"Big Atom" from Earth 2 #4 (DC, 2012) by James Robinson, Nicola Scott and Trevor Scott
I'm enjoying Earth 2 on a reboot level, i.e. in finding out how various characters and concepts are going to be re-imagined. I won't always agree with the designs or choices, but at least it's a process of discovery, some of it fairly imaginative. Thematically, the parallel Earth has gone from being about the first generation of heroes to being about the latest, the JSA (not that they're called that yet) following in the footsteps of Batman, Superman and Wonder Woman, heroes that, on their world, have fallen to the forces of darkness.
