Of course by "antibodies" I'm totally not thinking of that late-80s Marvel New Universe character Anti-Body, a doctor who generated featureless telepathically-linked humanoid duplicates that could envelop him and take him flying until whoops the mysterious go left him perma-trapped inside one and he could only look 'normal' again by a friend carefully putting makeup all over his ectoplasmic 'skin', why would I be thinking of that in great detail?
@zebratron2084 It was one of the first (and, turns out, last) non-kiddie comics I followed regularly. Really liked a lot of what it put together, although Anti-Body, the Mutator, and ... uh ... the woman who'd been in Codename Spitfire were particular deep interests.
