Aztek was a superhero in the DC Universe. He was created by Grant Morrison and Mark Millar. Aztek's series was critically acclaimed, but only lasted ten issues. He also appeared in several issues of JLA also written by Morrison.

A young man named Uno was raised by a secret society (the Q Society) to be the champion of the Aztec god Quetzalcoatl to battle their enemy, the Aztec god Tezcatlipoca. He was at the peak of human abilities both physically and mentally. He was armed with a magical suit of armor that had several powers including flight, invisibility, super strength etc. His base of operations was Vanity City, a strange town that had bizarre architecture and the highest suicide rate in the DC Universe.

Aztek later became a member of the Justice League but felt he had to resign when it was revealed that one of the mysterious benefactors of the Q society was supervillain Lex Luthor. He was later blinded helping the league save the Earth in a battle against the planet-destroying machine Maggedon, which, apparently, was the 'Tezcatlipoca' that the cult was referring to all along. Finally he sacrificed himself to allow Superman the chance to destroy Mageddon/Tezcatlipoca.
