Victoria Montesi is a hero in the fictional Marvel universe, who was created in 1992 and has often appeared in stories involving the Darkhold.
Victoria Montesi is a human/demon hybrid, whose father out of desperation used the Darkhold to get his wife pregnant. She is one of Chthon's spawn but stands in opposition against the Old One. She was a founding a member of the Darkhold Redeemers, a team of mostly normal humans who fight the Old Ones and those that would use the Darkhold.
Recently she was a member of the Midnight Sons, a team of supernatural superheroes. Chthon once used her to attempt to return to Earth via her womb. Due to her being a Chthon spawn, her aging has drastically slowed and for the last 3-4 decades has continued to look as if she was in her 30s.
