You guys are slipping. I run a Martian Manhunter blog, and repeatedly jumped at bait regarding the possibility of a New 52 solo series, with nothing ever coming of it. Finally, for the first time since 2011, fairly conclusive news of at least some plans having been made for such a prospect emerged... in November... and none of you told me. I had to hear about it on "the street." You're supposed to drop by and leave a comment so that I of all people am not the last to know.
Cosmic Book News (who?) broke the pseudo-story a few days before Turkey Day 2013, so that might have contributed to the collective lack of acknowledgment on teh internet, though I'm sure it being an Alien Atlas alert couldn't have helped burn up much bandwidth. Aside from a single image and its artist Brad Walker's involvement to some unexplored degree, there was nothing else to report. I hit up Walker on Twitter to see if I could dig up any more dirt and, yeah, nope...
"No info to give, really. Just one of those things they were thinking about doing that ended up falling through...Best known for his work on Guardians of the Galaxy, along with runs on Green Lantern: New Guardians, and Secret Six, Walker would have been fantastic on J'Onn J'Onzz. I like his stuff a lot, and wish it crossed over with my reading habits more. On the other hand, the Martian Marvel versus anonymous military/SWAT guys? You want to read that? Because me and all the other people on this planet? Don't. If the big fat failure of the 2006 mini-series should have taught us anything, it's that a Manhunter that overemphasizes his otherness while using Superman-class powers against mere humanity does not sell like hotcakes. That's urban vigilante crap. These guys wouldn't make an impressive showing against Nightwing, but they threw in "bulletproof" and "laser vision" to ensure minimal stakes. No word on a writer, and the promo concept was probably cooked up by DC's cancerous editorial, so no great loss beyond Walker. It's a hell of a Goldenesque pin-up, at least. I tried to color it in with my paltry MS Paint SKLZ, but it was so packed with detail I gave up part way through. See the unadulterated, larger-sized art here.
This happens all the time. It was one of several series from that time that didn't pan out."
