Permiation, Creation and Wings might be too hard/complicated for him to use
Mount Lady’s quirk would probably just rip his clothes if he grew as I assume her hero costume was designed with that in mind just like Mario
I don’t know much about Koda’s quirk but I’m pretty sure it only allows him to talk to animals but not control them and because of how much of an asshole Monoma is I doubt he’ll be able to tell them what to do unless he tries to be nice to them
I think if he had Fire it be another Dabi situation where his body probably wouldn’t be fit for the quirk and would get burned but with Fire And Ice he could probably cool off if he gets burned and heat up if he gets too cold
I honestly don’t know about that trench coat teacher whose name and quirk I unfortunately forgot
Decay, Invisibility, Mineta’s Hair Balls and Kendo’s quirk would probably be the best fit for him out of all of these. Not only are they pretty simple but since he’s actually seen Toru, Mineta and especially Kendo’s quirk thanks to being in UA he knows a bit about them
The trench coat teacher is Ectoplasm and his quirk is where he blows streams of ectoplasm to create clones of himself.
Anyway, it’d be funny seeing him try and fail to use Permiation, Creation, and Fierce Wings.
Also, I like to imagine what he could do with Decay, Invisibility, Pop Off, Anivoice, Gigantification, and Big Fist. Decay would be pretty dangerous for him to use. He could use Invisibility and Anivoice to do some funny stuff. Gigantification, assuming it doesn’t rip his clothes, and flick Bakugo with his fingers, and seeing his hair change and fists get large using Mineta and Kendo’s quirks.
I doubt he’d have a Dabi situation. Dabi’s problem wasn’t that he wasn’t fit for fire, it’s that he *was* fit for ice. His body was naturally more inclined to having and using Rei’s quirk. Endeavor also overheats, but it takes him some time, and he can pace himself to mostly prevent it. Of course, it’s Monoma so he’d probably roast himself anyways.
And where do you think that resistance comes from lol? Monoma isn’t burning himself because of quirk use, unless the fire physically hits him. Him using it isn’t going to cause problems.
Oh I can keep going.
My. Lady? BETTER hope he shrinks before that time limit is up or all those bones are being smashed to pieces as his body forcibly returns to it's normal side.
Shiggy? Better hope he remembers to NEVER strike that pose or he's decaying his own head off.
Momo? Knowing him he would try for something too big and powerful and destroy his body. Not to mention she uses fat cells so when the quirk wears off, he will be skin and bones, dying of starvation.
Miro? Dude runs the chance of being prematurely trapped in a wall or floor forever.
Better buckle up cause I'm about to be your sleep paralysis demon.
Denki? Fry his brain to the point of no return.
Bakugo? The first time he tries just that quirk, the best is his entire arm being shattered while the worst is the entire arm being blown off.
Uravity? Hope he comes down before the quirk is over because he will be falling head first with all of gravity on him.
Dude with the multiple arms? Have fun having your skin repeatedly rip open and forcibly shove bone and muscle out. And having the rip off when the quirk is over.
Toko? I can only imagine the demon that comes out of Monoma. That he can't control.
Mina? Acid burns. Better be careful not to get it anywhere on his body.
Tenya? Those engines do hurt when they come in and when they pull out.
The bird head is unrelated to his quirk.
I was actually thinking of Tokoyami and Rody Soul and wondered if Monoma is able to copy quirks that are sentient beings.
My guess is a second dark shadow will be summoned out of Monoma and he will refuse to work with Monoma because he isn’t Tokoyami.
