In the Golden Age of Comics, Superman made his first appearance in Action Comics #1.
Back then Superman was AWESOME. I mean, I love Superman now, but the Supes of the day... oh wow. He punched crooks, crashed cars, fought the Great Depression, punched some other people and stoped WWII by himself. And he couldn't even fly at this point, just "leap a building in a single bound"
|You crazy badass!!|
He also beat up a guy that was abusing his wife. His badassery knew no end.
Superman is the greatest hero ever. Mainly because he's all that we want to be when we're children: he's honest, brave, and quick to jump into action. And children know best.
