Your mistake, presumably, is imagining that you can animate a character which is essentially a flat plane, as is the case with your superman.
That is completely unsuitable for animating with the character object, or indeed any method that would deform the mesh, which, in its current state is unable to deform at all because it is made of exclusively ngons. Generally speaking, no model produced from splines in extrudes will be suitable for character animation.
If you want to animate that flat superman you'll need to do it relative to the camera and with PSR transforms only.
