I do not own RWBY or Batman.

"Welcome to the madhouse, Batman! I set a trap, and you sprang it gloriously!"

-Chapter 1: The Madhouse-

It was another rainy day in Gotham City. The large metropolis was an average city by day, with normal citizens moving at their own pace, going to and fro between jobs and homes, places of public and private, and so on and so forth.

But by night? It was a gloomy, hellish nightmare. An almost literal cesspit for dangerous criminals to grow and fester beneath the luxurious lights of the city. Preying on the innocent as they stole and mugged, beaten and bruised, killed or even raped their victims before leaving their bodies, whether they were breathing or not, in puddles of water and their own blood.

As for this night, another criminal, a psychopath of a man who has killed nearly more than any other murderer in their entire lifetimes combined, was in the process of being sent back to whence he came.

A facility for the mentally ill: Arkham Asylum.

But as for now, let us focus on another lawbreaker, a more... recent criminal, if I might say. Someone who is relatively new to our beloved Gotham City.

"I keep telling you, I'm innocent! I don't even know how I got here!" the girl yelled from the back seat of a police car, this girl had pale skin with wavy black hair trailing down to her back, along with a pair of amber eyes that shone through the darkness of the vehicle. This girl was recently arrested and was on her way to the GCPD cells.

"I said shut up back there! Do you even understand what the 'right to remain silent' means?! Besides, you nearly cut off one of our boy's head off with that large kitchen knife of yours, that's assualt and battery and attempted murder in my books. You're very lucky he still has his head on his shoulders, otherwise we wouldn't be in this situation!" a rather portly and irritated officer, who was sitting in the passenger seat, yelled at the girl, but she still maintained her composure: continuing to glare at the man despite her plea.

The large man had receding grey-black hair, a poorly shaven face, which looked as though it was contorted into a permanent scowl. He wore a dark brown duster coat, along with a black vest and white buttoned shirt under it.

"Calm down, Bullock. We can take care of this when we get to the back to headquarters," the driver tried calming him down. The driver had white hair, clearly he was aged as well as the man next to him, maybe even more. Stress lines ran across his forehead and a pair of brown glasses covered his eyes, he wore a grey vest and white long-sleeved shirt, a pistol hung by the straps on his torso.

"Headquarters my ass, Gordon, I say we kick her off and let some Crazy lynch her or something. No one messes with the GCPD," 'Bullock' protested, pointing a thumb at the girl.

"She's just a kid, Harvey."

"She's... what? Eighteen? Nineteen? How old are you, kid?" Bullock leaned over to get a better view of the girl.

"Seventeen, and just so you both know, I'm right here," she deadpanned, rolling her eyes.

"Ah shit, not old enough for prison then. Guess we'll have to settle for a youth facility or somethin'. By the way, what's your name?" the large officer asked.

"Why do you want to know?" the black-haired girl asked, shifting uncomfortably in her seat due to the handcuffs that held her hands behind her back.

"Christ, kid, I'm just bein' friendly for now. Let's start over: I'm Officer Harvey Bullock, I enjoy long walks on the beach and arresting crooks; and this lump here is Commissioner Jim Gordon," Bullock quipped as he jokingly pointed to the Commissioner.

"Lump?"

"Yeah, couldn't come up with anything clever," he shrugged.

"Blake, my name is Blake Belladonna?" she answered neutrally, earning a nod from Gordon.

"Belladonna huh? You uh... you one of those 'social workers' or something?" Bullock asked as he raised an eyebrow, earning a fierce glare from the girl.

"I was born with that name," Blake growled.

"Calm down kiddo, I was just assumin', given the getup you're wearin'," he motioned to the clothes she was wearing. Blake looked down to see that they were the clothes that she has always worn.

"I guess it's a little... revealing," she observed.

"Ya got that right. Something like that might send some mixed messages to someone or other," the car stopped for a second, Commissioner Gordon pulled out a small, yet bulky and antique-looking laptop, and set it on his lap and began typing on it.

"Where's Gambol Shroud?" Blake suddenly asked.

"What the what?"

"My sword? Where?" she demanded.

"Oh yeah, that sharp sunovabitch? It's in the trunk, but you ain't gettin' it just yet-"

"Hey Harvey?" Jim interrupted.

"Yeah, Jim?"

"Look at this, I think there's something wrong," the younger of the two asked, despite them both being older men.

After several seconds of Bullock's running up and down at the computer, he stopped and stared at the screen in confusion and shock.

