Hun-Apu

In Maya mythology, Hun-Apu was a son of Hun Hunahpu and a virgin. His twin was Ixbalanque; the tow were the Maya Hero Twins. Their father Hun Hunahpu was beheaded by two underworld demons, Vucub Caquix and Hun Came.

Hun-Apu and Ixbalanque decided to kill their father's murderers, as well as Zipacna, son of Vucub Caquix. They made a crab decoy and told Zipacna where he could find a giant crab to eat. When Zipacna went to the spot, they threw a mountain on him, killing him.

Hun-Apu became a sun god and his brother, Ixbalanque, became a moon goddess, switching genders.
