Strange Twins

Golden Age Origin
Doug and Rod Strange are identical twins who were separated at birth. Doug became a highly respected inspector with Scotland Yard. Rod became a dangerous criminal mastermind. Initially, they did not know of each other's existence, and were indirectly linked by Rod's crimes. When they finally met, Doug became determined to track down his mysterious look alike. So began a war between the brothers, in which each impersonated the other, or one captured the other and delivered them to their own enemies. Eventually, Doug managed to convince Rod to go straight, and the two of them battled crime together.
