Alexandrite

"We don't have to fight! You're outnumbered."

Alexandrite is the fusion of Ruby, Sapphire, Amethyst, and Pearl. She made her debut in "Fusion Cuisine".

Appearance
Alexandrite is a massive fusion with bright magenta skin and six arms. Her eyes are covered by a dark-indigo visor. Instead of a third eye, like Garnet has, she has an alexandrite gemstone, representing the location of Pearl's gemstone, with three dark-indigo oval-shaped lenses surrounding it. Alexandrite's primary face has a structure similar to Pearl's and plump lips like Amethyst and Garnet. This face functions as a mask, covering a second monstrous mouth that has sharp teeth and a long tongue. Both mouths are capable of speech.

Alexandrite's thick, turquoise hair is a collision of all the Crystal Gems' hairstyles. The length and wildness of her hair resemble Amethyst's, the top tuft of her hair is styled to a point to resemble Pearl's, the fullness of her hair resembles Ruby's, and the color resembles Sapphire's.

Pre-regeneration (debut)
Alexandrite's attire was a combination of the Crystal Gems' clothing: The teal bodysuit with a four-pointed star cutout on each knee resemble Amethyst's, the flats and large, dark-mauve shoulder plates resemble Garnet's, and the dark pink belt resembles Pearl's. The gloves on each pair of arms were the skin tone of her three constituent Gems (Lilac for Amethyst, dark magenta for Garnet, and aqua for Pearl). She appears to have a diamond-like cutout on her chest resembling the pink diamond on Pearl's Space Suit. (Pearl/Designs)

Post-regeneration (previous)
In "Super Watermelon Island", Alexandrite's attire underwent changes due to Garnet and Amethyst's regenerations in "Jail Break" and "Reformed" respectively. Her lowest arms are now located on her waist similar to that of Sardonyx, featuring gloves that cut off at her elbows instead of covering the entirety of the two arms. She now wears a dark teal leotard with an enlarged dark magenta sash similar to that of Sardonyx. Her leggings are dark indigo with lilac four-pointed star cutouts, resembling Amethyst's. The diamond cutout on her chest appears to be shorter and has changed color, due to the slight change in hue for Alexandrite's skin tone.

Current regeneration
After Amethyst's regeneration in "Crack the Whip", Alexandrite's attire changes once again in her appearance in "I Am My Mom". The colors of her shoulder pads and collar have switched and are now dark indigo and white respectively, with the collar having a slight tear on one end. Her legging cutouts are now dark teal.

Personality
"Alexandrite is an incredible force on the battlefield. When Pearl, Amethyst and I fuse together with a singular goal, we are unstoppable. But when the singular goal is a dinner party with a human family, we are very confused, and we are very confusing, and we are very sorry." Alexandrite starts off cold, somewhat distant, intense, and sloppy. During "Fusion Cuisine", she is shown not to have a distinct personality, instead displaying the three separate personalities of Pearl, Amethyst, and Garnet. These personalities can exist at the same time and often come into conflict with each other, which may cause Alexandrite to de-fuse. Also, they typically become more prominent as the fusion becomes more unstable, showing Pearl's fear of food, Amethyst's hunger and argumentative personality, and Garnet's social awkwardness, leadership, and control of situations. For example:

"Amethyst: I'm hungry. Pearl: I don't think so. Garnet: Cut it out, you two."

As shown in "Super Watermelon Island", she can keep herself together when in serious situations. She is a ferocious fighter, roaring in a bestial-like manner before charging at her enemy. However, she offers to settle things peacefully before the battle, reminding her enemy that they do not have to fight.

"Fusion Cuisine"
"Steven, are you kidding me?! What is this thing that you have brought to dinner?! It—It's my family. It's all the Gems fused together into a six-armed... giant woman." After an awkward phone conversation between Dr. Maheswaran and Garnet (who pretends to be Steven's mom), Connie’s parents wish to meet Steven’s parents for dinner. While Steven has a dad, he has three "moms", and he does not wish to leave any of them out.

Steven comes up with the idea of fusing the other three Crystal Gems into one Gem that can represent his mom in his nuclear family. After some initial hesitation, they reluctantly agree to go through with it. Fused together as the enormous Alexandrite, the Gems walk to their dinner, where the Maheswarans are impatiently waiting. Greg and Steven have trouble fabricating answers to all of the Maheswarans's questions. Once the food is served, Alexandrite has an internal struggle between the Gems to eat or not eat which causes them to fall out of sync and de-fuse, surprising Connie's parents.

Alexandrite then shows up for a final time when the Gems fuse off-screen to track down the runaway Steven and Connie. She is last seen chasing down and picking up the bus the two were riding out of Beach City.

"Super Watermelon Island"
Garnet, Amethyst, and Pearl form Alexandrite to fight Malachite on Mask Island. However, Alexandrite initially tries to reason with the freed fusion before Malachite decides to fight instead. Seeing as they cannot reason with the fusion, Alexandrite roars and soon clashes with Malachite.

While initially struggling to fight Malachite, to the point where the fusion encases her in a block of ice, the Watermelon Stevens distract the unstable fusion long enough for Alexandrite to gain the upper-hand in their battle and finally defeat her, using Opal's bow to land the finishing blow. Upon catching the falling Jasper and Lapis and reaching the shore, she immediately unfuses out of exhaustion.

"Know Your Fusion"
Sardonyx calls back to Alexandrite, who can breathe a fiery blaze, and asks Smoky Quartz to unleash the elemental chaos she might possess at the target.

