Huitzilin
From Tardis Wiki, the free Doctor Who reference
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. After becoming incorporeal, he manifested as "the Blue". (PROSE: The Left-Handed Hummingbird)
