Nahusha (Sanskrit: नहुष, IAST: Nahuṣa) is a king of the Chandravamsha (Lunar dynasty) in Hindu Puranas and Mahabharata.
Hunda assumed the form of a beautiful damsel, and tricked Ashokasundari into coming to his palace, whereupon he attempted to violate her chastity.
Escaping, Ashokasundari cursed Hunda that the son of Ayu would kill him, after which she began to perform severe penance.
[7] Meanwhile, Pururavas, the ancestor of the Chandravamsha dynasty, ruled over the kingdom of Prayaga, with Pratishthana as his capital.
Āyu approached the seer Dattatreya, and after propitiating him, he requested the sage to grant him a son who would be invincible and possess many virtuous qualities which are required for a great king.
Hunda was just waiting for the birth of Ayu's son because he was scared that Ashoksundari's curse would come true.
Nahusha acquired weapons from the gods and killed Hunda in battle and returned to his parents.
[9] In the Dvapara Yuga, when the Pandavas were on their exile after losing the game of dice, Nahusha in his serpent form captures Bhima and decides to eat him.
