To be added when Mr. Napcakes isn't super lazy!
She doesn't have a definite personality. The fusion herself is extremely unstable, so she has 2 personalities; Kyanite's and Rosaline's. Kyanite is a cold-blooded sadistic gem while Rosaline is a gem that can be accepting and loving once you befriend her. The only thing that's probably the same about them is that they're both determined to get what they want.
Like all gems, she has the ability to shapeshift, summon a weapon, and fuse. Her weapon is a long-bladed gladius, which can create black-hole like structures by slashing it freely in the air. She has Rosaline's matter manipulation. She's very unstable, so it's very unlikely that she'll use these powers effectively.
Rosaline and Kyanite both dislike them.
Rosaline cares about the 11-year old boy dearly, while Kyanite thinks less of him. Since they're a fusion, their relationship is pretty confusing.
- She's the first fusion introduced in the series that isn't affiliated with the Dawn Dusk Gems.
- This doesn't count Abbelite, who was a fusion in the crossover, because she belonged to a different user.
- She's the first fusion with 2 voice actresses.
