Captain Boomerang is a supervillain and an enemy of the Flash who uses boomerangs for weapons.

Background Information

In the parallel universe, known as Earth-One, George Harkness was a native of Australia, who was raised in poverty, during which time he developed great skill in making boomerangs.

He was secretly the illegitimate son of an American soldier and an Australian woman. He was sent to America by his mother who was desperate to get him away from his stepfather. While in America, he was hired as a performer and boomerang promoter by a toy company which was, unbeknownst to him, owned by his biological father. Audiences ridiculed him, and he eventually turned to using his boomerangs for crime.

He became a recurring enemy of the Flash, typically by devising altered boomerangs which could produce astonishing effects (some would explode, others had razor-sharp edges, etc.), and using them ruthlessly. He became a staple member of the Rogues Gallery, a group of villains dedicated to opposing Flash.
