Fighting is my life! It's what I was made for.
|—"Crack the Whip"|
Jasper is a Homeworld Gem and antagonist who made her debut in the episode "The Return". As of "Earthlings", she has become corrupted after fusing with one of the Corrupted Gems that she had held captive. She now resides in the Burning Room in the Temple after being poofed by Peridot and bubbled by Amethyst.
Jasper had tangerine skin with reddish-orange markings on her face and arms. She had amber eyes and plump lips. Her gemstone was located where a normal nose would be. She had thick, beige-white-colored flowing hair. Physique-wise, she was the archetype Quartz Gem soldier; she had a muscular body and stood both taller and wider than Garnet, an indication of her immense strength and durability.
She wore a sleeveless bodysuit, similar to Peridot's, with a dark mahogany V-neck collar and a yellow diamond in the center. The torso of the bodysuit is maroon, and the legs are dark mahogany. She wore red boots with dark red toe caps.
After her corruption, she became similar in body type to the wolf-like Snow Monster she fused with, gaining teal spikes across her body, losing her eyes, and gaining two ram-like horns on the side of her head. Spikes protrude from multiple areas of her body, and she appears to have beige-colored mane/tuft of hair growing around her neck. Blotches of green and orange make up her skin, and her teeth became sharp and orange.
Jasper is ruthless and headstrong, as well as a brutal combatant. Assumed to be a high-ranking Gem soldier and veteran of the Rebellion, Jasper is very authoritative and militaristic which directly affected her former subordinates, Peridot, and Lapis Lazuli. She does not care about them, does not bother to heed their warnings or concerns, and will not hesitate to browbeat them into submission if they complain or disagree with her. The prejudice that Jasper exercises based on combat experience leads her to look down upon beings that appear weaker to her.
Her attitude towards those whom she considers having proven themselves in battle, however, is a much more positive and respectful one. When she first arrives on Earth, she quickly dismisses Garnet, Amethyst, and Pearl as weaklings not worth her time. She did, however, express disappointment after finding out that Rose Quartz was not present because she wants to face her in battle, as she respects her as the military commander of the Crystal Gems. Likewise, this causes her to be confused and frustrated as to why Rose apparently shape-shifted into a human boy to fight.
In "Chille Tid", Jasper appears furious and unhinged. The most probable reason being the extended period that Jasper has remained immobile, trapped with Lapis in a seemingly endless power struggle in Malachite, held down with the weight of Earth's ocean and unable to escape the fusion. She is also shown to have developed a hatred towards Steven, attempting to attack him until Lapis gains control.
She initially possessed a disdain for the act of fusion, claiming that it was "just a cheap tactic to make weak Gems stronger!" When Garnet defeated her and crashed the Gem Warship, the prospect of a humiliating defeat at the hands of the Crystal Gems revolted her so much that, in a desperate and hypocritical attempt to seize victory, she compelled Lapis Lazuli to fuse with her to form the unstable fusion Malachite. The two became trapped in a single body for an extended duration, and in that time Jasper became addicted to the massive increase in combat strength that fusion supplies; in "Super Watermelon Island", Jasper's personality spoke through Malachite, declaring that there was "more to this fusion thing" and that it opened her mind to a new world of possibilities. Presently, she is in an unfused state, but her stance on Fusion has completely turned to one of total approval, albeit for perverse reasons, which eventually lead to her corruption after fusing with the green Snow Monster. However, despite her change in views on fusion, in "Crack the Whip", she is shown to be repulsed by Steven and Connie's fusion Stevonnie, due to them being a fusion between a Gem and a human.
At the expense of all else, Jasper's mindset on victory is her primary focus. Without the prospect of a challenge, she considers the task at hand a waste of time. Jasper will even forsake her beliefs if that means she will come out on top. Interestingly, as long as they fought on even terms Jasper does seem to respect those who best her in combat, implying she has a warped code of honor.
