AN: This idea is one I got when it was established in one of the movies that Quirks could be attained by transplanting quirk factor from one person to another. We also know that it doesn't always take and can take with varying degrees of success. I got this idea by considering what organs could be replaced (I looked up and found there were six organs that could get transplanted) and how it would work if each had a shard of the quirk factor from their original user inside them.

AN2: Again, not the first chapter, just a first look.

Shards of Power

-Nezu-

Humming happily to himself, Nezu kicked his legs as he rode on Recovery Girl's shoulder, cheerfully ignoring the strange looks that this garnered from the various hospital workers they passed as they made their way to the secure rooms. "Must you ride like this everywhere sir?" Recovery Girl grit out, her eyebrows twitching irritably.

"You signed the contract." Nezu beamed, glad he slipped in the clause that they had to let him do this into every UA employee contract.

"One day I'm going to shave you and there will be nothing you can do about it."

"Rude." Nezu mock huffed, well used to that particular threat that she'd never actually enacted. The rest of the trip was spent mostly silent as they wondered why they were called into the hospital.

"Good, you're both here." Spotting one of the head doctors, Nezu noticed the man seemed quite frazzled "This…we may have made a breakthrough in Quirkology but if word got out, I'm positive there would be a massive upsurge in crimes all around the globe."

"How would a medicinal discovery cause crime?" Recovery girl narrowed her eyes, demanding an answer straight away.

"The subject, one Izuku Midoriya, was admitted to the hospital recently. He was caught up in that Villain attack in Mustafu, he's the kid who got caught between the attacks of the villain and that idiot 'Pro' who didn't bother trying to avoid civilian casualties. The kid's organs were badly damaged resulting in him needing replacements for his Heart, kidney, pancreas, intestines, liver, and a lung." Even Nezu felt his eyes widen at that. Transplants weren't all that common anymore, given the nature of healing quirks most people either didn't need a transplant because they were healed quickly enough, or they were too far gone to save. Still, thanks to quirks and modern medicine most hospitals had a store of organs that could last for decades and be fine, just in case.

"While horrible for a child to endure, I fail to see how it's a medical breakthrough." Recovery girl gestured for the man to get to the point.

"The organs took to the boy…far more than expected." The Doctor gestured for them to follow "When he was admitted our systems were down so we couldn't pull up his medical record, we just confirmed with his mother that he didn't have any allergies. When the head physician saw these journals on him," the doctor held up a stack of journals labelled 'Hero Analysis for the future' "they assumed the kid had an amazing quirk to be this invested in being a hero, so he ordered all the stops pulled out." Nezu wanted to sigh, well used to this society trying to curry favor with children with strong quirks in the hope of cashing in when and if they became big heroes.

"I'm guessing his quirk wasn't all that impressive?" Recovery girl snorted.

"He was quirkless." The doctor replied as Recovery girl winced, Nezu however noticed something important.

"I'm sorry, did you say was?" Nezu pressed the issue.

"Hence the breakthrough. It seems the transplants took flawlessly, actually giving him a weaker version of all the quirks of their original owners. We've determined four of the potential six quirks so far." The doctor's explanation explained why they were going to such a high security area.

"Transferred the quirks?!" Recovery girl likely had the same thoughts he did.

"We aren't sure exactly how. It could be due to his nature as quirkless, a trait that's becoming increasingly rare. It could just be a one in a million miracle with how compatible the organs were with him. It could be a side effect of those or more, I did check and saw that the blood transfusion we gave him tended to boost the healing of those who get it injected into them for a period which might have had a factor. As I said, this is something we don't fully understand but if the general public learned that someone gained quirks just by organ transplant, we'd have villains on an organ harvesting rampage. The Government has been informed as well so a cover story could be made, I asked you two here to help and study the situation, given your mind Nezu and your medical history Recovery Girl."

"What quirks has he gained." Nezu demanded, already trying to process the situation as he looked through a window to see a green haired boy with his mother, all surrounded by doctors and scientists.

"As I said, we figured out four so far." The doctor pulled out some files "We're digging into the other two organ transplants to be sure on that front. First, we have a hardening quirk, once used by a man named Ling Yao. He could harden his entire body into the strongest possible formation of carbon, Izuku seems limited to having that hardening go from his hand and feet to halfway to his elbows and knees."

"So, all of these have more limited versions?" Recovery girl took the file.

"Yes." The Doctor nodded "Second we have a quirk where the original owner could shoot condensed beams of fire out a great distance, Izuku's are quite short although they do pair well with another quirk of his. The third one is a stockpile quirk, where kinetic impacts are transformed into an electrical charge that could be released at will, although the impact is still felt. The original user didn't seem to have a limit to how long he could hold the charge although Izuku can only hold the charge for a few minutes."

"And the final quirk?" Nezu pressed, "I have a feeling it's the one that you said would pair well with the short distance flames?"

"Yes, the original user was one Nana Shimura," Nezu almost fell off recovery girl "who could fly at the height of her power. It seems her heart has given Izuku the ability to float, when paired with the fire he has thrusters."

A side glance with Recovery girl showed she recognized the name too, "We'll help." Nezu promised, silently hoping All Might didn't freak out when he learned of the situation.

AN: Like I said, shards of other quirks, a bunch of weaker powers rather than one big one. Still unsure on last two, I'm trying to think of something that would be functional with the others.
