    The Mystery Shack 

Dipper Pines

A 12-year old boy hailing from Piedmont, California, and Mabel's twin brother. Spending time with his Great Uncle Stan (or "Grunkle") seemed like it was going to be one boring experience. But after he meets Steven Universe and the Crystal Gems, (as well as finding a mysterious journal) his vacation seems to have taken a more interesting turn.

  • Adaptational Angst Upgrade: A lot of the stuff in this fic pushes Dipper to a MUCH darker place compared with his show, particularly because he felt responsible for Lapis becoming Malachite. It also averts him forgiving Steven and Mabel for helping Stan bring Ford back, feeling that it was a betrayal of the trust that they had sworn to maintain after said incident, with him relenting after witnessing Steven's Break the Cutie moment as detailed below, and seeing just how much bad blood is between the Gems, Stan, and Ford, from all perspectives.
  • Adaptational Badass: Not at first, but he joins Connie for swordsmanship training under Pearl. For that matter, the fact that he begins his training while still recovering from the many physical injuries his body underwent in Sock Opera, and makes considerable progress despite still being in potentially debilitating pain and having previously refused aid from Steven's healing spit.
  • Adaptational Sexuality: Downplayed, but while he still has his canonical crush on Wendy, and is given an even stronger Ship Tease with Pacifica than he got in canon, Word of God has confirmed he's bi-curious, which is most noticeable with Stepper's second appearance.
  • Armor-Piercing Question: When Steven tries to convince him to let him erase his memories of Bill in “Society of The Blind Eye”, he asks Steven how doing so would make him any different than the Society.
  • The Blind Leading the Blind: Him and Steven helping Soos with finding a date.
  • Calling the Old Man Out: Dipper is usually the first to question the Gems whenever they're being mysterious or suspicious. Needless to say, this happens often.
  • Cool Sword: The Sword of Seasons, which can switch between Playing with Fire, An Ice Person, Shock and Awe, and Blow You Away modes.
  • Cloudcuckoolander's Minder: To both Mabel and Steven whenever their combined over-enthusiasm gets too out of hand.
  • Everyone Has Standards: Despite not being Peridot's biggest fan, he's the first to call Lapis out on her behaviour after she breaks the Tablet Peridot gave to her as a gift, due to knowing exactly how much it meant to Peridot.
  • Fat and Skinny: Is the Skinny while Steven is the Fat.
  • Foil: To Steven. Dipper is intellectual, cynical, introverted and prone to occasional selfishness. Steven, on the other hand, is emotional, idealistic, extroverted, and eternally selfless. However, both of them are extremely devoted to their friends and family and neither of them are willing to give up easily.
  • Heroic BSoD: At the end of "Sock Opera", everything from both the whose mess with Bill and the whole Malachite situation causes him to just break down crying on the floor of his room.
  • Innocently Insensitive: His excitement about discovering that the Gems are aliens gets the better of him in "Waterfall Gem", to the point that he nearly forgets that he should be focusing on trying to help Lapis.
  • It's All My Fault: Blames himself for Lapis becoming Malachite.
  • Limited Wardrobe: Because he’s so focused on other stuff that he rarely does laundry.
  • Locked Out of the Loop: Concerning many Gem-related things, and it drives him crazy.
  • Never Be Hurt Again: Dipper pushed himself so hard in "Do it for Them" partially because he wanted to avoid feeling as helpless as he did in "Sock Opera" again.
  • Not So Above It All: At the beginning of "Mirror Gem", Dipper initially doesn't find the mirror to be any real importance, even though Mabel and Steven are enamored with it. Even after it's revealed the mirror can "talk", he doesn't befriend it as easily as the two of them until it proves its worth to him by helping him embarrass Robbie in front of Wendy. By the time the gang decides to go show the mirror the Gems, he's as attached to the mirror as Steven and Mabel are:
    Dipper: You know, normally I wouldn't consider something like a mirror as a friend, but...
    Steven: Oh my gosh! Dipper! You warmed up to the mirror, didn't you?
    Dipper: Maybe... Just a little...
  • Not So Different: In "Out Too Far", he tells Malachite that, thanks to his experience as Stepper, he knows what it's like as part of an unstable fusion.
  • Official Couple: Eventually starts dating Pacifica.
  • Only Known By His Nickname: As in canon, but here both Steven and Lapis learn his real name ( Mason), though the readers don't.
  • Only Sane Man: Second only to Connie, he is often the one to ask the Gems questions that Steven won't.
  • Properly Paranoid: Dipper spent a large majority of the first two arcs of the story terrified at what might happen if the Gems ever discovered the journal. Turns out his worries were justified when the Gems find the journal and almost destroy it in "Gems and Journals".
  • Secret Keeper: While Dipper already keeps Journal 3 a relative secret during season 1, he's intent on keeping it hidden from the Gems in particular, lest they confiscate it from him due to the information it contains about them. When they eventually do discover it in "Gems and Journals", they ultimately decide to entrust it into his safekeeping.
  • Shell-Shocked Veteran: His reaction to Malachite has some shades of this, as does the aftermath of Bill possessing his body.
  • Straight Man and Wise Guy: The Straight Man to Steven's Wise Guy.
  • Tagalong Kid: Is this to the Gems along with Steven and Mabel.
  • Tears of Blood: As a consequence of Bill's possession in "Do it For Them".
  • Took a Level in Jerkass: Briefly in "Joy Ride" as a result of what happened with Malachite. He even suggests destroying Peridot’s escape pod despite not knowing (or caring) if she was in it or not.
    • He's so worried about Lapis that he is less than polite about Mabel and Steven being tired out from looking for her in "Chille Ted Part 1".
  • The Watson: He frequently poses questions concerning the Gems that Steven, with his trusting nature, would never think to ask.

Mabel Pines

Dipper's hyperactive and cheerful twin sister. Mabel makes the best of her time in Gravity Falls and almost instantly becomes friends with Steven.

  • Action Girl: Perhaps even more so than in the show. You don't wanna mess with Mabel when she's wielding her handy grappling hook.
  • Adaptational Angst Upgrade: Much like Dipper, she gets it here, as the story places greater focus on the consequences of her actions in GF and involvement with the more traumatic events of SU. Needless to say, she's just as much of wreck as Dipper and Steven are by the time Arc 6 begins.
  • Adaptational Nice Guy: She realizes how selfish she's being much faster than her canon counterpart and tries to do better more consistently.
  • Beauty, Brains, and Brawn: The Beauty to Dipper's Brains and Steven's Brawn.
  • Birds of a Feather: A platonic example. She and Steven get along with each other extraordinarily well thanks to their common interests and similar personalities.
  • Cannot Spit It Out: Is too afraid of ruining her friendship with Steven to tell him about her feelings for him. That she knows he and Connie like each other doesn't help much. She tried to confess in “Society of The Blind Eye”, to just get it out of the way, but fails.
  • The Cuckoolander Was Right: She's the one who suggests to Steven that he should use his healing powers to fix Lapis' broken Gem.
  • Freudian Slip: Accidentally lets slip to Wendy that she likes Steven in “Society of The Blind Eye” when listing her crushes.
  • Grappling-Hook Pistol: She uses it as a weapon even more in Universe Falls than in the show.
  • It's All My Fault: Blames herself for Dipper making a deal with Bill in "Sock Opera", especially when he starts hurting himself practicing swordfighting.
  • Likes Older Men: Once she gets over the initial shock, she's rather interested when she learns that Steven is 14.
  • Pink Is Feminine: She thinks Lion is adorable, and is more than happy to gain her own pink pet in Waddles.
  • Shipper on Deck: She's this for Steven and Connie.
    • She later starts shipping Peridot and Lapis.
    • She also starts shipping her brother and Pacifica.
  • Tagalong Kid: Is this to the Gems along with Steven and Dipper.

