Villains: Bane, Harley Quinn, Joker
Story: Batman and Robin are finally getting their first breath of relaxation after saving the city. It's only ben 3 weeks since the last fight with Joker and Batman has been training Robin more in hopes that he can actually survive in combat against Harley and The Joker. Robin is being reckless, and obnoxious during his training and Batman has this look on his face like "why did i ever get a partner?". After Robin completes his training for the day, Batman scolds him on how he needs to improve, saying he wouldn't last a night alone in Gotham.
Meanwhile, after Harley sneaks back into Arkham and is using acrobatic skills to stay hidden she asks a prisoner where Joker's cell is. The prisoner justs laughs in her face and yells " Hey guard, i don't what is going on here but there's someone here crazier than me looking for the Joker". As the guard draws nearer, she realizes her fatal mistake and quickly hides herself. She waits until night to break The Joker out. She sneaks back into her old room at night and steals files from the new nurse on where the Joker is located. When this new nurse see's her, Harley beats her over the head with what looks like a giant wooden mallet. On the news it shows stories of a refugee prisoner wearing a helmet connected to tubes on his back. They say the man has become increasingly dangerous and must be stopped at all costs. Cut to Bane in his new makeshift lair, filled with stacks of money, jewelry and the mysterious substance with a label that says "venom". He is shown telling some gang members about an intricate plan of his to bring Gotham back to control of smaller gangs rather than the mob. His first order of business is to take out Batman. As the gang members walk out of the building they see a mysterious person holdng a whip saying, " you did good boys".
Cut to Batman training Robin even more to the point of physical exhauston. After the same finish up-and-scold routine, Robin asks Alfred why Batman has a stick up his ass. Alfred says he went through the same traning you are, and he's trying to get you to become more responsible for your actions as a hero. Robin still doesn't get it, and leaves the room angry and frustrated. Cut to Harley walking up to the Joker's cell. She says "Hey boss" and he says "Harley, is that you? Get me out of here please or else i'll die by laughter". She says "Sure Thing" and she breaks open his dor to see him in a strait jacket. She unties him and they sneak out. Next Morning, Arkham is ripe with detectves, guards and policemen all looking for some clue of how the Joker got out. None of them have an idea when suddenly, Batman shows up to scan the place himself. He sees mysterious footprints and similar to Shawshank Redempton, He sees a hole in the wall. The news shows up after a few hours warning people to keep off the streets, as the Joker and Harley are loose again. As a couple watches the news, The Joker is shown from behind slitting their throats then Harley grabs the bleeding bodies and puts them in a trashbag. They make a new hideout and then they cackle with laughter.
Meanwhile, we see a shadowy figure stalkng Bane as he wanders the dark alley ways. The shadowty figure says,"interesting", after she sees Bane walk into a mysterious building. She decides to crash the party and Bane says "Who are you? she says "I'm Catwoman" and she then proceeds to attack him. After a little struggle, he finally grabs her and throws her out of a window leaving her covered in cuts and bruises. Bane and the messenger for someone else leaves the premesis as Catwoman struggles to get back up. As far as everyone else knows, Catwoman no longer exists. She manages to be able to put away her costume and she walks towards a police station.
Meanwhile, Batman and Robin are out searching the night for Joker and Harley and they come up wth nothing. Robin says he's sick of looking for easily beaten two-bit criminals when Batman tackles him to the ground and yells in his face about what The Joker has done to Gotham. Robin gets up and says he quits the "vigilante business" and then he leaves, heading out to find his own place. Batman is angered to a point where he doesn't even notice the gang member sneaking up on him. The gang member stabs at him with a knife when Batman flips him over and says "who sent you!". He says Bane dd and that Bane is in negotations to work with the Joker in bringing the city back to gang control. He also tells Batman the story of Catwoman coming back. He immedately heads to Selina Kyle's place to make sure she's alright. It shows Selina covered in minor bruises and scars. She tells Batman it was nothing major and she could've easily handled Bane for good. She said she learned somethng of a gang that Bane was bringing together with someone else. Batman realizs what is going on and decides she must come along and fight too. They quickly devise a plan on how to get rid of Bane and Joker once and for all. Cut to Robin walking an alleyway when Joker sees him and says "Hey i can offer you a lifetime deal if you work for me". Robin, at this point easily covinced, says okay.
