Goddess Bhairavi is almost indistinguishable from the terrible Kali. They are much the same in looks, except for the fact that Bhairavi is depicted as the consort of Bhairava. Bhairavi is also referred to as Shubmkari, who is good to good people and terrible to bad ones. Legend has it that, when Bhairavi entered the battle field, her horrible appearance made the demons weak-kneed and cowered under her gaze. Most of the demons would start panicking the moment they saw her.
In Durga Saptashathi, while slaying the demons Shumbha and Nishumbha, Bhairavi is seen as the Mahakali. However, she also slays Chanda and Munda (the Chieftains of asuras) and drinks their blood. Hence, Parvathi gives her the name, Chamundeshwari.
Bhairavi in her other forms, is also identified with Durga. In her violent form, she is sometimes shown sitting on a donkey, her body covered with a tiger skin and skeleton, her mouth dripping with the blood of the asuras. She presents the abhaya mudra (gesture which grants the devotee succour) and vara mudhra (bestowing boons on the devotee). Contrarily, she is also shown holding heavy weapons such as a trident, axe, and thunderbolt.
