Hello everyone. I just like to go out and say it...

I CAN'T BELIEVE I'M ACTUALLY WRITING THIS FIC. OOOOHH, THIS IS THE GREATEST HONNOR I COULD EVER GET ON THIS SITE. THANK YOU, THANK YO MINIJEN FOR ALLOWING THIS, I LOVE THIS, THANK YOU.

Now, on to business, in case you don't know, this is based off of The Reverse Pines/falls Au, where in this universe, Dipper and Mabel are the bad guys, filling in the roles of Pacifica and Gideon(at least when they were evil). They are not the most emotional or caring beings, and seek total power and dominance. This is combined with the popular Au, Steven Diamond, where Steven is the son of Yellow Diamond instead. He grew up on homeworld, being mostly raised by Periods, Lapis, And Jasper. He's cold, calculating, and distant towards others. He's always tactically minded, always doing what he thinks is needed to carry out his goal for Homeworld.

Imaging my favorite characters as villains has always been an interesting concept to me, so to be able to write this with permission from the author of the Original Universe Falls, there is honestly no words to describe how I feel, except ecstatic, jolly, and any other synonym for happy.

Now be warned, this fic is going to strive further from cannon than the original story. Funny, because I'm writing two separate Au's into one based off a story that itself is a big Au. The main focus will be on Steven and the twins as they fight to gain power over Gravity Falls and the world. Connie, unfortunately will not be friends with them, as she is one of their main enemies, along side the Crystal Gems. And the trio will not be the most sympathetic, over time, they will soften up a little, though don't expect that to be anytime soon.

So, without further ado, here comes Reverse Diamond Falls.

I own nothing, not even the Au concept. All rights go to MiniJen, Alex Hirsche, Rebecca Sugar, and whoever else worked on those two shows.

A lifetime ago….

Within the dark corners of the uncharted woods, a figure hid in secret. A figure shrouded in the dark. He knew too much about what was at hand. He knew that the power and knowledge he held was dangerous, and if in the wrong hands, it could spell disaster for the quiet town, maybe even the world. Forces were against him; higher powers were out to get him. He was sure of it! He knew that only he himself could keep the secrets safe.

Thump. Thump. Thump.

His heart beat went faster and faster, like the drums of a marching band. Each one seemed to get louder and louder as he tried to move. He couldn't. He was frozen in fear. He knew that one false step could trigger THEIR presence.

Thump. Thump. Thump.

With every beat, he began to drown in cold sweat. His stench already was attracting a few small insects. He knew that he didn't have much time left. He needed to hide it. He reaches into the confines of his coat, perhaps the only safe spot left in the town, a pulled out a large, read Book with a golden hand. In the center of that journal, was a large, black 3 on it. He opens it up and writes something down before closing it, hopefully for good, as he grabs the shovel he brought with him.

Deciding not to waste any more time, he begins digging. More and more dirt begins to rise from the ground, and the deeper he gets, the more anxious he becomes. This was it. This was the final one. All he had to do was complete his task, and he could say goodbye to all his problems. Finally, he could get back to his normal life. No more mystery, no more dark secrets and conspiracies, and best of all, no more …

Crash. Crash. Crash.

Something began to make noise. And it wasn't a quiet noise. It was big, loud, and inhuman. Nothing could ever compare. With every step that was taken, it was like a mini earth just waiting for the moment to destroy everything in its path.

Stomp. Stomp. Stomp.

Louder and louder the stomps get, and the more the man begins to worry. He had finally made the hole deep enough. Now all he had to do was cover it with the book inside and he would be free.

Stomp. Stomp. Stomp.

The man had begun to replace the dirt, but now the stomps were getting closer. It was like with every second that he moved, the noise somehow knew where to look. The man knew that his time was almost up, and he was only know halfway done. He knew it had to be done completely, or else they would find it. And if they found at least one of these books, untold amounts of chaos and carnage would be unleashed,

especially in the hands of HER.

STOMP. STOMP. STOMP. STOMP.

The man had finally done it. He had finished the task. Unfortunately, right as he did, a tall, foreboding figure hovered over him. It looked at him menacingly. It was if the figure was observing him. And if it was, then said figure was not impressed.

With a single wave of the giant's massive hand, it threatened to squash the poor man. Fortunately, the adrenalin kicked. With a body full of energy and the pure will to live, he leapt out of the way, and ran into to the woods. Faster and faster he ran, he dared not to looked back. He knew he position far too well. He was a mouse, a little, tiny, scared and insignificant mouse playing its part in the game. He knew if he stopped running, then he would lose, and the all-powerful cat would win, in more ways than one.

