Green Lantern #51 (April, 2010)

Another gross guest spot for Black Lantern Martian Manhunter, this time on the final page of a Blackest Night tie-in where Parallax takes back control of Hal Jordan. The Spectre teams-up with a bunch of emotional spectrum ringbearers to deal with that, but absence a soul, he's handwaved away by Nekron. After months of absence, J'Onn J'Onzz's reanimate corpse joins other front end Black Lanterns in standing by their master as the final battle commences. "Parallax Rebirth Part Two" was by Geoff Johns & Doug Mahnke.
