Long time no see for this fic, am I right?

Power loader nodded to 1-H as he entered the classroom.

Placing a few stacks of paper on the desk, he got to work taking the roll. After that, he pushed a few buttons on the workbench, and a projector screen came down from the roof.

He coughed into his hand to gather everyone's attention. "Morning class. Hope you all had a good orientation, although, with the lengths of Nezu's speeches in mind, you probably didn't."

He clicked on his mouse a few times, bringing up a camera feed of students in brightly coloured costumes. "Today, we will be watching class 1-A's heroics class. I have been notified that they will be doing Quirk Demonstrations and Equipment Tests. Each of you will select 2 people and create basic designs for an item that could be used by your chosen student."

Mei was bouncing up and down at this. While this was basically what she had been doing in the workshop before she came to the classroom, she would suck it up and get through this class so she could go back to said workshop.

She looked over to her right to see Izuku's assigned desk empty as the first trial started. While she was an excellent engineer (if she said so herself), she didn't have the same capacity for Quirk analysis that Izuku had.

He was a wiz at it! Just like she was a wiz at gadgetry! That's one of the reasons they meshed so well! They covered each other's flaws! So why wasn't he in class! She huffed in disappointment.

He was probably off messing with someone or something. Sometimes she felt like Izuku was actually Nezu's son with how much he acted like him.

She ended up picking 2 girls, named Tsuyu Asui and Eiko Kirishima. Asui's Quirk was fairly straightforward, her file naming it 'Frog'. But Eiko's… was a bit more complicated, something Mei was excited for!

Her Quirk was called 'Draconic Strength', a Quirk that gave her red, dragon-like mutations such as horns, a tail, and red wings that sprouted from her shoulder blades. On top of that, she had the ability to harden her skin and had huge amounts of super strength.

She knew she was going to have a lot of fun designing gadgets and items for the girls to use, especially Kirishima. Draconic Strength was a Quirk that lent itself to both offence and defence, making it hard to build gadgets for, but Mei enjoyed a challenge. She had never seen such a versatile Quirk before!

It was almost like she had multiple!

Izuku was trying really hard to stop himself from laughing.

All Might had agreed to let him test something during this class. Sure, it took a little convincing. But after Izuku brought up that All Might could use this time to both rest, and start learning about how to properly teach a class like this, he agreed to it.

Izuku was testing a fairly recent invention, something he hadn't had a chance to use yet. It utilised Kori Kemonai's Quirk 'Hard Light' to create illusions around a person's body, or in this case, Izuku's Iron Suit.

He had to put All Might's muscle form through a 3D scan for it to work properly, but that was easy enough. Couple that with a voice modulation program run by MUM 2.0, and it was actually rather easy to trick the other students.

He was going through some information with All Might, who was watching a live feed from the suits HUD. "So, Mr All Might. I had a look at your original lesson plan. I have to say I'm a little disappointed."

He continued before All Might could speak up. "I know you have never been put in a teaching situation before, so it's understandable that you would be inexperienced, but this lesson plan is missing a lot of necessary things."

He looked over at the archway, not seeing any students yet. He nodded to himself. "We still have time, so grab a pen and paper." He waited a moment before he got confirmation from All Might that he had grabbed some.

"Good. Now, the exercise is simple enough, but I think we are going to push back the 2 on 2 fights until at least tomorrow. Throwing a bunch of teenagers into an arena with new gadgets and permission to use their Quirk will end poorly, around 95% of the time"

He heard the soft scratching of a pen on paper and nodded. "I think that today we should focus on testing costumes and gadgets, allowing the students to get familiar with their gear before having to fight with it."

There was a cough from the other end of the call. "Uh… Midoriya, wouldn't it be better to give them a lesson on how unpredictable heroics can be? They might not always get the chance to learn how to use the items they acquire."

Izuku sighed. "While that is true, this is their first lesson. We can't expect any of them to be experienced in anything more than martial arts tournaments, with the exception of Todoroki and maybe Yaoyorozu."

He checked for the students again, but saw none yet. What was taking them so long? "And while you are correct in the fact that sometimes you can't choose what equipment you use as a hero, from my observations, it is clear that these times are a rarity. Proper training with your equipment is essential for a good hero, in my opinion."

There was a sigh from All Might. "I guess you're right. I've never really been one for support gear or complicated costumes myself, so I will take your word for this as both a designer and Nezu's personal student."

Izuku chuckled. "How gracious of you, Mr. All Might." He noticed the sounds of chatting and footsteps, signalling that the students were almost there. "Alright, I'm going to mute you now, listen in and take notes. There will be a test on this."

"Of course. I'm in your care Midoriya."

Izuku clapped as the students started to appear from the dark tunnel. He didn't know why it was so dark. Probably for dramatic effect.

"WELL WELL WELL! YOU ALL LOOK LIKE PROPER HEROS! HOW ABOUT WE GET STARTED!"

Katsuki could tell something was up.

Now that he had gotten over the initial hype of seeing All Might face-to-face, it seemed blatantly obvious to the massive All Might super-fan.

