@addikhabbo: Yeah, How dare they focus on Superman in a Superman comic. smdh!

@saintwildcard:Even if they are from another world or universe Clark (White) has more claim to the shield and title than Luthor does. Who is most likely wearing it only to prove that he could do the job better.

@omni_troll: You couldn't be more wrong. Superman doesn't think he is the law.

@madripoor: Depends, If he is at full power and if he remains near a yellow star then I would say indefinitely, since he is constantly recharging.

@madripoor: Superman is not able to breathe in space. No one can since there is no air to breathe. Superman just doesn't need to breathe so long as he has enough solar energy.
