(MAJOR SPOILERS) (was asked by a friend to get this story out of my head and onto paper. Hope you guyys like it, I'll tryy to keep this story as factual as possible to the real Arkham city) (taking place after the surprise ending of Harley Quinn's revenge DLC)

Prologue

At a press conference held by Bruce Wayne to declare his opposition to Arkham City, Wayne is arrested by Hugo Strange's TYGER mercenaries and is himself imprisoned in Arkham City. Strange discloses his knowledge of Wayne's dual identity as Batman before releasing him into the criminal populace. While Strange prepares for the commencement of Protocol 10, Wayne obtains his crime-fighting equipment via airdrop by Alfred Pennyworth, allowing Wayne to become Batman. As Batman, he is first forced to save Catwoman from being executed by Two-Face who hopes to gain respect with her murder. After an assassination attempt on Catwoman by the Joker, Batman tracks the Clown Prince of Crime to his hideout in the Sionis Steelworks, believing he may know the truth behind Protocol 10.

Batman learns from Joker's doctor that the unstable properties of the Titan formula are mutating in Joker's blood, gradually eating away at his body and killing him. The Joker captures Batman and performs a blood transfusion on him infecting him with the same fatal disease. Batman is forced to find a cure for himself and Joker, or they will both perish. Batman is informed that Mr. Freeze had been developing a cure but has since been kidnapped by the Penguin.

Batman pursues Penguin to the Cyrus Pinkney National History Institute: defeating his forces, his imprisoned monster Solomon Grundy, and ultimately the Penguin himself, before liberating Mr. Freeze. Freeze tells Batman that he has already developed the cure, but its instability renders it useless. Batman deduces that the restorative properties within the blood of Rā's al Ghūl can complete the cure. Batman tracks one of Rā's al Ghūl's assassins to his lair in Wonder City, leading Batman into a confrontation with Rā's and his daughter Talia — Batman's former lover. With Rā's al Ghūl's blood, Freeze is able to develop a vial of working cure, but it is stolen by Harley Quinn before Batman can use it.

Batman returns to the Joker and finds him to be fully healed. While Batman and Joker fight, Protocol 10 is activated — A scheme to wipe out the entire population of Arkham City, destroying the criminal element of Gotham. The TYGER troops begin mass executions of prisoners, and Strange launches missile strikes from his base in Wonder Tower. A missile hits the steelworks, burying Batman under rubble. Before Joker can take advantage of the situation, Talia arrives and offers him immortality in exchange for sparing Batman's life. After Batman escapes with the help of Catwoman, Batman is convinced to put an end to Protocol 10 before pursuing Talia and Joker.

Batman infiltrates Wonder Tower and disables Protocol 10. Rā's al Ghūl is revealed to be the mastermind behind Arkham City, and mortally wounds Strange for failing to defeat Batman. With his dying breath, Strange activates Protocol 11 - Wonder Tower's self destruction. Batman and Rā's escape and Rā's commits suicide rather than risk capture. Joker contacts Batman, threatening to kill Talia unless Batman comes to the Monarch Theater. As Batman arrives, Joker demands the cure. Talia takes advantage of the Joker's momentary distraction and kills him. Talia then reveals that she has the cure, having intercepted it from Quinn, but she is killed by the real and still dying Joker. The second Joker is revealed to be Clayface, who had been masquerading as the healed Joker at the ailing villain's request.

Batman incapacitates Clayface, but Joker blows up the theater floor, sending Batman plummeting into Wonder City below. Batman destroys Rā's rejuvenating Lazarus Pit before the Joker can use it, and drinks a portion of the antidote. Batman debates curing his foe, but is attacked by the Joker, causing the antidote vial to smash. Batman maintains that in spite of everything Joker has done, he would have saved him. Joker finally succumbs to his illness and dies. Batman carries Joker's body out of Arkham City into the winter dawn.

