It had been two weeks since Izuku's Quirks had awakened, and Izuku had made changes to his life; he vowed never to be afraid again, and he was going to head on the road of improvement as his face was set into a determined expression. The boy walked into the apartment he shared with his mom.
"Hey, mom?" Izuku called.
"I'm in the kitchen, sweetie," Inko replied. Izuku walked into the kitchen, scratching his head and thinking about his first step.
"I've been thinking about taking these quirks seriously. I know little to nothing about them," Izuku stated, lighting a ball of blue cobalt energy and focusing on his other hand, the shiny black thing on his hand that acted as armor. He studied the cobalt-blue energy. "Odd it was Electric-blue before," he frowned.
"Maybe this energy Quirk has different properties," Inko theorized. "So, back to the matter at hand, maybe it would be better if you trained it so you could find out what your Quirks can do," she stated.
"Maybe I should enroll in some Martial Arts Dojo to learn self-discipline and build my mind and body," Izuku stated.
"That would be a good idea. Young Katsuki never learned any control or self-discipline, and I've seen the negative effect of his Quirk," Inko frowned.
"Well, now I have Quirks to defend myself," Izuku explained. "I'm not weak anymore," he stated.
"Hey," Inko said lightly, hitting him upside the head.
"Never say you're weak just because you didn't have a Quirk." "Just because someone has a Quirk doesn't make them a hero; sometimes, those people just grow to be arrogant, Selfish, narrowminded, and stubborn." "Those who use Quirks on the defenseless are the weak ones," she told him gently but firmly.
"But why did my Quirks activate so late? Most kids developed them younger?" Izuku questioned.
"Honestly, I don't know, but maybe fate was testing you, watching your character and seeing if you were worthy of having Quirks in the case when you do gain a Quirk, an extraordinary Quirk you'll only use it to protect and defend, I think the fates judged you worthy" Inko smiled "People with Quirks and who have known power their whole lives at times become blind and will lose respect for that power, a Quirkless person who has no power but knows the value of standing up for what's right and stick by their ideals and knows the value of true strength and courage never forget that" she explained.
"I just want to know why Dad isn't home too much. Is he disappointed that the Son of Firebreather is Quirkless?" Izuku asked.
"Whatever is going on in that man's head has nothing to do with you. I can't take much more of him," Inko stated sternly.
Weeks almost a month, Inko had signed her Son for a Dojo that teaches Martial arts; the Dojo was called Chozen's Tough and Tumble Academy. Izuku absorbed the techniques quickly, learning Karate, Muay Thai, Judo, and Aikido. Izuku learned quickly, thoroughly, and effectively; he met Itsuka Kendo. Her Quirk was the big Fist; she could get her hands to grow to an immense size. Izuku finally has a true friend.
Itsuka Introduced him to her two friends, Setsuna Tokage and Yui Kodai. Setsuna's Quirk: She calls it Lizard Tail Splitter. It enables her to split her body apart and still be in control of them, and it can even regenerate lost parts. Yui's Quirk: Size; her power enables her to shrink and return things to normal. The three became great friends.
Izuku also worked on his two Quirks, and Blue Energy had four functions: electric blue, Cobalt Blue, Sapphire Blue, and Navy blue. Electric Blue he called: Guardian Mode, the Sapphire: Assault Mode, Cobalt Blue: Assist Mode, and Navy Blue: Admiral Mode, which was for large-scale attacks; Izuku decided to call his Quirk: Supernatural Force cause of what it could do and it seemed to be unnatural and mysterious since his Quirk has never been heard of or seen and since he was a Marvel, Greek and Norse mythology, the Monster verse, Star Wars and Blade fanatic he made his moves named from the characters from his favorite comics and movies the second Quirk he called it: Haki which translated Ambition, he had three prospects of it.
The first was the shiny black substance that worked like armor Armament Haki; it could protect him and also increase his offense and defense capabilities by a significant margin; his second version of Haki, when aware of his surroundings and paying attention, could Sense everything around him, Izuku named it Observation Haki or a more specific term: Mantra, the third he could cast the energy inside his body outwards to either intimidate, scare, or knock them out he named it: Conquerors Haki or King's Will the ability to overpower the will of others.