"Nothing, no ID," Bullock whispered.

"Absolutely nothing," Gordon confirmed, he then turned and looked at the girl.

"Do you know where we are?" he asked, she shook her head.

"Ever heard of Gotham City?" Bullock asked.

"No."

The two officers looked at each other again before turning back to the confused girl.

"Metropolis? Keystone City? Starling?" Bullock continued

"No," Blake repeated.

"Then where do you think you are?" Gordon asked suspiciously.

"Remnant, but certainly not any of the cities in the four kingdoms look anything like this place. It... honestly looks gloomy," she answered in a monotone voice as though the things she was saying were normal.

After a few seconds of silence, the larger of the two then coughed into his fist.

"Well, Jim. We either got an illegal here with a perfect American accent, or we're gonna need to talk to you-know-who about you-know-here," the car turned finally started again and continued it's drive.

What were they talking about, it sounded as though they were not on Remnant, unless...

No, that can't be possible! There's no way that this could happen! Then again, the city she was in was not familiar to her, these two dressed similarly to normal law enforcement but with no familiar insignia to specify what kingdom they were a part of. They talked differently, the things they said was very foreign to her; Gotham? What kind of name for a city was that?

She didn't know what to think at this point.

"Where is he anyway?" the Commissioner asked, his eyes still staring to the road in concentration.

Suddenly out of pure coincidence, the radio sparked to life, a female authoritative voice resonating from it.

"All units, proceed to Gotham City Hall. The Joker has been apprehended. Batman is now en route to Arkham Island," the radio then shut off.

"There's your answer, buddy. Come on, let's head to the nuthouse," Bullock said.

"Already on it," the car continued it's pace towards this island.

"What's going on? Who's this 'Joker'? Who's 'Batma-'"

"Oh shit, speed bump!" the larger officer yelled, the car tried to slow down at the oncoming bump in the road, but it still managed to make a small bounce, the car stopping for just a second.

"Ah!" Blake yelped as she flew from her seat and hit the ceiling of the car with a thump.

"Oh shit, I forgot they put that there last week. My bad, kid, you okay..." Bullock's voice trailed off as he stared at the girl.

No, not at the girl. Above her.

It took a second for her to realize that when she hit the top of the car, a loose piece of metal snagged onto her bow, pulling it way from her head.

Time nearly froze as Bullock and Gordon stared at the pair of cat ears on her head, her face blushing wildly as it also changed from it's former stoic demeanor to one of panic and fear.

"Ahem... uh, Selina Kyle's gonna wanna see this too," Bullock quietly quipped, gulping in shock at the same time.

"Uh huh," Gordon grunted in confirmation.

"Don't. Tell. Anyone!" she hissed in anger.

"Woah, calm down, kitty-cat!-" Blake glared as Bullock said that.

"-You may not exactly be social norm, but we've. Seen. Worse," he continued as they both looked up, the police car was now in the process of passing through a black iron gate with two shrouded statues holding lanterns, labeled 'Arkham Asylum'. Chills ran up the Faunus' spine as soon as she caught sight of the towering structures. The place was huge, a gothic feel to it as her eyes caught sight of a large clock-tower-esque building, a shorter building, and a botanical garden just off to the other side.

After parking the police car next to a string of similar cars in a parking lot, they got out of the car, Gordon opening the back door and grabbing Blake by the arm and helping her to her feet, he grabbed the bow that was still stuck on piece of metal on top and tied the same bow back onto her head, although a little crudely.

"You're taking her with you?" Bullock raised an eyebrow.

"Yeah, I have a feeling that she'll get out somehow if I just leave her; also, give me the sword," Gordon held out his hand, Blake turned her head to look at him with a look of concern.

"Why?" he asked uncomfortably.

"I need to ask Batman to see it, then we're putting it in the evidence locker. Besides, I know you would sell it at an auction if you were given the opportunity," Gordon watched as the larger man chuckled and tipped his hat to him.

"All good points, Jim-bo," Bullock opened the trunk and handed the oversized blade to the Commissioner, who held the blade in his hands.

"Holy shit, that sword's got a gun on it!" the officer shouted.

Gordon looked down to see that, as pointed out by Bullock, that a pistol acted as it's hilt.

"Batman's going to have a field day with this," Gordon remarked as he lead the girl to the entrance of the Asylum, which proceeded to hiss and slid open, revealing a long brick hallway filled with windows and guards holding assault rifles in their hands.

