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.

Author Notes: when you see the number 101, don't read it as one hundred and one. Read it more as one O one. The abilities that I have given Izuku are of my own creation or inspired by different anime and cartoon shows. Also shall I have All Might give his powers to Miro or shall he keep his powers. Right know for this story as this moment, All Might still has One for All even after his battle with All for One.

Rescued

Subject 101's screams echoed through the lab. The scientists poke and prodded the demon running test after test. They still was no closer to finding out why out of one hundred and one children this one managed to survive and none of the others. What made this one so special? They still didn't understand why the subject still retained some of memories. Even though the demon could no longer see the boy's face, he knew that this person was very important to him so he held onto what little memory that he had left. Also every time they mentioned or brought up the subject of All Might, Subject 101's powers would activate going out of control. They had no idea why it happened. As for Subject 101's mind set a part of him wanted to kill All Might while another part of him worshiped the hero and wanted to be like him. It confused Subject 101 so that was the reason behind the power surge and why his powers went out of control.

Meanwhile... the hero Eraserhead was scoping out what looked to be an abandoned building. He could see various high tech devices being brought into the building. The people whom came and left all wore lab coat's. Eraserhead tapped his ear piece as he wore a wireless walkie hidden in the capture tape that he wore wrapped around his neck.

"This seems to be the place. I am heading in. Stay on guard and wait for my call." Eraserhead stated.

"Be careful Shota. You have no idea what lies within." replied a voice over the walkie. Shota Aizawa siad nothing as he snuck inside using a vent. Aizawa crawled silently through the ventilation system. He could hear what sounded like muffled cries and whimpers. 'Is there someone still alive?' Aizawa thought to himself. He followed the sounds down to the dark and dank basement.

Thirteen years had passed since the mass kidnapping on one hundred and one children. All of the proheroes felt frustrated when it came solving the case. One hundred dead bodies had turned up as all of the kids no longer looked human anymore or even resembled something even remotely human. All of the children whom bodies were found showed signs of having or being given multiple quirks. Some of the children died instantly while others it took longer. Aizawa still had hope that one of the children was still possibly alive. Aizawa dropped out of the vent when he reached the end. He landed in front of what looked to be a cell that was designed for inmates. It had only a small window which would allow people to look in or out from. The muffled sounds seemed to be coming from that room. Aizawa removed his goggles allowing him to see better into the room. Aizawa removed his goggles allowing him to see better into the room. What he saw made him gasp in shock. What he saw was a young looking teenager chained to the walls. A mask covered most of his face while white hair looked caked with dirt and blood. Aizawa could see two demonic horns that emerged through his hair. when the being within the cell heard Aizawa gasp, he lifted his head to show his glowing blue eyes that rested in a sea of black. The being in the cell rattled his chains as he tried to get to the door. Aizawa could tell that this demon looking human was hurt and needed help.

"This is Eraser... I found a survivor. Raid the building and arrest everyone. I want someone to get all the files and any data of what was going on." Aizawa stated as he spoke into his communication device.

Suddenly the building began to shake as Aizawa could hear All Might's booming voice. The being in the cell began to stir wildly. Aizawa could see a power inhibitor collar around the demon's neck which prevented his powers from acting up.

"All Might... Do not come down here. It seems much like the Nomu, this person was drastically altered to fight against you."

"Do you think that the league is behind these abductions?" asked All Might through the communication device.

"I am not sure. The being that I am seeing looks nothing like the Nomu. He looks still remotely human." replied Eraserhead. Aizawa reached into his pockets taking out his lock picking tools. "Calm down... I am here to help you." he told the demon. Aizawa heard soft whimpers in reply as he heard the chains rattle away from the door. Aizawa knelt before the door as he began to pick the lock. Over the communication, devise he could hear the battle that was going on above him. He could hear a female begin to speak over the intercom.

"Attention all crew... The pro-hero are here. Someone go and get Subject 101. This maybe the only chance we have get to get actual data!"

Aizawa knew that the scientists where heading down to where he was at. He decided to use this to his advantage to get them to unlock the cell. Aizawa quickly hid from view as two scientist came rushing into the area.

"Hurry Doctor Gother wants Subject 101 to deal with the heroes. She can only hold back the pro-heroes for only so long." stated one of the scientists. Eraserhead took this chance as he knocked out one of the scientists once they unlocked the demon's cell. His binding scarf wrapped around the other scientists. The demon watched as it seemed that he could tell that Aizawa were here to help him. Plus there was the fact that he didn't resemble or look like any of the people he had seen within the lab.

"Undo his chains and bindings but leave on the power inhibitor." Aizawa commanded.

"Eraserhead. But how did you get down here?" asked the scientist that he held hostage.

"It doesn't matter. Do as I say and don't bother trying to use your quirk." The scientist obeyed Aizawa's commands.

Once free from his binds and chains the demon slumped to the ground unable to support his own body weight. Aizawa rushed into the cell after knocking out his hostage. The demon looked beat up and almost drained of energy.

"Kacchan?" the demon questioned.

'Is that a name of someone who he once knew? Is it possible that some of his humanity still remains intact?' Aizawa thought to himself.

"This is Principal Nezu. Eraser... I have gained the information that you requested. Have you rescued the being in question?" asked a small voice.

"Eraser here... I have the subject in question but, it seems that he has seen better days. I am going to need help bringing him to the hospital."

"I am on my way." replied All Might.

"Wait... All Might..." called out Shota but All Might broke communication. "God damn that man. I can never understand what goes on in his mind."

"Kacchan...?" the demon asked.

"Don't worry... I will find out everything I can to help you recall who you once were. Work with me until then." Aizawa asked.

"Hero... help save me?" the demon asked.

"Yes... I am here to help you." Aizawa stated holding out his hand to the demon. The demon nodded as he took Shota's hand as a soft smile appeared behind the demon's mask.

"Thank you."
