Considering what a huge impact the first Blade film had on the comic book movie (essentially reviving it after Batman & Robin killed it with camp), its kind of amazing how much the movie has been swept under the rug. Even within the world of the Blade films, we never get another mention of NBushe Wrights Karen Jenson, a hematologist who gets dragged into this seedy underworld of monsters after shes bitten by a vampire and rescued by Blade. A stereotypical damsel character would have probably freaked out in this situation, or been reduced to arm-candy there only for expository purposes and so the villain has someone to threaten. Instead, Karen accepts that vampires exist and devotes herself to finding out a way to fix her situation, while also having the guts to walk right into the vampires den alongside Blade with only a fraction of his arsenal and not a single bit of his training or powers. Karen serves a role almost equal to Whistler, perhaps a bit more. Shes the one who devises a way to not only help Blade deal with the growing threat of his vampire site, but also devises a method that proves to be the undoing of Deacon Frost. The first film seemed to set up Karen to take over Whistlers old role, but unfortunately we never got a single mention of her in the sequels.
