El Dorado was created solely for the Super Friends cartoons and did not appear in the main DC Universe until 2017. He first appeared as minor character in the Super Friends animated shorts, which aired in 1981 season and later in Super Friends: The Legendary Super Powers Show as a full-time member. El Dorado spoke English with an accent, sporadically substituting common Spanish words or phrases, such as adding words like "rapido" and replacing nearly every instance of "yes" with "si".
In El Dorado's debut episode "Alien Mummy" it is revealed that he is of Mexican descent. The narrator sets the scene by describing the location as 'ancient Aztec ruins in the Mexican wilderness'. One of El Dorado's lines is "these are the mysterious ruins of my people".
LEGO Batman Movie
The mysterious El Dorado is one of the most enigmatic members of the Justice League. He can teleport himself and other objects by wrapping them in his cape, and create illusions of solid light to trick and trap his foes. He might also have super strength, laser eye beams, or possibly telepathy. No one knows exactly how he got his mighty powers, and El Dorado isn’t saying. Maybe he likes keeping it a secret…or maybe it’s just that nobody has asked him yet.
Bat-Fact: I found El Dorado once. The legendary long-lost city of gold, not the guy.
