Elsa Bloodstone

Elsa Bloodstone is a superheroine from the Marvel Comics created by Dan Abnett, Andy Lanning, and Michael Lopez, first appearing in Bloodstone #1 (dated December 2001).

History
Elsa is the daughter of Ulysses Bloodstone, an infamous monster hunter in the Marvel Universe, whose super strength and immortality were derived from the mystical Bloodgem embedded in his chest. Elsa's relationship with her father has been subject to continuity drift; while it was originally established that she never knew him prior to his death, later materials explicitly mention that he raised her to be a hunter like himself. Her nationality is also disputed; like Emma Frost, she's ostensibly from Boston, but more recent appearances suggest an English persona.

Nonetheless, Elsa's own path in life isn't dissimilar to her father's, becoming a prominent monster hunter in her adult years. At some point after Ulysses' death, Elsa came into the possession of a Bloodgem choker, effectively granting her the same powers as his —- but since her Bloodgem is worn externally, she's more susceptible to danger than he ever was.
