The Abomination Quirk

by SamuelthegreatOO

Izuku Midoriya has been bullied for being Quirkless. After all, his doctor's report shows an extra toe joint. But he knows better. Kaachan knows better. After all, when you have four tendrils that can sprout out of your back and digest a man in seconds, that's probably a Quirk. Rated M for sayings and graphic death. NO YAOI!

13. Chapter 13

AN: And once again messes up my chapter.

Not human. Those two simple words were echoing around Izuku's head. Not human. "I'm sorry about this Izuku. I couldn't come to any sort of different conclusion. Not only are you not human, but you're not even an animal like Nezu. You're a viral mass." Not human. "That's impossible! A mass of viruses can't be intelligent! Nezu may be an intelligent animal but the idea of a virus, or even a group of viruses being intelligent is absurd!" Toshinori protested. Recovery Girl shook her head. "His prior blood test checked out as human. My theory is that during the USJ incident- that's what the media is calling it- Izuku's Quirk evolved past the point of no return. I thought it was just a mutant Quirk… but this is something else entirely."

Not human. "Still… this isn't possible…" Toshinori stated. "Don't you think I know that?! Aizawa told me that he suspected something because the robots were only supposed to go after humans in a short range based on DNA scans! I told him it had to be a glitch! I told myself that after the first test. And then I repeated that after the second test. And then I said that after the third test, and the fourth one as well! However, I had to face the facts after the fifth test. It wasn't a glitch. Izuku is, officially, not human." Not human.

"Bullshit," a voice rang out. Toshinori and Recovery Girl turned towards the sound and saw Shinso. "Hey! What are you doing here?!" Recovery Girl demanded. "I was told by Aizawa-Sensei to come here, and he mentioned that Yagi-Sensei was also here, so I'd be able to say goodbye as well as get a checkup."

"Whatever do you mean?" Toshinori asked. Shinso beamed a smile. "I'm going to class 1-A!" He exclaimed. Yagi clapped at that. "Well done young Shinso! I told you your Quirk was useful in heroics!"

"Indeed. I've heard that your boss, All Might, teaches Heroics. I'll suggest a raise."

"T-there's no need for that…" Toshinori stammered. Recovery Girl had to stifle a chuckle. "Oh, but there is. The General Course loves your lessons. Also, what was that about Midoriya not being human?" Izuku was just sitting there, the words 'Not human' still bouncing around his head. He wasn't really paying attention to anything. "Oh… well… are you sure you want to know?" Recovery Girl asked. "Yes, because it's bullshit of the highest caliber." By now, Izuku was beginning to regain focus. "He doesn't even have DNA anymore. It's all viral RNA." Recovery Girl answered, handing him the photos. "Recovery Girl! As a doctor you of all people should know how important patient confidentiality is!" Yagi scolded. Before she could answer, Shinso put down the files.

"I see. Izuku?" Izuku lifted his head. "Y-yeah?" And then his eyes went white. Yagi gasped. "What is is Toshinori?" Recovery Girl asked. "T-that's the expression of someone whenever Shino's brainwashing them, and it only works on humans!"

"Izuku, show me what you can do with your Quir-" he was cut off when Recovery Girl tackled him before he could finish. "Don't!" she shouted. Shinso was rather shook up, but he nodded. "Ok then… Izuku, repeat after me; 'All Might is the worst human being to ever live.'" Recovery Girl snorted. 'He'd never say that.' She thought. "All Might is the worst human being to ever live," Izuku monotoned.

All For One suddenly felt a rush of giddiness run over him, and had no idea where it came from.

"W-why did you make him say that?" Yagi asked, a little insulted. "From what I've heard from the rumor mill, Izuku here is a die-hard All Might fanboy, so to prove to you he was under my control, I had him do the one thing he'd never do." Izuku was released from it, and Recovery Girl nodded. "I thought he might just be going along with it in a vague hope that he was human, but apparently that's not the case." Izuku just stared. "Congratulations, Izuku Midoriya. In spite of the fact that you don't have DNA, you're still considered human." Recovery girl stated, wondering how the hell that was possible.

"H-how?" he stammered. "Young Shinso's Quirk only affects humans. Nezu proved that. Therefore, since you're affected by it, you're still human, no matter what the DNA results show!" Yagi declared, a smile on his face. Izuku then lied down on the ground. "What are you-" Shinso began to ask, before Izuku wailed, the force of the tears blowing a hole in the roof and sending him ten feet into the ground. "Holy fuck." was all Shinso could say.

