Prompt: A good prompt idea would be to have cannon deku switched with this one due to a quirk and see how everyone deals with a different deku (and how fed up everyone in cannon gets with Izu)
I'm counting this as a prompt request because someone else said it to.
hhh was the first person to said it, and then the person who said this was JuniperrBerries (flyingtacorage) on AO3.
I planned to do this eventually, but now I have an excuse to do it!

"Sir, we need to contain Miss. Universe before she injures any more people!" I tell one of the heroes as I helping civilians get out of the rubble. Unfortunately, the hero I am trying to convince fight her is helping civilians as well when he is a combat hero.

"These civilians are of higher priority!" He exclaims. Damn righteous heroes.

"Well, there is certainly going to be more if we don't stop her!"

"Why don't you fight her?!"

"Because I'm more effective at rescue while you are more effective at combat! However, since you aren't willing to do that, I will! Patchy, continue rescue operations!" I exclaim as I zoom off in the CAT armor. I easily find Miss. Universe as she is running on foot, and I throw my grappling hook to grab the back of her shirt. I pull her towards me; however, I notice her spinning around to face me. I release the hook to grab the front of her shirt when she is close, but she reaches towards me, where she ends up touching my arm.

My vision goes black. My hearing goes fuzzy. It feels like I am falling.

Is this her quirk?

Suddenly, my senses return to me harshly when I hear a large boom along with a scream, "DEKU! WHAT THE HELL?!"

What the fuck is Kacchan doing here?

"Patchy is no longer connected. The connection has been moved to Shouta Aizawa."

CAT echoes to me through the visor. What the fuck? It takes going to hell and back to lose that signal, so what the fuck is going on?

I scan my area to realize that I am in one of UA's training facilities.

WAIT, THERE ISN'T AN ATTACK ON UA, IS THERE?!

I start hearing a flurry of booms approaching me, "YOU'RE NOT DEKU! DIE!"

Did I outgrow my name or something? That's not Kacchan.

I see Kacchan appear in front of me, and, on instinct, I grab his arm despite the explosions and throw him against the wall hard. I ain't pulling no sympathy card.

Yagi's voice fills the room, "Everyone, please leave the area. There is a villain in the building!"

Villain? I know I look like one, but come on! You should recognize me...

Wait...we don't have any information on Miss. Universe. What if her name is a dead give-away? She did reach to touch me, so she did activate her quirk.

DON'T FUCKING TELL ME THAT SHE CAN MOVE PEOPLE IN OTHER UNIVERSES!

God damn it God. Fucking the fuckity you.

I hear a familiar snap, causing me to move to the right to avoid that scarf I know too well.

"Hold up, don't attack! I may have attacked him, but that's only because he attacked me!" I raise my hands and look at Shouta, and my theory is confirmed when I see he's wearing that old torn-up thing he calls a costume. He would never switch to that shit again if he didn't have to. He uses his quirk on me but holds a confused look when it doesn't work.

"Who are you?" Sho- fuck that, Aizawa asks.

"Izuku Midoriya at your service, and I am quirkless before you ask! Question: What the fuck is currently happening?" However, I don't know why he is confused. Do I have a quirk here? If so, I will forever be salty.

"We will discuss that in the Principal's office."

"Wait, is Nezu the principal here?" If so, that makes my life soooooooooo much easier.

"Yes." The next thing I know, I am wrapped up in Aizawa's scarf and being dragged to Nezu's office.

"Out of curiosity, what's your relationship with Midoriya?" I don't even get a response to that.

---

"So what you are telling me is that you are from a different universe and that our Midoriya has been switched with you?" Nezu asks with curiosity.

"Yip yip! Here's proof!" I pull out my public hero license and slide it across the counter. Nezu picks it up and looks at it.

"You got Midoriya in your universe?"

"Publically, yeah. I'm above and underground, so I have that for publicity sake, and another one for underground."

"Why are you a public hero when it seems that you want to be an underground hero?" Glad to know he is still smart here.

"I am a quirkless activist, so I am trying to prove that quirkless are as good as those with quirks."

"And you have a detective license as well?"

"Yip yip! I also was your personal student, but I got bored. Now, I am a teacher assistant." Nezu's curiosity seems to peek.

"When our Midoriya comes back, I would like to test his intelligence."

"As long as he doesn't fuck up my shitty reputation, I don't care." Everyone looks at me with surprise when I curse.

"I deny he will. Where were you when it happened?"

"I was in the middle of town when I got switched over. I'm hoping the police aren't stupid and realize what happened, and I don't know how long as we didn't even know the quirk. They should take him to UA to my Nezu and Aizawa. Aizawa will probably look over him as we are close in our universe.

