In the Hindu text the Devi Mahatmyam, Nisumbha, also spelled as Nishumbha was one of the two Asuras that confronted, and were ultimately slain by, Devi.
The story of Sumbha and Nisumbha begins in the fifth chapter of the Devi Mahatmyam. The Devi relates how two brothers of Asura stock sought to conquer the Three Worlds by subjecting themselves to severe penance and purification rituals so that no man or demon could destroy them. Sumbha and Nisumbha traveled to Pushkara, a sacred place, and remained there in prayer for ten thousand years. God Brahma saw the brothers' penitence, and was pleased, granting them the boon they requested.
It was at this time that Chanda and Munda, two lesser Asuras in the service of Sumbha, encountered the Devi, and were overwhelmed by her beauty. They carried reports of this goddess to Sumbha, who sought to possess the Devi and her beauty. Sumbha sent the Vanara Sugriva to court the Devi, but she rejected his advances. It was then decided by the demonic brothers that if the Devi would not come willingly, they would have to abduct her. The demon Dhoomralocana and his retinue of sixty-thousand Asuras were sent to kidnap the Devi, but she and her lion-steed managed to slay the entire army. Next, Chanda and Munda were deployed, but the Devi destroyed them as well.
After these encounters, Sumbha and Nisumbha had no choice but to meet the Devi in direct combat. Although Brahma's boon had granted the brother's protection against men and demons, no such protection existed against goddesses. Nisumbha was the first to fall, after assaulting the Devi's lion. After Nisumbha's death, a powerful demon emerged from his corpse, but Devi managed to dispatch this monster as well, by decapitating it. Upon seeing the death of his brother, Sumbha went after the Devi in a rage, but was ultimately cleaved in two by the Goddess' trident. With Sumbha and Nisumbha gone, the Three Worlds returned to their ordinary state of being, rid of a great evil.
