Jasper

"Jasper" is a Gem from Homeworld who first appeared in "The Return". She is currently stuck at the bottom of Earth's ocean alongside Lapis Lazuli as Malachite.

Appearance
Jasper has light tangerine orange skin with darker orange markings on her face along with long, thick white flowing hair similar to Amethyst. Her gemstone is located in the placement of where her nose would be. When Jasper's gemstone is activated, it summons an orange, polygonal, helmet. Jasper also has a muscular frame, an indication of her strength and durability.

Personality
Jasper is very ruthless and arrogant, along with being headstrong and an aggressive combatant. During her arrival on Earth, she looked down upon the Crystal Gems and insulted them relentlessly. But, she proved to be somewhat hypocritical, when she egged Lapis Lazuli to fuse with her so that she could defeat the Crystal Gems.

However, Jasper is also shown to have very prideful/honorable side (both negative and positive) to her personality. When she meets Steven, thinking that he's Rose, she says that she respected Rose's tactics and strategies. Though, her more "arrogant/self reliant" pride is shown when she calls fusion a, "Cheap tactic used by weak gems to make them stronger," as well as when she calls Garnet a "shameless display."

Abilities
Like all Gems, Jasper can shapeshift, summon a weapon, and retreat to her gemstone to regenerate.

Jasper possesses an incredible amount of physical strength, and can take plenty of punishment. When Jasper activates her gemstone, she can summon her weapon, a Crash Helmet that she uses to ram, or headbutt, her opponents, or smash through obstacles. Jasper can fuse with Lapis Lazuli to form Malachite.

Unique Abilities

 * Spin Dash: Being first demonstrated in "Jail Break", 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, as indicated by the aura around her when performing that move. This attack is similar to the popular video game character Sonic the Hedgehog's attack, which is also called the Spin Dash.
 * Comet Charge: Being First demonstrated in "Jail Break", Jasper can lunge at her foes with alarming speed and power as evidenced by the attack breaking through layers of hard gemstone. While she performs this attack an orange comet appears to form around her.  She performs this attack during her fight with Garnet, when she rams her through the floor into the ship's power generator room.

Additional Tools

 * Gem Destabilizer: Modern Gems carry Gem Destabilizers -- extremely potent, "non-lethal" tools used to subdue enemy Gems. When activated, a Gem Destabilizer generates an energy field which destabilizes and destroys a Gem's physical form, forcing the victim to retreat into their gem to regenerate. Another effect is, if used on a Fusion Gem, the Destabilizer causes the fusion to revert to their individual gems. The only one who seems to be immune to its effects is Steven because of his half-human physiology.

Crystal Gems
She thinks they are all a puny excuse for an army and think that they are pathetic and weak.

Rose Quartz/Steven Universe
She highly despises them and wishes to beat their face into the ground for what they have done against rebelling the gems, she thinks of them as traitors to the Homeworld and deserved to be punished. Although she did state that she had respect for Rose's tactics. When she thought Steven was Rose's current form she think it's sick.

Peridot
She thinks little to nothing of Peridot, looking at her like lower class and not prioritizing her complaints or listening to her requests, like a negligent mother to a daughter.

Lapis Lazuli
Jasper was put in-charge of Lapis after she returned to the Gem Homeworld and was forced into helping the Homeworld Gems to defeat and capture the Crystal Gems. Jasper does not seem to care much for her, as she is shown to grab her very roughly and having no problems with imprisoning her after finding out Lapis withheld information from her, Jasper also called Lapis a 'Brat.' Their relationship is like an abusive mother to a daughter. When Jasper tried to manipulate Lapis into fusing with her to stop the Crystal Gems, Lapis consented. The two of them formed Malachite, with Lapis' intent of using her Hydrokinesis to imprison both of them at the bottom of the ocean in order to save Steven.

Garnet
Jasper has a highly negative opinion of Garnet, and thinks she uses "cheap tactics" because she's a fusion. She and Garnet are conflicted as Garnet did throw her into an energy source exploding a Gem Warship causing lots of damage.