The Clown Princess and The Dark Knight

Intro: Weeks after Joker's death Batman is called back to the front line after a call came in that Harley Quinn captured police officers attempting to clear the area. After a long night of taking down rooms of armed henchman and diffusing bombs Batman manages all but one bomb. He and a struggling Harley dive out of the building as the bomb explodes. The super-criminal Harley Quinn is defeated when Robin saves the captured police men, the lead that sent Batman back into Arkham City in the first place. In a last ditch attempt, Harley pulls out a knife and attempts to stab Batman in the back. After the attack is deflected by Gordon, Harley unconscious, and Robin emerges from the ruin safely Batman grapples into the night. Robin and Gordon discuss Batman's health but both are clueless as to what really goes on in his mind.

Batman took to the sky, glancing briefly back down to Robin and Gordon. Most likely discussing the next steps, what would happen to the bat once Arkham was contained and life went back to normal. A title had yet to be assigned odd the dark knights odd behavior since the death of Joker and Talia. He had to meet with Gordon to talk, but to say something came up was an understated fact. Was it so wrong to be mournful of those whose lives were lost? No matter how evil they had become, or the decisions they made that lead them to there demise? He had asked himself these questions over and over again, until he had finally decided no one needed to know the emptyness he felt over there absence. There relationship if any had always needed a certain balance, one not existing without the other. Living to foil each other plans, but neither winning nor losing. But could this even be considered a victory? The fact Harley Quinn had just attempted to kill him answered this, it was finally over. Speaking of Harley, Batman landed on the nearest billboard headed back to the steel mill. Had he honestly been as careless to leave her unconscious with Gordon? Looking down over the edge of the building, he took in the site, the fires still burning feverishly, Robin and Gordon perched on a piece of debris. From what he see,they sat completely silent as if taking in everything something he had been dying to do for weeks. Quinn, that's why he was back here but there was no sign of the distraught girlfriend of the Joker in the area. With a deep sigh he rose back to his feet, deciding he would deal with her later.

As if on cue she appeared placing her hands on her hips;

"Hey B-Man" she said, almost whispering.

" Quinn what are you doing here." Batman said flatly. Debating between apprehending her and hearing her out he finally settled on listening, of course keeping a plan to counter attack at the ready. He took her in streaks of light blonde fading through her black hair, her torn clothes, and black netted veil. Harley stood silently head hanging down, staring at the cuts and dirt on her hands. "Quinn" Batman repeated, as the frail girl finally raised her head to look at him. It was hard to believe when he really thought about it, that behind those sapphire eyes and running mascara was a psychopath.

"I never really saw it until now" she said, allowing herself to giggle a bit."Jokah, he lives through you. You didn't let me die, you didn't let me burn in that building. Because Mr.J wouldn't have let me" Harley chirped "Because he's still here. In you".

Taken aback by her claims he sprung forward gripping her wrist, her eyes widening but her feet planted firmly on the concrete.

"You never were very bright." he grumbled. Once again the silence fell over them, it wasn't like him to waste time with conversation. Batman couldn't help but feel connected to Harley in someways, both grieving the loss off a person who never did anything but hurt them, and being the only other person who understood the others pain here. Finally he took a step back dropping her wrist.

"Get out of here". Sparing her was the only thing he could think to do, just hope that she would be smart enough to see the opportunity and run. She raised her head, that signature smile on her face "you letting me go bat brain?". Within a second the gap between them closed, Harley arms locking around his neck and her lips pressing against his. Batman, the dark knight, had definitely not been himself for a long while. But this? He could have pushed her off, arrested her, or even fought back. Instead he let the moment take him over for a second to long before shoving her backward toward the edge of the building. With another fit of giggles, a wink, and a backflip that led into what seemed midair Harley Quinn had escaped yet again.

After punching a good size hole into the concrete below him, he realized Oracle was practically yelling "BruceBruce". "Oracle" He said as composed as he could manage.

"Did I just hear Quinn LAUGHING, Tim said you got out and had Quinn in custody..." she trailed on.

"You heard Quinn" he said, cutting her off. "I...why was Quinn... Nevermind. Cat-women was just spotted getting the last of her loot. Might wanna get over there and get the arrest. Unless you have some kind of problem with that". Barbra was alwayys very smart, must have finally hacked the tiger security cameras and saw everything.

" Nope no problem Oracle, take it you've got those tiger security cameras online?" She sighed "Copy that, get the bitch and get out of there Bruce".