What kind of asylum needs this many guards? Blake thought to herself, surprised by the quantity of guards that guarded this one entrance.

"You can go Bullock, I can take it from here," he told the man.

"Really? Don't think I can handle it?" the larger cop raised an eyebrow in concern.

"No, you need to explain why we're gonna be taking so long," Gordon answered.

"Alright, I'll see ya soon. I'll even crack a few skulls for you while I'm at it," Bullock waved as he turned and left the Asylum.

"Now he's gone," Blake sighed in relief.

"Don't like him?"

"He's... I don't even know what to think of him," she admitted.

"Eh, he grows on you eventually," the two continued walking until they reached the other side of the hallway, where they met a man in a different uniform, a rifle in his hands. The man had a buzz cut, along with a slash along his left eye, rendering it blind. It eerily reminded Blake of Weiss' scar, but other than that, the similarities stopped there.

"Officer Boles," Gordon said.

"Commissioner Gordon," 'Boles' responded.

"I'm here to speak with Batman," Gordon explained.

"You're early, go on ahead and wait for him there," he motioned to the door behind him before stopping Blake.

"And what do we have here?" Boles raised an eyebrow in suspicion.

"The reason why I have to talk to him," the Commissioner answered for the Faunus girl.

"And what would that reason be?" the other man raised an eyebrow.

"She was just recently accused of a crime, I need to talk to Batman because of it," Gordon explained, telling a half-truth. She was accused of attacking a fellow officer, but then again, Batman would know why a girl suddenly appeared in strange, yet provocative clothing, wielding a large sword that most likely seconded as a gun by the look of the hilt.

"Looking to clear her name? What about that oversized toothpick you got there?" he asked, motioning to the weapon that Gordon was holding.

"Something like that."

"Well, you go on ahead. If she's been accused of a crime at the moment, then she'll see the Bat as soon as he comes. I'll keep an eye on her, trust me," he motioned to the door on the opposite side of the hallway.

Gordon looked to Boles with a hard stare, then to Blake, who gave him a slight nod. The Commissioner then straightened himself up.

"Very well then. Don't try anything funny," he warned, Boles nodded reluctantly and let the man pass through the door, still gripping the large sword as the next few guards gave him an uneasy look, but he told quickly gave a brief summary of the situation.

While the other guards weren't looking, Boles slipped out a flask and took a quick sip before returning it to it's hidden location, but Blake caught sight of the act.

"Drinking on the job?" Blake raised an eyebrow, giving him a suspicious look.

"Hey kid, you tell anyone, I'll make sure you're never found again," he growled, his more formal demeanor gone, now replaced by a more aggressive personality and grabbed her by the handcuffs and lifted them higher, sending a short feeling of pain through Blake's arms, causing her to wince and glare at the man.

"So be it," she continued glaring, then rolled her eyes as she stood next to the man who had finally let go of her.

They waited for the next few seconds in silence before another man came out of the room. A short, aged balding man wearing a black business suit, a red tie and flower on his suit, resting both of his hands on a cane. The rose suddenly reminding Blake of Ruby.

Oh how she now missed her friends so much right now, the same people who accepted her as a Faunus and former member of the White Fang. What did she do wrong to get caught up in this mess?! Was this a sort of trick that some sick, demented deity decided to pull on her?

"Warden Sharp," Boles greeted, nodding his head slightly.

"Officer Francis Boles," the old man simply said, he then turned to see the amber-eyed girl with her hands cuffed behind her back.

"Blake, Blake Belladonna," she said.

"Pleasure to meet you," he said, bowing his head slightly, "The handcuffs?"

"Commissioner Gordon thought that I had to stay with these on," Blake explained, shaking the handcuffs, giving off a rattling sound.

"He suspects that you'll break out?"

Blake gave the man a look of slight, almost unnoticeable amusement, "I'm full of surprises."

The Warden raised an eyebrow before looking back at the door.

"So... Arkham Asylum?"

"Yes, Arkham Asylum, this facility has stood on this island for nearly a century. Constantly being renovated and refurnished until it became the modern marvel you see today," Warden gave a brief history of the building that they were inside of.

"Why does this place need so many guards?" she finally decided to ask.

"Some of our longer-term patients are... different from the rest. Special, to put it lightly," the Warden answered.

Suddenly, the green lights on the doors began blinking, causing the locks to unlatch and retract, the doors finally opened, revealing something Blake was very unprepared for.

