Hel

Hel is a Norse Goddess that is featured in Supernatural: Carved in Flesh.

Appearance
Hel was summoned by Conrad Dippel (the original inspiration for Dr.Frankenstein) and she manifests in the body of Catherine Luss' dead teenage daughter Bekah. She obviously has the appearance of a teenager inspite of being thousands of years old.

Powers and Abilities
Despite only being a Pagan Goddess, Hel is shown to be extremely powerful. She was unfazed even when shot in the head the Colt.

Weaknesses
Incapacitation: Dr. Catherine pretends to join her "daughter" and impales her in the head severing her brain's connections to the rest of the body. The Winchesters then chop the body and bury her in various places so that Hel would be trapped forever in the body and could never be pieced together.
