"Ok this next universe is very disturbing. So now I'm gonna send the kiddies over to the kiddie room" said Luke snapping his fingers.

"What's it about?" asked All Might.

"You're just gonna have to see" said Luke as he pulled out his remote and pressed a button.

It began with the remains of the UA entrance. That was all that remained of the building, just the dented logo of the school, and a little bit of the front gate.

"What happened to UA?" asked Nezu in concern.

"Keep watching" said Luke.

The camera zoomed out to show that it wasn't just UA that had been destroyed... it was all of Musutafu. The whole city had been obliterated.

"WHAT HAPPENED?!" screamed everyone.

"Keep watching" said Luke again.

It then showed a news report of what happened. It showed a picture of the remains of Musutafu, and it said: 'MUSUTAFU DESTROYED - MILLIONS DEAD'

"Oh my god..." said Momo putting her hands over her mouth.

"What sick bastard would do this?!" said Iida.

"Keep friggin' watching" said Luke.

It then showed people all over the world, watching the news in horror. Then it cut to outside a heavily guarded interrogation room, where we hear a psychotic laughter inside. It then showed that the laughter belonged to none other than an older Shigaraki, who was being interrogated by an adult Iida.

"You have a freaky laugh, dude" said Dabi.

"No I don't!" said Shigaraki.

Iida slammed his hands down on the table in front of Shigaraki. "The nuke! Where'd you get it?!" demanded Iida.

"So it was Shigaraki who killed all those people!" said Mina.

"You bastard!" said Kaminari.

"Hey at least this version of me managed to succeed against you brats" said Shigaraki.

"What, you want one? Pff. Copycat" said Shigaraki.

Iida screamed in rage, and grabbed Shigaraki and lifted him in the air, when suddenly the wall burst open and in came an adult Izuku, who was wearing a cape and was now flying.

"Holy crap, Midoriya can fly now?!" said Kirishima.

'It seems he's managed to master Nana's quirk' said All Might in his head.

Izuku had a look of pure rage on his face, and his eyes were glowing green for a moment. "Get away from him!" Izuku said to Iida.

"I'm handling this" said Iida.

Izuku walked over to Shigaraki, then threw the table out of the way. He then grabbed Shigaraki and slammed him into the interrogation room mirror.

"You drugged me! Made me...!" Izuku then put his head down.

"Ochako... Eri... my son..." he said.

"What is he taking about?" asked Momo.

"Well you see. It wasn't exactly Shigaraki who destroyed Musutafu... it was technically Izuku" said Luke.

"WHAT?!?!" said the audience in horror.

"Yeah. You see in this universe, Izuku and Ochako were married and Ochako was pregnant with Toshi. But then Shigaraki drugged Izuku and made him hallucinate, thinking that Ochako was Muscular. When the drug wore off, Izuku realized that it wasn't Muscular he had brutally beaten up, it was his wife... and he had killed her along with their baby. And to make things worse, Shigaraki linked Ochako's heart to the nuclear bomb in Musutafu. So when her heart stopped beating, it triggered the bomb and killed everyone in Musutafu, including Eri, since she was there in the city at UA as a student there. So Izuku lost his wife, AND both his children that day" explained Luke.

"Dear god no..." said All Might.

"YOU FUCKING BASTARD!!!!!" screamed Izuku as he lunged at Shigaraki and started choking him, while the others had to pull him away.

"Deku, it's ok! I'm right here!" said Ochako as she hugged Izuku, calming him down.

"People you love tend to blow up? Don't they?" Shigaraki mocked.

Izuku pulled his fist back. "Deku, don't!" said Iida.

Izuku then punched his fist next to Shigaraki's head.

Shigaraki put his hand on Izuku's shoulder. "Heh. That's why I like you, Deku. You're much more gullible than..." he then turned his head to Iida.

Izuku then threw Shigaraki into the table on the other side of the room.

Shigaraki slowly got up. "You think you can have a family. That locking me up will magically reform me. And they'll be safe" said Shigaraki as he walked over to his chair, put it back up, and sat back down in it.

"So big, so dumb" said Shigaraki before laughing some more.

This just made Izuku more angry.

"Now run along so I can break out of here. I've got lots of planning to do to top this!" said Shigaraki.

Izuku then grabbed Shigaraki by the throat with his right arm and lifted him into the air.

"That's enough!" said Iida as he tried to stop Izuku, but Izuku just grabbed him and threw him back.

"I know it's soon, but... Think you'll ever love again? Maybe you won't kill your next family..." Shigaraki mocked.

"Jesus, Tomura. I know I'm training you to be the world's most evil villain and all, but even that's a little too messed up" said All For One.

Izuku finally snapped. He powered up One For All in his left arm and was about to punch Shigaraki through the chest, but right before we could see Izuku's fist go through him, the screen cut to black while the audience heard Shigaraki's laughter... and then his screams.

"Did I just die?" asked Shigaraki.

"We literally just heard you screaming. He punched his whole arm through your chest and out your back" said Luke.

The screen stayed black.

"After that, Izuku decided to make sure something as horrible as Musutafu never happened again, so he started up an evil, world government called the Regime. They ruled the world and killed anyone who stood in their way. As for Iida, he had formed a group of resistance fighters called the Insurgency to combat Izuku and his forces. Some of you guys joined Izuku, some of you joined Iida, and some of you are dead because you were in Musutafu when it blew up, or because Izuku killed you for defying him" explained Luke.

"Do we ever stop him?" asked Iida.

"Eventually. After 5 years you managed to summon an alternate version of you guys from another universe to fight Izuku and the Regime, but that's a story for another day" said Luke.

"I hope this universe serves as a lesson to you all. Killing is always a last resort, even if a villain kills someone close to you. Because if you kill them then you're no better than they are. Understood?" said Nezu to the students.

"Yes, sir!" said the UA students.

I haven't played the first Injustice game (besides the app and the arcade machine) but I have seen gameplays of it, and I have played Injustice 2. Anyways, thx for reading.