In "Alone at Sea", while still being as cruel and ruthless as before, Jasper appears more pathetic than in the past, with various attempts to convince Lapis that she has changed to take her back. Jasper also appears much more unhinged and unstable, having become completely addicted to being Malachite and the power they possessed together. After Lapis refuses to fuse with her again, she scornfully blames Steven, going as far as attempting to shatter him.
In "Gem Hunt", Jasper is shown to be ruthless and carefree about injuring and poofing Corrupted Gems. Jasper even forcefully pulls the gemstone out from one of the monsters' body, showing no remorse afterwards. The reason for this is explained later in Earthlings when she states to one of the Corrupted Gems "you suffer because it's what you deserve!". Jasper believes this because the Corrupted Gems are weak, pathetic versions of their former selves, and now they embarrass Homeworld.
In "Crack the Whip", Jasper reveals that she has enslaved the Gem monsters that she retrieved at the Great North to create her own personal army. She is shown to be somewhat sadistic, as while fighting Amethyst, Jasper shows no regards for her feelings as being defective and appearing to take delight in seeing her suffer. Jasper believes Amethyst is not a true Quartz soldier, telling her it is why she is so weak. Jasper even insults Rose Quartz's standards, knowing that it would enrage Amethyst. When one of the monsters became injured in battle from Lion's attack, the monster tried to flee, but Jasper did not let her, grabbing her tail and flinging her back to herself. She is also shown to possess a willingness to kill as she was about to finish off Amethyst by destroying her gemstone, but was stopped due to Stevonnie's intervention.
In "Earthlings", Jasper has been shown to have no respect for any Gem that does not maintain their role in worshiping the Diamonds. She also seems to hold her herself in high regard, believing herself to be better than Earth. It is also revealed that Jasper's hatred toward Steven (and by extension, Rose) is because of what Rose did to her Gem colony, her planet, and Pink Diamond, making her seek revenge, which is the reason she returned to Earth to fight the Crystal Gems. It is hinted she harbors a bit of sorrow because of the loss of her Diamond as well. She also seemed upset that no-one she has ever fused with (Lapis and the Gem monster) liked fusing/being with her, showing a somewhat insecure side. It is also hinted in "Earthlings" that she considers herself somewhat of a failure due to the shattering of Pink Diamond,
I see how you do it now Rose. You want gems after they're worthless, you wait until after they've lost. Because when you're at the bottom... you'll follow anyone who makes you feel like... less of a failure...
When asked why Jasper, unlike Peridot and Lapis, refused help from Steven, Rebecca Sugar says:
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.
Peridot and Lapis both believed they deserved better than what happened to them, but not Jasper. She went back to Earth to face her demons, and she lost. She’s consumed by her own self pity.
All Era-1 Gems have various powers, including the ability to invoke a weapon, change shape, and strength, agility, speed, and skill beyond human capabilities. Jasper can also take refuge in her gemstone after being wounded to heal. She is also capable of fusion, as shown when she fuses with Lapis Lazuli to form Malachite and later a corrupted Gem to form a centaur-like monstrosity.
Being a Quartz Gem, her creation was to fit the role of a soldier within Gem culture. According to Peridot (a certified Kindergartener skilled enough to identify the type of Gem that emerged from a particular exit hole with a glance), Jasper is the 'ultimate' Quartz, made completely perfect, implying she is a superior specimen even among her own kind. As such, she has incredible amounts of physical strength and stamina, making her one of the most physically imposing Gems seen thus far. She is also strong of will, as it takes all of Lapis' concentration to subdue Jasper. Jasper's strength is further emphasized in "Alone at Sea" when she climbs up the anchor chain on the side of the ship, making the entire ship shake and creating a loud thumping sound. This happens once more when Jasper steps onto the ship.
