Opal is the fusion form of Pearl and Amethyst. She is voiced by Aimee Mann. 


Amethyst and Pearl are extremely powerful when they're willing to work together in the form of Opal. Amethyst's ability to live in the moment, plus Pearl's obsessive single-mindedness result in a stable fusion. Opal achieves a peace in that balance that Amethyst and Pearl rarely experience on their own.
