A sect of Daityas.

दैत्यस् were the off-springs of कश्यपप्रजापति by दिति . Two sons called हिरण्याक्ष and हिरण्यकशिपु and a daughter called सिंहिका were born to the प्रजापति of दिति . सिंहिका was married by विप्रचित्ति and to them were born राहु and others who became famous as the सैंहिकेयस् . हिरण्यकशिपु had four famous sons called अनुह्लाद , ह्लाद , प्रह्लाद (the great devotee of विष्णु ) and संह्लाद . (Some texts refer to them as अनुह्राद , ह्राद , प्रह्राद and संह्राद ). ह्लाद 's son was called ह्राद , संह्लाद 's sons were called आयुष्मान् , शिबि and बाष्कल , and प्रह्लाद 's son was called विरोचन . महाबलि was विरोचन 's son and बाण was the eldest of the hundred sons of महाबलि .

Four crores of asuras called निवातकवचस् were born in the family of प्रह्लाद . The army of the Asuras, which routed the Devas many a time, was formed by the निवातकवचस् and कालकेयस् . (Agni Purāṇa, Chapter 19) .

Fight against रावण

After securing boons from ब्रह्मा निवातकवचस् lived in the city of मणिमती and they were a terror to the world. रावण longed once to defeat them and so besieged their city with his army. The two sides fought fiercely for hundreds of years. At last ब्रह्मा intervened and conciliated them. From that day onwards the निवातकवचस् became friends of रावण . (Uttara Rāmāyaṇa) .

Annihilation

The निवातकवचस् in company with the कालकेयस् attacked देवलोक . Indra, who could not withstand the attack, sent his charioteer मातलि to अर्जुन and brought him down. Most of the निवातकवचस् and कालकेयस् were killed in the fight by अर्जुन . (See under Kālakeya)