Stanley Pines

The head of the Mystery Shack, and Dipper and Mabel's great-uncle ("grunkle"). While he is generally extremely miserly and cynical to everyone, he can sometimes show a more pleasant side to the people he cares for.

  • Always Save the Girl: and other family members in this case, but he maintains this mindset from canon. Just like in canon, Ford is furious for this trait of Stan, but it's taken a step further when Stan considers Ford and Rose's The Needs of the Many approach to be self-righteous.
  • Big Damn Heroes: Stan highhandedly comes to both Dipper and Mabel's rescue in "Waterfall Gem" by saving them both from nearly dying at the hands of their water clones.
  • Benevolent Boss: In a surprising revelation, he gave Greg a loan in order to buy a car wash despite his normally greedy nature.
  • Everyone Has Standards: Stan isn't the most honest person around, but as "Like A Comet" demonstrates, even he thinks Marty was a money-grubbing sleazebag. He actually lampshades this when Dipper wonders if Greg is being a bit harsh with his description of Marty.
    • On the other end of the spectrum, while Ford still considers Stan to be a scoundrel, even he thinks that Stan wouldn't go as far as to wipe the Crystal Gems' memories.
  • Fastball Special: Has Amethyst launch him to save the kids in "The Stanchurian Candidate".
  • Gold Digger: Not directly, but in "Mismatched Making" Stan goes from mocking the idea of Dipper getting a girlfriend to suddenly be eager to help when he finds out Dipper has a developing relationship with the richest girl in town. As if it leads to something more in the future then it means he'll have a rich nephew to mooch off of.
  • Made of Iron: Downplayed in "Waterfall Gem", when he takes a beating from the water clones and injures his back. Still, he manages to get up even despite it to rescue the twins.
  • Sitcom Archnemesis: Seems to view the Gems as this to a degree, due to the Temple's statue "stealing tourists away." Amethyst appears to be the exception to this.
  • Interspecies Friendship: With Amethyst. It also doubles as an Odd Friendship, considering how Stan feels towards Garnet and Pearl.
  • Jerkass Has a Point: Is usually a bit rude when doing so, but occasionally makes good points.
  • Jerk with a Heart of Gold: He already is this in canon, but his rather touching friendship with Amethyst demonstrates this even more. Especially when you consider just how similar the two of them are.
  • Not So Different:
    • Him and Pearl, of all people. Despite the fact that they can't stand each other, both of them were deeply attached to someone (Ford for Stan and Rose for Pearl), only to have that person suddenly ripped from them in situations they were helpless to prevent. As a result, they are both left rather bitter, towards each other and the world around them, and deal with their pain with rather unhealthy methods.
    • Interestingly, this makes him similar to Blue Diamond as well, but while she is completely Locked Out of the Loop about what happened to Pink Diamond, Stan is the only one who knows what happened to Ford.
    • Him and Rose as well. They both faked their deaths and assumed another identity, they are both fiercely protective of their loved ones, they both lied to their loved ones about who they really are, they were both once close to Ford prior to having a falling out with him, they both made some pretty callous decisions, and they both have been subjected to Broken Pedestal moments.
    • He and Amtheyst consolidate a bit more in "To Con a Clod" after Peridot reveals how Amethyst is "defective", since he's used to being a screw-up himself.
  • Not So Stoic: He acts like he doesn't care much for Steven, but it's clear he has a soft spot for him. He even tells Ford not treat him as a Replacement Goldfish for Rose, and tells him that he's not responsible for his mother's actions when Steven apologizes to him in "Cry For Help".
  • Papa Wolf: In "Waterfall Gem", Stan squares off against three of Lapis' water clones alone in order to protect the kids. Even when he's defeated and the kids get involved anyway, he pushes through a back injury to save Dipper and Mabel from them.
  • Took a Level in Badass: Stan squares off against three of the water clones in "Waterfall Gem", complete with his iconic brass knuckles.
  • Unwanted Assistance: He ends up making the crack in Amethyst's gem even worse in "An Indirect Kiss" while ironically trying to fix it.

Wendy Corduroy

One of the workers at the Mystery Shack, who has taken the position as a job over her summer break. While she is generally very lazy at work, she has a large circle of friends, and is more than capable of doing things if she's motivated.

  • Adaptation Origin Connection: Apparently, Kevin was one of the boys she used to date back in the day.
  • Cool Big Sis: She's already this in the show, but she demonstrates this trait even moreso in An Indirect Kiss by encouraging Steven about using his healing powers.
  • It Amused Me: In "Log Date: 7 15 2", when Peridot assumes that slang terms like "rad" and "dude" are some kind of "human code", Wendy agrees to teach her the "code" in exchange for a peek at the drill largely because she feels that it's going to be hilarious.
  • Missing Mom: Word of God is that this will become a bonding point between her and Steven.
  • Only Sane Woman: In "An Indirect Kiss", she tries to dissuade Steven from trying to bring about his healing tears through causing himself pain, even if Soos is on board with it.
    Wendy: O-ok there. Maybe we should come up with another idea, preferably one that involves less glass.
  • Secret Keeper: As of “Society of The Blind Eye”, she knows about Mabel’s crush on Steven.

Jesus "Soos" Ramirez

Stan's right-hand man, the oldest staff member of the Mystery Shack besides Stan himself, and the handyman.

  • Action Survivor: Him and Greg somehow escape the van being launched into the air by the water clones unscathed in "Waterfall Gem".
  • Friend to All Children: He gets along just as good with Steven as he does Dipper and Mabel.
  • Mundane Object Amazement: At the beginning of "Mirror Gem" he finds an empty pie tin and is completely fascinated by it.

The Author, Stanford Pines

The mysterious author of the journals. He disappeared thirty years ago, leaving his journals and a plethora of enigmatic secrets behind. He returns to his dimension at the end of Arc 5.

