AN: Thanks so much for all the positive feedback guys! I know I've said this a lot, but I really wasn't expecting such a positive response.

I'm so sorry for the massive delay. I could give any number of excuses, but I think everyone has waited long enough already.

Anyways, it's time to get into the action for real!

So, without further ado, Let's get it started!

Disclaimer: I do not in any way, shape or form, own My Hero Academia or Batman: Arkham Asylum

After making sure everyone was settled in, Anonymous gave another snap of his fingers and turned to face the screen. The lights dimmed down and the previous image on the screen faded into black, the animation resembling a swarm of bats.

It was a dark and stormy night, rain pouring from the heavens while the moon was barely visible behind a thick veil of clouds. A group of low-level clouds passed over the sky, there was a crack of thunder as they revealed a spotlight shining into the sky. Right in the middle of the beam, was a symbol in the shape of a stylized bat.

"Hey look! There's that symbol again!" Sero said, pointing at the screen.

"Must be Batman's hero symbol." Tsuyu guessed. She turned to look at Anon. "But why is it being shined into the sky? Is that significant?"

"Yep, for two reasons." The entity replied. "Number one, without any way to contact Batman directly, the Gotham City Police shine his symbol up into the clouds to let him know whenever he's needed. Number two, it's a homage to Batman's first appearance. After catching an infamous crime lord that had been avoiding the cops for ages, Batman strung him up on a spotlight with his jacket sleeves ripped up, making him resemble a bat."

"Cool!" Mina grinned. But then her face turned ponderous for a moment before pouting. "Man, I really need to come up with my own hero symbol."

The clouds finished passing by and the symbol vanished with them. The view then started to drop downward and passed by an old Gothic style building.

-All units, please proceed to Gotham City Hall. - a woman's voice said over a broadcast speaker, while more buildings started to appear in the background. The view finally reached ground level when she spoke again, this time over a police radio. -The Joker has been apprehended. Batman is now en route to Arkham Island. -

Two police cars raced through the street, sirens blaring as they made their way to Gotham City Hall. Just as an Ambulance came down the street in pursuit, something else came roaring from the opposite direction.

It drifted around a tight corner, revealing itself to be a jet-black bat-themed car. With a long nose, slim headlights, exposed engine parts, fins on the back wheels and roof, and vented rear wheel arches. When it finished turning, a jet booster built into the back roared into life, sending the car rocketing down the road and narrowly missing another police car.

"…"

"…"

"…"

"THAT IS AN AWESOME CAR!" Most of the boys, along with Ochako and Mina, cried in awe.

Anon grinned at their excitement. "That, ladies and gentlemen, is the Batmobile! Batman's main mode of transportation and easily one on the most famous vehicles in the multiverse!"

One boy, however, wasn't so enthusiastic. "What does he think he's doing?! Driving in such a manner, he's liable to hit someone!" Iida cried out. His arm was a blur with how fast it was chopping.

"Dude chill." Sero said, giving the class rep a mildly annoyed look. "He probably just prioritises getting this 'Joker' guy behind bars. You ask me, that sounds more important than obeying the speed limit."

Iida looked ready to retort, but upon seeing several of his classmates agree with Sero's statement, he huffed and sat down in reluctant acceptance.

The car continued to race through the streets at high-speed before eventually leaving the city limits. It soon found itself racing down a dark road that doubled as a natural bridge, Leading to an island just off the coast of Gotham city.

As it drove by, its headlights briefly lit up a signpost on the side of the road. The top signread 'Arkham' and pointed straight ahead, while another sign just below it said 'Caution: Hitchhikers may be escaping patients.'

Tokoyami raised an eyebrow. "That's odd." He mumbled to himself.

Jiro caught his comment thanks to her good hearing and turned to face him. "Huh? What is?"

"The sign stated that any hitchhikers could be an escapee." Tokoyami explained. "Now normally, I'd consider that nothing out of the ordinary. I'd even consider it logical for cautions sake."

