This is an AU My Hero Academia story in where Izuku is kidnapped and experimented on. I do not own the My Hero Academia franchise as it along with all of their characters belong to their creator Kohei Horikoshi. Warnings both Bakugo and Izuku may be a little OOC (out of character) so please don't hate. Please be sure to leave me your comments and reviews telling me what you think.

Reunion

"Have no fear for I am here!" cried out All Might as he barged his large frame into the small cell. A deep snarl escaped the demon as he wildly shook his head. Aizawa could tell that the demon was trying to restrain himself from attacking All Might. Aizawa stood before the demon as he pushed the large pro-hero out of the cell.

"You don't ever listen! I told you not to come down here! This being was created with possibly multiple quirks much like the Nomu. He was also programmed to fight against you. The collar that he is wearing is stopping his powers from acting up. I am a bit surprised that he has the willpower to not attack you!" Aizawa hissed at All Might. All Might sheepishly rubbed the back of his neck. Aizawa sighed out loud knowing the type of person All Might was. That's when Aizawa noticed that the number three pro-hero Hawks had come down as well.

"All Might, I will help Eraserhead. Why don't you go help round up the rest of the scientists." stated Hawks. All Might just nodded his head as he went back upstairs. Aizawa turned towards the demon as he looked more relaxed once All Might was gone. Aizawa went over and tried to help the demon up to his feet. Hawks sent some of his feathers to help since his six foot wingspan would take up too much space in a small confined area.

"Eraser lets take him out a different way so he doesn't have to see or run into..."

"Lead the way... Thanks for the help Hawks." Aizawa cut the pro-hero from saying All Might's name. Hawks nodded his head.

The two pro-heroes managed to sneak the demon out as they loaded him into an unmarked blacked out squad car. Aizawa got into the car next to the young teen whom looked a bit confused. He witnessed when got outside and into the sunlight.

'He's never been outside since possibly the day of his capture. Then there is that odd name he utters. Possibly someone he once knew. He looks about the same age as my third year students in my hero course. Maybe one of them might recognize that name.' Aizawa thought to himself. They brought the demon to the police station as they placed him a room where police could interrogate criminals as it had a one way glass that would allow people to see in but, the demon couldn't see anyone behind the glass. Aizawa couldn't help but to feel a close connection with the young demonic looking teen. Aizawa was in the room with him as the demon seemed at ease around the pro-hero. "Will it be all right if I remove the power inhibitor collar?" Aizawa asked. The demon slowly nodded his head. Aizawa walked up as he examined the collar figuring out how to turn it off and then he took the collar off the demon. The demon sighed in relief when the inhibitor came off. He hasn't realized how long its been since he had the damn collar off. A small knock came on the door startling the demon. He jumped back away from the door as he snarled loudly. Aizawa gently placed his hand onto the demon's shoulder as the creature turned his head towards Aizawa. The demon's eyes where glowing brightly. That's when Aizawa noticed some flecks of green in the bright blue eyes. "It's all right. I have to go to U.A. as I have classes to teach. But I shall return." stated Aizawa as he went and opened up the door to reveal a man who wore a brown trench coat and brown hat. Underneath the jacket he wore a standard business suit. "This is Detective Naomasa Tsukauchi. He will look after you while I am gone." The demon nodded his head that he understood.

Aizawa left the police station as he was given a file from Nezu concerning the demon they had rescued when he got into the car.

"What do you plan to do about that being we had saved?" Nezu asked.

"He doesn't seem to be a bad kid no matter how much they changed him to look like one. After everything that he has been through, he still retains some of his humanity. Plus it seems that he was able to recall a name from his past. I want to try to rehabilitate him and put him into the hero course." Aizawa stated as he took the file that was labeled "Subject 101." Once they got into U.A., Aizawa trudged into the classroom.

"Sensei... You're very late. It's not like you." stated the class president Tenya Iida. This caused Aizawa to sigh out loud.

"Sorry class. I just got done with a very important mission." he replied. Aizawa placed the folder onto his desk sighing softly. "I wonder who on earth this Kacchan person is." Suddenly a loud explosion rocked the classroom. Katsuki Bakugo stood up as his chair flew back.

"What the fuck?! Where in the hell did you hear that word?" Bakugo asked angrily.

"Bakugo... Language!" yelled Iida.

"Shut up Robotic Four Eyes!" growled Bakugo as he glared at the class president. Iida sat down clearly intimated by Bakugo.

"Bakugo... You recognize that name?" Aizawa asked. Katsuki could only nod his head. Aizawa pulled out a phone as he quickly called Nezu. "It's me. I found someone who recognized that word. Have Yamada take over my class." Aizawa stated. He didn't wait for as he grabbed the file that he placed down onto the desk. Katsuki quickly grabbed his stuff as he shoved them into his bag. Bakugo quickly followed Aizawa out of the classroom.

Bakugo wanted to ask Aizawa how he learned of his childhood nickname that only Izuku knew and gave him.

'It has to do with the mission he was on. Could it be possible that they found a survivor from the mass kidnapping that happened thirteen years ago?' Bakugo thought to himself. Bakugo wanted to ask Aizawa but he felt that he should hold off. The two arrived at the police station.

"Let's go Bakugo." Aizawa stated as he got out of the car. Bakugo followed behind as the two entered the police station.

"Eraserhead... I got the message. Here's a badge for your student. Are you sure about this?" asked Detective Tsukauchi. Aizawa only nodded his head. When Tsukauchi saw it was Bakugo it raised a whole bunch of questions. "It's nice to see you again Bakugo."

"Detective." Bakugo simply replied as he took the badge from the officer. The three of them headed back to a joint interrogation room. Beyond the double glass sat a boy whom looked more like a demon than human. There was something oddly familiar about the creature behind the glass. The demon seemed almost aware that he was not alone. He walked up to the glass staring at showing the few flecks of green in his eyes.

"Kacchan?" the creature questioned as he reached up taking off the mask that covered a part of his face. When the mask came off, tears sprung to Katsuki's eyes. A light dusting of freckles lined the bridge of the demons nose to his cheeks. Taking a closer look at the demon's white hair it was styled in the same way that Izuku wore his minus the horns.

"Deku..." Bakugo mumbled as the tears frantically ran down his face.
