Justice League Unlimited #15

The fall of Mr. Terrific! Neron's plan is finally revealed — and the fallout could spell the end of heroism on Earth. As souped-up villains continue to bring the devastated planet to its knees, the Terrific Ten is whittled down to a handful of survivors who can barely hold the fires of hell at bay.

The Justice League — including Superman, Batman, Wonder Woman, The Flash, Aquaman, Cyborg, and Green Lantern — faces its darkest test yet.
