Meanwhile at Gotham City, a Regime vehicle stops in that area as Joker is driving it with a Regime officer, who presumes to be dead, at the passenger seat.

"Thanks for the ride. You're a funny guy."

He pauses as if he's talking to him.

"Are you sure the old gang lives around here?"

He pauses again.

"True... Here they could be dead."

Joker pause again but this time he pretends to make a surprise gasps.

"Law-abiding?! Bite your tongue!"

Joker gets out of the Regime vehicle while Batman, Y/N, and Kyoka looks at him from above. Joker looks around and see a graffiti of his face and name.

"Interesting... My fame precedes me!"

Just then as he hears the subway train from above, he turns around to see Batman flying towards him but Joker manages to kick him, knocking him down. Y/N and Kyoka quickly landed next to him to protect him from Joker as he laugh.

"Right in the belfry!"

Batman tries to get up.

"Please, don't go...."

Y/N goes over to Joker.

"Shut it, clow---arrgh!!"

Joker kick her straight in the chest, grab her by the hair, and threw her towards Kyoka as they slam against each other. Batman was about to attack him when Joker kicked him and made him fall, causing him to injure his left leg.

"Awww, did you hurt your leg? How 'bout a broken neck to go with it."

With the disadvantage Batman has, Batman tried his best to take down Joker but the Clown Prince manages to use this opportunity and takes him down with ease since Batman can't use most of his skills due to an injured leg.

"And now, my sour-faced flying rodent... Let's put a smile on that puss."

Joker was already preparing his own Joker toxic spray can as he hold Batman's face. He was about to spray it until he sees two familiar figure flying towards them from above.

"Such a beautiful moment can't be rushed..."

Joker slam Batman's face on the ground and pats his hand on Batman's head.

"Don't go cheering up without me!"

Y/N and Kyoka soon got up and were about to help Batman when he gestured them to go hide and looked up to see where Joker saw. They hesitate but did what he told them to as they manage to hide behind one of the buildings and watches Yellow Lantern and Regime Hawkgirl, wearing a different armor and wielding a different mace design, landing near the injured Batman.

"Batman. S'been a while." Yellow Lantern said.

Regime Hawkgirl grabbed Batman.

"On your feet. Let's go."

"I don't think so, Hawkgirl--"

But Regime Hawkgirl pushes Batman aside for Yellow Lantern to punch him in the face. Y/N and Kyoka gasp in horror as they knew that it isn't their Green Lantern or their Hawkgirl as they look completely different. They watch helplessly as Yellow Lantern and Regime Hawkgirl carry the unconscious Batman and takes him away in the sky. Y/N and Kyoka came out of the hiding looking at it. 

"We have to save him and find our friends." Y/N said.

"Yeah. We should hide our identity." Kyoka suggested.

Y/N nodded in agreement as Kyoka brought two hooded jackets.

"When did you get those?"

"I'm always prepared in case my jacket's ripped."

"Smart."

They put on their jacket, zipped it up, and placed the hood over their head as they hide through the shadow trying to find a way out. They were still in the alley place filled with abandoned buildings and more. What they didn't know is that they were about to bump into Izuku and his friends until their back was pressed against each other and they pulled away with a yelp. Izuku, Katsuki, Eijiro, Shoto, and Denki were about to fight them when Kyoka's eyes widen and pulled the hood down to reveal herself.

"Guys! It's me and Y/N!"

"Jiro! Y/N!" Izuku smiled in relief.

"Y/N!" Eijiro and Denki exclaimed with a smile and hugged the hooded Y/N.

"It's good to see you two as well." Y/N laughed.

"I'm guessing you guys were sent here as well." Kyoka said.

"Yeah. And we're trying to find the others." Shoto confirmed.

"Well, our Batman was taken by Yellow Lantern and Hawkgirl."

"What?! Why would they do that?" Izuku asked in shock.

"Let's just say they're NOT our Hawkgirl or Green Lantern as we recognized Hal's face." Y/N added.

"What the hell? So we're in some sort of evil dimension? Great..." Katsuki groaned, crossing his arm.

"We'll just have to find a way to—"

"'Ello everyone!"

