Author's note: Hey everyone, FireSlash here and welcome to the next chapter of Iron Deku. Before we begin, allow me to thank all of you who took the time to read, favorite, follow, and/or review this story. It means a lot to me. Now, I want to give you all a heads up: I plan on releasing another Marvel/MHA fic sometime this week, so be prepared for that. The concept? Let's just say it involves an infinity stone. It'll be a smaller and more light hearted fic. As for this story, remember how I said Izuku will be more confident? It'll show in this chapter. I kinda want his character to be a blend of cannon Izuku and Tony (w/out the alcoholism and arrogance).

With that out of the way, review and enjoy :-)

"You have your tissue?"

"Yes mom."

"How about your handkerchief?"

"In my bag."

"Lunch money?"

"Got it."

"Well, what about-"

"Mom, It's ok. I got everything. Did you forget who you're talking to?"

"I'm speaking to the same boy who lost 10870 yen even though it was right in front of him."

"...I thought we agreed to never speak of that again…"

"Sorry, I couldn't help myself."

A few months have gone by since Izuku got his acceptance letter from U.A and he was now preparing for his first day at his new school. Like most high school students, he had all the basic supplies he needed in his bag. His outfit was a different story though, it being a miniature version of his armor. Compared to the Mark II, the small armor he was wearing, named the Mark Mini by the inventor, lacked most of the offensive primary functions needed for it to fight crime. Designed as more of a support suit, the Mark Mini was only about as thick as a coat, lacked flight, and only allowed the wearer to lift a maximum weight of two tons. Powering it was a mini reactor in its chest, the armor not needing as much power as the Mark II. It's only means of attacking was through the reactor as well as the increased strength it gave its wearer. It even lacked a helmet, the armor being made for portability. Now if he were in the hero course, he would've taken the Mark II without hesitation, but since he was in the support course, he felt taking anything bigger than the Mark Mini wouldn't make much sense.

Having calmed his mother down, the boy began to leave his home, ready to start the new year. "I'm gotta go now. I'll see you later."

"Izuku, wait!"

Turning around, Izuku was starting to feel impatient, not that he'd ever show said importance to his mother of course. He loved his mother dearly, but her fussy nature was sometimes a bit too much considering his status as a super genius. "Yeah?"

"I'm so proud of how far you've come without a quirk. You're really cool."

All his impatience died upon hearing this, the boy quickly giving his mother a hug. Once they seperated, Izuku gave her a smile of appreciation before leaving.

"J.A.R.V.I.S, call Mei for me please," Izuku told his A.I though his small earpiece as he began walking to school. Just as expected, the pink haired genius had also made it to U.A, them even being in the same class; class 1-H. Being the antisocial boy he is, Izuku was glad that his only friend would continue to stay by his side. With them now attending the same school, the two decided they would wait for each other at the front gate every morning and that they'd walk home together every night, hence why Izuku was currently calling his fellow inventor.

"Understood. Calling Mei Hatsume." Doing as his master ordered, J.A.R.V.I.S began phoning the girl, causing his earpiece to make a few ringing noises. After what seemed like an eternity, she finally answered.

"Yo, this is Hatsume, how can I help you?" The girl asked in a strained voice. If he had to guess, his friend was currently struggling with something.

"It's Izuku."

"Hey Zuzu." Izuku bit back the urge to groan. Just like Katsuki, Mei came up with her own (abit uncreative) nickname for her friend. It was a bit embarrassing, but he knew she was doing it out of affection, hence why he let it slide. "Whatcha need?"

"I just wanted to let you know that I'm about ten minutes away from U.A."

"Sweet! I'll man down the fort-" as she said this, a loud crashing sound echoed through his earpiece as someone fell. "Dammit!"

"You ok?"

"Yeah. A few of my babies just fell out of my grip."

"...Mei, how many 'babies' did you bring to school?"

"Not a lot…"

"Why am I not buying that?"

"Ok, fine! I bought ten of my newest ones."

Izuku began pinching the bridge of his nose. One wouldn't be able to tell by the quality of her work, but unlike himself who only focused on one project at a time, Mei loved cramming as much as physically possible. "Mei, what makes you think bringing ten dohickeys to U.A is a good idea?"

"Hey, I wanted to use their sweet support labs to put the final touches on them!"

"...Where would you even store them?"

"In either our homeroom or lab. If not, then I can just carry them."

"You mean, you'll have me carry them."

"Yep." He could practically see the shit eating grin on her face.

"Whatever, just stay put and don't let any of your 'babies' cause any harm, alright?"

"Aye, aye captain!"

