Aquaman POV.

I can't believe this right now they experimented on the boy with my DNA, how the fuck did they even get so much of my DNA to do that. Maybe they got it from Black Manta, my last fight against him was pretty bloodie and he managed to get away in the end maybe he collected some of my blood anyways right now we have a different problem.

Batman :,,The boy will have to go with you Arthur."

Aquaman :,,Why with me?"

Batman :,,A part of the boy is Atlantian now some of his powers also came from some sea creatures, if my theory is correct then you are the only one able to calm him down in case he gets out of control."

Martian Manhunter :,,Yes if it is true what the files we found say about him then he may be the strongest being on this planet."

Superman :,,Stronger then me?"

Batman :,,Maybe."

Batman talked to Martian Manhunter while I walked into the room of the boy, I opened the door and saw the boy laying on the bed peacefully sleeping it was quiet besides the beeping of the monitor besides him. I looked at the face at the boy and he looked so peaceful, it must have been a while since the last time he could sleep without pain. I looked at the machines that were there and saw two IV-Bags that were connected with the boy, both were probably filled up with painkillers, I touched his ears.

Aquaman :,,They are really like fins."

Just then I heard someone screaming outside, I turned my head to the door before walking to it I glanced back to the boy before I opened the door and saw what was going on. I saw  4 people one of them was older blonde man, two green haired women and one green haired boy they were curently screaming at Batman and Superman demanding to be let through.

Superman :,,Not gonna happen."

I walked out of the room and closed the door behind me without looking back, so I didn't saw that the boy has woken up because of the screaming.

Izuku POV.

I woke up as I heard someone screaming, I opened my eyes and saw a white ceiling. 

Izuku :,,Where am I?"

I could hear beeping besides me and saw a monitor with numbers and lines on it. Then I looked a little to the left and saw IV-Bags and they were connected to my arm I shot up and ripped them out as fast as I could together with the other tubes and strings the screen besides me let hear one long beep that just continued. I looked around and saw a white room with a big window, I got out of the bed what was pretty comfortable compared to my other one I then walked towards the window as I could hear the screaming again. I turned around and looked towards the door listening closely. The voices sounded familiar but from where I tried to remember but then I heard a voice that I would recognise anywhere.

Katsuki :,,LET US FUCKING THROUGH!!!"

Izuku :,,N....no...... why is he here?"

My head began to spiral as I started to remember the beatings I received from Katsuki, the Todoroki's and my siblings. It was getting hard to breath my vision became blurry and I sank to my knees as I remembered the beatings the insults and everything, I then heard the voices coming nearer to the door I tried to stand up but as I tried I fell straight on my face. I tried to get up again only to find myself unable to do so, my legs also felt weird I looked down and what I saw shocked me instat of my legs there was long fish like tail.

Izuku :,,AAAAAAAAAAAAAAAAAAAAAAAAAAHHHHHHHHHH!!!!"

No one POV.

We can see Superman and Batman standing infront of the Yagi's blocking their way into Izuku's room, Wonder Woman, Martian Manhunter and Aquaman just stood back watching the show together with the other people that came with the Yagis until a boy with spicky blonde hair spoke up.

Katsuki :,,LET US FUCKING THROUGH!!!"

Superman :,,Watch youre mouth boy."

Inko :,,Please let us trough I need to see my baby!"

Batman :,,You're baby, acording to the file........"

Izuku :,,AAAAAAAAAAAAAAAAAAAAAAAAAAHHHHHHHHHHHHHHHHHHHHHH!!!!!!!!!!!"

Itami and Izumi :,,IZUKU!"

Itami and Izumi tried to get past Superman but he stoped them while Aquaman and Wonder Woman ran to the door. Aquaman opened the door and immeadiately dodged a chair that came flying out of the room, he looked into the room and saw Izuku on the ground panicking but the thing that shocked him the most was that instat of legs he now had a around 4 meter long merman tail. 

Aquaman :,,John we need you!"

Aquaman ran into the room  followed by Wonder Woman and Martian Manhunter. Aquaman dodged the tail as he ran towards the boy while Wonder Woman grabbed the tail and pinned it to the ground so that he wouldn't cause any more damage. Martian Manhunter came through the wall a floated towards Izuku, while Aquaman held the boy by his shoulder  trying to calm him down, Martian Manhunter got on his knees beside Aquaman and pressed his hand against the forehead of the boy. Izuku continues to struggle and scream but they soon faded as Martian Manhunter put the boy to sleep with his powers, Wonder Woman then let go of Izuku's tail as Aquaman lifted the boy up bridal stile. Martian Manhunter used his powers to lift up the hospital bed that Izuku threw over in his panic, Aquaman then continued to lay the boy down on his bed. Then the Yagi's finally managed to get past Superman and Batman and stormed into the room followed by their other family members and what they saw shocked them to their core as they saw Izuku laying on the hospital bed with a 4 meter long green colored merman tail. Batman pushed past the shocked family and walked towards Aquaman.

