A psychic vampire called the UnNamed killed off members of a Japanese cult that believed that Martians walked amongst us as evil politicians, bankers, etc. His goal was simply to attract J'onn, though Kindt doesn't give him any real reason to do so. The UnNamed claims that it was merely (and conveniently) to taunt J'onn. He reads J'onn's mind and implies that he's not the last Martian, but instead a creature "built" for destruction. J'onn eventually destroys him, though we're clearly going to have to wait for a few issues to discover what the UnNamed meant about J'onn's origins.
Although this issue wasn't terrible, I'm not a huge fan of back-door pilots, particularly ones that interrupt the story of an ongoing arc. But, if you're a fan of the Manhunter, I'd imagine that you're relieved that DC appears ready to finally decide what they're going to do with him.
