Disclaimer: I do not own Fullmetal Alchemist or Gravity falls. They belong to Hiromu Arakawa and Alex Hirsch respectively. I only own the OC characters.

Description: Okay, so, quite a few things. This story will actually take place in a crossover that I've been planning to write for quite some time. I'm obsessed with both FMA and Gravity Falls that I decided they needed to mingle. The crossover was also going to be written for me to introduce two main OCs I wanted to write into the story of Gravity Falls. When I do plan on writing this, I'm going to write the story as an anime, and as a continuation of Gravity Falls; you know, after the show ended. Since this story takes place in the crossover, there will be things that are mentioned that don't make sense when you read them. They're meant to give you context clues about what has already happened. However, this story is not a part of that crossover storyline. I actually have something different planned that has to do with a certain dream demon that we all seem to love and hate.

If you don't like this kind of crossover, then don't read it. But if you are interested, I will tell you that this is the first time that I'm writing a crossover like this. Please let me know what you think of it.

Just to give you a picture in your head, the anime that I'm making Gravity Falls into is the same kind of animation that's in Fullmetal Alchemist: Brotherhood.

Edward didn't expect to wake up in a place like this. He should have been in his makeshift bed on the floor in the spare room of the Mystery Shack. Not in some square white space that was completely foreign to him. He was thoroughly confused.

He found himself on his knees, his arms and legs pulled back behind him. His wrists and ankles were secured to a metal pole sticking straight up in the center of the room. To his dismay, he learned that he was also completely naked, his bare flesh knee resting on the cold surface of the floor. He lifted his head to gauge his surroundings, his loose blond hair shifting to his shoulders. There was no one else in the room. Was he the only one who had been taken? Where were Katelyn and Rosalin? Where was his brother?

He began shifting in his chains, their clinking sound echoing around him. He tried with all his might to touch his hands together, but whoever kidnapped him must have known about his alchemic abilities, because he could not get his left hand to slap against the cold metal of his right. His anxiety began to rise. If Alphonse or anyone else was in the area, he had to get to them. He did not like being trapped. It made him feel helpless.

He jerked his head up at the sound of a creaky door. In front of him, a few feet away, the seamless wall gave way to reveal a doorway opening from outside the room. The man he saw made him even more confused. He was tall and lanky, wearing a blue suit jacket over a white shirt, with matching blue trousers. He wore shoes on his feet that had several laces going across in a zigzag pattern. Edward remembered Katelyn telling him that these were called "tennis shoes." His skin had a dark bronze hue, his hair a darker brown, and his eyes were a deep, velvety blue, almost matching his outfit.

As he came further into the room, he was followed by more men wearing various styles of clothing, their builds ranging from heavyset to lanky, like the man in blue. Edward did a quick count and realized that there were seven in all, not including the man that appeared to be the leader. The young prodigy cursed his luck. Even if he did manage to free himself, he didn't know if he could take on eight people at once. His odds of escaping were minimal.

He increasingly felt more uneasy when all the men grinned at him as if he were a new toy for them to play with. Well, except for the one in blue. He stared at the teen with calm intrigue. Ed didn't know if that was better or worse than the expressions of the others. His discomfort spiked again when the blue-eyed man walked forward, towards the chained alchemist. Ed held himself back from struggling or pulling away when the man lowered himself to one knee in front of him, until their faces were only a few inches apart. Ed said nothing, and held the man's gaze, trying not to feel intimidated in any way.

"Edward Elric," the man said, his voice smooth and silky. "I never thought I'd get the chance to meet you in person."

The blond stared at him. He couldn't hold back his dumbfounded expression. No one else should know that he existed, besides those who lived in the Mystery Shack. "You know who I am." It was more of a statement than a question.

The man chuckled. "Of course I do. You're not the only one from your world who's travelled to this one." Lifting up his hand, he directed the boy's attention to his open palm. "In fact, you're not the only alchemist either." Ed gasped. The man had a transmutation circle tattooed on his palm. He had never seen one like it before, but he could make out that the array was earth-based. This guy was an earth alchemist.

"No, that's impossible," Ed said, his expression filled with shock and disbelief. This world hadn't developed the science of alchemy. There should have been no other alchemists that existed in this world besides him and Alphonse. "W-who are you? How did you-"

"Oh, where are my manners?" the man interrupted. "My name is Léon." He glanced behind him at the other men. "You'll learn the rest in time." His gaze shifted back to the young prodigy, who was clearly shaken to his core. "I am from your world, yes, but not the same time. Alchemy has come a long way since the 1910s. It really is amazing." He stood up, Ed following him with his gaze. He was doing his best to try to take in what this guy was telling him. He didn't think he could take any more astounding discoveries of what the universe actually was. Katelyn had done her best to explain it to him, but there were still some things he couldn't quite believe.

"We," Léon continued, gesturing to his entourage behind him, "have a proposition for you, Edward. You see, I heard that a very famous alchemist, years ago, discovered the secret ingredient for a very powerful substance. When I made my way to this world, and found out that that same alchemist was here as well, I couldn't pass up the opportunity. As luck would have it, my ultimate goal was finally within reach."

Ed swallowed, composing himself. "And what goal would that be?" he asked in a serious tone.

