Recently discovered Zetman, by Masakazu Katsura, and have to say it was worth the buy. The author is a long time standing fan of Batman, so for any Batman fans out there, I say it's worth a look. Great art, the story-line is a tad bit stretched at time, but you can learn to get over that. I can't really give anything away about the story, without ruining the suspense that is set-up at the beginning of the story. The basic premise is the creation of artificial humans, and sort of like mass-Frankensteins. For those who read "Invincible," by Image Comics, this would seem very familiar. These being live in hiding from humans, and I think I'll stop right there.
