Changes

"Shining white Wavern is a wise and kind Bakugan. She is Naga's twin, and they couldn't be more opposite. She holds the positive energy of the Infinity Core inside of her, while Naga has swallowed up the negative Silent Core."

"Wavern is Naga's twin sister, but she's the complete opposite of her evil brother. While Naga tried to steal the power of Vestroia she held the Infinity Core inside her, protecting Vestroia's positive power source. This made her nearly impossible to defeat. The more negative energy aimed at her, the stronger she became."
