It was a quiet day at 1A dorms except for the occasional scream or laughter from the class.

In the common room the entire class was trying not to die from the adorable scene in front of them.

Eri was on Izuku's shoulder's giggling as he used Float and flew around the common room.

"Papa this is so much fun" said Eri with a smile on her face, when Izuku saw her truly smile he ended flooding the first floor of the dorms with tears.

"Hehe I'm glad you like it snowball now hang on" said Izuku before he pushed himself off a wall flying around.

"This is too adorable..." Said Jiro holding her heart "this should be illegal".

"I agree... This is too wholesome" said Momo smiling.

After a couple more minutes Izuku eventually put Eri down "alright snowball I have to go and train ok?" Said Izuku.

"Okay Papa me and mommy will have some fun then" said Eri running off to find Ochako.

Izuku smiled and walked towards the gym area to get in some more training, he didn't get far till he noticed someone walking up to him.

"Deku let's train" said Katsuki walking up to him.

"Hey can I join bro it'll be so manly if we all trained together" said Kirishima popping out of nowhere.

"Hm sure why not I think it'll be great to train together" said Izuku before Katsuki walked up to him with a intense glare.

"... Deku... WHEN THE FUUUUUUUUUUUUUUDGE DID YOU GET TALLER THAN ME!!!!" Screamed Katsuki with a vein on his forehead while catching himself.

Izuku blinked a couple times before he realized that he was about a inch or two taller than Katsuki now.

"Oh hehehe I guess I didn't notice with all that's been going on in my life lately" said Izuku scratching the back of his head."don't worry Katsuki I'm sure the weather is lovely down there". He then walked away leaving an enraged Katsuki.

"THE HECK YOU SAY!!! I'LL BE TALLER THAN ALL OF YOU BASTARDS!!! NO SCREW THAT I'LL BE TWICE AS TALL AS ALL MIGHT!!! THEN YOU CAN KISS MY 14 FOOT BUTT!!!". Screamed Katsuki stomping after Izuku. And angry that he has to catch himself swearing every time now.

"Hey bro it's okay to be shorter than someone" said Kirishima trying to calm him down.

"Bakugo stop trying to overcomplicate like those people who drive trucks with massive lifts. We get it your small so you have to act angry and compensate for it" said Todoroki.

"THE HECK YOU SAY HALF AND HALF!!!!" Screamed Katsuki even angrier.

"That actually explains a lot then, I guess that Camie girl Todoroki mentioned will have to get herself a toy then" said Tsu.

"YOU WANNA DIE FROG LEGS!!!" Screamed Katsuki with a massive blush and more veins popping up on his face in rage.

"Man Bakugo it must really suck being that small and now your also shorter than Izuku" said Shinso snickering.

"THAT'S IT I'M KILLING YOU ALL!!!" screamed Katsuki before Kirishima and Izuku dragged him away. "LET ME GO SO I CAN KILL THEM ALL!!!"

"Don't worry Bakugo I'll ask that Camie girl how big she likes it and make her a toy" said Momo giggling.

Katsuki continued to scream and rage as he dragged out while popping explosions.

"Man who knew messing with him could be that much fun" said Denki still laughing.

"I know right, maybe that's why Nezu asked us to purposefully push his buttons" said Shinso.

In the gym both Izuku and Kirishima put Katsuki down with him still reveling in rage.

"Alright Kacchan let's have a spar it'll help calm you down" said Izuku popping his neck.

"Yea Baku-bro let's do this" said Kirishima activating his quirk.

Katsuki gained a feral smile and kinda scared them both "I'm going to enjoy this way to much".

He then turned to them and released a massive explosion.

Back in the 1A common rooms Eri was sitting on Ochako's lap watching TV while she put her hair in a braid.

"Mommy what will we have for dinner tonight" asked Eri looking up at Ochako.

"Hmm I believe your Papa said he's gonna make us Katsudon" said Ochako.

"What's Katsudon?" Asked Eri.

"Hehe it's your Papa's very meal I'm sure you'll love it" said Ochako finishing Eri's braid.

"If Papa likes it I'm sure I will to, how do I look Mommy" said Eri.

"I'm sure you will and you look absolutely adorable Eri" said Ochako kissing her forehead which made Eri smile.

They were then interrupted by the entire building shacking from a explosion.

"Welp that's definitely your uncle" said Ochako before she heard his screaming in the distance.

"Hehe Uncle Kacchan is very funny" said Eri giggling. "Do you think Papa will like this".

"He indeed is and your Papa will always love anything you wear" said Ochako before she took her hand. "Come on Eri let's go and play outside it's nice and warm".

"Okay mommy" said Eri before she quickly grabbed ghost and held it as she followed Ochako outside. "Mommy when can I see Mama?"

"Well Mama is a pro hero and because All Might isn't a hero, she's much busier than usual. But I'll be sure to call Rumi to talk to you" said Ochako.

"Yay I hope Mama will like my new dress and how my hair is" said Eri hoping she'd like them.

"I'm sure Rumi will love them Eri" said Ochako stopping in front of a tree "well let's get started playing ok Eri?".

"Ok mommy" said Eri as both of them started playing tag with Ochako running after a laughing Eri.

"I'm gonna get you Eri then I'm gonna gobble you up" said Ochako catching Eri and tickling her.

