Dashavatar
6 - Parashurama, the warrior with the axe. He is son of Jamadagni and Renuka and was granted as boon, an axe after a penance to Shiva. He is the first Brahmin-Kshatriya in Hinduism, or warrior-sage, who had to follow the Dharma of both, a Brahmin as well as a Kshatriya. Once, when king Kartavirya Arjuna and his hunting party halted at the ashrama of Jamadagni, the father of Parashurama, and the sage was able to feed them all with the aid of the divine cow Kamadhenu. The king demanded the cow, but Jamadagni refused. Enraged, the king took it by force and destroyed the ashram. Parashurama then killed the king at his palace and destroyed his army. In revenge, the sons of Kartavirya killed Jamadagni. Parashurama took a vow to kill every Kshatriya on earth twenty-one times over, and filled five lakes with their blood. Ultimately, his grandfather, Rishi Rucheeka, appeared before him and made him halt. He is a chiranjeevi (immortal), and believed to be alive today in penance at Mahendragiri. He also credited for creating coastal belt of Karnataka and Kerala throwing his mighty axe as per Hindu mythology. The place the axe landed in sea got its water displaced and the land which emerged thus came to be known as coast of Karnataka and whole of Kerala