  • Abusive Parents: It's made more explicit that Filbrick saw Ford as a Meal Ticket, and Ford was glad to be free of the bastard.
  • Adaptational Nice Guy: While still overall depicted as a gruff, bitter man in his debut, in Gravity Falls canon, Ford was never seen defending Stan from Filbrick's disowning, and stood off to the sidelines. Here, he attempted to come to his brother's defense, only to be threatened with the same eviction. The third-person narration even reveals that he did regret what happened that day, occasionally wondering how things could've been different during his college years. His interactions with the Gems also gave his social skills a boost, as he managed to become great friends with them. Still didn't stop the end result of him being thrown into dimensions, but still. In regards to the story of Universe Falls as a whole, he's presented in a much more amiable and heroic manner than in canon, being more willing to converse/socialize with the other characters, and displaying much more regret for his past mistakes, along with his efforts to make up for them.
  • Asexuality: Jenn writes Ford as being ace. Best seen during Fiddleford's first meeting/adventure with Ford and the Gems, where he outright admits to finding romance more baffling than his usual mysteries, which Fiddleford and Garnet disagree with.
  • Berserk Button: Like Pearl, do not insult Rose where he can hear it.
  • Birds of a Feather: Platonic example, his and Rose’s shared fascination with the weirdness in Gravity Falls made them fast friends.
    • Once Pearl stopped thinking that he was going to try and steal Rose away from her, they actually bonded over their shared liking of D, D, and More D.
  • But for Me, It Was Tuesday: Has been to so many exotic extradimensional locales that the moon is actually rather underwhelming for him.
  • Good Is Not Nice: Though it's doubtful he'd actually go through with it, he actually threatens Peridot with shattering to try and get her to talk about the Cluster.
  • Knight of Cerebus: Just like before in Gravity Falls canon. Ford's on the side of good...but his introduction and the lead-up to it creates an enormous amount of tension within the other characters' dynamics at the end of Arc 5...and Arc 6 starts off on a very tense note as a result.
  • The Needs of the Many: A carryover from canon, though he makes it more explicit to Stan here, who thoroughly disagrees with this mindset.
  • No Social Skills: Not as much in the present as in canon thanks to his friendship with the Gems, but back during his initial research into Gravity Falls, he had a tendency to ask Rose very personal questions about Homeworld without realizing why it bothered her, which Fiddleford quickly caught onto.
  • Not So Different: When Peridot mentions not being able to return to Homeworld in "In Too Deep", Ford wonders if he'll ever see his old hometown again.
  • Parting Words Regret: He and Rose had an argument over the potential danger of the portal, and while he still trusted Rose enough to hide Journal #3 for him, he never fully repaired their friendship and is devastated to hear that Rose is gone.
  • Pet the Dog: Attempted to come to Stan's defense when Filbrick disowned him, but was threatened with the same punishment and forced to back away.
  • Suspiciously Specific Denial: About the Gem ship below Gravity Falls, designated as Crash Site Omega.

    The Crystal Gems 

Steven Universe

The sole male member of the Crystal Gems and son of Rose Quartz. He always wants to see the best in others and join the other Gems in their missions.

  • 100% Adoration Rating: Somewhat subverted. While most of the people of Gravity Falls like him, Gideon loathes him for supposedly stealing Mabel's affections away from him.
  • All-Loving Hero: Even to people who regularly show him disdain, like Stan or Gideon, Steven is still always pleasant and kind. He and his father are also the only people to call Old Man McGucket "Mr." McGucket.
  • Already Met Everyone: In contrast to Mabel and Dipper, he knows most of the people in Gravity Falls already.
  • Birds of a Feather: With Mabel.
  • Break the Cutie: Suffers this at the start of Arc 6, where after learning that his mother erased the memories of the Crystal Gems, the more traumatic parts of Arc 5 finally sink in and he tightly hugs Dipper while crying.
  • Fanboy: Of the Mystery Shack and all its attractions. Stan practically has to force him to leave!
  • Fat and Skinny: The fat one to Dipper's Skinny.
  • Foil: To Dipper. Both are big-time Determinator, but even so, their personalities and ideologies are almost exact opposites. Still, that hardly affects their good friendship.
  • Horrible Judge of Character: He thinks Stan giving him a half-eaten candy bar is a sign of kindness when really it's just to get him to leave the Mystery Shack.
  • I Just Want to Be Special: At least as special as his mom was.
  • Intergenerational Friendship: With Soos and Wendy.
  • In Touch with His Feminine Side: He gets excited about all things cute and pink just as much as Mabel does.
  • It's All My Fault: In "Cry For Help" he blames himself for Rose's actions and apologizes to Stan, who thankfully sets him straight.
  • Keeping Secrets Sucks: Steven is none too fond of the idea of keeping Journal 3 and its contents a secret from the Gems, but he begrudgingly does so as per Dipper's request.
  • Locked Out of the Loop: The Gems don't tell Steven a lot and compared to his relative complacency about this in the show, he's much more bothered by it here.
  • Nice Job Breaking It, Hero!: While his plan to reconcile Pearl and Greg goes ofg without a hitch, not only do the Stan twins not reconcile, but they wind up driving a wedge between Dipper and Mable by getting them to question their relationship.
  • Older Than They Look: Word of God is that he's already 13 at the start of the story, but he looks younger than Dipper, Mabel, or Connie.
    • Like in canon, he turns 14 in "The Answer". flabbergasting Dipper and Mabel as well as Connie.
  • Status Quo Is God: Steven seems to be rather uncomfortable about shaking up his warm, familial relationship with the Gems by questioning their authority, even if they are keeping quite a few secrets from him.
  • Straight Man and Wise Guy: The Wise Guy to Dipper's Straight Man.
  • Superior Successor: Stan views him as better than Rose ever was.
  • Tagalong Kid: To the Gems along with Dipper and Mabel.
  • The Thing That Would Not Leave: Because Steven visits the Mystery Shack on a daily basis, he's this to Stan.


The leader of the Crystal Gems, and the calmest. Generally seen as the person that took over after the loss of Rose Quartz.

  • Big Damn Heroes: In "Arcade Mania", she rescues Dipper from the final blow from Rumble Mc Skirmish, then proceeds to beat the shit out of him.
  • The Comically Serious: Perhaps even more here than in the show.
  • It Amused Me: She let Stan go ahead with his hot air balloon plan in "Joy Ride" because she knew nobody would get hurt, and that it would be hilarious.
  • Multiple Head Case: Her corrupted form in "Monster Falls" has a Ruby head and a Sapphire head.
  • O.O.C. Is Serious Business: One of the unofficial rules for writing Garnet's dialogue in the series proper is that she never asks questions (presumably because she has most answers already via future vision). However, due to her Laser-Guided Amnesia she has plenty of questions for Old Man McGucket in "Society of the Blind Eye".
  • The Reliable One: Makes cookies during "Li'l Gideon", and gives Mabel advice on ending things with Gideon when she doesn't know how to stop going out with him.
  • Tempting Fate: When Amethyst asks what the odds are of Gideon breaking out of jail after he's arrested, Garnet replies that it's "not likely." Even discounting Weirdmageddon, it's been hinted by Jenn that Gideon may break out in the future and cause trouble.


The youngest member of the main Crystal Gems. She is best described as rowdy and fun-loving. As well as a Foil to Pearl.

  • Birds of a Feather: Her and Stan.
  • Cool Big Sis: Amethyst is generally less responsible than Garnet and Pearl, especially when doling out advice. An example of this is when she tells Dipper about the size changing crystals in "Measure Up", knowing full well how dangerous they can be.
  • Kleptomaniac Hero: It's been implied that she and Stan used to partake in breaking and entering together "for kicks".
  • Odd Friendship: She seems to get along quite well with Stan; despite the former's resentment towards the Gems. This is also an Interspecies Friendship.
  • O.O.C. Is Serious Business: Stan finds it worrying when she doesn't come to complain to him about Sardonyx in "Cry For Help".
  • Platonic Life-Partners: Her friendship with Stan is this.
  • The Prankster: After telling Dipper about the size changing crystals, she asks him to bring her back a few so she can use them to pull pranks.
  • Voluntary Shapeshifting: She does this quite a bit and often for humorous reasons, such as helping Stan scare away trick-or-treaters in "Summerween".


