"I made a promise on the grave of my parents that I would rid this city of the evil that took their lives. By day, I am Bruce Wayne, billionaire philanthropist. At night, criminals, a cowardly and superstitious lot, call me... Batman."
Batman hasn't always been alone though. With Alfred by his side in the Batcave, Batman has trained a handful of sidekicks known as Robins. Dick Grayson that went on to become Nightwing, Jason Todd / Red Hood, Tim Drake / Red Robin and his own son Damien Wayne.
Over time the Bat-family has grown even larger with people like Batgirl, Batwoman and many other joining the cause.
He even has several allies around Gotham including Commissioner Gordon and Black Canary that will come to his aid whenever needed.
Based off of the Arkham City Video Game, this Batman is a Leader for the Batman faction.
