One of the more interesting news stories to come out of Comic-Con last week involves the return of Batman’s classic costume. As of Batman #53 next month, the Caped Crusader will be back in his pre-Flashpoint costume, external underwear and all. This comes just a couple months after Superman brought back his red trunks. While these might seem like an unimportant, superficial changes to iconic characters, these costume overhauls actually represent a significant change in DC’s approach to superhero storytelling.
