First appearance: Batman
Year: 1943
Looks like: A dude in a suit who digs bats, duh.

Batman's steez is all about good branding. From the start, everything he used was the "Bat-something." The Batcave. The Batmobile. All of that. Translating it from the comics to film proved to be a bit campy, until Tim Burton's version brought him back to his darker roots... and then George Clooney's Batman got nipples. However, Christopher Nolan's reimagined Dark Knight went leaps and bounds further into costume design, especially in The Dark Knight, where Batman's kit is outfitted to make him more mobile, resulting in a costume that's part S.W.A.T. team, and part street goth.
