Is it just me or is the character that is front and center Jon Kent because all I've seen is people identify the two tiny characters in the background of this low quality image but absolutely nothing about what should be more obvious than Jakeen Thunder and Thunderbolt?
Allegedly, Waid's Batman/Superman and his upcoming Batman vs. Robin deal with time travel or something like that, so I can see this as a potential solution to the age up problem but I don't want to reach.
