Pratyangira (Sanskrit: प्रत्यङ्गिरा, IAST: Pratyaṅgirā), also called Atharvana Bhadrakali, Narasimhi, and Nikumbala, is a Hindu goddess associated with Shaktism.

[5] According to many Puranas, at the end of the Krita Yuga, a glittering spark appeared from the universe and transformed into a wicked demon named Vipulasura.

Narasimha grew furious and unstoppable due to the evil energies contained in Hiranyakashipu's body that entered into him.

The story ends with Prahlada pacifying Narasimha and he returns to Vaikuntha after assuming his true form as Vishnu.

[9][10] In some images she is shown as dark-complexioned, terrible in aspect, having a lion's face with reddened eyes and riding a lion or wearing black garments, she wears a garland of human skulls; her hair stands on end, and she holds a trident, a serpent in the form of a noose, a hand-drum and a skull in her four hands.

Tantra classifies deities as Shanta (calm), Ugra (wrathful), Prachanda (horrifying), Ghora (terrifying) and Teevara (ferocious).

[14] Worships dedicated to Pratyangira is performed at many places for the welfare of the people and for eliminating the influences of evil forces.

It is further said that any act performed invoking this deity, especially the bad ones like killing and subduing, it is impossible to retract it even when the doer wishes.
