Justice League, Volume 5: Forever Heroes

Synopsis

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!
