Chapter Text
Izuku Midoriya stood inside his kitchen, mumbling up a storm like he usually did when deep in thought. Now, one could guess he was thinking about UA's first school day coming in two and a half weeks, passing the entrance exam (breaking both legs, and right arm), or how to better control One for All, but they would be wrong. As he was busy trying to boil an egg without water… "So, if I place the egg upright, turn the dial to low power, and give it enough time, the egg should cook without bursting, avoiding a mess. I don't want to clean again, alright, let’s try it".
While he was setting up the egg, his mind fell to the conundrum that was One for All. Clearly All Might's advice wasn't completely right, now Izuku would never say that All Might was wrong, but it obviously wasn't going to work with him. "If I just charge the tip of my fingers… nah that would just give me 10 or if desperate 20 shots before I need to break a bigger body part, maybe controlling the output?" He tried it on his arm, seeing if he could lower the power to somewhere around 1 to 3%.
Green lightning started flashing around his arm, and he just stared at it in shock. It didn't hurt, his arm moved quite a bit faster, and the lightning looked awesome. "I can't believe it worked!! I need to start training this now, I don't want to break more bones if possible, now how much can I manage before it hurts?".
He slowly upped the power, for now it took a lot of concentration, but he knew with practice it would get better."Okay 3% is fine… 4% stings a bit, nothing mayor… Ow ow owowowo, okay 5% hurts quite a bit." Cutting the power he noticed how his arm felt like after his workouts, but this was a huge breakthrough in his control. " Can't wait to show All Might!"
Now in a better mood that ever, he checked the progress of the egg, and decided enough time had passed. Grabbing it from the microwave, he looked it over to see if it cracked.
Seeing it was fine, he took it to a small bowl to check if it was cooked like he wanted. And as if his mood couldn't get better, it worked. It was as if boiled, meaning the heat spread evenly on it instead of focusing on one point, or being too much, and bursting… "huh… probably nothing."
Dismissing that feeling of missing something, he grabbed a spoon, and took the egg to his room. Eating it while writing his new training plan for the next two and a half weeks.
After a week of secret training, given he wanted to surprise All Might with his increased control over their quirk, Izuku found out 3 things.
One, with practice like he thought before, it did get better to channel the power on his limbs.
Two, his strength, agility, and reaction time were increased when focusing on his arms, legs and head (tested by throwing things in the air, and dogging at the last second) respectively.
Three, in a real fight he wasn't sure he would win... It turns out, while his activating got faster, his transfer from one limb to the other was slow enough to be a major weakness.
Doing his routine again of lifting weights, sprinting, and just pushing the power through his limbs. He just fell in a heap of exhaustion on the sand of Dagobah beach. "This isn't working… maybe I need to just speak to All Might. And here I was thinking I could surprise him without having problems."
Later that night while doing homework, he was eating his new favorite snack, contemplating his problem with One for All. "kay so the transfer takes about 100 to 300 milliseconds, depending on the limb and the proximity with the previous augmented one-" once in his mumbling mode, he stayed like that for 15 minutes before looking at the cold half eaten egg to his side… when something like a lightning bolt, went through his entire body "no way, no way …." Face palming he realized, he never tried using One for All on his entire body at the same time. "I'm so stupid sometimes".
Finishing his homework, he went to bed early "Tomorrow is Sunday, so I can call All Might, and try it with him all day if possible." He went to sleep thinking about his mentors face when he sees his progress.
The next day, All Might was waiting for him at the beach, in his skinny form. He approached the 1# hero. ”Young Midoriya, how are you doing?. In the phone you said you had a surprise for me?”
“That's right, so, remember that I broke my limbs at the entrance exam?”
All Might faltered a bit at that. “yes.. how could I forget…”
“well, look at this.” He extended his, arm and activated One for All.
All Might’s eye went wide when he realized what was happening.
“Your are using One for All!. Amazing, so much progress in so little time. I knew I chose right!.”
He blushed at the praise, but he wasn’t done. “Now, let me show you my findings, and then you can help me try out a solution to a problem I'll explain in a bit”
“Of course” The proud smile he gave Izuku got him blushing again, but he pushed through it.
He went about explaining what he found, as well as demonstrating what he could currently do, including how he got to this point in the first place.
“So, let me get this straight. You were… making a ‘not boiled’ egg, when the idea came to you?”
“That’s right” he nodded.
“And you can control 3% no problem, up to 5%?”
“Eh, now it should be 4-ish%” he gestured with his hand.
“Okay, now I really know I made the right choice, this is incredible progress, young Midoriya”
He waved the praise away, since he started explaining he's gotten constant compliments, so he was getting a little better handling it, he blushed anyway.
“And that brings us to test the fix to the delay issue”
“Right you said that it took too long to switch extremities, right?”
“Correct” Nodding along he explained the solution.
“So now I want to try to channel One for All through my entire body, thus eliminating the delay entirely”
“Ok, just remember to start slow, I’m here if you need anything”
Nodding, Izuku got into a loose stance, starting with his legs, he concentrated as he continued to channel the power at 1% throughout his abdomen, chest, now arms, neck, and finally his head. Once he finished spreading the power, he just stood there getting used to the sensation of the quirk everywhere on his body.
“So? How do you feel?” All Might asked a little worried of his prodigé.
“It's taking me a bit to hold, but the previous training certainly helped.”
“Other that that?”
“I feel free… it’s weird” he inspected his arms as he tried to explain. “it's exhilarating, all this power, even if it just 1% going through me”
“Try increasing it slowly” asked All Might.
He nodded, and started to add power. “Okay 2% is fine... if this feel like this, at this level I can't even imagine what you felt in your prime, or even now,” he explained in wonder.
“It is an amazing feeling yes, but is also a dangerous power, you have to be careful with it.” Toshinori added to remind the boy of what he’s capable.
He nodded, more determined than ever. “Okay 3% is also fine… 4% is fine too!”
“Okay try 5%”
“...5% stings a bit, so is probably better to train each percentage to eliminate the sting, and then go up form there. I could train at the highest possible but, it’s better to pace myself instead of cutting the training short due to injury or exhaustion-”
“Young Midoriya, you're mumbling again”
“AH, sorry,” he apologized while rubbing the back of his neck, and cutting the power.
“Well now that we know your limits, let’s start,” said All Might while buffing up.
Growing in excitement, Izuku turned on One for All, and got ready to spar with his idol.
He decided this need it a name...
“One for All: Full COWL!!!”
