MHA: The omni hero: Legion

Izuku looked through the glass windows, out to the school grounds as he walked towards the principal's office. UA was big, several acres in each direction, woods and urban centres and gyms and buildings, in the far distance, he saw a domed off building, he wondered what that was for. Eventually, he arrived at the principal's office on the third floor, in the centre of the building, he knocked and the principal beckoned him in.

The room was nice, with a big, wooden desk, with Nezu behind it, reading some papers, "come and sit with me, Midoriya"

So, Izuku sat down, looking nervously around, "why- why did you want to meet me, mr Nezu?"

"Well, you have done something I thought impossible until now, you got 195 out of 200 points on the theoretical exam. You see, my quirk makes me one of the if not the cleverest person on earth and the test are designed so that you could only get full marks if you have the same intelligence as me. 135 is already a super genius, the highest score I have seen before you was 170 but you, you got almost full marks. Yet when I checked your quirk registery, I found not an intelligence quirk but a quirk the likes of which the world hasn't seen in 300 years. Omnitrix, the same quirk as legion. I suspect you have some hyper intelligent transformation? Could you show me?"

"O- of corse", Izuku transformed into grey matter.

"Fascinating…", Nezu circled him, "and you have ten transformations? I have seen a few during your practical exam… one day you'll make a great hero. You won't mind to do a quick IQ test, would you?"

"Of course not", Izuku nodded.

…

"Fascinating… your scores are off the charts… this transformation has an iq comparable with my own. If you continue learning, you could very well surpass me one day. Hahahaha! How thrilling", Nezu laughed heartily, "I look forward to having you as our newest student… wait, right, I need to still give you your score for the practical exam. You got 62 villain points, which would be more than enough to get in on its own but you also went out of your way to save your fellow students, which can't go unrewarded in a hero school, so, we have awarded you 60 rescue points, making your total score 122, the top ranker of the entrance exam, five points short of 50 points over the second place"

"Really? I- I'm that good? I knew I would pass b- but first place? What score did Kacchan have?"

"Kacchan?"

"Erm- I- I mean Katsuki Bakugo, what was h- his score?", Izuku asked, his fingers tracing along the omnitrix.

"Ah, that would be the second place, 77 villain points, no hero points, quite the explosive personality too", he chuckled.

"I- I'm better than Kacchan? I have beaten Kacchan?", his face grew hot and he started shaking in excitement. Izuku jumped up in triumph, "take that Kacchan!"

"Is that a rivalry I smell?"

"N- not really. Kacchan was my friend, when we were young but as we got older and my quirk didn't show itself, he started bullying me but now- now, I have a quirk and I have just surpassed him", Izuku smiled.

"Well, I will keep my eye on him, if he misbehaves here, he will be punished. Rivalries are good and all but we won't excuse bullying", Nezu tapped the desk with his paws.

Izuku's heart filled with warmth, everything was falling right in place for him, his dream school, beating Kacchan and now, the support of the staff, "Thank you"

Back in middle school Kacchan was seething, he could see that much in the classroom and after hours, he cornered Izuku behind the school, "The fuck did you do, shitty deku?! You must've cheated! There is no way you could've outranked me without cheating! Tell me, how did you do it?! Did you bribe them?!"

"I- I-", Izuku was drawing blanks until he remembered that he wasn't the quirkless loser anymore, his hand absentmindedly traces the edges of the omnitrix as he found new vigor and confidence, "I got in on my own merit, accept it, Kacchan, you are no longer the top dog"

He walked past the stunned explosive blonde.

When he was a block away, he could hear Kacchan screaming, at the top of his lungs, "DAMN DEKU!!!" and all he could do was smirk. He would never belittle him again, that he vowed, Izuku was strong now, debatably stronger than Kacchan.

Soon, the first day of UA approached. Izuku had his uniform, his backpack and his school supplies.

"Are you nervous?" asked Ben, whom had visualised in his field of vision, only visible to himself.

"A bit, yeah but I know I can do this"

A few of the other people on the train looked at him for a few seconds, looking for the phone that he was talking over, when they didn't find it, they assumed it was his quirk. Technology and quirks sometimes worked hand in hand, that is why no one thought it weird that his 'quirk' manifested a watch. Of course, technology does go out of date after some time. There were some people out there who had VCR recorders in their chest, completely useless in modern times. The last time anyone used VCR in a normal setting was years before the emergence of quirks. Some said that technology quirks were one of the worst types of quirks, because you never knew when your quirk would become obsolete. There were technology quirks that never went out of date, like technopathy but those were rare. The most common quirks were enhancement and fire. Around 10% of people in japan had either an enhancement or fire quirk. Why those quirks were the most common, no one knew. Enhancement was easier to guess, there were a lot of ways to enhance the body, from just stronger muscles to iron organs or kinetic multipliers. Why fire though was a mystery.

"Just believe in yourself and you will make it far, you have the omnitrix, the most powerful weapon in the known universe", Ben encouraged him.

"Thanks, Ben"

He arrived at UA high and looked for his classroom. The layout was a bit confusing, so it took him a bit to find it but when he did, he strode in with confidence.

"How dare you lay your feet on the desk which your predecessors have used?", the blue haired student from the entrance exam scolded Kacchan.

"Where did you go to school and did they shove that stick up your arse or were you born with it?", Kacchan smirked sinisterly.

"I attended Soumei middle school and-"

"Soumei, eh? No wonder you are such an ass, that fancy private school spoiled ya?"