Before her, standing on the opposite side of the room, was a large man dressed in a black and grey suit, showing off his muscles that covered his body, a cape billowing from the wind that blew by. Behind him was a black car shining a bright light behind him

The most strangest thing about him was his head. Upon it was a cowl that covered a majority of his face, on top was a pair of black ears resembling bat ears.

Blake couldn't tell if this was either a Faunus vigilante or a human dressing up in the most intimidating bat costume anyone has ever seen.

She was going to guess that this was the 'Batman'.

What unnerved her was what was next to him. To his left was a thin man with green hair, extremely pale skin (enough to rival Weiss' skin color, or lack of color), and blood red lips that curled up into a smile. He wore a purple pinstripe suit with a pair of black pointed shoes. This was who she guessed as 'the Joker'.

This Batman wore a face of anger as he picked up the Joker by the arm and began leading him to the other side of the hallway, the guards suddenly had their guns trained on this 'Joker'. He looked creepy, but he didn't look all that threatening, what kind of crimes was he convicted of? Missing some kid's birthday party?

A chill ran up her spine as she heard him giggle maliciously.

"Hey, Sharpie! Love what you've done with the place!" Blake flinched at the sound of his voice, it sounded so... demented.

"That's Warden Sharp to you," the Warden said, turning to the man behind him, "Boles."

The Arkham guard walked menacingly over to the Joker.

"Yo, Frank-ay. How's the wife and kids? Ya miss me?" the Joker asked mockingly before being hoisted up by the collar of his purple suit.

"Shut it, clown! A lot of people here really want to talk to you," he growled, grabbing the pale-faced criminal by the arm and onto a stretcher.

Blake watched as Batman looked at her and the fact that she was wearing cuffs, then gave her a fierce glare.

"Why is she here?" his deep voice catching Blake off-guard again as he asked the Warden.

"She is here under the jurisdiction of Commissioner Gordon," the Warden answered.

"He also wants to talk to you about her, dunno why though," Boles explained.

"Really, I don't mind walking," the Joker said, his grin still plastered on his face as he was still being strapped to the stretcher, "Not so tight, boys. You'll crease the suit."

Then he turned his head to look at her, "Hello there... kitty cat. Hey Frankie, I thought you said you were done with 'scared straight' programs. Look at her... you'll scare the poor girl," he said darkly before tossing his head back and laughing maniacally.

In all honesty, that smile and cackle terrified Blake. It was as though he was a creature of Grimm in human form. Cruel, unrelenting, sadistic, these words were beyond the description of this man, she had gone from assuming he was a common crook to a terrifying nightmare in less than five minutes.

Then she suddenly realized something that the man had just said.

'Kitty cat...' he had said.

Did he know that she was a Faunus? And how? The bow was still on her head, in fact, no one even noticed the bow on her head.

"Get that filthy degenerate out of here," Warden Sharp ordered. For a second, Blake nearly glared at him, almost as though he was referring to her. The tone he spoke in reminded her so much of Weiss.

"Warden, something's not right, I'm going with him," Batman said.

"Yes yes, but please bring the girl with you as well. I hope she does not cause too much trouble," Sharp cautioned.

The hard glare that Batman gave her nearly made her jump in fright, it was as though those eyes were staring into her soul.

"She won't," he finally said, still looking at her.

"Walk," Batman commanded harshly, she wanted to yell at him, scream, at least try to hit him, but those eyes restrained her from doing so. So she reluctantly obeyed, walking ahead of this bat-eared vigilante.

As Blake walked through the door, she took notice of the large room filled with guards and the small building in the center.

"Is Commissioner Gordon here yet?" he asked one of the guards as he passed through the door.

"The Warden just told you that I was here because of the Commissioner and that he wants to talk to you, what do you think?" she finally managed to sarcastically reply, but was answered by the same glare that immediately shut her up before.

"Quiet," he ordered in a dark tone, she nodded slowly, gulping in fear.

"Yes sir, he's, err, waiting for you down at Patient Handover. He got here just before you did," the guard replied.

"Sharpie loves his cameras! Hey Sharpie, you getting my good side? Ah the heck, they're all good aren't they? Why don't you give a shot or two to the lady before I do!" the clown in the purple suit giggled maniacally. Blake then had to avert her eyes from the bright lights that suddenly turned on.

"Who is this guy?" she asked Batman, who then faced her.

"The Joker, a criminal mastermind who has killed dozens, if not hundreds of innocent people," he answered.

"He doesn't look much like a 'mastermind' to me," Blake whispered as she observed the criminal's behavior.

