Blade

Blade, a.k.a. the Daywalker, first appeared in Marvel comics Tomb of Dracula no. 10. His origins are very unusual. His mother was in labor, and the doctor called in to assist was the white-haired vampire Deacon Frost. Frost bit and fed from Blade's mother as she struggled to give birth to her son, and as a result of his unusual circumstance Blade is immune to vampire bites. He is also faster and stronger than ordinary mortals, and has some of the blood thirst of a vampire. He is known to vampires as the DayWalker because he has many of their strengths but he can walk in the sun unharmed. He has dedicated his life to hunting down Deacon Frost and other vampires.