The bird-headed teen narrowed his eyes as he got to his point. "But it's the word they used: patient. That got my attention. If this 'Arkham Island' is some kind of prison, then the proper term would be prisoner or convict. So why say patient?" he asked rhetorically, letting it sink in for a moment.

As a car continued to race down the road, the view changed to show its interior. It was too dark to see anything clearly, but two figures could be made out in the shadows.

The first was the one behind the wheel. The shadows inside the Batmobile prevented anything from being seen besides his silhouette, but a few discernible features included a pair of tall pointy ears and a deep scowl. There was a brief break in the tree's allowing the moonlight to shine into the car, revealing a bat symbol on the figure's chest.

"Oh, that's gotta be Batman!" Izuku cried, leaning forward with his notebook in hand and trying to get a better look at the shadowed hero.

"Oh man. Not even a proper glimpse yet and I can already tell he's a badass!" Kirishima grinned.

Right beside him was a second figure, who was wearing handcuffs and hunched over in his seat, muttering to himself. No distinguishing features except for a purple suit jacket with a yellow flower on the lapel.

"Stand back fool, I've got a bomb! Huh? Oh, right. Eheeheeheehee!" He giggled, another flash of moonlight revealing a wide grin full of teeth.

Toru leaned back a little, slightly creeped-out. "Okaaaay. Well, one things for certain. Whoever this Joker guy is, he sure is a creep."

The view changed again. Now it showed the base of a stone gateway, each side marked by a haunting stone statue. As the Batmobile raced through the gateway and out of sight, the view panned up to reveal the name 'Arkham Asylum' stretched across the top. Panning even further revealed the car's destination.

A series of tall, dark, and imposing buildings, all heavily influenced by gothic architecture.

Once the full name on the plaque was visible, Tokoyami's eyes widened.

"Ah! That what they meant by patient! This place isn't a prison, it's an…"

"Asylum." Shoto said, finishing his classmate's sentence. "In other words, it's a madhouse." His words sent a chill down everyone's collective spine.

The screen went black, and Anonymous stood from his seat.

"So, is everyone interested in seeing more?"

His response was a cacophony of cheers and whooping.

"Hell yeah we wanna see more!"

The scene reopened, just as a high-tech security door opened and revealed the two figures from before, highlighted the Batmobiles headlights and revealed in all their glory.

The first figure was tall and muscular, wearing a grey and black suit with a large bat emblem on his chest. He had a large billowing black cape behind him that was attached to an equally black cowl covering all but his mouth, chin and eyes, topped with a pair of pointed bat-like ears. He also had a yellow utility belt strapped around his waist and thick gauntlets, with a trio of spikes emerging from the backs.

Many of the class were in awe, especially Tokoyami and Izuku. The tall, imposing figure of the Dark Knight gave off an air that inspired both terror and strength. And yet, he also gave off a presence that instilled peace and safety, just like a true hero.

The man next to him was handcuffed behind his back, on his knees and was almost the exact opposite of the other man. He was fairly skinny and wore a pinstriped purple suit with a wilted yellow flower on the lapel and with black pointy shoes.

Batman reached down and grabbed the clown by his cuffs, yanking him to his feet and shoving him forward. "Move" He ordered in a voice as intimidating as his appearance.

The two of them marched down the hallway towards a small gathering of people. Three of them were security guards, dressed in armored vests and combat, while carrying assault rifles in their arms. Two of them were wearing helmets while the third (who stood just in front of his colleagues) was bare, revealing an ugly scar running down the side of his face and through his left eye.

The last person was a short, rather aged looking man with grey hair and a bald top, wearing a dark blue suit with a red tie, horn rimmed glasses and carried a cane topped with what looked like a gemstone with stylized large "A" inside. On right side of his suit, he wore a red rose. This was Quincy Sharp, the warden of Arkham Asylum.

Warden Sharp maintained a small but firm scowl, leaning on his cane as he watched Batman escort the Joker towards them. As soon as they were only a few feet away, the mad clown let out a demented giggle.

"Hey, Sharpie!" The Joker greeted. "Love what you've done with the place." As he finally came into the light, The class got a firsthand look at the twisted clown's face. From his bleach white skin, to his poisonous green hair and his ruby red lips that had nothing to do with make-up. Completing the look was a sick grin stretched across his pale face.

