Fan Casting Blade (MCU)

Eric Brooks was born in a whorehouse in the Soho neighborhood of London, England in 1929. His mother Tara Brooks was a prostitute at Madame Vanity's Brothel. When Tara experienced severe labor complications, a doctor that was summoned who was in actuality vampire Deacon Frost who feasted during Eric's birth which killed Tara. However, this inadvertently passed along certain vampire enzymes to the infant. This resulted in Eric's quasi-vampiric abilities, including a greatly prolonged lifespan and the ability to sense supernatural creatures, as well as an immunity to complete vampirism. Tara's fellow prostitutes drove off Frost before the infant could be killed as well.
