaton. Having nowhere to go, Mettaton flew up into the sky, letting the bones fly past him and crash into the wall. He summoned more mini Mettaton-shaped robots and sent them in Sans's direction. Sans jumped up and summoned a Gaster Blasted under him. He landed on it and rode it towards Mettaton. As he was flying towards him, he summoned a bone in his hands and smashed all of the robots flying towards him. Once he got close to Mettaton, he fired his blaster and teleported off of it. Mettaton shot his own laser at the beam, pushing it back into the blaster. However, Sans appeared behind him and smashed the bone in his hands against the back of his head. The impact of the hit made Mettaton shake, weakening his laser. Unable to combat Sans's blaster with the damage he took, he descended to the ground to avoid the blast. He looked up, and saw that Sans was missing.

"What's wrong? Afraid of dying?!" Mettaton smirked, but it wasn't a confident smirk, more so a nervous smirk. Suddenly, a bone was shoved through Mettaton's back, piercing his torso entirely.

"Death? No, it wouldn't make sense to be afraid of the gift I give to fuckers like you." Mettaton looked up, seeing Sans with a storm of bones behind him. Sans teleported away, as all the bones started to fall down at Mettaton. Mettaton gripped the bone in his chest and ripped it out; grunting in pain as it came out, leaving a massive hole in him. Mettaton looked up at the bones that were falling right in his direction. He raised his arm to cover his face, but the bones still pelted him. He staggered as he tried to walk, now that he's taken so much damage. Now that Mettaton was weakened, Sans used his blue magic and lifted Mettaton off of the ground. "This is the longest fight I've had so far. I have to say, I'm almost impressed." Sans snickered as he summoned a Gaster Blaster and pointed it at Mettaton.

"D-Don't think this is over yet!" Mettaton grunted, still sounding confident as ever. "I'm not done… not yet!" Suddenly, white, blue and orange lasers came from Mettaton's chest. Sans dodged the white lasers, let the blue lasers pass through him, and charged through the orange ones. However, in the midst of going through an orange laser, he bumped into a white laser, knocking him down and releasing his grip on Mettaton.

"Y-You… You just… n-ngh…" Sans's vision blurred. Sans was never able to take hits very well. In his blurred vision, he saw Mettaton walking towards him, looking cocky as ever. Sans closed his eyes, feeling like he was dead… but suddenly, something burned inside of him. There was now a distorted voice in Sans's head, that spoke no words; except for "KILL". He felt a surge of power, unlike anything he had ever experienced. He opened his eyes, and a bright blue light emerged from them. He floated off of the floor and stared Mettaton in the eyes. Mettaton looked at him, with a scared expression. Sans made a fist and shoved it through Mettaton's chest, ripping out a pink heart.

"Th… that's…!" Sans chuckled at Mettaton's fear, as he held the pink soul in his hands. Without any hesitation, Sans absorbed the soul. As he absorbed it, a ball of light formed around him. The ball of light expanded and faded, and spread smoke across the battlefield. From the puff of smoke, came out Sans. His physical appearance hadn't changed much, but now he had a blue aura surrounding him. His wounds were also healed completely.

"Did you REALLY think you could kill me that easily? No, I won't die that easily. NOTHING can kill me, you insufferable piece of scrap metal. I am immortal to lackeys like you and Undyne. I am a fucking GOD compared to monsters like you and Undyne." Sans once again used his blue magic, and threw Mettaton across the room. He summoned bones, and shoved them through his metallic limbs. As Mettaton screamed in pain, he shoved blue bones through his head. With the bones penetrating him, Sans snapped his fingers and summoned a bone in his hands. "Heh heh heh… I was going to give you a quick death, but you've REALLY pushed me here." Sans put the bone in his hands to Mettaton's shoulder and sharpened the ends of it. With the bone that was now as sharp as a knife, he slashed at Mettaton's body, cutting off one limb at a time. Mettaton screamed in pain with every slash. "Ha! AHA! AHAHAHAHA!" Sans laughed like a maniac as he ripped through Mettaton, cutting him up further and further. He continued doing this on and on, until Mettaton wasn't recognizable anymore. He became nothing but broken pieces of metal. His eyes were now empty and all lights on him had faded. Mettaton was dead. Sans stopped slashing away at him, and looked at his 'masterpiece'. He decided to leave Mettaton there; or rather, whatever was left of him.

Sans now had two human souls absorbed. There were only 5 more souls. If Mettaton had one, then Undyne and Asgore must have had the rest. Sans had more intense battles coming.

And he was more ready than ever to kill.
