When all is said and done, Clark Kent, Bruce Wayne, and Peter Parker will always be Superman, Batman, and Spider-Man. Despite some plot twists and ill-timed deaths, those characters will always be the alter egos of the iconic superheroes we've known for over 50 years.

Someone growing up in the '60s probably has a different sense of what the Bat Signal looks like, than a Millennial will. And in 2013, the powers behind Man of Steel, made headlines after tweaking Superman's iconic "S."
