Okay, I've gotten broad an I was going through My hero Academia archives and there is only one Fanfiction Kenchi history might disciple and this got me thinking what if Kenchi on his way to the dojo found a bet one Izuku and took him to the dojo to get patched up Akisame and Kensai and after talking with his mother Izuku made a chose to get strong. I mean look at the Elder. and What if doing so Izuku learns he had a dormant Quirk that was asleep and due to his training it awoke in his time of stress.
This will also by a harem story were there are some gender-bend Female Netio, Katsuki, and Shouto.
Chapter 2: The Demonic being that is a Cinmonroll and his masters
"I can't believe this is happening!" Izuku yelled as he ran with the very shuriken form of All Might toward the outside mark that is on fire where Izuku saw the sludge villain holding an ash blond girl hostage. 'Why is nobody helping her, she dying,' Izuku thought. "The heroes can get to the girl do to her using that Sludge guy making her Quirk," one random civilian said. Izuku hearing this ran toward her.
"He kid wait," Small Might said.
'Dam you Sludge fucker!' Katsuki internally shouted in her mind. as she tried to get the sludge villain off her. 'I'll make you play!'
"KATSUKI!" Izuku yelled as he ran toward her. 'Deku, stay away you get you self kill, why would you just trying to be a hero and be something else you Quirkless jerk,' Katsuki thought. Izuku then throws his yellow backpack at the sludge man's eyes and lined him. but he was still able to use Katsuki's Explosion Quirk on Izuku a real powerful one that covered him.
Katsuki was horrified at that moment but what happens next surprised her Izuku Tackled her out of the sludge and punched the Sludge man's face that caused an air vacuum that put on some of the flames to go out. Katsuki's biggest shock was seeing Izuku's new form he has darker tan skin, black sclera in his eyes and two pair of horn pop out of his forehead and wild hair on his face and body were blue demonic tribal markings tattoos and that was her biggest mistake looking at Izuku's abs do to his uniform being destroyed. "Holy mother of the White Buddha," She whispers to he self with a bloody nose.
"You piece of shit kid!" The Sludge man.
"Detroit Smash!" All Might yelled pouncing the Sludge man and causing the huge amount of air pressure to put out the rest of the fire with a hurricane punch which made it rain.
Izuku seeing everything was done when back to normal well almost everything the muscle was still there, "Izuku's has muscle, awhahaha~" a dark prevy part of Katsuki mind said making her get a red face.
After Izuku was getting a lecher on using his quirk, as well as Katsuki just for good measure now that the two middle school students ware done with the hold Sludge problem he left to go home to see his mother. As the two reach their crossroad Katsuki spoked. "Deku why the fucked did you lie to me," Katsuki said.
"If I did tell you would you believe me, The doctor lied to us turns out he was a con Doctor stealing Quirks of others kid and trying to make so bioweapons he could not use them so he thought he can make some money on it he tried but it failed big time when he tried to steal mine lucky me. But it only active when I trained with my, masters for the first time," Izuku said smiling at the first time seeing Kenichi fought a guy ten times bigger than him, the Akisame telling him you can be strong without a Quirk. He then remembers the training he went through to activate his Quirk that poor bear that was his first kill.
"Plus you saw it I was in control doesn't mean I found of lose it," Izuku said. "Now I have to get home and tell mom I'm okay and no one died," Izuku said.
"Shut it I didn't ask for your help!," Katsuki shouted.
"Okay Kaachan tell Mitsuki Obachan and Masaru Ojisan I said hi," Izuku said.
"Shut up do it your self," Katsuki said huffing as she left towards her home.
As he saw her left he counted to 30 seconds. "Okay she is gone now," Izuku said seeing the buff from of All Might walking.
"So what you talking about was your Quirk and you said you didn't name it." All Might now in his small might form.
"I was attacked by a giant black bear with about my Quirk. I was 5 at the time, and one of my Masters stop me from going on a rampage master my Quirk's battle lust took awhile to control I'm still in control it just I act differently more like my friend who just left, full of adrenaline and if I'm not careful I can kill someone that's why I never told anyone not even my teachers at school know I have a Quirk" Izuku said.
"Is it in the Quirk registered date base," Small Might said.
"Nope to reasons why 1 I fear that someone like that will try to hack the date beast to get it, and 2 I don't want people to try to kiss my butt," Izuku said. "You might if we talk and walk I have to see my mom and tell her I'm fine," he said as he walked toward his mother's home.
"You don't live with her," Small Might said.
"Yes and no, I started to live at a dojo that I go to on my first day of the second grand the place is called Ryozanpaku a place I met my strongest persona Alive and I mean it they have no Quirks they are all Quirkless but they can still take people with Quirks on and they do care if you have a Quirk they still teach you," Izuku said with a bright smiling.
"Ryozanpaku," All might said. He then remembers what his old teacher Nana told him about one of her old friends Hayato Furinji a Quirkless man that everyone fears even "Him" wouldn't be stupid enough to fight the ultimate superman.
