Vali the Mathcless Warrior

There was an asura named Dundubhi, 

1. who once challenged Varuna for a duel. 
2. Varuna sent him to Himavan and the asura wreaked havoc with the peaks. 
3. Himavan approached him, told him that he was a peaceful being, and if he wanted a fight, he should seek Vali. 

Dundubhi reached Kishkinda and challenged Vali. Vali killed him and threw the body away. Matanga was meanwhile meditating on Rishyamuka mountain nearby. Blood drops from Dundubhis nostril fell on Matanga, who used his divine sight to realise who was responsible. He cursed that Vali would die if he entered Rishyamukachala.

Dundubhi had a son named Mayavi, who swore to avenge his father. He lost his life in fight with Vali
