Across the thousands of stories that Batman has been a part of, only a small percentage have really made a definitive mark on the character, changing the way readers see him. These stories, which are still too many to count, shape the overall mythology of Batman, adding to the character and the universe around him in ways no one could have foreseen when the tales were being told.

Batman began to change almost from the moment he first appeared in Detective Comics #27. While he was introduced as a hero with a gun, that weapon quickly vanished, and his purple gloves were replaced with blue ones that matched his cape and cowl.

But the first major change to Batman came in Detective Comics #38 when the Dark Knight took on his first sidekick, Robin the Boy Wonder. Suddenly, Batman wasn't fighting crime alone, instead, he was paired with a young boy who not only helped in the fights but brought some levity to the hero's life.

While the 1966 movie and TV series Batman usually gets the blame, the goofy tone of the World's Greatest Detective started to happen in the comics well before then. For years, thanks to the crackdown on violence in comics, Batman and Robin spent their time dealing with wild and wacky adventures with aliens and other oddities instead of solving grim crimes.

That all began to change in the 1970s, but it wasn't until Frank Miller's Batman: The Dark Knight Returns in 1986 that the world noticed how much the character had changed. Gone were the "biffs" "pows" and "whams" of the 1960s, in their place was a deadly serious Batman who was ready to take on the scum of Gotham City.

In the story, Joker shot Barbara Gordon, paralyzing her from the waist down and seemingly ending her vigilante career, and then tortures her father all while Batman tries to find a way to bring Joker's madness to an end without killing the villain. The Killing Joke proved to be so popular that it became part of the overall continuity of the comics, leading to Barbara becoming Oracle.

For 54 years, Bruce Wayne was Batman, but that all came to an end in 1993 when the new villain Bane broke his spine in the now-classic story Knightfall. In the story, Bane breaks every one of Batman's foes out of Arkham Asylum, forcing the Dark Knight to work 24/7 to recapture them. When Batman was at his weakest, Bane struck, attacking the hero in the Batcave and breaking his back.

This story led Jean-Paul Valley, better known as Azrael, to take up the mantle of Batman, bringing the character to a darker place than he had ever been before. The ramifications of Knightfall can still be felt in the comics today.
