#so his quirk might just be ‘Socially Accepted Neurodivergent but with benefits’

Gremlin Izuku

Ok so this is a continuation of this post that @lovelyflowerlov and I are working on. It started as a shitpost and now we’re here and living our best lives. I’m making this separate just because the other is getting too long to scroll through. Click the link for context on the AU

—————————-

Before some more Battle Trial stuff (which I will get to later) I thought about what exactly Izuku’s quirk and appearance is.

Quirk

Possible Quirk names: Gremlin, Unhinged, Energize

Because we’re having Izuku be a Gremlin Boi™ and thus have, in the words of flower, “Teeth that are even more sharp than a shark, Amazing Bouncy Skills™, never ending enthusiasm, a night owl, and Bastard™ Energy” I say that his quirk is the ability to inhibit the body’s inborn limiters. You know, the things that make it so you don’t tear your muscles from bones everytime you use them. A common example being how your jaw is strong enough to bite off your finger, but your brain prevents you. Mainly basing this off hysterical strength and this video. Izuku can consciously turn this limiter off, both on himself and others. He could chomp his fingers like carrots if he wanted to. But it’s not just muscle limiters

You know that little voice in your head that tells you not to do or say stuff? The social conventions you know to follow, and thus what to do or say? The things that limit your actions? Ya, Izuku’s quirk prevented him from getting that. Though he does kinda have the opposite of it, explained later. He has to actively think about what he can and can’t do in a situation, and sometimes he just forgets or doesn’t understand that there are unspoken “rules” he needs to follow or behaviors he shouldn’t express. When activated on another person, they no longer feel pressured to act a specific way. His quirk also encourages reckless behavior; acting without care for possible harm to self. Izuku has grown up with this urge so he has learned how to fight it off, and actually has remarkable self control to not do 90% of the stuff his quirk tells him to. Not so much the case for people who have this pushed onto them for the first time. Kinda like Trigger and making people act differentenly :)

Example: during the Entrance Exam when he saw Uraraka trapped under gravel and the 0 pointer coming closer, his first instinct was to destroy the robot. To him, the rubble wasn’t the immediate threat and instead the robot that was walking towards her was. Shinsou was the one to convince him to try getting the debris off her first, and go from there. Only after that failed did Shinsou let Izuku enact his insane plan of eating the 0 pointer’s wires (which Izuku then teased Shinsou with the fact it worked and we should have just done that first, Hitoshi)

Because he can use all his muscles whenever he desires, his body naturally has a higher glucose stockpile than normal people to make up for the fact he will use more ATP working a higher volume of muscles (since muscle contractions use energy and glucose is the first energy storage the body burns through). However, he also needs to burn through that energy or else he risks damaging his nerves because of too much glucose in the blood (reason for nerve damage in diabetic people). Thus, he naturally has a higher energy level than other people so he jumps jumps jumps, has never ending enthusiasm, and always likes to be doing stuff. Tapping his foot, twirling his pencil, humming, analysising and writing in his notebook. This does infact burn his energy; mental fatigue is a thing my dudes. This also makes it so he loves to cause chaos, mischief, create pranks, and generally be a little nuisance, since it requires careful planning and energy running around to set it up, but that’s mainly just him being a little Bastard™

Appearance

So I definitely like the idea of him having sharp teeth and being shorter than cannon. I also think this boy would have BIG BONES to make up for the extra stress his quirk puts on them when his muscles are used. This translates into Izuku being a bit more on the chunky side, along with the natural ability to grow big muscles as, once again, a defense mechanism against his quirk. Sum up: he’s that dude that has always been on the bigger side and won’t get stick thin no matter how hard he tries, but when he flexes his arms turn into pure muscle and he can jump over your head from a standing jump. So basically chubby bulky

Also I thing he would be darker skinned since he runs around outside in the sun constantly to burn off energy, so he got at least a tan from all that

Quirk Apprehension Test

So once Flower mentioned that we totally just forgot about this part of the plot, I proceeded to laugh for like 5 minutes over the fact we did. I totally forgot this existed until you mentioned it. My idea is as follows

Aizawa: This test is to gauge your abilities, quirks, and potential to be a hero. You are to use your quirks during the test to increase your scores

Some idiot: This sounds fun! We get to use quirks!

Aizawa: Fun? How about this: whoever comes last gets expelled

Class: *shouting*

Shinsou: *worried because his quirk doesn’t help him physically*

Izuku, manic grin spreading across face and turns to Shinsou: *whispers* I have an idea. I’ll use my quirk to help both our scores

They then proceed to complete the test with Shinsou getting better scores than he should be able to get. Aizawa knows this since, while he doesn’t read the entire file on students so he can form his own opinions, he does look over the basic info of name, photo, and quirk name/description. Shinsou shouldn’t be doing this well, and he also acts differently once it’s his turn to preform. Aizawa sees Shinsou and Izuku being more comfortable with one another than they would be if they just met, and in addition to the fact they were together during the Entrance Exam, he guesses that they’re friends and Izuku is using his quirk to bost Shinsou. During Shinsou’s turn for the ball toss, Aizawa cancels Izuku’s quirk so Shinsou no longer receive its effects and throws the ball a lot shorter than everyone expected

Aizawa, glaring at Izuku: I knew it. You’re using your quirk to help your friend

Izuku, turning and smirking: And? What about it?

