The man is the chieftain of an Aztec Tribe that flourished in Mexico in the 12th to 16th centuries.
He is one of the first characters ever introduced in the entire series and the prefigure to the power of the Stone Mask. Although his opening scene is omitted from the anime adaptation, he appears on a mural in the ending theme, Roundabout.
The chief appears as a man of muscular build with long shoulder-length hair. He is only shown wearing a Stone Mask. He is shirtless with a leopard pelt cape, leopard pelt wristbands, a necklace with fangs, and a loincloth.
As the leader of his tribe, he is viewed by his people as proud and powerful. He is shown to be power-hungry, as he declares that he finally gained eternal life after becoming a vampire. He also seems to be careless of his people, as he drained the life force out of one of his cult members. His tribe is known to be cannibalistic with sacrificial rituals.
During the 12th-16th century, the chieftain sacrifices a maiden on an altar in a ritual. After letting his Stone Mask absorb her blood and becoming a vampire, he proudly announces that he's gained eternal life. Then he asks one of his cult members to become one of his life force; the member agrees, and so the chieftain absorbs the member's blood. The rest of the tribe cheers for the chieftain.
It is unknown what happens afterward, as it is stated that he and his tribe disappeared from history, leaving only their ruins, never to be seen again. Nonetheless, the time of his tribe was the earliest known appearance of the Stone Mask.
