In the abandoned hotel, a familiar black spiky haired boy was sitting on his bed staring at the picture of himself and Y/N. He wears an evil costume as he's part of the Regime.

He closes his eyes grimacing at the flashback of Y/N's death he clearly cannot forget and remembered himself crying for her to come back and stay with him. It made him wish it was just a nightmare and that everything is alright. But sadly, the world is cruel enough to make it a reality.

"I missed you..." Regime Eijiro whispered out.

A door was knocked, making him not bother to look as he asked.

"Who is it?"

"It's me, Mina."

R.Eijiro sighed, clearly not in a mood for another 'criminal' hunt and kill.

"Come in."

The door opened to reveal Regime Mina as she walked in, looking worried and concerned for her friend. Her hair is much longer than how her pixie was and wears an evil costume familiar to her old hero costume.

"You doing alright, bud?"

"Yeah..."

Suddenly, R.Mina fiddled her fingers nervously.

"There's something you need to know. It's about... the duplicates that look like us and... Y/N."

R.Eijiro's eyes widen if he heard it right. He looked up to see that she's serious. He immediately stood up, holding the picture still.

"Tell me everything."

R.Mina nodded without hesitation.

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

Meanwhile, at the abandon Wayne mansion, which is heavy protected by a force field, Insurgent Batman and the prime heroes are near the area while Batman tries to disarm it.

As for U.A. Students, the prime U.A. Students are taking in the shocking information from Insurgent Momo, especially Y/N. She couldn't believe her other Anjali is dead and asked about Gunner and Feather, luckily they're alive and are being hidden for protection. Denki even questioned Insurgent Momo about Yuga saying that he was brought back from the dead. She sadly told him that after Superman took over, they've been trying to find some food and allies in order for them to survive and to find ways to take down Superman and the Regime. Though some never make it. Insurgent Denki died to protect them from the Regime that attends to kill them or arrest them for stealing food. As for the others, Mineta was killed by their so-called friends from attempting to spy on them, Koji went missing, Rikido died from sickness, and Mashirao died to protect Toru from Insurgent Raven who spotted her.

"Musta been some party. Superman did this?" Aquaman asked.

"Exposed my identity and froze all WayneTech assets. Made Bruce Wayne a non-person." I.Batman replied.

"I still can't believe he lost it this bad. Even with what Joker did." Green Arrow said.

"No kidding..." Ochaco sadly said.

"In Superman's mind, he destroyed Metropolis." I.Batman said.

"I'm not followin'..." Green Arrow said in confusion.

"Somehow Joker altered Superman's mind so he believed he was fighting Doomsday... but it was Lois. Joke linked the nuke's trigger to Lois' heartbeat. When she and the baby dies, Metropolis died with them."

"Shit..." Katsuki muttered.

"I feel so sorry for him." Izuku frowned.

"Superman was vulnerable. Probably for the first time in his life." Wonder Woman said.

"His fear won out." Green Lantern added.

"Like the same thing happened to us..." I.Momo said, looking at Y/N.

"Green Arrow died trying to explain that to him." I.Batman said, causing Green Arrow to be shock and silent for a moment.

"Alright. Movin' on."

Soon the force field turns off, knowing it is safe to enter.

"What's with all the security? I mean, he already trashed the place." Green Arrow questioned.

"Would you take any chances with me?"

All seems to agree silently.

"I need to crank up the Batcave's back-up generator."

Insurgent Batman then turns towards Aquaman, I.Momo, and Kyoka before facing the others.

"You three are with me. You all secure the Batcave entrance. It's in the study."

"That's a great plan, Spooky, but, uh, isn't this your show?" Green Arrow said.

"Splitting up saves time. And you're the best suited to take out the automated sentry guns."

"Alright then. Operation Thunder Eagle Lightning... whatever... is underway!"

They split up as Green Arrow already taken out multiple sentry guns with the help of Denki's Quirk as he electrified them. They then take a peep at the study room's entrance.

"Over there."

However they sneak in silently as they realize that there's some cold air coming out from below, knowing someone is there.

"Cold..." Green Lanter said.

"Not me." Shoto said.

