Wavern (Earth-101001)

Wavern (Japanese version Wyvern (ワイバーン, Waibān)) is a wyvern-like Bakugan with no Attribute (Being a member of The White Ones). She is Joey's Guardian vessel and Drago's main love interest, as well as the twin sister of Naga, a major enemy of the brawlers.

Description
She held the Blue Core inside of her, protecting it from Naga, who held the Red Core. She is kind, even though she is an outcast to the other Bakugan.

She is also Joe Brown's Guardian Vessel. She used the power of the Blue Core to cure Joey and get him out of the hospital. He later was able to use only her to defeat Masquerade in a battle. She and Drago had been going out on dates before the Blue Core incident. It started when Drago slipped between the attributed world and he met Naga and Wavern. He kept visiting her ever since. She still has affection towards him. Her pet name for him is "Dragoruny." She and Drago also share a great connection with the Perfect Core, since they were both together.