After Izuku leapt out of the hole and Shinso had left, something came to Izuku's mind. "Oh, All Might! I just remembered! When I was brainwashed, I had a vision. I saw eight or nine figures. During the brainwashing, it was like my mind was filled with fog. They drove it away and allowed One For All to build up in my fingers. What if… what if the ones who have passed One For All down the line still exist within it?" He finished. He looked up and saw the frail form of his sensei shaking.

"T-that's scary… what the heck?!" That shocked Izuku. "I thought you might have known about it!" Izuku responded. "I saw something like that when I was younger, as well." Toshinori said. "It means you're getting a better grasp at One For All."

"What do you mean?" Izuku asked. "I think it's a trace of themselves that they left behind when they passed One For All down. They can't interfere, and you can't bother them. They didn't break your brainwashing. You saw the vision, and your strong emotions helped overcome it." Izuku sat down and began rubbing his head. "That explanation wasn't satisfying at all…" he muttered. "Don't get so hung up on it!" Yagi shouted. "After all, you need to see who you're fighting next!" He demanded. "Oh right! Thanks!" Izuku shouted as he left the Nurse's Office.

'So Midoriya won, huh?' Shoto thought to himself as he walked to his waiting area, only to run into Endeavor. "You're in my way." he flatly stated. "You're acting disgracefully, boy." The #2 said with zero warmth. Todoroki ignored him. "If you used your left side as well, you would've won both the cavalry battle and obstacle race," Endeavor stated. Todoroki ignored him. "Stop this rebellious behavior. I won't allow you to corrupt your duty. You were created to surpass All Might. Do you understand?" Todoroki stopped. "That's all you see me as, huh? I'll win using only Mom's power. I'll never touch yours," Shoto snarled. Endeavor laughed. "You'll reach your limit eventually, and then you'll finally work properly."

Izuku casually walked towards where the rest of his class was sitting. "Hey Deku!" Uraraka waved. "Nice work!" "We saved a seat for you!" Iida stated. "Thanks!" he said. He then walked and sat down.

The next match was Todoroki vs Sero. It went about as well for Sero as Izuku thought it would. However, he was still in shock at the sheer size of the glacier Todoroki created! Also it was right next to him. The creation of it shook the whole stadium! Sero had been immobilized, so he lost.

It was a while before the next match could go forward, as the ice had to be melted and then the stage had to dry. And then it was Kaminari vs Ibara. The battle was delayed for a few minutes as she spoke in a calm tone, criticizing Mic for calling her an 'assassin'. Izuku was impressed. And after Mic stammered as 'start', Kaminari decided to speak. "Hey, when this is over, do you wanna grab a bite to eat?" he asked her. "And I'll comfort you about your loss, because this match will be over in an instant!" he declared, using all of his electricity at once, frying his brain. Ibara just turned around and created a wall of vines, and then sent several out as soon as the voltage stopped. They grabbed the dumbfounded Kaminari and immobilized him. "And like Kaminari declared, the match was over in an instant! It just wasn't in the way he imagined!" Mic shouted.

"Oh dear, did a Class A member lose to a class B member?" Monoma mocked. Oh the shame! After all you're all supposed to be better than us-" He was cut off when another class B student chopped the back of his neck. "Sorry about that," she cheerfully stated, waving. 'What the heck was that?' half of Class A thought simultaneously. And then they heard a certain thing.

"Kaminari's Quirk is supposed to be really strong, but Shiozaki placed fourth in the entrance exam-why wasn't she in Class A?- but her Quirk is Vines, huh? It's a lot like Kamui Wood's Quirk. Could they be related? Also, binding type Quirks are really strong, and I've hardly ever seen anyone break out of them. Also the way she acted, along with her hand gestures, made it look like she is a Christian. Her hair had a pattern that looked like a crown of thorns- possibly a reference to Jesus? That religion isn't very common in Japan, so where'd she get it from? Is there an American in Class B? But I digress. It'd be impossible to get close while avoiding all of those vines, so most people would have to either tear them off or get close with brute force. Could I consume the vines? And if so, would she be able to separate them fast enough? I can't risk it. She'd probably go for someone's hands first to prevent that though, so there's that…"

"You just finished your match and you're already thinking of ways to beat her?" Uraraka asked. 'Did he even breath there?' she wondered. "OH! Oh, I'm so-sorry… it's just that this is kind of my hobby…" he stammered. Bakugou chuckled. "It's more than a hobby. It's his damn lifestyle."

