Meanwhile back at the Injustice universe, Aquaman, Ochaco, and Tsu visit the Royal Atlantis library and meets the royal archivist at Atlantis who bows to him.

"A pleasure most rare, Your Highness."

He turns to the U.A. Girls.

"As to you as well, Ochaco and Asui."

They nodded with a smile.

"I need information on surface world governance. History and current structure." Aquaman said.

"Ah. For the treaty negotiations with the High Councilor?"

This catches Aquaman, Ochaco, and Tsu off guard for a moment but decides to play along with the charade.

"Yes. The treaty discussions."

"I'm afraid our resources are limited. Superman has been less willing to reveal his regime's inner workings." Archivist said.

"Tell me what you know. Recount the events of his ascension."

The archivist stares at him in suspicious but Aquaman quickly gives him a reason to not raise any doubts from him.

"A thorough review might illuminate new strategies for negotiation."

"I am humbled, Sire."

He bows a bit before walking along with him around the library while telling Aquaman, Ochaco, and Tsu what he knows.

"Five years ago the criminal Joker deceived Superman into killing his wife and unborn son and destroying Metropolis. Consumed by grief, Superman killed the Joker."

Ochaco and Tsu stare at each other with wide eyes and feel bad for Superman. It sounds terrible and sad for them for losing someone they love so dear. Aquaman was just as shock as them as he pretend that he remembered.

"Yes... We all remember where we were that day..."

"Afterward he showed no restraint. Judge, jury and executioner, he and other like-minded metahumans quickly reined in the criminal element."

"Which made him quite popular."

"The surface world was desperate for strong leadership. Superman consolidated his power. He created the One Earth government. Democratic institutions were swept away."

Ochaco was about to ask about what happened to Class A when an Atlantian guard appears before them.

"Sire. The High Councilor's envoys await you in the throne room."

As Aquaman, Ochaco, and Tsu enters the throne room, they saw Regime Flash in a more futuristic armor and Regime Shazam with his black and red attire while wearing a hood. They look happy to see Aquaman the moment they see him as well as seeing Ochaco and Tsu as they asked them.

"Surprised to see you two here." Regime Flash said.

"What's up with the old outfit? Already changing your looks?" Regime Shazam asked.

"The king brought us here to welcome us and well, we... decided to at least look good and be more formal to him and Atlantis." Ochaco lied with a forced smile.

"Yeah." Tsu nervously nodded.

R.Shazam and R.Flash gave them a nod in understanding much to their relief.

"Flash! Shazam! Welcome!" Aquaman greeted them.

Both envoys bow before him.

"Your Highness. It's an honor to meet you." R.Shazam said.

"And to be the first surface people to visit Atlantis." R.Flash said.

"Yes. We have important matters to discuss. The treaty." Aquaman said.

"The final draft."

R.Flash takes it out.

"Superman is glad you've agreed to his terms."

"May I?"

Regime Flash gives him the treaty as Aquaman opens it. He walks away from them as he reads it and the girls comes to read it as well but their expression changes upon reading the condition in the treaty.

"Is there a problem, Your Highness?" R.Shazam asked. "Ochaco? Asui? You two okay?"

Aquaman, Ochaco, and Tsu turn to them with not so happy look and anger, not caring that they've blown their cover.

"This is complete subjugation. Superman will rule Atlantis!"

"Are you guys nuts?!" Ochaco exclaimed.

"Kero!"

"It's what you agreed to. It's what we expect." R.Flash pointed out.

"You threaten us? Tread carefully."

"We have our orders."

As both attacks Aquaman, Ochaco, and Tsu, they manage to dodges it while Regime Shazam accidentally shot Regime Flash. Aquaman manages to knock Regime Shazam down as Regime Flash manages to use his speed and land some punches until Tsu brought out her tongue and wrapped it around his legs and tripped him. Aquaman quickly knocks him down. Ochaco brought out her fists as she deals with Regime Shazam with Tsu by her side.

"You can tell Superman...HE WILL NOT HAVE ATLANTIS!!!"

As Ochaco and Tsu fight against Regime Shazam, Aquaman was so pissed when he got threaten and attacked by both envoy that he decides to takes out his aggression at both of them (without killing them of course). Regime Flash tries to use the same tactic to takes him down but Aquaman knows his straight forward pattern and knocks him out without hesitation.

"Your orders be damned."

Just then, Regime Shazam zaps the U.A. girls, shocking them as they fell to the ground. He the shot at Aquaman but he manages to dodge it.

"Let's not take this any further. I want to talk to Superman."

"You don't 'talk' to Superman! You do what he wants! And you're gonna do what you promised."

Unamused with his answer, Aquaman takes his anger out of him despite Regime Shazam being a kid. Shazam tries his best to take down the King of Atlantis but he was no match against him as he was a disadvantage due to being underwater and unable to use his full power against him. Aquaman throws his trident at him and successfully knocks him down. Before Shazam tries to get up, he gets a final blow into the face, knocking him out unconscious.

"You two make sorry diplomats."

Aquaman comes over to Ochaco's and Tsu's aid.

"You girls alright?"

"Yeah."

