I don’t see this as a spoiler since this character adorns the cover to Flashpoint Project Superman #3. But, if you wish not to see the picture, forgo the below. :)
So, it was pretty clear after reading Flashpoint Project Superman #1 that DC is building up to a Neil Sinclar (Apollo from Wildstorm) vs. Kal-el (Superman) battle in issue #3 of that mini.
The cover to Project Superman #3 pretty much makes that clear.
However, based on the cover to #3, many were wondering if it would be Kal-el as Superboy vs. Apollo. Nope. Turns outs it is a gaunt adult Kal-el.
So, while there isn’t a full bio in the pic to the right, you do know that Kal-el has been squirreled away from the sun (although that could have been gleaned from how Subject Zero Neil Sinclair was treated in PS #1). So, this pic, in my view, confirms the direction we thought DC would be going. Not heavy spoiler content at all.
Check out this pic and character design in the back of Flashpoint #3 today.
