Adolf Hitler, Jr.

Adolf Hitler Jr. was the son of Adolf Hitler, conceived shortly before his father's suicide and his mother smuggled out of Berlin in secret, her death faked while he was raised to rever his father's memory as the new leader of the Fourth Reich, preparing rituals using what he believed to be a scrying glass while he gathered his forces in an Antarctic naval base. His existence was uncovered by the Sixth Doctor, Claire Aldwych, and Brigadier Lethbridge-Stewart, Hitler Jr. being killed when he attempted to force the Doctor to take him back in time to meet his father only for his father to shoot him in the head in the belief that he was only a madman.
