Don Lino is the (former) main, but semi, antagonist 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.

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.
