"Fighting is my life! It's what I was made for!"

A warrior from the Gem Homeworld who fought against Rose Quartz's army more than 5,750 years ago. She returns to Earth as Peridot's escort, and later reveals herself to be formerly of Pink Diamond's Court.

     A to E 
  • The Ace: Considered the paragon of her kind by Homeworld for both being born absolutely perfect and being, to their side, a war hero. This is reflected in both her status and her capabilities. It's telling that the Topazes, despite being considerably higher ranked than the average Quartz according to Word of God, don't seem as powerful as she is.
  • Admiring the Abomination: Jasper considers Lapis' apparently unprecedented hostile takeover of Malachite, and her ability to hold Jasper down and wrest control of their fusion from her, to be a positive attribute, even mentioning how impressed she is that Lapis "held out". She takes it a step further in "Alone at Sea": while it's clear that Lapis is starting to realize her conduct was monstrous in its own way, Jasper agrees... and wants to re-establish that relationship on those terms. She isn't shy about saying why:
    Jasper: I'm the only one who can handle your kind of power!
  • Ain't Too Proud to Beg: In "Alone at Sea", when she finally finds Lapis, she grabs her hand, gets on her knees, and outright begs Lapis to fuse with her again.
  • Alas, Poor Villain: In "Earthlings", Jasper is revealed as a vengeful, loyal soldier who had everything taken from her by Rose Quartz, roaring at Steven for everything Rose Quartz did to her colony, her planet and to Pink Diamond, and is desperately lonely when everyone she fuses with leaves her. Losing herself to corruption, she's then bubbled by Amethyst who sadly acknowledges her as a sister for the first time. Even more so with the later reveal that Rose was Pink Diamond, meaning her revenge was completely meaningless to begin with.
  • Aloof Big Sister: Amethyst sees her as this. Though (most) Gems lack a concept of family, Jasper and Amethyst are "sisters" in that they are both Quartz soldiers made on Earth, and Amethyst calls Jasper "sis" after she's corrupted and poofed. Amethyst came out small and "defective" due to emerging 500 years later than she was supposed to, while Jasper is the most perfect Quartz ever made, which causes Amethyst to see Jasper as everything she wishes to be. Jasper is pleased to rub this in Amethyst's face in their first fight, but the next time she only reacts with contempt.
  • Anatomy Anomaly: The first, and for a long time the only, character drawn with eyelashes.
  • And I Must Scream: Lapis Lazuli traps her in her own body at the bottom of the ocean. When we next meet her in "Chille Tid", she's become completely unhinged.
  • Arch-Enemy:
    • Seems to think of Rose this way. It's unclear whether this was mutual on Rose's part or if Jasper was an Unknown Rival. It is revealed this is because Rose shattered Jasper's original Diamond: Pink Diamond. note 
    • As a result of trapping her in the ocean for months and her cruel behavior to Steven plus her treatment of her when she was forced to be her informant before the following events that happened, Lapis sees her as this.
    • After her beatdown and "Reason You Suck" Speech at Jasper's hands, Amethyst comes to regard her as this.
  • Arc Villain: Of the Season One finale. Season 3 sees her promoted into a longer term version as of "Alone at Sea".
  • Armor Is Useless: Subverted. While her Crash Helmet is normally a weapon, it turns out to work as good armor when it lets her survive a slash from Stevonnie that had enough power behind it to drive her through the monster she was riding.
  • Arrogant Kung Fu Girl: She claims the only reason Garnet was able to beat her was because she was a fusion. In fairness to her, the only Crystal Gems who have ever been able to defeat her (aside from Lapis, and she's got the biggest advantage of any Gem on Earth) have been fusions.
  • Astonishingly Appropriate Appearance:
    • Jasper's alternating red/orange colorization comes from the red sandstone she emerged from.
    • Her corrupted form, while taking the same figure as the Great North monsters, also resembles a ram with her horns and hooves where her feet used to be. Fitting for someone as hard-headed as her and often headbutting her foes with her Crash Helmet.
  • Authority Equals Asskicking: Seems to outrank Peridot, and is definitely the better fighter of the two. Peridot's comments regarding quartz Gems and their role in Homeworld in 'Too Far' suggest it's more a case of Asskicking Equals Authority; Jasper is part of a higher caste because of her physical prowess.
  • Avenging the Villain: Reveals that part of the reason she wanted to destroy Rose so bad was to avenge Pink Diamond.
  • Badass Cape: Jasper comes out of Peridot's ship wearing a cape with a High Collar of Doom. She isn't wearing it back inside the ship when she fights Garnet again. One of the show's writers/storyboard artists states that the sole reason Jasper wore the cape was to look "intimidatingly fabulous".
  • Badass in Charge: As stated above in Authority Equals Asskicking, she seems to outrank Peridot and Lapis and is clearly in charge of the mission. And she fought against Rose Quartz's forces in the war and survived, and later fights against Garnet in a pretty even battle despite the latter being a fusion. In "Chille Tid", we learn that it's taking Lapis' constant hyper-vigilant concentration and the weight of the entire ocean to keep her, and by extension, Malachite from breaking free and going on a rampage. It only takes a single moment of distraction from Steven for her to take control from Lapis.
  • Bad Boss: On top of her obnoxious, domineering attitude towards Peridot, this can be seen when she later captures an "army" of corrupted gems to fight the Crystal Gems, by violently poofing them and forcing them into cages and delivering angry, insulting lectures about how pathetic they are compared to her.
  • Barbarian Long Hair: Her hair is a mess, and like all known Quartzes, it's huge and long. Her being barbaric goes without question.
  • Battle Aura: She surrounds herself with one during her Rolling Attack.
  • The Beastmaster: By "Gem Hunt", Jasper has started to gather corrupted Gems, in order to turn them into an army to battle Rose. As it turns out she isn't very good at controlling them, as they all flee from her abusive treatment first chance they get.
