From wikipedia: After the theatrical Popeye cartoon series went out of production in 1957, Bluto's name was changed to Brutus because it was (wrongly) believed that Paramount Pictures, distributors of the Fleischer Studios (later Famous Studios) cartoons, owned the rights to the name "Bluto." (King Features owned the name all along as Bluto had been originally created for the comic strip. However, due to poor research, they failed to realize this, and renamed him Brutus to avoid copyright issues.). "Brutus" appears in the 1960-1962 Popeye television cartoons (with his physical appearance changed, making him obese rather than muscular), but he is again "Bluto" (and back to his original muscular physique) in the 1978 Hanna-Barbera Popeye series and the 1980 Popeye movie, as well as Hanna-Barbera's 1987 Popeye and Son series. Brutus was also the name Nintendo used for their arcade game based on the property. Another subtle difference between the characters of Brutus and Bluto is that while Bluto was often portrayed as a fellow sailor who also sought to win the heart of Olive Oyl, Brutus was portrayed as a generic villain, or bank robber, who showed no romantic interest in Olive. Instead, he usually took her hostage, leaving Popeye to rescue her. Prior to the name change to Brutus, the bearded strongman was known as "The Big Guy Who Hates Popeye," "Junior," "Mean Man," and "Sonny Boy" in the comic strip and comic books. The name "Brutus" was first used on Popeye-related products in 1960 and in print in 1962. It is generally accepted that Bluto and Brutus are one and the same. However, Ocean Comics published a one-shot "Popeye" comic book where Bluto and Brutus were twin brothers. Bobby London, who drew the "Popeye" daily strip for six years, wrote and illustrated the "Return of Bluto" story where the 1932 version of Bluto returns and discovers a number of fat, bearded bullies have taken his place, calling themselves "Brutus" (each one being a different version of Popeye's rival). On December 28, 2008 and April 5, 2009, the Popeye comic strip called Bluto the twin brother of Brutus. In Latin America, the character was always called "Brutus". If King Features owned the rights to Bluto, and let Paramount Pictures use Popeye to begin with, why couldn't they just use Bluto?