Jasper is also one of the most durable Gems ever shown in the series, being capable of withstanding the point blank explosion of a Gem Warship's reactor, the following crash and explosion of the entire ship unprotected, being hit with enough force to send her flying over the horizon, and being struck with enough force by Rose Quartz's Sword (which has the power to easily destroy a Gems' physical body) to be driven through a Corrupted Gem (poofing it in the process), all without poofing once. It takes Peridot driving a piece of scrap metal clear through her chest and out her back to finally poof her, and even then that was only after she had been corrupted.
- When fused with Lapis Lazuli, they form Malachite.
- When fused with the Snow Monster, they form a Corrupted Jasper Fusion.
- Crash Helmet Proficiency: By gathering her resolve and thirst for battle, Jasper can summon her weapon; a tangerine, crystalline helmet. The helmet acts both as a weapon and armor; a hammer-like protrusion in the front of the helmet allows her to use it to charge, slam, and headbutt her opponent, in the shape of a yellow diamond, while a clear orange-tinted visor extends down, covering the upper part of her face and her gemstone. The sturdiness of the helmet rivals that of Garnet's gauntlets, as Jasper was shown continuously countering her attacks. A fast swing from the front of the helmet was hard enough to poof Amethyst (among other damage she had). Its usefulness as armor is shown when she is struck with an extremely powerful blow from Stevonnie using Rose Quartz's sword that would have gone directly into her head without it. While the Corrupted Gem Jasper was riding is poofed from the force of the strike slamming Jasper into her, Jasper was not.
- Martial Arts: Further reflecting the similarities between herself and Amethyst, Jasper is likewise prone to mixing up her weapon-based attacks with martial arts moves, such as grappling, throwing, or attacking with swift yet powerful punches. Due to the nature of her weapon, the two styles mix seamlessly and combine into a powerful, but ultimately reckless fighting style with immense collateral damage. She is also skilled enough to completely outclass Amethyst.
- Headbutting: As the name implies, Jasper shows she can headbutt without her weapon. This version, although weaker without her helmet, still has the potential to knock out a human being, as seen with Steven in "The Return".
- Comet Charge: Jasper can lunge at her foes with alarming speed and power. Evidence shows as the attack breaks through layers of a hard gemstone. While she performs this attack, a fiery aura forms around her.
- Spin Dash: Jasper can rapidly roll in a ball-like shape to attack enemies. While Amethyst was shown to have this ability as well, it seems that Jasper's version is more powerful, and is more of a threat than Amethyst's. Jasper can also use the technique to dash across a spacious room and plunge into the air.
- Gem Destabilizer: Homeworld Gems, in addition to their summonable weapon, seem to carry a personal defense weapon known as Gem Destabilizers — extremely potent, non-lethal tools used to subdue enemy Gems. Jasper is seen using this weapon on Garnet in "The Return". She attempts to use it again in "Jail Break", but Garnet pried it from her hand and broke it immediately afterward.
Help..? Help?! I've been fighting from the second I broke free of the Earth's Crust, because of what YOU did to my colony! Because of what YOU did to my PLANET! Because of what YOU did to my DIAMOND!
Jasper holds strong animosity towards Rose, due to her being the one who shattered Pink Diamond. She accepted the mission to escort Peridot on Earth because she was looking forward to beating Rose "into the ground" in order to avenge her Diamond. Despite this, Jasper expresses a great deal of respect towards Rose for her role as the military commander of the war, although she does harbor disgust towards Rose's love for the Earth and will to fight for the planet. Jasper believes that Steven is Rose, and treats him as such.
In "Chille Tid", Jasper is shown to harbor a vendetta against Steven and tries to attack him upon seeing him. However, Lapis manages to restrain and suppress Jasper.
In "Super Watermelon Island", Jasper's personality through Malachite shows that she bears an animosity towards Steven, even referring to him by name instead of Rose (though it is likely Lapis' connection within before Jasper steals back control), to the point where the Watermelon Steven's resemblance of him angers her. However, while Steven and Jasper have by no means a friendly relationship, he did call out to her when she fell into a crack in the earth, apparently valuing her life nonetheless.
