Bicolano deity of evil and chaos; sealed beneath Mount Malinao after his failed attempt to steal Gugurang's sacred fire. Eponymous progenitor of the broader Filipino aswang folkloric category via his dark-gift transmission to mortal worshippers. Father of the demigoddess sisters Oryol (half-serpent) and Magindara (half-eel) by two different mortal women — the cross-class divine-deity-and-mortal-woman pairings that the Bicolano tradition records.
