I love the scar and the hair. It is the best part of the design for me. Maybe it gives me some sense of familiarity with the new Jon from the old jon.
I believe the reason it is there is because Jon is going to be more kryptonIan when he returns. So it is a counter balance. I also like the gloves. Wish he kept some more of the old design.Like I said earlier Jon feels like New52 superman.
