@@mark-h they cheated by making the legs extra skinny on the toy. These toys were designed with fighter mode in mind so that you could get a nice slim fighter mode. But in lineart the robot's leg a much thicker and muscular. So what you see is a battroid mode on the toy that is not accurate to the lineart in battroid mode. However the anime always gorws and stretches because back then all anime were hand drawn. But in modern times the Vaylkries are CG 3D objects so they don't need to cheat anymore.
