Leyak, in Bali folklore, are humans who practice black magic and are cannibals by nature. In the day, they appear as normal humans, but at night, they are able to detach their heads from the body, dragging along their entrails - heart, liver, lung, etc - flying in search of women who had recently delivered their baby in order to drink their blood. They are led by their mistress, Rangda.
- The Pulsian lettering on its body reads "summoner."
- In the Western Benchland one can see a Leyak worshiping two Rangda standing on a rock next to it.