Hanging up, Izuku smiled as he looked up to the clear sky. Today was definitely going to be a good day for him…

"Glad to see you haven't blown up the school...yet," Izuku playfully remarked as he approached his friend. Staying true to her word, the pink haired girl stood in the same spot until he arrived.

"Of course I didn't," Mei playfully pouted. "Who do you think I am?''

"You're Mei Hatsume, enemy of labs everywhere…"

"Oh come on! I don't blow up my lab that much…"

"Last week alone, you blew up your lab a total of twelve times while you blew up mine twice. As for how many times you blew your lab up since I met you, I've honestly lost count."

"As if you're any better Mister 'let me cause a citywide blackout just to test out my newest invention.'"

"Oof, you had to bring up that old wound." Chuckling, Izuku turned to face the school. Now that he was taking a good look at it, the place was enormous, definitely bigger than he remembered it to be when taking the exam. Then again, he didn't really pay much attention to the building when he arrived for his presentation, he being nervous and all. "So, this is it. We're finally students at U.A Academy."

Mei walked up to him and placed a hand on his shoulder. "Amazing isn't it?" Eventually removing her hand, the girl's chirpy smile returned as she handed Izuku a pile of inventions. "Well, let's get to it! I dunno about you, but I sure as hell don't wanna be late on the first day."

Watching his friend, the boy shook his head in amusement before following after her, only to realize a second later what he was holding. "Get back here Mei! There's no way I'm letting you use me as a lift again!"

0000

When the two teens entered the building, they wasted no time, immediately beginning their hunt for their classroom. As they searched, Izuku tried his best to give the girl back her belongings, only for her to give him her best impression of the face of a kicked puppy, said face being used whenever she wanted something from her best friend. Unfortunately, Izuku couldn't resist the cuteness and ended up doing it for her. At least he had the Mark Mini to help him out…

"1-H, 1-H, geez this place is like a maze," Izuku mumbled under his breath, Mei nodding in agreement.

"It doesn't help that these doors are huge…"

"I think they did that to accommodate people with height altering quirks," Izuku informed her before checking another door. "Ah, looks like we're here."

"Cool."

The two stood by idly for a few seconds after finding the door, Izuku expecting Mei to open it while the girl in question expected him to do the same.

"Uh, Mei, aren't you going to open the door?"

"I thought that was what you were doing. I wouldn't be standing here otherwise."

"I'm holding all of your 'babies,' how do you expect me to open anything?"

"Oh stop being such a drama queen." Playfully rolling her eyes, Mei swiftly opened the door, it being a lot lighter than it looks. "There, it's open, happy?"

"Very," Izuku dryfully replied before entering the class, Mei following behind him. Looking around, the two noticed they were the first to arrive, the classroom being completely empty. "Huh, looks like we're early." Quickly glancing at the clock, the two realized they were about ten minutes early. "You'd think everyone else would be here by now, seeing as this is U.A and all…"

Shrugging, Mei began walking towards the left most desk in the back of the room. "It just means we get to pick out our seats first. C'mon, let's grab one in the back. I know how much you hate attention."

Having no reason to complain, Izuku took the desk next to her, gently placing all of her inventions behind them. The two then began to engage in menial chatter as they waited for their homeroom professor and the rest of their classmates to show up. From the corner of their eyes, they soon noticed more and more students enter the room, each going off to do their own thing. Finally, their homeroom teacher arrived. For a teacher, the man certainly looked unprofessional. For starters, the man wasn't wearing a shirt. In addition, he was wearing a helmet which looked like the claw of a bulldozer. Normally, a teacher wouldn't be allowed to wear such attire, but U.A was a special school, being taught by pro heroes themselves, most of them choosing to work in their hero costumes. Such a place was basically heaven for Izuku who was able to recognize the pro hero instantly.

"Mei, check it out! It's the pro hero Power Loader," Izuku whispered to his best friend before he began spitting out information about the hero. For once, Mei was able to understand her friend's verbal diarrhea, being a fan of the hero as well due to his work in the support field.

"Woah, when I heard they had pro heroes teaching our classes, I didn't think we'd actually be getting the big guns."

"Alright, that's enough chattering from ya," Power Loader said, quieting the class. "As most of ya already know, the name's Power Loader and I'll be your homeroom teacher for the next year. Now, I'm pretty sure you're all excited to be here, but let me give you a warning: these next four years will be tough. As future support crew members, the expectations placed on you by others will be extremely high. If you make even the simplest of errors when designing a hero's costume or weapons, it could result in the deaths of that hero and the people he or she were trying to save. It is because of this that we at U.A will be making sure that you won't be making those mistakes. This ain't middle school anymore, so the work you'll be given will be challenging, especially since in U.A, teachers are given permission to teach their class though any means they desire, as long as it's legal of course. Anyone not up for the challenge might as well drop out now, there's no reason for you to be here otherwise. Understood?"

