Gravity Falls Welcomes You (xreader)

Bill is Bad

Bill's P.O.V.

     Damn Pinetree. Always sticking his nose in business where it doesn't belong. He's messing with my new puppet. MY puppet.

      It's bad enough he ruined Weirdmaggedon. And THAT was pretty bad. I still can't figure out how the meat sacks did it. I am also still appalled that they were able to strip me of most of my powers and reduce my presence to almost nothing. I mean come on, they're a bunch of brainless, not-evolved, stupid mortals who just so happened to get lucky and catch me off guard.

      My laughter sounded manically strained as I stared into the empty, white abyss. When I chanted to the ancient powers to allow me to return I didn't mean like this. I was weak and nothing. I lost...But, there still might be some hope. My strength and powers have came back to me slowly, but gradually and I've been sitting back, waiting for revenge.

      Not take-over-the-world-revenge, though. Just on the Pines family and maybe Gravity Falls in general. I'm kind of over the whole 'world domination' thing. Well, at least at the moment. Maybe later though...Yeah, I've got a couple more ideas...

        Anyway, not the point. I've already claimed (Y/N). For some reason, I've taken a somewhat liking to her. She was so indescribably unique. She was different from other meat sacks. For example, when I showed myself in the Mindscape, she wasn't scared of me; she laughed at me. It's very strange-most people fear me, but she faced me boldly and joked around. Then again, she thought I was a Dorito's logo. Quite a strange little mortal indeed...I like strange.

I thought about this until I overheard Dipper needing to 'talk' to (Y/N). (Okay, I was secretly spying on Dipper, so what?)

Needless to say, I got quite irritated at the current situation.

I planned on visiting her tonight but Pine-Tree is probably going to ruin that, too and blow my cover. All because I've possessed people and tried to take over the world. Come on, I was just tying to have a little fun. Take a joke.

I huffed in annoyance. What I need is a vessel in the physical world-and fast. But how to go about that?

Hmm...guess I could freeze time?

Your P.O.V.

The walk to the Mystery Shack was quick. You quickly grabbed you stuff from your uncle's cabin and continued to the mystery shack. Once in the shack, Dipper and Mabel ushered you up to the attic and locked the door.

     Mabel sat on her bed, looking down and not saying a word. Dipper paced, deep in thought. This being the first time in their room you took a look around.

Dipper's side looked messily professional. Books were strewn everywhere and there was aboard of conspiracies and theories. Mabel's side, however, was VERY girly and bright. She had boy and posters, a couple of stuffed animals, and many other brightly colored objects. We're those packets of glitters taped to her bed?! Cool! Maybe I can persuade her to have a glitter party later.

Dipper's voice interrupted your thoughts. "(Y/N), you should sit down." He motioned toward the desk chair chair. You obediently sat. (Hoping for a treat).

     Dipper, sitting on his bed, took a deep breath. "Alright, so about your dream..." You attentively listened.

     "Where to begin? Bill Cipher is in fact, a dream demon. He is very dangerous and even though you might have had a good laugh with him, he is no good. He doesn't have feelings or empathy toward other living creatures-one can assume that from his track record." Dipper furrowed his brow.

      "He may not look like much but he is very capable. For centuries, he has made unforgiving deals with unsuspecting humans; these deals have often led them to their downfall. He's made deals with my family and even me myself." Dipper looked like he swallowed an extra sour skittle.

      You couldn't believe the words. "What did you make a deal for?" You asked.

      Dipper sighed and glanced away before retuning your stare. "A password for something but that's not important. A couple years back he tried to take over the world, it was called Weirdmaggedon."

      "Wouldn't the whole world know if a higher power tried to take over the world?" You raised an eyebrow.

      "I was getting to that. Anyway, he wasn't able to leave Gravity Falls because of a giant shield around the town. My family and townsfolk rose up to defeat him. I won't go into detail for now just-" Dipper looked you in the eyes. "Be extremely careful in Gravity Falls, I don't want you to get hurt. And if you see Bill again tell me."

      You've had jokes like this pulled on you before, but something told you this was the real deal. Mabel was being quiet and not being hyper, it must have been truthful. Dipper looked about the most sullen you ever seen him.

      Mabel grabbed your wrist. "I agree with my bro-bro. Please don't do something stupid."

      "Wow, that's a lot...um, I'm fine guys, I'll be careful." You flashed a small smile. "That must have been tough for you guys, I'm curious how did you defeat him?" You asked in awe.

      Before either of the twins answered, the room went grayscale.

      "Well, (Y/N), let the man of the hour sum it up for you."

(A/N)- Hey! This story prob really sucks but thanks for reads!
