When an experiment causes a radiation leak, twins Dipper and Mabel Pines find themselves mutating into monsters beyond what they ever thought possible. But as they barricade the town to stop tourists from finding them, government forces close in and time is running out for Dipper, who is captured for experimentation....oh, and one more thing...watch the mirrors...

Because I literally cannot seem to hold onto anything right now and I'm going insane from obsession. it's bad guys. So when Mabel, Dipper, Grunkle Stan, and Bill get transformed into monster (except for Bill, everybody loves Bill) they have to sustain normal life at the shack, and keep their secrete. With Stan sleeping during the day it's been hard, but when mythical hunter catch whiff of their cover up, things get from bad to worse. bum bum bum

Hi again everyone! ^.^ I hope you all enjoy my BillDip/Bipper fanfic! I want to let you know, that this WILL contain a lot of lemon, maybe language, maybe violence (or blood), and not too much fluff, tho. I want to make it interesting, and have more of a story to it. (Also, my writing style does change a bit as the story progresses, I don't know if you can tell or not...but, whatever. I'm not the most amazing writer, soooo..) (And btw, Dipper is sixteen years old.) Thank you! Enjoy!!

[Adopted by @Ghosty-and-Cloud, @dreamdemonlord, and @kelala_wizner] Weirdmageddon is ending and everyone in Gravity Falls is there to witness. All the Interdimensional criminals and nightmares that Bill called his friends are being sucked back inside the rip. But Dipper's decision changes Bill's fate. "PineTree... Let me do this... Please." Dipper remained silent for a moment. "Alright Bill." [Billdip] I do not own Gravity Fall people! But I'm a major Fan ^^

Bill wanted someone to care for and share his knowledge with, just between the two of them. But Bill never wanted a lover, being a demon was an advantage because they were a mix of both genders. Then when it's almost time for the baby to come, Stanford enters and banishes Bill into a deep place into the mindscape. After the banishment the container hatches and a baby boy is born, so Stanford gives the demon child to his relatives to care for along with their new born baby girl to be raised human. Dipper and Mable's first summer is almost about to end, but Dipper shines some black light over Bill's page and finds out he has a son. With the emotions of betrayal and distrust lingering on him how will he handle what's to come. Now that Bill's back he wants his Son no matter what! And Bill has a way of knowing where he is. Join them for a life of fun and conflict! Disclaimer: I DO NOT OWN GRAVITY FALLS!!!
