Alright, I know this chapter took longer than normal, but there is a reason. I have recently been on a Bioshock high recently, and to help get it out of my system, I've made a MHA fanfic with Izuku as an ADAM producer as his quirk. If you want to read it, let me know and I'll post it. Anyway, to the story!


They were in the middle of the track field at seven. The field was flat, with no cover. It was fine though; they didn't want any. Both had their hero suits on, upgraded from their initial designs in different ways.

"Alright, I'll let the two of you go hard, but no lethal force. Bakugo, that means no AP shots. Izuku, be careful; remember you can crush stone, and people are more delicate." Anima warned as he held up a firing blank. Katsuki's stance shifted while Izuku's mental trigger let him change his view. The gun went off, and the students were two bullets.

The blonde opened with a smokescreen, preventing his opponent from seeing his form. Unfortunately, that opponent didn't need to when Katsuki's aura was a beacon to his sixth sense. Ever since the trip to Kunlun, Izuku's chi was far more sensitive to change, letting him compensate for his lack of talent in sensing. A punch came from Izuku, grazing the explosive blonde across his bicep. Katsuki backed up before strafing around and jumping at the martial artist once again.

Only he wasn't there.

Before he could question where his opponent moved to, he felt an ax kick connect to his shoulder. Grunting, he created another explosion to clear the smoke that was obviously not working in his favor. Izuku was standing a fair distance away, not a scratch on him, while Katsuki was sporting two impressive bruises. He charged again, and Izuku threw him, but not before the blonde tagged his calf and skidded on his hand to a stop. Izuku noticed the odd action, but was too late in realization to move. The explosive teen ignited the trail of sweat and singed the martial artist's limb.

Izuku knew that the pain in his leg was for superficial damage, But burns were disproportionate in pain compared to its actual damage, limiting his movement. His stance changed, and Katsuki was thrown off by the different moveset. This wasn't an oriental style; this was African!

Izuku's stance was from a secluded country's Lion tribe. It was lower to the ground, making Katsuki have to be careful not to throw himself with his own explosions as he took kicks and palm-strikes from lunges that seemed to have no sequence. The fight changed in Izuku's favor for a while until Katsuki figured the rhythm out. Then he waited until Izuku pounced, and decked him in the face. The greenette lowered his head enough that it connected with his forehead and not his eye. He then switched style again to the country's Spider tribe, focused on grapples. He threw Katsuki to the ground before pinning him. He then saw the blonde smile.

It wasn't his palms that were a high-grade explosive, it was his sweat.

The only warning was a spark, and Izuku disconnected just as Katsuki's back blew him upwards. Izuku shifted in the air to roll with his landing, just as his opponent sped towards him, throwing explosive blasts, kick, and punches in an almost non-stop flurry. The martial artist focused on deflecting and dodging, waiting for the chance. All weapons -even the body- needs a moment of downtime to prepare the next onslaught.

Katsuki slipped on the ground from his gauntlets pulling his weight too off balance.

Izuku didn't hesitate and solidified his stance before stepping in. Katsuki blew up his left hand, changing his rotation in the opposite direction, though it was dodged. Izuku landed a kick to Katsuki's rib, making an audible crack, and making it hard for the blonde to breathe.

Off to the side, Anima paid close attention to both individuals, making notes about their differences and looking out for a reason to stop them. The werewolf noticed that while Izuku had rigid technique, bakugo's instincts were helping him connect every strike in a fluid form. He saw that every time the two engaged, Izuku's hits were in debilitating areas while Katsuki's were where he could easily nail his opponent. Unfortunately, those were where it wasn't as important, such as his abdomen and forearms, that could take the impact with little effect on the chi user's fighting ability.

While Katsuki was dangerous with his instinct, against someone physically stronger, tougher, and faster with more precise strikes, the blonde was going to lose.

After thirteen minutes of impacts, waiting periods, and dodging, Katsuki was thrown one last time, fracturing his arm and dislocating his collarbone. Izuku was covered in burns, bruises, and even sporting a cracked shin, but his opponent wasn't able to fight anymore.

"Izuku wins." Anima announced before picking the explosive blonde up and walking to Recovery Girl, Izuku limping beside. Katsuki looked over at his rival, and grinned.

"Fuck. I gotta learn how to fucking keep you down; I smacked your ass around more times that you hit me, but I'm the one that feels like shit…" the explosive teen moaned.

"Placement counts more than force, and I have both." the martial artist pointed out. While the victor was clear, neither felt it was a cheap win.


"I can't believe you agreed to let them fight to this point!" the school nurse said infuriated. "I swear. Just because I can heal the students doesn't mean you should just let them beat on each other!"