"I Am My Mom"
Garnet, Amethyst, and Pearl fuse in an attempt to stop Aquamarine from launching her ship and taking its passengers, Steven and his friends from Beach City, to Homeworld. Alexandrite, who is holding down the ship, lowers it and Steven tells the others to jump into the water below them, which most of them, save for Lars and Steven himself, succeed in doing. However, Aquamarine manages to freeze all her opponents, including Alexandrite, with the help of her wand. When Steven finally decides to turn himself in to Homeworld in his friends' stead, identifying himself as Rose Quartz, Aquamarine releases the humans as well as Alexandrite. This causes the Crystal Gems to unfuse.

"Reunited"
Alexandrite briefly appears to fight Blue Diamond, but is thrown off course and unfuses due to her aura.

Abilities
Presumably, Alexandrite possesses standard Gem abilities and traits.

Alexandrite has incredible amounts of physical strength and stamina; her long legs allow her to cover a lot of ground quickly. She uses her sheer strength and size to lift weighted objects, like a bus. Garnet describes her as "an incredible force on the battlefield", making clear Alexandrite is indeed a formidable warrior, capable of anything as long she keeps a singular goal in mind.

Fusions

 * When fused with Rose Quartz they form Obsidian (Rose fusion).
 * When fused with Steven they form the hybrid fusion Obsidian.

Skillset

 * Weapon Proficiency: As a fusion of multiple Gems, Alexandrite is skilled in wielding a variety of weapons, such as Opal's bow, Sugilite's flail, Sardonyx's war hammer, and the base weapons of the Gems she is composed of.
 * Archery Proficiency
 * Flail Proficiency
 * War Hammer Proficiency
 * Whip Proficiency
 * Spear Proficiency
 * Gauntlet Proficiency

Unique Abilities

 * Anatomy Manipulation: Like Sardonyx, Alexandrite has "doll joints", body segments that have full rotation independent of the rest of her body. She is seen spinning her upper body above her sash while attacking Malachite with Sardonyx's war hammer without impeding her lower body movement.
 * Fire Breathing: Alexandrite can create a plume of fire from her lower mouth.

Trivia

 * Ben Levin stated that, in theory, Alexandrite is taller than Sugilite, due to being composed of four Gems.
 * The "face mask" concept resembles the Crystal Temple, as the Crystal Temple is shown having two faces (the first being the mask on its forehead).
 * When Alexandrite de-fused in "Fusion Cuisine", a still frame of animation shows silhouettes of Ruby and Sapphire where Garnet would have been.
 * The same frame also seems to show the two quickly grabbing each other, likely to re-fuse quickly and keep their existence secret until Steven's birthday.
 * Alexandrite is seen in the mobile video game Attack the Light as a special attack dealing around seven heavy-damage strikes to all opponents on the field, as well as inflicting the attack down and defense down status conditions. She is the hardest attack to use in the game, as she requires nine Star Points and for Garnet, Amethyst, and Pearl to all be at full harmony.
 * A glimpse of her fusion dance is shown during this process.
 * The difficulty of summoning Alexandrite in the game likely reflects the level of difficulty fusing into Alexandrite actually takes, and why they do not form Alexandrite often.
 * Alexandrite has a different outfit the second time she is formed, due to Garnet's regeneration in "Jail Break" and Amethyst's regeneration in "Reformed".
 * The form Alexandrite would have taken in the time between Garnet's regeneration and Amethyst's regeneration is not shown.
 * A hint of her having future vision is that she was able to quickly find the bus Steven and Connie had run away on.
 * Alexandrite's weapon is revealed in the book Guide to the Crystal Gems: It is revealed that her weapon is all of the Gems' weapons.
 * This includes the weapons of their fusions (Opal, Sugilite, and Sardonyx) as well as each Gem's individual weapons.
 * So far she has not been shown to have her own unique weapon.
 * Alexandrite was designed by Rebecca Sugar, Colin Howard, and Danny Hynes.
 * Like Sugilite, despite being an unstable fusion, Alexandrite still has a voice of her own and a humanoid shape.
 * She has four-sided stars on her knees, possibly hinting that she was a fusion of four Gems, Garnet (Ruby & Sapphire), Amethyst, and Pearl.
 * Alexandrite's glasses are a combination of Sardonyx and Sugilite's glasses. The shape resembles Sardonyx's, and the opaqueness resembles Sugilite's.
 * Opal, Sardonyx, or Sugilite can talk through Alexandrite.
 * For example, if Pearl and Amethyst both disagreed with Garnet while fused, they could potentially speak as Opal.
 * This is what allows Garnet to control Amethyst and Pearl's bickering in "Fusion Cuisine".
 * This also means that other yet unknown Crystal Gem fusions can theoretically talk through Alexandrite, those being the fusions of Sapphire and Pearl, Sapphire and Amethyst, Ruby and Pearl (possibly another Rhodonite), Ruby and Amethyst, Sapphire and Opal and finally Ruby and Opal.
 * First shown in "Super Watermelon Island", Alexandrite's fire breath ability was confirmed to be unique to her in "Know Your Fusion".
 * Alexandrite's fire breath may have been symbolism for Obsidian.
 * Alexandrite is the first fusion to have her body plan change after her components regenerated.
 * Her third pair of arms were moved from her chest to her mid torso the second time she was formed, similar to Sardonyx's lower pair of arms.
 * The three lenses on her forehead resemble the dorsal ocelli of many flying insects.
