Antenora the Hungry.
She's a demon.

She eats only hearts of unfaithful men, and has a small cult (of women; most of whom come from abused backgrounds) following her.

She can cut her hair and weave it into armor that is indestructible when worn by mortals. Strands of her hair can be also woven into regular cloth, and it gives "normal" clothing the properties of high-quality bulletproof vest.
