There was a heavy silence as Shouta sat on the couch, his two boys sitting on the coffee table facing him. The bomb had been dropped and Shouta Aizawa was left speechless. He stood there and waited for the 'Ahhh! Gotcha dad! This was all a big prank!' in a jovial tone.

It never came. As the time ticked on neither Izuku nor Hitoshi could look at him. In fact both boys went to great lengths to look away from him.

Shouta opened his mouth…and then shut in….and then opened it again. He just couldn't think of anything to say. 'I asked about the handprint and…my son has a secret insanely dangerous quirk…' Was all he could think of at the moment. His mind was blank. It wasn't for lack of emotion either. Shouta had plenty of emotions right now. His emotions ranged from anger and disappointment to confusion and a teeny tiny bit of pride. The pride was minuscule though overshadowed by the anger. Hitoshi kept this hidden from him this entire time. Which would be impressive if not for the fact that it was also making Shouta angry for the exact same reason.

And that anger melted away into fury when Hitoshi explained how he managed to keep this quirk hidden for so long.

"...So, you're telling me… that you- Izuku- have a sentient quirk. It not just any quirk either. This quirk can take other quirks and, according to Hitoshi, feeds off chaos and is basically bloodhungry?"

"Yes?" Izuku whispered while shrugging his shoulders. He didn't know himself exactly. "It's hard to explain."

"...I want to see." Shouta suddenly said making both boys look at him in surprise.

"What?" Izuku's breath hitched. "Dad… this quirk is dangerous-"

"Zuchan is right. This is why I kept it a secret." Hitoshi jumped up.

"Exactly why I need to see what I'm going to be dealing with here!" Shouta snapped growing increasingly impatient with his two sons. He then turned towards Hitoshi and snarled at him. "You are aware that because of what you've been doing is why this quirk is going haywire, correct?"

Hitoshi looked startled at his father. "W-"

"Hitoshi, Izuku has no training on how to control this quirk. He's been too focused on training One for All because he had no idea that he actually had a quirk. Everyone needs quirk training and you hindered that by stepping in. The first time I completely understand, you were a scared five year old who messed up, but the other times? You knew exactly what you were doing and you never once thought about coming to me about it."

"I…" Hitoshi's breath hitched a little; he then steeled himself and tried again. "I was protecting all of us with my actions. Was it the best option? No, I'll be the first to admit that."

"You should have told me!" Shouta immediately turned angry. "God dammit, Hitoshi! We could have gotten Izuku the training he needed in this matter!"

"Please don't yell-" Izuku tried to say but it fell on deaf ears.

"Training won't help in this situation!" Hitoshi yelled back to Shouta. "Izuku's quirk is a monster!"

"Hitoshi, I can erase quirks! You should have told me! It doesn't matter how loud and destructive this quirk is! I can at least stop it and help tame it!"

"Please-" Izuku whimpered as he covered his ears.

"You think you can tame that thing!?" Hitoshi snapped back. "His own biological father couldn't even tame it!"

"That's not for you to decide! I understand you want to protect Izuku! But you've way overstepped your boundaries with what you've been doing! God dammit, Hitoshi! I just…I don't understand!"

"Understand what?!"

"Why you don't trust me!"

"SHUT-UP!"

It wasn't Hitoshi that yelled that. No, it was Izuku. Izuku's hair was turning white right in front of Shouta's eyes. Izuku was trembling from his spot on the coffee table. He had his hands buried into his curls, that was starting to straighten out by the second. Izuku was grinding his teeth sharply as he inhaled rapidly.

Shouta felt his breath sweep out of his lungs as the cats fled the room.

There was a dark aura surrounding Izuku as he almost seemed to struggle with himself. He was grinding his teeth so harshly that Shouta was afraid that Izuku was going to break them. Izuku made a sound like he was in pain as he stood up. He doubled over on himself, his hands still entangled in his hair as it looked like he was fighting for control. 'Because he is.'

"Zuchan-" Hitoshi took a step forward-

"Don't touch me!" Izuku yelled at Hitoshi. His tone was sharp and clipped, a tone Shouta never heard before. Then Izuku looked up. His eyes were red. No longer the bright loving green Shouta has grown accustomed to. The iris's were a scarlet red.

