Hi again scott, I have had all my stormies out of the closet today and now I can confirm not any of my looses have such a hard plastic head and torso as the stormie on the kenner moc that I have only the PBP loose that I have. Has the same kind of hard plastic on the head and torso.
The one I have on the moc looks just like he has been painted with white paint just like the PBP looks like. But I know they are not the same because arms and legs are not hard on this one.
I found an auction on ebay, here is a figure that is the same as I have on the moc, but he calls it a PBP, but I don't think it is a PBP.

Is that the other Tri-logo variant you are talking about ?
And if yes, what does a Tri-logo stormie do on a kenner card ?
