Batara Kala
Batara Kala is the god of the underworld in traditional Javanese and Balinese mythology, ruling over it in a cave along with Setesuyara. Batara Kala is also named the creator of light and the earth. He is also the god of time and destruction, who devours unlucky people. He is related to Hindu concept of Kala, or time. In mythology, he causes eclipses by trying to eat the Sun or the Moon.
Origin myth
According to legend, Batara Kala is the son of Batara Guru (the Javanese version of Shiva). Batara Guru has a very beautiful wife named Dewi Uma (Parvati). One day Batara Guru, in a fit of uncontrolled lust, forced himself on Dewi Uma. They had sexual intercourse on top of his vahana Nandi, a divine cow. This behavior ashamed Uma, who cursed both of them so they appeared as fearsome and ugly ogres. This fierce form of Dewi Uma is also known in Hinduism as Durga. From this relationship, Batara Kala was born with the appearance of an ogre.
Another origin story is that he was conceived when a drop of Shiva's semen was swallowed by a fish.