Ochako shivered audibly. "Oh yikes. And here I thought that Hand-guy at the USJ was creepy."

"Creepy nothing…" Kaminari said, noticeably freaked out. "Guy looks like one of those psycho clowns in horror movies!"

AI refrained from saying anything; the class would soon see for themselves just how sick and twisted the Joker could be.

"That's WARDEN Sharp to you." Warden Sharp asserted as he adjusted his tie, before calling his head guard, the man with a scar across his blinded left eye. "Boles!"

As Frank Boles stepped forward, Joker was quick to greet him as well. "Yo, Frank-ay! How's the wife and kids? Ya miss me?"

Boles grabbed Joker by the collar and shouted in his face; "Shut it, clown! A lot of people here really wanna talk to you." With his piece said, Boles led Joker over to a nearby restraining dolly, manned by the other two guards in attendance.

"Really, I don't mind walking" Joker complained as he was loaded onto the stretcher and locked in. "Not so tight boys, you'll crease the suit."

"Get that filthy degenerate out of here!" The Warden ordered sharply. (Heh~)

Batman however frowned, "Warden, something's not right. I'm going with him." Without waiting to hear Warden Sharps reply, Batman strode forward and followed the guards as they dragged the Joker away through the doorway. Above said doorway was a sign that read "ARKHAM ASYLUM INTENSIVE TREATMENT".

Tsuyu tilted her head. "Ribbit? Wonder what's got him so spooked. He's caught the villain and brought him in, that should be the end of it right?" She asked, confused by Batman's unease.

"Maybe Batman can see something that the rest of us can't." Shoji spoke up, drawing his classmates' attention. "Anonymous said that Batman is a master detective along with a hero, right? If that is so, then perhaps he's picked up on something we can't see that has made him suspicious."

The class could see the logic in that but couldn't quite tell what that 'something' was.

After passing through the door himself, Batman turned to face a guard on his right.

"Is Commissioner Gordon here yet?" He asked.

The guard, William north, replied promptly. "Yes sir! He's ah-waiting for you over in Patient Handover."

The group stopped at the end of the walkway before they platform lowered down to a lower level. There was a small chime and a female voice rang out over the intercom. "New patient in the Intensive Treatment lobby. All none-essential staff are to vacate the area."

The group continued down to the intensive care unit and toward a large chamber that happened to be a scanner and metal detector, to detect any hidden items. Joker lets about another laugh. "Ahh, it's always nice to return to my sweet little Ha-Ha~ Hacienda!" He laughed.

Momo frowned. "What's the matter with him? Is all of this nothing but a joke to him?"

"Probably why he's called 'The Joker'." Shoji replied.

Once inside the door shut with a hiss behind them before they heard a voice call over the speaker, "Tunnels full. Start the scan."

The machine started to hum and scan over all of them while Joker said, "You know, I prefer a good ol' cavity search. Much more personal."

However, the lights of the scanner flashed red and a guard spoke out, "Got a red light! Multiple prohibited items."

"I want Joker searched again!" The first voice ordered.

"Ah, it's not the patient, it's err..." The guard stammered. Joker who'd turned to look at Batman, seemed to realize the same thing as well. "Ooh, whatcha sneak in with you, bats?" He asked with a grin and leaned forward. "Come on, tell me, tell me! Batarangs? Batclaws? Oooh, Bat-snacks?"

"What, what and what?" Ochako asked, tilting her head.

"He's probably talking about support items." Izuku theorized. He was hunched over with a hand on his chin. "The name 'Batarangs' speaks for itself: boomerangs in the shape of bats. 'Batclaws' on the other hand could mean anything. A grappling hook, a pairofclawedgauntletsatrackingdevicemaybeevena…"

"MIDORIYA!"

Izuku jumped when the entire class shouted his name, realizing he'd been muttering again. His classmates gave him amused or annoyed looks as he apologized, more than used to his habit by now.

"Scan is green on Joker." The guard confirmed for them.

