Kaushiki

When Shiva met Parvati he called her Kali, the black one. The anoyed Parvati asked Brahma for light skin.

Brahma granted the wish, Parvati shook off the black one and became Gauri, the light one.

From the shaken off black one Goddess Kaushiki emerged. She destroyed the demons Shumbha and Nishumbha.
