Undertale 2: The Dark Future

(Back story and or info)
So the comic and scenario is 5 years after what occurred in Undertale and all the monsters have started to finally fit in and make friends with the human. Everyone was happy. Even the humans. But there has to be some person or a group of people who hate monsters. There is. His name was Perry MacDeven. He was one of the men that trapped the monsters In the Underground and he never got over the fact that they broke the barrier so he had an idea. He started to develop a gene that would take over the monsters soul and then slowly start to take control of the monsters body, slowly eating away the monsters thoughts and feelings. It would make the monster empty and almost lifeless. It would make the monster betray the ones they befriended or... loved.
