He was the son of Vikukshi. He is regarded as a very powerful King. Once when the Gods and Demons fought, Indra asked Puranjaya’s help. Puranjaya said that Indra needs to be his vehicle and then he would fight the demons. Indra took the form of an Ox. Puranjaya rode Him and defeated the demons. He gave all the riches, kingdoms that he obtained to Indra. Since Puranjaya rode on the hump of the Ox, he is also called as Kakutsth. He is also called as Indravah since Indra was his Vahana.
