Hi! So, this is an idea that has been raging on in my head for a REALLY LONG TIME and I just couldn't hold it in anymore. I am a HUGE fan of both Gravity Falls and Steven Universe, and the gem AUs I've constantly read and seen have given me so much inspiration. This is an idea that takes place after the events of Weirdmageddon, when Dipper and Mabel defeat Bill. (I know the Gravity Falls finale hasn't come out yet, but this an AU, so please just go with it.)
In this verse, Dipper and Mabel are hybrid gems. Like Steven, they are made of organic matter and their skin and hair color is the same, but they can use their own gem powers like regular gems can, including fusion. And if their gems get cracked or shattered they will die.
In this AU however, Dipper, Mabel, and any other hybrid gem were born differently than Steven. The gem war still happened and lots of gem technology, artifacts, and temples were left behind like they were in Steven Universe. In this world however, the gems that stayed on Earth spread out all over the planet to help interact with humans better and learn even more about the earth itself. The gems even figured out how to use some of the remaining gem technology to help the earth rather than harm it. They took all the gem substance the injectors from the kindergartens contained and used it to create a medicine that would help humans successfully give birth if their babies were originally going to be still-born. It worked, but what the gems didn't realize was that those babies were all born as hybrid gems because the gem-substance in the medicine literally incubated within the mothers' bodies and became a part of the babies that had yet to be born. The procedure didn't hurt the mothers or cause any bad side effects, but the gems were unsure of what to make of all the new human/gem hybrids and were even worried about if what they did was truly a good thing or not.
The anomalies in Gravity Falls are made up of more gem-related stuff, which Ford has been investigating since arriving in Gravity Falls. Bill and his friends from the Nightmare Realm are all corrupted gems. You see, in this AU, when Homeworld was looking for another planet or even dimension to repopulate, they found the Nightmare Realm, however they didn't realize how the horrible dimension worked until after they started gem production. They quickly abandoned and sealed off the dimension, however the gems that they already implanted continued to incubate while suffering the effects the Nightmare Realm was having on them, thus they were all born as corrupted gems. Bill is the most powerful of all of them because his gem was planted and then emerged first, and after learning that Homeworld abandoned him and the others, he set out to take revenge by shattering normal gems and planting multiple sets of mixed shards in his dimension, causing them to incubate and emerge as fusion monsters.(He most likely made deals with the gems he turned into fusion monsters by speaking to them through the mindscape and then tricking them, similarly to what he did to the characters in Gravity Falls, but I'll leave up to your interpretation to how he then got the shattered gem shards into his own world.)
Wendy is also a half-gem like Dipper and Mabel, except she is a fusion. Soos, Stan, and Ford are all normal humans but like I said, Ford has been studying gems for years. Stan learned a little about them by observing the weirdness around Gravity Falls and reading Ford's journals while trying to reactivate the portal. Dipper, Mabel, and Wendy are all gems, so that's how Soos got involved(also because he lived in Gravity Falls his whole life).
(Last thing)Dipper's gem is a moonstone and Mabel's is a sunstone. Mabel has the power to create and shoot powerful balls or waves of energy, but she easily tires out if she uses too much power or creates really large bursts of energy. She also has healing abilities. Dipper on the other hand, though he may seem useless in combat, has the power to amplify and strengthen any kind of energy, especially Mabel's, meaning that they are both much stronger when they fight together. He also can create force fields and has dream powers; he can bring himself and other people inside of one's dream, create lucid dreams, or even speak to others while they are dreaming. For their gem weapons, Mabel has a grappling hook and Dipper has a sword.
Everyone looked around, finally taking in how Starlite's last attack had nearly destroyed the entire town, however they all couldn't help but smile and cheer in victory. Even Gideon and his prison friends were cheering. Dipper was then shown helping Mabel stand up and the two of them smiled at each other, happy that they won.
Dipper – We did it, Mabel.