"From an old man, he's about your buff size and he helped me train my Quirk then again he and everyone help name it made me draw it from a box now I have to put it down in the date base after this," Izuku said. "So why did you came to see me anyway," He asked.
"I wanted to thank you. If you didn't jump into the fight, I would have just been a worthless bystander. You made me remember who I really am, I saw myself in you when you ran in to save your girlfriend," He said.
"She not my girlfriend just a friend an old childhood friend who is a girl," Izuku said.
Elsewhere
"Why did you lie to me, you stupid Idiot, Baka, baka!" Katsuki yelled as she punches a plushly of Izuku, with rabbit ears.
Back with Izuku
"So I desired to make you, my Successor I deem you wroth to Inherit my Quik is your," All Might said. Izuku just looks at All might with a blank face. "Huh?" The young boy said.
"The tabloids guess that my power is super strength or invulnerability, but on TV, if the question is asked, I just dodge it with a funny joke, because the Symbol of Peace just had to be a natural-born hero. But I'm going to tell you a secret. I was not born with this power. It was passed on to me like a sacred torch." All Might spread his arms and a glowing image of him appeared in Izuku's mind.
"Wait, wait, wait! It's true that nobody knows how your quirk works, it's one of the world's greatest mysteries but the idea of passing on a quirk to others is mutter mutter mutter mutter..." Izuku was now just muttering over and over again. The word mutter was circling around him and All Might.
"Uh, it looks like you're overthinking this whole inheriting thing. Stop nerding out!" All Might exclaimed.
Three months later Dagobah beach
after Izuku and All Might spoked to the masters of Ryozanpaku Dojo Izuku get a new task to clean and practicing on using One for All, thanks to the years of training his body was perfect to use its power without any major drawback.
But doing this he was targetted by his towns mad inventor Mei Hatsume a girl with no personal space issue. and started a pack with the world's strongest demonic cinnamon roll and the Mad Inventor, Run for your live People what have I done. Foxsky packs his bags and ran for the hill. Cause after the first few months Mei made a robot that was the size of All Might that she calls All Bot. The Robot was programed with tons of fighting styles all over the inter next and ever heroes fighting styles.
And now that the beach clean Izuku was stretching his body help him was All Bot he looked like a Robotic version of All Might.
"So you want me to spare against All bot now that he full ready," Izuku said stretching his legs.
"Ehehehe, Yes I want to see my baby go all out he'll be my greatest helper and bodyguard," Mei said She is a very cute girl. She is a reasonably short girl with quite a mature build. She has salmon pink hair, which is generally shoulder-length, although it does vary, which is styled into thick dreadlocks and side-swept to her right. Her eyes are wide and sloped upwards with some notably long upper eyelashes, their irises yellow with a cross in the center, making them look somewhat like scope lenses.
"You have a good friend Izuku its to bad she doesn't go to your school." A man of above-average height and messy black hair. He is wearing, a white Yukato and dark blue hakama pants. A unique trait in his appearance is the dull and nearly colorless pupils of his eyes. "And She mans you a toy that you can train does it follow the basic law of the human body in sparing mode," Akisame asked the young inventor.
"Yes, but it also he an A.I. so he can think for himself but he won't kill anyone I made sure he has the heart of a can get a heroic license to stopping bad guys if he wants ain't that right my robot baby," Mei said talking to the Robotic Monster.
"So if I brake All Bot you won't be mad he can back up his Robo Soul like in your Computer," Izuku said now jumping in place get his blood pumping.
"No, but that depends on the damage Izu but I know how you can make my happy," She said.
"Okay. I'll be the referee when I say stop you stop All Bot your only aloud to dislocate bones don't worry them" Akisame said Izuku using D.O.D. and O.F.A. as his skin turned darker and the making appeared as well green lighting came out.
"Begin!" The Juto Master said. Izuku Ran toward the Robot same with All Bot ran at Izuku the two made contact with a Punching each other's fist to fist Izuku than ribbed A.B's wrist and give him a Juto toss toward and sandy ground but at mid-flip Izuku gave the robot a Muay Thai roundhouse Kick toward its robot ribs luckily Mei built All Bot with strong metal.
[Ost you say run]
But All Bot return the hit by giving Izuku a surprising kick to the face, sending Izuku flying across the beach tabling, Izuku used a street dance move that he learned from one of Kenichi's Friend. "Wow, Mei you really made a great piece of work here," Izuku said he then powered up by 5% more. "Full cowl, Time to see What he can really do, Ready to go Beyond," Izuku said as lighting sparked everywhere.
"Plus Ultra," All Bot said as the two started to rapidly Punch each other. Izuku stops at started to block and counter the Robotic rampage of fist that was heading towards his face and torso.
'I got to go even beyond my limits surpass those came before me, not as the next symbol of Pace and be more bring hope to people,' "Dragon Smash!" Izuku yelled as he broker throw the Robot's Guard and gave it an uppercut to its lower jaw hitting the Robot's block off for about 5 feet in the air, the force made Izuku was bleed from his knuckles,
"Winner Allbot Izuku you disqualified for killing your opponent,"
"I'm still alive," The disembody Robot said. as he when to pick up its head.
