I hate those bases, for almost $250 a piece for the set, it looks cheesy and lazy. We got better bases on regular releases then those ie Spiderman, Superman, IM figs, etc. I would have even settled for the metal look of the TDK DX figs. If I saw this beforehand, I would've never ordered at those prices.
guys check out the HT fb page.. looks like that plastic enemy photo shoot reveals that the 89 batman has elbow joint exposed! looks like they might not be using rubber suits after all! yay!
I think the muscle sculpted part could be plastic.
and the under suit is something that allows articulations, but I don't think the joints are visible.