Mabel – You KNOW we did it, Dippin-sauce!
Soos then quickly came over and hugged the twins, followed by Wendy, who hit their shoulders playfully and proudly.
Soos – That was amazing, Dudes!
Wendy – I told you, when you two work together, there's nothing you can't do.
Stan then came over and patted Dipper and Mabel's heads happily and proudly.
Stan – Ha! You can say that again! That was the greatest thing I've ever seen!
Ford – It truly was.
Ford was then shown walking over as well. He kneeled down to Dipper and Mabel and put both of his hands on their shoulders, smiling proudly at them as well.
Ford – I've seen all sorts of things ever since I first came to Gravity Falls, but nothing more impressive than what you two just did. I'm so proud of you, Dipper and Mabel.
Dipper – Thanks, Great Uncle Ford.
Mabel – GROUP HUG!
Mabel hugged both Dipper and Ford, startling them both at first. Stan, Soos, and Wendy then joined in on the hug as well, which made Dipper and Ford smile and relax as they hugged their family back. They all then started laughing.
Soos – I love you guys.
Suddenly, a black hand broke free from the rubble that seemed to lie on top of it. The Pines family and the rest of the town immediately gasped in shock as they turned their attention towards whatever was rising from the rubble. Bill was then shown moving the rest of debris on top of him off and struggling to stand up. Much like everyone else, his entire body was dirty and seemed to have scratches and bruises all over it. However, he also looked pretty mad since he immediately began glaring at the Pines family.
Bill – This… isn't over…
The Pines family then began glaring back at Bill.
Ford – Give it up, Bill! You have no power left to fight and your entire army has been poofed! You've lost!
Bill – Don't think you've won yet, Six Fingers.
Stan grinned and rolled his eyes.
Stan – Oh yeah? And why not? In case you haven't noticed, these two scamps just kicked your sorry triangle gem butt. What are you gonna do now? Try to enslave us with some new weird kind of gem magic?
Bill continued to glare, but then his eye changed to look as if he was grinning.
Bill – Maybe not alone. But if I had a little help…
Bill rose up his right hand, and Dipper was then shown being lifted into the air and summoned towards him.
Dipper – Wha-? What the-? Guys!
Mabel – Dipper!
Stan – Kid!
Soos – Dude!
The others reached out to Dipper horrifyingly as Bill brought him close to him. Dipper began to struggle and thrash as Bill continued to hold him in the air.
Dipper – Let go of me!
Bill – Whoa, whoa… easy there, Pine Tree. Don't go getting so feisty just yet.
Mabel – Put down my brother you dumb-face!
Ford – Bill! What do you want with him?!
Bill – Relax, Sixer. It's just a small request.
Wendy – What kind of request?!
Bill ignored Wendy and turned his attention back to Dipper, who stopped thrashing but continued to glare harshly at him.
Bill – Pine Tree, listen, fuse with me!
Dipper and the rest of his family's expressions turned to ones of pure shock.
Dipper – WHAT?!
Rest of Pines Family – WHAT?!
Bill – I must admit, while I did underestimate you and Shooting Star, I always knew that a sunstone like her possessed incredible energy. The only flaw is that she expends it in big bursts and tires out easily. But, a moonstone like you holds the power to amplify energy itself, increasing its strength and size by massive quantities. A power like that is just what I need.
Dipper – I'd never fuse with you! There's nothing more you can do, Bill! It's over!
Bill – Oh, but that is where you're wrong, Pine Tree.
Bill then pointed up at the sky, where the rift was visible.
Bill – I may be powerless now, but as long as that rift remains, the fabric of this world will continue to crumble. In just a short amount of time, this dimension will completely tear itself apart!
Dipper, his family, and the rest of the residents of Gravity Falls all gasped in shock and horror. Wendy then glared at Bill again.
Wendy – You're insane! Fusion is way too dangerous for a pure gem to perform with a corrupted one!
