Bluto done it.
Bluto vs. Brutus
After the theatrical Popeye cartoon series ceased production in 1957, Bluto’s name was changed to Brutus because it was incorrectly believed that Paramount Pictures, distributors of the Fleischer Studios (later Famous Studios) cartoons, owned the rights to the name “Bluto”.
King Features actually owned the name, as Bluto had been originally created for the comic strip. Due to a lack of thorough research, they failed to realize this and reinvented him as Brutus to avoid supposed copyright problems.[3]
“Brutus” (often pronounced “Brutusk” by Popeye) appears in the 1960–1962 Popeye the Sailor television cartoons, with his physical appearance changed, making him morbidly obese rather than muscular. He normally sported a blue shirt and brown pants, and didn’t appear to wear any socks.
