The Unforgettable Story #1-Underfell Mettaton One-Shot

Blood Will Spill!

(There will be no more Undertale so I will call UF Mettaton just Mettaton like I did in chapter "Oh My..."

Error Sans vowels A-4, E-3, I-1, O-0)

Mettaton could feel the universe flashing before his metal body. Everything stopped. He opened his top eye. He saw the entrance to his own universe. He flicked open his eyes. Error Sans was standing next to him. The blue strings weren't around him anymore. UF Mettaton jolted upwards. He looked at Error Sans with a cold stare. "Why did you send me back?" Mettaton's voice had no emotion in it. Error Sans responded with the same coldness Mettaton's eyes were showing,"B3c4us3 y0u w3r3 g3tt1ng t0 4tt4h3d t0 th4t un1v3rs3." Mettaton flinched back. He wasn't getting attached, at least Mettaton thought he wasn't. Error Sans continued on, "Th3 0nly r34s0n 1 put y0u 1n th4t un1v3rs3 1s b3c4us3 y0u n33d3d t0 sh0w c0nf1d3nc3." Mettaton stared at the open portal. "Fine, I'll leave. But on one condition, you leave my AU alone...forever..." Mettaton held out his top right hand to shake on it. Error Sans had a thoughtful expression on his face. He nodded. He shook Mettaton's hand. Error Sans smiled wickedly before shoving Mettaton into his universe. The portal closed behind him. Mettaton fell on his face. He got up. He was back where he first met Error Sans. He came out of the alley. Mettaton looked around. Monsters were rooming around, evil as normal. He saw Papyrus bossing around Sans. Papyrus noticed him. He kicked Sans before going over to Mettaton. "Hey, have you finished your tantrum yet?" Papyrus teased. Mettaton showed annoyance. Papyrus grabbed him by the waist. Mettaton didn't scream. Papyrus started to reach for his soul. Mettaton calmly and quickly turned around. Papyrus swung by his fast movement. Mettaton grabbed Papyrus by the scarf with his top left hand. Papyrus struggled in his grasp. Mettaton stared into Papyrus's eye sockets. Papyrus started to close his eyes. Mettaton smiled, showing sharp teeth. He whispered into Papyrus ear, "You shouldn't have tested me..." Papyrus struggled even more before there was a snap. Papyrus fell to the floor. But...beheaded.... Mettaton held Papyrus bloody head in his hands. Papyrus body was covered in blood with his scarf. The body dissolved into dust, leaving the scarf behind. Mettaton stared at the dust pile. He leaned down. He grabbed the scarf while also blowing on the dust pile, spreading Papyrus's ashes throughout Snowdin. Mettaton stared at the surprised expression on Papyrus head. Mettaton put his top left hand on the surface of the head. He started to push down. The head cracked. Dust was now in Mettaton's hands. He threw the dust in the air. All the monsters in Snowdin watched in complete frozen terror. Sans stared at the flecks of dust everywhere. A red tear started to fall from his eye sockets. He quickly wiped it away before going inside his house. Mettaton locked eye contact with everyone. Dust and blood was spattered all over Mettaton. Mettaton held the scarf while he turned away. He walked towards Waterfall, leaving a trail of blood and dust after him.

(In Waterfall)

Mettaton walked by his cousins house. Napstablook was staring at him, he had a look of shock. Mettaton kept walking while ignoring his cousin.

(In Hotland)

Mettaton reached Hotland. He prowled into Alphy's lab. Alphys was there, waiting for him. She screamed, "W-where were you!? I n-needed you here for t-testing! You w-were supposed to..." Alphys stopped scolding. She saw all the dust and blood on Mettaton. She had a pleased look crawl onto her face. "So,  y-you finally u-used the features I-I gave you? I'm interested o-on who y-you killed?" Mettaton pulled out the scarf. He dropped the bloody and ashy fabric on the floor. Alphy's smile turned to a look of horror. She bent down and took the scarf. She stood there, completely shocked. She looked up at Mettaton. His eyes were locked into Alphys eyes behind the glasses. He had a stoned look on his face. He leaned forward. Alphys shrunk back in terror. Mettaton smiled, showing his teeth. "Now look at this..." He purred. He tapped around Alphys. "We seem, a little, scared..." Alphys hastily shook her head no. Mettaton grabbed her by the throat with his top right hand. She didn't try to stop him. Mettaton glared at her while saying, "...give me a reason why I shouldn't kill you..." Alphys smiled, blood starting to form at the end of her mouth from the lack of air. "Because...I made you the monster you are now..." Mettaton dropped Alphys. She fell to the floor. Mettaton stared pitifully at her. He walked out of the Lab. He put his head down. Monsters watched him with fear. He heard some monsters say that his battle with Papyrus was video taped and showed on TV. Mettaton lifted his head slowly. He stared at the crowd. He said in a low, harsh whisper, "...blood will spill..!"