  • Berserk Button:
    • Fusion has a tendency to drive her up the wall, not because of the Homeworld taboo but because she continually gets her butt kicked by every Fusion she encounters.... and she's not used to losing.
      Jasper: I will not be beaten by another Fusion!
    • "Earthlings" makes it clear that Jasper absolutely hates Rose Quartz because Rose shattered Pink Diamond, the person Jasper was originally loyal to and served under. Ironically, Rose was Pink Diamond.
  • Beta Test Baddie: Inverted. Peridot assumes this trope will be at play between Jasper and Amethyst because Jasper came from the far inferior Beta Kindergarten (which was a poorly done, flawed rushjob intended to pump out troops like mad to fight the Rebellion), and thus should have some inferiority to Amethyst (who came from the much better handled main Kindergarten). It turns out the exact opposite is true: Jasper wasn't just properly formed, she was perfectly formed to the point Peridot calls her "the ultimate Quartz".
  • Bigger Stick: She quickly defeats Garnet by using a gem disruptor in their first fight. When Garnet destroys it in their second one, the fight is much more even-handed and ultimately ends in Jasper's loss. She doesn't get it as bad as Peridot, as she has military experience from before the disruptors were invented.
  • Blood Knight: While she does seem to be military and dealing with the Gems seems to be her job, she decidedly enjoys every second of it and laments not having had the chance to pound Rose Quartz into the ground.
  • Body Horror: After fusing with a corrupted Gem, her body starts to hideously and graphically mutate into a feral form completely unrecognizable.
  • Boomerang Bigot: She likes speaking down about the Earth... but it's eventually revealed she was born there, and considers herself the only thing of worth to come from it.
  • Born Winner: Her exit hole is the most perfect one Peridot has ever seen, meaning she was born as a completely flawless "ultimate Quartz".
  • Brains and Brawn: The brawn to Peridot's brains as the big, muscular warrior/guard who keeps the prisoner Gems in line. Notably, though, she displays both brains and brawn, directing Peridot both in combat and out to efficient results. By ordering Peridot around and attacking herself, she was able to disarm and capture all the Crystal Gems plus Steven.
  • Broken Ace: Despite being the Ultimate Life Form by Quartz standards, she has some serious issues. She'd had a chip on her shoulder since Pink Diamond died and Homeworld lost Earth, seeing both as her failure regardless of her personal performance. Further defeats at the hand of the Crystal Gems made her lose confidence in her own fighting strength, and thus think of herself as completely worthless.
  • The Brute: As the most physically formidable antagonist seen thus far - able to match Garnet blow-for-blow and overpower her on several occasions. In "Alone at Sea", she outright calls herself one.
  • The Bus Came Back: In "Chille Tid", "Super Watermelon Island", "Alone At Sea", and "Change Your Mind".
  • Cain and Abel: The Cain to Amethyst's Abel, as both were born from Earth Kindergartens (different ones, but still). Amethyst even refers to Jasper as "sis" after Jasper's physical form was destroyed. With The Reveal that Pink Diamond was Steven's mother, Jasper could considered Steven's sister as well since she was created to serve Pink Diamond just like Amethyst.
  • Cat Smile: Very subtle, but her mouth briefly shapes like this when she meets again with Lapis. She does this in "Earthlings" as well, giving her a resemblance to Amethyst.
  • Clipped-Wing Angel:
    • When she fights Steven and Amethyst fused as Smoky Quartz, Jasper finally snaps at being beaten again by a "fusion" and decides to fuse with one of the Gem Monsters. This ends up biting her in the ass hard as not only did it not power her up enough, but it also ended up infecting her with whatever the corruption was after they defused.
    • Her corruption itself caused her to grow even larger and completely covered her body in deadly-looking spikes, but it weakened her Nigh-Invulnerability enough for Peridot to easily impale her with a metal pole.
  • Combat Pragmatist: She wields a gem destabilizer in addition to her gem weapon, allowing her to knock out other Gems in one hit if she can connect with the former. Notably, she hangs onto said destabilizer when Garnet challenges her to fight without it.
  • Combat Sadomasochist: In "Alone At Sea", it's revealed that Jasper is fascinated by the experience of being at someone's mercy after being the strongest in the room her whole life, falling to her knees and begging Lapis to fuse again, and insisting she's the only one who can handle the abuse Lapis dishes out.
  • Contralto of Danger: She's got a notably deep voice and is quite evil.
  • Cool Helmet: Her weapon is a helmet with a hammer-like block in front.
  • The Corruption: In "Earthlings", after fusing with a corrupted Gem, she becomes one herself.
  • Curb-Stomp Battle: Her fights with Amethyst which shows just how dangerous a fully developed Quartz is against a defective one. Finally on the receiving end of this in her battle with Smoky Quartz.
  • Defiant to the End: "You can't manipulate me, Rose Quartz!"
  • Delinquent Hair: Her helmet is visually similar to a very front-heavy pompadour.
  • Depending on the Artist: In "The Return", her jaw is much larger, her Rapunzel Hair is slightly elevated, and her body type is slightly broader. In "Jail Break", her jawline is less defined, her hair is hanging loosely, and her body type is smaller.
  • Determinator: An inherent trait of being a Jasper.
    Jasper: Jaspers don't give up! Jaspers keep going until we get what we want!
  • Does This Remind You of Anything?:
    • When Jasper pressures Lapis Lazuli into fusing, it's reminiscent of someone pressuring a reluctant partner into physical intimacy.
    • Many of the interactions between Jasper and Lapis are reminiscent of a VERY unhealthy romantic relationship. After Malachite is broken apart, Jasper tracks down Lapis and begs her to fuse into Malachite again.
    • After fusing with a corrupted Gem, Jasper catches a condition that causes her body to deteriorate.
  • Doomed Hometown: Earth, but specifically Earth-the-gem-colony. She essentially views Rose Quartz as the person who destroyed her home and forced her into constant strife from the moment of her creation, which makes her stance on Earth far harder to change than Peridot's.