They nodded as he help them up. What Aquaman didn't realize is that while he was battling the envoys, a few Atlantian guards were surprise to see him fighting until one of the guards notifies them that their king is on his way. After Aquaman takes them down, Altantian guards came inside the throne room while surrounding him followed by Aquaman's counterpart, who has a beard and a different armor.

"There he is, Sire. Along with the outsiders."

Regime Aquaman was not amused to see this as his double also begins to realize what is going on. Ochaco and Tsu were shocked to see another Aquaman but much more different as they also realize where they are in.

"Well then. Parallel dimension it is." Aquaman said as the girls nodded in agreement.

"Who do you work for, usurper? Manta? Ocean Master?" R.Aquaman demanded.

"I'm the King of Atlantis! I answer to no one. Unlike you."

"Mind your tongue."

"I prefer our Aquaman than that guy. He looks weird with that beard..." Ochaco whispered to Tsu.

"Yep."

"You would give away your kingdom, like a pair of worn boots, to a surface-dweller?" Aquaman asked.

"The treaty requires Superman to maintain Earth's oceans. And recognize our autonomy." R.Aquaman said.

"You put your army at his beck and call."

"A necessary compromise."

"More like appeasement!"

Regime Aquaman couldn't answer as he's now seriously irritated and pissed of his counterpart's remark.

"I grow tired of this. Take him! Along with those two!"

First a guard tries to take him down but fails as Aquaman punches him and kicks him away. The second guard follows the suit but also been defeated by him. The third guard was also not as lucky as he was kick and knocked down by him. As two guards prepared to attack him together, Ochaco who swiftly touches all of their tridents and makes them float as Tsu jumps and wraps her tongue around them and Ochaco pressed her fingers together to release them. Tsu then threw the tridents towards the guards and both of them got knocked down as Tsu wraps her tongue around the guards again and uses them to knock over a few more guards with the help of Ochaco making them float after touching them.

Aquaman takes out his own trident as the three other guards come and manage to pin him down but they were no match against Aquaman's strength. Finally with no guards left to assist him, Regime Aquaman decides to take him down himself as they both end up into a hand to hand combat which Aquaman easily knocks him down. Ochaco and Tsu backed away to let them  fight.

"I had planned to offer you help. I CHANGE MY MIND!"

Since his counterpart refuse to listen to reasons, Aquaman decides to take him down despite being in the same level and in their own territory. However Regime Aquaman was a bit weaker than his double as Aquaman manages to gain the upper hand thus being defeated by his own double.

"Now let's discuss a revised foreign policy."

Unfortunately more guards came to assist Regime Aquaman.

"Kill them!"

As some of the guards were about to attack them, suddenly a red glow forms everyone except Aquaman, Ochaco, and Tsu as they froze in their tracks. Aquaman hits one of the guards who was about to attack him but the moment that the red glow appears, he falls down like a statue. He checks on one of the guards but neither of them faze.

"Um... Is this normal?" Tsu asked.

"What now..."

Just then, Injustice Ares magically appears before them.

"Ah! A demon!" Ochaco shrieked, bringing herself into Tsu's arms while holding two of her fingers up in the shape of a cross.

"They do tend to fight first, don't they... Though I may have stoked the fires a bit..."

"Ares. Why are you here?" Aquaman demanded.

"I feed on conflict. Until today I'd been starving. I sensed the return of aggression, and sought its cause."

"You did more than that. You brought us here."

"No. But I can guess who did."

"My fire doesn't need stoking, Ares! Tell me who."

"You presume to command me?"

"I do! AND YOU WILL OBEY!"

Oddly, after battling a couple of rounds at Injustice Ares he realize that this Ares is weaker than the one he knows. He tries to test this by purposely getting hit. His swords were merely paper cut than a wound. Aquaman realize that this is not the Ares he knows of and didn't go full strength to take him down. After defeating him, Aquaman comes with a conclusion about Injustice Ares.

"You're weak Ares."

Injustice Ares gets back on his feet.

"Superman's reign has nearly eliminated conflict. Left me virtually powerless..."

"So if you didn't bring us here, who did?"

"Those who would end Superman's rule. The Insurgents."

"Heroes?" Ochaco asked in hope.

"Only one. All other heroes who challenged Superman have been eliminated." I.Ares said, causing the girls to gasp.

"He killed them...And the only ones left are those who joined him?" Aquaman said.

"Along with a small cadre of former villains, whose loyalty was brought coerced."

Ochaco was about to ask since she figured there are other people that look like herself and her friends when Aquaman spoke first.

"I need to join my colleagues and my students."

"They're with the Insurgents as we speak." I.Ares said.

"Send us to them." Tsu said.

Somewhere in a hidden Insurgent base, Wonder Woman and Green Lantern are looking at Green Arrow who was about to take a pill while Fumikage was leaning against the wall with Tanya pacing around when Aquaman, Ochaco, and Tsu magically appeared before them, surprising them.

"Uraraka! Tsu!" Fumikage exclaimed in relief.

"You're both okay!" Tenya exclaimed, hugging both of them.

"It's good to see you too!" Ochaco smiled.

"Kero!" Tsu nodded.