"Look at all this new security. How's a guy supposed to break out of here?" the Joker wondered out loud, still strapped to the stretcher.

"That's part of his act. Luckily, you won't have to see it," he said as they descended down to the lower floor on an elevator-like machine.

"I want him securely locked away this time. Another escape and I will lose support for my mayoral campaign," they heard the Warden say as he continued speaking to another guard. The Faunus rolled her eyes at the dialogue between him and the guard, another human running for politics.

"New patient in the Intensive Treatment lobby. All non-essential staff are to vacate the area," a female voice sounded out as the group entered a small room.

"We're not staff," Blake pointed out to no one in particular.

"We're essential, for the time being," Batman said.

"It's always nice to return to my sweet little haha-hacienda!" the Joker said as he was continually dragged by his stretcher, Blake tried to shake the feeling of dread from her mind as they entered into a smaller room.

"Tunnel's full. Start the scan!" they heard another voice say.

"Scan initializing," another voice said, several machines began scanning the room with cobalt light.

"Y'know what? I prefer the good ol' cavity search. Much more personal. How about you, girlie? Up for a little two-on-one with me and Harley?" Blake didn't even need to guess who said that, grimacing at the man's way of thinking.

The scan began flashing red, letting out a loud beeping sound.

"Multiple prohibited items," the voice said.

"I want Joker searched again!" another voice responded, obviously irritated.

"Err, it's not the patient. It's, err..."

"Ooh! Whatcha sneak in with you, Bats? C'mon, tell me! Batarangs? Batclaws? Bat-snacks?"

"Scan is green on Joker."

"Open the gate! Get him out of there!" the last voice shouted.

"I want weapons on him at all times. Do not let him out of your sight," the door opened to reveal a man with darker skin pointing his own gun at the Joker. Blake noticed that this man had a hook where his left hand should be, she guessed that it was most likely lost in an accident.

"There'll be enough time for you later, Cash. Speaking of time, tick, tock, tick, tock. Is that a crocodile I hear?" he mockingly asked, laughing that same deranged laugh.

"What's up, doc? Counsel me in for tomorrow at four, we got a lot of catching up to do," he said to one of the doctors hiding behind the guards.

The TV in the corner flicked to life, "Hello, new patient. This is Quincy Sharp, Warden of Arkham Asylum-"

"Ooh, it's my favorite show. 'I'm Warden Idiot, you'll never escape!',?" the Joker mocked as he imitated the Warden on the screen before laughing once again.

Off to the side, on the other side of the room, were what appeared to be dozens of prisoners being led by Arkham guards, cheering on the Joker before being silenced by the guards.

What would inmates be doing in a place like this? Blake wondered, then again... no, this had to be Remnant. There has to be a logical explanation to this!

What would happen when her teammates find out she's missing? Again?! What would they do?!

She felt a bump on her shoulder, interrupting the rest of her thoughts. The Faunus looked up to see Batman looking down at her with those cold, impassive eyes.

"Something wrong? You're hyperventilating," he said, proceeding to look up at her bow, as though he knew something that everyone else in the room didn't know, nearly putting her in a state of shock again. For a split second, she saw his eyes turn pure white before they turned back to their eye color.

"I-... I'm fine," Blake noticed that she was, in fact, hyperventilating; she calmed down and tried to resume a calm demeanor.

The tall man merely stared for literally a second before looking back at the other man in the upright stretcher.

"I'm telling you, the state of the wiring in these federal facilities is-well, it's shocking! My boys over there would've been hurt in that... unfortunate fire," he emphasized 'unfortunate' in a false somber-like mood.

The doctor off to the side walked closer to the Joker, "Just gotta check your prisoner, Officer Boles."

"Whatever, just be quick!" he snapped

"Only following procedure. Hmm, patient seems to be in satisfactory condition. Looks like he suffered minor lacerations, probably in the last two hours. There seems to be-"

Everyone, with the exception of Batman, jumped back in fright as the clown screamed and cackled loudly, before returning to a more... 'normal' mood.

"Need to take my temperature? I'd be happy to drop my pants," he offered, giving them the same deluded grin.

Blake cringed at the thought, but she quickly caught on that he was only trying to get in their heads. Even so, he creeped her out.

"He's all yours, get him out of here!"

"He's good, get the door open," one of the guards yelled, also keeping an eye trained on the girl walking in front of Batman.

"Alert in Intensive Treatment," the voice said through the mics on the walls, "Category 9 patient in transit. Pacification system active, shoot to kill permissions granted."

