She was voiced by Jessica Biel.
Vix is very protective and motherly, especially towards Spark, whom she loves deeply. Even when she snapped at him, she instantly regretted it. She's also smart, kind, forgiving, stubborn, caring, friendly, selfless, spunky, strict, strong, and loyal to the point where she’ll literally throw herself in harm’s way to protect Spark. Additionally, she isn’t afraid to get her hands dirty and fight back harder. At the same time, she is compassionate to others and those she trusts.
