Myth has it that Kali sprang from the brown of the Goddess Durga in the
middle of a full-scale battle wherein Durga was fighting the demons,
Mahisasura, Sumbha and Nishumba at the behest of the gods who had begged
her to save them. Kali appeared black, naked (or draped in tiger skin),
and "emaciated, wide-mouthed, lolling-tongued, with deep sunken red
eyes."8 She severed the heads of Canda and Munda, servants of the
demons. Then she took on the demon, Raktabija:

     From the blood shed from his wounds sprang thousands of fresh combatants,
     representing the destructive masculine principle. To annihilate this 
     archtypical power, Kali again and again drank the rakta-bija (the seed 
     blood). This symbolic devouring represents the "taking possession of" or 
     rendering harmless of an overpowering destructive element, a 
     phallic power.9

The Morrígan was the war goddess of the pagan Irish. She is a horrific
goddess personifying war the way the ancient Irish saw it: loud, chaotic,
glorious, bloody and heroic. She is savage and deceitful, bloodthirsty,
revelling in the gore of battle. She comes as a carrion crow or a hag,
portending or causing violent death. Yet she is no mere demoness. She
fights for her race, the Túatha dé Danann, against the invading
Fomoire. She has a strange relationship with Ireland's great warrior
Cú Chulainn: by fighting him, she forces him to rise to his greatest
glory. Under other names — Nemain, Macha, Fé, Badb, the Washer at the
Ford — she shows aspects of motherhood, sorcery, prophecy and teaching.