In "Alone at Sea", Jasper is still unaware that Steven and Rose are not the same, referring to him as "a dulled down version of Rose Quartz". Despite her dislike for him, she does not attempt to harm him until Lapis rejects her pleas to reform Malachite. When Steven continues to defend Lapis, Jasper blames Steven, charging at him in an attempt to shatter him before Lapis intervenes.
In "Crack the Whip", Jasper insulted Rose for having a defective Quartz like Amethyst and stated she must have low standards when Amethyst counters by saying that Rose thought that Amethyst was perfect the way she is.
In "Earthlings", Steven finally tells Jasper his name, though she continues to refer to him as Rose. Jasper refuses Steven's help when he tries to heal her corruption because she comes to her own conclusion that Rose takes advantage of weakened or defective Gems like Amethyst. Feeling that by feigning concern for Gems will convince them to follow her, Jasper believes that Rose's compassionate nature (and Steven's by extension) is a facade. Enraged, Jasper screams at Steven that she's been fighting her entire life because of what Rose did to her colony, her planet, and Pink Diamond. Jasper also reveals that she came back to Earth to defeat Rose because of what she did to Pink Diamond.
You Crystal Gems would even fuse with a human!?
|—"Crack the Whip"|
In "Crack the Whip", Jasper is shown to be visibly disgusted when Steven fuses with the human Connie to rescue Amethyst, who Jasper had just defeated. As with Steven, Jasper refers to Stevonnie as Rose (likely due to the fact that they use Rose's weapons and possess her gemstone). When Stevonnie manages to put up a decent fight, Jasper expresses frustration at once again having difficulty fighting a fusion and retreats back into the ocean, swearing revenge.
Is fusion the only trick you Crystal Gems know?!
Upon first seeing Smoky Quartz, Jasper commented that fusion was the only tactic the Crystal Gems had. After realizing she could not win against them, she exclaimed that she would not lose against yet another fusion. Ironically, this incited her to fuse with a Corrupted Gem, which ultimately leads to her own corruption.
You don't need me for this. Just blast them with the ship.
Due to the Crystal Gems being traitors who staged a rebellion against their Homeworld, and the fact that Jasper fought on the side of the loyalist Gems in the conflict, her view on the Crystal Gems is naturally a negative one. She is eager to settle the score with them; so much so that she expresses disappointment in the fact that the only ones left from Rose's army are the Crystal Gems. She initially considers them unworthy for her to fight personally and simply orders Peridot to blast them with the Gem Warship.
Jasper appears to do whatever she can to get even with the Crystal Gems for everything they have done, such as stopping the Earth's colonization. Some of Jasper's actions to end the Crystal Gems' existence involved imprisoning them in order to take them to Yellow Diamond, forming Malachite to shatter them, and creating her own army of Corrupted Gems to compete with the Gems.
In "Super Watermelon Island", she takes control of Malachite to 'have some fun' and destroy the Crystal Gems, who have fused as Alexandrite. During the fight, she uncharacteristically thanks the Crystal Gems for proving her previous opinion wrong - that fusion is not just some cheap trick. To 'thank' them, she attempts to unfuse Alexandrite by squeezing her with hands created by water and freezing them, as she sees there is room for only 'one abomination'.
Oh great, you're both out? And you're fused again? Why? Fusion is just a cheap tactic to make weak Gems stronger. Quit embarrassing yourselves! I've seen what you really are.
Jasper and Garnet's relationship is very antagonistic, as Jasper's self-reliant outlook on life means that she looks down on Garnet for being a fusion. When she first meets Garnet, she refers to her as a "shameless display", implying she knew that Garnet was a fusion. Her defeat at the hands of Garnet in a rematch pushes her to make the hypocritical decision to fuse with Lapis in an attempt to become stronger. This rash decision led to her confinement at the bottom of the ocean until "Super Watermelon Island".