  • Dragged Off to Hell: This trope is invoked when Lapis fuses with her into Malachite and then forcibly drags them both down to the ocean floor as Malachite desperately tries to keep her grip onto the beach.
  • Dramatically Missing the Point: After spending a long time fused with Lapis under the sea, she comes to admit she was wrong about fusion and sees the use in it. But she only enjoys fusion for the extra power it provides, and fails to understand that the most important part of fusion is a loving (or at least emotionally stable) relationship between the component Gems. She doesn't understand when Lapis refuses to fuse with her again, not wanting to resume their abusive relationship, and she is ultimately transformed into a corrupted Gem when she fuses with one in a last-ditch attempt to regain the power she had as Malachite.
  • Dramatic Irony: Strange how Jasper has a grudge on Rose Quartz for shattering Pink Diamond, when in reality, Rose was Pink Diamond herself. Jasper is fighting the one she is supposed to avenge, but doesn't know the truth behind the deception.
  • The Dreaded: As the most powerful foe fought by the Crystal Gems, everybody except arguably Lapis is afraid of her, even corrupted Gems.
  • Evil Cannot Comprehend Good:
    • She at first sees the Fusion Dance as a mere power booster without understanding the deeper connection. When she tries to fuse with Lapis to even the odds, she didn't expect Lapis to betray her for Steven's sake.
    • In "Earthlings", while she manages to start figuring out how Rose, and now Steven, could gain the loyalty of other Gems, she can't get that friendship and kindness were the key, not manipulation.
  • Evil Counterpart:
    • To Amethyst. Both are hot-blooded, rude, brash, rely on brute strength, and love to fight. But while Amethyst loves to goof off and has love and compassion for others, Jasper exists to fight, is always serious, and doesn't get the importance of love. She also shares Amethyst's hair style and is physically similar to her, but larger, and they both attack with a spin dash. To further push the matter, Jasper is colored yellow, complementary to Amethyst's purple. "Too Far" reveals that Amethyst is a Quartz Gem like Jasper, with Jasper representing what a successful Kindergarten Gem should look like. By contrast, Amethyst is an "overcooked runt" that stayed in the ground too long, hence her short stature and comparatively weaker abilities. This comes to a head in "Crack the Whip", where they finally fight. Jasper, thanks to a combination of training and her superior capabilities, beats her down easily. "Beta" takes this even further by revealing that Jasper was also made on Earth, in the Beta Kindergarten. All the other holes are misshapen while hers is the only one that's perfect. And while Amethyst sees Jasper as her Arch-Enemy, Jasper views her with a sort of morbid curiosity.
      Amethyst: I can fight just fine.
      Jasper: Well then, let's see it!
      Jasper: You... could have been me.
    • To Garnet. Both are no-nonsense heavies and the bosses of their team, both prefer hand-to-hand combat and taking a hands-on approach to difficult situations, conduct themselves like people with rather healthy egos, and can take a tremendous amount of physical punishment. Garnet is playful, maternal, and protective, her confidence coming from her being the result of a fusion of two Gems who are deeply in love, and she takes a tremendous amount of pride in being a permafusion, whereas Jasper is ruthless, savage, and short-tempered, treats fusion as "a cheap trick," and treats her allies as mere soldiers. This gets even stronger in Season 3, where she wants to be fused again, but in a toxic and unhealthy relationship opposed to Ruby and Sapphire's loving one.
    • To Rose Quartz. Both are large and powerful Quartz-type Gems, but Rose was feminine and elegant, softly curved and with a soothing voice. She was also incredibly kind and adored Earth and its lifeforms. Jasper is much more masculine and rugged, a Blood Knight with a short fuse and a gravelly voice who reacts to humanity with disgust. This is compounded with the revelation that they were both apparently made on Earth. Whereas Rose believed in choosing your own path and encouraged other Gems to grow beyond their programming, Jasper has fully embraced her allotted role as a warrior and seems repulsed by those who act outside of Homeworld's order. Finally, it comes up in their relationship to Pink Diamond: Both were apparently made for her, but Jasper, from what's been seen, was extremely loyal to her and held a chip on her shoulder towards Rose, who had supposedly personally shattered said Diamond in the course of her rebellion.
  • Evil Is Bigger: Jasper is larger than any of the present Crystal Gems that isn't a fusion—and even some that are!
  • Evil Is Hammy: Though she's still a serious villain, she shows up to Earth in a Badass Cape just to look cool and almost all her lines are very intense and shouted. She gloats to her enemies, especially "Rose Quartz" whenever she can and even plans dramatic entries and exits.
  • Evil Sounds Deep: She has a noticeably gruff voice.
  • Eye Scream: When turning into a Gem monster, her eyes form stalagmites in her sockets.

     F to J 
  • Famous Last Words: "Wha... My Diamond! Your Diamond! PINK DIAMOND!!!" before getting corrupted and bubbled.
  • Fangs Are Evil: Gets drawn with these in "Earthlings"; appropriate for the events of that episode.
  • Fatal Flaw: After her fusion with Lapis, her obsession with fusion and the power it can bring becomes this. It backfires on her big time in "Earthlings", where her fusion with a corrupted Gem infects her with corruption as well.
  • Fate Worse than Death: When she fuses with Lapis, Lapis takes control of the fusion and drags them both to the bottom of the ocean. Jasper is thus trapped under the ocean and inside her own body, and if Chille Tid is any indication this is not a pleasant experience.
    • Finally, when fighting Smoky Quartz, she fused with a corrupted Gem and was corrupted herself.
  • Final Boss: Of Season One.
  • Foil: To Peridot. Peridot is an Era 2 Gem, made without any of the powers Jasper was born with or the amazing constitution Jasper boasts. While they're both incredibly durable, Peridot's physical toughness is played for laughs while Jasper's is always played dead serious. Building on this, Jasper is a Knight of Cerebus to Peridot's often laughably evil nature and own innate goofiness. Most importantly, Peridot was a Gem born on Homeworld that came to Earth and grew to love it dearly. Jasper was an Earth-made Gem that hated Earth with a passion, was fiercely loyal to Homeworld.
