"I'm telling you, Mementos feels weird." Morgana said as Makoto drove through the paths of the mysterious subways of the human subconscious. "There's a taste in the air…"

"Mind explaining that a bit more?" Ryuji asked, reclining in his seat. "The last time I checked, the air doesn't 'taste' like anything! It's air!"

"Yeah, maybe for you!" Morgana shot back in a huff. "But unlike someone who's lacking in the brains department…"

"Watch it, cat!"

"I'm not a cat!" After the outburst, the cat-bus continued. "Anyways, I've been here for a while! There's something seriously different about the place!"

"In what way? Is it a Shadow?" Izuku asked from his seat. The members of the Phantom Thieves had decided to go further into Mementos to train and let off steam after defeating Madarame's Shadow. Yusuke needed more practice with his own Persona and they needed to find new ways to incorporate its abilities into their strategies.

Morgana hesitated for a second. "Well… I can't say for certain…"

"You don't know, do you?" Ann asked the cat, who let out a soft whine.

"Lady Ann…"

"I don't know about you guys, but it does feel a bit creepier than usual…" Makoto turned to the left of a splitting track.

"Indeed. The aura of Mementos has its voice, and today it's distorted." Yusuke leaned forward from the backseat. "Look at the walls."

Izuku focused his gaze on the walls. The same black, purple, and red coloring was pulsating into the pseudo-concrete… "Wait, no that's not all!" Every now and then, there were cracks that let out beams of multi-colored light. It faded in and out, and every now and then tiny black dots came out.

"Man, what's up with that?" Ryuji pointed at a wall to the right. "Where are the dots comin' from? Is there some sort of bubble machine behind them?"

"I swear I've seen those in a piece of art somewhere…" Yusuke muttered while tapping his paintbrush to his miniature canvas. "Pop art perhaps?"

"Could it be a sign of an enemy?" A powerful Shadow that resided in Mementos' depths? "No. Morgana would've been able to sense it… at least I hope."

It was possible this was something else entirely.

Suddenly, the bus stopped and everyone lurched forward. "Morgana, what the hell!?" Ryuji demanded as he got up, his face red from it slamming on Izuku's headrest.

"Shh!" Morgana opened his doors. "I hear something!"

"A Shadow? Then drive into it man!"

"No, not a Shadow! Something else!"

Izuku focused on the sounds around him. "Okay, the dripping of water or the closest thing to the floor, our breathing and…" Yes, it was distant but he could hear it too! "I-I hear people talking!"

"People? Down here?" Ann's covered her mouth before whispering, "But that's impossible. I thought only we could come here."

"Well, we need to find out what that is somehow." Makoto looked to Izuku. "What do you want to do, Midori?"

They needed to find out what that was, and while it would be sensible to also go around the other way there was the possibility whatever was ahead might just decide to explore and find them. "I say we keep going, but quietly."

They got out of the bus and Morgana returned to his regular form. They walked along the tracks towards the origin of the echoes, and the voices became clearer.

"...place like a maze. I don't like it."

"...Complain? You can fly through… in a minute…!"

"ZEHEHAHAHA! The so called 'perfect'... aftraid of the subways!"

"...need to make a claim to this place…"

"...the fuck do I have to be here for this bullshit!?"

Izuku gulped as they reached a platform with stairs leading down, the arguing coming from the bottom. "Yup, those are definetly people talking." Izuku held his index finger to his mouth and moved to the left side of the doorway with Ryuji and Yusuke while Makoto, Ann, and Morgana went to the right.

With the angle they were looking at, they couldn't see the speakers' full bodies. They simply saw legs, feet, and one case a belly. One pair looked vaguely insect-like with green and black plating and shoes that looked more like plates melded to flesh. Another pair had curled gold shoes that matched the yellow pants, who's green heart-shaped guards clashed with. Another person had stubby legs which revealed a very large brown belly.

Finally, a person was at the bottom of the stairs and had on a much more sensible pair of leather pants and black shoes.

"Fine." A cultured and arrogant voice came from below. "If this area is so important then you can manage it."

The one who was behind the door shifted. "I am only taking it because you all seem too stupid to realize its value."

"ZEHEHAHAHA!" The one with the belly laughed, his girth jiggling from the act. "You've got some serious balls, Mysterio!"

"Watch yourself, whelp." Another voice came, this one deeper. "We may be allies for now, but it will not last. The moment our goals do not align and he's not hanging overhead…"

"The Heroes could hide anywhere in here, and if some of them escape from our little surprise party they will come straight here."

"Are these Villains?!" Izuku asked himself, sweat dribbling from his brow. "Villains found a way into the Metaverse!?" This was bad! Really bad! If Villains found a way into this world, then they can use the rules to their advantage! "They can cause mental breakdowns to commit their crimes! On the Heroes who chase them!" He looked to his teammates to see their equally worried expressions.