So he ran. And ran, and he ran, and he ran, not caring about how exhausted he was, nor about the blister forming at his feet. With each step it felt as if needles were being jammed into his legs. At any moment, he felt as if he was going to collapse on the spot.

But he found the strength to keep moving. He was not going to let them win.

At long last, he had made it. Soon, he had ran so far and deep into the woods that even the monsterous stomps of the giant were nothing more than slight taps on the ground. All the man could hear was the voice of said creature, which even from the distance he was at, was still loud, vicious, and demanding.

"Find him! Find that human! We need to learn what he knows! Find him now!" It screamed as she ranted and demanded in anger.

Oh how the man felt foolish. Of course their was no way it would be this easy. He couldn't just hide the journals and escape. That would've been too easy. He should've known they wouldn't just let him leave, they've been here for centuries, of course they wouldn't let something like this go so easily.

He knew this was just the beginning. He would have to hide within the shadows. He couldn't just leave with them after the knowledge, no that would have been selfish. This was his home now, and he would do what he could to save it from the destruction that would soon come to pass. But if he was going to stop them, then he had to do it alone. He couldn't trust her though, nor her little group of friends. Never again would he trust their kind, especially not after what she did. And everyone in town would freak if they truly knew what this little town was really all about. He knew all to well the consequences of trusting someone of this town.

For in Gravity Falls, their is no one you can trust.

"Come on! When are you going to trust me to take the lead?" complained the voice of a thirteen-year-old girl as she walked out from a big light blue tent. Said girl was wearing a sky-blue suit with a black skirt, along with black fish net stockings and black heals. She had chocolate brown hair as she wore star like earrings, along with black eyeliner and blue eyeshadow that made her look slightly sad if you really looked at it. Her voice sounded young and very childlike, though a bit snobbish and rude.

"Uh, the same day I can trust you not to use your magic to terrorize all of our cliental away." Said the voice of an adorative 13-year-old boy. He wore all black pants, shoes, socks and collar shirt, over it being a light blue vest. He also wore something of a cape, half of it on his front, and half on back. He has short but messy chocolate hair, which slightly covered a big birth mark that look something like the big Dipper. His voice was also young, but it portrayed some sense of maturity and boldness. Said boy was shooting an irritated look at his twin sister, knowing that at any moment, she would say or do something that would show she wasn't listening or prove his point, or both.

Mabel at the moment was walking pass a young chubby kid with light brown hair. The kid looked like he was going to say hi, but before he could, Mabel waved he hands over him, emitting some sort of blue flame from it as she dead. In that instant, the kid was completely covered in snakes. He ran off, screaming in terror as he tried to shake off the little green horrors. That left Mabel laughing hysterically in his displeasure, while also unknowingly proving his brother's point. "I'm sorry, were you saying something?" She asked, finally calming down to acknowledge her brother.

Dipper just lets out an irritated sigh as he brings his hand to his head. "This is what I mean Mabel. You don't have the brain power to acknowledge anything other than your own petty amusement. Therefore, you never take the lead. That's why I'm the mastermind here." He smirks at his own ability.

"Oh please." She scoffs in disbelief. Lately her brother has been getting stiff, and well it did work when they were completing important tasks, it made him a really big bore. "Don't tell me you don't find this stuff at least the slightest amount of amusing. Besides, we are like, the most powerful kids in the world, and what's the point of being a kid with powers if you don't try to have fun with them?" She questioned as she got a little too close for comfort as she looked at him face to face, with their noses touching each other.

The boy shows no discomfort as he simply stares at her. "Having power is one thing Mabel. It's a whole other thing to master it, control it, to bend it to your will." He seriously stresses as he moves from his spot and moves forward. "You know what we're really here for, right Mabel?"

"Yeah, yeah, yeah, to find the mysterious power that our Great uncle Stanford talked about in his journal and use it to conquer to world, blah, blah, teacher's pet." She murmured that last part before continuing. "I get it, I know about it, but face it, that Journal has left no close on where to find it, and we've haven't seen our dear Great Uncle since he disappeared on us two years ago." Mabel bluntly stated. "Come on, we have this power, everyone already adores us, and we're rich beyond measure. We could run this crummy town anytime we want. Why not do it now when the going is good?"