  • Forgotten Fallen Friend: In "Are You My Dad?" and "I Am My Mom", neither Aquamarine or Topaz spare even a moment to look for her and in "The Trial" she's unmentioned despite Eyeball being allowed back on Homeworld without having completed her mission of retrieving Jasper.
  • Freudian Excuse: Was literally fighting a war from the moment she was born, a war that was half-way over before she was born at that. She's had it ingrained in her head that the planet she was born on is worthless because the Hostile Terraforming the Gems attempted on it never finished, and like Peridot is more or less indoctrinated to worship the Diamonds fanatically. The loss of Pink Diamond and Earth as her home colony made her fanatically homicidal and gunning for revenge on Rose Quartz, now reincarnated as her son, Steven.
  • Fusion Dance: Fuses with Lapis Lazuli at the end of "Jailbreak" and the Green Alpine Monster in the Climax of "Earthlings".
  • Guttural Growler: She speaks with a gravelly alto voice.
  • Hartman Hips: In "The Return", her hips are even wider and thicker than Garnet's, though her mid-section is also thicker. They aren't as big in "Jail Break", but still clearly large enough to quality for this trope.
  • Hate Sink: She was this up until her tragic fate in "Earthlings" which also shed light on her motivations. Eventually, Aquamarine appeared to fill the void.
  • The Heavy: As of "Alone at Sea" she seems to have become this.
  • Hellish Pupils: Subtle and downplayed. Her eyes are naturally yellow, but several times the irises and pupils appear elongated, especially when she flashes her Slasher Smile.
  • A Hero To Her Hometown: If the Ruby Squad is any indication, Jasper was still a highly respected member of the Gem warrior caste, as many of them positively fangirl at the idea of being around her. She most likely gets along better with other Warrior gems.
  • Hey, You!: Jasper calls Steven "Rose Quartz", mentions Yellow Diamond, her apparent superior, and Pink Diamond, her former superior, and calls Lapis by her name only when trying to persuade her into fusion. She otherwise calls no one by their name. She calls Pearl "some lost, defective pearl",note  Amethyst an "overcooked runt",note  Garnet a "shameless display",note  and simply "brat" for Lapis. This is taken to a terrifying extent when she recognizes Steven in the dreamscape in "Chille Tid", and her furious utterances of "You!" becomes a Madness Mantra.
  • Hidden Depths:
    • In "Alone at Sea", while gushing about being Malachite, Jasper seems to put particular emphasis on having been able to fly, at least as much as how Malachite "was bigger and stronger than both of [them]".
    • In "Earthlings", just before she devolved into a Gem Monster, Jasper calls Earth "my planet" and reveals that her Diamond was originally Pink Diamond. Jasper is also extremely bitter at "Rose" for taking both away from her.
    • Also in "Earthlings" she shows an insecure or lonely side when she mutters that no one she fuses with ever wants to stay. She also believes that anyone who has hit bottom will follow anyone who makes them feel like less of a failure, implying this is how she may feel being under Yellow Diamond's command.
  • Hoist by Her Own Petard:
    • Garnet uses Jasper's own momentum to toss her into the ship's power core.
    • Turns out pressuring Lapis to fuse with her was also a bad move, as it gave Lapis an opportunity to use a rather inventively brutal means of capturing her.
    • She ends up getting Corrupted herself after fusing with a Corrupted gem.
  • Horned Humanoid: When she's healed of the Corruption, she retains two blue horns on her head.
  • Hypocrite:
    • Her attitude toward fusion changes rather quickly after Garnet defeats her, yet she still continues to belittle others for not following Homeworld's rules after she's done so herself.
    • Jasper hates weak and "defective" Gems because they're of no use to the Diamonds. Yet she treats her mission statement as more of a suggestion, from hastily determining some other goal to be "more important" to a nigh-treasonous tendency to put her own grudges first. We learn later that Jasper does consider herself to be serving the will of her Diamond...PINK Diamond, who was shattered over five thousand years ago and who appears to have been officially Un-Personed by the three surviving members of the Diamond Authority.
  • Implacable Woman: She is very, very hard to stop. Whether it's sinking into the earth's mantle or being thrown several miles across the ocean, she will come back, just as determined as ever.
  • Impaled with Extreme Prejudice: After her corruption, she gets poofed when Peridot uses her metal powers to impale her with a metal rod.
  • Improbable Weapon User: She fights with a helmet. However, it has a hammer-like block added to it and she uses it to defend as much as she does to attack.
  • Inertia Is a Cruel Mistress: Garnet defeats her by redirecting her own momentum to send her into the ship's power core.
  • Inferiority Superiority Complex: While she is normally very self-assured, she places all of her self-worth in her fighting ability, and she tends to come unglued in situations where her strength comes into question. After losing to Garnet, she immediately shifts gears and claims that it was not a fair fight because her opponent is a fusion, even after mocking the tactic just before. She also tries to cling to Lapis to make herself feel stronger, both before and after forming Malachite. Considering the fact that she was the only and most perfect Gem of a Kindergarten that was made solely for the purpose of Cannon Fodder for the war, it's highly likely she puts so much emphasis on her fighting ability because that's the only reason she exists.
  • Informed Attribute: Quartz soldiers are said to be loyal, which is quite jarring when Jasper comes off as a Psycho for Hire with a blatant disregard of Yellow Diamond's orders in favor of obtaining more power and getting personal revenge on Rose Quartz. Especially when she fits every other description of the ideal Quartz archetype to a T. Subverted when it turns out that Jasper actually has this Undying Loyalty for Pink Diamond, who she was made for. It's possible that Jasper disregards Yellow Diamond's order because she knows how she treated Pink Diamond prior to her "death".