The strategist and brains of the Crystal Gems. She is very organized and motherly towards Steven and occasionally the twins.

  • Adaptational Angst Upgrade: In addition to the situation with Lion as in the series, Pearl is angst over the fact that Rose and the Author were very close. Which makes her reaction more understandable here.
  • Berserk Button: The idea that the journal contains private information about Rose infuriates her even more than the information that it contains about her, Garnet, and Amethyst.
    • In "Future Vision", it's shown she doesn't like the idea of someone keeping someone else as a slave against their will.
    • As shown in "Rose's Scabbard", never ever insult Rose in her presence.
  • Birds of a Feather: She and Dipper bond over their natural affinity towards science and mathematics, him being the only one who is able to help her in building their spaceship in any meaningful way.
    • Once Pearl stopped thinking that Ford was going to try and steal Rose away from her, they actually bonded over their shared liking of D, D, and More D.
  • Closet Geek: It turns out that Pearl's extensive knowledge of strategy and military experience makes her the ideal Dungeons, Dungeons & More Dungeons player.
  • Condescending Compassion: Several of her interactions with the twins come across as this.
  • Defrosting Ice Queen: Especially towards the twins. Throughout arc 1 and several parts of arc 2, Pearl is occasionally aloof awkward around them, but as time goes on, she really warms up to them, to the point that she's constantly fretting over their safety in "An Indirect Kiss".
  • Gamer Chick: Likes D, D, and More D, and is fairly good at it.
  • Heroic Willpower: Managed to resist Bill's control in the past, even trying to shatter herself to stop Bill from using her to harm Rose. Not even Garnet resisted as well as she did.
  • My Beloved Smother: She acts like this towards both Steven and the twins, quite frequently.
    Pearl: (hugging the kids) Steven! Dipper! Mabel! Are you three alright?
    Pearl: O-oh, yes! Of course!
  • Noble Bigot: Her condescending attitude towards humans is clearer here since she gets to interact with them more regularly. Still, its often Played for Laughs, like her grim conclusion in the bottomless pit:
    Pearl: Gems have much longer lifespans than humans. Plus, even though we don't need to eat, you humans do, which means you all will only be able to last in here for a few days at the most.
  • Not So Different: Her and Stan, of all people. Despite the fact that they can't stand each other, both of them were deeply attached to someone (Ford for Stan and Rose for Pearl), only to have that person suddenly ripped from them in situations they were helpless to prevent. As a result, they are both left rather bitter, towards each other and the world around them, and deal with their pain with rather unhealthy methods.
  • Nervous Wreck
  • Not So Stoic: Downplayed: when Gideon used his amulet to involuntarily make the audience, including the Gems, stand up and dance, Pearl was clearly caught off guard.
  • Underestimating Badassery:
    • In "Magic and Mystery", she apologizes to the kids for underestimating their ability to find both of the light canons after they successfully bring them both back and save the day just in time.
    • In "An Indirect Kiss", Garnet advises her not to underestimate Dipper and Mabel, as she "knows better than to underestimate humans by now".

Rose Quartz/Pink Diamond

Steven's mother, and the founder and original leader of the Crystal Gems, Rose Quartz passed away 13-14 years before the story began giving birth to Steven. She is actually Pink Diamond, who faked her shattering and assumed the identity of Rose Quartz permanently.

  • 100% Adoration Rating: Subverted. Most people loved her, but Stan implies that he really didn't back when she was alive:
    Stan: Back when she was around, me and your mom were never on good terms.
    • This is because she wouldn't help him get Ford back.
  • Birds of a Feather: Platonic version, she and Ford quickly bond over their shared fascination with Gravity Falls' secrets. Even after their fight, it says a lot that Ford entrusted Journal #3 to her.
  • Broken Pedestal: To the other Crystal Gems in "Lost and Found" after it's revealed she erased their memories.
  • Everyone Has Standards: Even she couldn't stand how stuck-up unicorns are. In addition to their general obnoxiousness, they probably reminded her too much of her fellow Diamonds and other Homeworld gems.
  • Friend to All Children: She's very nice to Dipper during their accidental encounter in "Lion and Waddles".
  • Friend to All Living Things: As shown in her brief interactions with Lion in "Lion and Waddles".
  • It's All My Fault: Often blamed herself for Ford getting sucked into the portal.
  • Mysterious Past: The unknown details behind her apparent history with the author make Rose even more of an enigma in the present day. It's also been hinted that she's encountered Bill before, and that they did not part on good terms.
    • Also, she seems to have used the Memory Gun used by the Society of the Blind Eye on the other Crystal Gems, removing their memories of the author, and potentially several other events, for unknown reasons.
    • Even after the above is further explained, the history and supposed deal she had with Bill are still a mystery.
  • Not So Different: Her and Stan. They both faked their deaths and assumed another identity, they are both fiercely protective of their loved ones, they both lied to their loved ones about who they really are, they were both once close to Ford prior to having a falling out with him, they both made some pretty callous decisions, and they both have been subjected to Broken Pedestal moments.
  • O.O.C. Is Serious Business: Ford finds her farewell letter to be unusually cryptic, even accounting for the code hidden in it
  • I Choose to Stay: Not only did Rose decide to stay on Earth, she also decided to settle down in Gravity Falls so she could figure out why it was such a supernatural hotspot.
  • Parting Words Regret: Regretted her argument with Ford, and apologized posthumously in a letter she left with Greg before she gave birth to Steven.
  • Posthumous Character
  • Shadow Archetype: She is this to Dipper, who would've become just like her had he let his Dude, Where's My Respect? mentality get the better of him, came to believe his family didn't care about him, and ran away.
  • Two Aliases, One Character: Like in the show, she's actually Pink Diamond.
  • Well-Intentioned Extremist: It's implied that the reasoning for her erasing the memories of the other Gems to protect them.
    • It's revealed in "Chille Tid, Part 2" that the erasure was part of a desperate attempt to heal them from what Bill Cipher did to them when he tricked them into letting him possess them.



The fusion of Amethyst and Pearl.


The fusion of Garnet and Amethyst.


The fusion of Garnet, Pearl, and Amethyst.

  • Early-Bird Cameo: She appears in "Gideon Rises" after Gideon takes off after Dipper and Mabel in his Gideon-bot.
  • Fandom Nod: Steven says during "Dinner Shack" that she works as an apple-picker.


The fusion of Steven and Connie, first seen in "Alone Together".

  • Ambiguous Gender: Much like in the show, Stevonnie is referred to by "they/them" pronouns in Universe Falls.
  • Living Emotional Crutch: In their debut chapter, the twins serve as this for Stevonnie. They help keep the fusion grounded and remind them that they are still two halves of one whole. It's for that reason that Stevonnie insists that Dipper and Mabel accompany them to the party in the warehouse, even if its a "teens only" party and they can't follow them inside. At the party itself, Wendy serves as one for them too, giving them someone to talk to and hang out with, at least until they're eventually separated from her.