"Open the gate! Get him out of there!" The first voice ordered to the guard.

The doors ahead of them opened, allowing the group to move out of the tunnel. Waiting for them just outside was another uniformed guard. This one was African American, with short-cut hair and a firm expression, keeping his weapon trained on Jokers face. This was whom the first voice belonged to, Officer Aaron Cash.

"I want weapons on him at all times" Cash said as the escort wheeled Joker past him, "Do not let him out of your sight."

"There will be time for you later, Cash." Joker said to him as they moved away, "Speaking of time; tick-tock, tick-tock. Oooh, is that a crocodile I hear?" Cash glared at the criminal clown, but Joker just laughed at his own joke.

Momo frowned in confusion "Why in the world would Joker taunt that guard with a crocodile?"

"Just taking a guess here…" Sero said. "But it might have something to with that hook." He pointed one of his hand at Cash, or more specifically, the two-pronged hook that took the place of his left hand.

Kaminari scratched his head and raised an eyebrow. "So, what? He lost it to a crocodile and has a fear of them now?" His question was aimed at their host, who remained silent for a moment before saying.

"Something like that..."

"Oh my god!" As they moved away from Cash towards a door on the right side of the room, a small voice attracted both Batman's and Joker's attention. Standing behind two guards positioned on the right was a female doctor, who was clutching a clipboard to her chest while staring in petrified fear at the clown.

Joker noticed her fear immediately and his sadistic grin widened. "What's up, doc! Pencil me in for tomorrow at 4. We've got a lot of catching up to do-hoohoohoohoo~!." He called out, followed by another demented laugh.

They group walked down a new hallway with several tv monitors before they came to life, showing Warden Sharp on screen. They started to play a recording, speaking to the 'new' patients into the asylum. Joker seemed to be amused by this. "Ooh, it's my favorite show! 'I'm warden idiot', 'you'll never escape'"

Batman said nothing as they pass a section where half the hallway was blocked by bars. He didn't take much notice until he heard someone on the other side speak, "Hey, it's Joker."

"Joker! Joker!" another man chants.

"Hey Joker!"

"Hear about Blackgate boss?"

"Yo, got your suit boss!"

Batman glanced over to see a group of men being led down the hallway in the other direction. However, they were dressed in either gray or brown prison garbs. They were marched with their hands on their heads as the guard kept their weapons on them, all telling the men to keep quiet.

"Huh, are those thugs?" Sato asked, scratching his head in confusion. "I thought this was a mental asylum. Why are there prisoners here?"

"It's definitely strange. And by the way they're cheering, they must work for the Joker." Momo muttered softly, thinking it could be trouble if Joker's group was in the same place as the Joker himself.

Joker sighed, barely glancing towards his men. "I'm telling you, the state of the wiring in these federal facilities is shocking. My boys over there could've been hurt in that 'unfortunate' fire."

Batman frowned. A few days ago the Blackgate Penitentiary, where most petty thugs and clinically sane criminals were sent to, had suffered from a massive fire that left the building unsuitable for housing prisoners. As a result, a majority of the Joker's crew had been moved to Arkham while repairs were made.

"How convenient." Shoto muttered, narrowing his eyes in suspicion. Izuku, Iida and the other smart members of the class nodded in agreement; that sounded like far too much of a coincidence to them.

They stopped by a small group of guards and a doctor holding a clipboard. The doctor stepped forward "Just have to check your patient, officer Boles."

Boles gave an ugly scowl and said impatiently "Alright, just be quick about it!"

"Only following procedure." The doctor stated, stepping forward and checking The Joker out without touching him. "Patient seems to be in satisfactory condition. Looks like he suffered minor lacerations, probably in the last two hours. There seem to be..." the doctor paused, getting a little closer to Joker's face.

"Boo!" The Joker suddenly shouted, causing the doctor to jump back as did the guard who raised their weapons.

The students also jumped, some of the girls letting out yelps of fright while some of them (like Bakugou and Kirishima) readied their quirks in reflex.