That seems to pique Nezu's interest, "How close?"

"We are on a given name basis, and we take care of each other and all that jazz. Wait, there's an easier way of saying it. Brother basis!"

"That's interesting. Aizawa, you are in charge of Izuku."

Aizawa sighs, "Fine. Come on, brat." He doesn't bother to wait when he leaves, and I run after with CAT rolling behind me.

"That's what my Aizawa calls me sometimes!"

---

"Hold up: your Midoriya is close-combat?" I ask class 1-A. I got bored of Aizawa, and the man expected me to sit there so I left.

"Yeah, he's one of the strongest in our class! Why?" Ashido asks. Yeah, she is still as much of a stalker as she is in my universe.

"We really should not be talking about Midoriya like that!" Iida attempts to interfere, but he still sucks here.

I tap my chin, "I'm intelligence, so I focus on collecting information and fucking people over."

"LANGUAGE!"

"Shut the fuck up, Iida!"

"Do you have no respect for anyone around you?!"

"I don't respect myself, and you expect me to respect others? That's the biggest joke since Trump came into the office!"

"AIZAWA-SENSEI!" Iida screams as he goes fetch the man.

Ashido decides to keep her questions going, "Who are you closest with here in your universe?!"

"Uraraka, though I get along with most of my classmates well. However, I stay mostly with the teachers," I say as I consider my circumstance.

"Ooo, what are they like?!"

"Well, I can tell you that one of them is gay!"

"WHO?!"

"Figure that shit out yourself!"

Kaminari attempts to guess, "Present Mic?"

"I mean, you aren't wrong. You just aren't exactly right."

"OH DAMN!"

Before we can continue, Iida and Aizawa come back in, "I don't know how you snuck past me, but come on."

"Damn it. Well, bye ya'll!"

---

"Sho, can we keep him?! I want a squad!" Yamada asks as I explain to him the squad.

"No. Watch him because I need a nap," Aizawa states as he leaves the room. Yamada gives me a wide grin.

"Mario Kart?"

I smirk, "Wrong game to challenge me at, but alright!"

---

"Brat, how the hell are you awake?"

"I don't sleep!"

"Do I need Midnight to use her quirk on you?"

"I am resistant because they used it so many times on me!"

"Just shut up and let me sleep."

"No."

"Brat."

"Asshole."

"You should improve your language."

"Fuck no."

Aizawa growls at that and leaves the room.

Alright then.

---

"I LOVE YOU, BABY!

AND IF IT'S QUITE ALRIGHT, I NEED YOU, BABY!

TO KEEP ME WARM AT NIGHT!

I LOVE YOU, BABY!

TRUST IN ME WHEN I SAY-OW, LET ME GO!"

"Brat, it's six in the morning."

"It's time to wake up! Waking up early leads to a good day!"

"Whoever taught you that needs help."

"If it makes you feel any better, I made breakfast."

"It better be the best breakfast; otherwise, I am sending you to another teacher."

"OOOO, SEND ME TO MAIJIMA!"

"Maijima? Oh, Power-Loader...no. That's asking for trouble."

I mean, at least he enjoyed breakfast.

---

"My-"

"Don't even start."

"Damn Aizawa. Rude."

---

It's about to be the time I arrive, and I assume that it's a twenty-four hour period. We are waiting for the time to go by.

"I would just like to say thank you for dealing with my shit, Aizawa!" I exclaim with my best smile.

He looks so done with my shit.

"I don't know how your Aizawa does it."

"He gets food and I hooked his gay ass up."

Suddenly my senses go out.

A moment later, and I am in front of presumably Shouta.

"Kid? Is that you?" He asks.

"Yip yip!" Suddenly, I am forced into a tight hug, "MAYDAY MAYDAY!" Obviously, I am ignored.

"Never leave me with that Izuku again. He was the opposite of you. I can't believe I am saying this, but I need your obnoxious self."

"BLESS! Did you not appreciate the break from me?"

"I kept expecting him to do something, but he always followed me. Also, he has a quirk."

"ARE YOU FUCKING KIDDING ME? PLEASE TELL ME IT IS AT LEAST TRASH!" Shouta has to push me away because I am so loud.

"He couldn't use the full power of his quirk, but what he can use gives him immense super strength." Wait...

HE ACCEPTED ALL MIGHT'S QUIRK?! WHAT A PUSSY!

"Alright then."

"I am surprised you aren't screaming."

"Because he's weak."

"I am not going to question it."
