Justice League Vol. 5 (The New 52)

In these tales from JUSTICE LEAGUE #24-29, the Crime Syndicate hunts down the few heroes foolish enough to challenge them - including Dick Grayson! But Owlman has other plans for Nightwing...and Ultraman, too! Also, Cyborg is one of the last 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!
