>>10965140I dunno if you got him, or if you saw what they did with him, but to try and explain, they made two torsos for him.
One that comes on the figure, which is regular, and a version that is rocky. It's basically an entire upper body with different heads and arms and all that.
And they both have the exact same skeletal construction, except one has a ball joint connecting to the waist piece while the other is molded together with the waist piece, which means that its range is severely reduced.
The intention here is that you'll take one body apart and reassemble it onto the "skeleton" that offers more range. But they could've just made the two skeletons identical with very little (basically no) extra work, and it would mean not having to deal with the hassle of taking the figure apart and reassembling it every time you want a different look. You could just pop it off the waist and voila.
