Batman Begins: Enter Seto Kaiba

Disclaimer: I don't own Yu-Gi-Oh or Batman!

Arkham Asylum-Outside entrance

The 2 League members start running outside the entrance doors, and 1 of them begins hits the detonator. Instantly the walls of the Asylum are blown apart, resulting in a large hole, big enough for the escaped inmates to cause some havoc upon Domino.

Immediately, Mutou hears the explosion from below in the underground refinery rooms. Meanwhile, the escaped inmates found the broken walls and start running out into the open, with one of the 'SWAT' soldiers.

Kaiba Mansion-Main Entrance

Ra's al Ghul walks out of the burning Mansion's entrance doors, and motions a ninja to guard the doors.

"No one comes out, make sure. Including the boy..."

Continuously, he walks towards a stolen SWAT van and goes inside along with his "squad". Immediately, the vehicle leaves the fiery Mansion to destroy Domino.

Near Arkham Asylum-Mutou and Trudge, et al.

"Trudge, they're all gone? How many from maximum security?"

"Everyone of them. Serial killers, rapists..."

"Get Sheppard to raise the bridges. We don't want any getting off the island."

"Yeah, I'll raise the bridges... when I get every available unit out here to catch the homicidal maniacs that are running loose out there."

"Come on!"

Téa's apartment

She starts waking up from the sedative, and picks up the antidote vials nearby to give to Mutou.

Kaiba Mansion

Kaiba, still unconscious, is still pinned down by the burning wood above him. It seems like he may die here.

A ninja guards the doors, armed to make sure no one interferes. When all of a sudden...WHACK! The ninja goes down by Arthur, who was using the nine iron club in his hands.

"I hope you're not a member from the fire brigade. Come on, Mokuba!"

Immediately, Mokuba and Arthur start running through the flames to save their brother/friend from dying in the inferno. Rushing into the burning library, Arthur sees that his Master is unconscious beneath the flaming wood.

"Master Kaiba! Master Kaiba!"

He sees him start to open his eyes. Kaiba tries to push the wood above him and a freed Mokuba tries to help as well.

"What is the point of all those push-ups if you can't even lift a bloody log!"

He looks at Mokuba and Arthur. Getting his energy back. Instantly, he forces the weight of the "log" off his chest. Both Mokuba and Arthur grab and pick him up. They both start for the study room to get to the cave.

Mokuba is near the grand piano and presses the 3 burning piano keys. Quickly, the three enter the secret bookshelf doors and inside the dumbwaiter to descend below. Before a large mass of flames could consume them, Arthur quickly yanks the lever, dropping the elevator downward. The Mansion is quickly burning down to the ground, the Kaiba family's home is destroyed.

Batcave

They descend into the caves below them. When they reach the bottom, Seto has some depressing to say.

"What have I done, Arthur? Everything my family... my father built."

Arthur looks at Kaiba's bleeding torso, he's only human.

"I'm still your family, Seto." says Mokuba. Arthur turns and looks at his "sons".

"The Kaiba legacy is more than bricks and mortar, sirs."

"I wanted to save Domino. I failed."

"Why do we fall, sir? So that we can learn to pick ourselves up."

"You still haven't given up on me?"

"Never."

-Narrows

Trudge and several other units manage to recapture some of the freed inmates of Arkham Asylum.

"Down!"

One Narrows civilian criticized, "Harassment, I see harassment!"

Trudge, aims his gun and replies, "Well, maybe you'd like to see some excessive force?"

"Madman with a gun."

Meanwhile, other units are gathering every available unit to the Narrows. News reporters with cameramen show the current situation: "With residents furious at the unprecedented show of police strength to round up the inmates..."

Téa starts to run towards to Narrows to give Sergent Mutou the antidote.

"Whoa, lady... we're about to raise these bridges," states a police officer.

"Officer, I am a Domino City district attorney, so let me pass.

At the same time, more and more police units are going across the bridges.

"Just shut up!"

"Ushio, cool it!"

Groups of Narrows civilians are complaining while the police are ordering them to stand back. Téa starts towards Mutou, with a common cop guiding her to Mutou.

"Hey, Mutou. Somebody here to see you."

"What are you doing here?"

"Our mutual friend sent me with this."

She shows him the antidote needle.

"It counteracts Bakura's toxin. Hopefully, you won't need it."

