Dr. Byron Orpheus is a necromancer and Dr. Venture's friend and tenant on The Venture Bros.  Dr. Orpheus may not have the ability to raise the dead, but he's certainly a nercromancer in every other sense of the word having a direct portal to the necropolis in his daughter's closet.

Speaking of which, Dr. Orpheus has a cute daughter, Trianna, that Dean Venture crushes on major.  Orpheus is probably the most competent, powerful good guy (besides Brock Samson!), but mostly uses his power to help him cook breakfast.
