Abilities / Powers

Firo’s standout abilities arise from his consumption of the immortality elixir, enabling him to survive injuries that would be fatal to ordinary humans. His fighting skills are honed through years working as an enforcer, making him highly formidable in hand-to-hand combat and with weapons. Notably, Firo’s immortality allows him to recover quickly from wounds, but it does not grant invulnerability; he still feels pain and can be incapacitated temporarily. As the story progresses, his combat prowess advances, adapting to increasingly dire situations.

Major Story Arcs & Growth

Firo’s character development is most pronounced during the central events of the series set in 1930, particularly surrounding the immortality elixir’s chaos and its repercussions on the characters’ lives. A pivotal moment is when he inadvertently becomes immortal after mistaking the elixir for alcohol and subsequently distributes it at a party. His interactions with Szilard Quates culminate in Firo devouring Szilard to save Ennis, showcasing his protective nature. The evolution of his relationship with Ennis, from initial indifference to mutual love, marks critical growth in Firo’s emotional understanding.

In the 1970s, after Maiza Avaro leaves the Martillo family, Firo takes on the role of bookkeeper, demonstrating his ability to adapt to changing family dynamics and responsibilities.