You're a quartz soldier just like me. But you're not like me... are you?
|—"Crack the Whip"|
Jasper quickly recognized that Amethyst is a Quartz Gem soldier much like herself, only an "overcooked runt", indicating that despite their shared heritage, she sees Amethyst as just another Crystal Gem rebel, and perhaps an inferior version of herself. In "Crack the Whip", she belittles and insults Amethyst over her inferiority, claiming that Rose must have low standards when Amethyst argued that Rose said she was perfect the way she is, which caused Amethyst to attack her in anger only to be defeated and poofed. Jasper then attempts to kill Amethyst by crushing her gemstone, forcing Steven and Connie to fuse into Stevonnie to rescue her, which shows that Jasper is willing to kill Amethyst. She also commented that if Amethyst was not defective, she could have been like Jasper herself. Despite being saved and regenerated, Amethyst is affected negatively by her defeat and the fact that Steven and Connie managed to ward off Jasper without her help, causing her to question her usefulness, having apparently taken Jasper's comments about her to heart. As of "Beta", Amethyst still holds a grudge against Jasper and trains extensively for a rematch against her, much to Steven's concern. In "Earthlings", with some encouragement from Steven, Amethyst finally overcomes her feelings of worthlessness and forms Smoky Quartz with him in an attempt to defeat Jasper once and for all. After Jasper was corrupted following her fusion with the Snow Monster and poofed by Peridot, Amethyst seems to take pity on Jasper and even refers to her as "Sis" (as they are both Quartz gems that were made on Earth) as she bubbled her gem.
Some lost, defective Pearl.
|—Jasper, "The Return"|
Jasper has almost no respect for Pearl, both as a rebel and a perceived servant. Because Homeworld Pearls form a servant class and usually answer to a higher-ranking Gem, Jasper nonchalantly referred to her as lost and defective.
"How can you side with Rose Quartz?! Why? Why protect this useless shell of a planet?"
"It's not a shell. There's so much life, living here. That's what I'm doing! I'm living here! I've been learning new things about myself all the time! Like how I can make metal do my bidding! The point being: Earth can set you free."
|—Jasper and Peridot, "Earthlings"|
Jasper and Peridot seem to hold some tension between each other. Most of this seems to stem from the fact that Jasper is put in charge of escorting Peridot, as the Crystal Gems repeatedly hinder Peridot's efforts, forcing Peridot to report to her superior(s) and ask for additional help in the matter. Jasper pays little attention to Peridot's grievances and complaints, possibly as a result of Jasper looking down on Peridot, who is more of an intellectual/technician than a soldier. Peridot states in a message intended for Yellow Diamond that Jasper was her escort, though the Rubies sent by Yellow Diamond later clarified that Jasper was acting leader of the mission to Earth. In "Earthlings", Jasper seemed surprised to find that Peridot has joined the Crystal Gems, and no longer serves Homeworld.
I thought I was a brute, but you, you're a monster!
|—Jasper, "Alone at Sea"|
Jasper was put in charge of overseeing Lapis, following her return to Homeworld. After imprisoning her, she forces Lapis into being hers and Peridot's informant as a way to help them find and capture the Crystal Gems. Jasper treats Lapis very roughly and sends her back to her cell after finding out she withheld information from her, despite Lapis saying it is not relevant to the mission. When Jasper attempts to coerce Lapis into fusing with her to defeat the Crystal Gems, Lapis eventually agrees. The two fuse together to form Malachite, with Jasper initially appearing to be the dominant personality. Before Jasper can make use of her new form, Lapis regains control of her hydrokinetic ability to bind and imprison their fusion beneath the ocean. While trapped beneath the ocean, Jasper is tenacious in her efforts to either regain control of Malachite or escape the fusion. They are later unfused in "Super Watermelon Island" after being defeated by Alexandrite.
In "Alone at Sea", Jasper begs Lapis to re-fuse with her, claiming they were better together than apart. She claims that Lapis is a monster, and only she could handle that power. Jasper appears sycophantic, claiming that she has changed. After being rejected, she became enraged and attempted to "shatter" Steven until she was thrown back into the ocean by Lapis.