  • Ironic Hell: Derides Garnet for being a perma-fusion. Gets stuck as one for several months. Later becomes infected with The Corruption after forcefully fusing with a corrupted gem to win a battle... against another fusion.
  • Ironic Name: Jasper stones are associated with earth, stability and tranquility. Jasper here is a Hot-Blooded brute who invades Earth, and later appearances in the show see her becoming more and more unhinged. In addition, jasper is a variety of quartz, making her rivalry with Rose Quartz and Amethyst (and, by extension, Steven) especially noticeable.
  • It's Personal: Her loathing toward 'this miserable planet' sure takes on a different color once it is revealed to be her place of origin, and it turns out she really hates Rose for killing their former liege, Pink Diamond.
  • Jerkass: She is overall a hostile, intentionally rude, callous, Arrogant Kung Fu Girl who looks down on nearly everyone, except Rose Quartz. Her introduction has her taking turns individually insulting the Crystal Gems before deciding collectively they're not worth her time. She's notably a jerk even to her own allies, ensuring that even pre-redemption Peridot couldn't stand her. Ironically enough, it's Peridot who's the one to ultimately defeat her.
  • The Juggernaut: Electrocute her, drown her in the ocean floor, punch her miles across the ocean, it won't stop her for long. It says volumes that it takes her being corrupted into a weaker Gem Monster for the Crystal Gems to defeat her once and for all.

     K to O 
  • Karmic Transformation: In "Earthlings", Jasper has spent who knows how long capturing and abusing Corrupted Gems to try and force them to be her personal army, especially the one she forced to fuse with her, while demeaning them, calling them weak failures. In the end, forcing one to fuse with causes her to contract The Corruption, turning her into a mindless Gem Monster just like them. Even after being cured, the remnants of her transformation leave Jasper as one of the "off colors" she so despises.
  • Kick the Dog: In "Crack The Whip", Jasper suplexes a corrupted Gem to prevent it from running away from a fight. By this point in the show, it's pretty much established that the corrupted Gems are unfortunate victims to be pitied. At the same time, Jasper's doing this to a giant yeti monster the size of a small house, so it also serves to show how dangerous Jasper can be.
  • King Mook: She's the 'perfect' ultimate Quartz, making her considerably stronger than the rank and file Quartz soldiers. She's capable of fighting Garnet one on one, who was capable of taking on entire platoons of normal Quartz Gems during the War.
  • Knight of Cerebus: She's the first sentient enemy that Steven didn't try to befriend or reach out to. Unlike Lapis, who had a positive introduction, and Peridot, who was foremost concerned with her mission, Jasper is introduced as a pure aggressor, expressing contempt towards the Crystal Gems and disappointment that Rose Quartz wasn't there for her to fight. The battle with her has lasting impact, with Steven finally realizing how serious his Gem powers and the conflict with the Homeworld Gems is.
  • Large and in Charge: She looks to be as tall as Rose Quartz, and has the final say in the mission over Peridot, and was assigned to her in the first place because she needed the backup.
  • Laser-Guided Karma: After chastising the other Crystal Gems, especially Amethyst, Jasper ends up transforming into a weaker Gem and defeated by the "Shorty Squad."
  • Leitmotif: She's represented by a distorted bass sound. "Jasper" has a recurring harsh beat that sounds like an army on the march.
  • Lightning Bruiser: Even stronger than Garnet, the Crystal Gems' main bruiser - and no slouch in the speed department, able to stay virtually on top of Garnet the entire fight and rush her several times with a destructive charge attack. Her downfall in "Jailbreak" came because she was going Too Fast to Stop and Garnet used her momentum against her, as well as a convenient power core.
  • Likes Clark Kent, Hates Superman: She adores and is fanatically loyal to Pink Diamond but loathes Rose Quartz, unaware they were the same person.
  • Little Bit Beastly: After her corruption is cured she still has horns and some greenish patches on her skin.
  • Living Emotional Crutch: Her status as Lapis' emotional stress ball/punching bag for her anger at what had happened to her. This is Deconstructed naturally in that this form of emotional "stability" turns out to be toxic for both Lapis and Jasper due to them being archenemies.
  • Locked Out of the Loop: It seems that she was never told that the Diamonds were responsible for The Corruption of the Gems left behind on Earth.
    • She was also unaware that Lapis had defected from Homeworld which is a prime reason for her not refusing back into Malachite and she also didn't know about Peridot becoming a Crystal Gem until "Earthlings".
  • Long Hair Is Feminine: Inverted even harder than with Amethyst. Jasper's hair is longer than any other non-fusion Gem's (proportionally, it's about equal to Amethyst), and she's an outright brute.
  • Madness Mantra: "YOU. YOU. YOU. YOU. YOU!"
  • Mask of Sanity: The first few episodes we see her, "The Return" and "Jailbreak", paint her as a stern, yet relatively reasonable individual for the most part. Then the mask slowly fades away near the end of the latter episode, and it's all but gone after the Malachite fiasco.
  • Meaningful Name:
    • While the spiritual nature of jasper in gemology contrasts highly with the character (see Ironic Name above), it is also associated with the planet Mars, fitting for someone who is as militant and aggressive as Jasper.
    • She's Hot-Blooded, ill-tempered, unpredictable and unstable, gives off a fiery Battle Aura and emerged out of the ground burning so hot that her exit hole turned to glass. Real life jaspers are typically formed from volcanic ash.
    • In addition to being a variety of quartz, jasper contains impurities from organic substances, so it's especially appropriate that she was made on Earth. With her firmly holding Homeworld's views on Earth and organic life, this also makes it an Ironic Name.
  • Misplaced Retribution: Tries to do this to "Rose Quartz" on the present day, not knowing she's talking to her son, Steven, and that she's been gone for a while now.
  • Mistaken Identity: She confuses Steven for Rose Quartz, believing him to be a "dulled-down version" of her, and keeps calling him Rose. This isn't helped by a Gem's known capability to shapeshift.
