John D. Rockerduck
John D. Rockerduck, Scrooge's rival
John D. Rockerduck is a character in the Duck universe. He was created in 1961 by Carl Barks for The Walt Disney Company. He is one of Scrooge McDuck's main rivals in Disney comics. His name is a play on that of John D. Rockefeller, the American capitalist and philanthropist. Though a relatively obscure character in the United States, Rockerduck is an example of a character who has become notable outside of the U.S., particularly in stories produced for the Italian market. He made his first animated appearance in 2019, in the second season of the DuckTales reboot.
