Trisiras

Trishiras (), also referred to as Vishvarupa, was the three-headed son of the craftsman god Tvashta. He was killed by Indra, the king of the devas. To avenge his death, Tvashta later created the demon Vritra.

==In Hindu Scriptures== ===Vedic=== In the Rigveda, Vishvarupa is the son of the god Tvashta and the guardian of cows. He is an enemy of Indra, the king of the gods, who comes into conflict with him. Indra is victorious in the conflict and Aptya (an ally of Indra) kills Vishvarupa, and Vishvarupa is then beheaded by Indra. Another verse states that Indra stole Vishvarupa's cattle and released them. The Brihaddevata narrates that Vishvarupa is the son of Tvashta and his asura wife, and the twin of Saranyu. He is sent by the demons to become the priest of the devas, desiring to destroy them. Indra suspected his intentions and beheaded him. His three heads turn into three different birds. Furious by the demise of his son, Tvashtr creates a demon called Vritra to avenge his death.
