Huitzilin

 was an Aztec warrior. He was exposed to radiation from a crashed Exxilon spaceship, causing his nascent psychic abilities to expand drastically. This enabled him to feed on the deaths of others, but the more he does so, the more he needs to continue living. He was the inspiration for the legend of the god Huitzilopochtli.
