Celestine

Celestine is the fusion between Moonstone, Mint Sapphire, Red Pearl, and Gold Pearl. She's the first quadruple gem fusion in the series to debut. In a moment of desperation, Celestine forms to try and take down Heliodor. Celestine is also what restores Gold Pearl back to her old self after being rejuvenated. She has the unique ability of crystallization which she uses to trap foes in a crystal. She is very animalistic in the sense that she only thinks in actions, what she's currently doing and what she's going to do.
