OK! Sooo.... Dipper isn't actually Dipper Pines... He's Dipper Cipher! The son of Bill Cipher! I know this description is crud.... But it's the best I can do at 9:19PM after a day of dealing with my messed up family. :( -_- ]=<

Welcome one all to Gravity Parnormia! We are very sorry about the in convince about that fire a few years ago and the place had to be closed until rebuilding was finished. Worry no more everyone! The place has reopened once again for all ages! We hope you enjoy your time and come back again soon. We very much await your arrival. I don't own Fnaf and Gravity Falls, also the pictures too. All rights go to their original owners. Was a one-shot, but they wanted me to continue this. Well I am now Enjoy ^^

An Alpha/Omega Billdip.

Dipper Pines saved Mermando's life. What happens when he suddenly turns to a Siren and runs into Bill Cipher?

(Dipper & Mabes be like 15 now!) When the twins come back to Gravity Falls for the Summer. It's Dipper's first time back since the first Summer, but not Mabel's. Every one is surprised to find that their favorite awkward little nerd has become a hot, cool, and hair obsessed bad-boy. Mabel is still Mabel, But Dipper is no longer Dipper. He doesn't even go by his old nick-name anymore, now he's just Michael Pines instead of "Michael Pines, but goes by Dipper". Did I mention... Now he does drugs?

When the search for the supernatural brings Dipper and the rest of the crew on the Mystery Hack face to face with a creature beyond their wildest imagination, things start to get complicated... More than what he seems, the siren casts the crew's lives into turmoil, and it seems he's only there to make things difficult for them... yet there's something else going on beneath the surface... Demons and siren songs, creatures in the shadows and dark deals from the past. Will Dipper be able to restore order to chaos? Or will he be lured into the cold, dark waters? Will the song doom them all? Or will the siren find a reason to change his tune...

5 years after their adventures at Gravity Falls an old enemy appears and thirsts for revenge. Bipper ff♥ (Billdipp) Completed story and edited.
