- ―Frankie's last words.[src]
Frankie disapproved of Lenny's compassionate nature and although he did love him, he had no qualms about hitting him, despite his mother telling him and Lenny that they shouldn't hit each other. Frankie was later killed when an anchor dropped on him while he was chasing Oscar in an attempt to eat him; his last words to Lenny was, "Moron." Frankie hit him and insulted him by calling him a moron just before he dies. when his brother told him the reason why he was cold was because they, as sharks, are coldblooded. During Frankie's state funeral, he was wrapped after the Egyptian-styled embalming. All the sharks, including Lino, mourned and they buried Frankie by opening the fragile box and put him into the burial site for him who died. Later on, the wrapped Frankie floated to the surface.
In Shark Tale
Vicious, bloodthirsty, an aggressive killer shark, and a true great white, Frankie was the complete opposite of Lenny in personality: Unlike his brother, Frankie won't hesitate to eat any fish if he was hungry and he often got exasperated by Lenny being reluctant to kill anything. He did love and care for his brother, but he sometimes hit him and never hesitated to do so. Frankie was also mean and cruel to Lenny sometimes; at one point in the film, when Frankie jokes to Lino that Lenny being born was an accident, Lenny responds to this by laughing sarcastically and telling Frankie he is a "comic genius". Due to his brother9's gentle nature and because of it, Frankie was willing to run the reef alone once his Leno retired as he reluctant to get him involved in his father's criminal empire as he knew Frankie shouldn't have in him to be ruthless, even defending his brother from being put through a test to make a real shark.
Frankie will sometimes box with his father, which he liked to do.
Frankie had close relationships with many of his relatives, including his parents (his and Lenny's mother was never seen in the movie, due to her being away for quite a while) just as they were completely devastated by his passing. Despite their quarreling, it has been shown many times that Frankie truly loved his brother Lenny, in his own way.
Frankie was a muscular great white shark. He has a notch in his dorsal fin and a scar on his left cheek.
- At one point in the film, he is seen at the restaurant eating oyster shells, but real-life sharks eat meat.
