Justice League Volume 5. Forever Heroes

As the Crime Syndicate hunts down the few heroes left foolish enough to challenge them--including Batman's protege, Dick Grayson. But Owlman has other plans for Nightwing. . . and Owlman's teammate: the most deadly being on the planet: Ultraman! Also, Cyborg is one of the lone Justice League members left to fight against the villains that have taken over. How can he possibly find a way to defeat them? Who can he turn to? Two words: Metal Men!