"Kacchan!" Izuku whined. "He loves seeing Quirks in action, and his dad encouraged him to write about them," Bakugou explained. "Oh right! I've been putting these together for Class A as well!" Izuku said, holding a page up to Uraraka. "See? It's your Zero Gravity!" She stared at it, wide-eyed, before chuckling. "Deku, you've been amazing since we've met, but this is just reaffirming it!"

"Huh?" Izuku asked. And then Mic saved him from embarrassment. "All right! It's time for the fourth match! It's Tenya Iida versus Mei Hatsume!" To everyone's shock, Iida was equipped with gear suited for his Quirk and Mei had made it! 'He's too trusting' were the thoughts of the entire class. They were expecting it to sabotage Iida, but they were wrong. Mei had used Iida as a walking advertisement! After ten minutes, she casually walked out of the match, smiling. "Uhh, Mei Hatsume is out of bounds… Iida wins…?" Midnight got out, obviously confused.

The next match was Yuga versus Mina. Mina used her acid to slide around and avoid Yuga's naval lasers. This led to him eventually being unable to use any more, and Mina knocked him out, advancing to the next round.

The next match was Momo versus Fumikage. The crow-headed boy used Dark Shadow to quickly push the tall girl out of bounds.

The next match was between Karishma and Tetsutetsu. Karishma managed to eke out a victory and advance, but that was after a draw. He had to win an arm-wrestling contest!

The final match of the first round was Bakugou versus Uraraka. Here, the match was close. However, Bakugou managed to pull out a win, in spite of Uraraka taking several pages out of Izuku's notebook and thinking on her feet. He wasn't mean about it. It took several minutes, but Uraraka finally passed out. Before she did, however, Katsuki decided to say something to her. "You were a strong opponent, and a quick-thinking one at that. You'll go far. Don't see this merely as a defeat. See it as a challenge to yourself. Look at it and think 'I managed to get that far. How far could I go if I pushed myself even further?' Never give up, Uraraka." She passed out, but everyone was shocked at how kind the explosive blond was.

After that, it was time for Izuku to fight Todoroki. As he walked towards the stage, he saw the number two hero walk right in front of him. He froze in shock. "Endeavor!?" He shrieked. "Oh. It's you. I've been looking for you," the man grumbled. "W-what are you doing here?" Izuku stuttered. "I watched your fight. And I have access to the reports on the USJ incident." That made Izuku shiver. "You have an… interesting Quirk. However…" Izuku was trying to get around him when a giant hand grabbed him and brought him to the Number Two hero's face.

"You won't win. I won't let you. You see, it's important for it to surpass All Might, and you'll be an excellent stepping stone." Izuku was shaking in fear. "Also… as I said, I have access to the reports on USJ. If you break it before its job is done I'll destroy everything you hold dear."

"Y-you can't! That's illegal!" Izuku stammered. Endeavor chuckled. "Illegal? I am the law. If I say something's legal, it's legal. Now, your mother's name was… Inko, right?" Izuku snarled at the not so thinly veiled threat. "Don't touch her!"

The Number Two chuckled. "Oh, have I hit a nerve? Well, you better not harm him, or she'll have an accident." The way he said that sent shivers up Izuku's spine. Endeavor dropped Izuku. "Go. Leave my sight, monster," he growled. Izuku watched the man turn the corner and leave, before walking toward the exit.

"The first match of the second round is gonna be a big one!" Mic shouted. "On one side, it's the student who could probably literally freeze hell over, Shoto Todoroki! And on the other side, it's the student just bursting with surprises! It's Izuku Midoriya!" The two faced each other. "So, you're here." Todoroki stated. "Todoroki…" Izuku replied. Up in the stands, Iida turned to Fumikage. "Tokoyami, what do you think of this match?"

"It depend on whether Midoriya gets close to Todoroki or not. It also depends on how far Midoriya is willing to go." Uraraka nodded. "Yeah. What's Deku going to do about that ice?" Uraraka asked. "Those claws of his may be able to cut through it… I think." Katsuki chimed in.

In the League of Villains base, All For One was watching intently. 'Now then, what will you do, Izuku?' he thought, before realising what Izuku called his opponent. "I still can't believe Endeavor had a kid." he grumbled.

At Izuku's apartment, Inko had gone through so many tissues they were about two feet deep. "Izuku…" she bawled, using yet another tissue.