The Joker just laughed like a lunatic, even though no less than five automated weapons were pointed right at him. "Need to take my temperature?" The clown then abruptly asked the doctor "I'd be happy to drop my pants."

Mineta and Kaminari turned green and had to resist the urge to puke.

"Oh, gross!" Mina cringed, turning a shade of grey. "I SO did not need that image in my head!"

The doctor however had enough. "He's all yours. Get him out of here."

One guard reported over his radio. "He's good. Open the door."

The thick doors opened up, allowing the small convoy to pass through with their deadly cargo. Through the door, was over half a dozen guards standing before an open elevator shaft where the cabin moving, showing the elevator was moving up. As they approached the elevator however, a chime came over the loudspeakers followed shortly by an announcement. "Attention in intensive treatment: Category 9 patient in transit. Pacification systems active. Shoot-to-kill permission granted."

One of the guards, a rotund uniformed man named Louie Green, held out his hand to stop their approach. "You heard the lady; we've got another psycho on the way."

Despite the guards bringing their weapons to arms and even Batman tensing in preparation, Joker just found the whole thing amusing. "Can you smell the excitement in the air? No? Must've been one of the guards. Croc, old boy! Is that you?"

The clown had turned his attention to the lifting elevator, which had sparks flying out of its sides while moving quite slowly, straining to lift a very heavy load. Everyone could barely see a hunched figure inside the elevator as it finally stopped at the top floor. "Get ready," one guard said as the gate slid open, "And keep your weapons trained on him at all times."

"He looks angry" one guard muttered softly

Something big climbed out of the elevator, shaking the ground with every step it took. Once outside the creature stood straight up, towering over all of them in size and height. His body was covered in mostly green scales, with an almost flat face that sported yellow reptilian eyes and a mouth full of wicked, oversized teeth. Wearing only a pair of prison pants, chains around his wrists and a collar around his neck, it hissed when a spotlight was shined on him.

The class stared in silence, some in awe and some in horror. Sure, they'd seen all sorts of villains with horrific features in the past, many of which were during the attack on the USJ. But something about this monster set them on edge.

This…creature seemed to give off an air of pure, savage rage, which could be felt even through the screen. It felt more like they were staring at a bloodthirsty beast than a villain.

It was almost like being faced with the Nomu again.

The monster of a man suddenly sniffed the air, then turned to lock eyes with Batman., "What's it doing?" another guard asked. 'Croc' took a few steps forward and spoke, in a growling gravelly voice.

"̯̖"̶I͜'v҉e͢ got ́yo҉ųr ̕s͞c̀e̡ņt, ̶B̛at͡m̕an̢!͜ ̵I͜ will͡ hùnt ͠yơu ͞do̕wn.͢"̵

"Power it up! Get that animal under control!" One guard ordered.

The large collar around Croc's neck hummed with power before it started to spark, shocking the beast. He growled in anger and pain before it finally stopped.

"A ͏t̴o̸y col̨làr͏ w͠on̴'t ̶st͘o̵p ḿe from̢ ki͡ll̡i̛ng y͏o̶u̡,͘ ̀B͞atma̵n.͘ ͟I'll r͜ip̴ yo͢u̶ apar̀t́. E͡at̵ your b͟o̴n̨es.̢"̛ ͘ ͖͙Croc snarled as he started to stomp off with a few guard following him, Batman keeping his eyes on the beast even after he vanished through the other doorway. A few seconds later, the silence was broken by Joker. "That reminds me. I really need to get me some new shoes."

"…who…or what…was that?" Ojiro asked, his voice wavering slightly from fear.

"That, was Waylon Jones." Anonymous explained to him. "Aka, Killer Croc. Born with an exceedingly rare condition that gives him a reptilian appearance, that only grew worse with age. After years of constant bullying and being labelled as a freak, he eventually snapped and decided to become the very animal that society believed him to be. He's been charged with multiple acts of assault, murder… and cannibalism."

"C-C-Cannibalism?" Midoriya repeated quietly, almost dreading the answer.