"Not unless he's got some way of getting that crap into the air."

In the meantime a certain SWAT van drives into the Narrows, inside it is one of the remaining members of the League of Shadows.

"All right, last one across."

"Come on, people, they want this bridge up in no more than 3 minutes!"

Back to Téa and Mutou

"Better get you off the island before they raise the bridges. Patrolman!Go!"

The Kaiba Corp monorail stops to a complete halt for some reason. Below it's support structures, the League of Shadows are setting up the microwave emitter.

"Leon, a boy about 12 nearby the 'SWAT' van, asks one of the disguised League of Shadows, "I can't find my brother, Zigfried."

The ninja just pushes the kid away, while Téa was nearby.

"Hey! What the hell are you doing?"

Meanwhile the bridges of the Narrows are being raised.

Back to where Téa is, the "ninja" points his finger to her head, while Ra's al Ghul emerges from the doors.

"Gentlemen, it's time to spread the word, and the word is: panic."

Instantly, the cult leader activates the microwave emitter before him. The water pipes around them explode, releasing the toxins into the air. Toxins are flying everywhere nearby, where the cops and many others are, infecting them.

Kaiba Corp-Water Authority

One of the workers notice something drastic in the water mains under the Narrows.

"Jesus, the pressure, it's spiking. Right there."

The elder worker checks to see.

"That water main is right under the Narrows."

Narrows

The League of Shadows, now wearing gas masks to spare them the hallucinations from the toxins, are enjoying Domino suffer before their very eyes. Téa, now holding the little boy, is reassuring him that nothing bad will happen.

Dozens of people in the Narrows are coughing and hallucinating under the toxin's influence around them. Mutou had injected himself with the antidote to counteract the poison that's infecting everybody near him.

Meanwhile, Trudge, who's now drugged, sees 2 kids nearby and sees them as little demons, he's about to shoot them, until Mutou comes up from behind and knocks him out. Trying to save the 2 kids, he handcuffs his corrupt partner to some metal pipes.

Commissioner Sheppard, who's nearby the bridges outside the Narrows is calling on dispatch.

"This is Commissioner Sheppard, come one somebody talk to me. Come on!"

Batcave

Already wearing his body armor, Kaiba thrusts his bronze gaunlets over his wrists. Instantly, his utility belt is strapped onto his waist, like a whip. On a table nearby, dozens of batarangs are placed ontop. He takes and attaches the shurikens onto the magnetic attachments of the belt. Finally, he snaps on a grapple gun, and takes some mini mines as well.

Moments later, he flies down to where the Batmobile is. And in a flash, the gigantic tank, bursts its way out of the cave's waterfall with it's jumping ability.

Narrows

Dozens of people are going crazy, eating and biting cops and other civilians. On the other side of the Narrows, Mutou is contacting with Commissioner Loeb.

"Sheppard! This is Mutou."

"What the hell is going on in there?"

"We need reinforcements. TAC-teams, SWAT, riot cops!"

"Mutou, Mutou. All the city's riot police are on the island with you!"

"Well, they're quickly incapacitated."

Where Téa is, a dark rider on a black horse is coming towards her and the little boy.

"It's okay, it's okay. No one's gonna hurt you."

"Of course they are!"

"Bakura?"

"No. Scarecrow!"

In a crazed frenzy, the psychotic, former mental psychiatrist, is chasing away at his once fellow colleague.

Narrows-later

"Mutou... there's nobody left to send in."

As soon as he said those words, a monstrous sized vehicle jumps across the river and into the chaotic island.

"So am I on my own?"

Somehow, amazingly, the Batmobile arrives to where Mutou is. The car doors open, and the Batman jumps out.

"Batman, the Narrows is tearing itself to pieces."

"This is just the beginning. If they hit the whole city with the toxin, then there's nothing to stop Domino from tearing itself apart from mass panic."

"How are they gonna do that?"

"They'll be using the train. The monorail follows the water mains to the central hub beneath Kaiba Tower. If they get their machine into Kaiba Station, it'll cause a chain reaction that'll vaporize the entire city's water supply."

Now getting the idea, Mutou responds, "Covering Domino in this poison."

"I'm gonna stop him from loading that train, but I may need your help."

"What do you need?"

Taking out The Burst Stream's remote device, "Can you drive stick?"