As did his Quirks, Izuku grew more confident in his abilities and grew stronger physically, emotionally, and spiritually.
Time Skip Five years.
Izuku was now nine years old, and his body, along with Training in Martial Arts and his Quirks, Izuku's body sprouted some muscle and lost his baby fat; he had a rough year; his father came back and discovered while he didn't inherit his or his wife's Quirk, but instead, two unheard Quirks manifested in him, he didn't even look at Izuku or Inko and shut them out, started drinking let's say Hisashi crossed a line, he came in drunk throwing things around yelling and shouting after a heated exchange he hit Inko when she defended Izuku.
Izuku lost it; to put it mildly, he was furious, all the resentment he harbored for his father: from neglecting him and Inko, for leaving for months at a time, always going to bars or drinking in the apartment, the disappointment and disgust when he was Quirkless, finally punching his mother; Izuku had enough and snapped, unexpectedly something about Supernatural Force changed, and Hisashi was sent across the room, breaking through a wall to the kitchen crashing into a bunch of cabinets breaking them into pieces and shattering dishes with several teeth missing.
The two lost their tempers, and after an intense shouting and yelling exchange of anger-filled words, Hisashi kicked Izuku out, not needing a worthless son. Izuku countered by saying he would rather be weak and helpless than a drunken selfish son of a bitch like Hisashi, and he warned Hisashi if he ever hit Inko again or went near her, he would take him apart as he stormed out, and Inko went with him.
Two weeks later, Inko filed a restraining order, divorced Hisashi, and told him to stay away from her son, Izuku and Inko never saw him again. But after some help from his mom, Sensei returned to normal.
Seven years later, after the fiasco with his father, Izuku changed a lot; he trained harder and more seriously, graduated from his Old Dojo, and found another one that teaches Taekwondo, Hapkido, Shotokan Karate, Brazilian Jiu-Jitsu, Tai chi, and three deadly martial arts he would only use when defending against real-life situations: Krav Maga, Koppojutsu, and Kyokushin karate.
He learned to mix his different martial arts styles, and his body looked like an Olympic athlete's; he was well muscular and toned, and at 5ft 11 in, he was almost 6ft. His personality changed. He was serious, kind, well-mannered, funny, and helpful when someone needed a hand. He was confident and brave, and his Quirks had grown like him, very strong and versatile.
Supernatural Force and Haki had grown powerful over the years. Observation Haki can sense everything around him 100. If he focuses on increasing the range by 150 feet around him, Conqueror Haki could make people five times his size drawback in fright, render groups unconscious, and send them running from him. Still, The Conqueror's Haki was more potent than you first thought. He was group sparring, where one defends himself against multiple attackers by defending and engaging. He got enthralled with the thrill of the challenge, and he let out a loud battle cry as he moved forward as loud as he could. The King's Will flooded out throughout the Dojo and outside in a 50-foot radius in rippling waves of transparent energy. Everyone in that vicinity their eyes turned white and collapsed unconscious, but that was an accident. Hence, he trained his King's Will to get better control over it. Armament Haki could give him an insane boost to his physical abilities and cover it all over his body and clothes, and he even learned to combine his two Quirks.
Izuku, eventually, after years of training and hard work, had mastered Supernatural Force and Haki. He became a respectful young man and was very mature for his age, and he didn't get scared so much anymore unless it was snakes, the one thing he was afraid of. However, at least he doesn't scream and run away from them like he used to, but he still wouldn't go 10 yards from them, and he lost his muttering aloud. Nervous breakdown habits because training with Conqueror Haki and taking this Haki Quirk seriously made him steelier, had little to no fear, and was more serious.
Still, the effects of King's Will could also make him very stubborn and Proud; although there was nothing wrong with having pride, it couldn't overflow, so he always mediated and practiced Tai-chi. Martial Art kept him self-disciplined, calm, and collected so he didn't get full of himself; another bonus was that he didn't have his father anymore, which both Inko and Izuku were grateful for. Izuku solemnly vowed to strive to become a better man than Hisashi continually.