Category 9? Shoot to kill? What kind of mental facility was this?

"You heard the lady. We got another psycho on the way!" another guard shouted, the creaky sounds of an old elevator ascending.

"Can you smell the excitement in the air? No? Must've been one of the guards-"

Blake watched in pure horror as something big, really big, emerged from the old elevator, having to crouch to even fit inside the old machine.

This beast was dressed only in orange pants, it's body was covered in green and grey scaly skin.

"-Croc, old boy! Is that you!?" the Joker turned to see the beast that was being carried by the old, creaking elevator.

Was this another Faunus? She had heard of rumors of reptilian Faunus in other parts of the four kingdoms, but she had never seen one up close before.

"Get ready, keep your weapons trained on him at all times," one of the guards commanded.

"He looks angry," a guard whispered.

The reptilian thing pushed itself out of the elevator with it's large muscular arms before standing up at full height, a light shined on it(him?) as it rose. She noticed that this crocodile creature's teeth was showing through it's own mouth, giving off a more intimidating appearance.

"That thing looks pissed," another said, his gun pointed at the 'patient'.

Then it did something strange. This 'Croc's' head shot up and began sniffing the air before turning to face Batman and the Faunus before rearing it's head at them.

"What's it doing?"

"I've got your scent, Batman. I will hunt you down," he spoke in a dark, dry and scratchy voice before the collar around his neck lit up, causing him to growl in pain as electricity coursed through his neck.

"A toy collar won't keep me from killing you, Batman. I will rip you apart, eat your bones," Croc threatened as he was lead away from the guards before stopping.

"I smell... a cat in here," he finally said, taking one last intimidating look at Blake before walking away.

"Jesus, what the hell was he talking about? A cat?" one of the guards asked, one of the others just shrugged.

"That reminds me, I really need to get me some new shoes," the Joker finally said as he wiggled his shoes to prove his point.

"What... was that?" Blake asked the man beside her.

"Waylon Jones, also known as Killer Croc. Born with a condition that gave him a reptilian appearance, commonly convicted for murder and... cannibalism," Batman explained as they walked towards the elevator.

So he wasn't a Faunus... just a beast of a man.

"Wee! Great night for a party!" the clown squealed in sick delight as they descended inside the elevator.

"Not where you're going."

"The night is young, Bats. I still have a trick or two up my sleeve. I mean, don't you think it's a little funny how a fire at Blackgate caused hundreds of my men to be moved here?" he asked before chuckling quietly.

"I thought I told you to stay quiet!" Boles yelled, shaking the gun in his arms threateningly.

"Oh Frankie, you really should learn to keep that fat mouth or yours shut. It'll get you into trouble," the Clown warned.

"Tell me something. You've never let me catch you this easily. What are you really after?" Batman demanded, Blake listened closely for what the Joker was about to say.

"Oh nothing much, Hundreds dying in pain and fear. All their meaningless lives brought to a horrifying conclusion. All thanks to you and a book of matches. Was that the answer you wanted?"

Blake heard the Warden on the television continue to speak, but she tuned out his voice as she tried to understand what this guy was talking about. It was almost as though he wanted to be he-

She jumped back in fright as the Joker suddenly burst out laughing as the lights suddenly went out, watching as the two guards nearly panicked as they tried to see in the dark.

"What's he doing!?"

"Stay where you are!"

"Get a flashlight! Get a light on him!"

His deranged laugh was cut off by a choking sound, she looked through the dark with her night vision to see Batman's hand tightly wrapped against Joker's windpipe.

The light flickered back to life as the guards then caught sight of Batman with his hand around Joker's throat, the TV resuming it's recording of the Warden.

"What? Don't you trust me?" the clown managed to say through his cut-off air supply before the bat-eared man slammed him against the stretcher.

The elevator door opened, letting Blake, Batman, the guards, and Joker leave.

"Our guest has arrived," the guard said.

"Intensive Treatment lower floors are now at level Red Alpha," the feminine voice spoke.

"So, you're back. You killed three of my crew when you busted outta here," another guard spoke to Joker as they walked through another door and continued down a long hallway.

"Only three? Hah! I'll be sure to try harder next time, what say we aim for a hundred!"

Blake finally caught sight of the Commissioner signing something on a clipboard.

"Long night, Jim?" Batman asked.

"Heh, Joker invades City Hall and holds the Mayor hostage, leaving it to me down here to juggle the SWAT Teams, the media, and you. Yeah, it's been a helluva night," Gordon said as he shook the man's hand.