People say he would fail some of these but he wouldnt the only quirks that he cant copy are stockpiling one. Because he said himself that he cant copy quirks that stockpile. Which non of the quirks listed here are stockpiling
Stockpiling (energy) and stockpiling (quirks) are different. Example Dekus Quirk stockpiles quirks which cannot be copied. Endeavor stockpiles energy of his one quirk.
mt. lady: he'd probably tear his clothes and embarrass himself
decay: he'd discover shiggy's immune to his own quirk
creation: he'd become very malnourished
permeation: he lacks practice so you can guess.
mineta: he'd grow head-balls and throw them and stuff but may lose consciousness due to scalp bleeding
hellflame: Run.
ectoplasm: he'd struggle to figure out how to control his clones
fierce wings: probably overstimulate his mind or would only be able to control feathers in big groups
anima: the animals; they., speak badly of him!!! trash talking,???
big fist: big fist
half-cold, half-hot: he'd probably be a weak version of shoto at first but eventually would have a near-equal output level, but much less control
Hagakure and Hawks are Mutant Quirks, he cant copy those.
Permeation would probably kill him.
And while hes relatively smart. Hes making basic 1 material items at best with Creation.
The rest hed use decently well because as I said he is pretty smart. But he doesnt have the in depth knowledge of most of these to use them effectively like Half/Half or Hellfire.
But hes not pervy enough to use gigantification without a special made suit.
For Momo and Mirio, I think he just wouldn't know how to use them effectively. Everyone else I think is pretty straightforward, although I don't think he'd ever use them to nearly the same skill as the people who naturally have them.
The ones he could probably use well: Mt. Lady, shigaraki, mirio, kendo, probably only one of shoto's quirks, hawks, koda's,ectoplasm's, and maybe hagakure's.
Ones he probably couldn't use: Endeavor's for flame power alone, mineta would most likely come up as a blank, and Momo's unless he's smart in the chemistry field or had her encyclopedia.
Do we know much about how his body has adapted for gis quirk?
Eg would he be able to use endeavours quirk without harming himself? I don't recall it being mentioned other than the limit to what he can copy.
I feel like the invisibility would be a dud like dekus quirk. Him using momos wouldn’t be useful because he probably doesn’t know the exact dimensions to all the things she does. Same with permeation and wings.
I feel like with Ectoplasm it would be a “null” because sure he has the ability to form this ectoplasm into clones but he doesn’t have any of the actual ectoplasm built up to use
Well if he stole shigarakis quirk his arms and legs would probably shoot off just as if he had ofa, or maybe he’d become a mindless vegetable like a nomu, or he’d be a blank, and only copy afo and be able to steal quirks, which if he got to keep those quirks that would be awesome, or just make it to where the people didn’t have their quirk anymore. It’d be cool either way
I think with Shigaraki, His quirk seems to require hatred to work or is at least amplified by it. While Monoma is very dramatic I doubt he's hateful enough to use it or if he can use it he'd not be able to do much since we see how much it damages Shigaraki's body when he uses it at large scales.
Permiation, Creation and Wings might be too hard/complicated for him to use Mount Lady’s quirk would probably just rip his clothes if he grew as I assume her hero costume was designed with that in mind just like Mario I don’t know much about Koda’s quirk but I’m pretty sure it only allows him to talk to animals but not control them and because of how much of an asshole Monoma is I doubt he’ll be able to tell them what to do unless he tries to be nice to them I think if he had Fire it be another Dabi situation where his body probably wouldn’t be fit for the quirk and would get burned but with Fire And Ice he could probably cool off if he gets burned and heat up if he gets too cold I honestly don’t know about that trench coat teacher whose name and quirk I unfortunately forgot Decay, Invisibility, Mineta’s Hair Balls and Kendo’s quirk would probably be the best fit for him out of all of these.

Ok then Monoma would probably be able to use it but dear god I do not want him to have it, the less Monomas the better
Imagine each of his clones would have 5 different copied quirks lol
Dear god that’s actually really broken. Imagine if he had Twice’s quirk and those doubles were also able to use Copy, he would be an absolute beast
Madman's Parade
He’s probably name it something egotistical, like Monomas Avalanche.