"The awesomely magical, always lovable Maven!"

The fusion of Steven and Mabel, first seen in "Together Forever". Cheerful and enthusiastic, they embody the close friendship between the two, though because of this, they can be quite reluctant to split apart.

  • Ambiguous Gender: Much like Stevonnie, Maven's gender is unclear as they are a fusion between Steven and Mabel. Hence, they go by "they/them" in the story.
  • Break the Cutie: Maven spends most of their debut chapter bright and happy, but by the end, they're a distraught, emotional mess. Torn between splitting up for the sake of salvaging their fading personalities and maintaining their fusion, its no wonder that Maven eventually ends up breaking down and sobbing into Garnet's arms after she comes to find them.
  • Cloud Cuckoolander: And then some. Its sort of a given seeing as how they're a fusion of Mabel and Steven.
  • Cute Clumsy Girl: Has a tendency to trip or bump into things due to not paying attention.
  • Did You Just Flip Off Cthulhu?: Calls Pyrite "useless".
  • Extra Eyes: Maven has four eyes.
  • Fatal Flaw: Maven is very self-centric, to the point that they find it very hard to empathize with the feelings of others. This can be seen by how they completely misunderstand why Dipper and Connie are so desperate for them to unfuse, lest they lose touch with the respective halves of their personality.
  • Foil: To Sugilite. Both fusions enjoy existing as such, but they both also have a tenancy to get a bit out of control with it, to the point where they refuse to split up. However, unlike Sugilite, Maven is able to see the potentially disastrous results of what remaining fused for the rest of their life could invoke, and so they unfuse willingly, as opposed to having to be forcibly split apart.
  • Fun Personified: Maven is described as the embodiment of Steven and Mabel's friendship, as well as they fun they have together.
  • Hope Bringer: Helps the Gems get back in the game during the Pyrite fight.
  • Improbable Weapon User: With some focus, they end up creating a Grappling Shield.
  • It's All About Me: While fused, Steven and Mabel are continually distracted by each other and their shared excitement, and as a result, Maven comes across as innocently self-centered, to the point of near-narcissism in some instances.
  • Large Ham: They're very expressive and loud, personality traits that everyone they encounter easily notices.
  • Meaningful Name: More than just being a cross between Steven and Mabel's names, "Maven" is another word for an enthusiastic expert or connoisseur or something (i.e: a "fahsion maven"). So in a sense, Maven could be described as a maven when it comes to maintaining a healthy fusion (to an almost unhealthy degree).
  • Mental Fusion: The longer they're fused, the greater the risk Maven puts themselves in for losing touch with the respective halves of their personality (Steven and Mabel), which, as Garnet warns them, could ultimately disappear into their fusion forever if they're not careful (very similar to what nearly happened to Sugilite in Strong in the Real Way).
  • Morphic Resonance: They certainly look like a mashup of Steven and Mabel, with Steven's gem, sandals, curly hair, and two of his eyes. Mabel brings the sweater, skirt, braces, hair length, and other eyes.
  • Portmanteau: "Maven" is essentially the result of mashing Mabel and Steven's names togther.
    • They initially considered "Stabel" but decided against it after feeling it "sounded better in their head."
  • Pronoun Trouble: As the mental aspects of their fusion progress, they eventually start referring to themselves as "I" instead of "We." They likewise eventually start referring to Steven and Mabel as "they" instead of "we."
  • Verbal Tic: Due to being a fusion of his niece and an unrelated child, they address Stan as "Grunkle Pines" or "Mr. Stan."

"But if you care so much about names, like some people do, then I guess you can just call me Stepper."

The fusion of Steven and Dipper, first introduced in "Forever Alone". He's initially unstable, being the merging of two drastically different personalities, but by the end of his debut chapter, he gains both harmony and confidence after the boys reconcile.

  • All Work vs. All Play: In his debut chapter, Stepper constantly switches back and forth between excitably enjoying the experience (Steven) and trying to take finding the harmony between them seriously for the sake of curtailing it as soon as possible (Dipper). Needless to say that these conflicting mentality between his two halves causes the fusion more than his fair share of problems.
  • Ambiguous Gender: Rarely enough, averted. Stepper is a rarity in that he's the only fully male fusion in Universe Falls, being composed of two males instead of two females (like Opal or Sugilite) or a male and a female (like Stevonnie or Maven).
  • Badass Boast: His confident banter while fighting off Peridot's robinoids (partially quoted in the caption above) is not only awesome, its also a heartwarming reflection of how Steven and Dipper were able to harmonize and reform to rescue Mabel and the Gems in the nick of time.
  • Big Damn Heroes: After harmoniously reforming near the end of the chapter, Stepper rushes into battle against Peridot's robinoids, using his shield journal to easily rescue Mabel and the Gems from their clutches.
  • Bishōnen: He's described as having boyish features but he's also called "handsome" by Mabel. His looks are apparently enough to get even Wendy to momentarily drool over him (that is, until she finds out who he's made of).
  • Centipede's Dilemma: Can apparently levitate fine as long as he's not aware of it.
  • Foil / Good Counterpart: To Malachite. Both characters are unstable fusions representing unhealthy relationships, but while Malachite was outright toxic, Stepper is the result of a well-meaning extrovert trying to get a chronic introvert to open up. While this initially has Dipper feeling like he's being trapped in something he doesn't want to do, he eventually realizes Steven was right about his tendency to shut himself out from others while Steven acknowledges he was being way too forceful in the matter. This ability to acknowledge unhealthy issues allows them to finally stabilize, unlike Malachite, who was created from mutual malice.
    • In "Out Too Far", Dipper even brings this up In-Universe as a reason that they're Not So Different.
    • He's also a foil to Maven (which is fitting, since their non-Steven components are already foils to each other). Maven was extremely enthusiastic about fusing, to the point where they didn't want to de-fuse at first and almost lost their individual identities during the fusion. Stepper, on the other hand, was an unstable fusion who wanted to de-fuse as quickly as possible, and both halves of him suffered for it, but learned to appreciate it (albeit maintaining a healthy sense of identity once he did embrace his existence).
  • Funny Schizophrenia: Zig-Zagged. Due to having far more clashing personalities than Stevonnie or Maven, Stepper's attitude conspicuously switches between Steven's and Dipper's every other line, making him seem like an almost Gollum-esque Mood-Swinger. It's Played for Laughs at first, but as Dipper's frustration and discomfort with being fused mount, it becomes Played for Drama instead.
  • Genius Bruiser: Seen in his battle against Peridot's robinoids, Stepper is very clever and quick to the punch in a fight. It only makes sense that he would be of course, given Dipper's intelligence and Steven's strength.
  • Gravity Is a Harsh Mistress: Ends up forming in midair while at the barn, only to crash when he realizes that he's levitating.
  • Humanoid Abomination: Or at least Peridot seems to think so. Though Stan also hints towards this, claiming that Stepper would make a good attraction at the Mystery Shack due to his extra set of arms.
  • Mind Hive: During their initial time fusing, Steven and Dipper's conflicting personalities refuse to easily mix, resulting in Stepper constantly switching back and forth between the two and not gaining a "voice" of his own until the end of the chapter.
  • Morphic Resonance: Stepper is physically described as an even mix between Steven (where his gem, shirt, pants, sandals, curly hair, and one set of arms come from) and Dipper (where is hat, vest, hair color, and other set of arms originate). His lean build is even a compromise between Steven's stockiness and Dipper's skinniness.
  • Motor Mouth: When Stepper stabilizes and returns in Three's A Crowd, he drops his Funny Schizophrenia, but still tends to ramble in an attempt to speak in overly precise terms.
  • Multi-Armed and Dangerous: Stepper has an extra set of arms below his usual pair.
  • Opposites Attract: Subverted. Dipper and Steven have incredibly different personalities, and much of the duration of their time fused together demonstrates just how different those personalities are. However, after meeting each other half way and finding a compromise between them, their second time fusing into Stepper creates a much better experience for them both, allowing them to finally "find the harmony" and enjoy their time together as a fusion.
  • Portmanteau: His name (thought up by Mabel after several duds) is a mix of Steven and Dipper.
  • Spell Book: Stepper's weapon is a magical version of journal 3 that is half-filled with information all about Dipper, while the other half is entirely about Steven. The center page allows Stepper to conjure smaller, weaponized versions of Steven's shield. Word of God is that this so-called "shield journal" has other abilities that will be revealed in future chapters.
  • Talking to Themself: Stepper does this a lot. Mostly as a sign of his general instability as a fusion. His bouts of "one-sided banter" can essentially be viewed as conversations (or rather, arguments) between Steven and Dipper, even if, to the outsider looking in, he'd likely look almost insane for doing so.
  • Telepathy: Stepper seems to have a very odd form of this, where one half of him can briefly tap into what the other one is thinking. This is visually signified by both his gemstone and his birthmark briefly flashing.
  • Throwing Your Shield Always Works: Stepper's entire fighting style is based around tossing smaller, sharper versions of Steven's shield conjured from his shield journal.
  • Verbal Tic: Much like Maven, he switches back and forth between calling Stan "Mr. Stan" and "Grunkle Pines".

