I would be Blade because he has all the powers of vampires, with none of their weaknesses. Combined with his martial arts skills and his gadgets, he has the strength, know-how and skill to clean up the night, plus the style to look good while doing it.

Done in Daz Studio, using Michael 3, standard textures. Clothing combines SecondSkins and the Stormguards vest, retextured. Rendered in 3Delight engine. Initially used Garibaldi Hair for hair/mustache/goatee, but ended up painting over them in Photoshop. Used layers and several filters to get the final look.

It took about six hours altogether.