  • Mook Carryover: Jasper was originally created to serve Pink Diamond, but after Rose Quartz shattered her, Jasper was transferred to Yellow Diamond's forces.
  • Ms. Exposition: Her casual comments about the Rebellion, Rose Quartz and the Diamond Authority have made her this to the fanbase.
  • Muscles Are Meaningful: While Gems generally operate with Super Strength that can be disproportionate to their looks, Jasper is the physically strongest seen thus far, and the most muscular.
  • Never Found the Body: The Crystal Gems saw Jasper falling down a massive crack in the earth and are left with no way of finding her until she resurfaces.
  • Nigh Invulnerable: Jasper is extremely tough and hard to damage, even by Gem standards. Even getting thrown into the power core of a spaceship, resulting in the core exploding, which then causes the ship to crash and also explode, isn't enough to reduce her to Gem form. Against the Crystal Gems, only Garnet and other fusions stand a chance of defeating her. The ease at which other Quartz have been shown being poofed in comparison (Garnet and Bismuth alone are apparently sufficient to handle several platoons of Quartz soldiers on their own, Pearl being shown as curbstomping two, and Amethyst being the most frequently poofed Crystal Gem by her own admission) imply this might be unique to her as a "perfect" Quartz. When she is finally poofed, it's only after she's been corrupted into a weaker Gem monster.
  • No Indoor Voice: She yells almost everything she says, and when she isn't shouting, her voice is still harsh and intense.
  • Non-Humans Lack Attributes: There's no way the plunging neckline of her uniform would have been accepted if her chest wasn't totally featureless.
  • Nonstandard Character Design: Her eyes are noticeably less cartoony and more detailed than the Sphere Eyes the rest of the cast have. Ironically, despite being more masculine-looking than any other female (or male) character, she's the only one with normally visible eyelashes. Some of her facial expressions are more detailed than is typical, especially her Slasher Smile.
  • Not Quite Back to Normal: Even after her corruption is cured, she still has green patches and horns.
  • No-Sell: In "Earthlings", despite her training, Amethyst's best whip attacks can't do anything more than make Jasper flinch. Even a fully charged Rolling Attack that was strong enough to cause a small explosion does little more than scuff her chest.
  • No Sense of Personal Space: In her first appearance, Jasper constantly grabbed Lapis and in the next episode, she gets all into her face. Her general combat style also involves getting up close and personal with grabs and headbutts.
  • Not So Different: Both Jasper and Lapis turn out to have enjoyed some aspect of Malachite, the general Power High and Flight capability for Jasper and using Jasper as a living stress ball and punching bag for Lapis. Both, in part, miss each other after being defused.
  • Not Worth Killing: Zig-zagged. She came to Earth to finish Rose off, but is disgusted to see Rose in a weaker form as Steven, and decides to capture "Rose" back to Homeworld instead. After that fails, she still never attacks Steven, until her Sanity Slippage ensues in the Malachite realm and later Lapis rejects fusing again, which causes Jasper to attempt shattering Steven in a fit of rage. After that, Jasper goes back to her old ways and tries to create her own army and a complicated plan to take down the Crystal Gems instead of shattering Rose.
  • One Riot, One Ranger: Reveals in season 3 show her being sent to escort Peridot was more or less from Homeworld's point of view. They apparently saw Jasper alone as sufficient to keep Peridot alive on what they had every reason to think would be a monster infested Death World that may still have a few sapient hostiles left where a meteor sized space probe and a number of combat capable robots were destroyed. Given Jasper would've won outright without Steven and in season 3 managed to round up an entire army of Corrupted Gems on her own in a short period of time, they weren't entirely off-base.

     P to T 
  • Painful Transformation: Judging by her reaction, it's safe to say that the process of corruption is an agonizing experience.
  • Pet the Dog: Weirdly enough, her reaction to Peridot's Heel–Face Turn—the fact that she feels as though Peridot has "lowered" herself and "sacrificed her dignity" by working with the Crystal Gems isn't a very flattering assessment of the latter group, but it does seem to imply that she held some level of respect for Peridot.
  • Power High: Once she breaks free from Lapis' control as Malachite, she comes to enjoy it immensely.
  • Principles Zealot: If she isn't stalking all across the water for Lapis Lazuli, or trying to get revenge on Rose Quartz for what she's done to her, she's preaching the principles Homeworld has instilled on her since birth, whether people want to listen or not.
  • Proud Warrior Race Girl: She is firmly of the belief that Quartz Gems are made to fight and should live for it, thus why she's a Blood Knight. It's also why she throws a fit whenever she loses to someone she views as inferior to her. She considers Amethyst a disgrace to Quartzes due to her defective status and how poor of a fight she gave her, and "Beta" implies this is especially tempered by the fact she was the only (and in fact most) perfect Gem to emerge from the Beta Kindergarten.
  • Rapunzel Hair: Her hair goes down approximately to her knees and is very voluminous, like all Quartz Gems.
  • Rated M for Manly: Though like all Gems she's sexless and referred to with female pronouns, pretty much everything about her appearance and personality scream of this trope.
  • "The Reason You Suck" Speech: In her battle with Amethyst, Jasper calls her a discrace for being a defective Quartz and wondered how Roze Quartz tolerated her. When Amethyst says back that Rose loved her just as she was, Jasper dismissivly says Rose had low standards before poofing Amethyst.
  • Red Herring: When Malachite defuses, we don't see her face as she falls, suggesting she may have cracked her gem from the defuse shot. Turns out this is not the case when she returns in "Alone at Sea".
  • Redemption Rejection: She completely refuses Steven's attempt to heal her corruption due to her hatred of Rose. Sugar had this to say about Jasper during an interview with the Wrap.
    Jasper is very different than Peridot and Lapis. Unlike them, she has a deep hate for herself because of her origins on Earth. She is determined to never be weak or vulnerable. So at the point when she's the lowest, there's no way she'd ever accept help, because she believes she doesn't deserve it.
