is a fictional character, possibly modeled on José Gaspar Rodríguez de Francia
, the Paraguayan
dictator who used the same sobriquet, in C.S. Forester
's novels about Horatio Hornblower
, appearing in The Happy Return
. He is an insane and ambitious leader of a rebellion against the Spanish in the Pacific. He is aided and given a captured ship by Hornblower, until Hornblower discovers that the Spanish have switched sides. He is captured by the Spanish and eventually hanged.
He for example demanded a 23-gun salute, as a self-proclaimed superior being.
Some characters in W. E. B. Griffin's The Corps series referred to General Douglas MacArthur as "El Supremo." The main character to do this, Fleming Pickering, is a shipping magnate turned US Marine general from San Francisco. As a seaman himself, he could have been familiar with Forester's works.
