-Gotham City-

Wayne Manor

Bruce Wayne and Bruce Banner are relaxing the night away...until Alfred walks into Bruce Wayne's room, telling him that the Joker has attacked City Hall and is currently holding the Mayor hostage. As Bruce rushes towards the entrance to the Batcave, he stops by Bruce Banner's room.

"Bruce." He calls out to Bruce Banner.

"Yes, Mr. Wayne?" Bruce Banner has always been respectful, and always adresses him as Mr. Wayne. "What's going on?"

"It's the Joker. He's at City Hall, and he has the mayor as a hostage. Since Joker is so...cooperative with you around, why don't you come with?"

Bruce Banner was very apprehensive about going and fighting crime, but he wanted to contribute, so he nodded as he got off his bed and follows Bruce Wayne into the Batcave.

-The Batcave-

Bruce Wayne quickly rushes over to a cylindrical shaped container, which opened up to reveal his Batsuit. As Bruce Banner puts on some stretchy pants in case he's forced to transform, Bruce Wayne finishes putting on his suit. The two enter the Batmobile and exit the Batcave, speeding off towards City Hall.

-Gotham City Hall-

The Batmobile pulls over to the side of the road as the two heroes exit the vehicle to be greeted by several GCPD officers.

"Batman." One of the officers says in greeting.

"Joker?" Batman asks, receiving a nod from the same officer.

"Yeah. He's inside, got a gun to the Mayor's head. Says he'll shoot if he sees any of us even try to enter the building."

"Tell your men to stand down. We'll handle it from here." Batman says as he and Bruce Banner enter the building. The two walk down a long hall before entering the Mayor's office. Joker spins around, holding the Mayor in front of him while aiming a revolver at Batman, who simply scowled at Joker.

"Ooh! So tense, Bats! Has anyone ever told you that too much anger is bad for your brain?" Joker quips as he hides behind the Mayor.

Bruce rolls his eyes as Batman swiftly tosses a batarang, knocking the gun out of Joker's hand before leaping towards him and knocking him down with a painful right hook. As Joker laughs, Bruce runs outside to tell the GCPD officers that the Joker has been apprehended.

-Later-

Batman escorts a handcuffed Joker to the Batmobile while Bruce is put into a police cruiser as Batman speeds off towards Arkham Asylum, followed closely by the police car Bruce was riding in. The whole time he was driving, Batman had a sick feeling that Joker had something planned, since Joker surrendered almost without a fight...

"Stand back, fool! I got a bomb! Oh, wait...Hahahahaha!" Joker quipped.

-Arkham Asylum-

Batman parks the Batmobile at the front entrance of the main building complex as he drags Joker out of the passenger seat. Once the door opens, Batman forces the Joker to walk forward. Joker is then greeted by a balding man in a suit and carrying a cane as well as two armed guards one of which had a shaved head and a scarred eye.

"Hey, Sharpie! Love what you've done with the place." Joker remarks as he moves closer to the man.

"That's Warden Sharp to you." The balding man said. "Boles." He adds.

"Yo, Frank-ay. How's the wife and kids? You miss me?" Joker teases as Boles roughly grabs him by the collar of his suit.

"Shut it, clown! A lot of people here really want to talk to you." Frank says as he pulls Joker towards a restraining gurney.

"Really, I don't mind walking!" Joker argues as the guards strap him in. "Not so tight, boys. You'll crease the suit. Hahahahaha!"

"Get that filthy degenerate out of here." Sharp says with disgust as the guards start rolling the gurney away.

"Warden, something's not right. I'm going with him." Batman says, still feeling something was up.

-Intensive Treatment-

"Is Commisioner Gordon here?" Batman asks a nearby guard.

"Yes, sir. He's, err, waiting for you down at Patient Handover. He got here just before you and Dr. Banner did." The guard says in reply as Batman walks past him.

As the guards wheel him to a lift, Joker grins. "Sharpie loves his cameras. Hey, Sharpie! You getting my good side? Heck, they're all good, aren't they? Hehehehehe!"

"I want him securely locked away this time. Another escape, and I will lose support for my mayoral campaign." Sharp says to a guard.

"Don't worry, Warden. I have every available guard stationed here today, sir." The guard says in response.

"I hope it's enough, Officer North...for your sake." The Warden says in a not so threatening way.

"Look at all this new security! How's a guy supposed to break out of here?" Joker teasingly asks.

-Later-

Batman, Bruce, Joker, and several guards arrive at an elevator, being told that another 'psycho' is on the way.

"Can you smell the excitement in the air? No? Must've been one of the guards then. Croc old boy, is that you?" Joker asks as he tries to turn around to look at the elevator as a large humanoid with crocodilian features slowly exits the cramped elevator. A spotlight shines on its monstrous face as it picks up Batman and Bruce's scents and looks right at them.

"I've got your scent, Batman. You too, Bruce. I will hunt you both down." Killer Croc says in a growly voice as one of the guards activates the shock collar wrapped around Croc's neck, sending a painful shock through his body. "A toy collar won't stop me from killing the two of you, Batman. I'll rip both of you apart. Eat your bones!" He threateningly yells as he walks away.

"Oh!" Joker abruptly says, easing the tension. "That reminds me. I really need to get me some new shoes."

-Patient Handover-

Joker is wheeled into a reception area, where Commissioner Gordon is signing Joker over to a doctor.

"Long night, Jim?" Batman asks, receiving a chuckle from the veteran lawman as he shakes the Caped Crusader's hand.

"Joker invades City Hall and holds the Mayor hostage, leaving it to me to juggle SWAT teams, the media, and both you and Bruce. Yeah, it's been a hell of a night."

"Hopefully the last we'll ever have with him." Batman says as he and Jim follow Joker, who has been released from the gurney.

However, a guard motions Batman and Bruce to stop. "Hold it there! Sorry, Batman. Arkham staff only. The same applies to you, Dr. Banner."

"I assure you, if anyone's qualified, it's-" Gordon tries to say before being interrupted by the rude guard.

"Listen, I appreciate the assistance, but they'll unsettle the more violent inmates. Especially you, Dr. Banner."

Joker chuckles as he's escorted past the two. "I think he's talking about you, Banner. But don't be a stranger. You're always welcome here. I gotta say, it's good to be back. Hehehehehe!"

"You boys okay?" Gordon asks Batman and Bruce.

"He surrendered almost without a fight. I don't like it." Batman says cautiously.

"Well...at least he's back where he belongs." Gordon says smugly as Joker is escorted towards his cell, an electric barrier activating behind him to keep him from escaping. Halfway through the walk, Joker stumbles onto the floor. As the guard attempts to get him up on his feet, Joker hits him with his head, dazing him as Joker strangles him with his handcuffs.

"Joker's free! Alert the Warden!" Batman yells in distress.

"Hurry! We're losing him, doc!" Joker remarks as Batman tries to break through a window. Once he kills the guard, Joker simply kicks the doctor to the floor and leans down at the dead guard. "The choke's on you. Hehehahahaha! Honey, I'm home!"

Suddenly, the barrier in front of Joker deactivates, allowing him to escape right as Batman breaks the glass.

"Welcome to the madhouse, Batman! I set a trap, and you sprang it GLORIOUSLY! Now let's get this party started!"