"Hopefully the last one we'll ever have with him."

"Uh huh, yeah," Gordon said as they continued walking.

"Gordon, Sharp and Boles said something about you wanting to talk to me about her," the Dark Knight looked to Gordon, Blake turned to face the two.

"I'm right here," she deadpanned as she stood right beside them.

"Come on! The adults are talking!" Boles said as he grabbed her by the arm and continued pulling her along with him.

Even though the distance was growing, she still managed to hear with her enhanced hearing, courtesy of her Faunus heritage.

"We found her attacking one of my men, saying it was in self-defense. I talked to him on the phone, surprisingly he's not pressing charges."

"What about it?" Batman asked.

"She kept saying she was innocent, that she had no idea where she was. I spoke with her on the way to Arkham, she has no knowledge of Gotham or how she got here. She kept going on about 'remnants' and 'four kingdoms'. You think it's one of those things happening again?"

"I doubt it, probably another patient," he answered.

"What about this?" Gordon held out Blake's sword in front of Batman, he picked it up and carefully studied it, taking a close look at every detail.

"Lethal and uncommon, but it doesn't prove anything," he handed the sword back to the white-haired man.

The Commissioner buried his face in his hand, "Help me out here, Batman. I know you left Them, but you have to think about the fact that she is not from here."

Batman turned to look at the girl, who quickly looked away at the last second.

So it's true, she's not on Remnant anymore. If so, then where was she?

"The cat ears?" Batman whispered, Blake froze in fear at the mention of the thing that made her different from the people around her.

"How'd you know?" Gordon asked incredulously.

"World's Greatest Detective," he answered.

"Right, right," the Commissioner nodded slowly.

"I'll see what else I can find out, Jim."

"Thanks Batman, you're a real help here," the older man scratched the top of his head with his hand.

The two men finally walked closer to the Joker's stretcher as it finally stopped at an electric gate.

"Hold it there. Sorry Batman, Arkham staff only," the guard standing next to the psychiatrist raised his hand to stop them.

"I assure you, if anyone's qualified, it's-"

"Listen, I appreciate the concern, but he'll unsettle the more violent inmates," he explained.

Blake heard the Joker cackling behind them.

"I think he's talking about you, Bats. Don't be a stranger, you're always welcome here. Gotta say, it's good to be back!" he laughed as he was being pulled by Boles before being passed to the next guard, who led him through the deactivated electric gate.

"You okay?" Gordon asked.

"He surrendered almost without a fight, I don't like it," Batman explained as they walked through another room beside the electric gate, with both Blake and Gordon following close behind.

"At least he's back where he belongs."

"He's right. From what I've heard from you guys, it's almost like he wants to be here," Blake said.

Gordon looked at the girl, "What makes you say that?"

"Batman said Joker never let him catch him this easy and that he surrendered almost without a fight. Doesn't that strike you as a bit suspicious?" she asked as she continued to look through the window.

As though on cue, Joker fell forward. The guard leaned forward and tried to force him to stand on his feet, but the Joker rammed his head against the Arkham guard's head, pushing him away before getting down on his knees. The clown inmate then got up and began suffocating the man with his handcuffs.

"Joker's loose! Alert the Warden!" Batman yelled to one of the guards.

"Hurry! We're losing him, doc!" he cackled as the doctor struggled to help the guard resist the inmate's assault before being knocked down by a kick to the torso.

Blake watched as Batman slammed his fist against the bullet-proof window, creating a large, fist-sized crack in the glass.

The deranged man then began dancing around quickly before pointing to the opposite gate.

"Ta-da! Honey, I'm home!" he said, the gate dissipating as the small neon words on the switch changed to a green 'Unlocked' sign.

Another punch into the glass, causing the cracks to further move up the window. Blake watched in shock and fascination as the strength of this man put several cracks in the window with just his hands alone.

One last punch and he went through the window before kneeling and standing back up.

The Joker ran to the opposite side of the gate as it activated, separating both him and his archnemesis.

"Welcome to the madhouse, Batman! I set a trap, and you sprang it gloriously!" he yelled as he spread his arms apart.

Blake watched as the inmates from the prison began to emerge from the sides of the room. Finally knowing what was going to happen, she turned to Gordon.

"I need you to uncuff me," she said.

"What for?" he gave her a suspicious look.

"He needs help."

"Batman can take care of it by himself," Gordon responded.

