The nivatakavachas (Sanskrit: निवातकवच, romanized: Nivātakavaca, lit. 'the impenetrable armoured ones') are a sect of daityas, the children of Kashyapa and Diti, classified under the race of asuras in Hindu mythology. They are best known for their battles against Ravana and Arjuna, the latter of which caused their annihilation.[1]
Thirty million nivatakavachas were born in the daitya clan. Allied with the kalakeyas, they triumphed over the devas in battle. They are described to have been skilled in magic and warfare, wielding powerful weapons to defeat their foes.