"Anyways, I would like to remind you that he trusts me over any of you. After all, who could trust Cell or Dio Brando to…"

"Cell?" Ryuji covered his mouth, but it was too late.

"You idiot!" Ann hissed out, and the feet turned around.

"It seems we've got some eavesdroppers." The cultured voice said aloud as if he were talking about the weather.

"Prowler, kill 'em."

"RUN!" Izuku shouted, turning around and beginning to sprint with the others following him.

"Run!? Come on man, we can take them!" Ryuji reached for his mask but Makoto slapped his hand down.

"We won't have to if we can lose them! Otherwise we're going to have to deal with four other pissed off Villain!"

"Villains!? Come on man, they called each other Cell and Di-OOOH!"

Ryuji let out a scream as a cord wrapped around his midsection and pulled him back. The Phantom Thieves turned to see a purple and green suited female figure pulling the cord, glaring at them and her right hand open on the side. The fingers glowed green, extending and sharpening as she grabbed Ryuji by his collar and bringing his back to her. She kept him in place with a chokehold.

No time to think. "PERSONA!" They shouted, ripping off their masks and summoning the manifestations of their rebellious spirit. "Damn it! We can't attack without hitting Ryuji!"

Izuku's eyes could swear that the Villain's eyes lingered on him for a second before they hardened. "You shouldn't have come here, kids." The Villain, Prowler, said in a distorted voice before bringing her hand down.

"RYUJI!"

"Hey, none of that!" A new voice declared before something whizzed by Izuku's right ear. In a second, a grayish thing that looked vaguely like webbing wrapped itself around Prowler's hand. "Also, no touchin' the cosplayers! You know the rules Prowly!"

"You!?" Prowler shouted, her grip loosening enough for Ryuji to push off her and use his Quirk to burst away.

"Duck!"

The Phantom Thieves complied, during their heads while their Personas moved to the sides.

"KAMEHAMEHA!"

"Wait, what!?"

Izuku looked up to see a beam of white energy pass overhead and slam into Prowler, blasting her back into the shadows of the stairs.

A Villain, one who the others were confident could handle them alone, blown away in an instant.

Izuku turned around and saw something he had a hard time believing.

The ones who rescued them were Heroes that shouldn't, couldn't, exist.

Goku, Ichigo Kurosaki, Yusuke Urameshi, freakin' Naruto!

The most surprising Hero among them was the old comic superhero Spider-Man, but he looked… different.

For one thing, his body was… a different shape. Not as muscular as Izuku remembered.

Oh, and he was wearing sweatpants.

Next to him was someone his age dressed in a cheap Spider-Man costume, but with a pair of exercise shorts and a hoodie over it. The green eyes from behind the cut eyeholes stared at Izuku with wide horror.

"Hiya!" Goku broke the silence, waving at them. "Cool costumes!"

"What is it with kids and leather when it comes to their costumes?" Spider-Man pointed at Makoto. "Also, those spikes can mess someone up if you bump into them."

"Wha… how…!?" Ann began, gaping and pointing at the gathered Heroes.

"HOLY CRAP!" Ryuji shouted. "GOKU'S REAL!?"

"Unfortunately…" Ichigo muttered while Goku chuckled and scratched the back of his head.

"Alright kids, there's a lot to go over and not a lot of it is going to make sense, but that's kinda standard with these multi-dimensional crisis'." Spider-Man then pointed to Izuku. "You're Izuku Midoriya, right?"

"H-Huh!?" How could Spider-Man know his name!? "Y-Yes?"

"Alright, this is weird for everyone here. But for you, personally?" Spider-Man patted the kid next to him on the shoulder, who reached for his mask.

The boy took it off and Izuku gazed at his own face.

"It's going to get a hell of a lot weirder."

Izuku stared at himself, who nervously smiled and waved.

"Two Midori's…?" Makoto mumbled out, her eyes widening.

"Dude…" Ryuji's jaw dropped while Ann's eye twitched.

"I must paint you together when we get the chance." Yusuke added to the conversation helpfully, making a faux-frame with his index fingers and thumbs.

"Uh, Hero?" Morgana nudged him. "You okay?"

It was at this moment that Izuku fainted.

The world of blissful unconsciousness made more sense.

Note: This is just a fun thing I wrote up after talking with MugiwaraN0Luffy, the author of the MHA/Persona 5 crossover Thieves Can Be Heroes, about how the Phantom Thieves would reach to a schlubby Peter Parker. Things just kinda went from there after I wrote those Jump Force snippets.

Thankfully, he loved this snippet.

Make sure you read Thieves Can Be Heroes as soon as possible. It's a great fic that you'll love.

Be sure to leave a review and check out the TV Tropes page of the main fic.