As a Homeworld soldier, Jasper answers to Yellow Diamond but is not too loyal to her. While she strongly values and believes in the Diamond Authority, she is not as loyal as she could be. She easily disregards her primary mission of checking on the cluster and goes off doing her own thing. Implying that while she answers to Yellow Diamond, she does not consider her as her true leader. Which could be a reason as to why she still refers to Pink Diamond as her Diamond. Upon mistaking Steven for Rose Quartz, Jasper immediately ordered Steven to be captured and brought before Yellow Diamond. Their personal relationship is unknown, although in "Message Received" Yellow Diamond seemed less concerned about her than the ship she was on and in "Hit the Diamond", Yellow Diamond sent a team of Rubies to find and retrieve Jasper.
Not much is known about the relationship between Jasper and Pink Diamond, though from Jasper's ideology, shows that she had a great deal of respect for her as she served under her. This respect continued as Jasper is still angered towards Rose Quartz for what she did to her former leader. Jasper continues to refer to Pink Diamond as her Diamond even after she was shattered, showing how much adoration she had for her.
It is not known if Jasper has met Eyeball, but it is shown in "Back to the Moon" that Eyeball looks up to Jasper as she is flattered when Amethyst (disguised as Jasper) tells her to write her report for her on Homeworld.

- Jasper had a yellow diamond on her uniform, just like Peridot.
- It is later revealed that she actively served one of The Great Diamond Authority's members, Yellow Diamond, prior to being corrupted.
- She formerly served Pink Diamond.
- Jasper can be considered an opposing counterpart to Rose Quartz.
- Rose and Jasper both have the same hair length, but while Rose's hair is soft and curly, Jasper's hair is wild and unkempt.
- Rose wears a dress while Jasper wears a body suit.
- They both are of similar height and stature, with Jasper being more muscular than Rose, indicative of both of their respective natures.
- Rose's combat style apparently focuses on defense, while Jasper's focuses on offense.
- Rose is kind and serene; Jasper is savage and ill-tempered.
- Rose fought against the Gem Homeworld while Jasper fought on its behalf.
- Both are former servants of Pink Diamond, while Rose is a traitor, Jasper remained loyal.
- This could be a hint to actual mineralogy as jasper and quartz have the same chemical composition (silicon dioxide, colored by iron), but different internal structure.
- Sonic the Hedgehog's Spin Dash is likely to have been the inspiration for the attack of the same name performed by both Jasper and Amethyst.
- Jasper is consistently shown to be left-handed.
- Amethyst and Jasper have similarities in body and combat style due to both of them being made on Earth. These similarities include:
- Jasper and Amethyst both have wild and unkempt hair.
- Both share voluminous lips.
- Jasper can also rapidly roll into a ball-like shape to attack enemies. While Amethyst was shown to have this ability as well, Jasper's version is more powerful.
- This could be a hint to actual mineralogy, as Jasper is a non-crystalline quartz, while Amethyst is a crystalline quartz.
- According to Peridot in "Too Far", Amethyst should be around Jasper's height, but she was made defective. This was also said during "Crack the Whip", where Jasper demeans Amethyst for being small.
- Jasper is the one of the Gems whose outfit changed without her regenerating,(others: Garnet, Pearl, and Amethyst in Beach Party) as seen with the difference between "The Return" and "Jail Break".
- The bands or stripes on Jasper's body are an aesthetic meant to represent the appearance of her gemstone in real life and to give her a camouflage or army commando look that fits her character.
- According to Peridot, the Kindergarten on Earth produced quartz. Because of this, it is possible that Jasper's creation was in the Kindergarten as she is, like Amethyst, a type of quartz.
- This is confirmed in "Beta", with Jasper having been made in the Beta Kindergarten as part of a desperate attempt to crank out cannon fodder to fight in the Rebellion.
