Doctor Death

A sinister presence haunting the pages of Marvel's 1993 The Invaders revival, Doctor Death is one of those darkly named villains who makes the Golden Age feel genuinely dangerous. Debuted by the legendary Roy Thomas and Dave Hoover, this character shares panels with heavy hitters like Captain America and the enigmatic Spider Queen, which tells you plenty about the caliber of threat Doctor Death is meant to represent. With appearances also logged in the Official Handbook of the Marvel Universe: Golden Age Marvel 2004, there's clearly enough lore here to warrant the encyclopedic treatment. Rare in the catalog but rich in atmosphere, Doctor Death is a gem for collectors who love the shadowy corners of Marvel's wartime mythology.