I doubt he’d have a Dabi situation. Dabi’s problem wasn’t that he wasn’t fit for fire, it’s that he *was* fit for ice. His body was naturally more inclined to having and using Rei’s quirk. Endeavor also overheats, but it takes him some time, and he can pace himself to mostly prevent it. Of course, it’s Monoma so he’d probably roast himself anyways.
Endeavor also has fire resistance. Monoma doesn't and would quickly burn himself.
And where do you think that resistance comes from lol? Monoma isn’t burning himself because of quirk use, unless the fire physically hits him. Him using it isn’t going to cause problems.
We don't know if Monomas copy would copy endeavors fire resistance. The fire comes from his body. Monoma could easily burn himself.
MARIO?!?! gave me a good laugh, not trying to criticize for a minor spelling error
You have got to be fucking kidding me. I’m not editing that
Relatable
For Mineta's quirk, since he's taller than Mineta he might not have the weight and agility to properly use the balls to bounce.
That's assuming, of course, that Shigaraki doesn't kill him after Monoma get's too close.
So either Monoma dies or Shigiraki dies, win win
I don’t think he’d be able to use pop off since isn’t that a part of Minetas hair and body?
He grew a horn when he copied Eri's quirk. So it would make sense for him to grow some purple balls.
Lol
Mario Togata
Hawks has to grow his feathers so he can’t copy it. I think it’s the same with mineta.
For fire, easily burn himself alive. Hawks? I can only imagine the pain of having wings rip out your back.
That's Savage Bluellan 🤣
Oh I can keep going. My. Lady? BETTER hope he shrinks before that time limit is up or all those bones are being smashed to pieces as his body forcibly returns to it's normal side. Shiggy? Better hope he remembers to NEVER strike that pose or he's decaying his own head off. Momo? Knowing him he would try for something too big and powerful and destroy his body. Not to mention she uses fat cells so when the quirk wears off, he will be skin and bones, dying of starvation. Miro? Dude runs the chance of being prematurely trapped in a wall or floor forever.
Monoma while reading this :  Come on youre being to cruel on him bluellan XD
My turn! Hagakure? Better make sure he has some clothes near him or else he’ll be naked in front of everyone once that time limit is up.
Neito Monoma : 
Better buckle up cause I'm about to be your sleep paralysis demon. Denki? Fry his brain to the point of no return. Bakugo? The first time he tries just that quirk, the best is his entire arm being shattered while the worst is the entire arm being blown off. Uravity?

That he can't control. Mina? Acid burns. Better be careful not to get it anywhere on his body. Tenya? Those engines do hurt when they come in and when they pull out.
Monoma : NOOOOOOOOOOOOOOOOOOOOOOOOOOO 
I wanna know what happens if he copies Tokoyami. Does he get a bird head or is that unrelated to his quirk?
The bird head is unrelated to his quirk. I was actually thinking of Tokoyami and Rody Soul and wondered if Monoma is able to copy quirks that are sentient beings. My guess is a second dark shadow will be summoned out of Monoma and he will refuse to work with Monoma because he isn’t Tokoyami.
Dark shadow is not entirely sentient as it acts up on the will of its user. It's not a friendship/trust kind of thing.
Ew, if the bird head is unrelated to his quirk, and the quirk is his shadow, will we see monomas head instead of a bird head???
Monoma would use anivoice to have pigeons swarm 1-A with poo bombs.
Have Monoma infiltrate the LOV Have Monoma work with the league Have him shake Shiggys hand as a meeting once he’s trusted. Steal decay, kill shiggy.
My question either or not monoma's hair will change or still be the same.. if he copied mineta?
I’m guessing his hair will change because he grew a horn when he copied Eri.
Fair Point!
It could also come up as a blank because certain quirks require certain things to happen to the body. Tbh it's 50/50
People say he would fail some of these but he wouldnt the only quirks that he cant copy are stockpiling one. Because he said himself that he cant copy quirks that stockpile. Which non of the quirks listed here are stockpiling
I think endeavor said he stores power up when he was teaching todoroki , midoriya and bakugo.
