Comic book writer Grant Morrison said it best: “[Every bat-suit is] completely different” – sometimes insanely different – “but they’re all instantly recognizable as [the-bat-suit].”
Unlike Superman, who has more or less been wearing the same blue and red strongman since Action Comics #1 in 1938, Batman just keeps changing his appearance every few years to keep up with the times. Basically, he’s the Madonna of superheroes.