"What do you get when you take a dashing, well-dressed dream demon and a genius, technologically inclined upstart Gem and fuse 'em both together? Well, I'll tell ya what you get! The one, the only, all-powerful, unstoppable PYRITE!"

A fusion between Peridot and Bill Cipher.

  • Ax-Crazy: What else can you say about a fusion with BILL CIPHER as one of its components?
  • Ambiguous Gender: While Peridot comes from a species that are non-binary but refer to themselves as female, Bill Cipher comes from a place with literally billions of genders, and which requires paperwork to determine orientation. And he hasn't been keeping track of his.
  • Beyond the Impossible: Their whole existence, as Gems supposedly could only fuse with other Gems before Steven came along, and Bill Cipher is most certainly not a Gem. Lampshaded by Pearl soon after their introduction.
    Pearl: I-its... its not possible! H-how could they even fuse in the first place!? Bill isn't even a-
    Pyrite: It's called making the most of a golden opportunity, Bird Brain!
  • Cane Fu: They use their cane to fight just as much as they use Peridot's powers.
  • Classy Cane: One which they got from their Bill half.
  • Clipped-Wing Angel: The fully-Bill-controlled Pyrite counts as this, as they don't fare much better than Pyrite did before.
  • Curb-Stomp Battle: They dish this out against the Crystal Gems, but the tables are quickly turned once Maven and the other fusions enter the scene.
  • Evil Overlooker: In the Arc 7 cover.
  • Flight: Courtesy of Bill, the fusion can fly on its own.
  • Godzilla Threshold: The Crystal Gems don't typically fuse together unless things get really dire. Bill and Peridot fusing together proves to be just that big of a problem to force them to pull most of their fusions, Opal, Sugilite, and Sardonyx (with Alexandrite not in the running only because she was too big to fit on the Galaxy Warp), in order to win! Lampshaded by Maven:
    Maven: This is literally Bill and Peridot working together. How is it not super serious?
  • Humanoid Abomination: Part Gem, part whatever Cipher is sure qualifies.
  • Large Ham: The quote above shows that they have a hammy side.
  • Meaningful Name: As Sardonyx notes, pyrite is more commonly known as "fool's gold," and that's what all of Bill's promises to Peridot to get her revenge on the Crystal Gems and back to Homeworld with their fusion end up being.
  • Multi-Armed and Dangerous: They have four arms: Two at their shoulders which are clearly Peridots, and two on the side of their stomach, which are stylized after Bill's arms.
  • The Nicknamer: Inherited from Bill, naturally; They don't call anybody by their actual name, and instead use their previously established nicknames (Fuse Box for Garnet, Shooting Star for Mabel, etc).
  • Non-Human Humanoid Hybrid: Half-Gem, Half-Whatever-Bill-Is-Supposed-To-Be. Although, admittedly, they're only superficially humanoid.
  • Outside-Context Problem: Before Pyrite made their debut, most of the story was dealt with taking care of threats that belonged to either the Steven Universe world, or the Gravity Falls world. Sure, the two would connect since the universe is shared now, but they were still explicitly from one universe or the other. With Pyrite, they're literally a fusion between two characters from different universes, something that was never even hinted at to be possible before.
  • Playing with Fire: Thanks to Bill's half, Pyrite is capable of casting fireballs, which are green.
  • Talking to Themself: They start doing this as it becomes clear they're about to lose and the Crystal Gems present them with a Morton's Fork Sadistic Choice.
  • Technicolor Fire: Green.
  • Third Eye: Bill's eye functions as one aesthetically. Bonus point for it being located right above their forehead, which is the usual spot for the third eye.
  • Villain Override: Near the end of the fight, Bill briefly takes full control of the fusion, an experience that Peridot does not seem to like.
  • Voice of the Legion: Their voice is a mix of Bill and Peridot's voices speaking at once. When Bill takes full control, Peridot's voice effectively disappears.

    Youth of Gravity Falls 

Connie Mahaeswaran

A young girl in Gravity Falls and Steven's best friend. Whenever she gets the chance, she will tag along any adventures the Crystal Gems and Pines Twins are on.

  • The Baby of the Bunch: She's only a few months behind the twins, but she's still the youngest of the four kids.
  • Beware the Nice Ones: She becomes quite cross in "Copies and Clones" after hearing Pacifica insult Mabel, Candy, Grenda, and Steven.
    Mabel: Wow, Connie, I didn't know you could be so... hostile. It's kinda scary honestly.
    Connie: Well, what can I say? Steven's not the only one who's feeling feister than usual tonight.
  • Birds of a Feather: Much like between Steven and Mabel, she and Dipper get along quite well thanks to their common interests.
  • Jumped at the Call: She's always more than ready to accompany Steven and the twins on any adventure she can come along on.
  • Meganekko: Until this verse's "An Indirect Kiss".
  • Not So Above It All: She seems perfectly fine leaving Pacifica with the Lilliputtians in "The Golf War".
  • Not So Different: Despite the disdain she has for Pacifica, they have some pretty interesting similarities. They were both brought up in affluent homes where they were repressed by their parents, albeit to different degrees and in drastically different ways. However, while Pacifica chooses to react to her upbringing by being as cruel and abrasive as her parents, Connie had the privilege of being raised by much better parents, allowing her to make genuine friends.
  • Only Sane Woman: She's probably the most levelheaded out of the four kids, especially when compared to Steven and Mabel's shared Cloudcuckoolander behavior and Dipper's occasional tenancy to overreact.
    • She's also the most suspicious of the Bill possessed Dipper in "Sock Opera".