Blake cried out in frustration before grabbing her sword, slicing the links that bound her hands together and leapt through the broken window, rolling forward and standing beside the black-clad crusader.

"Hey, wait a minute!" Gordon yelled.

"Now let's get this party started," he said darkly.

Before Blake could even react, Batman threw himself towards one of the inmates, landing several audible punches before knocking him out and moving onto the next one. Another inmate caught sight of her and began throwing his own punches at her, which she quickly dodged.

"Ladies and maniacs, I apologize for this interruption to your regular entertainment. Up until a few seconds ago, I was going to kill everyone in the room and then watch cartoons. But then... well you know how I do love a captive audience," the Clown spoke through the mic in front of them.

She raised her blade to slice at the man, but she felt something hard hit her hand, knocking the sword out of her hands. The Faunus clutched the sore hand in pain as Batman finished off the last inmate, who was foolish enough to attack him, but he caught the fist and sent his knee into the unfortunate prisoner, knocking him out cold. She looked to the ground to see a bat-shaped object lying next to the man, the same projectile that struck her hand.

"Hey, I had it under control!" she said.

"No killing," he growled as he picked up the sword and tossed it to her, "Try that again and I will deal with you the same way I dealt with them."

Blake nodded reluctantly and sheathed her sword over her back.

"I'm just warming the both of ya up, Bats and Cat Junior!" Joker said, another group of inmates emerged from the cells between the two, "Fresh from Blackgate Correctional Facility, with a combined sentence of 752 years. Ding, ding, ding, ding, ding, it's round two!"

Blake raised her fists at level to her face in a boxing stance. She was quite adequate in close-quarters combat, but not enough to fight in a crowd of people, she and her team left that to Yang. She dodged a punch from one of the prisoners before jumping up and kicking him in the face, causing him to stumble back.

She blocked a jab from one of the others with her arm and landed a hard strike against his neck, immediately knocking him out. Blake used her Semblance and dodged another strike, quickly reappearing before the attacker and landing a hard strike against his neck, sending him onto the ground.

"What the hell?!" one of the inmates yelled as he witnessed her using some otherworldly power before attacking her as well.

"Sorry Bats, gotta run! I've got places to go, people to slay!"

The Faunus dodged under a left hook before sending a kick into the man's groin, forcing him to double over in pain. She then grabbed him by the shoulders and sent her knee crashing hard against his skull, breaking his nose and knocking him out as well. Blake turned to see Batman block two strikes before sending a fist into the man's abdomen and performed a front flip with his leg sticking out, causing the back of the black boot to make contact with the back of the inmate's head, sending into the ground with a cringe-worthy crack. Batman finished off the last two with a straight palm strike to the head with one, and the other with a high kick to the face, resulting in a high probability of a major concussion.

"The system's jammed! We're stuck in here, Joker's in full control of the security gates!" Gordon yelled.

Blake took notice that they were trapped by the gates that were on both sides of the room, until she noticed a rather large ventilation grate. She unsheathed her sword and sliced the vent apart before kicking the remains away, allowing for someone of surprisingly large size to go through should they crouch. Blake crawled inside only to find a dead-end and a green trophy-like object in the shape of a question mark. She made her way out of the vent with the object in hand.

Batman look at the object and took it from her hands, he then crushed the green object and tossed it aside.

"Nigma," she heard him growl, he then turned to face Gordon.

"I'll find a way out. Gordon, try and contact the Warden. Let him know what's happened, I'll be back."

"Don't make promises you can't keep, Bats. I'm in control of the Asylum. You're not going anywhere I don't want you to. Understand?" the Joker responded menacingly.

"If you think I'll let you run-"

"Blah, blah, blah! Always with the hero speak. Ooh, I'm getting bored of watching you. Why don't you just come find me," he whispered as the gate at the front deactivated.

"You know it's a trap, right?" Blake asked, following behind him.

"Of course it is," he answered, turning to look at the girl who walked closely beside him, "You're coming with me?"

"I don't know where I am, but I'm certainly not letting someone like that guy control this of all places," she replied, making note of the fact that they were in a place filled with mentally-ill people.

"If you're going to fight alongside me, you'll have to stay close if you want to survive," he said, then pointing an accusing finger in her direction.

"And no killing. Do you understand?" Batman demanded.

"Got it," she muttered, motioning to the sword that was still in it's sheathe.

"Good."

The two people dressed in black made their way passed the tunnel, furthering their descent into the depths of Arkham Asylum.
