Priest

Well...he's not really undead, but I suppose that was the closest category I could think of. His name is Arlen Kane, a.k.a. "Priest." He is an original character of mine, created for a story I currently have in progress. He is half vampire, half human, a crossbreed species known in my story as "vampeil." He is a sort of vampire hunter, working as a "paranormal investigation agent" under a larger government influence in the year 3500. There's more to him than that, but I wouldn't want to drone on in my explanation.
