Bluto is the arch enemy of Popeye and, like Popeye, wants to do the dirty with Olive Oyl. Despite having a superior strength to Popeye, he is usually beaten because of the super strength Popeye gains through eating spinach. There are some cartoons that show Popeye and Bluto as friends and Navy buddies, with Bluto usually turning on Popeye when an object of interest (usually Olive) is put between them.
