Parashurama

King Kaartaveerya-arjuna and his army visited Jamadagni, who fed his guest and the whole army with his divine cow; the king demanded the cow and Jamadagni refused because he needed the cow for his religious ceremonies. King Kaartaveerya-arjuna sent his soldiers to take he cow and Parashurama killed the entire army and the king with his axe. In return, the princes beheaded Jamadagni. In revenge, Parasurama killed the entire clan of Kaartaveerya-arjuna, thus conquering the entire earth, which he gave to Kasyapa.

According to one legend, the story goes on that Parashurama was struck by remorse at his wanton killings, and offered penance on a mountain top. The sea god Varuna responded, and offered him land equal to the distance he could throw his axe. Parasurama threw his axe from Gokarnam[?] and it fell at Kanyakumari[?]. As promised the sea gave way to land, thus giving rise to Kerala.

Parashurama also went to visit Shiva once but the way was blocked by Ganesha. Parashurama threw the axe at him and Ganesha, knowing it had been given to him by Shiva, allowed it cut off one of his tusks[?].
