Mister J hadn't realized that there was a tracer inside of the bike he stole.
Jack glided above the streets below, chaotic with a war that must have started not long ago.
CItizens were in the streets, fighting off the Jokerz. Some were dressed in all black, to show that they were on Batman's side.
The buggy heads up display showed Jack that Mister J had parked the bike a few blocks down, inside of a warehouse. The icons blinked on and off, struggling to operate correctly.
The boot jets propelled Jack to the signal.
He landed outside of the run down establishment, and kicked down the weak, rusty entrance.
"Mister J!" Jack yelled, stepping into the darkness of the building.
The bike was parked over in a corner, which Jack saw as soon as the night vision feature kicked in.
Like Ron said, the suit was having some minor technical difficulties. Every few seconds, the night vision would cut out, rendering the hero blind.
He looked down on the floor, to see a trail of blood.
He slowly followed the trail, as it led him across the warehouse to a stairway.
Jack climbed the steps, each one blotted with the crimson liquid.
Every other step, his vision would go dark.
He reached the top, and saw that the trail led into a small office that overlooked the area below.
Quietly, he stepped in, looking for any sign of Mister J.
Jack found that the trail ended in the middle of the room.
He bent down, and put his finger into the blood. Ron had showed him that the finger tips contained highly advanced sensors, and the suit told him that the blood belonged to him.
Which actually meant that it belonged to Mister J.
Jack's vision cut out again, and he stood up.
Why does the trail end here? he thought.
He looked up, just as his vision blacked out again.
This time, it took longer for it to boot back up.
Seconds before it did, however, he felt the light patter of something dripping on one of his lenses.
Oh no.
The night vision reactivated, but it was too late.
Mister J's twisted, smiling face came flying at him from the ceiling above. He had been hanging from the metal beams that riddled the space.
Jack fell to the ground, as Mister J began to throw punches like crazy.
"I still have a chance, Bat!" he shrieked between hits.
"You haven't won yet!" shouted Jack, throwing Mister J back.
The nightvision showed the clown hit a wall, and then it cut out.
"You had some nifty little trinkets in the armory," chuckled Mister J.
"Hope you don't mind that I borrowed some of those special lenses you use in your suit."
Jack cursed. Mister J had full nightvision.
His sights came back online, to see Mister J's foot connect with his face.
Jack flew backward, and smashed through the wall of the office.
He tried to flip around and hit the landing, but there was no time. He hit the ground hard.
"Hahaha!" laughed Mister J in a more irritated tone than before.
Jack wheezed, the wind knocked out of him.
The suit was able to cushion his fall somewhat, but he was very dazed.
He propped himself up on his hands and knees, only to get a kick to the gut from Mister J.
"Jack! Remember those little tricks I showed you?" said Ron in Jack's earpiece.
Coughing, Jack bumped his fist to his hip, and a batarang sprung out of the leg armor. He grabbed it and threw it at Mister J.
"AGH!" he yelled, falling backward.
Jack got up, his body shaky. The fall had taken a toll on him.
"Let's finish this!" shouted Jack, charging forward and landing a punch in Mister J's face.
"I agree!" shouted the villain, jabbing his knife towards Jack.
Batman's vision cut out as he ducked, just avoiding the attack.
"This is for all those poor people you killed," mumbled Jack, kicking Mister J's leg.
"This is for my friends," said Jack, elbowing Mister J in the nose.
"And this is for GOTHAM!" he shouted, kicking Mister J square in the stomach and sending him flying backward, into a pile of boxes that fell around him.
When the boxes sat still, a hand reached out, and Mister J climbed after it.
"I like that you really care about this dirtbag of a town," said Mister J, the annoyance obvious in his voice.
"I like that you embrace your heritage," added Mister J.
"But what I don't like," he shouted, trudging toward Jack.
"Is the fact that you think you can win!"
Mister J pulled out a gun, and fired up above.
Jack looked up to see a massive storage container, the rope to which had just been severed.
He jumped away, as the box smashed down.
But Mister J hadn't realized was that it was full of dangerous chemicals.
Liquid flooded out of the container, over Jack and Mister J.
Jack wiped the slime off of his suit, and sloshed over to Mister J, who was completely exposed to it.
"AH! AH! AH! AHAHAHAHAAHHAHAHA!" shouted Mister J, as his skin burned.
Jack backed away, as Mister J laughed insanely.
"What's the matter, Jack-o?" asked Mister J, trying to hide the pain.
The skin color that the nightvision could pick up was completely washed away. Mister J was as white as a ghost.
"It feels... It feels great. I'm not gonna lie, Bats! YOU SHOULD TRY IT!"
Mister J leapt forward and grabbed Jack's mask, pulling it away.
"NO! ENOUGH!"
Mister J's hand was covered in the chemical, and he slowly lowered it to Jack's face.
"This is what you get for turning my people against me," said Mister J.
"We were never with you from the start," said a voice in the distance, as a card flew into Mister J's head.
Mister J tumbled backward, and collapsed on the ground.
Jack turned around, putting on his mask.
When the night vision re-activated, he saw Mister J's last Batz member standing there.
"Maybe I should have asked you to come along after all," said Jack.
The man nodded, and proceeded to remove his mask.
Jack was shocked to see a troubled, damaged version of his face. His brother had very short hair, presumably the result of a buzzcut.
Long scars ran from the corners of his mouth and up his cheeks. His eyes were dark with a permanent sadness.
"What did he do to you?" asked Jack with astonishment.
The figure just smiled sadly, and put his mask back on.
"Too much," he said.
Together, the brothers stepped back outside, leaving Mister J to rest in peace.
The citizens of Gotham were winning. They were pushing back the Jokerz, under the glowing image of a bat in the sky.
"You have done well. Chance would be proud," said the Bat.
"Thanks... What is your name?"
"Alfred," said the man.
"Thank you, Alfred," said Jack.
By the end of the night, the war was won. All of the Jokerz were either killed in battle or captured.
The citizens of Gotham raised a flag displaying a spray-painted bat, cheering.
Jack returned to the Batcave with Alfred. The Batmen clapped. On the Batcomputer, a news channel was broadcasting that Gotham citizens had managed to free themselves, and had reestablished the connection to the outside world that the Jokerz had cut off. Jack was shocked to hear that special defense weaponry was also shut down. He had never known that Gotham was so isolated.
There was also talk of a nuclear weapon deep in the heart of the city, that would've been triggered if anyone had tried to breach Gotham. A city called... Metropolis, was sending people to investigate it and help the citizens restart Gotham.
Nick held hands with Gwen, who smiled. She was back to her normal self, the shock of her injury got rid of any remaining effects of the Joker toxin. Rodney sat in her lap, holding onto her. Mr. and Mrs. Dominic hugged Jack. The kids cheered. The day was saved. Gotham was once again free of the Jokerz.
"Nice job, Jack," said Carl, patting him on the back.
"Thank you," said Cathy, giving Jack a kiss on the cheek.
Greg smiled and said, "Our firstborn won't have to grow up under Jokerz jurisdiction."
Jack smiled at Cathy, who looked at her stomach affectionately. He hadn't noticed, but she had a small bump forming.
The day was theirs. Gotham was no longer a victim to criminal tyranny. It belonged to the people.