Bill – I suppose that's true. After all, pure gems can't match the massive wavelengths us corrupted ones posses. It's possible we may even just absorb all their energy. But if that's the case, with your amplifying abilities, I could gain enough power to keep this world completely stable.
Stan – Like we'd ever let that happen!
Dipper – Yeah! Besides, you'd just keep dominating over everyone and everything anyway!
Bill – It would be a small sacrifice. I mean, what sounds better? Me having supreme rule over your dimension, or having it be completely destroyed?
Dipper continued to glare at Bill, who then laughed a little.
Bill – Look at this! You sure take after old Sixer, Pine Tree. Tell you what… Let's make a deal. If you fuse with me, I'll let your family go free.
Bill finally dropped Dipper. After roughly landing on the ground, Dipper got up on his knees and looked over at his family, who were all looking back at him nervously.
Bill – But they better make sure they don't get in my way again. After all, I can't promise something won't happen to them if they resist.
Dipper then stood up, facing away from Bill.
Dipper – And why would I agree to you? Especially after you broke your end of the last deal we made.
Bill – That's up to you, Pine Tree. But I wouldn't dawdle on this choice. The world won't wait that long.
Bill's eyeball showed a small vision of the earth splitting into two and exploding, making Dipper feel very nervous. He turned his gaze towards the ground as an expression of anxiety formed on his face.
Wendy – Don't listen to him, Dipper!
Soos – Yeah! He's probably lying again!
Stan – Come on, Kid!
Ford – Don't let him fool you, Dipper! Bill will say anything to stir up a bargain!
Bill – You keep quiet, Sixer! Let Pine Tree decide.
Mabel – Dipper! Don't listen to him! We'll figure something out!
Bill then seemed to smirk again as he glanced back at Dipper.
Bill – Think about it, Pine Tree. If you refuse, then you would be the one who allowed the end of the world to come to pass. Besides, you have a thirst for knowledge too, don't you? Fusing with an all-knowing gem like me would grant you all the knowledge that large head of yours desires. Just imagine what secrets and mysteries you would learn and uncover if your mind combined with mine.
Dipper looked back up at his family, with an unsure expression.
Bill – Come on, you know you have to say yes.
Everyone was looking fearfully at Dipper now, but Mabel's eyes were the most pleading of them all.
Mabel – Dipper, don't do it.
Dipper stared at his family for a while longer, and then he glanced around the town before he narrowed his eyes and closed them. After a small moment of silence, Dipper turned back to Bill and looked at him with a solemn expression as he held his hand out to the triangle-bodied gem. Bill's eye expression changed again to look as if he was smiling evilly. He then grabbed Dipper's hand and a blue flame erupted around the two hands, marking their deal. Mabel and the others were now staring disbelievingly and horrifyingly at Dipper and Bill, however Mabel looked the most devastated as she tried to run forward to stop her brother, only to have Ford and Wendy hold her back.
Mabel – NOOOOOOOOOO!
Dipper and Bill's gems began to glow as they performed their fusion dance. Bill then gave an evil glance to Mabel and the others before his and Dipper's bodies began to glow, merge, and reform. Their new body continued to grow bigger, and bigger, shocking everyone who was watching. Finally, the fusion's body took complete form and the glowing died down so that it was completely visible. The fusion looked like an enormous, much more evil form of Bipper, who had a now brass-yellow colored gem on his forehead, representing Dipper's gem, and another brass-yellow gem replacing his left eye, representing Bill's gem. He also had 5 extra arms that looked exactly like Bill's original arms alongside both sides of his body, resembling a centipede. The giant Bipper-fusion opened its eye, looked down, and smiled evilly at Mabel and the others, who all continued to stare at the new fusion in absolute fear and shock. He then began laughing evilly as he stood up and lifted his human hands into the air, which were both instantly consumed by large blue flames.
Pyrite – Yes, yes! I can feel it! The energy building within me faster than any I've ever encountered! Now the world really will be mine!
