A demon, son of Madhu.
King Brihadashva of Ayodhya handed the kingdom over to his son Kubalashva and retired to the forest. One day, sage Uttanka came to see him and told him about Dhundhu, who lived hidden in the sand. Brihadashva advised Uttanka to turn to Kubalashva, he would kill the demon.
Kubalashva killed the demon along with his hundred sons, only three survived – Dridhashva, Chandrashva, Kapilashva.
As the destroyer of Dhundhu, Kubalashva is called Dhundhumara.
His son Dridhashva succeeded him to the throne.