They froze at the sound of a familiar cheerful voice and turned to see Regime Yuga approaching them with a creepy smile as he wore a complete different armor with a mask on his right eye.

"It's a pleasure to be here. The day seems to be very bright!"

"Aoyama?! Why do you look so different?" Izuku exclaimed in shock.

"That's not our Aoyama..." Kyoka said in seriousness.

"You are correct! We heard that there are duplicates that look like us! Isn't this surprising?" R.Yuga giggled maniacally.

"Hey~ What's this am I seeing? A double me? I look ugly."

Izuku's face turned pale to see a smiling Regime Izuku who's wearing a nice suit and black gloves as he had dark bags under his eyes as R.Izuku stand beside R.Yuga.

"He looks hideous." Katsuki grimaced in disgust not expecting to see an evil Izuku.

"And creepy..." Eijiro added, feeling uncomfortable.

"This is weird..." Y/N muttered, making sure her eyes glow red ready for action.

Regime Yuga and Regime Izuku didn't notice Y/N yet since she's still wearing a hood over head. Another footsteps approaches and they saw Regime Shoto and Regime Tenya.

"Huh. So it's true." Regime Shoto said with a glare, spinning his ice scythe.

"Never expect to see them. But you all are not welcome here." Regime Tenya said with a silent stare as if he's a very serious businessman.

"This is getting weird, guys. I don't like this..." Denki gulped.

"So you join their evil side?" Shoto questioned his evil twin.

"Because I get to finally kill my old man that ruined me and my family. This scar reminded me of him and I will never resemble him, even that ridiculous red hair." R.Shoto said with hate.

"You what?! That's too far! Killing him won't make you a better person!" Kyoka exclaimed in shock.

"Maybe for you. But I didn't regret one bit. I'm now the better Endeavor than he was."

Shoto growled that he would do such a thing. Sure, he hates his old man, but he didn't deserve to die not when he's actually trying to fix his family. He brought out ice glaciers towards R.Shoto who quickly blocked it and sliced the ice with his own ice scythe. R.Tenya charged Kyoka and Denki in speed when Izuku zoomed in and tackled him to the ground. Katsuki and Eijiro are fighting against Regime Izuku who couldn't help but laugh as he was enjoying making Katsuki angry while easily kicking their butt. Denki, Kyoka, and Y/N dodged the incoming laser from Regime Yuga as he kept shooting them.

"I'm surprised that you're back from the dead Kaminari! Maybe I should send you back to heaven with sparkles!"

"What are you talking about?! EEP!!" Denki shrieked, dodging another laser.

Y/N managed to get away from the crazy R.Yuga and found Shoto having a hard time fighting his evil twin as they blast out fire against each other. She quickly comes to Shoto's rescue and kicked R.Shoto straight in the chin, causing him to fly towards the trash cans. Shoto nodded to her in appreciation and he looked over and his eyes widen and he quickly tackled her out of the way when the laser nearly shot them. Shoto helped her up as they went back to fighting. Y/N's ears twitch and turn a little too late to see R.Shoto up and swung his scythe towards her. She managed to back away from him but with a swift spin, R.Shoto hit her by the handle of the scythe right by the cheek. Her hood was removed to reveal Y/N's face as time slowed by until it went back in time and Y/N collapsed on the ground with a grunt. Regime Shoto's breath hitched as his eyes widen to see her in person. She glared up at him, rubbing her cheek.

"I can't believe you hit the lady!"

"Y-Y/N...?"

That name made everyone stop, especially Regime Izuku, Regime Tenya, and Regime Yuga.

"Is that really you?"

"Of course it's me. Who else would it be, you criminal?" Y/N scoffed, getting up to face him, but what he did shocked her and her friends.

Regime Shoto traced Y/N's face with his finger.

"W-What are you doing?"

"You're really here."

"Y/N..."

She turned to see R.Izuku approaching her with wide eyes as they look like they were about to burst out tears and his hands were raised up ready to touch her to make sure it is Y/N as Regime Tenya followed. Regime Yuga watched in shock to see Y/N here and alive as he feels... happy. Izuku, Katsuki, Shoto, Eijiro, Denki, and Kyoka watch in confusion on what was happening right now.

