Born to a human mother and a vampire father, Eric Brooks was forced to live at an orphanage as his father bit his mother. As Brooks grew up, people discovered he had the strength, speed, and agility of a vampire, but lacked all vampire weaknesses, as he was immune to sunlight and showed no extreme dislike in garlic. When he was fully grown, he became a vampire hunter under the name of Blade and fought for all that is good.

He has had a quarrel with Punisher and Daredevil as well as being an ally of both.
