Firo Prochainezo

Firo Prochainezo is one of the youngest members of Manhattan's Martillo Camorra family and is a skilled fighter. He was orphaned when he was ten and picked up by the head of the Martillo family after Firo attempts to rob him. Because of this, he considers the Martillo to be his family. He is tasked with monitoring casinos to prevent cheating, and later manages those casinos after becoming an executive member of the family. In 1930, he mistakes the immortality elixir for alcohol and takes it. He later distributes the elixir at a party, becoming immortal himself. That year, he falls in love with Ennis and devours Szilard Quates, saving her and the new immortals. Despite the fact that she does reciprocate his feelings, they live together afterward and eventually marry in 2002. In 1934, he arrested by Victor Talbot for the destruction of public property during the bombing of the skyscraper Mist Wall and is imprisoned on Alcatraz Island. When Maiza Avaro leaves the Martillo in the 1970s, Firo is given the position as the family's bookkeeper until Maiza returns.During this time, Firo wears glasses in an attempt to look smarter. Because he is friends with Luck Gandor and Claire Stanfield, the Martillo and Gandor families are on friendly terms.