Green Arrow agrees as he asks Hal to check first. Unfortunately, once Hal tries to open the door, he got knockout along with Shoto by a furious blizzard wind that suddenly burst the door open.

"Oh shit..."

Wonder Woman and Green Arrow, and U.A. Students enters as Oliver shot the arrow at whoever's in the room but the arrow freeze as it drops near the culprit revealing Regime Killer Frost with a Mohawk hairstyle. She was not alone as a bald Regime Solomon Grundy, with his prison outfit, was beside her. 

"Killer Frost..." Green Arrow said.

"Grundy! Play time!" R.Frost ordered.

"ARROW MAN!!!"

While Wonder Woman takes care of Regime Killer Frost and the rest runs off to keep going on their mission as Wonder Woman ordered them to while Ochaco and Tenya check on Shoto and Green Lantern, Green Arrow goes after Regime Grundy. With his agility, Oliver manages to smack him with his special made bow even using his smoke arrow on him but he accidentally leaves an opening for Grundy to attack.

"Oh shit."

Regime Grundy caught him and head-butt him. Both traded blows as Grundy later toss him aside.

"ARROW MAN HURT GRUNDY!"

Green Arrow decides to keep shooting him and it manages to send Regime Grundy back due to the explosion after shooting Grundy multiple times.

"Arrow man smash Grundy!"

Regime Grundy resort into throwing weapons at him but this doesn't stop from being hit by Green Arrow's sharp shooting skills.

"Squash Arrow Man!"

Regime Grundy decides to use furniture to stop Green Arrow from shooting him but this method also fails.

"Pile of composed."

"Kill Arrow man!"

Finally Regime Grundy decides to get serious after the last explosion.

"GRUNDY HURT ARROW MAN!"

Despite getting hit a couple of times, Oliver is amaze that he didn't get bruise up due to the pill he has ate. So Oliver decides to tie him up with his bolo arrow near his legs, hit him a couple of times to stun him a bit and shoot three explosive arrows at close range. The moment it explodes, Oliver was amaze that despite being push back by the explosion, he looks fine but for Grundy he was knockout.

"Huh... Looks like the Indestructo Pill works."

Just then, Hal regain conscious as he's still trying to get back on his feet while entering the room while Ochaco and Tenya help him, looking at the fight between Wonder Woman and Regime Killer Frost. Oliver was about to shoot Killer Frost when Regime Grundy gets up on his feet, knowing he's going to be attack by him again. Shoto got up after Hal and watched as the fight went on.

"Aw, for the love of--- LANTERN! "GRAND SLAM""

By cue, Green Lantern flies in and uses his green baseball bat and hits Grundy away through the roof. Hal then chase after it.

"You kids have fun! Stay outta the street!"

Ochaco and Tenya deadpanned at that. Unfortunately, while both women do sword fights, Regime Killer Frost manages to freeze Wonder Woman.

"Stupid Amazon..."

But Green Arrow shot an explosive arrow on the ice, breaking Wonder Woman free. Ochaco and Tenya quickly helped her up and ushered her aid. This doesn't please Regime Killer Frost as she keeps attacking her ice projectiles at him. But Oliver manages to guard her attacks and counters back once she gets near him.

"That wasn't very nice, Snowflake."

Killer Frost manages to freeze most of his arrows with a breeze but Oliver's tricks aren't finish. He purposely missed an arrow on the floor and shoots a fake one at her. Killer Frost didn't see it coming as when Killer Frost was ready to freeze his next arrow, the arrow on the floor suddenly explodes, hurting her a bit causing her to get hit and knocked out by his electric arrow.

"Thought that'd warm me up..."

Shoto comes over and freezes Regime Killer Frost up to her neck, immobilizing her.

Just then Green Lantern returns.

"What'd I miss? Everything cool?"

"Frosty. How's Grundy?" Green Arrow asked.

"Weightless. In orbit."

Wonder Woman, Ochaco, and Tenya joins in, surprise to hear Hal's words...

"You didn't..."

"Is it normal?" Ochaco asked.

...followed by Insurgent Batman and Aquaman, and Insurgent and Prime U.A. Students who just arrive.

