So, I’m new at au’s, but I had a neat idea. I call it Gravity Gems.

What if gravity falls was all about gems (like from Steven universe). Not just having gf characters fill roles from Steven universe or recreate plots, but a whole new story of gems, both crystal and homeworld, starring dipper and Mabel as young half gems growing up on earth.



I’m sure plenty of people have done Steven Universe and Gravity Falls mashup au’s, but I think I have a different spin on this one.



So, dipper and Mabel’s mom was a permanent fusion (like garnet) that fell for a human man (you don’t know who yet). She gave up her form to have kids with him. Since she was a fusion, she had twins, dipper and Mabel. They live with Grunkle Stan (who used to fight alongside their mom and is a crystal gem too). Soos and Wendy can be young gems (Full gems). Soos can be a “defective” gem that was supposed to be a record keeper and data analyst gem, but never quite gained the ability to access and interpret it correctly. So, he was basically thrown out by Homeworld (but the handyman knows more than they think and will eventually be able to access all their secrets). He was just kinda wondering around earth lost and alone until Grunkle Stan found him and took him in. Wendy could be a kindergarten gem (Like Amethyst). She was “made” on earth nd that’s all she’s ever known. So she’s adjusted to earth life and fits in with humans better than most of the group. Even spending time with a group of local teens. She was the only one to know Dipper and Mabel’s mom. She was found not long before the final battle with Home World on earth from the gem war. She is the only one who knows Grunkle Stan’s secret that he used to be a crystal gem warrior. Grunkle Stan wants to protect the kids (including Soos and Wendy), so he doesn’t teach them gem fighting or tell them about Homeworld or anything about gems. He just says, “We’re aliens. We lived somewhere else, now we live here. End of story,” whenever someone asks about gem stuff.

I have way more that I came up with in the last hour since I came up with the au initially. So I’m doing a read more.







One day, Dipper finds a journal hidden in the woods. It once belonged to a crystal gem warrior and has details of gem fighting techniques, details about what gems are, tales of home world, wars fought over earth between crystal gems and home world gems, and details of all the powerful and wonderful things gems can do. All the stuff Grunkle Stan refuses to tell dipper and Mabel about since they’re “too young,” doesn’t tell Soos because he’s “won’t comprehend it,” and won’t tell Wendy because she’s “seen enough already.” So, Dipper, Mabel, Wendy, and Soos use the journal to start becoming gem warriors themselves.

Gideon is a kid who found one of these gem journals and a broken gem. He uses the info in the journal to harness some of the power from the broken gem. It gives him magical powers (Similar to the pendent from the real Gravity Falls). They stop Gideon and heal the broken gem. Out comes Pacifica. She is a young gem who was being groomed to be the next yellow diamond. Basically, she was home world royalty. The crystal gems stopped her and broke her gem, but the gem was lost before they could bubble it. She starts off villainous, hating humans and earth, seeking to destroy it all, but she believes these things only because that is all she’s ever been told. Dipper convinces her to give earth a shot and make her own decisions. So, she decides to spend time acting as a person in gravity falls until she makes up her mind whether or not to destroy it all. She then becomes a kinda friend to the young gems (And maybe love interest for Dipper depending on if you are into Dipcifica or not haha).

McGucket is discovered to be dipper and Mabel’s dad. He met their mom as a scientist studying alien anomalies in gravity falls. He found that the source was the gems. After the final battle for earth between the old crystal gems and Homeworld, he decided that gem stuff was too dangerous for a human to know about. So, he wiped his mind and that made him go crazy. So Grunkle Stan never tells the kids about him. Even though he doesn’t remember them, mcgucket has a strong bond with the kids and often follows them on their adventures

So, the new crystal gems fight monsters and solve mysteries around gravity falls Oregon, but never really travel farther than they can get by car. They don’t have a warp pad. The big twist is that Grunkle Stan has a gem brother (someone with the same type of gem, like how I think there are other pearls out there and stuff like that). He is trying to rebuild the warp pad that is under the shack to open a portal to home world. Stanley was taken during the brutal final battle for earth. The big bad (Yellow diamond I guess) has Stanford captured on home world as bait for the last crystal gems on earth (grunkle Stan, soos, Wendy, dipper and Mabel). So opening the portal for a rescue mission is incredibly dangerous and stupid, but of course Grunkle Stan loves things that are stupid and dangerous. Everyone finds out what Grunkle Stan is up to and tries to stop him from opening the warp pad, but he does and out steps the author of the journals, his brother.