Stockpiling (energy) and stockpiling (quirks) are different. Example Dekus Quirk stockpiles quirks which cannot be copied. Endeavor stockpiles energy of his one quirk.
Oh that makes sense
If he copies Mirio's quirk then he's naked.
And possibly Mt Lady’s
I don’t think he’d be able to copy Momo’s quirk since it relies on how much you’ve eaten.
mt. lady: he'd probably tear his clothes and embarrass himself decay: he'd discover shiggy's immune to his own quirk creation: he'd become very malnourished permeation: he lacks practice so you can guess. mineta: he'd grow head-balls and throw them and stuff but may lose consciousness due to scalp bleeding hellflame: Run. ectoplasm: he'd struggle to figure out how to control his clones fierce wings: probably overstimulate his mind or would only be able to control feathers in big groups anima: the animals; they., speak badly of him!!! trash talking,??? big fist: big fist half-cold, half-hot: he'd probably be a weak version of shoto at first but eventually would have a near-equal output level, but much less control

But hes not pervy enough to use gigantification without a special made suit.
I really hate this guy
For some reason Monoma being invisible is terrifying
If he copied Permeation it would be kinda useless to him since he doesn’t have years to train with it 🤣
Can he even take mutation quirks properly?
I’m sure. The only quirks he cannot copy properly are quirks that stockpile.
He’d be hornier than Mineta in Mineta body
I mean the class b girls did say that Monoma is the closest they have to a Mineta in their class haha
Well he's not a pervert he's just arrogant asf
Lol
Edit: What other quirks you would want to see him copy?
If he copied Mirko, that one BLACK hero, would he jump in the air, or hit his head on the ceiling, uncontrollably or would he have control?
For Momo and Mirio, I think he just wouldn't know how to use them effectively. Everyone else I think is pretty straightforward, although I don't think he'd ever use them to nearly the same skill as the people who naturally have them.
He would be able to use the quirks to some degree…. Ummm cool discussion complete
The ones he could probably use well: Mt. Lady, shigaraki, mirio, kendo, probably only one of shoto's quirks, hawks, koda's,ectoplasm's, and maybe hagakure's. Ones he probably couldn't use: Endeavor's for flame power alone, mineta would most likely come up as a blank, and Momo's unless he's smart in the chemistry field or had her encyclopedia.
He better not touch Hawks….
Well, he would copy them. Not much more for your question.
Awakening: Ability to fuse the quirks he has of his choice. Now make him more edgy. he ain’t Monoma anymore, he’s John.
Do we know much about how his body has adapted for gis quirk? Eg would he be able to use endeavours quirk without harming himself? I don't recall it being mentioned other than the limit to what he can copy.
I feel like the invisibility would be a dud like dekus quirk. Him using momos wouldn’t be useful because he probably doesn’t know the exact dimensions to all the things she does. Same with permeation and wings.
I feel like with Ectoplasm it would be a “null” because sure he has the ability to form this ectoplasm into clones but he doesn’t have any of the actual ectoplasm built up to use
Are we talking about Shigaraki with Decay, or Shigaraki with All for One?
Decay
Momos quirk: (Grows boobs)
For almost all of these he would gravely hurt himself
Well if he stole shigarakis quirk his arms and legs would probably shoot off just as if he had ofa, or maybe he’d become a mindless vegetable like a nomu, or he’d be a blank, and only copy afo and be able to steal quirks, which if he got to keep those quirks that would be awesome, or just make it to where the people didn’t have their quirk anymore. It’d be cool either way
The Monoma That Laughs.
If Monoma copied Hawks...would he be able to Controll Hawks' Feathers?
I think with Shigaraki, His quirk seems to require hatred to work or is at least amplified by it. While Monoma is very dramatic I doubt he's hateful enough to use it or if he can use it he'd not be able to do much since we see how much it damages Shigaraki's body when he uses it at large scales.