"AND… STAAAARRRRTTTTTT!" Mic shouted. Almost immediately Shoto let loose a barrage of ice from his foot. As the wall rushed towards him, Izuku summoned One For All into one of his fingers. "SMASH!" he cried, destroying the wall of ice, along with his finger. Todoroki had to make a wall of ice behind him to prevent himself from being blown away. "Just as I thought… you were willing to injure yourself to negate an attack…" Todoroki muttured. He then fired off another attack. "SMASH!" Izuku shouted, repeating the trick again. 'Ok, it'll be about a minute until I can use that finger again.' Izuku thought to himself. 'Given the amount of time Todoroki has to pause due to the wind, it should be around ten seconds until he can fire off another ice blast. That means I can keep this up almost indefinitely since no mass is lost when I break my fingers, it's just moved around.' Another storm of ice shot out, so another Smash was used.

"Aww Man it started?!" Karishma whined as he ran into the student box. "Hey Karishma! Congrats on getting to the second round!" A student stated. "Yeah! I'll be up against you Bakugou! Let's have a good fight!"

"Good luck." the explosive teen growled. "HA! You'll need it!" Karishma laughed. "Anyways, you and Todoroki can shoot off large scale attacks constantly! It isn't fair!" Sero leaned forward to join the conversation. "And you can do it with no time lag!" Katsuki scoffed. "I don't just fire them off willy-nilly. Imagine muscles. If you overuse them they tear, and it gets harder to use them. Go over that and you can seriously damage them. The same is true for Quirks. There's always a limit."

"Even for your Quirk?" Karishma asked. "Can you sweat indefinitely?" Bakugou asked. Karishma shook his head. "Exactly."

Back at the stage, Todoroki was beginning to understand. "An endurance match, huh? Well then, I'll finish you quickly." With that he fired off yet another blast. Izuku used another finger. 'I've used up my right hand!' He noticed that his right middle finger was almost healed. 'Just as I thought. I'll heal fast enough to reuse it.' And then Izuku noticed Todoroki using his ice to get close. 'Shit!' he thought, using his left middle finger. The blast destroyed the ice Shoto was using, but the teen just leapt off of it and covered his fist in ice. Izuku rolled out of the way, and unleashed his (now healed) right middle finger, blowing Todoroki away. The teen managed to catch himself. "Are you telling me to stay away?" Shoto asked. Izuku then grew his claws, noticing that all the pain in his fingers went away. "And why do you think that is?" Izuku mockingly asked. And then he noticed something.

'He's trembling? Is he afraid or is it just the cold?' "I must say thank you, Midoriya. His face is clouded over." Izuku's opponent motioned over to Endeavor. He did look angry. "However, even with your regenerative abilities, you can't keep this up. Eventually you'll be unable to keep up. How about we end this?" And with that, he let loose yet another high-powered attack. Izuku just casually lifted a clawed hand and sliced the ice away. "I noticed that you're trembling, Todoroki. You're cold, aren't you? After all, there has to be a limit to how much your body can take. And you could easily use your left to take care of that, right?"

"Like you're one to talk. I know you're not even fighting at half strength." Shoto stated. "You want me to fight with all I have? Really?" Izuku asked. "Very well, but I expect you to do the same," he stated with zero emotion. And with that, the tendrils sprouted. "And the tendrils return! What are they and what can they do!?" Mic shouted. Aizawa turned, and then remembered that Mic hadn't seen what they did.

"Did my old man buy you off!?" Todoroki growled, sprinting towards Izuku, but then Izuku slammed a tendril right next to Todoroki. Shoto stooped, both from knowledge of what those things did and basic instinct. "Quite the opposite actually, but that doesn't matter." Izuku said to the now-standing still teen. He slowly got up and took a step forward, tendril advancing at an equal speed. Todoroki froze it over with ice, but the tendril vibrated so fast that it shattered the ice. "I'll have you know that they're immune to cold." Izuku emotionlessly stated. "I tested it out when I was younger. I stuck them in a freezer. Nothing happened."

"You sound like you don't like them," Todoroki stated, keeping an eye on the tendrils. "And why would you think that?" Midoriya sarcastically stated. "Is it because you know damn well what they're for!?" He was shouting now. That frightened Shoto. Izuku took another step forward. Then another. And another. The tendril moved forward as well, and Todoroki kept backpedalling, trying to freeze them. "Why is everyone so afraid of those?!" Mic shouted. Aizawa rolled his eyes.

"Why are you doing this?!" Todoroki shouted. Izuku smirked. "You wanted me to give it my all, so here I am, doing just that." Up in the stands, Toshinori froze. 'That tone…'

"What? Are you not going to as well? Is that it from you, Shoto Todoroki? Are you just gonna refuse to use your full power? Are you going to handicap yourself just because you think your Quirk is too much like your father's? Well, news flash! It's not his! It's your Quirk!"

