Superman has evolved! He has a new power—a powerful solar flare which leaves him -100 energy for a day—and using that power has just shredded his costume, as shown in this discussion of the change Geoff Johns and John Romita.
It all went down in Superman #38, but I missed this until now. I like the new costume with its long sleeves—does it have thumb holes?—and thick soled boots that remind me of my beloved brand Fly London. But beware the trunk factor!
Superman #39 wraps up Johns run on the book. Romita takes over for a couple of issues until Gene Luen Yang comes on board.
