Abraham Whistler, one of the best characters invented in a movie universe that didn't originate in the comics. Hopefully Marvel/Disney will keep him around if they ever decide to bring Blade back to the big screen.

Anyway, Whistler was made from a GI Joe: Resolute Duke, with a repainted movie-Thor head, and a vest taken from Indiana Jones' jacket, the leg brace came from the weird shoulder harness thing from Steve Rogers. Gave him a paint job, a couple random guns, and partnered him up with a Blade.
