Lobo has a regeneration factor that in some instances allows him to heal from otherwise very severe injury.
Should Superman have the same kind of healing factor? I know he has one - but it has been portrayed inconsistently
Also - while I am sure the topic has been posted and debated before - is he or should he be, immortal - I am not talking (very) long lived - I am talking true immortal like Diana or Vandal Savage - and why?
