The idea is that after Superman is mortally wounded by Doomsday (who killed Superman in a comic book run many years ago) he dons the suit so that he can heal.
As you can see from the clip below, we are talking about a very different iteration of the suit from any previous incarnations, even if it is a “special” suit for a particular predicament of Kal-El’s. Enjoy the photos and video below and then let us have your comments. Do you wish this vision of Superman had seen the light of day? Does a suit adorned with glowing fibre-optic cable fit your idea of what his costume should look like?
