Luke came out of a portal dressed as a Ghostbuster.

"Luke, why are you wearing that?" asked Izuku.

"Because it's Halloween in my universe, so I'm gonna show you guys a very scary universe. But it's too scary for the kids, so I'm gonna send them to the kids room now" said Luke as he snapped his fingers.

"What's the universe?" asked Ochako.

"It's a surprise" said Luke before pressing a button on his remote.

It began with the city of Musutafu one day. The streets were empty, with nothing but abandoned cars in the streets. But then it showed Bakugo, Kirishima, Iida, Tetsutetsu, Mineta, Kendo, Awase, and Setsuna running from something. The students were wearing their hero costumes, but they had armor and weapons strapped over them, as well as backpacks. Setsuna was also missing her left arm.

"What's with the post apocalypse us?" asked Tetsutetsu.

"Keep watching" said Luke.

"And why am I missing an arm? Am I using my quirk right now or something?" asked Setsuna.

"I said keep watching" said Luke.

They then went inside an abandoned building, and barricaded the door.

"You think that'll hold?" asked Kendo.

"Hopefully" said Iida.

But then the door burst open, and it showed Izuku, Ochako, and Todoroki standing there in the doorway, but they were standing in the shadows so they couldn't see their faces. They could see a bit of Izuku's arm, because he had just used One For All to punch the door open, so there was some green lightning around his arm, but his skin looked a bit green.

They then stepped into the light, and the audience saw that the three of them... were zombies.

"What the hell happened to us?!" said Ochako.

"The Earth of this universe is known as Earth Z. It's a zombie universe" said Luke.

"Zombie's are real?!" said Kaminari.

"They are on Earth Z. Basically, in this universe a mysterious zombie virus spread. No one knows where it originated from, but in less than 24 hours, it spread across the planet. And now Izuku, Ochako, Todoroki, the rest of Class 1-A and 1-B, and almost everyone else in the world are zombies" said Luke.

Zombie Izuku lunged at them, but Bakugo blasted him into a wall with an explosion. Zombie Ochako then fired a rope out of her gauntlet and tried to tie Kendo up with it, but Kendo just grabbed the rope, and threw Ochako into another wall. Then Zombie Todoroki fired a blast of fire at Kirishima and Tetsutetsu, but they activated their quirks, charged at Todoroki, and started punching him repeatedly. Todoroki tried to bite them both, but he couldn't get through their skin since it was too hard.

"The reason Kirishima and Tetsutetsu haven't been infected yet is because a zombie needs to bite through their skin to infect them. But Kirishima and Tetsutetsu can just harden their skin so the zombies' teeth can't get through it" explained Luke.

"How have the rest of them not gotten infected yet?" asked Aizawa.

"Pure luck, I guess. Bakugo's the leader of the last remnants of humans in Japan. Him, Iida, Mineta, Kendo, and Awase were able to avoid getting bitten by the zombies" said Luke.

"What about me?" asked Setsuna.

"You were sort of bitten. At the start of the zombie apocalypse, you detached some of your body parts to fight the zombies, but your left arm got bitten and turned into a zombie arm, but it didn't affect the rest of you because it wasn't attached to you. So now you're missing an arm" explained Luke.

"We need to get out of here!" screamed Mineta.

"I got an idea!" said Bakugo.

He then blasted a hole through the wall.

"Mineta, keep them in place!" said Bakugo.

Mineta pulled a bunch of balls off his head and through them at the zombies to keep them in place, but it wasn't gonna hold them for long.

They rushed out of the building and onto the streets. But when they got outside they saw the rest of Zombie 1-A, Zombie 1-B, and their teachers as zombies standing there.

Zombie Sero fired not tape, but his own own guts and organs out of his elbow.

"WHAT THE HELL?!?!" screamed Sero.

"Another thing I should mention. The zombie virus affected the quirks of some of you. So instead of firing tape out of your arm, Sero, you fire your own organs" Luke explained.

Sero then wrapped Awase up with his organs, and pulled him over to him and the other zombies.

"AWASE!!!" screamed Tetsutetsu, Kendo, and Setsuna.

"AWASE, NO!!!" screamed Class 1-B.

The zombies then devoured Awase, and the survivors were haunted by his screams.

"Shit! Four-Eyes, do you have any juice left?!" said Bakugo.

"Just enough to get us all out of here!" said Iida.

Bakugo got on Iida's back, Mineta got on his shoulders, and Iida lifted both Kendo and Setsuna.

"Wait! There's no room for Tetsu and Kirishima!" said Kendo.

"It's fine, babe! Me and Kirishima will stay behind and hold them off!" said Tetsutetsu.

"Tetsu, no! We're not leaving anyone behind!" said Kendo.

"We'll be fine! The zombies won't even be able to bite us anyway! We'll meet you back at the hideout! Now go!" said Kirishima.

Iida and the others zoomed away, and soon they were back at their hideout. It was an underground bunker, located under an old building.

When they entered they were greeted by Mei, Shinso, Recovery Girl, Eri, Kota, Katsuma, Mahoro, and some civilian survivors.

"Where's Awase, Kirishima, and Tetsutetsu?" asked Mei.

"Awase didn't make it. And Kirishima and Tetsutetsu stayed behind to hold the zombies off. We don't know if they're gonna be ok or not" said Bakugo.