  • Rejected Apology: As she's becoming corrupted, Steven tries to apologize for what Rose supposedly did, and even offers to try and heal Jasper while her corruption's on her way. Jasper immediately rejects "Rose Quartz's" apology and offering to help, instead opting to call her out for all the pain "she" made her suffer in her last moments of consciousness.
  • Revenge:
    • She attempts to shatter Steven in retaliation for Lapis rejecting her choice to fuse back into Malachite.
    • She hates Rose Quartz for shattering Pink Diamond and preventing the Earth from being colonized. The irony is, Rose is Pink Diamond.
  • Revenge Before Reason: Jasper is angered by always being defeated by a fusion and desperate to finally make "Rose Quartz" pay for everything she's done during the Rebellion, she fuses with a corrupted Gem ending up causing her own corruption.
  • Rogue Agent: After defusing from Lapis, Jasper went completely rogue, abandoning her mission and not even attempting to contact Homeworld nor the agents sent to look out for her.
  • Rolling Attack: Uses a similar version to Amethyst's, only with a Battle Aura.
  • Running Gag: Every time she appears, Steven (and sometimes another character) says her name in surprise.
  • Sanity Slippage:
    • If her appearance in Malachite's mindscape in "Chille Tid" is any indication, any stability Jasper had left seems to be eroding under her imprisonment by Lapis.
    • In "Alone At Sea", she has become obsessed with fusion, begging Lapis to become Malachite with her again.
    • She seemed to actually be getting better in "Gem Hunt" and "Crack The Whip", forming a coherent plan and pursuing some objective.
    • Unfortunately for her, she ultimately totally loses it in "Earthlings" after trying to fuse with a corrupted Gem during her fight with Smoky Quartz. Steven not knowing about what Rose did to Pink Diamond is the final push that turns her into a mindless corrupted Gem herself.
  • Sealed Evil in a Duel: Lapis fuses with her and traps them both under the ocean in a constant Battle in the Center of the Mind.
  • Shadow Archetype: To Rose Quartz. Rose Quartz is a crystalline quartz, Jasper is a non-crystalline quartz. Rose used her defensive weapon, a shield, to defend herself and her allies; Jasper uses her Cool Helmet, usually a defensive weapon, offensively, charging and headbutting enemies. Rose was a Friend to All Living Things who devoted her life to defending and protecting Earth, Jasper is The Social Darwinist who sees no value in Earth.
  • Shut Up, Kirk!: Jasper refuses Steven's help curing her corruption, thinking that Rose Quartz is trying to prey on her weakness like all her other misfit recruits.
  • A Sinister Clue: Jasper is consistently shown to be left-handed.
  • Sinister Schnoz: She has her gem in the middle of her face in place of a nose.
  • Slasher Smile: If she's not wearing a look of contempt, she's wearing this.
  • Smug Super: She is legitimately powerful even by her Gem type's already impressive standards, and at first wants Peridot to just shoot the Crystal Gems with the ship's main gun because she thinks they're not worth her time.
  • The Social Darwinist: She derides fusion as a tactic for weak Gems, and derides Amethyst as an 'overcooked runt' and Pearl as 'defective'. In "Earthlings", she makes a speech about how Gems who are of no use to the Diamonds should be purged, and believes Gems falling to misfortune such as corruption are getting what they deserve.
  • Sore Loser: As she bases her entire worth on being a warrior, she cannot accept losing. Being defeated by Garnet started her obsession with increasing her personal power with fusion and army building that eventually lead to her downfall.
  • Sparing the Aces: Is notably the one Earthborn Gem that Yellow Diamond took into her court, let alone gave a high ranking and allowed to be seen as a war hero. Given the rest were all Reassigned to Antarctica or bubbled, and solely because Blue Diamond wanted to keep them, this implies Yellow Diamond valued a completely perfect and extremely rare 'ultimate Quartz' enough to overlook her hatred of Earth and everything that came from it.
  • Springtime for Hitler: Heavily implied. Jasper's birthplace, the Beta Kindergarten, was an utter hash job that produced many inferior gems, which was almost certainly done on purpose by Pink Diamond, who wanted the war against Rose's Rebellion to fail. By some fluke, Jasper emerged as a top-quality quartz anyways.
  • Stalker Without a Crush: Started tracking Lapis down since they de-fused. Once Lapis makes it clear she's not interested, Jasper leaves her alone and focuses on "Rose" instead.
  • Stockholm Syndrome: After her hellish experience imprisoned under the ocean for months, upon being freed she's obsessed with fusing back with Lapis.
  • Strength Equals Worthiness: As indicated by Rebecca Sugar herself, Jasper never wants to show weakness.
  • Super Soldier: "Beta" reveals that she's far more advanced than Quartz soldiers usually are, despite coming from a shoddily-made batch of gems. Peridot goes so far as to call her "the ultimate Quartz".
  • Super Strength: She is stronger than Garnet and shatters pieces of Peridot's ship with her blows.
  • Symbolic Mutilation: When she is corrupted, her eyes are painfully covered, blinding her.
  • Technicolor Eyes: While most characters on the show have simple eyes with no distinction between pupil and iris, Jasper has more detailed, piercing yellow eyes that the storyboarders seem to like to zoom in on.
  • Teeth-Clenched Teamwork: Jasper's personality leaves a lot to be desired, and both Lapis and Peridot are vocally annoyed about having to work with her.
  • There's No Place Like Home: Jasper has a dark form of homesickness for Earth. She was created there for the sake of putting down the Rebellion, and thus viewed war in the name of destructive colonization as Fighting for a Homeland. Then Homeworld abandoned all plans for colonizing Earth, instead intending to destroy it. Now Jasper still considers Earth to be "[her] planet", but despises it because it will never be what she wanted it to be—what she was born to make it.
  • This Cannot Be!: Doesn't take losing to Garnet well at all, trying to rationalize it that she only lost because Garnet was a fusion. This extends to Stevonnie and Smoky Quartz.
