Neptunite is a quiet gem most of the time, she doesn't seems to be problematic but she tends to hide her emotions often, making her look like she is totally emotionless and inexpressive.
She is a really good fighter, but prefers to look like a pacifist, somehow she manages to past unnoticed, but sometimes her bloodthirst wins in battles.
When Neptunite was just a runt, she refused to fight for her people and became practically a "rebel", questioning every authority, including the Diamonds. She vandalized her own barracks in protest, and ended hurting a bunch of gems, leaving explosive traps all around certain bases or monoliths, she didn't care about shattering them, but eventually, a group of Elite soldiers captured her while she was trying to escape from a commander, who almost got shattered by one of her Dark Spheres.
After being captured, Neptunite was going to be poofed for being "defective", but then Red Spinel came back from a mission with her Special Team and current commander, taking Neptunite under her wing and teaching her about what is to be real Warrior.
Neptunite has long hair with blue stripes, and a full body suit like a spacial suit. Also she uses long boots, and some kind of armor in her left arm.
Like most Gems, Neptunite can shape-shift, summon a weapon, fuse, and retreat to her gemstone to regenerate.
- Dark Spheres: she can conjures dark energy spheres, if they are used as a weapon, they can be thrown and implode into the target
- Pocket Dimension
- Void Laser Beam
- Void Barrier
- Neptunite's gem was found floating in outer space, no one knows from where she comes from.
- She seems harmless but... she's not, her abilities with the explosives are incredible.