"How'd you guys get here?" Green Lantern asked.

"Ares. Not our Ares." Aquaman said.

"We know. Meet Not-our-Batman." Green Arrow introduced.

"Along with Not-our-Yaoyorozu." Tenya added.

I.Batman and I.Momo enters in.

"I was wondering how to retrieve you from Atlantis along with the other two." I.Batman said.

I.Momo smiled, tearing up and hugging Ochaco and Tsu.

"It's been so long since I get to see you guys like this."

Aquaman noticed the pill in Green Arrow's hand.

"Headache?"

"Trying to prevent one..."

"It's a durability enhancer. Five-U-93-R."

"How can a pill allow--" Tenya asked.

"Kryptonian nanotech. Increases the tensile strength of bone and tissue by several thousand percent."

"Whoa..." Ochaco awed.

"Bats can tell you the rest later, if you're having trouble sleeping... He borrowed the recipe from Superman. Supes gives it to his flunkies."

Green Arrow gets down off the table as everyone takes their seats around it.

"Yes. We met a couple of our evil twins." Aquaman said.

"They look terrible." Ochaco commented.

"And their costumes look not hero-like." Tsu added.

"I've met mine as well along with Not-our-Tsu." Fumikage grimaced.

"I've never knew that our twins would turn evil... I wonder how mine would look..." Tenya muttered, not wanting to know.

"They're not evil. Most obey Superman out of fear... Or they believe he's right and have lost perspective." I.Batman explained.

"So you two're the only one left..." Aquaman said.

"Some of my classmates stayed with me while my own friends turn their back on me to follow Superman... Ever since Y/N was killed..." Momo sadly said, looking down.

This made Fumikage, Tenya, Ochaco, and Tsu tensed up.

"What... happen to her?" Tenya worriedly asked.

"She..."

Momo sniffed as if remembering her nightmare. I.Batman decide to explain for her.

"Ever since Superman was in charge, Y/N was terrified and angry. She beg him to do the right thing and mentioned Louis. When he refused, she tried to attack him... Which is foolish and he killed her after that... Along with Anjali who's in rage to see her owner killed. It was... devastating for Class A. I wish I was there to stop it."

They were shocked at hearing such news. If their Y/N is out there, this won't end well.

"I... I'm sorry.." Ochaco frowned.

"But our Y/N is still out there. She could be anywhere." Tsu said.

"We gotta find her before they do." Fumikage suggested.

"I know. That's why I brought Dynamite and Invisible Girl to go and find her and the others." I.Momo said.

They were relieved to hear that. Just then a familiar person wearing his business suit enters the room.

"Not just the two of them..."

It was Insurgent Lex Luthor.

"What is this?!" Aquaman demanded, not happy to see him.

"Not him again!" Tenya growled.

"How are you even alive?" Green Arrow asked.

"He's with us." I.Batman said.

"He's on our side." I.Momo assured.

"Unlike your Luthor, I've never indulged in law-breaking. Superman doesn't suspect his best friend is funding the Insurgency."

I.Lex Luthor sits down with them.

"Luthor's involvement is a secret. People critical of Superman disappear. Government officials, activists, reporters..." I.Batman explained.

"Well now that we're all here, explain why you chose us." Wonder Woman said.

"Yeah. Why are we here?" Fumikage asked.

"And why you didn't ask before yankin' us over. We were kinda busy." Green Arrow said.

"The nuclear bomb? It didn't go off. Your transfer somehow prevented it." I.Lex Luthor said.

"How did you know about that--"

"We've been monitoring your world for some time. You four specifically along with some students of yours."

"I have a weapon... To take down Superman. A Kryptonite-based laser that--" I.Batman said.

The prime heroes were shock about this.

"Hold on... A Kryptonite weapon? You kill him, you're no better than he is." Green Lantern said.

"I didn't say 'kill'. It'll incapacitate him. Nothing more. The weapon's in the Batcave. I need your DNA to unlock it."

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

Meanwhile in the Fortress of Solitude, Regime Doomsday is standing at the side while Regime Superman is checking the monitors, prompting he's working something on Doomsday. Just then Regime Wonder Woman enters into the room, not with her usual battle armor but a sexy black strapless shirt and red long skirt.

"The collar's working. Good. Re-educating wasn't going to affect him."

R.Superman nods.

"Mm."

R.Wonder Woman tries to flirt with him.

"You sure you don't want me to stay?"

The room was silence for a moment.

"Kal... I know you didn't lose your super-hearing...Are you okay with this? With us?"

"Of course."

"I'm not trying to replace her. I just thought we--"

"I know. Go on."

R.Superman stands up and comforts her.

"I'm fine."

"I'm going. I just come in to tell you Lantern's--"

"... on his way in. Guess my super-hearing is working."

Regime Diana was not amused with his answer as he leaves; enters Yellow Lantern.

"High Councilor. Love Diana's new look."

Regime Superman just nods in silence.

"We have a problem. I ran into Diana's twin. And someone who looked a lot like Oliver Queen. And Hal Jordan. Along with Fumikage Tokoyami."

This catches the High Councilor's attention as his expression changes.

"Find them. And any others that might be out there. I want to know everything."
