My Hero Academia: Reborn As Denki Kaminari

Chapter 107

Title: Difference in Knowledge...

….

As he pointed his hand towards Shigaraki, he smirked. "Let's see the difference in our knowledge."

Wind was gathered in his hand and he created two mini storm tornadoes which each moved in the opposite direction of the other. This created something unnatural as a storm itself seemed to appear in Kaminari's hand.

<Lightning Bolt>

*BOOOM!*

In an instant, a real lightning bolt was shot towards Shigaraki, he couldn't even dodge due to the speed and was hit head-on. But the attack didn't seem too effective, only some burned skin which didn't take long to heal.

"Oy, what did you do to sensei?" Asked Shigaraki once more, his eyes now shadowed by his hair.

Kaminari smirked at it. "Well, that should be pretty obvious."

He was excited to fight currently because what he just used was a true lightning bolt. Something that held around 1 billion volts in it. 

'I knew it! Right now I just used a wind manipulation Quirk to create a lightning bolt through my knowledge of physics and my new Quirks.' He thought excitedly, once again, just like when he learned how to control the electric power outside of his body, he felt like the future had limitless power.

"Everyone! Buzz off, you are no match for the man in front of us right now. Go and fight some heroes. Have three High-End Nomu stay behind as cover." Said Shigaraki as he charged forward. Three of the ten Nomu also stayed with him, but they didn't interfere in the battle. The Nomu, though strong, every one of them would be countered by Kaminari's extreme speed. 

'Others Heroes would hesitate to kill even when fighting against Nomus. But Kaminari is different, he killed Twice and Dabi without a second thought.' Concluded Shigaraki, he knew that in this fight only one of them would walk alive today. "I will be the one to win. I am willing to admit to you Kaminari Denki, you are a terrifying creature. But even you won't be able to use your newfound Quirks better than me."

"You sure about that?" Asked Kaminari as the wind started picking up around him.

*CRUNCH!*

Suddenly Shigaraki's body twisted, the center of the twist being in his stomach as if a black hole had appeared in it. 

*cough!* He spits out a huge glob of blood, his organs immediately being filled with air and burst in an instant. This raptured his organs, causing disastrous internal damage, way more than any normal attack from the outside could have caused.

"This is the same with both of you. All For One also never really learned his new Quirks, he never trained them. To him, they were just tools that he could use and combine for stronger attack power." Explained Kaminari as his arms bulked up and rotated.

 <Rotating Arms> 

<Spear-like Limbs>

<Rivet Stab>

Kaminari combined the quirks all in his arms and they turned dark with red veins in them. 

*Fwish!*

In an instant he disappeared from Shigaraki's view and appeared behind the man, ready to bash his head in. But suddenly an array of knives aimed at Kaminari's vital points were thrown at him. He can easily handle them, but he decided to dodge just in case they had some unknown dangerous aspects to them. Kaminari knew how the weak fought, and he didn't want to fall prey to their attacks. Losing his life now because of some unfounded arrogance would be stupid in his opinion. 

'Unlike All For One and Shigaraki, I will never make their mistakes.' He concluded as he looked towards the one who threw the knife projectiles and saw someone he was very familiar with. "Oh~ Toga -chan, how nice of you to come here. Did you miss me? Wanna see another of your friends die now?"

Shigaraki immediately noticed the tone Kaminari was using to irrigate Toga who was angry, frustrated, and generally is not in a good mood. He knew just how much the girl hated the lightning hero. She had broken her wrists to escape the handcuffs, just so she could kill Kaminari by herself.

But the AFO successor also knew just how cruel Kaminari could be so he immediately rushed towards Toga, but the Hero also had done the same. 

Knowing that he couldn't match his opponent in speed, Shigaraki had activated one of the best Quirks in his possession <Overclock> the Quirk of a previous Hero who was a speed type, which now combined with Shigaraki's body had evolved into a whole other level of speed Quirk. This was Shigaraki's measure on how to fight Kaminari head-on. 

In that instant he sped up, the world froze around him. It seemed as if time itself had stopped. Though Kaminari too saw this and for the first time in his new life, someone could keep up with his maximum speed and run by his side. 

