In traditional Hindu mythology and ancient epic literature such as the Mahabharata, the Kalakeyas are a fierce clan of powerful Asuras (demons or titans) who are frequently described as the progeny of Sage Kashyapa and Danu. Mythological texts recount them as formidable adversaries to the Devas (gods), often possessing immense dark magic and military might, leading to legendary celestial wars before they were ultimately vanquished by divine heroes like Arjuna.
