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 did so, the more he needed to continue living.
Huitzilin was the inspiration for the legend of the god Huitzilopochtli, also known as the Blue Tezcatlipoca. After becoming incorporeal, he manifested as "the Blue". During this event, he mind-controlled Mark David Chapman into murdering John Lennon, known best as a former member of the Beatles in 1980. (PROSE: The Left-Handed Hummingbird)
