It was revealed that Captain Boomerang's mission for throwing the boomerang was to free Hawk as an avatar of war from the Lords of Chaos because his act of saving Dove would have broken their hold on him to be his own self. However, he failed to catch the boomerang and instead it was caught by Boston Brand, who ended up dying in the process and used his final act to move his white power ring to Alec Holland and bring back the Swamp Thing in order to cleanse the Green of Nekron's influence.