All Might's posture was a little off, slightly more hunched over than usual. And his voice was coming from lower than where his mouth was. Katsuki didn't know what was happening, but what he did know…

Was that this wasn't All Might.

He listened to the fake prattle on about their equipment and how they would be spending today learning how to use their gear safely, before moving onto more combat-focused exercises later in the week.

He huffed in annoyance at that. He had been looking forward to doing some fighting, as it had been a while since he had a proper fight, and now he was going to have to wait.

He spared a glance down at the gauntlets that Izuku had made for him, remembering how Izuku had vetoed the original plan of having one big container for one big shot, and replacing them for four rotating containers, giving him four, small-to-medium shots.

He had begrudgingly accepted Izuku's point about 'not needing enough stored up nitroglycerin to level a building' but he maintained that the cool factor itself warranted its construction.

Izuku disagreed.

He huffed, understanding the fake All Might's point. He would have to corner the fake while others were training, just in case, it wasn't some villain. He highly doubted it was a villain, due to UA's security, but it was always better safe than sorry.

It took a while for Katsuki to be able to get the fake All Might alone, but was able to make an excuse to get him out of everyone else sight when he blew up one of the testing area walls with one of his gauntlets.

"YOUNG BAKUGOU! HOW MAY I HELP YOU?"

Katsuki immediately lunged at the fake, setting off a set of smaller, quieter explosions. "You're not All Might, I can tell, so who the fuck are you?" He didn't yell, not wanting to alert Dumb-Ears or Squidward to what was going on.

There was a flicker of light, and All Might disappeared, leaving only a black and gold suit of armour. Katsuki recognised the logo on the front. "Wow, Kachaan. I really thought this would fool everyone! What gave it away?"

Katsuki had to stop himself from facepalming. Of course it was Izuku. He was probably using this time to test out some device, probably whatever he used to create the illusion of All Might.

"Well, your stance was wrong, the voice was coming from his chest, your laugh was a little off- wait no! That's not the point! What the fuck are you doing Izuku?" He growled out the last bit, but his tension was already ebbing away.

Izuku just chuckled as the face mask to the suit opened. "An experiment! I'm also helping All Might learn how to do these lessons properly! Say hi All Might!" There was a crackling noise, and then a confused murmur.

"Oh, uh, yes! Hello Young Bakugou! Midoriya was helping me get acquainted with some things! Sorry for the deception my boy!"

Bakugou just dumbly waved, not realising the man couldn't see him. Izuku just laughed quietly. "I'm sure he'll be fine All Might! Now! Back to your practise Kachaan! Don't want anyone getting suspicious!"

Katsuki grumbled in agreement, too happy about having talked to All Might (note: didn't actually talk) to complain.

The rest of the class went smoothly.

Izuku, with his disguise back up, went around and gave suggestions and ideas for how people could use their Quirks and gear, as well as showing a few people how to use the tricker gadgets. (He noticed Kirishima seemed extra familiar with All Might and took note to look into that further.)

He was amazed at the raw power that a few students had, Todoroki's ability to create enough ice to make a glacier near-instantly, Momo and Uraraka's physics breaking Quirks, Iida's speed, Sato's strength, etc.

But none impressed him more than Eiko Kirishima, who was a fucking dragon-girl. Now, Izuku would deny being a weeb, on account of being Japanese already, but he had watched his fair share of anime over his life, so a real-life dragon-girl was a really cool thing to see.

But even cooler than the fact that she was a literal dragon girl was the raw power she seemed to possess. The deep red, fire-like cloak of energy she used during the training sessions, something he had learned she called her Draconic Veil, gave her hardened skin, as well as super strength and speed.

If he hadn't predicted that Mei had already selected her for gadgets and support items, he would have scooped her up himself.

He got a few new scans and notes on a bunch of peoples' Quirks, noting that Hitoshi's Quirk relied on what basically amounted to a biological speaker in his throat instead of regular vocal cords, which was probably the cause of his slightly raspy voice.

But it made it harder for Izuku, as it meant Hitoshi's Quirk was a Mutative Emitter, one of the hardest types to replicate with technology, usually requiring a special mucus or growth to function in the user.

(Now that he thought about it, maybe not being able to make a mind control device was a good thing)

He got some odd readings off of Uraraka's Quirk, making him rethink what it actually was. Because of his excitement during the Quirk test Aizawa did, he assumed that she was making objects Graviton-phobic, but with closer study, it seemed that she wasn't sending them away, just changing how they affected said object.

He would have to look into that further.

He had gotten some good scans of Momo's 'creation' Quirk, but he doubted it would be enough to recreate with technology just yet. He would have to bring her into the lab one day and get some in-depth scans done.

All in all, he was really enjoying himself so far! He had dropped the illusion at the end of the class and surprised everyone with his appearance, and had hounded him with questions, with the exception of Kachaan.

It had gone fairly well, and Izuku was looking forward to working with 1-A more. He reached his workshop, took off his iron suit, placing it in its charger, and headed off towards his dorms. He hadn't seen Mei all day and was getting restless. (ha!)

He wanted cuddles, and he wanted them yesterday.

And from the way Mei glomped him the moment he entered the building, she felt the same.