Regime Shoto pulled himself away to let Regime Izuku and Regime Tenya go near her. Regime Izuku places his hands on Y/N's cheeks as if he haven't seen her for a long time.

"Y-You're alive?" R.Izuku croaked out as tears started to spill for the first time for him.

"Y-Yeah... But am I supposed to know what's going on? Why are you guys like this?"

"Y/N..."

She turned to Regime Tenya and see him shaking as tears fell.

"You were gone since Superman killed you..."

This made her and her friends who are not the Regime are shocked at what they're hearing.

"Y-You mean... You're Y/N doesn't exist here anymore?" Izuku shakily said.

"No way..." Eijiro said in shock.

"Is that why you all look like a bunch of villains, you idiots?" Katsuki questioned.

Y/N was speechless as she faced the multi-version of her friends.

"I..."

All the moments was cut off by something being thrown at them towards their feet and they look down to see some sort of bomb. It released out smoke and covered the area they are in. Everyone started to cough. A pair of hands grabbed Y/N from behind as the familiar floating gloves grabbed Izuku, Katsuki, Eijiro, Denki, Kyoka, and Shoto as they guided them a way out.

Once the smoke was cleared out, the Regime Class A students look around to see their twins including Y/N are gone. Though, they were silent as they took everything of what was happening until Tenya silently brought his finger up to his ear and called someone.

"Mina... There's something you should know... Make sure to tell him as well."

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Y/N, Izuku, Katsuki, Shoto, Eijiro, Denki, and Kyoka were confused on what was going on until they were cleared. They turned to see two strangers that saved their life until they revealed to be the people they never expect to see. Insurgent Toru and Insurgent Katsuki who's covered with grenades.

"I'm sure you all have questions, but we'll explain later." I.Katsuki said before turning to Y/N.

"Wow... Katsuki. You look more... dynamite."

"That's my hero name. You're the one who came up with it." Katsuki smirked proudly.

I.Toru hugged Y/N rather tightly as she began to burst into tears like water fountain.

"Y/N!!! OH MY GOD!! I MISSED YOU!!!"

"T-Toru!! C-Calm down!" Y/N struggled to get out of her tight grip.

I.Toru immediately let go of her.

"You may not be my Y/N, but it's so good to see you again."

"Can someone please explain what is going on here?" Shoto demanded.

"Listen here, Half-N-Half Bastard, I'm not the one in charge here. Ponytail will explain once we--"

I.Katsuki was cut off by loud explosions. They ran off to see what's causing it. As they ran along the way, I.Katsuki glanced at Y/N feeling beyond happy to see her as well.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

While Y/N and her friends follow where the explosions was, at Stryker Island where Regime Superman and Regime Wonder Woman are walking towards the jail cell where Batman is being held while multiple Regime guards form a line to greet him. Inside the jail Yellow Lantern has already unmasking Batman and removes his utility belt, making sure he has no tricks up his sleeves while Batman is being chained up the wall from his hands and legs.

"Okay, Bruce...Ready for visitors? Want a comb?"

As the door opens Regime Superman and Regime Wonder Woman enters while Regime Superman scan him while Bruce is in shock.

"Nice work, Hal. How did—" R.Wonder Woman said.

R.Superman cut her off.

"It's not him."

"What?" Yellow Lantern asked in shock.

"His DNA matches Bruce Wayne's, but his vitals are all wrong. You're one of the duplicates. Tell me why you're here."

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Back at Gotham, Joker is standing on top of the stage at the abandon Arkam Asylum Mess Hall where Harleen who's dressed in a red and black punk outfit with cowboy boots and the Joker Clan are cheering for Joker and hearing his speech.

"I love what you've done with the place. Arkham is never looked better."

The crowd cheers for him while Harleen claps for him.

"Dear members of the Joker Clan... You know the truth about the Metropolis Incident. Superman killed those people. Then he tried to kill me."

The crowd starts booing and shows thumbs down about this matter.

"I admire the work you've done in my name... Disturbance... Distractions... General pains in Superman's buttocks."

Some of the members started to laugh about it.

"But let's think bigger."

"Ain't he dreamy..." Harleen sighed in love-struck as usual.

