In the Classic style, a shell serves as his ear ornament. He often carries shield and lightning-axe, the axe being personified by a closely related deity, god K, called Bolon Dzacab in Yucatec. The Classic Chaac sometimes shows features of the Central Mexican (Teotihuacan) precursor of Tlaloc."

"Dedicated to the Tlaloque, this veintena involved the sacrifice of many children on sacred mountaintops. The children were beautifully adorned, dressed in the style of Tlaloc and the Tlaloque. On litters strewn with flowers and feathers; surrounded by dancers, they were transported to a shrine and their hearts would be pulled out by priests. If, on the way to the shrine, these children cried, their tears were viewed as signs of imminent and abundant rains. Every Atlcahualo festival, seven children were sacrificed in and around Lake Texcoco in the Aztec capital. They were either slaves or the second-born children of nobles.
The festival of Tozoztontli (24 March – 12 April) similarly involved child sacrifice. During this festival, offerings were made in caves. The flayed skins of sacrificial victims that had been worn by priests for the last twenty days were taken off and placed in these dark, magical caverns."
