Nino Santangelo is an influential Cuban heroin dealer. After Lincoln Clay kills Sal Marcano's second capo, Marcano is in need of money to bribe the governor in order to open his casino, so he agrees to let Santangelo sell drugs in New Bordeaux in exchange for his financial support. Santangelo's only request is that he be allowed to kill Lincoln Clay.
When Santangelo attempts to ambush Lincoln in the French Ward, his men are killed and he's fatally wounded. As he lies on the ground dying, he utters one last racial insult at Lincoln, who states "My name is Lincoln Clay" before plunging his knife into Santangelo's throat, killing him.
