"Alright...try standing up now," said Izuku, as he was calibrating the device that would help Iida's brother walk again.

Tensei carefully put a foot down. When the doctors said he'd never walk, much less be a pro hero again, he had been devastated.

And then his little brother's classmate showed up to get some measurements and gave him a promise that would at least be mobile on his own power before the end of the year...free of charge.

He had been dubious right until he discovered he had actual feeling in his left foot again.

Tenya had been beside himself after he was able to move his left leg.

"So how does this work again?" asked Tensei, trying to distract himself.

"Have you ever heard of Nanoman?" asked Izuku.

"Not particularly."

"He's a quirkless hero who was forced to retire because the QRA found out he lied, despite the fact he was actually rather successful. However it didn't stop him from developing his tools even further and progressing the research on nanomachine technology. Thanks to a collaboration effort with him...and the fact he was fascinated at the idea of what it could mean for the medical industry...we were able to develop a prototype that basically uses the remaining bone in your legs that were ruined as the material for the nanomachines to rebuild the structure of your legs. However it's still a prototype."

At least that's what everyone would assume. Izuku had developed this after he had become good friends with the Ingenium of his time...who happened to be his classmate now. He had been rather drunk on the anniversary of the Hero Killer's attack on his brother and asked Izuku if there was a way to help him.

It took a lot of trial and error, but he eventually developed a prototype set of nanomachines (with the help of a retired hero who was fascinated by the idea) that would essentially "eat" the bones that had been broken and use it as the material that would rebuild the legs from where the break stopped.

It was groundbreaking research...one that lead to a number of injuries that were previously untreatable to be fixed. Several of the older heroes who took trauma to the head and lost the majority of their eyesight and had to retire were shocked to find they could suddenly see again.

"Then what's the brace for?"

"Same scenario as a broken leg...the machines will need time to work in order to rebuild the shattered bone, but in order to do so they need to be stabilized first. If you tried to walk on a broken leg without a cast you could easily cause it to heal wrong. This is to insure that the bone regrows the way it should," said Izuku absently.

"Makes sense. What about my quirk?"

Izuku looked him in the eye.

"Unfortunately we haven't gotten to the point where we could heal quirks. A bone is easy...we already have the roadmap built over countless centuries to how it's supposed to work and function, we just needed to program the machines to follow that map. A quirk is too recent and too varied for them to reliably work."

Tensei sagged. At least he would be able to walk again.

"There's also the fact that since this is new technology, there's no way to determine how strong or solid the bone will be. And you know how dangerous villains can be...one wrong hit and you would be permanently disabled."

"Thanks for giving me a straight answer."

"I prefer to give my clients a realistic knowledge of how my tech works...even if all I did here was create the brace and help adjust the programming of another hero's work," said Izuku. "Sometimes life throws us major curve balls that cause us to find a new direction. The only thing we can do is get on our feet and keep moving forward."

"You're a lot wiser than most think," said Tensei.

"Besides, this gives you a chance to show off your new scars and hopefully get a wife. There's no greater trial than fatherhood," said Izuku cheerfully.

He had learned that the hard way with Eri, not that he was complaining.

Izuku finished adjusting the brace.

"Okay...now we just need to let the machines do their work, so no trying to get up for at least two days. Next time you see me, we can check to see the progress of the machines and the brace. With any luck you'll be walking in a month or two, thanks to physical therapy."

Iida was beside himself with tears when he watched his elder brother slowly start on the long road to recovery. He would become a lifelong friend of Izuku's as a result.

On an unrelated note, his brother followed Izuku's advice and started dating a nice girl that he later married.

"Great...I still can't get the calibration down...and without the right clearance level the materials I need to even make this are out of reach," said Izuku tiredly.

It was a pet project of his...he got a lot of really fun ideas from different series, and one of them happened to be a favorite of his. Or at least the weapons anyway.

He was trying to recreate the wire-based weapon used by the character who shared his hair color, even if he didn't share the man's perverted attitude.

He had managed to recreate it in his original time line...even if there was an incident which resulted in his name losing favor among the public.

Lubbock's weapon was impressive, but a complete pain in the ass to recreate.

And as if he didn't have enough headaches, Endeavor had sent a 'request' for him to join in on one of Sakura's training sessions. And the wording alone made it clear it wasn't a request, but a demand. He was already pissed his daughter was dating All Might's apprentice. He would never support her goal of becoming a hero-based fashion designer or that she fully intended to marry someone who would likely be the second coming of his hated rival.

Oh well...at least he would get SOME amusement from the overdue asskicking of that blowhard.

Two days later...

Endeavor sneered at the boy who dared to date his daughter and greatest work.

He barely noted the explosive teen present. Being humiliated with a peer watching was sure to hammer in the fact he wasn't worthy of his daughter.

He didn't really register the fact his daughter and the other teen were holding up cameras...right up until the moment his quirk suddenly stopped working.

The green haired fool looked entirely too smug at his shocked expression.

"Now, I believe there is a matter of the amount of grief you've given your family over the years that needs to be settled?"

Endeavor sneered at the boy... he was a mere child compared to him.

The moment he said begin, all hell broke loose.

Izuku touched something under his shirt, and without any warning his quirk suddenly stopped working.

