Don't own MHA, if I did I'll be a troll
Classes at UA where interesting. For one, class 1-A and class 1-B had different schedules so they wouldn't interact often. In the morning class 1-A had a normal non-heroic classes like math, history, and English. The most interesting part was that they were taught by heroes.
Izuku had to miss a few so Recovery Girl could actually teaching him about supporting others. "Are you taking note?" She said pointing to a diagram of a human.
"Do you know me?" Izuku laughed showing her his notebook for it.
"Good, now this part will only come up when you'll get your doctor." That just made Izuku sigh as he wrote it down.
After a quick lunch, they would began actual hero training. "I AM HERE," All Might said walking through the door "COMING THROUGH THE DOOR LIKE A HERO." This caused the class to get excited, Izuku and Izumi no exception looking like they would exploded.
"Welcome to the most important class here At UA High," he began standing at the front desk "think of this as Hero 101, where you will learn the basics of being a pro, and what it means to fight in the name of good. It's-."
"FIGHT TRAINING, YES" Katsuki smiled.
"Real combat," Izumi said nervously.
"But one of the keys of being a hero is," All Might said pressing a button on a remote he hid "looking good." The side of the wall opened up showing 21 cases. Each one holding a specially designed suit for each of the students. "Get suited up, then meet me at training ground beta," All Might said smiling.
"Yes sir," they all said. As they went to grab there suitcases, All Might stopped Izuku and Izumi to asked them something.
-a few weeks before UA began-
"So these our costumes," Izumi said holding up hers to get a better look at it. It was a deep green, with some light highlights. She had to remove the All-Might smile on the mask. The biggest difference between the two was that Izuku had a white mask green plus while Izumi just had a green one.
"Yep," Inko smiled "got my old costume designer to make yours. Though I did make a few modifications for your protection." Said protection was kevlar on the chest and some around the arms but was still allowed flexibility "don't worry about melting it, it's extremely heat resistance and light, but it won't stop high caliber bullets so be care about that."
"Thanks mom," Izuku said.
"Hey it no problem," Inko smiled getting up to hug both of her children "I want to make it up to up as much as possible for not telling you about who I was. I know you two aren't going to turn out like me, so be careful."

"It's good to see such young hero still have amazing style," All Might smiled. Hitoshi suit was more or less a carbon copy of Aizawa. He may not created the simplistic hero look, but the only thing that was unique was the mask and its special properties.
"Nice look Hitoshi," Izu said walking up to him. He got a good look at them, and it was obvious that they were a mixture of Izuku and Izumi, just with four arms.
"Izumi, I mean Izu," Hitoshi smiled "sorry it a little confusing. Why are you fused?"
"It's ok," Izu smiled "I'm fused so that I can train to hold this form longer, it'll suck if I defuse and it just leave Izuku and Izumi with a splitting headache."
"Today we will begin your combat training," All Might said with a smile.
"Excuse me Sir," Iida said in what looked like a suit of armor "this is the fake city from the entrance exam. Does this mean we will be practicing urban battles?"
"Not quite," All Might said "I will be moving you two steps ahead. Most villains fights you see on the news take place outside. However statistically speaking most villains fight will take place indoors. Think about it, villains won't plot to take over the war at a McDonald's. Most villains think smarter and plan in the shadows. For this exercise you will be split into teams of two. Good guys and bad guys. And fight two on two indoor battles."
"Isn't this a little advanced," questioned a frog like girl.
"The best type of training is what you learn on a battlefield," All Might answered "but remember, you are not punching a robot this time. You're dealing with real people."
"So you will be deciding who wins?" Asked a girl wearing far to little.
"How much can we hurt the other," asked Katsuki with a straight face.
"Are the losing team going to be expelled," asked Ochaco.
"How are going to be splitting us up," Iida asked.
"Does my cape look fabulous enough?" Asked a sparkling boy.
"I wasn't finished yet," All Might grunted "this is how it's going to go down. The villain will be guarding a bomb in their hideout. The heroes will foil their plans by capturing the villains or recover the bomb. The villain will succeed if they defeat the heroes or protecting their payload."
'Sounds like my dads favorite cheesy action movie,' Hitoshi thought.
"We will be deciding teams, via lots," All Might said taking out a box.
"Isn't their a better way to decide teams," Iida asked.
"Most hero team up are at random," Hitoshi said "but I'm wondering how we are going to split up Izuku and Izumi."
