>>5835428Didn't really wanted to bust out a shitty camera. Plus it is easier to tell people who have them than to show it to those that don't.
>>5835433I can work with Snake. Raiden and Kinnikuman are similar designs anyways.
So objective is to get close to a yoga pose, like feet behind the head one. The thighs do rotate at the hip joint, and it can rotate to the point that the back of knee is facing the head of Snake. But, that looks wrong, front of thighs should still face forwards, or at most to the sides. But doing so, if the knees could not rotate, it can only bend to the back, resulting in a cross legged sitting pose. To get the feet closer to the head, and still look like it's a human trying to take that pose, you need to rotate the joints at the knee so the lower leg can reach that high, while maintaining orientations that still looks like a human is doing it. Verses, like a backwards leg creature.
Extreme example, but poses you want to take sometimes requires a high range of motion other figures don't seem to have.
