Kazarina, a Haos Brawler and high-ranking member of the Twelve Orders, serves as Emperor Barodius’ second-in-command. Commanding the Bakugan Biological Research Center, she pioneers unethical experiments on living Bakugan and humans to amplify Gundalian military power, prioritizing the unlocking of Bakugan evolution. Her development of Exokor—using stolen DNA from Drago to evolve Dharak into Phantom Dharak—cements her status as Barodius’ most trusted ally.

Driven by ruthless pragmatism and self-interest, she sacrifices subordinates like Lena, Jesse, and Zenet to evade consequences for failures. She openly scorns fellow Orders members, rivaling Gill for Barodius’ favor and betraying Nurzak after a temporary alliance during a coup. A central antagonist in the Gundalian-Neathian war, she is fueled by a vendetta against Fabia Sheen, having murdered Fabia’s fiancé Jin and inflicted torturous experiments on Aranaut before his escape.

In the conflict, she wields hypnosis to manipulate Earth-based brawlers—a tactic criticized by Ren Krawler for impairing combat effectiveness. She masterminds assaults on Neathia’s security shields and orchestrates Jake Vallory’s abduction, attempting to brainwash him into dismantling the Third Shield. Her schemes climax in a final battle against Fabia and Nurzak on Gundalia. Stripped of her weapon by Nurzak, she meets her end when Gill executes her with her own blade, avenging her manipulations.

Her death shatters the hypnosis on allies and cripples Gundalian forces. Lumagrowl, her partner Bakugan, persists briefly in combat before reconciling with Aranaut. In *Bakugan Dimensions*, she appears aboard a Gundalian ship, upholding her role as a strategic leader.