Shouta was ashamed to admit it: his legs trembled ever so slightly and he swallowed hard.

"I've been waiting for this moment, Toshichan-" Izuku- No, Izuku's quirk. Shouta needed a new name for this quirk. 'It reminds me of that American movie. With the dog that got rabies…' Aizawa could only think as he watched this crazy quirk for just a moment. He was feral whereas Izuku wasn't. He was everything Iida, Hitoshi, and Todoroki told Shouta about.

"The other me was holding me back from getting to you. You don't deserve that quirk of yours-"

Red tendrils shot from the Quirk's fingers- And they died down just as swiftly.

Shouta grabbed the ends of his scarf and wrapped the quirk up tightly. "Calm down there, Cujo." Shouta hissed as he made sure his scarf was tight and snug. "You're not hurting Hitoshi."

"Cujo!?" Hitoshi gasped as he fell back into the couch. "You did not just name this thing!"

"I am not a thing!" The quirk, now named 'Cujo', snarled in his endless anger. Cujo struggled against Shouta's capture scarf growling and groaning like a rabid animal.

'Cujo is definitely a fitting name for this thing.' Shouta thought as he watched. Cujo kept trying to summon his tendrils. 'No doubt how he takes these quirks.' Shouta kept his eyes and quirk on Cujo.

"What did you do!? Why aren't my tendrils coming out!" Cujo started to whine after only a few seconds. He wiggled his shoulders, his struggle dying out by the second. "Stop it!" He cried and and tried to pull against Shouta's scarf, but Shouta held strong.

"So…this is what you were so afraid of, Hitoshi?" Shouta teased with a bit of a flat smile on his face. "Yes, the sentient quirk I can't get rid of but those tendrils are fair game. It's not a mutation. Why, this is no different than Bakugo at this point." Shouta mused a little as Cujo never gave up his struggle.

"Release me!"

"No, you need to calm down first." Shouta hissed to the quirk. Then, inch by inch, Shouta started to pull Cujo towards him.

Cujo snarled at him, his lip raised like he was going to start biting. It was an unnatural seeing such a face on Izuku. They were soon close to one another. Shouta kept a bit of a distance, but he just wanted this thing to look at him. "So, I have some questions."

"I bet you do, old man!" Cujo snapped immediately. "What, did alzheimer's kick in already?

Shouta narrowed his eyes at the insult. "The fire quirk. Where'd it come from?"

"Wouldn't you like to know- gak!" Shouta tightened his scarf around Izuku's torso. Cujo gagged as all air was pushed out of his lungs with one quick movement.

"Let me make one thing clear." Shouta snarled right back at the quirk. "This is something that I have instilled in both Hitoshi and Izuku alike, but you're not Izuku, are you? No. You're Cujo. So, Cujo. I don't take disrespect well."

"Do-gak- your worse! You old geezer! I'll take any hits you have to offer!" Cujo snarled bitterly as he tried to thrash again.

"I don't hit." Shouta stated in a sharp tone.

That got Cujo's attention. His thrashing stopped as he looked at Shouta. Sweat starting to pour from the crown of his head as he glared angrily. He panted in and out for breath as he just stared. "Doesn't matter…" Cujo huffed before smiling. "I know your quirk by now. You need to blink sometime, right? Those eyes are looking mighty red…" Cujo continued to pant as he struggled against the bounds once more. The smile started to grow. "Then I'll take your quirk. Yours and Toshichan's."

"Is that so?"

"You can't stop me!"

So, Shouta tightened the scarf even more. There was another gasp from Cujo as even more of his oxygen was taken from his lungs. Shouta was sure Cujo couldn't even expand his chest at this point. Then, Shouta blinked. It was sweet relief he needed and look at that, Cujo didn't attack. He couldn't. He was doubled over on himself as he started to wheeze. His face started to turn a nasty shade of red as more sweat poured from his face.

Shouta grabbed his eyedrops to lubricate his eyes. Once he added a couple of drop into each eye he looked at Cujo. "I don't hit. In fact, I never raise my hands. I instead use my scarf. Both of my boys know better than to act the way you have."

Cujo let out a strangled cry as sharp gasps left his mouth.