"You know nothing!" Shoto shouted. Izuku stopped, his face expressionless. "Wanna know something? In spite of my Quirk, I have an extra toe joint. And somehow, that knowledge was leaked out. I had to deal with the stigma of being Quirkless throughout my life, with only Kacchan, his family, and my family knowing otherwise. I've had to deal with bullies, both from students and teachers. Heck, there was only one teacher who didn't see me as garbage! She stood up for me! That year was the only year where I didn't have to repeat a certain mantra in my head over and over! Wanna know what is was?!" Izuku was smiling savagely. "'Don't hurt them! Don't hurt them!' You, Shoto, know nothing of the hell I've put myself through in an attempt to keep those who despised my existence alive!"

Up in the stands, the rest of 1-A turned to Katsuki. "I-is that true?!" Sato asked. Bakugou nodded. "Every day he got bullied, save for our second grade. And every day, I heard him muttering that mantra. I was there when his Quirk first activated, so I knew what it did from the very beginning. And you know what? At least once a week I'd have a certain nightmare. I'd see Deku slaughter the entire class, saving me for last. I'd wake up the moment before a tendril gutted me as he roared. Every jeer, every punch, every time they picked on him, I felt fear. After all, there's only so much anyone can take. Trust me, if it had been anyone else, he would've snapped long ago."

Back on the field, Todoroki stared at Izuku. "So, are you gonna use your fire?" Izuku snarled, "Or are you gonna lose?" He then picked up Todoroki. "Either way, I have to thank you." That made Shoto freeze. "T-thank me?" Todoroki stammered. Izuku grinned sadistically. All Might paled. 'That face… that tone... '

"Thank you for such WONDERFUL comedy!" he yelled, throwing Todoroki just short of the disqualification line.

At the base, Hisashi laughed. "Oh yes! I wish I could see the look on All Might's face right now!"

When Izuku said THOSE words, in THAT tone, with THAT expression, Toshinori coughed up a literal fountain of blood. "All Might!" 13 whisper-shouted in fear. Toshinori wheezed, struggling to get up after he had propelled himself backwards. He was shaking, both from blood loss and flashbacks. 'No… NO! NOOOOOOO! Izuku Midoriya is not HIM! Izuku Midoriya will never be HIM! Izuku Midoriya cannot POSSIBLY BE ANYTHING CLOSE TO HIM!' Yagi mentally screamed. He noticed 13's hand. "T-thank you 13." he gasped.

Shoto saw Midoriya moving closer and closer. "So are you gonna get it through your head that it's not your dad's Quirk, but your own?" He snarled. In response, Todoroki lit up his left side, unleashing a torrent of fire. "W-what is this?!" Mic shouted. Up in the stands, Yagi realized what Izuku had been trying to do. 'So you made him use his left side… were you trying to save him from himself?!'

Back on the stage, Todoroki sent a burst of fire at the tendril. The tendril shriveled and retreated. "Why did you help your enemy!?" Todoroki shouted. "Because you needed it!" Izuku shouted back. Now that that was out of the way, Izuku primed One For All into his leg and his right arm. Meanwhile, Todoroki slammed his right foot down, no longer at risk of giving himself frostbite. "Midnight!" Cemetoss shouted. "If they go any further…!"

"RIGHT!" She shouted. She ripped her suit a bit to release the gas that put people to sleep. Izuku was the closest, so he'd be the one affected. However, he just shrugged it off. Todoroki let loose another glacier, and Izuku used his leg to dodge it. 'I have to get closer!' He thought. Todoroki primed his fire side, and let loose. But first, he decided to say something. "Midoriya… thank you." The two attacks met, but only after going through several cement columns Cemetoss had hurriedly thrown up. The resulting collision, along with the previously cold air, created a massive explosion. Said explosion blew Midnight, Cemetoss, and Mic back, although Mic's was from shock. "W-what the heck was that?" Mic muttered. Aizawa just sighed. "That was the two most powerful students deciding to give it their all." he flatly stated. "W-what is going on… the smoke is blocking the stadium…" Mic whispered, now beginning to sit up. Midnight blew away some of the smoke, and saw an interesting sight. Izuku's right arm had become a blade, which was impaled into the ground, barely holding him in bounds. Shoto, however, had burned through his uniform on one side, and was slumped against the back wall, the force of the collision having pushed him there. "Sh-Shoto is out of bounds… Izuku Midoriya advances to the third round!" Midnight shouted, cracking her whip.
