↳ Jason Todd as Batman (New Earth)

With the apparent death of Batman, a power vacuum formed for the premier crime fighting vigilante in Gotham City. Jason Todd quickly rose to be the new Batman, albeit a gun-wielding and murderous one. Todd manages to battle and conquer the entire Bat Family, except Dick Grayson as Nightwing, who successfully defeated him and relieved him of the Batman mantle.
