Fango is a prominent secondary antagonist in the mafia-themed drama, recognized for his volatile and unpredictable nature. He is a member of the Orco family, though his ultimate ambition is to seize power for himself and establish his own criminal organization. Unlike many of the more calculating figures in the series, Fango acts on impulse, often escalating situations with extreme violence rather than planning his moves carefully. He has little empathy for others and displays a clear enjoyment of sadomasochism, suggesting a deep-seated psychological instability and a cruel streak.

In terms of appearance, Fango is designed to stand out. He is a physically fit man, often depicted with chin-length blonde hair accented by a distinctive red streak. His typical attire leans towards a cowboy aesthetic, including a brown bomber jacket, an open shirt, denim pants with leather chaps, and cowboy boots. This unusual look for a Prohibition-era gangster sets him apart from the more traditionally suited members of other families. His voice and demeanor project an ostentatious and challenging energy, making him an immediately menacing presence on screen.

Fango's primary motivation is power and survival within the brutal world of organized crime. He is quick to feel disrespected and uses even minor slights as justification for extreme retaliation. His role in the story is that of a chaotic catalyst, a wild card whose actions frequently upset the fragile balance of power between the Vanetti and Orco families. He first comes into conflict with Nero Vanetti over stolen alcohol, an encounter that nearly costs several characters their lives. Later, after surviving an assassination attempt ordered by the Vanettis, Fango uses the death of his subordinate, Serpente, as a pretext to demand open war against his rivals, defying his own Don in the process.

Key relationships define his arc. His dynamic with Avilio Bruno, the protagonist, is particularly tense and opportunistic. Avilio initially tries to kill Fango but later seeks his help to rescue a captured ally. Fango, ever the pragmatist, rejects emotional pleas but is persuaded by a tactical argument, agreeing to help Avilio and Nero in exchange for them capturing his own boss, Don Orco. This deal highlights his lack of loyalty, as he betrays the Orco family without hesitation to take control for himself. He is frequently accompanied by his much more sensible subordinate, Gatto, who often appears uncomfortable with Fango's erratic antics but follows orders nonetheless.

Throughout the series, Fango undergoes a significant, if violent, development from a soldier in the Orco family to the self-proclaimed Don. After Avilio and Nero deliver the drugged Don Orco to him, Fango executes a brutal takeover. He kills the old Don and, in a horrific display of power meant to cement his authority, serves his predecessor to his new crew as a meal, declaring his new faction the Fango family. In terms of abilities, Fango is a proficient marksman and combatant, capable of shooting bottles out of the air during a gunfight. However, his most notable ability is his sheer unpredictability. His tendency to act before thinking makes him a dangerous foe, as he is willing to take risks and use extreme brutality that more traditional mobsters would avoid. Despite his rise to power, his volatile nature proves to be a weakness, leading to his eventual demise at the hands of Corteo, who kills him after Fango tries to steal a valuable alcohol recipe.