"I'm stay fused as long as possible," Izu said "even if I wasn't, splitting Izuku and Izumi up wouldn't be a good because their quirk requires to be near each other to function at 100%."
"Right, life is random and you two need to stick together practically," Iida said "I apologize for my rudeness."
"No sweat," All Might smiled "let's draw." It was pretty quick, Katsuki was paired up with Shoto, Ochaco was paired up with Kaminari, and so on. But to Hitoshi surprise he got Izu. "Now let's see who goes first," All Might smiled. He spun a digital wheel and it was Izu and Hitoshi as the villains vs Katsuki and Shoto as the heroes.
——
"Well we're in hot water," Hitoshi said a little worried. He patted the bomb a few time, it was made of papier-mâché and was very light. "We're going up a guy who quirk matches with personality and a guy who could solve globe-warming by refreezing the glaciers in a day. Got any ideas"
"Don't worry, we'll figure out a plan," Izu stretched their arms "do you have any equipment that could be useful? Your quirk doesn't seem very combative."
"My mask right here is a prototype," he explained "so far it can make my voice sound a little different." He gave a little example making his voice a little higher and a little lower. With higher almost sounding like Izumi and lower made him sound like Darth Vader.
"That sounds amazing," Izu smiled.
"Yeah, but I can only change it a little so far," Hitoshi sighed "that what I get for turning in my costume design in late."
"Well, it will still be useful even now," Izu smiled "how does you quirk work anyways?"
"If someone responds to any of my questions, I can make them do anything for a short period of time. But I can't make them tell the truth or make them use their quirk."
"That sounds like an amazing quirk," Izu said. They started to think up of a plan. Izu knew Katsuki would want to fight them, but Shoto was an unknown. It was a risky move, but Izu was going to be the first line of defense.
—Hero team—
"Hey Half and half," Katsuki barked "got a plan."
"Freeze the building," Shoto said bluntly.
"Ha, I don't think that'll work," Katsuki smiled "Izu has enough fire to probably melt your ice twice over, and when they're fused they're stronger than both Deku and Izumi."
"I thought they where Izuku and Izumi?"
"It a nickname, because Deku is a deku," Katsuki said "I'm going after Izu. You go after bed head."
"No," Shoto said.
"What!?" Katsuki barked at him.
"Hero team, you may enter the building," All Might said over the speaker.
Shoto put his handout to stop Katsuki, and slammed his foot down, freezing the building.
"You go after Shinso, I'll go after Izu," Shoto said walking into the icy building he jus made. Katsuki fallowed Shoto in anger and grunted at him.
"O-over kill much," Katsuki said slightly freezing as they walked through the building "I need to sweat to use my explosion!"
"It'll be over quickly," Shoto said about to turn left. But before he stepped in, a brilliant green flame erupted filling that side of the hallway, melting most of the ice in the process.
"Didn't think you'll freeze the entire building," Izu said turning to face them. Their arms engulfed in white and green flames.
"Eat this Izu," Katsuki said sending off an explosion at Izu who quickly ran down the hall firing some small ball at Katsuki and Shoto. Shoto just sent another wave of ice at Izu, who responded by making a wall of fire to stop it in its tracks.
"Stop freezing over," Katsuki angrily shivered. Katsuki hated winter months because it made it harder to use his quirk. The Izu twins never dealt with this problem because they could regulate their body temperature.
"Hitoshi I need you down here," Izu said over their earpiece "I'm fighting both Kachan and Shoto."
"A healthy lunch includes you daily count of explosions," Katsuki said send off a few at Izu. It actually hurt and they had to heal their injury. Shoto sent more ice and actually froze over their legs. But fire and ice will just make water. But that didn't do much as Shoto just sent more ice.
"Watch it Elsa!" Katsuki yelled "you almost got me."
"Then stay out of me way," Shoto said trying to overpower Izu fire with ice.
Hitoshi was rushing to Izu location, the bomb secured on the roof. He didn't low how to fight that well, but his quirk made up for that greatly. "Hey bomb boy, wanna fight?" He asked Katsuki.
"Hell no, I'm fighting Izu," he yelled not knowing he would be effected by his quirk. A moment later, he went into a trance like state.
"Come over here so I can wrap the tape around you," Hitoshi responded. Katsuki fallowed his orders quickly.
"One hero down," All Might said over the speaker.
"God damnit," Katsuki yelled in frustration.
"Shut up and move," Hitoshi said pushing him back "unless you want to become a bomb flavored popcycle." He drag a scream Katsuki out of the way to make sure neither got injured from the crossfire.
