Vayuphak, also known as Asuravayuphak (fig.), is a creature from the Ramakien, half-bird, half-asura (fig.), who ruled the Kingdom of Wichian, located at the slopes of the Universe. He waged war with Phra Ram (fig.) and Phra Lak (fig.), whom he captured with the intention to eat them.

However, Sukrihp (fig.) and Hanuman (fig.) fought over them and liberated Phra Ram and Phra Lak. Eventually, Vayuphak was beheaded by Rama's monkeys, led by Ongkhot (fig.) and Nilaphat (fig.), a scene portrayed in this mural from the Royal Palace in Phnom Penh (fig.).