Anon was silent for a moment before responding. "When the Gotham City Police discovered one of Killer Croc's old lairs, along with the remains of several of his victims, they never managed to recover all the pieces of their bodies. This was brought up during one of Croc's interrogations, and he claimed that they should've looked in the sewers. When asked if that was where he hid them, this was his reply…"

Anon held up an old recorder and pressed the play button. "Ąf̢ter ̵a wh͏i͜le.͠ ̕Ųsual҉l̛y͢ ͡ta̵k̷es ͟abou͏t, ̕8 ͡h͏ours̡.̡ ̵H҉eh̛, R̢A̶ḨA͞HA҉HAH̀A̧H͜AH͠A̶HAHAH̢AHA!"

The students quickly picked up on the meaning of Croc's statement. Several of them somehow paled and turned green at the same time, before they started vomiting into conveniently placed buckets.

One of the guards spoke up. "Okay, move up."

Batman followed along as Joker was wheeled into the elevator. Once inside, the gate shut behind them and the guard stated, "Hold tight." The elevator shook slightly, and they started to descend to the lower levels.

"Wee! Great night for a party!"Joker exclaimed after a few seconds.

"Not where you're going." Batman stated simply.

"Ah, the night is young Bats" Joker retorted airily. "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 crew to be moved here?" He asked with a seemingly innocent tone, but the sick little giggle that followed betrayed any innocence.

The Dark Knight didn't say a word. He was already on edge when he'd seen the Joker's crew here in the asylum. But now hearing the clown all but confessing that he'd planned the fire only caused his suspicions to rise.

"I thought I told you to stay quiet!" Boles snapped at Joker.

Joker glanced at the guard for a moment. "Oh, Frankie. You know really should learn to keep that fat mouth of yours shut. It'll get you into trouble." This last part was enunciated with a sinister growl, but the guard didn't seem bothered by the threat.

"Tell me something," Batman interjected, either to get Joker's attention off Boles or because he really wanted information. "You've never let me catch you this easily. What are you really after?"

"Oh, nothing much." Joker replied easily, acting like he was inspecting his fingernails even though he wore a glove. "Hundreds dying in pain and fear. Their miserable lives brought to a horrifying conclusion. All thanks to you and a book of matches. Was that the answer you wanted?"

"What a sick individual." Iida muttered with a frown.

"Oui, mon ami." Aoyama gave a concurring nod. "Absolutely insensé."

Then suddenly the television beside them started up, playing another recording of the warden. "All patients should avoid contact with prisoners from Blackgate Prison Facility. Their presence in our institution is…"

But then suddenly the speaker waned, and the lights flickered as if about to go out. Joker was laughing the whole time as it went pitch black. The guard were panicking, "What's he doing?"

"Stay where you are!"

"Get a flashlight!" Boles ordered, "Get a light on him!"

Joker's laughter was suddenly cut off and replaced by a choking gurgle, right before the lights came back on and the tv recording started again. Joker was still strapped to the gurney, but now Batman was holding the man by his throat so that he couldn't escape.

Joker roughly choked out. "What? Don't you trust me?" Batman didn't answer and slammed the Joker's head to the back of his harness.

The class breathed a consecutive sigh of relief.

Tsuyu was the first to speak. "Thank god. I thought he was gonna get loose for a moment there, ribbit." Her face was as blank as ever, but the slight hitch in her breathing betrayed her nervousness.

"That makes two of us." Izuku replied as he wiped his forehead of sweat.

The elevator shook as it stopped at their destination. "Our guest has arrived," said a guard waiting outside the elevator gate. It opens up and the group walked or rolled out with several guard standing at the sides all with their guns up and aiming at Joker. A chime was heard again as the announcement said, "Intensive Treatment lower floors are now in level Red Alpha."

"So you're back," one guard stated, "You killed three of my crew when you busted out of here."

"Only three?" Joker asked with a laugh. "I'll be sure to try harder next time. What say we aim for a hundred?"

They finally made it to patient hangover. A man with graying hair and a mustache was finishing up some paperwork on a clipboard. He turned around when they turned up, allowing everyone to see he was dressed in a blue vest with his badge strapped to his belt and a pistol in a hostler strapped to his chest. Batman turned and greeted the man with a small smile, "Long night Jim?"

