which body did Raybot use for this amazing custom?

Ah, so you have one of these in mind? I bet it will be awesome!

I have that Invisible Woman but she's a pretty terrible mold articulation/sculpt wise. He's done a LOT of work on it. I'm holding out for the new Jean Grey/Pheonix body coming next wave.

with as heavily worked as this figure is I don't think base matters a ton between hml fem bodies. It looks like regardless of if you get the IW bod you'll still be in for a TON of work to get that look he got probably no more than any other HML female.just wanted to warn you so you don't buy the base and think its going to be a cake walk from there . Also it appears he wapped the ankles out with someone with rocker ankles not 100% though.

I think your right, now I just need to find one.

The 2-pack one from the looks of it.

Yeah, I wanted to know which invisible woman.

Looks like an Invisible Woman. He usually mentions what he used for the body in his description, might be worth a look.