Shouta looked at him and tilted his head. "It would be best if you wisened up-" He warned as he released Cujo from his scarf. Cujo hit the ground on his hands and knees. He then sucked in several greedy breaths. His whole form trembled. Shouta then walked over to Hitoshi.

Hitoshi felt at a loss for words as he looked at Cujo on the ground.

"I'll kill you…" Cujo threatened with a growl from his spot on the ground. He looked up at Shouta with a such a steaming hatred that it made Hitoshi squirm. Cujo's red eyes were aflame with fury. "You won't get away with what you've done- Urg! Not now!" Cujo grabbed on to his head as he gave it a violent shake. "You're not taking over! I'm not done yet!" He yelled to seemingly no one.

Cujo sucked in a breath before screaming out like he was being tortured.

"Izuku." Shouta spoke in a commanding tone a tone that made Cujo look up at him. "Control your quirk. I know you can. You have to regain control. Not only that but you have to learn how to quickly regain control over this quirk whenever it gets violent."

Cujo looked at Shouta with wide and wet eyes. Then his eye color began to flicker. It was almost breathtaking watching as his eyes went from red to green in such a fast manner. Cujo grabbed on to his hair with both hands. "This- this isn't over!" Cujo declared in his anger. "Try as you might, one day I'll get the upper hand on you! You'll never see it coming!"

"Goodbye, Cujo."

"Jokes on you, Old man…" Cujo gave a wobbly smile. His hair started to curl back up and regain it's familiar black and green coloring. "I actually like that name. I've never had one before." Then his eyes flickered to green and stayed green before rolling up into Izuku's skull.

Izuku promptly fell face down on the carpet going completely limp.

"Zuchan!" Hitoshi jumped from the couch. Shouta raised a hand and brought it out. This halted Hitoshi instantly. Once Hitoshi stopped Shouta approached.

He got down on one knee and lightly poked Izuku's cheek with his finger. "Izuku, get up."

Izuku's eyes twitched before he suddenly opened them. "Dad?"

"Yeah, I'm here. How are you feeling?"

Izuku gave a groan as he slowly pushed himself off of the carpet. "Like a truck hit me. Why does my chest hurt?" He wheezed softly as he pressed a hand against his chest.

"Sorry about that, Cujo got a little crazy. I had to put him in his place." Shouta was softer as he helped Izuku to his feet.

"...You named my quirk after a rabid dog?" Izuku whispered through his panting as he gave his father an incredulous look.

"It felt fitting." Shouta shrugged.

"It's fucking perfect and that's why I hate it." Izuku cursed as he sucked in a few swift breaths. Hitoshi came up and looked from Izuku to Shouta.

Shouta raised an eyebrow at Hitoshi once they looked eyes. "Still think I can't tame that quirk, Hitoshi?"

"...You impressed me. I'll give you that." Hitoshi admitted. "From what little I've seen in the lab…his father would often try and beat the quirk down if it got too out of line. Though that happened very little. He often gave the quirk- Cujo- free rein. I think to study it-"

"Yeah, that reminds me…" Izuku turned to Hitoshi swiftly with fiery eyes. "You knew my father was the one who kidnapped us!"

"I did."

"How dare you keep that a secret for me! The quirk I understand but- You had no right to keep my biological father a secret!" Izuku was infront of Hitoshi in record time.

"Trust me, Izuku. I understand how you feel and punishment will be discussed." Shouta pulled Izuku back. "But don't go getting riled up. Besides, something is telling me Hitoshi already feels bad about all of this." Shouta looked at his other son.

Hitoshi did look away as he rubbed at the back of his head. "Look…I'm not going to say I made all the right choices, I know for a fact there were far better things I could have done, okay, but I had my reasons for doing what I did. Everything I did, though not the best, was to protect you. Both of you. I-" Then he covered his face with his hands and gave his head a shake while he laughed. "I'm just glad it's all off my shoulders. You don't know how exhausting it's been!" He cried dramatically as he fell to his knees.

'Eight, almost nine, years he kept this a complete and utter secret. He never once wavered and always stood strong.'

"Look…" Izuku spoke next. "I-... " Izuku spoke softly only to stop. "…I don't think I can forgive you for this." He whispered while crossing his arms over his chest. He then looked away from Hitoshi.