The blue haired student turned his head and saw Izuku, running up to him, "Hello, I am Tenya Iida from Soumei academy, you are the first ranker, right? I must admit, you are the superior student, you saw through the hidden objective of the entrance exam. You saved that girl whilst all I did was run away!", he chopped the air robotically.

"Nice to meet you, my name is-"

"If you are here to make friends, I suggest you go somewhere else", a homeless looking man in a sleeping bag said from behind him. He stepped out of the sleeping bag and introduced himself, "I am Shota Aizawa, I'll be your teacher. It took you twenty seconds to calm down, that is way too slow, I expect better of you. Now go put on these gym uniforms and meet me at the gym nearest to us"

"But what about orientation?" asked one of the girls, the brunette whom he had saved.

"We at UA pride ourselves in our freedom to teach however we see fit, if I say we are testing you, we are testing you, if I say jump, you ask 'how high?'. There is no use in that ceremony, we have better use of our time."

The students rushed to the changing rooms and got dressed into the gym uniforms. It was a feast for the eyes, so many hot people in one room. He blushed heavily whilst changing, his gaze lingering a bit too long at certain areas.

What he noticed was that he wasn't the only one looking the others up and down, a red haired classmate was staring at Kacchan. He couldn't fault him, Kacchan was hot. An arse but a hot arse at least. Another student was more focused on a wall, which he found odd, so, he looked closer, the purple haired boy was staring at a hole in the wall, blood dripping out of his nose, "what are you doing?"

"Someone drilled a hole here, into the girl's changing room, I'm only enjoying the view", he said, not looking away, "my god, I think I just saw a boob from the pink skinned one!"

Izuku gripped him by the shoulder and ripped him away from the hole, "I will tell Aizawa-sensei about this. If you know what is good for you, you will stop"

"spoilsport", he stuck out his tongue but continued changing into his gym clothes.

Izuku left before the others and walked to their teacher, "Aizawa sensei, I have something to report"

"Oh?"

"Yeah, the purple haired one, with the balls on his head? He was spying on the girls changing", he whispered. He didn't want the others to hear. Some of the girls were already there.

"Mineta? I will keep an eye on him, thank you for bringing this to our attention", Aizawa-sensei nodded. Slowly, the other students started filling in.

"Now, everyone, you have been doing standardized tests for all your life but until now, you weren't allowed to use your quirks, that is idiotic. Some day, they have to realise that not everyone is born equal. Midoriya, how far was your ball throw back in middle school?"

"42 meters"

"Now use your quirk", he threw a ball at him, which he caught, "only rule is you can't leave that circle over there"

Izuku nodded, activating the omnitrix, he cycled through the options, when he found it, four arms, he pressed down on the device and -with a green flash- he was gone and a 12 feet tall behemoth stood there, with four arms as wide as a torso. He gripped the ball in one of his arms and threw it. As it flew out of his hands, he clapped with all his might, creating shockwaves which further boosted the ball. The ball flew into the distance and, after a few seconds, Aizawa-sensei showed them his result, '850.24m'

"820 meters?", the red haired one asked, bewildered.

"DEKU!", Kacchan ran at him but was quickly contained by Aizawa's scarf, "why- can't I use my quirk?"

"Because I erased it, you won't attack another student outside of sparring on my watch", Aizawa said and then, Izuku knew why he seemed so familiar.

"You are eraserhead!"

"That I am", he freed Kacchan, "Don't do that again, I get terrible dry eye from using my quirk"

"We get to use our quirks as much as we want? This will be so fun!"

That seemed to have been the wrong thing to say, as Aizawa-sensei asked, "Fun? You think becoming a hero is all fun and games? Fine, if you think it is so much fun, how about we add a new rule? Whoever comes in last across all these tests gets expelled"

"Expelled? But we just got here? You can't just expel us, that isn't fair!"

"Fair? Are villain attacks fair? What about natural disasters? Terrorists? Nothing in the life of a hero is 'fair', get over it"

The challenges were quite easy for Izuku, most of the challenges were well suited for one of his aliens, XLR8 for the dash, four arms for the grip strength and so on. The only one where none of his aliens helped was the seated toe-touch and situps. Uraraka -the brown haired girl- was the only one to surpass him in the ball throw with a score of infinity, even Kacchan didn't get higher than him.

"Now, you already know your individual scores, so, let's pull up the overall performance", he clicked a button and a hologram appeared, showing everyone's scores. Izuku was at the top and at the bottom was… Minoru Mineta. The grape haired student was crying his eyes out but Aizawa-sensei said, as if walking about the weather, "by the way, I won't actually expel anyone, it was a tactical ruse to get you to try your hardest"

"I- I'm not expelled?"

"For now, no…", he had a creepy smile on his face.

They still got to catch the last few minutes of the orientation before they were let out for the day. Izuku was walking with Iida, when Uraraka came up to them, "hi, I'm Ochako Uraraka, you're Tenya Iida and you are Deku Midoriya right?"

"D- deku?"

"Yeah, that's what Bakugo called you, right? Didn't he go something like 'Damn you deku!'?"

"W- well Deku is a name to make fun of me, it means useless"

"How appalling!", Iida gasped.

"Oh- I kinda liked it, it sounds like Dekiru, 'you can do it', you know?"

"Never thought about it like that but that still doesn't make it okay, I'm Izuku, Izuku Midoriya"

"Well, thank you again, both for saving me from that zero pointer and for stopping Mineta peeping at us, Midoriya-kun", Uraraka said, rubbing her back of the head.

"You knew?"

"Yeah, Jiro's hearing is quite good, it's part of her quirk, she heard you scolding Mineta, thank you"

"N- no problem"
