Yes, hello! I hope you guys like this crossover chapter! These are gonna happen because the MHA universe is unique with its potential, to me. So.. ye! Alsoooo since this is a crossover I'm gonna have it be from the POV of the guy in said crossover. Why? I don't know. It just kinda wrote itself out like that? Yeah, that's it.

AStupidMidge: Timey wimey wibbly wobbly, the timeline is shaped like a spaghetti noodle now.

LONG LIVE THE DEKU PROTECTION SQUAD

There are many things you can do. You can walk down the street, make a friend, or, in Barry Allen's case? End up in a completely separate omniverse entirely. He recognized almost nothing. If he knew his geography well enough (which he did, he's run around the world enough to check) he was in Japan. Maybe this Earth's rotation was off? He didn't know. Which was a good sign! It meant he finally discovered a new Earth.

Something else he can do is be tied up like a mummy and dragged over to a homeless man with a glare. Barry had faced many things before, but this took him so off guard he began laughing, confusing the man as his hair began to float upwards. He vibrated himself through the scarf, and judging by the man's surprised expression, he hadn't been expecting this. Well, might as well get this out of the way, and see if his japanese was as good as he hoped it was.

"Uh, which Earth is this?" Great job Barry, good start. The man blinked, before furrowing his brows. "What do you mean which Earth is this?"

Oh. This Earth didn't know? Well that explained a thing or two. How to break this gently? Barry thought for a moment, before pointing a finger at him.

"Okay, what do you know of the Multiverse?"

Why did it have to be him?

Aizawa hadn't wanted his day to end with an explanation that the Multiverse existed. Or that it had been rebooted. Apparently. The apparent lack of a quirk, but with superpowers only served to confuse him more.And that was why he brought the Flash to the only man who could prove if he was lying or not. Detective Naomasa Tsukauchi. So imagine Aizawa's surprise when Tsukauchi informed him that everything he had said was a truth.

"That— That-"

"Means a lot? Yeah, I get that, but Flash here isn't lying." Tsukauchi interrupted, understanding just how Aizawa felt. To be told that a Multiverse did exist? And that most of the "Earths" were so different from theirs was giving the detective a headache. He bet that Aizawa wasn't doing too well either. And then there was the question of… what to do with him? Were they supposed to let him go? Would he stay for a bit to explore their Earth?

He rubbed his temples, his brow furrowing as his headache only getting worse. Aizawa sighed, his head falling onto the table in front of them, to which the Flash raised an eyebrow. He looked at the Detective, who just sighed and shook his head. Today was going to be a LONG day.

Izuku Midoriya had just gotten home from a bad day at school when Aizawa told him about his day. To say the little green haired child was unable to be deterred from meeting this hero from another universe entirely was an understatement. Aizawa swore not even All Might, or this Superman that the Flash talks about, could have kept him off his war path. Of course, apparently Midoriya had heard of the Flash. Aizawa would later find that it was an old comic from the pre-quirk world. Of course he did. He heard of active heroes that even Aizawa didn't know about.

Anyways, when Aizawa opened the door to the room the Flash was borrowing for the time being, exasperated and apologizing for this fresh hell he has wrought upon this hero. Midoriya bust through, and the Flash's eyes widened, knowing a super-fan when he sees one. This could actually be really good, seeing as he is trying to explore the Earths and all.

"Whoa, it's true! You're here! Is it true that you can run faster than light? Could you beat All Might? Is Superman real?! Can Superman beat All Might?! Is there other worlds like ours? Are we unique? Wait, if you're here does that mean that other fixtures heroes are real?" Flash blinked as he watched this six year old rattle off questions almost as fast as him. He then smiled, and began to rapidly answer back. The young boy's eyes lit up, Flash apparently being the only one to understand him. Aizawa watched in horror and amazement as the two talked at incomprehensible speeds, the only thing matching was the speed at which Midoriya made his newest entry in his notebook. After a few minutes, Midoriya asked a question that caught both heroes off-guard.

"Do you think I can be a hero, even without powers?"

…

The Flash gave a gentle smile, his blue eyes glowing slightly. "Yeah, kid. I do."

The Flash was surprised when he saw the kid burst with tears, and even more surprised when he was informed that, no, the tears were not the result of a quirk. Aizawa, on the other hand, gave an approving nod towarss the hero in red. Maybe he wasn't too bad afterall.

Barry was moving to leave Aizawa's apartment when the man grabbed him by the shoulder, and forcibly turned Barry towards him. His tired eyes squinted, as if mentally communicating with Barry.

"Come with me." Was all the raven haired man said before he led Barry into a dark room with candles lit and three figures standing there, wearing cloaks. One was clearly a woman, Aizawa's wife if he had to guess. The other two were smaller.. kids perhaps. Barry could only blinked as Aizawa came into view.

"Let's talk about the DPS initiative."

Two weeks later, the fastest man alive got his suit on, and put on his backpack, making sure the stuff he had wouldn't rattle around too much. Izuku had written down the important stuff, like history and who the strongest heroes were for him. That kid was adorable, and there was no way he wasn't going to tell the Justice League when he got back home. Or Justice Incarnate. Why not both? Both is good.

He straightened his back and looked towards the friends he had made. Small in number and radically different from each other, but they somehow worked together. It made him smile. Izuku shoved himself out of the group, looking at Barry with the brilliant green eyes of his. "Goodbye! It was amazing to meet you, Flash!" He looked like the happiest kid in the world. He deserved it. He got into a running stance, still looking at the kid.

"Good bye, Izuku! I'll visit when I can. Make me proud!" Barry called out, to which the small boy gave a determined nod. Barry laughed softly, before turning to face down the street, and taking off with a sonic boom. Midoriya watched in awe with his hair blowing back as the hero disappeared from view. He turned to his best friend.

"Isn't this awesome, Kacchan? We met the Flash! The Flash is real!"

"Tch. He's not as cool as All Might, Deku." The ashy blonde said, turning to glare at Midoriya.

"Oh, come on, Bakugo. It was still pretty cool," Touya intervened, to which the youngest Bakugo looked away, suppressing a smile. Aizawa felt relieved. Immensely so. Finally.. the headache was over. Ms. Joke was content leaning into her husband. Inko was just watching over her boys and Bakugo. After a small time of just standing there, the group finally left for their respective apartments. When Midoriya got to his room, he looked at the entry in his hero journal, and smiled brightly at the signature in the middle of the page, right next to the sketch of him. Midoriya had good dreams that night.

Hey! Sorry for the wait. I encountered writer's block and tbh it screwed with everything I had going. I still need to update God Mode. But we're not here for that, we're here for Green Bean. I hope you guys liked it! I got inspired to actually try my best to complete this after reading the first issue of Infinite Frontier, which, imo, is really good. Anyways, thank you all who read this, and let me know what you wanna see next chapter? Another crossover? An early introduction? A hero encounter?

Anyways, have a great day, guys! Plus Ultra!

p.s. Sorry for the wait, again!
