Barong is a character in the mythology of Bali. He is the king of the spirits, leader of the hosts of good, and enemy of Rangda in the mythological traditions of Bali. Banas Pati Rajah is the fourth "brother" or spirit child that accompanies a child throughout life. Banas Pati Rajah is the spirit which animates Barong. A protector spirit, he is often represented by a lion, and traditional performances of his struggles against Rangda are popular parts of Balinese culture. The Barong is often portraited with two monkeys.

The animal/ mythical creature would dance along the street to the calonarang dance. A priest would throw Holy Water at it. It is known as the Demon Queen and Mother of All Spirit Guarders.

The lion barong is one of five traditional Barong. In Bali each region of the island has its own protective spirit for its forests and lands. Each Barong for each region is modeled after a different animal. There is a boar, a tiger, a dragon (or serpent) and the traditional lion. The lion is the popular one as it comes from the Gianyar region where Ubud (the home of tourist viewed ritual) is located. Within the calonarang, the dance drama in which the Barong appears, the barong responds to Rangda's use of magic to control and kill her to restore balance.
