Vulcan Haestus commands Freeze Force as its Colonel, leading a unit dedicated to apprehending the Burnish. His imposing presence belies a compact frame, smaller than allies like Lucia and Lio, amplified by armor that exaggerates his silhouette. Dark-skinned and bald, his orange eyes pierce with intensity. He wears a segmented bodysuit of green and white, accented by a green shoulder pad and striped plating encasing his right arm.

Hardened and prone to volatile outbursts, Vulcan relishes his role with fervor, yet his zeal twists into cruelty and arrogance. He dominates subordinates through intimidation and abuses his authority, masking insecurity with overbearing theatrics. The Burnish he hunts are dehumanized in his rhetoric, dismissed as mere fuel. His allegiance to Kray hinges on self-preservation, not loyalty, positioning him as a pivotal antagonist whose actions escalate tensions between Freeze Force’s ruthless operations and the societal fractures they exploit.