  • Tomboyish Name: Like every other Gem, she's named for a type of jewel, but Jasper is also a male given name (whose etymology is actually unrelated to the stonenote ).
  • Tomboy with a Girly Streak: When she fuses with Lapis, she dances in a manner reminiscent of ballroom dancing.
  • Tragic Villain: At the end of "Earthlings", we can see Jasper is essentially another victim of the Diamonds' cruel regime: she is created for one purpose (to fight) and incapable of believing she's anything but a soldier for them. Despite her status as the 'perfect' specimen and mocking of Amethyst, Amethyst is strong because of those she loves standing with her while Jasper is alone and incredibly lonely. And her inability to believe in Steven's kindness and her insane devotion to the Diamonds results in her corruption and bubbling.
    • Even more tragic when you consider she's The Lost Lenore, and misses Pink Diamond very badly, utterly despising Rose for taking her mistress away from her.
    • Absolutely tragic since Rose IS Pink Diamond and had no possible way of knowing. Jasper is the "ultimate Quartz" that Homeworld admires and strives for in Gem-making. But Pink (in the guise of Rose) regarded Amethyst as her ultimate creation. A Gem free to live her life on Earth, free from having to know about her origins, Homeworld, or the terrible war.
  • Tranquil Fury: After Peridot tells her that she's a Crystal Gem, she shows very little expression, but her summoning her weapon makes it clear that she would've attacked her if she hadn't gotten sidetracked by Steven and Amethyst.
  • Tyke Bomb: While Gems are physically Born as an Adult, she was essentially born fighting a war... and her personality reflects this.

     U to Y 
  • Ultimate Life Form: When we see the hole she came out of, it's enormous; Peridot inspects it and says that it's the most perfect exit hole she's ever seen, concluding that Jasper's "the ultimate Quartz". Stories about Quartz soldiers during the war and the fact she seems more powerful than a Topaz (which are explicitly higher ranked than she is) imply this comes with being way stronger than a normal Quartz has any right to be.
  • Undying Loyalty: She was originally made for Pink Diamond, and remains devoted to avenging her thousands of years after her death.
  • Use Your Head: Since her weapon is a helmet, she just headbutts everything in her way.
  • Vile Villain, Saccharine Show: While in terms of reprehensible behavior, she's about even with Lapis and Peridot, unlike them, Jasper has so far not shown any comedic traits, nor any sympathetic attitudes, making her stand out compared to the other members of the 'Homeworld trio'.
  • Villain: Exit, Stage Left:
    • In "Gem Hunt", once Jasper has the two poofed Gems, she exits without fighting Pearl, Steven, and Connie.
    • In "Crack the Whip", she retreats into the ocean when it becomes apparent Stevonnie is a tougher adversary than she thought.
  • Villainous Breakdown: She has an epic one just before she turns into a Gem Monster; she realizes that Steven, whom she thought was Rose in a new form this entire time, has no clue who Pink Diamond is. This revelation was bad enough that it made her completely lose her grasp on sanity and turn into a Gem Monster proper.
  • Villainous Rescue: In "Gem Hunt", she rescues Steven and Connie from a Gem monster, but only did so to claim the gem from the monster for her plan to build her own Gem army.
  • Villainous Virtues: As awful and monstrous a person she is, one thing can't be taken away from her: she's determined. And loyal to the end, as she was for Pink Diamond.
  • Villain with Good Publicity: She is apparently seen as a big war hero back on Homeworld.
  • Visual Pun: She's both hard-headed and hard-nosed.
  • Wake-Up Call Boss:
    • She easily lays waste to the Gems the moment she arrives on Earth, even poofing Garnet. She's also the first threat that wakes Steven up to the real dangers of Gem stuff and shows him that he can't expect to redeem opponents so easily.
    • Amethyst learns the hard way that she can't keep relying on being Unskilled, but Strong after being pummeled and nearly shattered by Jasper.
  • Walking Spoiler: In the same vein as Peridot and Lapis.
  • Weapon of Choice: She uses a helmet to bash enemies with her own head. Jasper is a warrior who prefers to charge at any obstical head on and overpower it.
  • We Can Rule Together: She offers Lapis a chance to get revenge on the Crystal Gems by fusing with her. Lapis accepts and then uses the chance to chain and imprison them both as Malachite beneath the ocean.
  • Where I Was Born and Razed: Her dismissive comments of Earth become a lot more disturbing with the reveal she was born there.
  • White Hair, Black Heart: Her hair is beige, but it looks white on certain coloring, and she's a true unhinged psychopath.
  • Wild Card: Despite remaining loyal to Homeworld, Jasper's willingness to act on personal impulses and growing instability makes her goals hard to predict.
  • With Great Power Comes Great Insanity: She was already pretty unstable, what with being the perfect Quartz and the insanely high expectations such status brought, but any sort of stability or sanity left in Jasper completely vanished the moment Malachite happened...
  • Worthy Opponent:
    • Although on opposing sides she respects Rose Quartz as a military commander and accompanied Peridot on the off chance they could battle again. In fact she seems to be the only Gem besides the Diamonds she has any respect for. Though she loses some of this respect after Malachite, especially now that Rose has turned into a "dulled down version".
    • She may see Lapis as this too; when Malachite finally breaks her chains, the first thing Jasper says is, "I'm impressed, you really held out." It turns out to go beyond this and then subverted, with Jasper developing Stockholm Syndrome for Lapis and wanting to be together.
  • Would Hurt a Child: She headbutts Steven to knock him out. Although she had assumed he was Rose, it's doubtful she would have hesitated otherwise; despite that, she still displays sufficiently accurate control and restraint to not kill him, dispelling her helmet before she strikes. Later, she loses interest in taking him alive, outright saying she will have him shattered.
  • Yandere: Subverted. Comes across as this when she tries to rebuild her alliance with Lapis in "Alone At Sea". Granted, once Lapis makes it clear she's not going for it, she drops it completely and goes back to plotting the Crystal Gems' downfall.
