Author's Note: And yes, I just released the chapter early. :D
Papyrus's POV
It was a rainy day in Snowdin. Papyrus, who is now carrying Sans' blue jacket, was carrying a jar of dust in his hands, sprinting into Waterfall. Monster Kid noticed Papyrus, so he decided to go after him, to see what's wrong. When Papyrus finally got in the Waterfall, he noticed something... Undyne was dead. She now was a pile of dust. Papyrus cried once more and decided to check. "UNDYNE!" Papyrus screamed in tears. "No no no no no!" yelled Papyrus. "Why my loving ones are dieing today!?" Monster Kid decided to calm down Papyrus. "...Papyrus?" After Papyrus was done sniffing... "Wait a minute... Monster Kid?" Said Papyrus surprised that Monster Kid was here. "Why are you here?" asked Papyrus. "I seen you carrying a jar, and wearing Sans' jacket, so i decided to check out what's happening." Papyrus started sniffing again. "What's wrong, Papyrus?" asked Monster Kid. "THAT JAR IS SANS!" He started crying again. "Don't worry, everything will be OK." Monster Kid said comforting Papyrus. "Really?" Papyrus said. "Yup. Even with Undyne gone, it will be OK." Papyrus stopped crying. "Alright. We will get to Alphys, and we will see who killed Sans. If i will find the killer, I will kill him. If he will escape, Then I, The Great Papyrus, will have no choice but to find the killer again and THEN KILL HIM." battlecryed Papyrus when his left eye turned suddenly orange. "Well then, Let's go to Alphys!" said Papyrus pointing his finger at the mysterious river person. Papyrus and Monster Kid got near the river person. "Tralalalala... Today is pretty rainy, don't you think?" Said the river person. "Yes, it is indeed pretty rainy." answered Papyrus. "Anyway, where do you want to go?" Questioned them the river person. "HOTLAND!" Papyrus and Monster Kid said in chorus. "It is Hotland, then." answered the river person. Papyrus, Monster Kid and the river person go to Hotland. "Well then, I will be returning to Waterfall now. Goodbye!" Said the river person leaving to Waterfall. "Bye, mysterious person!" said Papyrus & Monster Kid in chorus. Papyrus and Monster Kid then walked up to Alphys' Lab, when suddenly... "PAPYRUS, MONSTER KID! I AM GL-GLAD YOU ARE H-HERE! GO CHECK IT OUT!" Papyrus, Alphys & Monster Kid walked up to the monitors. "An human killed Sans & Undyne!" Papyrus gasped when he heard those words. AN HUMAN KILLED SANS & UNDYNE. The only words he actually cared about for now. "I KNEW that the killer was the human all the time!" Papyrus said clenching his fist. "When i see him, I will KILL HIM!" Papyrus raged. "Anyway P-Papyrus... What's t-that jar you're holding?" Alphys gave Papyrus a question that he easily answered. "This, Alphys, is supposedly what is left of Sans." Answered Papyrus. "Oh. Great! He will be my test subject for the Un-Dust-Izer!" Alphys said who looks to be surprised. "...and t-the second jar?" asked Alphys. "Undyne." answered Papyrus. "Well then... Let's test out the Un-Dust-Izer (working on the name...)." answered Alphys. Alphys opened the jar of Sans's dust and placed it in the Un-Dust-Izer's pod, along with Undyne in the second pod. "Will it work?" said Monster Kid who seemed to have a suspicious look at the machine. "There are two possibilities, Either it will work or Either it won't work just like my "Injecting Determination" experiment." answered Alphys. "Well then here it goes!" Alphys said pulling the lever. The machine started working. Sans & Undyne were slowly being revived. But... Something went wrong. Both started melting, just like in the experiment. "W-What the!?" Alphys yelled. Alphys was terrified as her crush, Undyne, along with Sans were turning into monsters. "Papyrus, Monster Kid, come here!" Alphys nervously yelled to Papyrus and Monster Kid. Both of them were worrying about Sans & Undyne, So they quickly ran into the lab. When they were there, it was too late... Sans & Undyne had turned into Amalgamates, Sans's bones seems to be melted and has 1 blue glowing left eye, While Undyne's shirt, pants, shoes, body & eyepatch seemed to be melted. They were like... "Monsters Of Justice Made Out Of Megalomaniacs".
Frisk's POV
"Why are you controlling my body, Chara?" Frisk asks as she is chained to some mysterious wall. "BECAUSE, Frisk..." Chara started as she killed every single Temmie in Temmie Village. "It started a long ago, when Monsters were in the Underground, and where the outside is blocked by the Barrier." The screen flashes to a flashback.
But wait! What's this? A cliffhanger!? But some mysteries are still unsolved? Why Chara Possessed Frisk's Body? What Dark Secret Chara Has? How Will Papyrus, Monster Kid & Alphys (Mettaton too) defend themselves against the "Monsters Of Justice Made Out Of Megalomaniacs"!? Find out in the next chapter!
Either way about the whole "Monsters Of Justice Made Out Of Megalomaniacs" thing... This annoucement may clear it a bit more.
MOJMOOM - Sequel To Disundertale. A story focusing on Sans & Undyne, which are still amalgamates after the whole story (Oops, spoilers).