The man gave a light-natured scoff, walking up to the Dark Knight and shaking the man's hand all while saying, "Joker invades city Hall and holds the mayor hostage, leaving it to me to juggle SWAT teams, the media, and you. Yeah, it's been a helluva night."

"Hopefully the last one we'll ever have with him." Batman stated, nodding his head to Joker.

What he didn't know was that someone was watching their every move through one the security cameras; someone who wasn't a guard. The female figure leaned back, her mismatched red and purple boots bouncing off each other as she giggled madly. "Yeah right."

"Who's that?!" Mineta and Kaminari cried in unison. Their excited outburst causing most of their classmates to give them exasperated or disgusted looks.

"I wouldn't get too excited if I were you." Anonymous called out before they could get too excited. "As tempting as it might be, touching that particular honey pot would violate one of the integral rules of the bro-code."

The two perverts were about to inquire as to his meaning, but the screen drew away their attention.

But his train of thought was broken when he noticed Joker was taking out of the harness and was being moved on foot with his hands cuffed in front of him. Batman and commissioner Gordon headed towards them before one guard held his hand out to them. "Hold it, there! Sorry, Batman; Arkham staff only."

Commissioner Gordon frowned "I assure you, if anyone's qualified, it's…"

The guard however cut him off, "Listen, I appreciate the assistance, but he'll unsettle the more violent inmates."

Joker chuckled jerking his head to Batman. "I think he's talking about you, Bats!" He laughed as the laser gate shut off and he was led through. As he was led away he started off "Don't be a stranger! You're always welcome here! Gotta say, it's good to be back!"

Batman watched as the Joker gave another laugh, an uneasy feeling settling in. Jim noticed this, "You okay?"

"He surrendered almost without a fight. I don't like it" Batman said moving inside the booth to watch the progress through the window. Gordon followed him.

"At least he's back where he belongs." Gordon said with a nod.

Batman said nothing. He had a feeling that something was very wrong and as anyone who knew him could attest, his felling were usually right.

Inside the next room Joker took a glance back to see batman watching him before he grunts and fell to his knees. "Get up," the guard escorting him ordered. He didn't see Joker's smirk as the guard reached to lift him up. "Now!" the guard ordered again.

Joker acted at once, headbutting the guard before he the clown quickly got behind the guard and threw his cuffed hands over his neck, strangling the struggling guard.

"-tch- Of course, something has to go fucking wrong." Bakugou snarled.

"Joker's loose! Alert the warden!" Batman demanded.

"Hurry, we're losing him, Doc!" Joker screamed to the doctor, who was trying to undo the cuffs to save the guard.

Batman punched the bullet proof glass window, cracking it heavily but not fully breaking it.

Just as the orderly managed to unlock one of the cuffs, Joker spread his arms apart, shoved the struggling guard to the floor and kicked the doctor away from him. Joker then rushed over to the guard, leaned in close to his (hopefully) unconscious face and whispered. "The chokes on you!"

With that said, the deranged man began dancing around while giggling like the lunatic he was before pointing to the opposite gate.

"Ta-da! Honey, I'm home~!" he sang, looking directly at one of the cameras. On the other side, the mysterious observer swiped a keycard as she sang back. "Come on in~"

Just as the security door shut off, Joker looked behind him just in time to see Batman launch himself through the shattered glass, landing on the ground behind him as the mad clown ran forward and dove through the door. Joker laughed as he stood up and posed while the security door reactivated, "Welcome to the madhouse, Batman! I set a trap, and you sprang it gloriously!"

Batman just narrowed his eyes at the Joker. He then heard the doors to the cells around him open up and the prisoners walked out of them.

"About fucking time dammit!" Katsuki yelled with a savage grin. "Let's see if this so-called 'Dark Knight' is all you cracked him up to be Green Brows!"

Anonymous just leaned back in his chair and put his hands behind his head, confidence practically oozing off of him. "Ask, and you shall receive."

