Captain Maggie Sawyer is a dedicated and no-nonsense member of the Metropolis Science Police; a special branch of the Metropolis police force that handles super powered menaces when Superman is unavailable.
Born in Star City, Maggie Sawyer was once married to another police officer named James Buchanan Sawyer, however, she divorced him after determining that she was a lesbian.
Later transferred to Metropolis, Maggie served the Metropolis Police Department as a captain on the department's Special Crimes Unit.