Joker moves away from the podium and blows a kiss at Harleen and continues the speech.

"Harley tells me Superman made this pill for his thugs. Then Bat-Boy's Insurgents got some. Now we have them too."

He shows out the pill.

"With these a bus can fall on us and we won't be hurt! Slapstick at its finest!"

The crowd cheers as Joker ate the pill and swallow it. Joker then kneels down and asks them to be silence before he finishes his speech.

"From now on we'll be more than a nuisance. The barking dog will become the rampaging elephant. The whoopee cushion, a land mine!"

He then stands up.

"The joker... A KING!"

The crowd starts to cheer for him until the walls of Arkham Asylum broke down as Regime soldiers came down shooting everyone. Joker manages to sucker punch one of the soldiers and toss him down the stage. Suddenly another Regime soldier appears and shoots at Joker but to Joker's surprise he is still alive, uninjured.

"I should be dead! Thanks, Happy Pill!"

As Joker grab the soldier's gun to hit him back, Regime Hawkgirl and Regime Nightwing enters in the fray. However, Nightwing didn't see Joker and run pass him while joining the fight but Hawkgirl notice him and grabs him up in the air. Harleens tries to saves Joker by shooting her down but Hawkgirl was too high for her to get hit. With no other choice, Harleen takes out a device that she receives from Insurgent Batman and press it to call for reinforcements.

"Back from the grave? Shoulda kept that suit buried." R.Hawkgirl said.

"It's not my Sunday best. But it's comfortable. And functional."

Joker uses his flower in his suit to squirt acid on her, forcing Regime Hawkgirl to let him go. Joker lands safely as Hawkgirl lands while getting ready her mace.

"I'm gonna enjoy giving you to Superman."

"Oh not tonight, dear. You have a headache."

With the Super pill he ate, Hawkgirl's attack was merely like a paper cut to him. He knew that she too had ate the pill that Regime Superman gave and test it by shooting at her point blank. This didn't leave a scratch as Joker's theory proven right. So he decides to knock her out by taking her own weapon and slamming her into her face, which oddly it works.

"Lovely girl. If you can get past the feathers..."

Patting his knife on his hands, Joker decides to cut her wings off. Just then Regime Nightwing finally notices him after taking down one of the Joker Clan members.

"Joker!"

Before Joker manages to cut her wings, he was knocked away by Nightwing's Batarang. Joker then decides to use his playing cards.

"Pick a card!"

Joker toss his cards at Regime Nightwing as it explodes after multiple cards connect to him. However Nightwing doesn't give up.

"Joker dies here!"

After successfully tossing more cards at him; forcing Regime Nightwing back due to the explosions...

"I'LL KILL YOU, CLOWN-BOY!"

After successfully exploding him twice using his cards, Joker gave up and tosses the remaining cards on the floor while Regime Nightwing jumps near him, confronting the Clown Prince.

"So the Bat-Brat joined Superman...Tell me: Who's boots are tastier to lick?"

"Batman's a criminal. Just like you."

"Nothing like me."

"So you're a hero where you come from?"

"Oh not, dear boy. It's just that Batman corrupts young minds while I... BASH THEM OUT OF THEIR SKULLS!!!"

After a couple of rounds, Joker realizes he's not the same Nightwing he fought as he's much more brutal and reckless. So Joker decides to take him out with a smile as he always does. He takes out the pie that he has from Harleen during their battle and tosses it into Nightwing's face the moment Nightwing begins to attack. Getting stun by the pie on his face, Joker hits him with his crowbar a couple of times, shoot him in the face and grab the nearest fire hydrant he sees to knock him down. The moment Nightwing was knocked down onto the ground; Joker takes out an RPG that he stole inside the Regime vehicle he was in. Before Nightwing manages to regain his senses, suddenly Joker puts the RPG near his face saying "Wakey! Wakey!" and shoots him. This causes Joker to fly back, dropping down to the ground unharmed and unscratched. Nightwing on the other hand was knockout by the blast unconscious with his body still intact.

"I have to tell Batman...there's been a death in the family."

