Blade

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