Gideon Gleeful

Better known by his stage name Lil' Gideon. A (phony) psychic who has a crush on Mabel and a grudge against the Crystal Gems.

  • Evil Cannot Comprehend Good: He doesn't see why the Crystal Gems would use their powers for good and states he would rather use them for personal gain.
  • Evil Counterpart: He already serves as this to each of the members of the Pines family (see the show's character page for more details), but he's arguably even more of one to Steven. They're both well-liked by the people of Gravity Falls, though for different reasons, and they both come across as being socially talented, friendly, and charming. However, unlike the fake display Gideon puts on to get what he wants, Steven is always genuine in his kindness. Their wardrobes are even opposing colors, with Steven's red shirt opposite Gideon's primarily blue clothing.
  • Evil Is Petty: He holds a grudge not just against the Pines, but against the Crystal Gems as well, mostly because they stand to throw a wrench in his plans.
  • Glad I Thought of It: Takes credit for the escape plan him and his goon use this way.
  • Green-Eyed Monster: Gideon is extremely jealous of the close friendship Steven and Mabel have, even if its completely platonic.
  • I Will Punish Your Friend for Your Failure: He threatens to do this to Steven in "Measure Up" if the Watermelon Stevens don't do as he says. Needless to say this backfires on him more than once.
  • Mistaken for Romance: Gideon scornfully thinks there's something going on between Steven and Mabel, when there clearly isn't. He even assume Steven is cheating on Mabel with Connie.
  • Murder the Hypotenuse: He thinks that Steven has stolen Mabel's affections away from him, and tries to kill him and Dipper for it.
  • Sitcom Arch-Nemesis: With both Stan and the Gems.

Pacifica Northwest

The richest, most popular girl in Gravity Falls and is in no way modest about it.

Robbie Valentino

An angsty teenager and Wendy's boyfriend. At first.

Laramie "Lars" Barriga

Part of Robbie's gang and a friend of Steven's.

  • Demoted to Extra: Compared to Steven Universe. Most of the chapters based off of the episodes with his Character Development instead have his role given to Stan and/or Ford to the point that in the released chapter title list for Arc Eight, one of the biggest episodes of said development looks like it's going to have Steven do it with Stan instead. Even the "Stonemason Arc" seems like it's being done in place of "Lars of the Stars."

    Adults of Gravity Falls 

Greg Universe

Husband to Rose Quartz, and Steven's father, Greg used to be a traveling musician, until he settled down in Gravity Falls after he met Rose.

  • Adults Are Useless: Greg has a brief moment of this in the "Summerween" chapter. The kids come to him, hoping he can hook them up with a good amount of candy to help save them from the Summerween Trickster, only to find that all the candy he had was stolen while he was asleep.
  • Bumbling Dad: Downplayed, but when it does happen, its usually Played for Laughs.
  • Does Not Like Magic: He still isn't much for "Gem stuff", but he also has something of an aversion to the weirdness of Gravity Falls itself, as hinted at in "Measure Up".
  • Hidden Depths: Word of God is that Greg knows about the portal and Stan's missing brother.
  • Hetero Sexual Life Partners: While we haven't seen them talking much yet, Greg seems to be this with Stan (See "The Mystery Shack" for details).
  • Intergenerational Friendship: With Stan and also with the twins.

Fiddleford McGucket

Gravity Falls' resident kook who has a surprising talent for inventing.

  • Ascended Extra: He gets a bit more screen time during Arc 7, where his engineering expertise is needed for the drill.
  • The Cloudcuckoolander Was Right: While the real Gobblewonker's existence is hinted at at the end of "Legend of the Giant Woman", its confirmed in "Waterfall Gem", meaning that McGucket wasn't entirely making it up. This is actually lampshaded by Soos:
    Soos: Isn't that the Gobblewonker? I guess Old Man McGucket wasn't so crazy after all.
    Amethyst: Either that or he built another giant robot.
  • What the Hell, Hero?
    • His first meeting with Ford in the present day during Arc 7 has him call out the latter for building the portal and nearly causing the end of the world. Ford shoots back that at least he tried to fix his mistakes, rather than hide with the Memory Gun.
    • His first adventure with Ford and the Gems had a quieter variation: He was disappointed at how Ford had zero interest in more down-to-earth matters like romance, how he was aiming for greater heights instead of just publishing his current findings, and finally, Ford's constant questioning about Homeworld to Rose, ignoring how sensitive of a topic it was.


     Other Gems 

Lapis Lazuli

A Homeworld Gem with the power to control water. She was trapped in a mirror for thousands of years before being set free by Steven, Dipper, and Mabel.

  • Because You Were Nice to Me: She forms a friendship with Dipper and Mabel as well as Steven while still trapped in the mirror because of the genuine kindness they show her.
  • Big Sister Instinct: Very protective of Dipper, Steven and Mabel. She even tries to stand up to Jasper to protect them.
  • Deadpan Snarker: Even in her debut chapter, she's more sarcastic while trapped in the mirror than she is in the episode. This can especially be seen in her interactions with Dipper.
  • Fantastic Racism: She seems to have a bit more of a grudge against humans in Universe Falls when compared to the show:
    Lapis: Humans... Crystal Gems... You're all the same! You only care about this place and nothing else!
  • Living MacGuffin: She's essentially this while trapped in the mirror.
  • Odd Friendship: With Dipper, especially when you consider he initially wasn't as enthusiastic about the mirror as Steven and Mabel were.
  • Put on a Bus: Both at the end of "Waterfall Gem" and "Jailbreak" - first, she leaves for Homeworld, and afterwards, she fuses with Jasper to protect Steven, Dipper, and Mabel.
  • The Bus Came Back: Returns in "Dipper and Lapis".
  • Would Hurt a Child: Through her water clones, she nearly ends up drowning Steven, Connie, and Dipper, and almost crushes Mabel. When the kids confront her about this later on, it's clear she's at least remorseful about it.
  • Wrong Name Outburst: Accidentally says "Dipper" instead of "Steven" in the Universe Falls version of Chille Ted.

     Minor Antagonists 


An elite Homeworld quartz sent to act as Peridot's escort while investigating Earth.

  • Even Evil Has Standards: She doesn't like Bill any more than the other Homeworld Gems do.
  • Kick the Dog: She backhands Dipper hard enough to draw blood when she’s getting Lapis to fuse with her.
  • Never Homeworld’s Fault: She blames Rose Quartz as the reason that Earth will be destroyed, despite the fact that Homeworld has, so far tried to colonize the planet for their own uses and kill all of the native life and, after it became clear they would lose the Rebellion, planted the Cluster there to eventually emerge and destroy the world, and that at least half the reason for the Rebellion was to protect Earth.
  • Puny Earthlings: She really doesn’t care in the slightest about humans, despite knowing they’re sapient beings.
  • Put on a Bus: After becoming Malachite, Lapis drags her into Lake Gravity Falls.
  • Would Hurt a Child: Has no issues with attacking Dipper and Mabel, despite knowing that they're not Gems, unlike with Steven.


