I really don't know what else to say in these beginning parts in bold so I probably won't do them unless there is something I want to share. Anyways, enjoy!
Izuku woke up and got dressed before going to the kitchen and eating. He told his mom he was going to meet someone somewhere, before leaving to go to the place All Might told him to go to. When he got to a very trash-filled beach he saw two people. One was All Might's skinnier, weaker form. The other was a boy with blue eyes and blond hair.
I wonder who he is. Izuku thought as he walked towards them. He looks a little like all might. Maybe they're related?
Izuku saw that they were cleaning up trash on the beach. He approached them and was spotted by All might.
"Young Midoriya, you're here." All might said, causing the other boy to look at Izuku.
"Oh, is this the kid you were telling me about? The one that made the sword?" he asked.
"Yes. Midoriya, this is Mirio Togata. Mirio, this is Izuku Midoriya." All might told the two boys.
"It's nice to meet you, Mirio." Izuku said. I feel like I've seen him somewhere. Izuku thought.
"My quirk is permeation, which means I can phase through pretty much anything. What's yours? Mirio asked.
"Well, my quirk just appeared yesterday, so I don't really know yet." Izuku replied.
"Hmm. Well, we'll just have to find out how to activate it then." Mirio said." I'm sure you'll be able to use it. What exactly were you doing and feeling when you activated it?"
As the two of them talked to each other, All might watched and wondered how things would go for the two boys in the future. He knew his time as the number one hero was limited.
"Okay, if that won't work then close your eyes and try to imagine that you or someone else are in danger. Then try to use your powers." Mirio suggested.
Izuku tried that, and he felt a slight burning sensation on his arm, as he created not the sword, but a pair of giant red and gray hands that were much larger than his regular hands. " I did it, I mean I didn't create the sword, but I still used my powers!" Izuku said excitedly.
"Great!" Mirio told him "but, maybe if you can build two different things, there might be more!"
They trained in different ways and discovered one other build along with the sword. The build was a cannon attached to his arms that could either pick up an object, or chunk of something and fire it, or create a beam of red energy and fire it.
After training for some time, Izuku got a call from his mother telling him that it was time to see what his quirk was.
Once they got to the doctors office and took the test, they were unable to find anything that allowed him to create the machines, but they assumed that his quirk just worked differently than others and named his quirk Mechanic.
The next day, Izuku came back to the beach and trained. As well as the day after that, and the day after that and so on. Eventually the entire beach had been cleaned, and all the trash had been removed. Izuku also created a few new builds including a hover vehicle capable of turning the front into a battering ram, and boots capable of allowing Izuku to jump higher.
However, the sudden activation of both the Alpha nanite and Malware's powers attracted some unwanted attention.
Azmuth, the first thinker, looked into the frequencies, and was unable to discover how they were being created. The portal he had sent the two mechanical life forms into had closed already, but he decided to start building the machine as soon as possible to investegate, but he knew it would take a long amount of time.
Back in Izuku's dimension, he approached the doors of UA high school. As Izuku walked towards the doors he tripped and began to fall.
As fell he closed his eyes and braced himself for the impact, but it never came. He opened his eyes to discover he was floating. He stood up and a girl with short brown hair started to talk to him.
"Oh, sorry. I probably should've asked if I should've used my quirk first, but you probably didn't want to fall on such an important day. Anyways, my name is Ochako Uraraka." The girl said.
Izuku stumbled a bit in his response. "Oh, uh y-yeah I guess so."
"Well, good luck!" the girl said before entering the building.
Izuku went in after her. Once in the building, he and the other students took the written portion of the exam before Present mic explained the practical portion of the exam.
The pro hero was in the middle of explaining the three of the robot types (1, 2, and 3 pointers) when a blue haired teenager raised his hand.
"Sir, I have a question!" the teen informed the teacher.
"Hit me!" the voice hero replied.
"You have told us about only three different robot types," he began, "but on our sheet it shows four robot types. If this is an error on UA's part, then they should be ashamed. We expect better from the best hero school in Japan. And you in with the green hair," he said, pointing to Izuku," Stop muttering like that, as it is very distracting."
Izuku slowly lowered himself in his seat as present mic explained how the last robot was a zero pointer robot.
"You can beat the Zero pointer, but it's pointless because, well, it gives zero points." present mic finished before sending the students to the different sectors.
Izuku noticed the girl who helped him, and he decided to go and thank her. Before he could get to her however, the same teenager who told him to stop muttering put his hand on his shoulder and told him
"I can see that you're heading towards that girl. She's clearly focused on getting into this school. We all are. If you want to distract yourself and her by doing that, then you should just leave."
Izuku backed away after that, waiting for the countdown when present mic's voice erupted from the speakers.
"THERE ARE NO COUNTDOWNS IN REAL BATTLES, GO, GO, GO!" they heard.
Many students ran off immediately, like the blue haired boy, who had a speed quirk.
When Izuku heard this he built the hovercraft as soon as he fully processed what he had heard. He opened the front of the build to reveal the battering ram, and smashed through several robots. From doing that he got twenty-three points. He then disassembled the hovercraft and created the jet pack, and flew into the air to see the robots so he could shoot them from above, and did his best to form the energy cannon as he shot the robots from above.
Meanwhile in the viewing area, the pro heroes watched as students destroyed the robots.
"Anyone catch your eyes?" one asked.
"Actually, yes. One student seems to have the ability to create machines." another responded.
"Yes, they are all doing quite well. I suppose it's time to release the zero pointer then" another replied before pressing a large red button.
Izuku had obtained ninety-five points when the zero pointer was released. It was massive. It towered over most of the buildings. Most of the students ran away, including Izuku at first, but then he heard screaming.
He looked towards the robot, and underneath some rubble and saw the same girl who saved him from falling. He created the giant fists, accidentally causing the jet pack to collapse, and he flung himself at the robot, punching it in the face, but something strange happened in his panic.
Once he punched it, a black and red goop surrounded the robot, and then the black parts turned gray, before the robot crumbled into dust. He landed on the ground and freed the girl and was about to say something to her when present mic's voice erupted from the speakers once more.
"AAAAAAND, THE TEST IS OVER!" he said.
As Izuku began to walk out of the school and to his house, he thought about what had happened, and wondered how that happened. As soon as he reached his room, he collapsed into his bed, wondering if he made it.