The words hurt. It was like Izuku just slapped him across the face. Hitoshi knew he deserved it but it didn't sting any less. "I'm sorry." Hitoshi whispered weakly as he looked away from Izuku. "I know I can't ask for your forgiveness. That wouldn't be fair…from either of you. I know I lied again and again…but I swear…I'll make it up to both of you the best I can!" He stated proudly as he stood from his spot on the floor.

"That's all we can ask for, I suppose." Shouta agreed with Hitoshi. "Also you are now grounded until I deemed fit."

"Dammit."

"Oh, that's just the start of the long list of punishments I'm planning for you. So, don't get too disappointed just yet."

Hitoshi whined while a puff of air left his mouth. "Fair…" He felt himself tear up. Not because of of the punishments, but maybe it was just because he was finally able to let it all out. That he wasn't bottling up secrets anymore. Still, now that everything was out in the open…

Hitoshi felt rejection creep up his spine. He felt like that the relationships he worked so hard for these past years were just shot because of his own stupidity. That this was it. Would his father give up his rights? Was one of those punishments giving Hitoshi away to the nearest orphanage?

Tears sprung in Hitoshi's eyes. He tried to wipe them away, but he wasn't fast enough. He was caught fairly quickly. "Why are you crying?" Izuku inquired in a soft voice.

"It's stupid." Hitoshi softly tried to wave Izuku and his father off while he wiped his tears away with his palm.

"If you're crying it's not stupid." Shouta explained gently as he approached. "What's wrong?"

"It's just… you're not… you're not going to get rid of me over this, are you?" Hitoshi whined while he shook his head. Hitoshi then wiped away his tears as quickly as he could.

"Where on earth did you get that idea-...Hitoshi." Shouta grabbed Hitoshi by his shoulder, forcing Hitoshi to look at him. "I'm disappointed in you, but I will never just throw you out like your nothing. You're still my son. I will always love you. Get that through your head."

Hitoshi blinked at those words as he sniffled again.

"Yeah, you're still my brother! I may never forgive you for what you did, but I still love you! You're my second half and-...I can't imagine my life without you!" Izuku chimed in just as quickly. Then, before Hitoshi knew it he was being hugged. Not just by Izuku, but by his dad as well.

Hitoshi sniffled softly and he swiped at the tears that continued to fall, but these were arguably happier tears. Knowing that he was still loved made all the difference in the world.

"Okay, this just leaves one question that hasn't been answered yet." Shouta whispered as he pulled away from Hitoshi first. Both Hitoshi and Izuku looked at him. He looked at them before scratching the back of his head. "Izuku, can I see you use the fire quirk?" He asked.

Izuku nodded a little uneasily. "It's the first time I'm using it… so…forgive me." He took a step away from his father.

It came easier than Izuku had expected. Perhaps because he knew he had such a quirk. He felt heat against his palm, he then shut his fingers around his palm before opening them up. A small orange flame danced around his palm with this movement. The flame was bright orange and mesmerizing to look at it as it danced from side to side.

Shouta watched, equally amazed. Izuku shook his hand extinguishing the flame instantly when it felt like it was getting just a little too warm. "I just needed to confirm it for myself." Shouta explained. He then tapped his finger to his chin. "So, that brings me to my question. Who did you steal it from?"

"Cujo stole it. I didn't."

"My point stands."

"I don't know…"

Hitoshi turned away as he looked up at the ceiling. Shouta narrowed his eyes. "Hitoshi… do you know something?"

"Hm? Me?" Hitoshi pointed at himself. "I…uh…" He sighed. "Endeavor. Cujo stole it from Endeavor."

Both Izuku and Shouta turned towards him with wide disbelieving eyes. "Wh-What?" Izuku whispered almost fearfully. "You're saying…I made Endeavor quirkless?"

"Yes. The moment Todoroki mentioned it; I knew instantly." Hitoshi shoved his hands in his pockets. "And I wish I could tell you how to return quirks, but that's something even I don't know."

"So, Endeavor's quirk is the only quirk that's not yours?" Shouta asked Izuku. This time it was Izuku that looked at the ceiling.

"Right… No. The object attraction isn't mine."

"What?"

