Shadow Prove is a 17-year-old Vestal male, the top Darkus brawler within the Vexos during the New Vestroia invasion. He exhibits distinct mannerisms: frequent verbal stumbles, physical twitches, and episodes of uncontrolled laughter. His personality blends a lack of seriousness with persistent annoyance directed at fellow Vexos member Mylene, his frequent mission and battle partner. Professionally, he demonstrates poor piloting skills, resulting in multiple vehicle crashes. His battle record shows significant inconsistency. Early engagements resulted in losses to Baron Leltoy and Marucho Marukura. He later achieved victories against Shun Kazami by deploying his mechanical Bakugan Hades, a replica of Alpha Hydranoid created at his request. Subsequent tag battles alongside Mylene ended in losses against Dan Kuso/Baron and Shun/Marukura. His most consequential victory occurred against Alice Gehabich and Chan Lee on Earth; he destroyed Hades but triumphed using his replacement mechanical Bakugan, MAC Spider. This win lured Dan back to Earth, though it inadvertently caused collateral damage to Dr. Michael's laboratory via his Trap Bakugan Fortress—an action he remained unaware of. Later collaborative efforts with Prince Hydron secured the Aquos Attribute Energy despite battle losses. His character reveals subtle development through loyalty. After Mylene's defeat by Mira Fermin, he voluntarily entered Bakugan Interspace to remain with her, expressing amusement at their predicament and acknowledging their friendship. Earlier, he privately questioned King Zenoheld's genocidal plans for Earth and Vestal, whispering criticism to Mylene that indicated emerging dissent. Shadow and Mylene are the sole Vexos members who never betray Zenoheld. His known Bakugan partners include the destroyed mechanical Hades and MAC Spider, alongside Trap Bakugan Fortress. Minor partners include Darkus Sylvee, while Hammersaur, Anchorsaur, and Atchibee were lost to Baron. Records indicate only three victories across his documented battles. Background details reveal his status as a young Vestal nobleman. His character design shares similarities with later antagonist Anubias, featuring spiky silver hair and Darkus affiliation.
