Tlaloc - “He who makes things sprout.”

The mysterious rain god Tlaloc was depicted wearing a mask with large round eyes and long fangs. He bears a striking resemblance to Chak, the Mayan rain god. Tlaloc was considered to be both a benevolent deity, providing life-giving rain for crops, and an inexorable, destructive being, sending storms and drought.
He was associated with any meteorological phenomena associated with rain, such as storms, floods, lightning, ice and snow. He also ruled over the otherworldly paradise of Talocan, which contained victims of floods, storms, and diseases such as leprosy.

Tlaloc's main sanctuary was second only to the Huitzilopochtli sanctuary atop the Great Temple of Tenochtitlan (Templo Mayor).