Batman :,,Do you see now why he has to go with you?"

Aquaman just nodded.

Itami :,,What do you mean, my little brother isn't going anywhere!?!"

Izumi :,,He is going home with us!!"

Superman :,,No he won't."

This time Nezu stepped forward and faced Superman.

Nezu :,,They are his family they have every right to take him home with them."

Batman :,,They were his family."

Batman stepped between Nezu and Superman a file in his hand that was when Endeavor spoke up.

Endeavor :,,What do you mean they were?"

Batman :,,This is his file that we found during the raid on the lab it not only contains all information about his powers and forms but also some interesting information about the Yagi family"

Nezu :,,Could I please see the file?"

Batman gave the file to Nezu and Nezu opened and started to read it while Endeavor also leaned down to read with him.

Batman :,,Those information are also the reason why a old foe of you All Might helped Luthor."

Toshinori :,,What do you mean what old foe?"

Batman :,,Tell me do you know someone who can take and give quirks?"

Toshinori :,,You don't mean....."

Batman :,,Yeah I mean him in the file is stated that he successfully gave a combination of quirks to the boy creating a new one." 

Rei :,,You mean the quirk caused this?"

Rei pointed at the tail of the boy.

Superman :,,No...... the quirk the boy got is a weather quirk that what you are seeing here was caused.... through constat experimentation with quirk genes, atlantian dna and highly dangerous chemicals."

Flash :,,In the lab and in the file he is labeled as project Jörmungandr."

Aizawa :,,The world Serpent from norse mythology?"

Flash :,,Yes."

Just as Flash was about to continue Toshinori was send flying and crashed into a wall, everyone minus the heroes of the league were shocked to see that Endeavor punched Toshinori.

Inko :,,What the hell Enji!!!"

Endeavor :,,You........"

Endeavor walked up to the smaller woman and grabbed her by the neck before lifting her up on eye level.

Endeavor :,,You..... HOW COULD YOU HE IS YOURE SON YOURE OWN FLESH AND BLOOD!!!"

Rei :,,Enji let her down, what has gotten into you!?!"

Rei tried to approach her husband but she was stoped by Nezu, she looked down to Nezu and saw him holding up the file for her to read.

Nezu :,,Read this then you will understand."

Rei took the file and Mitsuki, Masaru, Natsuo, Fuyumi, Aizawa, Naomasa and Gran Torino joined her standing around her reading the file with her.

5 minutes later:

Rei :,,Get out of here now!!"

Natsuo :,,Mom please don't scream we are in a hospital."

Fuyumi :,,Shoto, Shoka how could you do this we thought he was youre friend?"

Mitsuki :,,You fucking brat if it weren't for you then Izuku wouldn't be in this state!!!"

Masaru :,,............"

Aizawa :,,From all people in youre class you were the most heroic one Itami."

Itami's head hang low as tears threatend to come out.

Gran Torino :,,Get out now."

Toshinori :,,Sensei, I....."

Gran Torino :,,OUT NOW!!"

Doctor :,,Sir, I called the security as ordered."

Batman :,,Thank you."

8 Security guards came through the door, two took Toshinori and the others took Inko and the kids and began dragging them out of the room. Izumi and Inko screamed alot as they were dragged out, Shoto and Shoka just silently walked out of the room followed by Katsuki with a 'tch', Toshinori and Itami looked angry but didn't wanted to cause any destruction so they walked out of the door with their fistes clinched.

Rei :,,I can't believe this...."

Fuyumi :,,Mom...."

Rei sat down in the chair besides Izuku's bed who by everyone's suprise didn't woke up by the noises.

Naomasa :,,He lied to me all those years and I believed him..... hehe kind of funny considering my quirk is lie detector."

Just then a slap noise could be heard through the room, everyone turned to look at Izuku and saw that his tail was moving a bit and as they looked at his face they saw that his eyes were slowly opening. Rei leaned over and grabbed the boys hand, Izuku slowly turned his head towards Rei with his eyes half closed as he saw her a weak smile came to his face.

Izuku :,,Auntie......"

Rei :,,Izuku..."

Rei lifted the boy up a bit and hugged him, Izuku weakley hugged back before he hugged a little tighter.

Izuku :,,This isn't a dream?"

Rei :,,No.... no..... you are free."

Tears came to Izuku's eyes before he buried his face into Rei's schoulder and started to cry. The heroes of the Justice League left the room, they could talk to Izuku later what the boy needs right now is his family..... his true family.

1 hour later:

Natsuo :,,So you are a merman now?"

Izuku :,,Kind of looks like it, am I stuck like this?"

He asked while pointing at his tail.

Nezu :,,No according to youre files you can transform back to having two legs or you can transform into a serpent."

Nezu stood on the bed besides Izuku as he put his paw on Izuku's shoulder.

Nezu :,,Imagine of having legs again."

Izuku closed his eyes and concentrated but nothing changed and Izuku slightly began to panic, but Nezu calmed him down saying.

