Don Lino

Don Lino is the (former) main, but semi, antagonist of ''Shark Tale. ''

Don Lino was the leader of the sharks and he has over three henchmen called Luca, Sykes, Ernie and Bernie. He is also Frankie and Lenny's father. He wants Lenny and Frankie to take over the business and run it together, and is infuriated when Oscar gets in the way. In the end, he redeemed himself, after Oscar confesses that he is not a "Sharkslayer" and that it was an anchor that had killed Frankie. He then strongly urges Don Lino not to prejudge people before he knows them properly and to not make the mistake he made in prejudging his wealth, so Don Lino and Lenny reconcile.

He was voiced by Robert De Niro.
