Chamunda
Chamunda (चामुण्डा), also known as Chamundeshwari, Chamundi or Charchika, is a fearsome form of Chandi, the Hindu Divine Mother Shakti and is one of the seven Matrikas
Chamunda is a fearsome aspect of Shakti, also known as chamundi, chamundeswari and charchika. She is one of the Saptamatruka or seven divine Goddesses. She is also one of the chief Joginis, a group of sixty-four or eighty-one Tantric goddesses. According to 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.
Chamunda Mata is none other than Goddess Kali (Goddess Parvati’s wrathful form/Ugra Roop). She is the wife of Mahakal (Lord Shiva). Goddess Parvati/ Adi Shakti became Kali Mata and slayed the two demons- Chanda and Munda. So Goddess Kali being the slayer of Chanda and Munda got the name Chamunda (slayer of Chanda + Munda).
