616 Moon Knight origin and the use of magic
I actually used to collect Moon Knight back in the 80's, both series, and so after much debate, got off my *** and found issue one from the first series (I think the first series) from Nov 1980.
Moon Knight started out being similar more to DC's Vigilant then Batman, although I'm sure they both have their roots in that character. I make that comparison becasue while there is hinting of a mystical origin (hell, Vigilant's origin has him being trained by spirits) that element is actually mostly ignored. Unlike someone commented earlier, Marc Spector was not an archeologist, but was a mercenary fighting in a war in Sudan. He'd been hired by a guy with the dubious african name of Bushman, who had a skull tattooed on his face, with steel teeth - which he didn't think might lead to the moral dilemma it, of course, lead to.
Basically, Spector refused to fight the war, especially when a blond woman who screams and cringes alot was kidnapped. Marc is captured by Bushman's people and is, of course, left for dead in the desert (why these bad guys never actually make sure people are dead is beyond me). He wakes and stumbles around the desert for a day or so before collapsing, where he is found by the people he had originally been fighting the war against, and just to prove how aulteristic they really are, bring him inside a tomb, where they leave him. He wakes up and decides that the reason for his revival was because of the statue of Khonshu he was laying in front of. Marc takes the cape and hood from the statue and rushes off to free the woman and avenge himself on the Bushman.
And in the process a strip joint is refered to as a "jiggle joint". I only include that because it is possible the single funniest thing I've read in a comic in years.
Now, I recall that in the second series, Moon Knight aquired nunchucks, but originally he used moon shaped throwing knives (hmm, familiar sounding) and didn't really have to much of a problem of killing people. This also changed in the second series where he became more nonlethal.
And that's how Moon Knight 616 came to be...with as little cynicism as I could muster. Hope that's helpful...and I hope it's nothing like what Bendis has written because if it is I'll be disappointed. I don't even mind the mystical angle being played up more than it appears to have been done in the original run, just so it isn't quite so silly sounding.