Izu was still fighting Shoto. Izu was already pushing their limit with the amount of energy they where spending. But Shoto wasn't any better. He was shivering with the amount of ice around him. Izu noticed "you need to stop Shoto," they said "your freezing up."
"No, I won't use it," Shoto yelled send more ice towards them. They put up a small wall of fire, make sure it wouldn't melt all the ice, just the one directly in front of Izu. Either Shoto would have to advance, or collapse with the amount of cold. But Izu had to make sure they wouldn't over so it and defuse.
"Todoroki, you need to stop send ice over and over," All Might said over the speakers "your going to hurt yourself."
"I'm fine," Shoto shivered. He slowly raised his hand, but Izu rushed and punched him back before any ice left his finger tips.
"Shoto please give up," Izu said worryingly "my fire can melt any amount of your ice. And you can't repeatedly launch ice at me unless you want frostbite."
"No, I won't use my fathers quirk." He send more Ice to Izu, nearly breaking the building in two. But it was all for not. A second later, he collapsed into Izu arms. They started to use their white fire in moderation to warm his body up and prevent any more injuries. The last thing Shoto saw before fainting was their green eyes.

After the match, Izu defused and a two medical bot helped carrying a passed out Shoto off to the nurse on a stretcher with Izuku fallowing to keep him warm and to begin more training with Recovery Girl.
"So anyone want to guess who was the MVP of this match," All Might smiled.
"If I had to make a guess, I'll say Shinso," Momo replied surprising Hitoshi "I mean no offense to Izu. But they could have stop Todroki easier that what they did. Shinso on the other hand quickly got his job as soon as possible with not real interaction. He also prioritize getting his, I guess hostage in this case, to safety."
"Correct," All Might smiled "even though Izu had a tougher fight, Shinso got the job done as quickly and as safely as possible and even saved young Bakugo."
"I don't think I deserve it," Hitoshi said modestly.
"Nah, come on man," Denki smiled putting his arm around his shoulder "you deserve it."
"Yeah, I mean Kacchan is not an easy opponent," Izumi smiled "I have had trouble against him."
"He got lucky," Katsuki said "if I knew how his quirk worked. I would have beaten him easily."
"Oh really?" Hitoshi gave a devilish smiled.
"Yes you insomniac bed head," Katsuki yelled. Then His eyes going into a trance.
"Cover your mouth until you leave school," Hitoshi order with Katsuki coving his mouth. A second later the entire class heard a muffled scream and a few of them giggling.
The rest of the matches went great. No terrible injuries like Shoto happened, most bruises and two people with bad stomach aches who where about to throw up.
"I over did it," Ochaco said before puking into a bucket. Izuku couldn't do much, as his white flame didn't heal things like that or it was slow enough to be not noticeable "don't you ever get quirk overuse."
She wiped her mouth and looked at Izuku, it was done in a very cute way. Izuku couldn't help but blush.
"Well, kinda," Izuku said nervously "it like fuel in an engine. B-ut I get it when I stay to long as Izu we get terrible headaches, which I can't heal."
'Do you want me to talk to her?' Izumi asked over the brain.
'I can do it,' Izuku said to Izumi.'
Later that day, Shoto woke up in the nurses office with a warm blanket over him. "Finally decided to wake up," Recovery Girl stated "you been out for almost the rest of the school day."
"I lost," Shoto said bluntly.
"Well, you nearly gave yourself frostbite," Recovery Girl smack his head with her cane "you're lucky we have Izuku or it might have been worse." Shoto sighed and got off the bed. "You should thank him the next time you see him."
"I'll, think about that," Shoto said walking out of the nurses office and headed back to the class to pick up his things.
In a bar, somewhere in a Komino, Yokohama. A 20 year old looked at the newspaper in disgust. "It's a complete joke," he placed his drink on the paper. It was about two things, Gravitrix returning and All Might teaching. He had a heard rumors about Gravitrix from other villains, especially from a Villain who now had a robotic arm. He mostly got that she was popular because of how much she focused on tearing down the tower of evil brick by brick.
But when he saw All Might, his blood boiled. "What do you think will happen," He asked the bartender before giving a deathly smile"when the symbol of peace and icon of vengeance, are finally killed?"
I'll probably add more at some point, or maybe not. I have been sitting on this for a little bit because I wanted to add more to the fight, but this is ok for now. I'm also revealing a little bit more about Inko past as a hero. Also FYI I might be posting another fanfic later.