"Mei, Shinso, Recovery Girl, Eri, Kota, Katsuma, and Mahoro are also survivors. They rescued Mei when Zombie Power Loader was trying to eat her, they rescued Shinso when Zombie Aizawa was trying to eat him, they rescued Recovery Girl when her zombified patients were trying to eat her, they rescued Kota when the Zombie Pussycats were trying to eat him, they rescued Katsuma and Mahoro when they're Zombie dad was trying to eat them, and they rescued Eri when Zombie Izuku and Ochako were trying to eat her" explained Luke.

"We tried to eat our own daughter?!" said Izuku.

"It's not your fault. You weren't in control of yourselves" said Luke.

"Here are the supplies we got" said Iida as they took their backpacks off and pulled out some food, medicine, and other supplies.

"The whole reason they were out there in the first place is because they were looking for food and supplies" said Luke.

"How's the cure been coming along?" Bakugo asked Recovery Girl.

"Not much progress, I'm afraid. Eri's blood has been able to rewind the zombies a little, but not that much" said Recovery Girl.

"What are they talking about?" asked Izuku.

"Eri's blood may be the key to curing the zombie virus. Her blood might be able to reverse the effects if they can turn it into an antidote. Eri agreed to let Recovery Girl take some samples of her blood, even thought it reminded her of the things Overhaul did to her. But so far they haven't had much success with making a cure" said Luke.

They then heard a knock at the door.

"Who is it?" asked Bakugo.

"It's us" they heard Kirishima's voice say.

Mineta opened the door and saw Kirishima and Tetsutetsu standing so perfectly still with blank expressions on their faces.

"You guys ok?" asked Mineta.

But then... the normal Kirishima and Tetsutetsu disappeared. And instead they saw Zombie Kirishima and Tetsutetsu standing there, and they grabbed Mineta and devoured him.

For some reason, most of the audience didn't mind seeing Mineta get eaten.

"How the hell?!" said Bakugo.

Zombie Kirishima and Tetsutetsu entered the room, as well as the rest of Zombie 1-A and 1-B, Zombie Awase... and Zombie Camie.

"CAMIE?!?!" said Bakugo in horror.

They then realized that the Kirishima and Tetsutetsu they saw and heard at first was just an illusion created by Zombie Camie.

"But wait, how did Tetsutetsu and Kirishima get infected? You said the zombies couldn't get through their skin, Luke" said Kendo.

"Well as you know, they can't keep their skin hard forever. Eventually, they ran out of energy and the zombies bit through their skin" explained Luke.

Zombie Tetsutetsu them lunged at Kendo and started eating her.

Tetsutetsu was very disturbed with seeing his alternate zombie counterpart eat the girl he loved.

A hole then burst through the ceiling, and they looked up and saw the Zombie League of Villains at the top. There was Zombie Shigaraki, Zombie Dabi, Zombie Toga, a bunch of Zombie Twices, Zombie Spinner, Zombie Kurogiri... and Zombie All For One.

Zombie Ochako jumped on top of Mei and bit her, and she started turning into a zombie as well.

"Mei, no!" said Iida as he rushed over to his girlfriend and kicked Zombie Ochako away from her. But it was too late, Mei was now also a zombie, and she jumped on top of Iida and started eating him.

Shinso tried to fight the zombies, but they outnumbered him and started eating him as well.

Setsuna was about to fight the zombies, but then her left zombified arm that was once lost emerged from the group of zombies and grabbed her by the neck and started choking her. This distracted her long enough for the zombies to grab her and start eating her, too.

The zombies then ate Recovery Girl and most of the other human survivors, until it was just Bakugo, Eri, Kota, Katsuma, and Mahoro.

"Kids, get behind me!" said Bakugo as he stood in front of the kids to shield them from the undead.

Bakugo blew most of the zombies up, but more kept coming.

They then ran into a room. Bakugo was about to close the door, but then Zombie Izuku bit his arm. He then closed the door all the way and barricaded it.

"Mr. Bakugo, are you ok?!" asked Mahoro.

"All of you stay away from me!" said Bakugo as his skin started to turn green.

"So wait, I'm gonna turn into a zombie and eat the kids?!" said Bakugo.

"Not exactly. Watch this next part" said Luke.

It seemed like all was lost. But then... a portal opened, and out came Luke.

"LUKE?!?!" said the audience in shock.

"I told you all before, some universes I help out in" said Luke.

"Kids, come with me. I'm gonna bring you four somewhere where you'll be safe" said Luke.

"Who are you?" asked Kota.

"Not important. But I'm gonna bring you kids to another universe where there's no zombies" said Luke.

"But what about Uncle Kacchan?" asked Eri.

"I'm already infected, kid! My time's up! Just go with him!" said Bakugo.

"There's no time to argue! Just go through the portal! Quickly!" said Luke.

"KIDS, GO!" said Bakugo as he started to change.

"Goodbye, Mr. Bakugo" said Katsuma and Mahoro with tears in their eyes.

The kids and Luke went through the portal and it closed. When the zombies broke down the door they saw that Bakugo was now a zombie like the rest of them.

The screen then cut to black.

"I brought Eri, Kota, Katsuma, and Mahoro to a zombie-free universe. A universe where they were never born, so they wouldn't have to share it with alternate versions of themselves" said Luke.

"Did you go back and rescue any other survivors?" asked All Might.

"Afraid not. I can't risk the virus spreading to other universes. Me saving the kids that one time was the exception, because I couldn't bare to see those small innocent children get eaten... or worse. Anyways, let me change out of this costume, and then we'll watch the next universe" said Luke.

Thx for reading. And happy Halloween, everyone!
