 This approach to Kent's path to becoming Superman was later used in the TV series 
"" and "Smallville", and in the 2005 novel "It's Superman" by Tom De Haven.In the Superman mythos, Byrne wrote Clark Kent as having a more aggressive and extroverted personality than previously depicted, even making him a top high-school football player.Byrne came up with explanations for how Superman's disguise works, such as the public simply does not realize that he has a secret identity since he is unmasked, that Superman would vibrate his face via his super speed in order to blur his image to photographers, and having Kent keep a weight training set around to explain how the human and presumably weaker Kent could have a frame as massive as Superman's.