Joker laughed as he ran into a booth on the other side of the room and spoke over the loudspeaker. "Let's get this party started."

The four released goons charged at him, cheered on by their still imprisoned gangmates. Batman countered the first one's sloppy punch before he returned one of his own then landed another, knocking the thug away in a daze. He waited until the next one was close enough before swinging his arm to knock the oncoming punch aside before he turned, lowered himself and swiped the man's feet from underneath him, knocking him out when his head hit the floor.

Some of the class winced at the crack when the thug's head stuck the metal floor.

"Ooh yikes." Mumbled Sato, rubbing the back of his head as if he could feel the pain himself. "That's gonna hurt once he wakes up."

Kirishima, on the other hand, was sporting a wide grin at as he watched the Dark Knight at work. 'Oh man, that was awesome! Something tells me we're to see something totally manly!'

Batman was already up again to block another punch with his arm before whirled round and flung his cape in the third thug's face, leaving him open to a swift beatdown that sent him into unconsciousness. As the fourth thug lunged at him, Batman leapt up and vaulted over the goon, barely giving him a chance to stagger before landing a brutal kick to the thug's back. The goon screamed as he was sent flying across the room, only to slam headfirst into the wall and join his fallen friends.

Batman turned to glare at the only remaining thug, who had only just shaken off his dizziness and realised his predicament. Shaking in fear he made a break for the security gate, begging the Joker to let him through. Thinking up an idea in a flash, Batman waited until the goon was close enough to the gate before reaching into his belt, pulling out an object and tossing it. All in one fluid motion.

The object unfolded in midair into a mixture of a shuriken and a boomerang, shaped like a bat. The 'Batarang' whirled through the air and nailed the thug in the back of the head, sending him head-first into the gate and shocking him into unconsciousness.

The class were in awe. Sure, they'd seen one man take on several opponents at once before, that being Eraserhead at the USJ. But the way Batman had seamlessly flowed from target to target, taking out each one with quick precision. That required skill that took years to perfect.

Joker just laughed over the loudspeaker, as if amused by watching his thugs get their assess kicked. "I'm just warming you up Bats. Fresh from Blackgate Correctional Facility, with a combined sentence of 752 years! Ding, ding, ding, ding, ding! It's Round 2!"

Five more inmates were let out of their cells and they ran right at the Dark Knight. Batman waited till they were close enough before he went on the attack, knocking one inmate down with a haymaker before he caught another one's punch, smacked his ears to discombobulate him then laid him out with a jab.

While he was busy fighting, Joker spoke through the loudspeaker. "Sorry Bats, but I gotta run. I've got places to go and people to slay~."

The hero gritted his teeth as Joker made his getaway. Batman dove at the last inmate, wrestled into a roll for a quick second before he twists the leg, causing the man to cry out in pain. He was out cold soon after that. With the inmates all down and out, Batman rose to his feet and looked at the booth Joker was in before, only to find it now empty and the security door was still up on either side of the room.

Gordon appeared on the one of the screens, his voice being broadcast over the speakers. "The system's jammed. We're stuck in here. Joker's got full control of the security gates

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

But then the screen changed to Joker in down a hallway before he turned to the camera. "Don't make promises you can't keep, Bats! I'm in control of the asylum. You aren't going anywhere I don't want you to. Understand?"

Batman glared at the screen and growled, "If you think I'll let you run…"

But Joker cut him off. "Blah, blah, blah! Always with the hero speak! I'm getting bored watching you. Why don't you just come and find me..?" Right when Joker was finished, the security gate that he'd escaped through earlier suddenly powered down, freeing the way to follow him.

"You know it's a trap." Gordon said, despite knowing Batman was clearly aware of that fact.

"Of course it is" Batman confirmed. He then turned without another word, sprinting up the ramp and down the corridor, in hot pursuit of the Clown Prince of Crime.

AN: Well, there it is. Finally.

Hope you all enjoyed it, and I swear that the next chapter won't take so long to complete (certainly not half a year again).

Anyways, stay safe and stay smart out there everyone!

Until next time, Cheerio!
