Contrary to popular belief, but costumed crime fighters existed before Superman was first published. They weren't called superheroes, as that term was not coined yet, but they were instead called a few names. Crime fighters, mystery men, masked adventurers, the list goes on. Some even had what could be considered superpowers, though they were either magical or explained that they had trained to achieve them.
However Superman is the one that broke the mold and established the superhero. The clearly superhuman feats, the bright colorful costume, it all came from Superman.
However this leads me to the Pulp heroes, as they are called now. The original costumed crime fighters such as The Shadow
The Green Hornet
And Lone Ranger and Zorro
Today the spirit of these characters live on. They live on in one of the more popular characters in comics............... Batman
Batman shares the same spirit with the pulp heroes of old. He wears dark colors like the Shadow, The Spider, and Zorro. Also like Zorro has a hideout under his home and like both The Shadow and Zorro passes himself off as an unassuming wealthy man. Like The Green Hornet and Lone Ranger he has an equally iconic crime fighting partner. Batman also uses gadgets, in a similar manner to Green Hornet who utilizes a gas gun. He also has an iconic mode of transportation very much like Lone Ranger, Zorro, and Green Hornet as well. Also his colorful rogues gallery is in fact almost entirely lifted from many Pulp heroes who also had unusual and sometimes downright vile enemies. In fact the very first Batman story published was a total replica of a Shadow story!
Batman also works in a more grounded reality, without the need for the supernatural or fantastic, something that many Pulp heroes are set in. Sure, they have SOME elements of the fantastical, but for Batman these small amounts work as well. So is Batman the last true Pulp hero or not?
