Uno is raised from childhood by a secret organization named the Q Society to be the champion of the Aztec god Quetzalcoatl to battle their enemy, the Aztec god Tezcatlipoca. He is given a magical suit of armor that bestows many abilities, complementing Uno's peak human mental and physical abilities. After his training is completed, he enters the United States and assumes the identity of recently deceased physician Curt Falconer. Aztek later joins the Justice League, but resigns when it is revealed that one of the mysterious benefactors of the Q Society is supervillainLex Luthor. He is later blinded helping the League save the Earth in a battle against the planet-destroying machine Mageddon. Aztek ultimately sacrifices himself to allow Superman the chance to destroy Mageddon/Tezcatlipoca, during the World War III story arc.
Nayeli Constant
A new version of the character appeared in Justice League of America vol. 5 #20; instead of being Uno/Curt Falconer, the new hero is Nayeli Constant. She was a software engineer in Austin, Texas who was startled by the Aztek helmet bursting into her window and telling her about the millennia-long war against the dark god Tezcatlipoca. She decided to accept the role of the new Aztek and modified the armor to suit her purposes; eventually finding her way to Vanity after The Ray left the city to join the Justice League of America. When he returned from a mission, the two encountered one another and briefly argued about who should protect the citizens of Vanity but they teamed up to stop a criminal and decided that the city could use both heroes.
Powers and abilities
Aztek has peak human physical and mental conditioning. He wears an ancient helmet and armor, from which he derives flight, infrared and X-Ray vision, invisibility, intangibility, bodyheat camouflage, entrapment nets, plasma beams and density manipulation, as well as augmenting his peak physical abilities to superhuman levels. The helmet could feed information directly into his brain even after he was blinded in his first confrontation with Mageddon. The four-dimensional power source could self-destruct in a highly explosive manner.
Another version of Aztek, with the same abilities, was seen in Grant Morrison's run on JLA during "The Rock of Ages" storyline in which the JLA traveled to an alternate future overrun by Darkseid. She sacrifices her life to destroy Darkseid's lunar facilities.
In other media
Television
Aztek appeared in Justice League Unlimited, mostly appearing in brief cameos throughout the series. After making a very brief appearance in "Question Authority", he made a more significant appearance in "I Am Legion" where he helped Superman and Shayera Hol investigate where Lex Luthor had gone after escaping prison. Superman asked Aztek to scan the scene to see if he could find out where Luthor went, but had no luck after finishing his scan. King Faraday then appeared behind the trio and introduced himself to Aztek.