A gem technician sent by Homeworld to reactivate the Kindergarten and check on the Cluster to view its progress.

  • Adaptational Angst Upgrade: She has an even stronger Freudian Excuse for not wanting to fuse with Garnet this time around, since she actually tried fusion before...with an Eldritch Abomination who ultimately bodyjacked her.
  • Foreshadowing: She comments that Yellow Diamond got the coordinates for the rebel base from an "unknown informant". In other words, probably Bill Cipher.
  • Ignored Expert: After detecting the colossal energy spikes from the Portal, Peridot tries to tell Jasper they should investigate them. Emphasis on “tries”, since Jasper is focused on Steven.
  • Must Have Caffeine: In "To Con A Clod", Stan introduces her to coffee, and she is quickly hooked.

Agents Powers and Trigger

Agents sent by the US Government to Gravity Falls to investigate the strange power spikes caused by the Portal, who quickly discover that far more is going on than they first thought.

  • Accidental Pun: When the Hand Ship arrives, Powers says they’ll only send for backup if things get out of hand. Trigger chuckles at the joke, but it’s apparent Powers didn’t catch his joke.
  • Not What I Signed Up For: When Peridot and Jasper arrive, they decide to not get involved unless things get out of hand, since their mission is to observe only.


A race-loving demon who haunts the Gravity Falls landmark aptly named Demon's Peak. She appears in "Gravity Falls Drift" and offers to give the kids an edge in their race against Kevin and his team.

  • Affably Evil: To the point where she can barely be called evil in the first place. The only villainous thing she does is blast a tree onto the road so one of Kevin's teammates almost crashes into it, forcing her to stop. Other than that, her attempts to help the kids cheat at the race are fairly harmless and she actually hopes to race with them again some day.
  • Competition Freak: Zoom gladly admits to being obsessed with speed and winning.
  • Everyone Has Standards: She thinks Bill Cipher gives demons a bad name, and feels similar about Kevin giving racers a bad name with his sleaziness and poor sportsmanship.
  • Literal Metaphor: She even introduces herself as a "speed demon."
  • Transforming Vehicle: She can conjure a ghostly car that can turn into a motorbike.

    Main Antagonists 

Bill Cipher

A mysterious dream demon known for his odd, triangular shape and sick sense of humor. No one knows what Bill is planning, but he has formed an alliance with the Homeworld Gems.

  • Adaptational Villainy: Bill was already vile enough in canon. MiniJenn still found ways to make him worse. See Kick the Dog below to see how he topped his canon counterpart.
  • Big Bad Duumvirate: With Yellow Diamond, and White Diamond by proxy.
  • Black Sheep: In the world of Steven Universe, he really stands out in terms of morality. Villains from SU are evil for deep-seeded emotional issues. Bill on the other hand is a repugnant villain with no redeeming qualities; existing solely to evoke hatred and disgust from his actions.
  • The Dreaded: Those in the loop about him tend to be justifiably fearful of him. Dipper and Ford are even more worried about him when they realize that he could try what he did with Peridot on another, more powerful Gem to make an even more dangerous version of Pyrite.
  • Eye Scream: Threatens to gouge out one of Dipper's eyes at one point.
  • Foil: To Yellow Diamond. While they are both Big Bads who are yellow, Yellow Diamond is a Lawful Evil tyrant with No Sense of Humor and some humanizing traits, while Bill is a Chaotic Evil demon with a sick and twisted sense of humor and a heart as black as night.
  • Foreshadowing: Quite fond of dropping this. Probably the most notable example right now is his hint of his alliance with the Great Diamond Authority:
    Bill: A darkness approaches. A day will come in the future when everything you care about will change. And when it does, I won't be the one you'll have to worry about...
  • The Friend Nobody Likes: None of the Homeworld Gems can stand Bill. Blue Diamond and Peridot are terrified of him, Jasper is openly disgusted by him and even Yellow Diamond is only tolerating him because of the deal they struck.
  • Fusion Dance: Can somehow fuse with Gems. His first fusion, Pyrite, formed with Peridot, is so powerful it takes Maven, Sardonyx, Opal, and Sugilite to turn the tables, and Dipper and Ford are justifiably worried about what happen if he finds a more powerful Gem and pulls the trick again.
  • The Gadfly: He seems to enjoy teasing Yellow Diamond, much to the latter's annoyance.
  • Hidden Agenda Villain: While his canon plans are presumably still in motion, he also has a fixation on acquiring Rose/Pink/Steven's Gemstone.
  • Horrifying the Horror: According to supplementary material, even he's terrified of White Diamond and he's not afraid to admit it.
    Bill: “…There’s something seriously wrong with that rock. And coming from ME, that’s saying something.”
  • Jerkass: There is nothing tragic or sympathetic about him. Everything he does is purely for his own sick pleasure.
  • Kick the Dog:
    • As mentioned under Sadist, he psychologically tortures Steven to the point of tears and laughs.
    • When he possesses Dipper in the UF version of "Sock Opera", he not only destroys the laptop, but Dipper's pictures of him and Lapis (after he had used Lapis's state to strike at him emotionally when first speaking to him), clearly enjoying the emotional pain he's causing.
    • In the second part, he not only takes glee in torturing Dipper's body, but forces Steven into a deal, Steven's silence in exchange for Bill ceasing his torture, but he clearly enjoys the emotional pain he causes Steven over even the slightest slip and his threats of what he's going to do to Dipper (and does on one occasion).
  • Knowledge Broker: Seems to serve as this for Yellow Diamond considering how he told her how the Red Eye was destroyed by rebels.
  • Not So Different: Him not telling Yellow Diamond that Pink Diamond faked her shattering is similar to the fact that in canon, White Diamond is implied to have found out about it, but never bothered to tell Yellow and Blue.
  • Perception Filter: Can apparently keep those unaware of his possessions from noticing anything off about his voice and eyes.
  • Politically Incorrect Villain: He refers to the Gems as "rocks" on numerous occasions. Considering how a rock is used to imply denseness and stupidity, this can be considered a worse slur than Peridot's use of the word "clod".
  • Sadist: Is already this in Gravity Falls, but it really shows in Universe Falls when he psychologically tortures Steven with a nightmare of the Crystal Gems telling him that he will never live up to them. It's even to the point where he laughs upon seeing Steven break down in tears!
    • In addition to torturing Dipper's body, he clearly delights in the emotional pain that he's causing Steven in the process.
  • Teeth-Clenched Teamwork: He and Yellow Diamond don't like each other at all. They're only working together out of convenience.
  • Unconventional Formatting: His dialogue is all typed in an italic font.
  • Villain Override: When Pyrite starts losing, he forcibly takes full control of the fusion, not that it helps him much.
  • Voices Are Mental: With his possessions, but he can hide that from anyone unaware of the possession in the first place.

Yellow Diamond

One of the matriarchs of the Diamond Authority, she and (probably) the rest of the Diamond Authority have formed an alliance with Bill Cipher.

White Diamond

The reclusive leader of the Diamond Authority.


How well does it match the trope?