"Yes sensei!" The class simultaneously shouted. Izuku smiled upon hearing his teacher's explanation, any doubts of him not receiving the necessary level of education needed to succeed having diminished.

"Good. For now, you guys can relax. In five minutes we have the entrance ceremony and all of you are going."

0000

"Our principle is an animal?" Mei whispered to Izuku as the opening ceremony started. When class 1-H arrived at the school's auditorium, they noticed they were the second to last class to arrive, meaning they didn't have to wait long for the ceremony to start. One of the hero classes seems to be missing, something which intrigued Izuku's curiosity until he remembered that teachers have free reign over what their classes do. Their homeroom teacher probably felt this ceremony was a waste of time and had already started putting them to work. Thankfully, it seems as Katsuki was in that specific class as Izuku couldn't find him anywhere. The ceremony started shortly after, with a white dog/bear/mouse creature making his way to the podium as one of the staff members introduced the creature as their principle.

"I'm just as confused as you are," Izuku answered truthfully. Even with all his knowledge on heroes, the boy couldn't recognize the principle. Due to the fact he was holding the position of principle, Izuku could only guess the animal had some sort of intelligence heightening quirk.

"Greetings everyone," the principle said, confirming Izuku's conclusion about his quirk. He wouldn't be speaking otherwise. "Now, I know what you all must be thinking. Am I a bear, a mouse, or a dog? In the end, none of that matters since I'm Nezu, the principle of U.A Academy. Before we get started, allow me to congratulate you all on a job well done. Each and every one of you have been accepted to the number one school in Japan. You should be proud of yourselves."

At this, the entire auditorium erupted in cheers, Izuku and Mei joining in on the fun. Once the applause died down, Nezu continued his speech. "I initially intended on the student who placed first on the hero admission exam to come up and give you all a speech, but seeing as neither he nor the rest of his class are present right now, we'll simply have to move on."

'Thank goodness,' Izuku thought to himself. He already knew Katsuki had scored the highest, the results being made live a week after the examinees received their own scores. Knowing Katsuki, he'd basically tell everyone that they were inferior to him and then brag about how 'awesome' he is.

"You all may have heard this from your homeroom teachers already, but U.A's mission is to prepare the next generation for the real world. As such, you will all be pushed to your limits. This doesn't apply only to the hero courses though. Whether you're an aspiring hero in the hero or general studies courses, someone who's in the business course dreaming of owning a large company, or if you're learning how to support the upcoming heroes through the support course, you will all be challenged. It is in U.A's motto after all, Plus Ultra: go beyond. You all got accepted to U.A, so there's no doubt you can do it. However, are you willing to put the time and energy needed to better yourselves? That is a question you must answer alone. U.A will give you all the tools to succeed, but whether you use them or not is up to you. Remember this as you go through your journey in U.A. Thank you for your time and remember: Plus Ultra."

"PLUS ULTRA!" The students shouted again, repeating the school's motto. For the third time today, Izuku couldn't help but smile.

After the opening ceremony, the rest of the day went by fast for Izuku. His class were introduced to their teachers, causing the boy to geek out much to the dismay of his pink haired friend, but as all the classes were the mandatory core classes, he couldn't count them as interesting. The last class however was different, it being Support Mechanics 101.

"We have to do what?!" A student asked as the class received their first assignment from Power Loader, the professor of the class, said class being held in the Support Development Room instead of a traditional classroom. It took Izuku a bit to calm Mei down, the lab being quadruple the size of hers and his combined.

"You heard me," the man replied. "The hero courses are to begin their training starting tomorrow and it's your job to make their first costumes. Each of the other classes are taking an assessment to gauge their abilities. The hero and general classes are doing a quirk assessment exam while those in the business course are required to take an exam testing their intelligence. As for you guys, how well you make these costumes will be used to determine your skill. Of course, I'll be looking them over and adding any adjustments this time around so you don't hurt anyone. In the future though, you'll be completely responsible for making the costumes and gear for the hero course, each of you being assigned an indivdual you'll be taking care of, so I need to know what I'm working with so I can prepare you for that moment. You have today and most of tomorrow to complete the costumes and the Support Development Room is open until 8, so you all have more than enough time to complete the task. If I were you though, I'd start now. I'll be around to answer any questions."

Finished with his speech, Power Loader picked up a stack of papers and began walking around the room to hand them out. When Izuku got his, he had to stop himself from scoffing. The costume he was assigned to make was going to be a cakewalk. Glancing at his friend, he noticed her staring intently at the paper, meaning the gears in her head were tuning fastly. "Hey, what type of costume did you get?"

