Nightmare (batgirl/batman)

Years and years and years ago let's just say a very long time ago gothem was in bad shape villains taking over the town two-face ending people's life's in a flip of is coin, joker playing mean jokes on the towns people with is shake hand zapper and the jokers laugh gas..... Cat-women clawing peoples windows or doors stealing money from poor people leaving with not a trace that anything happened.... Penguin leaving exploding sharks and squids in the ocean seas of Gothem.... Riddler leaving riddles all over town and threaten to kill / murder or steal from the rich......
When Wayne inter got stolen by Mr. Freeze and when freeze killed Bruce Wayne he just took over like he was Mr.wayne him self..... Every time he looks at the window by his office he just laughs cause that's how he killed Bruce..... He always says no Bruce no batman cause when Bruce disappeared so did batman ......