"Grundy's a zombie. He'll be fine. Let's go. It won't be long before Superman knows we're here."

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

Meanwhile Insurgent Lex Luthor was visited by his 'best friend' Regime Superman in his office.

"So you need some sort of scanner. To help identify these duplicates?"

"Exactly."

Regime Superman takes out a red thumb drive.

"This is data from the duplicate Batman I'm holding at Stryker's."

He gives it to Insurgent Lex.

"That's helpful. It's still going to take a few weeks."

"You'll figure it out. You always do."

"Glad to be of service."

Regime Superman gets up from the sofa as Insurgent Lex shakes his hands.

"No dinner this evening? Stephan has a new shipment of that Kansas beef."

"Next time."

Regime Superman walks for a few steps until he stops and realizes something.

"These duplicates. Do you think there's a Lois where they come from?"

Insurgent Lex sighs.

"There was only one Lois."

Regime Superman was about to say something but gave up and leaves while Insurgent Lex just looks at the thumb drive. Back at the Batcave, Insurgent Batman and Insurgent U.A. Students and the other prime heroes and U.A. Students are inside the elevator heading down to the Batcave.

"I've never seen the Batcave. Our Batcave, anyway. Should be... interesting." Green Arrow said.

As the elevator door opens, they see the Batcave is deserted yet it's not in ruins. Some of the machines and vehicles still remain intact as Batman turns on the main computer.

"How did you hide anything in here from Superman? Looks like he was pretty thorough."

"The cave walls are injected with lead polymer. There's no way he could find what we're here for." I.Batman explained.

"Sounds environmentally safe... You sure went to a lot of trouble. Between this and the DNA..." Green Lantern said.

"Neutralizing Superman was not a call I could make alone. So I put the weapon in a vault that only opens by simultaneously sampling DNA from Superman's closet allies."

"Our counterparts." Green Arrow said.

"With my Green Arrow dead, and the others backing Superman's insanity, I needed you. Your matching DNA."

After clicking some buttons at the controls, he goes to a wall, touching it to find it.

"It's behind there. Lantern..."

Green Lantern does as he was told as he uses his green jackhammer to drill the wall. Upon finishing it, pieces of rubble drop down with one huge rock as Batman points at the huge rock.

"That one."

"A rock...You're gonna throw a rock... at Superman..." Green Arrow said in sarcasm.

Insurgent Batman walks a few more steps as he stops them, takes out a remote button and clicks it. In front of them shows red glowing light, heating up the floor as it forms a pentagon shape floor. It then opens up another control panel rising up upon them.

"Whoa..." Denki and Eijiro awed.

"Hands on the scanners." I.Batman said.

Everyone except the U.A. Students goes to their respective panel as each has its own hand recognition and color while Batman places the large rock at the center of the panel.

"Yellow..." Green Arrow said displeased.

"Computer... Begin recognition scan..."

It does as it confirms all five members as the rock begin to head up and breaks into pieces. Insurgent Batman takes a look and inside the rock is a briefcase. Opening it, he finds pieces of Kryptonite and a weapon inside, the one he's looking for. He then closes the bag and takes it.

"A Kryptonite weapon, huh." Y/N commented.

"That's it. Let's move."

Suddenly, they hear a rumbling sound, knowing someone is trying to enter the place through the rocks. With not a moment to lose, Insurgent Batman quickly hides the briefcase somewhere safe as they see Regime Wonder Woman, in her Amazonian armor with the bald Regime Black Adam, flying towards them after the prime heroes and students ready their weapons and Quirks. Y/N and Eijiro were shocked to see Regime Eijiro and Regime Mina.

"You..." Wonder Woman glared.

"Let your guard down at your peril."

Regime Black Adam tackles Wonder Woman aside while Green Lantern and Aquaman, Izuku, Tenya, and Insurgent Hanta help her, leaving only Regime Wonder Woman to Green Arrow (although it is possible Insurgent Batman goes after Regime Black Adam.) Green Arrow shoots an arrow at Regime Wonder Woman, which causes it to explode as it gets close to her. Green Arrow was arrogantly pleased about this.

"Our Green Arrow was just as arrogant." R.Wonder Woman glared.

