They pose just like a regular Minimate. It took me a lot of r&d to get the tolerances just right so that the joints were not too loose. If I would make the ball socket too big, the joints were too loose. If I made the ball socket too small, then I couldn't get arms, legs, etc to pop into them. Then there was always the chance of the knee and elbow joints cracking when putting them together. They still are not perfect, but they can hold their poses just fine. I have quite a lot of extra pieces that I think I might use to make a few dioramas of destroyed Sentinels and then sell them so that people can pose their X-Men with them. Maybe a couple Sentinel heads laying in some rubble, something like that for the little dioramas.
