A while ago I bought the last issue of Dan Slott's run because it purporeted to contain an explanation of the mis-characterization and the continuity problems which did and do plague today's MU. It did, but I didn't realize that part of my enjoyment of the explanation was predicated on having read Fantastic Four #160-163. As I mentioned in another thread last week, my FF collection is merely nigh complete, and those issues are four I'm missing. They're readily available on the backissue market, but priced out of my range. Besides, the next Essential FF with start with those four issues.
However, the alternate Earth featured in those stories (Earth-A, for "alternate") originally debuted in FF #118, which I recently re-read for the first time in many years. After that I thought I'd give She-Hulk #21 another read. The inhabitants of Earth-A (here come the SPOILERS) are entirely super-powerless, except for Reed Richards who transformed into the (or rather "a") Thing. What I remembered from that issue is that non-powered vacationers from Earth-A were travelling to "Earth-B" (i.e., Earth-616, the MU proper), and gaining the powers (if any) of their super-powered counterparts, thus ecplaining myriad discrepacies in characterization.
What I didn't rememeber (and am asking someone to confirm) is that the She-Hulk from Dan Slott's entire run (?) was apparently Jenifer Walter's Earth-A counterpart. Is that right?
Also, while I'm at it, in which series/issue did Tony stark inject She-Hulk with transformation-inhibiting nanites?
