it’s been like a billion years since i’ve seen anything gravity falls related on my dash... and NEWSIES/GRAVITY FALLS AU? bro. please tell me everyone’s favorite triangle Bill plays a role? who is he? how does he hurt the boys? -fizz💥
So, since Triangle Bill is described as Gravity Falls’s biggest threat, it only makes sense that he would be Snyder the Spider.
Now, Snyder is a dream demon. He’s been around for centuries, only existing in the dream world, which is basically another dimension. To the real world, he’s nothing more than a ghost. Snyder doesn’t like that, so he is constantly trying to break out of his dimension and cause terror in the real world.
Eventually, after getting stronger and stronger, realizing he lives off of fear, he manages to possess a human body and roam around in the real world, terrorizing individual people and getting stronger and stronger until one of Jack and Race’s ancestors banishes him into another dimension.
The only way out is for someone to free Snyder, but the incantation for that is old and the sorcerer that banished Snyder made sure to never write it down.
Furious, Snyder begins plotting a revenge that he refuses to believe will never come. He turns the dimension he’s in into a nightmare dimension where one’s biggest fears come true. He has the power to manipulate the dimension in a way too.
Jack doesn’t mean to free Snyder. In fact, he doesn’t even know who Snyder is. All he knows is that there’s a little golden triangle with one eye drawn in his mother’s book again and again and he has no idea what it means. (Just to be clear, Snyder does not necessarily appear as a floating triangle. He wore a necklace or something with that symbol on and it became known as his symbol. In some nightmares he did appear as shapes and inanimate objects to avoid being noticed).
Now, Jack has no idea what the incantation writing itself in his book means at all. It’s like his mouth just reads it without his consent.
He’d been standing in the very spot where Snyder had been banished from this world and some of Snyder’s fan (some of the locals know Snyder as a legend of sorts) had created a sort of magically binding prophecy that one day Snyder would return.
So anyways, after Jack reads the incantation, Snyder possesses him as Jack is his gateway into the world. In the moment he’s in Jack’s brain, he learns everything about him. His hopes, his dreams and, more importantly, his fears.
He detaches himself from Jack, appearing as a gold and black ghost with no face and a disembodied voice and Jack is immediately terrified, as the only thing in Gravity Falls that had ever really scared him were ghosts.
Ghosts didn’t have rules.
Jack tries to scramble away but Snyder stops him and offers him all the power in the world if Jack were to help him. He surrounds Jack and gets inside his head, showing Jack what he could do if he just said yes. Still, Jack refuses and tries to run, but Snyder has the power to easily put him to sleep, so he does, sending Jack, or Jack’s mind and consciousness at the very least, into the nightmare dimension, making sure the dimension was all of Jack’s biggest fears.
Then he goes to find the man that had done this to him, having no concept of time in the nightmare dimension. The man who’d banished him had owned a little shack in the middle of town.
Along the way, he makes it his mission to terrorize anyone he can, as he gains back his strength by feeding off of people’s fear. Being a demon, he can infiltrate minds and make people see things that aren’t there. As he makes his way to the mystery shack, he uses this strength to make himself appear human, like the original human he’d possessed in the beginning, making himself look less threatening that he is.
But he still has that necklace around his neck. And Medda recognizes it immediately. She manages to warn Race, trying to hide them in the basement because she’s heard the legend of this demon and knows he must be there to seek revenge, inevitably leading to somebody getting killed, but Race instead runs to find Jack with Crutchie’s help.
Crutchie and Race find Jack in a fitful sleep in the woods and they can’t wake him. Graves, who was watching and waiting by, tells them what happened, having been put into his own nightmare for a moment. He tells them where Jack is after promising Race he didn’t bite or harm Jack in any way and then telling them that they had enough problems right now and leaving them alone to check on his flock.
Race takes Jack into his lap and tries to wake him again while Crutchie searches a spell book for some way to get to Jack.
Meanwhile, Jack is trapped in his own nightmares. He’s surrounded by ghosts and faceless people. There’s no sound. He can’t hear and he can’t see. Everything he knows is gone. The sky is red. Everything else is black and white. People are running at him with guns and knives trying to kill him. The scene keeps changing. Walls are collapsing. There are no rules.
He wanders around, trying to convince himself none of it was that scary. He hides in an alleyway, curling in on himself, terrified and unsure of what’s happening.
But soon things take a turn. He hears someone screaming for help. He can’t sit around and do nothing, so he runs towards the person, relieved that he can hear something and wanting to protect someone who might be able to help him in return. As he gets closer, he recognizes the voice.
His biggest fear is losing his baby brother.
Crutchie finds a way to send Race into the other dimension. Race’s holding Jack when he goes in.
Race pulls Jack out eventually, though Jack can’t let go of the nightmare version of Race that just died in his arms.
They all go to get Snyder out of the Mystery Shack. They find it ransacked and Snyder is nowhere to be found.
That’s the first encounter.
Snyder has realized that years have passed and the man who banished him was long gone. So he starts planning to do more damage, basically take over the world and consume it with fear.
Eventually, Snyder does possess Jack and parade around as him for a long time, needing a solid human body to get a little stronger. Race is the only one who realizes that somethings off.
