Dr. James Bradley works at Mercy Hospital treating victims of crime day in and day out. He decides to become a crime fighter and disguises himself with a surgical mask and trenchcoat. He is not afraid to use the tools of his trade on criminals and often uses a needle full of truth serum that sends a person into a temporary coma and the subconscious mind forces him to tell the truth to any question to get to the bottom of a mystery.
His enemies included the Surgeon and X2 . He worked together with his fiancee Mary Strong, a nurse who had no idea about his crime fighting secret.
Dr. Nemesis turned up in marvel's 1990's Invaders mini-serie, as the leader of the villainous Battle-Axis, using the name Dr. Death , and returned again, back to being the ( more or less ) heroic Dr. Nemesis in Uncanny X-men in 2008.
