Don Lino is the main antagonist turned supporting character of Shark Tale. He is the mafia boss of the reef, the Great White Sharks, and Sykes (before, anyway), Lenny and Frankie's middle-aged father, and his wife's husband. He was bad at first but after Oscar telling the truth Don Lino turned good.
Lino reappeared in Club Oscar, in which he danced with the sharks.
He is voiced by Robert De Niro in the film and short and by Jim Meskimen in the video game.
