Franco, a tan-skinned explosives specialist with long black hair, brown eyes, and a beard, apprenticed under his uncle, a master bomb-maker, before dedicating his life to the craft. After his uncle’s death, he spiraled into isolation and alcoholism, abandoning his work until meeting Franca—a freelance terrorist adopting the alias Caterina. Her vision of reshaping Italy by attacking its judicial system reignited his purpose. Franco resumed bomb-making, becoming her protector and technical advisor while she liaised with terrorist factions, notably those supporting the Padania Republic, supplying them with meticulously crafted explosives.

Clad casually in jeans and light jackets, Franco evolved from a reclusive, near-silent figure to someone who occasionally engaged associates like Pinocchio with gruff camaraderie at Franca’s vineyard. His devices, infamous for their complexity, integrated unorthodox components like cell phones repurposed as detonators. The partnership ended violently when Franco, Franca, and Pinocchio were killed in a clash, leaving their associate Cristiano paralyzed and bent on vengeance against the Social Welfare Agency.