The Bipper-fusion continued to laugh, earning him plenty of horrified stares from everyone in Gravity Falls. Just then, sparkles of blue light seemed to shimmer around his left hand, which quickly formed into a cuff and a long chain, which seemed to connect to the rift in the sky. The Bipper-fusion looked at his left hand in surprise and shock as soon as the cuff and chain formed around it.
Pyrite – What?!
Sparkles of blue light then shimmered around the fusion's right hand and formed into another cuff and chain as well, surprising him even more.
Pyrite – What's happening…?!
More sparkles of blue light then began shimmering around the fusion's body, which quickly turned into a bunch of chains that wrapped around him, completely binding all his extra arms. Mabel and the others watched in shock and confusion as the Bipper-fusion was suddenly restrained and was currently trying to fight against the chains of energy that seemed to be trying to pull him towards the rift.
Pyrite (Bill) – What do you think you're doing?!
The fusion's expression then changed from confusion to one of determination, and his voice seemed to change as well, sounding a little more like Dipper's.
Pyrite (Dipper) – I'm done with standing by while you roam around and play people into your hands. Now this time, you've played into my hands! And I'm taking you back where you belong!
Two large arms made out of the same blue energy that was restraining the Bipper-fusion then grabbed his shoulders and began to pull him towards the rift. The fusion tried desperately to fight back, but his struggles appeared to be in vain. Mabel and the others ran forward, still in shock.
Mabel – That was Dipper's voice!
Stan – Is the kid doing this?!
Pyrite (Bill) – You can't be serious!
The others all turned their attention back to the Bipper-fusion, who seemed as if he was at war within himself.
Pyrite (Bill) – If you pull us back into the rift and seal it, you'll trap yourself on the other side as well!
Pyrite (Dipper) – Fine then!
Mabel and the others all gasped in shock and horror once they heard what both sides of the fusion just said.
Pyrite (Dipper) – If I have to end up imprisoning both of us together, I'll do it! After all, we made a deal, didn't we?! And this time I'm gonna make sure you keep your end of it!
The chains and the hands pulling the Bipper-fusion continued to pull him further and further towards the rift, no matter how hard he struggled.
Pyrite (Bill) – No…! No! You can't do this!
The fusion continued to try and break free, and his body then seemed to morph out of place just for a quick moment before it returned to normal, representing the fusion's instability. The Pines family continued to stare in horror, as the fusion was pulled closer to the rift.
Mabel – Dipper, no!
Mabel finally pulled free from Ford and Wendy's grasp and began running towards the Bipper-fusion.
Ford – Mabel, stop!
Wendy – Mabel!
Stan – Kid! Get back here!
Soos – Dude, wait!
Mabel continued to run towards the Bipper-fusion, but then she tripped and fell. The chains restraining the fusion finally began to pull him into the rift.
Pyrite (Dipper) – We're gonna stay in this decaying dimension, forever!
The Bipper-fusion was now almost completely pulled into the rift except for his head. He looked down one last second and saw Mabel looking up at him desperately, with tears beginning to spill from her eyes. The fusion's expression then turned sorrowful.
Pyrite (Dipper) – I'm sorry…
The Bipper-fusion made one last struggling jerk before he was pulled completely into the rift, which then began to grow smaller. As the rift shrank, all the corrupted gemstones of Bill's friends began to get sucked back up into it as well. Once they were all pulled in, the rift finally completely closed and disappeared. A large pink wave of energy then emitted from where the rift formerly was and spread all throughout Gravity Falls, reversing all the weird effects of Weirdmageddon and returning everything to how it formerly was before. The only proof of Weirdmageddon's occurrence left were the multiple merged gem shards lying everywhere. Everyone in Gravity Falls however, paid no heed to the changes around them, as their eyes were glued to the sky; none of them could get what they had just witnessed out of their heads. Even Gideon and his prison friends couldn't stop staring at the sky in shock and disbelief. Ghosteyes was the first to break the long silence.
