Mohini is the only female avatar of the Hindu god Vishnu. She is portrayed as a
femme fatale, an enchantress, who maddens lovers, leading them to their doom. Mohini appears as a form of Vishnu who acquires the
Pot of Amrita
Elixir of immortality
from thieving asuras, and gives it back to the devas, helping them retain their immortality.
Mohini also defeated Bhasmasura, the "Ash-Demon". Bhasmasura invoked the Sun God Shiva by performing severe penances. Shiva who pleased with Bhasmasura, grants him the power to turn anyone into ashes by touching their head. The demon naturally decided to try the power on Shiva himself. Vishnu, witnessing the events unfolding, transformed into Mohini and seduced Bhasmasura. Bhasmasura is so taken by Mohini that he asks her to marry him. Mohini agreed, but only on the condition that Bhasmasura follows her move for move in a dance. In the course of the dance, she places her hand on her head. Bhasmasura mimics the action, and in turn, reduces himself to ashes.
The demon Nontok misuses a divine weapon given to him by Shiva. Mohini enchants Nontok and then attacks him. In his last moments, the demon accuses Mohini of foul play saying that Mohini first seduced him and then attacked him. Mohini decrees that in his next birth, Nontok will be born as the ten-armed demon Ravana and Mohini will be a mortal man called Rama. "He" will then fight him and defeat him.
She also held a physical relationship with Shiva who was enamoured with her female form, siring multiple divine beings, earning the ire of his wife, Parvati.
