Don Lino is the main antagonist of Shark Tale. He is the father of Lenny and Frankie, and a crime leader. After he heard that the Sharkslayer "killed" Frankie, he wanted to tear him fin from fin, until he realized that Oscar lied to him, and became friendly, along with his henchmen. He wasn't very proud of his younger son being a vegetarian, but at the end, he'd love him no matter what he eats or what he dresses up like. He is voiced by the legendary actor Robert De Niro.