Ghosteyes – That… was by far the bravest thing I've ever seen.
Gideon – It certainly was, Ghosteyes. I admit… It certainly was.
Gideon took off his hat and held it close to his chest as he continued to stare up at the sky. Wendy, Soos, Stan, and Ford were then all shown continuing to gaze up at the sky as well; sadness, shock, and disbelief beginning to fill each of their expressions.
Stan – What the heck just happened…?
Wendy – It was Dipper…
The others all turned to Wendy once she spoke, but her expression now only held sadness.
Wendy – He took control and used that chance to pull his and Bill's fusion back through the rift.
Ford – I see. Then that means Dipper fused with Bill intending to trap him back in the Nightmare Realm…
Soos then looked very upset.
Soos – But… but Dipper trapped himself there too. Then… then that means…
Stan – Are you saying that the kid is now stuck in the same messed up dimension that evil triangle gem came from?!
Wendy didn't say anything, but her expression gave everyone the answers they needed. Dipper was gone.
Soos – No… No, no, no, no! That can't be!
Stan then faced Ford, put both of his hands on his shoulders and looked him with an expression filled with desperation.
Stan – Ford! Come on! You know all about this gem stuff and how it works! Tell me that Wendy just hit her head too many times and doesn't know what she's talking about!
Stan looked at Ford strongly, his eyes pleading for him to say what he wanted him to say. Ford looked at his brother sadly before he looked down at the ground as tears began welling up in his eyes.
Ford – I'm sorry, Stanley… But I can't…
Stan's eyes widened for a moment before all the hope inside them died out and he covered his face with one hand, trying not to let the others see him break down.
Mabel – You're wrong…
Stan, Ford, Soos, and Wendy quickly turned their heads towards Mabel's direction once they heard her voice. She had finally gotten up onto her feet, but she didn't turn around.
Mabel – This is all just a horrible nightmare, right? And when I wake up, Dipper will be sleeping in his bed right across from me, right?!
Mabel finally turned around to face her family; she looked completely devastated. Tears were flowing heavily down her face and her expression held the same pleading desperation Stan's did. Wendy attempted to step forward.
Wendy – Mabel-
Mabel – I thought we won… I thought it was all over… I wanted to spend the rest of summer having fun with everyone and have the best birthday party ever.
Wendy and the others didn't dare to move another muscle, as Mabel's words made the pain in their hearts grow.
Mabel – But how can I do all that… without Dipper being right there with me?!
Mabel then fell to her knees and began sobbing uncontrollably.
Mabel – I don't care about the party anymore! I don't care that summer's almost over anymore! I don't even care about whatever I have to face or leave behind when I'm growing up! I just want my brother back!
Mabel continued to sob in despair until she felt a pair of arms wrap around her. Though her eyes were blurry from her tears, Mabel was slightly able to make out that it was Wendy who was hugging her.
Wendy – It's going to be okay.
Mabel – No, it's not… Not without Dipper.
Wendy continued to hug Mabel, trying to comfort her even though tears were also spilling from her eyes. Soos then walked over to his friends and hugged them as well; unable to hold back his own tears any longer. Stan and Ford watched the three for a while before they too joined in the hug. The five of them stayed that way for a while before they finally pulled apart. Mabel wiped her eyes with her arm and turned around to look back up at the sky once again, however something on the ground caught her eye; it was Dipper's hat, which had fallen off while he was dancing with Bill. Mabel quickly ran over to the hat until it was right at her feet and she stood still for a moment before she kneeled down and picked it up. She stared at the hat for another moment before she began to cry again and hugged it close to her heart, letting some of her tears drop onto the one piece of her brother she had left.
So, there you have it! I will post another chapter up soon!
If you like the idea so far, let me know if you'd like me to make an official plot, because I am truly considering it.
See you next time!
