Viprachitti

Viprachitti is a danava featured in Hindu literature, a son of Kashyapa and Danu. According to the Mahabharata, he becomes the king of the Danavas after his brother Puloman was killed by Indra. Viprachitti marries Siṃhikā, who is the sister of Hiranyakashipu and a daughter of Diti. So, technically they are paternal half siblings sharing the same father (Kashyapa) but different mothers (Diti -Simhika/Holika and Danu - Viprachitti)

He has a son named Svarbhanu. His army is stated to have defeated the devas under the guidance of Svarbhanu.

He and his 13 sons were later killed by Goddess Raktadantika, an incarnation of Kali.

Viprachitti later incarnates as Jarasandha in the Mahabharata.
