Here she is, the Rock Mom you've all been waiting for (or, two of you at least.)
She wasn't based on Alphys at all LOL whaaaaaaat
Name: Carneilian / "Carrie"
Alignment: Homeworld, Yellow Diamond
Owner: Yellow Diamond
Personal Motivations: Carnelian feels that fusion is disgusting, yet powerful. In order to be channeled effectively, a fusion should be able to function like a single gem, like Vein. She aims to create a forced fusion so perfect that other gems think that it is a single entity, yet has the power of something like Maachite.
Gender: Female (she/her)
Gem Location: Right hand
Rank: Techie. She works with fusion experiments.
Appearance: A red and orange gem with a poofy head of hair, a bandana around her neck, a puffy, tucked-in bi-colored shirt with a Diamond insignia on the left breast, a dark pair of tights and boots with yellow heels and toes.
Weapon: She doesn't have a weapon and relies on technology.
High understanding of how gems work and can locate weak points on any gem
Deep understanding of fusions
Synchronizing Style/Fusion Dance: She doesn't fuse, as of right now.
Personality: A nervous little thing, Carnelian is a nerd who would prefer to spend time in the lab than out with friends. She's very sensitive and cries easily, never speaks up to give an opinion, and doesn't have too many friends. She stutters a bit when she does talk and is constantly self-conscious of her defects.
Brief History/Backstory: After emerging from the Beta indergarten during the war, Carnelian realised that she didn't have much of a chance. She was a terrible soldier and had to rely on hand-to-hand combat due to a lack of a weapon, so she was supposed to be crushed and added to the cluster after the war ended. However, Carnelian was able to recognise several flaws in the force-fusion experement system, and was spared to become part of the team that oversaw them. Because of her belief in a perfect permafusion, she was taken aside by Yellow Diamond and commissioned to create super-soldieresque to serve on an elite force for the Diamonds. Her creations were immediately poofed, bubbled and sent to the Diamonds, but she always felt a shred of responsibility for each one upon perfecting them.
Her glasses aren't an accessory, they're functional.
She's suuuuuper gay and if anyone were to flirt with her even the slightest bit she would be in love with them forever. Maybe even enough to fuse with that someone.
