From Wikipedia: "Tlaloc (Classical Nahuatl: Tlaloc ['t?a?lo?k]) was an important deity in Aztec religion, a god of rain, fertility, and water. He was a beneficent god who gave life and sustenance, but he was also feared for his ability to send hail, thunder and lightning, and for being the lord of the powerful element of water. In Aztec iconography he is normally depicted with goggle eyes and fangs. He was associated with caves, springs and mountains. He is known for having demanded child sacrifices." (
