Owen Mercer is a hero and sometimes villain who operates as the second Captain Boomerang. His mother is the Flash legacy speedster Meloni Thawne and his father is the criminal Flash enemy Digger Harkness. This gives him limited super-speed in addition to his variety of high-tech boomerangs, allowing him to throw them faster. He has been a member of the Outsiders, the Rogues, the Secret Society of Super-Villains and the Suicide Squad. Owen Mercer was created by Brad Meltzer and Rags Morales, first appearing in Identity Crisis #3. (2004)
