The Bat is back... way back.
Before Batman became The Dark Knight that Gotham City revered, he was merely a vigilante in a cosplay outfit throwing around gadgets with funny names and chasing one particular cat-shaped woman. Or at least that's what Gordon thought of him, and maybe even Alfred. Bruce Wayne eventually convinces both that he is on the side of justice, and that the city needs him to control the ever-growing number of crazy villians, though Gordon believes it's him who attracts their attention. I believe he has a point there, but nonetheless, Batman: Arkham Origins explores Batman's growth and purpose as he matures into the spiky-eared badass fans know and love.
