The son of Vincent Vanetti. He has a bright and positive personality, and he values his family above all else. He believes that The Vanetti family, runs Lawless and that the Galassia Family is trying to force its way in. Nero believes in a family's pride, refusing to back down to the Orcos or the Galassias, no matter what, if they demand something that will demean his family.

Seven years prior to the story, he shot and killed Testa Lagusa, Avilio's father, alongside Vincent Vanetti and Vanno Clemente. He later takes over the don of the Vanetti from his father Vincent.