"It's…dad…I subconsciously stole it from Inko." Izuku whispered. "It's like at the USJ. Where I subconsciously stole Hichan's quirk. I don't think Cujo needs to come out if I already took the quirk once or twice. In fact. I took her quirk before I got One for All if all that Hichan told me is completely correct."

"It is." Hitoshi grumbled as he looked away from the two of them.

"Okay… so right now you have two quirks that aren't yours that we need to return to the right owners… I guess the next thing we need to work on is training Cujo and trying to get him on our side." Shouta explained to Izuku. "It'll be tricky, but I know with the three of us we can help train and even tame him. Right, Hitoshi?"

"..." Hitoshi looked at his father. "Hey, you disproved me tonight, old man. No need to rub my nose in it."

Shouta raised an eyebrow at Hitoshi. "Excuse me?"

"What I'm trying to say is: If anyone can tame Cujo. It's you. After all, not even All for One could tame Cujo. and it's basically his own damn quirk."

"..." Izuku looked at him slack jawed and wide eyes. "What…what did you just say?" Izuku whispered.

"Right…I guess there's no point in hiding it anymore. Izuku…the reason I freaked out the day you got One for All isn't because I thought you stole a quirk. Izuku… your father, his name was All for One. and by extension…so is Cujo. He is also All for One. but not because he was biologically passed down to you."

"..."

"So… Izuku's father is named All for One, as is Cujo by default because they got the same quirk, and Izuku got One for All from All Might?" Shouta asked his own jaw falling open as he looked at Hitoshi.

Hitoshi nodded. "Yeah, do you see why I freaked out that day? It's not a coincidence. It just can't be."

"All for One-..." Izuku grabbed on to his head.

"Izuku! Is Cujo coming out?" Shouta demanded as he turned towards Izuku. Izuku gave his head a shake while he whined.

An image flashed through Izuku's mind like a firework. A man, tall, taller than anyone Izuku has ever seen. This man holding Izuku on his hip with ease while smiling at his son. White hair, red eyes, rough hands that would gently boop Izuku's little nose. A man who would hum whenever Izuku would come to him with a fever. A gentle man-

A man who punched Hitoshi across the face. Who would yell and curse, while kicking Hitoshi to the ground, who would only stop when Izuku would beg him to.

"No…No." Izuku shook his head firmly. "It's not Cujo…" he whispered weakly. With shaky hands Izuku reached out and grabbed on to his father's wrist. "I just… I just remembered something." His father's hero costume was itchy, and the ends of the wrist were worn and tattered. It was keeping Izuku grounded, stopping him from flying into a panic attack.

He could hear it, screams in the back of his mind. Hitoshi's cries for his mommy and daddy while he tried to scramble away from an enraged All for One. Hitoshi tried to hide under his bed and All for One ripped it up tossing it into the hallway. Sending Hitoshi into an absolute fearful screaming fit.

'What attempt was that? Four? Five?...' Izuku hands cotninued to tremble and shake violently. His father, clearly seeing this, grabbed on to Izuku's own wrists. "Breathe." He ordered softly.

All for One scooped up a crying Izuku. "Now, that should teach you a lesson, Young one. No more running off like that. Otherwise Hitoshi will get hurt again. Understand… come now, stop that crying. After all, it's not you I hurt now, is it?"

Shouta pulled a crying and dulled-eyed Izuku into a hug. "Shhh…" He whispered while gently rocking side to side. "I think something triggered him." Shouta whispered the last part to a worried Hitoshi. "I want you tell me everything you know about All for One, Hitoshi. Then, when it's said and done I'll call Toshinori. He has to know something."

"I'll do what I can, but I don't know everything."

"I'll take what I can get it. If his father is as bad as you stated previously. That he makes normal hero 'piss themselves' as you put it. Then I need all I can get my hands on. Especially if he and Izuku have the same quirk."

"...Well, I can start with this. Cujo is stronger. Cujo can take quirks that All for One can't…"

So, while writing this chapter I was thinking of this old full house episode. I can't remember what it was about but Stephine (I think) had done something bad and tried to hide it (I think.) and she was yelling at her dad how she was scared he'd "Never want to hug or kiss me again because of this." and Like…I could only think of Hitoshi having that exact same thought in a weird sense.
