a ring flying in to revive him as a Black Lantern. The Black Lantern Owen and his father are then encased in ice by Cold. His father manages to escape and join in the mass battle against the heroes where he is brought back to life and full health. Powers and abilities Captain Boomerang carries a number of boomerangs in his satchel. He is an expert at throwing the weapons and as well as ordinary boomerangs he has a number with special properties, including bladed, explosive, incendiary, and electrified boomerangs. Upon his resurrection, Digger finds he has the ability to create boomerangs out of energy that explode on contact. However, this new ability is lost when he completes the task given by the White Lantern Entity. The original Captain Boomerang then began to train his son Owen Mercer before he died. He has exhibited creativity in his boomerangs by creating "razorangs" and an acid-spewing boomerang. Owen has also exhibited "speed bursts", short bursts of limited super speed over short distances, most notably when throwing boomerangs. These were even possible during the time period that Bart Allen fully contained the Speed Force, usually displayed as his ability to throw boomerangs at high velocities, rather than running. However, during Chang Tzu's experiments, he claimed he believed Mercer could access the Speed Force, and Mercer denied having super speed at all anymore, but Chang Tzu was able to activate Owen's speed involuntarily, causing him great pain. The exact source of this power remains unrevealed. Regardless, as of Justice Society of America #8, the Speed Force appears to have returned and is accessible to all former speedsters once more.