"Mabel, you know our power is but only a small fraction of what it could really be. Imagine" Dipper say as he grabs Mabel by his side and slightly gets a little too excited in explaining. Mabel just uncomfortably listened as he ranted on. " Powers from beyond the earth, beyond our universe even! Powers to move mountains and create earthquakes with a single stomp! Powers that can defy the what we understand about the normal physical plane, abilities we can't even comprehend because our primitive minds are…." He got louder and louder as he continued to rant. He probably would've continued to do so if it wasn't for his sister's timely inturrption.

"SNORE.., Wait what was that? I couldn't understand. You know I didn't take the nerd language class this year." She mocked as she demeaned her brother. "Fine brother, you win, we'll do this your way for now, but mark my words that we'll come back to this. You can't be Great Uncle Stanford. We need to do this our way." She said as she tried to sway her brother's thinking.

This just gets Dipper mad. "Mabel, Great Uncle Ford was the greatest man I've known. When he saw an opportunity to take power, he did. He let nothing get in his way. He let nothing to chance. That's how he got so far in life. That's why we're so far in life Mabel! Without him, we'd just be petty orphans begging for scraps of garbage just to survive! That's why I'm going to follow his lead, because it's the only way to succeed." He ended as he made his way back to the tent.

Mabel just sighed. When they were younger, their parents died of some unknown accident, leaving them orphans for most of their young lives. They lived in a ratty orphanage for about a year. That was the cruelest part of their lives. Nothing could compare to the pain of their parent's death, but living in that cruel place was a close second. Everyday was miserable for the twins, abusive staff, poor housing, hardly any food, though the one to receive the most torment was Dipper. They were constantly reminded them of how weak they were in that situation. That's when the Pines twins made a pact. They promised to never abandon each other, They promised to rise together, to stay strong together. And more importantly, they promised themselves to never be weak again.

That day finally arrived when came the appearance of their Great Uncle Stanford. He was a world renown show man with a once promising career as a scientist, who also for some reason had six fingers. He had heard about two possible young relatives in need of some care, so he came as soon as he heard and took them under his wing. But while the Pines twins gained a guardian, Stanford gained something a little more than family, heirs and apprentices. Realizing the great opportunity, Stanford taught them everything he learned about the weird side of the world. Apparently, he was a master of something that could only be described as weird. He trained them in the ways of the weird, teaching them how to summon the dark and rather uncanny power. Not only that, he'd taught them the art of power grabbing, both in the literal and business sense. While Mabel loved this grand new power an opportunity, Dipper was ecstatic and relished in it. After a year of torment and abuse, the power, the knowledge, the opportunity, it was more than he could ever dream of. And Ford couldn't have been prouder. Dipper was a natural prodigy in both intellect and weirdness, so it was pretty obvious who the favorite was.

That's how they lived most of their lives, until one day, he just vanished, no where to be seen. All he left them was a note as well as a book with a large number 2 on it. All the note left was instructions on what to do.

Find the portal.

Gain the power.

Cease his power at all costs.

Do what needs to be done.

Stomp on all those who oppose you.

And trust no one

Ever since that day, they've been on their own, trying to fulfill their dear Great uncle's wishes. Dipper was determined to do so, not just for the power, but for Great uncle Stanford. Mabel was often uneasy at this. Sure, she was all in for gaining ultimate power, but those words really stuck to her.

Trust no one.

Mabel could only hope that it didn't refer to each other.

"Trust me, my Diamond, our routine checks on Earth will begin shortly." Said a nasally, high pitched voice. She was tall and green, with sharp shades of black on her shoulders, waist, and legs. She had a bright green Gem on her forehead, where also lied a clean, clear visor on her eyes. She had a light yell head of hair, which was somehow shaped into a triangle. She spoke with a rather persistent tone, almost as if she was trying to please the one she was speaking to.

"Excellent, Peridot. You have performed your duty's well. Head back to the ships main controls and prep for our landing." Said an authoritative, blunt, but young, voice. He wore an all yellow suit, yellow shirt, boots, gloves, and even a cape, all various shades of the bright color. He had a young build, slight chubby but somehow also buff enough to tell you how strong he is. His hair, was a little strange. At the back of it, it was curly with swirls and swirls of circles, but at the front, it shot up, showing of three prominent spikes at the head. Probably his most uncanny feature, however, was the large, yellow Diamond in the center of his chest. His entire aurora gave off something of a royalty vibe, if not, at least you'd know he was someone important.

