Percival, a Darkus-attribute Bakugan allied with Ace Grit, boasts a fearsome silhouette adorned with dragon-head wrist guards, an armor-plated steel frame, and jagged horns erupting from its head and shoulders. A flowing cape grants brief invisibility, while triple jaws unleash plasma barrages and swirling black tornadoes edged with violet electricity in battle. Their partnership, forged when Mira defeated Ace and bestowed Percival upon him—exposing Bakugan consciousness—fuels their crusade to free enslaved comrades. Percival clashed with Neo Dragonoid to a standstill in their first meeting and joined forces with Shun Kazami’s Ingram at the Vexos Tournament, mastering cooperative tactics to claim triumph. Against Mega Brontes, it executed a cunning ruse—simulating vulnerability before unleashing overwhelming force to dismantle the Alpha City Dimension Controller alongside Resistance allies. A transformative surge emerged when Percival assimilated Exedra’s Darkus essence, evolving into Knight Percival with heightened powers and a deepened bond with Ace. Combat techniques deploy cards like *Tri-Gunner* (G-Power +300), *Darkus Thunder* (stealing 200 Gs from foes while amplifying self by 300), and *Battle Marionette* to compel adversaries onto the field. Standardized at 450 Gs, regional game iterations display variable power scales—Japanese editions oscillate between 440-720 Gs, mirrored in global releases. Once imprisoned by the Vestals, Percival and Ace endured confinement in power-siphoning capsules before escaping with Resistance allies. As Knight Percival, it preserves its fundamental identity while channeling Exedra’s absorbed energies—a progression underscoring ascendance through claimed strength over innate metamorphosis.
