Eric Brooks--known as Blade--seeks revenge on Deacon Frost.Deacon Frost, the vampire lord who killed his mother while she was still pregnant with Eric. With all the powers of a vampire with none of their weaknesses, Blade's quest for vengeance leads him throughout Southeast Asia in search of Frost. where, in Vietnam, he discovers a vampire plot that threatens to take down the whole world.
Blade is actually considered a "vampire immune human" due to the rare circumstance of his mother having been bitten by a vampire while she was giving birth.
He was later bitten by a test tube vampire which gave him the strength of a vampire, without their weaknesses.
However, in the films, Blade does still crave blood.
Blade's name is derived from his obvious talent with knives and swords, which he swings around and tosses at monsters with great flourish.
The character originally appeared in Marvel Comics vampire series, staring Dracula, in the 70's. He returned years later to help Spider-Man out with a vampire problem, and has since been absorbed into the greater Marvel Universe, with S.H.I.E.L.D. even designing and supplying many of his weapons.
Blade is part of the Marvel anime series, which also includes the Wolverine and Iron man anime series. No word about whether this series will feature any other popular marvel characters, but I wouldn't be surprised to see at least Nick Fury make an appearance.
Marvel studios is working with Mad House productions and Superhero Anime Partners, so we likely won't have to wait too long for an official subtitled release (unofficial subtitled versions will, of course, hit the Internet within days of each episode, but those are of questionable legality - and sometimes questionable quality).
