I disagree again Chris. Blade could be a great character, as multifaceted as fellow vamp hunters Buffy, Angel, Anita Blake, or Damali Richards if he is approached right. (I haven't read any Blade comics. I'm basing these ideas off of the Blade movies).
1) For one, you have to get inside the character, make him more vulnerable, give him more of a personality. The cold persona adopted by Wesley Snipes worked well on film. However, it left the character static. He didn't change. There would be blips of emotion-Whistler's 'death' in 1, staking his mother in 1,watching Nyssa die in 2, and Whistler's death in 3, but we never really got to see how it changed him.
He went right back to hunting. Beyond Blade 1, we never really got to see Blade struggle with his hunger, his inner demons. Basically, he's grappling with an addiction, and there's great stuff for character development with that, and its something many of us can relate to. A lot of people are addicted to various things-drugs, food, sex, shopping, TV, Internet (LOL), etc. Plus, Blade has some self-hate issues that could be mined.
So, who is Blade? What does he want? Where did he learn his martial arts skills? Does he listen to music? Does he read? Does he watch TV or movies? Does he ever take time off? Is he still a virgin?
And if all the vamps died tomorrow, what would he do with his life? While reading the script for Blade 2, there was a love scene between him and Nyssa, and though fan boys hate romance/relationships, I think it would've added something to the Blade character, made him more human.
Another thing, where is Blade's human father? Has Blade ever tried to look for him? If so, what happened? Perhaps his father has also become a vamp hunter after Deacon Frost attacked Vanessa, Blade's mother? But what if Blade doesn't jibe with his father's methods or something?
And what about Blade's otherness, his sense of alienation? He's neither human or vampire, and though he identifies more with humans, how does he feel knowing that humans would be terrified of him? How does he deal with his uniqueness? The loneliness?
The movies made mistakes by not playing up the sexual tension he had with both Karen Jenson and Nyssa. I don't want Blade going out like a punk, getting soft. But I wouldn't mind him developing, or fighting his feelings for a person. It would give him something more personal to fight for.
2) I think his rogue's gallery is limited only by imagination. Just looking at stuff at Wikipedia, there are some good villians there. Dracula, Deacon Frost, Madame Lavelle (sp), Night Terror, Varnae. And I would love to see a return of the Reapers in some form.
With a comic you can go beyond vampires to explore all manner of supernatural lore like the shows Supernatural, Angel, X-Files, and Buffy. But even keeping the villians solely vampires, you could do a lot.
The vampire houses touched on in the first Blade could each be explored in depth, also why did Damaskinos look so different than other vamps? There could be other ancient vamps like him out there. Also, the familiars have never been explored. I think that's a large pool of enemies that could also be developed. Blade not only has to fight against individuals, but organizations and systems.
3) Developing a small team of Nightstalkers, Midnight Sons, or whatever, would also give Blade more people to interact with and play off of. The Blade-Whistler duo worked fine for the movies. (Didn't care for the inclusion of the Nightstalkers in Trinity, because they took away from Blade rather than add something to him.)
But in a comic, a small cast of characters could lead to more story possiblities. For one, every character has to have an origin, a reason for hunting vamps. That's going to lead to stories, family members, and potential villians right there.
My prescriptions for a Blade comic: Keep it simple, add some complexity to the character, and make it a mature book that is as R-rated as the movies. Like I said in a previous post, reimagine the character to fit the Goyer characterization. As a nod to the original Blade, take the villians and some of the better storylines and adapt them.
I wish I could get a hold of a Blade comic, perhaps an Ultimate Blade.