"Yes, my Diamond." Peridot bowed respectfully as she took off. As she did however, she let out an elated chuckle. She loved her Diamond with a passion, and although the original was no longer with them, her "son" was so much like her in many ways. She just couldn't help but be happy serving him. She was given the honor of educating him in the ways of Homeworld, in the ways of the authority. She, a Peridot, teaching a Diamond! There was no greater honor than that for her. She could only hope that she could teach him to be just as great of a leader as the original.

"Uh, seriously, why must these trips be so tedious? And why must we go to Earth so often? If Homeworld hates it so much, why can't we simply…." He starts complaining before he is interrupted by an unexpected force. The young Diamond looked around, skeptically, but not scared. All he could was watch as the white and orange blur surround him as it prepares to make its move. All the Diamond does is close his eyes as he prepares for the assault.

"AGHGHHHHHHH!" The blur yelled out as it made itself clear to she as it launches itself at the twelve-year-old child. It had a large orange body with tangerine stripes across her face and arms. She had a big bundle of fluffy, white, messy hair that reached the floor. Her uniform had some had various shades of dark orange and brown. She seemed to wear some sort of brown cape that went a little passed the shoulders. Most interestingly, she had a small, orange gem right on her face where her nose should have been. She was fully ready to take out the little Diamond. All it would take was one good tackle and he was good as dea….

Smock

Before she could reach him, he reached out his hand and grabbed her fist, somehow stop the full force of the incoming Jasper. What was even more impressive, was when he somehow lifted the hulking gem up and slammed her on the ground while carrying her overhead. She slowly opened her eyes to acknowledge exactly what had just happened, to meet the stern gaze of the little ruler, who seemed completely unbothered by her attempted assault.

"You know Jasper, one could get the idea that you're going easy on me. The next time that you plan to assault the one in charge of you, you'd better come to me with an actual challenge." He plainly stated as he watched her get up.

"Impressive as always, my Diamond" she humbly bowed as she got to her knees. The Diamond just shrugs this off as he makes his way towards the lower chambers. This confuses the Quartz as she follows him. "Is there something bothering you, my Diamond? I heard about you troubles as you walked in." She says with a little concern. The Diamond just turns around, and grabs the orange Quartz by the neck collar.

"If you intrude upon my personal thoughts again, I'll have you bubbled for the next century, got it!" He warned as he lets go.

"Y-yes, yes, of course, my Dimond." She complies as she leaves him to his business. After the war, Jasper was assigned to the original Yellow Diamond to serve. It, was a little hard for her to adjust. She was the most loyal subordinate to Pink Diamond, and now that she was gone, nothing could ever ease that pain. At least until Yellow Diamond promised her revenge. Earth was the very reason why her Diamond was gone. Earth was the sole reason why the proud race of gems had hit a slump in both culture and new gems. Earth was the reason why she was hurting so much on the inside. But Yellow Diamond promised recompence. She promised that Earth would get what it deserved. But now that she too was also gone, it was up to her to make sure the new Yellow Diamond fulfilled his dying "mother's" mission. It up to her to her to teach the future head of the court how to be tough, how to be ruthless, how, under no exceptions, should any mercy be done upon the earth.

Not only for the sake of his "mother", but for Homeworld, for her colony

For her Diamond.

The little Diamond just continued to walk along the halls of the big and vast ship. It had been awhile since he had been here. He only went to this room for one purpose: to remind himself of the mission.

As he makes his way towards the main cell, he spots another familiar gem. She was a tall one, with blue skin color and dark blue messy hair that reached a little way past the chin. She wore a long blue dress, with various shades of blue, thought the only thing that contrasted that was the yellow diamond in the middle of the outfit. She also had a small, tear like gem in the middle of the top half of her back, though on it was a big crack down it. Though, unlike the other two, she wasn't so enthusiastic to see him. In fact, she seemed nervous to look at him, as if the bags under her eyes were any indication. She seemed rather miserable.

"Greeting, my Diamond, how may I assist you today?" the lanky blue gem greeted as she bowed in fear.

The Diamond speaks indifferently. "How is the prisoner?"

The gem, known as Lapis, speaks out. "He hasn't said a word all day. He's completely silent. He didn't even try to fight me when I induced his daily nutritional shot. It's like he's finally relented."

