In Hindu scripture Devi Mahatmya, Chamunda emerged as Chandika Jayasundara from an eyebrow of goddess Kaushiki, a goddess created from "sheath" of Durga and was assigned the task of eliminating the demons Chanda and Munda, generals of demon kings Shumbha-Nishumbha.
She fought a fierce battle with the demons, ultimately killing them.

According to a later episode of the Devi Mahatmya, Durga created Matrikas from herself and with their help slaughtered the demon army of Shumbha-Nisumha.
In this version, Kali is described as a Matrika who sucked all the blood of the demon Raktabija, from whose blood drop rose another demon.
Kali is given the epithet Chamunda in the text.
Thus, the Devi Mahatmya identifies Chamunda with Kali.

In the Varaha Purana, the story of Raktabija is retold, but here each of Matrikas appears from the body of another Matrika.
Chamunda appears from the foot of the lion-headed goddess Narasimhi.
Here, Chamunda is considered a representation of the vice of tale-telling (pasunya).
The Varaha Purana text clearly mentions two separate goddesses Chamunda and Kali, unlike Devi Mahatmya.

According to another legend, Chamunda appeared from the frown of the benign goddess Parvati to kill demons Chanda and Munda.
Here, Chamunda is viewed as a form of Parvati.

The Matsya Purana tells a different story of Chamunda's origins.
She with other matrikas was created by Shiva to help him kill the demon Andhakasura, who has an ability - like Raktabija - to generate from his dripping blood.
Chamunda with the other matrikas drinks the blood of the demon ultimately helping Shiva kill him.
Ratnakara, in his text Haravijaya, also describes this feat of Chamunda, but solely credits Chamunda, not the other matrikas of sipping the blood of Andhaka.
Having drunk the blood, Chamunda's complexion changed to blood-red.
The text further says that Chamunda does a dance of destruction, playing a musical instrument whose shaft is Mount Meru, the spring is the cosmic snake Shesha and gourd is the crescent moon.
She plays the instrument during the deluge that drowns the world.
