Luca Brasi was a feared enforcer for the Corleone Family, known as one of the most dangeorus men in the eastern underworld. Fluent in Italian and able to handle himself in any fight, he has a dark reputation among the underworld as a savage killer. Many years before, Brasi impregnated a young Irish prostitute and later murdered her, but did not stop there; on the day of his daughter's birth, he forced the midwife, Filomena under pain of death, to hurl his own daughter into a furnace, an act for which she never forgave herself, describing him as an unholy demon that night. After that night, Brasi killed the young girl and allowed himself to be arrested. He tried to kill himself in his cell with a broken bottle but he didn't die, in the end he was rescued from prison by Vito Corleone, who saw Brasi as a potential asset. The tales of Brasi's prowess soon became legend.At Connie's wedding, Michael Corleone explains to his then girlfriend Kay Adams, the story of how Don Corleone helped his godson Johnny Fontane. Michael explains that his father went to convince bandleader Les Halley to release Johnny from a personal service contract that was holding back Johnny's singing career. After refusing an offer of $20,000 Don Corleone returned the next day with Luca Brasi and within an hour the bandleader signed a release for a second offer of only $10,000. Luca Brasi had held a gun to the bandleader's head while Don Corleone assured him that either his brains or his signature would be on the release contract. Brasi gave a large sum for Connie's bridal purse directly to Vito.Shortly before Vito Corleone is shot, Brasi was summoned by the Don, who intends to draw out rival mobster Virgil Sollozzo and the rest of the Don's enemies by having Luca pretend he had switched allegiances. Luca hung around Bruno Tattaglia's nightclub, eventually going to bed with one of his bargirls and complaining about not making much money, knowing that word would eventually get back to Bruno. When Bruno offers a meeting, Luca drives to The meeting, wearing a bulletproof vest.Sollozzo, after promises of friendship a job, and $50,000 rams a knife into Luca's hand, pinning it to the bar as an assassin garrottes him from behind. A Sicilian message is later sent to the Corleone family: a fish wrapped in Brasi's flak jacket. The meaning is made clear to the Corleones: "Luca Brasi sleeps with the fishes." Brasi's role as personal enforcer/bodyguard to the Don was later filled by Al Neri. Tom Hagen once said to Michael following the completion of Neri's training, "Well, now you've got your Luca."
