Eric Brooks, a half-vampire, gained all the vampire strenghts, but none of their weaknesses. He has trained to fight since childhood, becoming so skilled with daggers and swords that his vampire prey took to calling him Blade after the weapons he used to destroy them.
While Blade has not registered as a Superhuman, S.H.I.E.L.D. has decided not to bother him as he has proven not to be a threat to civilians and has single-handedly kept the United States Vampire population in check. S.H.I.E.L.D. also has a plan to pit Blade and fellow vampire hunter Union Jack (Universe 2009) against each other in case they need to dispose of either of them.