"Ah Mommy stop" said Eri laughing as she kept getting tickled.

"Why what's this a little girl at the prestigious 1A" said a very annoying voice.

Ochako and Eri looked over and saw Monoma with the superior aura around him.

"So the great 1A has lowered themselves even more and brought in a little white haired brat. Oh sorry or should I say test subject" said Monoma laughing.

Eri looked down in sadness as bad memories started to come back that she hoped were forever gone.

"Hey what's your problem why don't you get out of here and stop bullying a little girl. She's been through enough you piece of garbage" said Ochako standing and grabbing Eri's hand intent on leaving.

"Oh so you must be the 1A slut that shares her boyfriend with another woman how disappointing. Not only that but he's a cold blooded murderer, I mean he wants to be a hero yet he goes and kills a villain. He's nothing more than a monster" said Monoma.

"YOU LEAVE PAPA ALONE HE SAVED ME AND HE'S A REAL HERO!" Yelled Eri glaring at him while taking a step towards him.

"Pfft he's nothing more than I murderer that killed a villain so get away from me you disease" said Monoma shoving Eri to the ground.

Ochako glared at him but before she could do anything she heard Eri scream "PAPA!!!!".

Not even a second later a green blur passed them and Izuku was Infront of Eri.

"Eri what's wrong?" Said Izuku looking at her with worry in his eyes.

"Sniff.. he was mean to me and mommy... and he shoved me to the ground..." Said Eri with tears in her eyes.

"Ha so what it's not like y-" said Monoma but was cut off when Izuku fist slammed Into his stomach and sent him flying.

"Ochako take Eri inside and make sure she's ok, I need to have a little "CHAT" with Monoma" said Izuku with rage in his voice.

Ochako nodded and picked up Eri and carried her back to the dorms leaving a very pissed off Izuku who was in angry dad mode.

"HAHAHA YOU TOUCHED ME SO NOW I HAVE YOUR QUIRK!!!" Yelled Monoma who tried to use Izuku's quirk. He tried to punch him but felt nothing and Izuku grabbed his fist.

"Your own mother isn't going to recognize you when I'm done with you" said Izuku as he crushed Monoma's hand which now looked like a crushed can.

"M-mercy..." Said Monoma backing away in fear.

"You made my daughter cry and you hurt her... I'm all out of mercy" said Izuku with a very dark Aura around him and his eyes flashing red.

Xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

"Why do I have the sudden urge to hug Izuku and tell him I'm very proud of him" said All for one.

Xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

"Um... Should we help him..?" Asked Present Mic watching Izuku brutally beat Monoma on the security camera.

"If you wanna go out there and end up in a soup can be my guest" said Aizawa sipping his coffee. "Besides... I'd rather keep my limbs where they are...".

"Principal Nezu can't you stop him?" Asked Vlad King.

"Ha not even I'm willing to fuck with that, there are only two things in this world I won't mess with. One being Midoriya in angry dad mode and the other is Eri's cuteness.... It's way to powerful... Even for me..." Said Nezu.

"Sorry Monoma but... You brought this on yourself..." Thought Vlad King.

Xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

"There I think you learned your lesson" said Izuku looking at the human pretzel that was Monoma and what was left of his face.

He then turned and left leaving him to  wallow in pain and regret.

Izuku walked to the 1A dorms and entered it and was quickly tackled hug by Eri.

"Are you ok Eri" said Izuku kneeling down and hugging her back.

"Papa your not a bad man... Like that mean guy said..." Said Eri hugging Izuku even tighter.

"Thank you Eri" said Izuku smiling and placing a gentle kiss on her head.

"So what did that bassss-loser do" said Katsuki quickly catching himself.

"He was being very mean and rude to us and was reminding Eri of her time.... there..." Said Ochako. "He then called Izuku a cold blooded murderer and shoved Eri to the ground when she defended him.

Everyone looked appalled that Monoma would say that Eri of all people.

"Sniff... He was also mean to mommy..." Said Eri sniffling.

"What the fuck is wrong with that guy?" Said Denki before he realized what he said and went pale.

"Papa... What does fuck mean?" Asked Eri looking up at Izuku.

"EVERY MAN AND WOMAN FOR THEMSELVES!!!" Screamed Katsuki running away with the class following.

"Eri sweety go with mommy up to my room and play with your toys" said Izuku with a sickly sweet smile. "Also that's a bad word don't say until your our age at least".

"Ok Papa" said Eri following Ochako  who picked her up and ran off like a bat out of hell.

"Now Kaminari... I think we need a chat like I had with Monoma" said Izuku grabbing the fleeing form of Denki with Blackwhip.

(30 minutes later)

The class all came back down and things went back to normal until the doors opened and Izuku and Denki walked in.

Izuku had his usual happy attitude around him while Denki was as pale as a ghost and was shaking.

Izuku walked off to Eri and Ochako while Jiro walked up to Denki.

"Kaminari you ok..?" Said Jiro with concern.

Denki flinched and said "f-f-first rule o-of I-I-Izukus r-rules... D-dont swear i-infront o-of Eri...".

Everyone looked at him with extreme concern and had one thought "WHAT DID IZUKU/MIDORIYA DO TO HIM!?!?".