Nezu :,,It's okay... take a deep breath and concentrate."

Izuku closed his eyes again and took a deep breath in and out, in and out and as he opened them again he had legs again he smiled and let out a relieved breath until he realised that he was naked he quickly took the blanket from the bed and covered himself while the others in the room started to laugh while Izuku blushed embarrassed but soon giggled himself a little bit. They continued to talk and Izuku asked them what happened in those years while he was gone but their reunion was cut short as someone opened the door, the family looked over and saw that Batman, Superman and Aquaman have stepped into the room.

Batman :,,We are sorry to interupt but we need to talk to young Izuku here."

Endeavor :,,Has it something to do with the thing you talked earlier about Izuku going with you."

Superman :,,Yes."

Aquaman :,,He is part Atlantian now and a big part of his powers are based on water."

Batman :,,Not only that besides Martian Manhunter the only one who can help Izuku in case he gets out of control and help him with his powers is Aquaman here."

Izuku :,,What does that mean?"

Superman :,,We mean that you should go with Aquaman to Atlantis, it would be the best place for you to get control over youre powers."

Batman :,,It would also be the safest place for you to be since the villians can't reach you there that easily."

It was silent in the room as Izuku just looked at the heroes and then at his family members in the room.

Aquaman :,,Of course you also can stay here if you want."

Izuku :,,........."

Gran Torino :,,Can you promise me that those who hurted Izuku can't reach him there?"

Aquaman :,,I promise."

Mitsuki :,,We just got him back......"

Masaru :,,Honey it's up to Izuku if he wants to go."

Endeavor :,,We are happy with youre decision equally what you choose."

Rei :,,Yes we are still youre family and always will be."

Tears came out of Izuku's eyes as he started to cry again as he  then was hugged by his family again, he was sad to leave them so soon again but was also happy that he always will have them as family.

3 days later:

Today was the day were Izuku was able to leave the hospital and he was happy about it he smelled medical supplies for years now and he was happy that he finally could breath fresh air again. Right now he and his aunties and uncles, Fuyumi and Natsuo were on their way to the place were the league was supposed to pick Izuku up. 

Natsuo :,,It's sad that you are already leaving us."

Gran Torino :,,I have to agree but it's for the best until we capture those villians."

Endeavor :,,I am sure that you will love it in Atlantis."

Mitsuki :,,And you should have no problems with finding new friends there."

Izuku :,,Are you sure?"

Masaru :,,Of course we are sure!"

Izuku nodded as he was getting more and more nervous as they came nearer to the place were the league was about to pick him up.

Fuyumi :,,It is kind of weird that Aquaman said that you don't need any things."

Natsuo :,,Fuyumi I don't think that he can wear normal clothes underwater."

Aizawa :,,Right and I am sure that Aquaman prepared some things for him already."

Just then they reached the location it was in a park and as they walked in they already could see Aquaman standing there surrounded by fans who wanted his autographs or pictures. Izuku and the rest of his family decided to stand back and wait until the fans were gone after that Aquaman approached them.

Aquaman :,,Sorry for the wait I didn't expected to be that popular here."

Natsuo :,,All heroes of the Justice League are popular here."

Aquaman :,,I saw that anyways....."

He looked at Izuku.

Aquaman :,,Are you ready Izuku?"

Izuku just nodded and then turned to his aunties and uncles before hugging them as they wished their goodbyes.

Aizawa :,,Watch out Problem Child."

Izuku nodded and then turned to his last uncle.

Nezu :,,Izuku..."

Izuku got on his knees and hugged Nezu as Nezu hugged back tightly before letting go.

Nezu :,,Izuku remember what I said, scars aren't always a bad thing, it means you survived."

Izuku nodded before hugging Nezu again, they hugged each other for a couple of minutes before they let go of each other. Izuku stood up and gave a determined nod to his uncle and the others before turning to Aquaman.

Aquaman :,,Are you ready?"

Izuku :,,Yes, goodbye everyone."

All :,,Bye."

Gran Torino :,,And call us from time to time!"

Izuku :,,I will!"

Aquaman turned around and walked towards the lake followed by Izuku as they stood infront of it a portal opened and Izuku flinched backwards.

Aquaman :,,No fear Izuku this is a Zeta tube this will bring us to Atlantis."

Izuku nodded before turning his head towards his family again he waved at them and they waved back before he closed his eyes and followed Aquaman into the portal.

Izuku felt as if he was flying or something, he opened his eyes and saw that they weren't on the surface anymore they actually were in somekind of cave underwater. He saw Aquaman swiming infront of him motioning him to follow, Aquaman then turned around swiming towards the entrance of the cave. Izuku swam after him what actually wasn't as hard as he thought but it felt weird breathing through his gills. Izuku saw that Aquaman was far ahead of him so he decided to transform into his merman form to see how fast he was with it and to say the least he was alot more faster then before, he then stoped besides Aquaman at the entrance.

Izuku :,,Wow"

Aquaman :,,Welcome to Atlantis Izuku youre new home."
