She's a white Martian, and I know what those are from having read the the original Blanx stories in Justice League of America #71 and #144 of the original series, and the first arc of the nineties reboot, and some other stories. They're mad, bad, and dangerous to know. I see that through various storylines in the Teen Titans, which I haven't collected for a few years, not really because I didn't like it but because of redirecting comic funds to back issues and suchlike, that she has been revealed as one of the good ones - or maybe the good one.
Anyway, I like the idea of Miss Martian, as it seems like time Martian Manhunter had a kind of girl counterpart. This all falls under the heading of a larger concern, which is that I was thinking about how my Martian Manhunter cred was, for as I revealed in the now classic entry of July 28, I recently bought a shirt with MM, along with several other heroes, on it and started thinking about what a genuinely great character he is. So fortunately there is the great and informative blog, Idol Head of Diabolu, which also looks at Jemm Son of Saturn about whom I unfortunately know very little, though he recently made an intriguing cameo in I believe it was Adventure Comics, in a sequence that I think is meant to help tie together his Saturn with that of Saturn Girl.
I'm not really going anywhere with this, other than that looking at Idol-head and other sources, I feel I might have almost half MM cred, anyway. I have a pretty good number of what are the key MM stories, in one form or another - by which I mean some are reprints of old classics. But I've read those two I mentioned as well as his kind of comeback in DC Comics Presents #27, plus his return to the Justice League and of course the Oreo years in JLI. And didn't he turn into a woman one time in Justice League Task Force? Though I admit I don't have those issues, I was reading a friend's copies. But I guess he has always been there and I think for Justice League members he would probably be the same, the guy who's always there but you don't think about much. Kinda reminds me of me, maybe that's why I like him.
But I really know nothing about his little Silver Age buddy, Zook. Think I might have to go out and get the Showcase reprints soonish.