"I'm not saying heal them 100%. Just enough they can continue their schoolwork." the werewolf said. He knew she'd help them, but leaving them covered in bruises would let them know how dumb the fight was. "And if I didn't agree to the fight, they'd do it without supervision. I'd rather be able to stay close and prevent crippling injury or death."

Recovery Girl wanted to ask him what"crippling injuries" counted to him, but remembered he had most of his flesh blown off in the finals and was still in the fight. Sighing in resignation, she used her quirk on the boys, healing the worst injuries, but leaving the bruises and cuts to not drain them of all of their stamina; the license exam was in a week, and they'd be healed by then.

"Thank you." Anima bowed. He then picked Katsuki up in a fireman's carry and left to take him to his room. The elderly hero then turned to Izuku. The green-haired martial artist was lying in the bed.

"From what I heard, your friend was the one to issue the challenge. Would you mind telling me why you accepted?" Izuku closed his eyes and thought for a moment.

"I wanted to see who was stronger." he said succinctly. There was a pause as if the nurse was expecting more. When she didn't get anything else, she sighed.

"And with a broken bone, and several bruises as your reward, was it worth it?" Recovery Girl questioned.

"Yes." there was no pause in his answer. Sitting up, Izuku tried to explain it best he could. "I've always had Kacchan in my life, as a sort of bar to reach. He was confident, strong, driven, everything I admired. After training with Anima-sensei, I never really lost that idea. Even though we were challenging each other for years, he and I never actually had an all-out fight to see what was better; instinct and brute force, or training and control. I guess we just wanted an end to the argument."

The elderly nurse looked at her charge, and the small fire in his eyes. She knew nothing else she could say would change his mind, and from his words, the matter was settled. Taking a breath, she decided there was nothing else to say.

"Alright, but don't let this happen again." she told Izuku, who nodded. "Now go on back to the dorm rooms. And I don't want you going out tonight."

As Izuku left, Chiyo went back to her work. She knew that boys would be boys, but they really did a number on each other.


"You guys look like crap!" Denki told Katsuki and Izuku the morning after the fight. The explosive blonde leveled a glare while Izuku gave a creepy smile.

"Thank you for stating the obvious, Kaminari-san." Izuku said smoothly. This made everyone turn to the chi-user in shock.

"Damn, how bad is it?" Mina asked. The greenette's smile turned more natural.

"I feel like a walking bruise." he said. "It's not the worst I've felt, but without counting broken bones, it's up there."

"Wait, how many times have you broken bones?" Toru asked.

"I've lost count, but it's been enough times that some of my bones are not in the same shape that I was born with." Izuku noted. When he saw everyone look at him, he sighed and rolled up his sleeve. "If you feel along my forearm and shins, the bone is bumpy instead of smooth; it was something throughout Anima's training." sure enough, the few classmates that felt under the teen's corded muscle noticed how rough it felt.

"I take it he was using Wolff's law?" Ojiro asked, and Izuku nodded.

"What's Wolff's law?" Uraraka questioned. Surprisingly, it was Eijiro who filled the class in.

"It means that bones get stronger over time due to the forces they take. Microfracturing bones again and again over time is how many athletes get to the point of breaking cinder blocks with their bare hands." seeing eyes on him, the redhead blinked in confusion. "What? Anima's doing the same to me during martial arts class; he says it'll make my hardening stronger if I strengthen my unhardened form."

"Anyways," Momo piped up. "What do you suspect we'll face in the license exam?"

"Well, they are wanting heroes." Izuku noted. "So there'll be a test on combat abilities for sure, but we're all pretty good on that front. There's also a good chance for a rescue or hostage situation, as heroes are supposed to save lives, not just beat up the villains. I suggest asking Ectoplasm-san if he could make clones and put them around the USJ and let us rescue them. If we coordinate with class B, then one class can act as the rescuers while the others can act to hinder us like villains in a real situation."

"That is a wonderful suggestion Midoriya-san! Let's ask Aizawa-sensei if it would be alright to do so." Tenya exclaimed. Walking to class together, everyone sat down and waited for homeroom to come around. When the bell rang, Shouta walked through the door.

"Alright, as you know the test is next week, so training is going to be upped appropriately. Yes, Asui." he said as the frog girl raised her hand.

"Midoriya made a good point on our way here; would it be alright to train in a rescue scenario at the USJ? For our hero licenses, it would make sense if they tested our abilities to rescue people during a villain attack." she said without hesitating. Shouta looked around, and realized how little he taught them to actually save lives like heroes.

"Alright then. Due to the small numbers in class, I'll ask Blood King if he would like his class to join us." the perpetually exhausted teacher agreed.


Wow, this took longer than I thought. Not due to difficulty, but due to the stuff irl. anyway, if you enjoyed this, please leave a comment. Till next time!
