When I remember correctly, there were 4 "normal" and 1 "champion" torso frontpart, but only three legs/backs. But there are enough head and neck parts to magnetize too (armored for the Enlightened and non-armored for the Skyfires). But I only build them as Skyfires without quiver as it was easier.
Yea, the one with the arms spread is the Champion and there are 4 weapon sets included for each typ, 3 normal spears and one spread version, same with the bows.