Bakugo was already sneering at the asskicking the number two hero got from his best friend. Izuku may not look it, but he was a powerhouse who knew martial arts. His body was compact, rather than bulky which meant people tended to underestimate him in a fight since he preferred to use his gadgets rather than his actual strength.

Sakura was rather glad her boyfriend had given her a high quality video recorder for this moment, because honestly? She wanted to replay it over and over as many times as possible and she knew her mother and older sister would want to rewatch this scene as well.

Because there was absolutely nothing that could top Endeavor getting his ass pwned by a kid half his size and age without using any quirk or device other than the Eraser Kitty. And when they took that out of the equation, Izuku hadn't hesitated for a second to kick Endeavor so hard in the balls while using One for All that she would swear one of them burst. The overbearing jackass was sent flying and far away from the home.

"Have I ever said how much I love you?" said Sakura.

"Not since the last time I kicked his ass."

She kissed him, hard. If it wasn't for Fuyumi walking in she would have gone into a major make-out session with him.

On an unrelated note, Endeavor had to take a leave of absence for an unspecified training injury that he refused to disclose. Sakura was just glad she now had viable blackmail on her "father" that she could use to get him to back the hell off.

Unless he wanted the fact he got his ass handed to him by a fifteen-year-old who happened to be All Might's apprentice made very public.

"Thank the gods that we did combat practice damn near every day...otherwise handling my quirk would have been a total pain."

Izuku never had a quirk before, and to be honest Sakura always enjoyed their mock fighting. Having to deal with the added factor of a quirk Izuku was still working the kinks out of had given it an added factor of fun.

Izuku didn't feel bitter about being quirkless. He had actually felt smug once he finally got the Eraser Kitty working, because he could kick the ass of the high and mighty down to size. After all, he wasn't affected by the device while they suddenly had to deal with the fact they lost the one thing that made them feel superior to others.

But now... now he could proudly say he was inheriting All Might's legacy.

"I can't believe you managed to get my mom out of the hospital," said Sakura.

"To be fair, the doctors had already noticed something was off about her diagnosis but they couldn't do anything because of that jackass. The main reason they couldn't release her was because the only place she had to go back to was that house which would be impossible considering he caused this mess in the first place. Fortunately Kaa-san was okay with yours staying in our home since I could just as easily move to the dorms to free up room," said Izuku with a shrug. "Actually Kaachan said that he'd move to the dorms too."

"Not surprising...after you revealed what happened he's been less of an ass and the two of you have become rather close," said Sakura. "By the way, what did All Might want to talk about after the rescue class?"

"Something rather important from the way he talked about it. I have the distinct feeling I'm about to get my first super villain...only it's inherited."

"Would not surprise me, but so help me if you start making Joker or Lex Luthor references I will freeze your boxers again," said Sakura seriously.

"And you said you didn't read my comics!"

"I'm a Marvel fan over DC, and I will make you suffer take out for a week if you tell anyone," said Sakura.

"Yes dear," said Izuku smiling with a laugh.

Hearing the story behind One for All was fascinating. All Might believed that Izuku might be the one to finally deal with All for One once and for all thanks to his gadgets.

That man relied on his stolen quirks... Izuku's Eraser Kitty was just the sort of thing that could deal a devastating blow to his powers and those of his allies, and Izuku used One for All to augment his natural fighting style, rather than rely on it like All Might and the others before him had.

That plus there was one thing All Might didn't know about Izuku...the green-haired teen wasn't afraid to kill if it meant protecting others. How many innocent lives could have been saved if Batman had simply bitten the bullet and taken out Joker and his insane girlfriend once and for all?

At least in the Marvel verse, they weren't afraid to put down their dangerous enemies in a more permanent fashion.

A few days later, the students got news that would devastate the less academically inclined.

Those that failed the exams would be stuck in remedial hell while the others went to a summer training lodge.

Izuku was secretly cackling at the faces of the others, since he was in the top five of the class.

Finding out he would be facing All Might in a spar with Kaachan had come as an amusing surprise. To be honest Izuku was rather eager to see how they could fight together.

It was a complete and utter disaster. He might have patched things up with Kaachan so that they were friends again, but Bakugo was absolutely terrible at teamwork exercises.

Fortunately Izuku had experience with ill-tempered heroes, so they managed to pass the exercise...but Bakugo was still pissed because they had only passed due to Izuku tripping up his favorite hero while he tossed Bakugo through the designated exit.

A few hours later...

"How did you do?" asked Izuku.

"We managed to pass...barely," said Sakura. "If I didn't have the extra experience fighting with your Eraser Kitty, we would have had our asses handed to us."

"Look on the bright side...summer vacation is upon us!" said Izuku.

"Too bad we're a year or so shy of taking advantage of that fact," snarked Sakura.

"Considering how often certain 'accidents' happen, I'd rather wait until certain 'preparations' were made before we moved to that step. Besides, we're still in the early stages of properly dating this time. I want to actually enjoy it," said Izuku. "Moving too fast would just spoil things and I want to properly court you rather than jump back in to what we had."

Sakura blushed at that, but didn't complain. Besides, she knew her boyfriend...he would rather wait until they found his baby again than rush things.