Léon looked down at him. "The creation of the Philosopher's Stone."

The young teen's eyes widened. How could someone claiming to be from the future know that he, the Fullmetal Alchemist, had found a way to create the Philosopher's Stone? He couldn't wrap his brain around it, and he was supposed to be one of the smartest alchemists out there. But he reminded himself that he had more important things to worry about. "If you just wanted to ask me something, why'd you have to bring me here?"

Léon sheepishly rubbed the back of his neck. "Yeah, sorry about that," he said. "It's just that," he lowered himself again, "any smart alchemist knows not to share his secrets. I hope that we won't have to use more drastic measures, but that's entirely up to you."

Ed's expression changed to one of defiance. "I won't tell you how to create the Philosopher's Stone," he said vehemently.

Léon appeared to be a little bit flustered. "Oh, no, no, no. I don't need you to tell me just yet. I only wanted to offer you to work with us on our little project. Your skills would be invaluable to my team and I. Of course, we'd have to work in secret, but that shouldn't be too difficult. Once we have what we need, we can all do whatever we want. Who knows, you could even get your body back." The lanky man stood up again, a slightly hopeful look on his face, missing the teen's hateful glare. "Well, what do you say, Edward? Do you agree to work with us?"

Ed was awestruck at the fact that the bastard had the nerve to ask something like this, especially with that last comment he made. "You think I would leave everything behind to go galloping off with you freaks?" Léon's face fell at the words. "Even if I didn't have to restore my brother's body," Ed continued, "I can't risk something as powerful as the Stone falling into the wrong hands. Sorry, but you're out of luck."

Léon's expression darkened. The sudden shift in his mood made Ed almost regret his words. Almost. The man's face was truly murderous. The teen realized that he would soon find out what kind of man Léon truly was. The man in question sighed, closing his eyes and crossing his arms. "I have to say that I'm disappointed, Edward," he said, as if he were reprimanding a child for doing something wrong. "I would have thought you'd see reason." He glanced behind him and nodded at one of the men standing there. Ed's heart sped up when one of the heavily built men made his way over to the wall on his right, and started rummaging in a box he hadn't noticed was there before.

"I had hoped we could do this the easy way," Léon said, grabbing the boy's attention again. Ed's fear built up inside him, and he began to breathe heavily. The man standing before him had him trapped in his withering glare. "Now, it seems we'll have to... persuade you." Ed didn't like how he said "persuade." It made it seem like it was a death sentence. Léon went down again, his nose a mere hair's breadth from Edward's. "And the longer you refuse," he said in a dangerous tone, "the more painful it will be for you."

Edward visibly flinched at the loud cracking sound. He looked behind him to discover that the heavyset man was holding a long whip in his hand. True terror finally seized him. He cast a pleading look at Léon, who promptly ignored him, standing up and motioning for the man to begin.

He felt the pain more than he heard the whip. It lanced across his back, white and hot. He wanted to scream, but he bit it back, only letting out a pained grunt. After the second hit came, he could feel his blood dripping down his back. After the third hit, he couldn't hold back his screams anymore. The biting, stinging pain blossomed all over his backside, even hitting his flesh arm and foot. He let out an anguished cry every time the thick leather met his skin. Most of the noise surrounding him had faded to static. Soon, the flesh on his back was soaked in blood, some of it pooling onto the white floor. Ed stared at the small red puddles in between lashes as if they were the most fascinating thing he had ever seen.

He faintly noticed that the whip had stopped, but the pain still lingered. He was panting heavily, his heart racing a mile a minute. He vaguely registered his chin being gripped, his head lifted from its bowed position. He found himself face to face with Léon. "It will only get worse from here, Edward," the boy heard him say. "Think carefully about the choices you decide to make." With that, the lanky man let Ed's head fall, and the sound of a door slamming was heard not too long after. He heard nothing else. He was left alone.

It took him a minute to steady his breathing. He tried not to shift around too much. The wounds on his back still hurt, and he didn't want to aggravate them any more than he had to. It reminded him that he was completely trapped. He couldn't get himself free, and he would fail in trying to escape even if he got loose from his bonds. Instead, Edward hung his head, the strands of his hair falling around his face. He could only hope that someone would find him soon. He really didn't want to know how much worse this could get.

Author's Note: Okay, okay, before anyone freaks out, I know that there are a lot of things that don't make sense. However, I can't reveal everything that's going on right this minute. It all has to be revealed piece by piece when I actually officially write the Gravity Falls fanfiction and crossover. For now, all I ask is that you roll with it.

I know it's been a few days. I've been in band camp, so I've been going to my school every day for that. Being in marching band is hard, especially now that I'm a drill instructor. I don't know if updates will be slower and more sporadic. With marching season and school coming up, I also have to start applying to colleges. It's my senior year of high school. I really hate doing it, but since I have three AP classes again this year, I may have to take another hiatus because of school. But who knows, we'll just have to see. Besides, school hasn't started yet.

Again, please let me know what you think of this. I've been really excited to show this to people for a long time, so I'm worried about what people's reactions will be.

Praise is appreciated and constructive criticism is encouraged.

You are all beautiful people;)
