Gregorius Reed emerges as a calculating magnate and famed Bakugan collector, wielding strategic brilliance and an obsession with dominating both Aurelus-aligned Bakugan and crystalline Geogan. His former guardians, Aurelus Spartillion and Aurelus Viloch, abandon him after enduring his manipulative tactics. Orchestrating the theft of Vestroia’s Healing Core Cell, he weaponizes the artifact to summon Geogan on Earth, later merging six factional energies into Viloch to birth the unstoppable Ultimate Viloch. This creation backfires when Viloch turns against him mid-battle, triggering his downfall: exposed as the theft’s architect, he loses wealth and prestige, adopting the fractured identity of Ted Janssen.

Consumed by vengeance, he funds the Gate Crushers’ campaign to dismantle Earth-Vestroia links, equipping them with advanced tech to eradicate Bakugan. Defeated repeatedly by rival brawlers and arrested once, he resurfaces wielding a time-displaced Nova Viloch variant, only to be outmaneuvered again. His trajectory spirals from ruthless ambition to embittered retribution, each defeat underscoring his unyielding cunning and access to evolved Bakugan forms—yet every scheme crumbles against coordinated opposition.