- Her helmet resembles a Bōsōzoku's hairstyle.
- According to the Rubies in "Hit the Diamond", Jasper was the leader of Peridot's mission to Earth.
- As of "Crack the Whip", Jasper appears to have taken residence in the ocean outside of Beach City, probably due to having been imprisoned there in months while fused as Malachite.
- As of "Beta", Jasper has been shown to have been living in the Beta Kindergarten with her army of corrupted gems.
- Jasper has been involved in the poofing of three Crystal Gems, more than any other Gem.
- Ruby and Sapphire in "The Return" and Amethyst in "Crack the Whip".
- In "Beta", Peridot describes Jasper as the perfect/ultimate Quartz, stating that she's "never seen an exit hole this perfect."
- As of "Earthlings" she has become corrupted and bubbled.
- She is the first Gem to be seen corrupted on-screen, as well as the first Gem to fuse with a Corrupted Gem.
- She is the Gem that confirms that Pink Diamond existed at some point, that both she and Rose served under her, and claims that Rose is responsible for whatever happened to her.
- A detail confirmed that she was not 100% made for Yellow Diamond, because she refers to Yellow Diamond by her normal name, instead of "My Diamond" like other followers.
- It is implied that Jasper knows how to pilot a Roaming Eye.
- Prior to "Earthlings", Jasper was the longest recurring Gem antagonist who had not been caught and poofed by the Crystal Gems, the second being Peridot, though the latter reformed.
- Ironically, Peridot was the one who poofed her in the end.
- Jasper's corrupted form is reminiscent of orbicular jasper.
- Due to the spikes and size, Jasper's corrupted form resembles the DC character Doomsday.
- This can also be seen as one of the parallels to the 2013 version of General Zod. This includes how they were both born/made to be warriors (Zod was a member of the Kryptonian Military Guild while Jasper is a Quartz, a type of Gem made to be a warrior), having a strong loyalty to their races and home planets, having a mindset that is arrogant, ruthless, violent, wrathful, having a degree of respect for their opponent (Jor-El and Rose Quartz) while being enemies with their opponents' sons and were eventually mutated into monstrous creatures that were defeated by being impaled.
- She is voiced by Kimberly Brooks, who also (ironically) voiced the freedom fighter Daisy Fitzroy in Bioshock: Infinite.
- For an as of yet unknown reason, compared to the other corrupted Jaspers seen in Gem Hunt and Earthlings, Jasper is the only Jasper-type Gem whose gemstone is not octagonal, but rather a three-faceted diamond-esque shape.
- Jasper is the zodiacal stone for Aries, Leo, Virgo, and Scorpio. It is a planetary stone for Mars and is associated with the element of fire, as well as being a secondary birthstone of March.
- Jasper often represents protection, nurturing, relaxation, and so on.
- This is ironic, due to Jasper's cruel and aggressive nature. However, it can also represent fire, a nod to her fiery temper.
- Jasper is a variety of quartz with a chemical composition composed primarily of silicon dioxide.
- Up to 20% percent of fine, dense jasper can be composed of foreign materials, typically hematite, pyrolusite, clay, or calcite.
- Jasper has a microcrystalline structure which means its trigonal crystals can only be seen under high magnification.
- Jasper comes in all colors, mostly striped, spotted, or flamed.
- Jasper herself has multiple markings across her body, a reference to this.
- A variety of trade names specify colors, appearance, or composition. There is no recommendation for color, although red, caused by traces of iron oxide, is one of the most common colors.
- Brown and yellow are also commonly occurring colors for Jasper.
- The name "Jasper" is derived from the Greek word for "spotted stone", referring to its typical multicolored, striped, spotted, or flamed appearance.
|Jasper's gemstone is located where her nose otherwise would be. It is triangular, and faceted onto a low point. It has a diamond-esque shape. As seen in Earthlings, Jasper's gemstone is flat on the other side.|