Joker was about to kill Regime Nightwing but he was interrupted by Insurgent Batman, Momo, Hanta, and Mezo and the prime heroes' and Class A's arrival. Not only that, but Y/N and her hero friends along with two members of Insurgent came along right in the nick of time. Regime Hawkgirl (who happens to wake up during Joker's battle) was battling one of the Joker Clan's members was surprise by this and gets a couple of hits by Aquaman. Unable to see victory in this, she decides to retreat while flying towards Regime Nightwing's side.

"We're outnumbered! Let's go!"

She takes out her gun and shoots above and retreats from above while carrying the unconscious Nightwing; leaving an angry Joker for unable to kill both of them while he has the chance. Once everything settles down, while the Joker clan tries to regroup and helping the survivors, Insurgent Batman and Wonder Woman meet up with Harleen.

"You can turn it off now." I.Batman said.

"Thanks for the assist, Bats."

Suddenly, Joker walks casually towards them while putting his hands onto Harleen as both Wonder Woman and Insurgent Batman are shocked to see him here.

"Hi gang! What'll do we do now? Anyone up for pancakes?"

"Joker!"

Wonder Woman goes behind Joker and arm to his back in order to restrain him.

"What. OW! Why does she hate pancakes?"

"Not funny!" Denki growled.

"Kaminari? You're back?" I.Hanta asked in shock to see him.

"Back? I'm not from here if you assume. Something happen to the other me?"

"We'll explain later." I.Momo said, turning to Y/N as the rest of the Insurgents finally see her.

"Y/N..." Mezo gasped.

"It's you.." Hanta gasped out.

"Yeah. I'm just Y/N. Just Y/N. Not the Y/N you know."

"We know.."

"What are you playing at, Harleen? What's he doing here?" I.Batman demanded.

"Mr. J here can be a big help to us--" Harleen said.

Joker casually agrees with her while Green Arrow and Aquaman joins in.

"So you came along on our little field trip..."

"And I'm guessing he didn't arrive alone. Where's Batman?!"

"There's one!"

Joker points at Insurgent Batman.

"Right there!"

Unamused with his answer Wonder Woman pulls his arm again, paining him.

"Your eyes! Pure evil. Just like his."

"Who? Superman?! His flying friends took Batman. My Batman. Our. Batman."

"Quiet! Or I'll cuff you and leave you for the police."

"He's telling the truth. We saw it." Y/N said, looking at I.Batman and knowing that's not her Batman based on the different costume he's wearing.

"I see."

"Then why did you save me from them?"

Joker gets his arm pulled up again by Wonder Woman.

"OW!"

"Batman's been captured, we gotta bust him out." Green Lantern suggested.

"I agree." Kyoka said.

"To free your Batman we need to complete our mission." I.Batman explained.

"Ooh, I love a good mission." Harleen smiled.

"Negative. You and your Clan lay low. You're a target now."

He then turns to Joker and grabs him from Diana.

"And you're too dangerous to run free. More of them will be here soon. Go. I'll catch up with you. Momo, you're in charge."

He proceeds to drag Joker away.

"I don't like you." Joker said.

"Let's go. I'll explain along the way." I.Momo said, leading them the way out.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Back at the Prime Dimension, Superman, Flash and Cyborg are in the Watchtower finally found their missing teammates and students at the meeting hall.

"So you found them. A parallel dimension... Now how do we get there?" Superman asked.

"We don't We pull them here." Flash said.

"No risk to an away team... Good. Still the same problem, though... How do we do it?"

"With this."

Cyborg clicks one of the controls and a screen pops up showing a 3D device.

"We're gonna modify my Cosmic Treadmill. Pull them all back at once."

Both Superman and Flash nods in agreement.

"We've got some work to do."

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Back at the Injustice Universe, somewhere in Metropolis, Insurgent Lex is standing on the rooftop looking at the full moon above while Insurgent Deathstroke, who's in full armor, walk towards him.

"Beautiful, isn't it..." I.Lex started.

"The moon? Or its light shining off your bald head?" I.Deathstroke joked.

"I'm pleased you wanted to meet. You're finally ready to join our little club?"

"Business is bad. Being hunted is worse."

"After so many refusals... Why now?"

I.Deathstroke pauses for a moment.

"They made it personal."