"And probably just as handsome." Green Arrow smirked.

Unlike his Wonder Woman, she was way reckless and more dangerous even underestimating him. It was a bad idea as she was taken down easily by Oliver's tricks when he uses his arrows to grab her and blast some other arrows to knock her out unconscious.

"And another thing: Our Wonder Woman is better looking."

With Regime Eijiro and Regime Mina...

"Eijiro? Mina? You're with them?!"

"Y/N..." R.Eijiro said with wide eyes.

"Sorry, Y/N... Nothing personal." R.Mina frowned and started to blast them with her acid.

Luckily, I.Momo created a shield to cover them. Eijiro and Regime Eijiro charged each other and punched each other's fist with their hardening. Kyoka kicked R.Mina straight in the chest and Y/N quickly restrained R.Mina as Kyoka earphone jacked her, causing her to scream.

"Sorry, Mina."

Y/N looked over as Eijiro and R.Eijiro kept punching and punching each other until R.Eijiro managed to punch him straight in the face, causing his nose to bleed.

"Eijiro!"

Katsuki growled and charged R.Eijiro and exploded him in the side of his stomach.

"Ha! You'd think that's gonna work on me, Bakugo?"

R.Eijiro smirked as he touched his side, feeling a little itchy. I.Katsuki comes behind him and punched him in the back.

"You traitor!"

"Traitor, you say. Well, you could've been a better hero if you'd just join us."

"That's not the same!"

"Enough, Eijiro! This is the line we do not cross!"

Y/N ran over to R.Eijiro and roundhouse kicked him in the neck, knocking him unconscious.

"That's a lesson for you for joining on the wrong side."

Meanwhile Aquaman is restraining Regime Black Adam from moving with his trident with Insurgent Hanta holding him still with his tape while Izuku and Tenya hold each of his arms, but Adam breaks free after flying up into the roof, causing Aquaman, Izuku, Insurgent Hanta, and Tenya to get knockout from the impact.

"Guys!!" Y/N exclaimed.

"Arthur! Kids!" Green Arrow exclaimed.

As Green Arrow shoots to tie him up on one of his hands, Insurgent Batman does the same to his other arm using his Batclaw while Wonder Woman with her Lasso of Truth. Green Lantern walks casually and ties his legs up with his ring power. Unable to hold much longer, Regime Adam loses focus and falls hard. While Oliver checks on Arthur, Hal restrain Adam with his power.

"That's enough, Adam. You're done."

"You presume too much..."

He's right as he manages to shock Green Lantern to the source, causing the entire Batcave to be overflow with lightning everywhere like a thunderstorm. Green Lantern gets knockout, followed by the Insurgent Batman and Wonder Woman who get caught by the lightning. Insurgent and Prime U.A. Students were luckily didn't get caught into the lightning as Insurgent Momo managed to create as much shield as possible and much more bigger. Green Arrow also didn't get hit after the thunderstorm dispel when he was taking care of an unconscious Aquaman, Izuku, Tenya, and Insurgent Hanta.

"Shoulda seen that comin'..."

"Only one of you remains." R.Black Adam said.

"Yeah, but I'm the one to beat."

Black Adam's the tough one. As this is what Oliver thinks. Without the help from his friends and Shazam, Oliver relies on his tricks and uses his anger to forcefully shoot him with a bolt of lightning. As he does, he shoots a mirror arrow as it reflects it right at him, knocking him out.

"And Sparky makes four."

Once the heroes regain conscious, Insurgent Batman checks the briefcase but it seems it also hits the briefcase due to the thunderstorm.

"Damn!"

"Can it be fixed?" Green Lantern asked.

"The Kryptonite's intact, but the optical resonator is beyond repair."

I.Batman close the briefcase.

"Even with Luthor, we don't have the resources to build a new one quickly."

"Looks like we're gonna need some help." Green Arrow said.

"Yeah. And fast." Y/N agreed, looking down at the unconscious Regime Eijiro and Regime Mina. "What have you two gotten yourself into?..."

Eijiro placed a hand on Y/N's shoulder to comfort her. Insurgent Batman leaves while there was a bit of silence in the Batcave.
