JulianPerez, the last we saw of the Ten-Eyed Man was in "Crisis on Infinite Earths #12" -- he was trapped in the collapsed building debris that also partially covered the unconscious Huntress. Kole's dome apparently covered him too, so his actual fate is unknown (we never really SAW the Shadow Demons kill Kole, Huntress and Robin in that dome).
Morrison brought back Prince Ra-Man (another Crisis victim) at least in a sense, in his recent SEVEN SOLDIERS miniseries, stating that (presumably) he ascended to be a cosmic being, King Ra-Man.
Hey, "Rock of Ages" had some darn cool moments.. I can live with a cliched story if it's written well.
Some of it was pretty neat, though the hardlight hologram evil-JLA battle was pretty boring, and he got almost no use out of the Injustice Gang concept; they were barely used, almost window dressing to prop up the grandeur of the story instead of being real antagonists.
I did love the giant future earth space monsters Aquaman summoned, and the fact they had some wonderful use of Argent, one of the unjustly forgotten Teen Titans, who was shown operating at her full awesome capacity. This has created the potential for a future story where we see our Argent become the Argent seen in that possible future. I’m surprised (considering how everything Morrison did received a sequel somewhere) that nobody has ever followed up the potential that this story offered with that character, showing signs in the present of Argent’s future development.