Dipper’s gem is on his forehead. He is always a bit shy about his magical side and often tries to hide it from people he doesn’t know so he’ll look cool. That’s why he wears a hat, to cover his gem. This plays into how unsure of himself he is in the real show.

Mabel loves being a gem and proudly displayed her gem (which is on her belly). She makes sweater patterns based around a hole for her gem so she can always show it off the beat she can. She worries that she isn’t as powerful as Dipper, Wendy, and Soos so she compensates with more effort and jokes and better sweaters.

Wendy, I don’t know where her gem is, but her weapon has gotta be some sort of ax. She is very chill about being a gem, but that hides a lot of anxiety. She never lets her self-doubt show though. She relied a lot on Dipper and Mabel’s mother (She is the only one of the new Crystal Gems to have known their mom and Stanford and Mcgucket). She feels a bit lost without her and often acts rebellious and spends more time with the gem teenagers. She absolutely loves Dipper and Mabel like family (Sorry, Dipper. Friend-zoned), but there is a part of her that almost resents them for taking their mom away from her. Also, she definitely dislikes Mcgucket for not only taking Dipper and Mabel’s mom away, but for abandoning Dipper and Mabel and the gems (Even if he didn’t mean to completely break his mind and just wanted to erase the bad but leave the good, he still did it).

Soos’s gem is in his lower back. He hasn’t managed to figure out how to get his weapon out himself because he can’t reach his gem. He can get it out if someone helps push his hand to where it needs to go. As the series goes on, he starts to have flashes of Homeworld and the war. He starts to access info that he used to not be able to. The more crystal gem stuff they do, the more he can see, but he can’t control when or what he sees. This is the real reason Grunkle Stan never told him about gem stuff. He knew that exposure to gem stuff could unintentionally activate his Homeworld data logs, but with him being defective, Soos can’t control the flow of data. Grunkle Stan was worried this could break Soos’s mind. Luckily, it never breaks his mind, but it does allow a roaming gem to pick up on Soos’s signal.

Bill Cipher is a solo gem. He started as an experiment by homeworld. A forced fusion that went wrong. Now he is nearly omnipotent, but completely crazy. And his power are still limited by rules no one but Bill understands. Bill goes off and travels the universe solo to try and find a way to break his rules. His ultimate goal is ultimate power so he can return to Homeworld and rule it. He doesn’t particularly care about earth or humans, but Bill does care very much that Homeworld never destroys earth. Any other evil force can go ahead and blow it up, but, since Homeworld built Bill to destroy earth, he sees protecting earth from Homeworld as one big middle finger to them. Bill comes to earth to have some fun messing with the new crystal gems and to steal Stanford’s gem journals and soos’s mind. He thinks that the info in the journals mixed with all the info Soos can access should be enough for him to figure out how to break his rules.

Some quick timeline notes: Original Crystal Gems (The two Stans and Dipper/Mabel’s mom) defend earth from Homeworld in the war. Near the end of the war, they find Wendy. They think the war ends and Homeworld surrendered. Dipper/Mabel’s mom falls for McGucket. Dipper and Mabel are born (which means their mom gives up her physical form). Homeworld sends some new warriors. This is the real final battle with Homeworld. The Crystal gems fight them off and win, but Stanley is taken by Homeworld. Seeing the horrors of Homeworld and gem warfare, McGucket invents the mind gun. He didn’t mean to erase so much, just the worst of it, but he ends up breaking his mind. Soos is found and taken I by Grunkle Stan. Wendy agrees to keep the secret that they were gem warriors from Soos and the (then infant) Dipper and Mabel. She agrees without realizing that he will no longer train her either. Years later, Dipper finds one of Stanford’s gem journals. The new crystal gems are formed (Dipper, Mabel, Wendy, and Soos). They don’t tell Grunkle Stan. They train and fight monsters together. They stop Gideon and rescue Pacifica. Then they stop Pacifica. Grunkle Stan finds out they’ve been doing gem stuff and he admits that he used to be a gem warrior. He tells them that he won’t keep any more secrets from them if they stop with gem stuff. Both sides promise, but both sides are lying of course. Soos starts accessing Homeworld stuff. Bill comes. The new crystal gems discover Grunkle Stan’s secret warp pad. They think that means he is working for Homeworld and is trying to bring them here to destroy earth. Mabel trusts Grunkle Stan though and allows him to open the warp pad. Stanford returns!