"Well, the guy's name is Tenya Iida," the girl replied before showing him her paper. On it was his measurements, his quirk, and a sketch of his costume, it looking like a robot. "He wants something that can handle speeds reaching upto mach 5. He also wants his suit to accommodate the engines in his legs as a result of a quirk, but that's nothing I can't handle. This is going to be so easy."

Nodding, Izuku showed her his sheet. "I hear ya. I got a girl named Ochako Uraraka and all she wants is something which won't rip and a durable helmet."

"That's it?"

"Yeah."

"That's even more basic than mine."

"I know. This isn't a challenge at all. Heck, I'm actually going to give her helmet some extra features just so that I don't get bored."

"You know, that might not be a bad idea…"

The two then began to work on their costumes, making sure they got everything right. It would be embarrassing if they messed them up after complaining about the lack of a challenge the assignment brought them. Eventually, the final bell rang, signaling the end of the school day, causing their classmates to trinkle out of the room, each of them planning on continuing their work tomorrow. The two friends however decided to stay an extra hour, wanting to knock out the project as soon as possible. Mei still had her 'babies' she wanted to work on before the place closed after all. Eventually, the two finished and began comparing designs.

"And done," Izuku signed, placing the helmet he was working on down gently on the desk. "I ended up giving this thing infrared vision, night vision, bullet immunity, and the ability to allow her to breath underwater and in space for a short time. It kinda fits the whole spacesuit theme she has going on. Oh, and good luck trying to tear apart the costume. It's not going anywhere. What did you add to yours?"

"I made it able to survive going at a speed of mach 10," the girl said with a simple shrug. "It's also skid resistant and the mask allows him to breath underwater for a short time. He can survive about 500 meters into the ocean and the costume is light enough to allow him to swim in it with little problems. I would've added more, but I still have my babies you promised you'd help me take care of."

"I did?" Izuku questioned before getting a hurt glance from his friend. He didn't know if it was fake or not, but he wasn't willing to risk it. The girl knew how to play with his emotions better than his own mother. "Right, I did! Um, let me go get them real quick." Not wanting to do anything stupid, the boy quickly scurried out of the room, much to Mei's amusement.

"For someone as smart as Izuku, he can sure be an idiot at times."

0000

"Oi, Deku!"

'Fuck!'

Having grabbed all of Mei's inventions, Izuku was on his way back to the hero development lab, only to encounter his childhood bully. Even though Izuku knew the hero course ended two hours later than the other courses, he wasn't expecting to run into the blonde so soon. He was hoping he'd have a few days of peace before Katsuki would show his ugly head around.

"So you got in," the boy said in a mocking tone. "And here I thought U.A had standards. I guess that doesn't apply to the support course. Then again, the support course fits you. It's a place where people who aren't good enough to become heroes go to make themselves feel useful."

Izuku sighed. He really wasn't up to dealing with Katsuki today. He was about to walk away peacefully, until he heard something that came out of the boy's mouth which made him stop dead in his tracks.

"Just like your girlfriend."

Now, Izuku was fine with people insulting him, he didn't care. However, if anyone dared insult Mei or his mother, that wasn't something he could ignore. In addition, he was now at U.A training to become a hero, meaning he was no longer going to allow Katsuki to push him around or mock Mei. It was finally time for him to stand up for himself instead of ignoring the problem.

"...Honestly, I should be saying that about the hero course. They accepted you after all."

Katsuki glared at the genius. How dare he talk back to him! "What did you say?"

"For starters, the hero test is unfair. Blowing up robots, really? It's no wonder you got in, destruction's all you've ever been good at. If they did background checks, maybe they wouldn't have accepted you."

"What the fuck are you trying to say?!"

"What I'm saying is that you, Katsuki Bakugou, will make a horrible hero. You're arrogant, violent, and you pick on the weak. No one will ever admire you. And don't get me started on how many times you've broken the law. Seriously, you should be imprisoned since you've illegally used your quirk so much."

Katsuki snarled as he ran up to Izuku and grabbed him by his neck, his other hand firing off small explosions. "You better choose your next words wisely…"

"You don't scare me anymore," Izuku scoffed, removing his hand using the Mark Mini. "You're just a boy with anger issues. Even if I'm 'only' in the support course, even if I'm quirkless, I'll still become a better hero than you." Katsuki was about to strike Izuku, only for the boy to shake his head before nudging at a secuirty camera. "Trying to attack me when there's various security cameras around? Not very smart." Done with the conversation, Izuku began walking away. "You better watch out Katsuki, because I'm going to destroy this 'I'm the best' illusion you've set up."

Watching him go, Katsuki growled in anger. "How dare that fucking nerd…"
