Don't mess with this Celtic war goddess: you will die. It is known. Often a conflation of three goddesses, the Morrigan is a shapeshifting warrior who mostly appears as a wolf, a raven, or, less dramatically, as an old washerwoman. Why should Superman be afraid of some old lady? Because if she happens to be washing his suit, he's dead Kryptonian meat. The Morrigan has a special relationship with death, and she only appears to those who are about to succumb to it. It doesn't matter where you're from — County Dublin, County Sligo, or County Krypton. You won't survive a glimpse of the Morrigan.
