Asuras (Sanskrit: असुर) are a class of beings or power-seeking clans, related to the more benevolent devas (also known as suras) in Hinduism.
[1] The two major clans of the Asuras are the Daityas and the Danavas.
In the Puranas and other texts of Hindu literature, the deity Krishna is attacked by asuras and rakshasas sent by his uncle Kamsa, as well as others he encounters and slays in his legends.