"Quite the nice quirk you have there," complimented Kaminari, not minding that there was a quirk that could keep with his speed. Why wasn't he bothered? It was because he already saw the quirk as his own. 

Punches, kicks, jabs, elbow hits, and many more moves were exchanged between the two of them. Though Kaminari had a slight advantage, Shigaraki was still able to keep up with his counterpart, mostly due to the regeneration. Though the latter didn't want to just fight his enemy, he had to save Toga from being killed. 

Shigaraki grimaced at this, usually, the heroes are the ones fighting in a disadvantageous situation where they don't even try to go for the kill. But Kaminari was different, he went for nothing else but a kill hit. There were no remorse, nor any mercy, only cold and logical killing hits. If he was like any other Hero, then Shigaraki would be right to assume that with new powers Kaminari wouldn't be able to defeat him, but sadly, he knew more about the villain than he knew about himself.

Every time Shigaraki tried to touch the ground with his hands, Kaminari would stop him and then shoot some <Finger Bone Bullets> at Toga who seemed to be frozen in time from their perspective. But AFO's successor shoots some lightning from his fingertips, stopping the lethal bone bullets and then shooting a beam-like energy out of his mouth and straight at his opponent.

Sadly for him though, Kaminari had already foreseen this and gone through the movements to dodge even before the attack came. Using a type of size manipulation Quirk, he made himself small like a kid, and due to that he also elongated his legs, making them taller. He looked like some kind of deformed person, but his speed increased, however slightly, it was enough to overtake Shigaraki and give him a chance for a true critical hit on Toga.

But as his claws were about to dig into Toga's flesh, Shigaraki saw this and unconsciously activated <Adrenaline> and <Pump Up> quirks which helped him for one split second surpass Kaminari's speed. Appearing before the teen himself and kicking him in the stomach.

*Baam!*

Kaminari's body flew away, but he still held a smile on his face. Immediately Shigaraki turned around in shock and saw that Toga had a spike through her head. He turned back towards his opponent, but Kaminari had already disappeared from his senses, he had just used the same technique as Toga to erase his presence. 

<Thunder Chop>

A karate chop lands on Shigaraki's unexpecting neck.

*Crack!*

Breaking the fragile bone in an instant and having the villain's body fly off like a rag doll, hitting the ground multiple times before it stopped. Suddenly Toga's dead body dissipates and shows that she was alive all along, Kaminari didn't have a chance to kill Toga previously, but he did now. Easily his hand cut through the air like a sword and Toga's head flew off her neck before she even knew what was going on.

Kaminari had used a <Hypnosis> Quirk, but instead of crudely using it to control his opponent, he used it to manipulate his opponent's perception and fear, causing Shigaraki's mind to create the illusion itself. He wasn't forcing anything, his opponent's mind did all of the work. Mind Manipulation Quirks can be used in many ways when they are in his possession.

Shigaraki saw the scene of Toga's death and an enraged roar came out of his throat, his look filled with absolute hate while gazing at his merciless opponent. He felt his heart shatter and a heavy feeling settle over it. He crouched down in emotional pain as his neck healed.

The villain's hands were both touching the ground now. "You took everything that I love from me, the people I considered comrades. So I will do the same to you."

Below his hand the earth itself starts cracking and turns gray as if it was dying. This signified that Shigaraki had started to use his <Decay> and was planning to destroy the whole U.A academy and the city beyond it together with everyone who lived there.

"DIE YOU BASTARD!!" Yelled out Shigaraki.

….

A/N: The way they both use their Quirks is totally different, All For One and similarly Shigaraki brute force their way throygh Quirk usage. But Kaminari comes up with ideas that create a definitive advantage in his favor. Kaminari can't allow a battle of pure power struggle to occur because he would lose to Shigaraki's superior physical abilities and natural healing. All For One was strong, but his body wasn't exactly the best and it was old on top of weakned by his life extension Quirk which allowed him to live over 100+ years. Anyway, this battle has a lot of unstable factors, especially since Kaminari did literally just get the new Quirks, though due to his general good Quirk knowledge he is using them pretty good...

P.S: <Overclock> is actually a canon Quirk that All For One stole, it literally makes one so fast that it seemed almost like time had come to a halt.
