Vucub Caquix

In Mayan mythology, Vucub Caquix was a powerful ruling demon in the underworld, Xibalba and, by Chimalmat, he was the father of the demonic giants Cabrakan and Zipacna. He and his children were arrogant and the divine twins Hunahpu and Ixbalangue[?] killed Vucub Caquix and Zipacna, along with Vucub Caquix's co-regent in the underworld, Hun Came, as revenge for the beheading of their father Hun Hunahpu.