Aizawa: I could expel you both right now for cheating and interfering with results of a test

Shinsou: *face deadpan but shitting his pants, hoping Izuku will weasel their way out of this*

Izuku, gremlin smirk forming: No you won’t, Eraserhead. If you were doing this test you would have used your quirk to cancel your clasmates’ quirks to put you on a even playing field. I’m doing the exact opposite and helping. Plus, you only said “use your quirks during the test to increase your scores.” You didn’t forbid using our quirks to affect other people’s scores, nor saying we could only increase our own score.

Aizawa, cheshire grin: So you are related to your brother. Alright. Shinsou, throw the ball again and Midoriya, you can use your quirk

Shinsou, thinking: how is always able to pull us out of repercussions for our actions?

Battel Trial

Finally back to what this whole things should have been about! Jeez that took forever and I’m starting to get sleepy typing

Based on the pros and cons you gave and also what amusing me the most because I’ve writing this for 5 hours is that the Villains (Shinsou and Uraraka) should win.

Once Izuku gets over the fact he’s having to battle his basically second brother, Shinsou calms him down and tells him it’s fine, just pretend we’re sparing with Tenko again, he gets pumped af to brawl. Maybe a little too hyped up, since it makes his energy levels twice the ridiculous amount they were before and makes him even more jumpy and animated. Iida interprets this as him not taking things seriously and chastises him for it, which pisses Izuku off because he is taking it seriously. It’s just not being expressed in the way Iida expects it to be expressed. So, he’s definitely not as helpful to him as he could be while in the planning phase, and might have made things a bit harder than they needed to be when explaining the blueprint, just to annoy him.

Shinsou and Uraraka don’t have this problem and quickly come up with the idea to put the bomb on the roof. This is so Uraraka can use her quirk to send things high into the sky with only her nausea as the limit instead of the ceiling, and they’ll bring some more ruble and boxes up there too so she has ammo. She’ll try to stay as quiet as she can to guard and hide the bomb while Shinsou is a few levels below to make the heros think the bomb is there.

A trick they have up their sleeves is that Uraraka noticed that the blueprints had really weird airducts (something only she would notice because it’s so minor) and when they went to check it out, the airducts were actually tunnels disguised as airducts. So now the villains have a way of getting around that the heros don’t, and won’t be seen. With Uraraka directing him from the blueprints, Shinsou has his own private hallways! He can definitely use this in combination with his voice changer :)

I’m not too sure how the fight would go down, but some parts I think would happen is Shinsou trolling them from inside the tunnel with his voice changer. I don’t think he would spring the mind control on him just yet, Izuku taught him to have Fun™ afterall, and would switch between Inko’s and Tenko’a voices while messing with him. I just want my baby to create some psychological torture ok Another thing would be them finding the bomb on the roof and when Izuku’s about to grab it, that’s when Shinsou uses his mind control with AFO’s voice. I’m guessing they had some family videos with him in it so that’s how we knew what his voice sounded like.

Like you said when Izuku got controlled he was in a jump so when he fell he breaks out, but at that point Uraraka had moved the bomb and Shinsou is dealing with Iida. They’re running out of time so Iida and Izuku are starting to become a little desperate, so Iida yells at Izuku to use his quirk on him to make him extra fast so he can grab the bomb. He does, but Iida doesn’t expect it to be so powerful since the other times in the exercise Izuku used it on him he was holding back. Iida becomes a knockoff Sonic and shoot towards the bomb way faster than he expected. He didn’t expect to go the speed of Retro Burst without trying, so he overshoots it and ends up falling off the ledge near Izuku. He’s able to catch himself on the roof, but he’s not able to pull himself up without help and he’s starting to slip. Izuku has to pick between the bomb and Iida, and he decides to save Iida. While pulling him back up the timer goes off and the villains win.

Iida thanks him for saving him while Izuku just kinda goes “Duh, I wasn’t gonna let you get badly hurt if I could stop it. Annoy and inconvenience maybe, but not hurt. Of course I picked you. Anyways gotta go bug Hitoshi”

Just because Izuku is a dramatic bitch, while they’re walking back Izuku jumps unto Shinsou’s back and starts rambling to Uraraka and Shinsou about how cool their plan was, asking about the voices in the hallway and Shinsou’s new mask, clarifying some parts of their plan he didn’t get, and just generally being very animated and his talkative, analyzing self. Iida starts to think that maybe he was too quick to judge the green bean