"I see. Let me in, I wish to speak to him alone." The Diamond spoke with no infliction with what he was thinking. The Blue subordinate could only comply as she does what she is told.

The Diamond just walks in and dismisses the water Gem, who sighs in relief.

During one of their surveillance checks on the earth, they came across a mirror. Peridot picked it up, hoping that it contained information suitable to teach the young Diamond. When it didn't work, the young Diamond pulled out the Gem that was in the back, revealing it to be Lapis. She was grateful for her release, and willing to do anything for her savior. Since by know her place in Blue Diamond's court was gone, and seeing how willing she was to serve him, he kept her, not as the Lazuli she was though, she was more like a Pearl, a servant, a slave. That's how it's been for the last 6 to 7 years. She would say she was fine, but in truth, she didn't know how to feel. The young Diamond himself didn't do anything bad to her personally, in fact, he was rather ignorant of her presence, she understood that though, he's a leader after all. But the other two, they made her life almost unbearable. They treated her worse than a pearl, taunting her constantly about hoe the "mighty had fallen." She would never regret helping the one that saved her from her prison, but she wondered if it had been worth it.

Within the chambers came a hall full of various cells. Each one had an electric field around them, to stop any trapped Gems from escaping. They were all like that, except for one specific cell. The cell containing the only other human on board. He was in a write straight jacket and had a long, brown beard that was only matched by the hair growing on the back of his head. He just looked ahead, showing no clear expression or emotion, except for surprise. It was rare for the old man to see him around here.

"So, what are here for this time?" The prisoner said with a straight forward serious attitude.

"What's wrong? Can't a half carbon based life form meet half of his organic doaner?" The Diamond said plainly, if a little sarcasticly.

"Steven, you know that the word is "son" and "father" right? Or is the almighty Diamond too smart to learn the language of his own people?" His father snarked.

The little Diamond banged his fist on the wall outside of the cell. "Half" he emphised. "Half of my species is from Earth. My true people are the Gem's of Homeworld. I am Yellow Diamond! I am the future of my court! I am..."

"Oh, save the propaganda for the torture sessions. " His father interrupted. "You wouldn't have come hear just to brag about yourself to me, so again, what do you want?"

The Little Diamond lets out a little smirk before continuing. "You know, its funny. My Homeworld always hated earth since the war. They wanted nothing to do with it. My mother was the one who commissioned the Cluster in the first place. She wanted nothing more than to see this world nothing more then space dust floating aimlessly. But..." He then opens the cell and gets up close and personal to his father. "you just had to be one of the only few that weren't afraid of her. You showed her the true value of this planet. You showed her, the toughest, the greatess, and the most fierce leader of homeworld, that this planet had a future, in the hands of the Diamonds at least." The little Diamond laughs at the irony. "You did save the Earth father, saved it for Homeworld to use. How does it feel to know that you helped the greatest conquers of all time take over your home world?" He smiles wickedly at his father.

The man known as Greg Universe lashes out his response at that. "Steven! Your talking about war! It won't be like the first time around! The planet will fight back! Steven, lives are going to be lost, both human and Gem, and neither side can survive another Gem war for the planet! You don't have to be apart of this!" He pleaded

Steven angrily picks up his father before throwing him against the wall. "I don't have to be?! This war has been going on for much longer than you know, father! Thanks to you, I inherited this war, and by the will of the authority, and by the words of my mother, I will complete her task!" He calms down for a moment before continuing. "I know it won't be like the last time, father, that's why your going to help Homeworld once again." He smiles dasterly before setting him down.

"Why would I help you! I won't let you make the biggest mistake of your life son! Besides, how would you even get me to talk? I'm not afraid of you or homeworld." His father states.

"Oh, because you'll be doing this for your precious Steven Diamond Universe." He teases in a mocking tone. " And I may have had Peridot place a little truth serum in today's daily nutritional shot." He laughs at his own cleverness.

"You diiiii..." His father trails off as his eyes widen and his speech begins to slur. His expression is now completely blank.

"Good. Now I know where you came from, and I know that little colony you call home has something of value to Homeworld..." He smirks once again before regaining his serious composure. "So tell me, what is so special about Gravity Falls?"

Whoa, that is the most words I have ever written, and I bet the next one will probably be longer.

Thank you once again MiniJen for allowing this. I'll try to live up to your standards.

Next time, our pro, or rather, Antagonist meet, and lets just say the first encounter isn't all going to be hugs and rainbows.
