Biography

George "Digger" Harkness

Born into an impoverished family, he took up throwing boomerangs as a special talent. Later, he tried to make a living by selling toy boomerangs at a toy store. The customers made fun of him and mocked his toys, so he turned to a life of crime.

Owen Mercer

The son of the previous Captain Boomerang, Owen was abandoned by Digger, and raised in a foster home. Owen later learned that he is half brother of the current Kid Flash, Bart Allen, from his father, shortly before his death. After a brief stint with the superhero team, the Outsiders, Owen returned to the side of evil during the Blackest Night when he feed the hearts of the living to his Black Lantern father, and was killed by his fellow Rogues for breaking their rules.

Powers and Abilities

Captain Boomerang has no real powers, but he is a mechanical genius, capable of making special boomerangs that explode on contact. He has also been known to create boomerangs with especially sharp edges.

Owen, being Bart's half brother, had limited super speed.
