Spectra Phantom, born Keith Fermin, is a Vestal shaped by familial ties and a relentless quest for power. The son of Clay Fermin and older brother of Mira Fermin, he once nurtured a protective bond with his sister, training her in Bakugan strategies and embracing a casual, pink-haired persona. This warmth faded as he reinvented himself as Spectra Phantom—masked commander of the Vexos in *New Vestroia*, clad in a crimson leather coat, spiked blond hair, and a voice-altering mask revealing one piercing eye. His Guardian Bakugan, Pyrus Helios MK2 (later Darkus Infinity Helios in *Mechtanium Surge*), mirrored his ambition to ascend as the “ultimate Bakugan,” driving him to deploy forbidden ability cards, hostages, and betrayals while scorning morality. He dismissed revered figures like Apollonir as relics and manipulated allies such as Gus Grav, whose loyalty endured despite Spectra’s opportunism. A turning point arrived when Mira defeated Gus in a duel, compelling Spectra to unmask and confront his identity as Keith, exposing fractured but lingering family ties. Prioritizing power over reconciliation, he pursued Drago’s Perfect Core energy and engineered cybernetic upgrades for Helios—Cyborg Helios, Helios MK2—clashing nine times with Dan Kuso before a three-episode climax shattered his ambitions, sparking self-reflection. Post-defeat, he shed the Spectra mantle, rejoined the Resistance, and aided in dismantling Zenoheld’s Alternative Weapon System, though his battlefield tactics remained unyielding. In *Mechtanium Surge*, Keith resurfaced as a Darkus brawler, donning a black mask with dual eye slits and a frayed-edge ensemble. Teaming with Darkus Infinity Helios, he targeted Mag Mel’s Chaos Army, critiquing Dan’s leadership while offering pivotal aid in crises. His bond with Mira evolved into a guarded brotherly rapport, though their interactions grew sparse. Themes echo Masquerade: masked identities, blond transformations, and rivalry with Dan. His combat blended *Dragon Ball Z*-inspired martial arts with multi-attribute Battle Gear strategies. Post-redemption traces of Spectra lingered—sporadic mask use, Vexos-era gauntlets in battle. Notable details include a three-year age gap with Mira, past experiments with forbidden cards hinting at Bakugan casualties, and the Japanese epithet “Glacial Blaze.” His arc concluded with a temporary self-sacrifice in Interspace, marking a transition from ambition to altruism.
