Brom, I believe there were 4 invisible woman minis at that point. 3 you could get in boosters, and ranged from fully visible through transparent versions of the same model. (the transparent one looked cool).
The limited edition Invisible Woman was awarded in much the same way EAs are in WoW, it had no figure and was just a base. It was pretty well received I think. I have one, think it's cute, kinda like the picture box for Invisible Stalker in D&D 2nd Ed. (It's blank, and the 'art' is credited to two of the developers).
I'm sure there'll be a rogue who does a tick of stun on his crits :)
