Over time Izuku met the class, and they all wanted to protect the small broccoli boy. Izuku didn't have all the same classes or didn't even have classes during the entire school day. He was given a workshop to build and repair the equipment he uses. He had a newly issued hero license so he could leave and legally do hero work. He was dropped a lead on the league of villains by one of his informants.

            He was meeting up with another informant to confirm the info on where to find the league of villains. He had a terrible gut feeling and made sure to check that the tracker on his neck was active. He was trusted to not have a tracker anymore but he felt safer with one so he designed on into a choker so it was more discrete and lightweight. 

            As he arrived at the destination of the meeting two portals opened on either side of him. out of one portal handy man stepped out, and out of the other, a Nomu with dragon-like features stepped out. Izuku had his katana in hand, the other hand pressing the distress signal on his tracker.

"Alpha! So great to see you alive! We thought you died from the last Nomu's attacks. Maybe we ca...." The Nomu interrupted him by launching itself at Izuku. 

Izuku had barely any time to react. He swiped his blade at the Nomu while using the wall to launch himself over the Nomu. His katana was ripped from him and he was quick to grab his other and cut the beast. The Nomu's tail quickly wrapped around his torso slamming him into the concrete and pinning his arms. 

          Shigaraki was confused until his sensei's warning rang throughout his mind.

"Shigaraki, this Nomu's quirk may make him get attached to someone. Be careful."

A smile formed cracking his dry lips. The Nomu's long tongue wiped crossed the visor, as Alpha made a sound of disgust. Alpha tried breaking away from the Nomu. The Nomu simply wrapped the end of his tail around his arms before picking Alpha up by the back of his uniform. Shigaraki examined Alpha. He lifted his head up to look at him when Shigaraki noticed the tracker. He placed his five fingers on the choker, disintegrating it.

"Nomu, take Alpha back to base. Return to your cell with him." Shigaraki told the Nomu and the portal began to open. 

Nomu walked through with the struggling Izuku and Shigaraki. Nomu followed orders and brought Izuku to his cell and dropped him when the door shut. As the Nomu went to eat whatever was dropped into the cell, Izuku reached for the distress signal in his helmet he used only for emergencies. It was the one that was connected to Stain's phone. What he didn't know was there was a signal jammer stopping his signal.

            As Izuku hit the button, the Nomu noticed that Izuku was moving. He squached and Nomu launched forward grabbing his hand. Nomu dragged Izuku to a pile of pillows and blankets that acted like a bed replacement. He placed Izuku into the pile before sitting on the edge of the pile, staring at him. Izuku slowly backed away into the corner as the Nomu stared at him. Izuku felt terror enter his heart. How long until this beast gets bored and kills him? He already thinks Izuku was a toy he can have. 

          The door opens making Nomu and Izuku look towards the door. The Nomu's tail began wagging at the man. He was a man in a mask and suit. He approached the two in the corner and pet the Nomu on his forehead. The Nomu quickly grabbed Izuku and held him in his arms like a child trying to show their parents a new toy. 

"So he decided to get attached to you Alpha." The masked man said. 

"You seem to know my name and what I look like, but I don't know who the hell you are." Izuku snarled back which caused the Nomu to pull him into his lap protectively.

"My name is All for One. I have seen you and your quirk. You have interested me. Now that we have you contained and out of the way, you won't need your quirk anymore." The man stated with amusement in his voice.

He reached out and grasped Izuku's shoulder. His hand shifted in confusion before the grip tighten. Izuku tried to rip his hand off only to find that Nomu at some point had his tail on of his hands. A sudden feeling of something being pushed into his very core overcame his body. Pain spread throughout him the longer the man's hand was on his shoulder. His vision began to swim making him feel sick. The man's grip tightened and Izuku groaned out in pain. The man's hand loosened and he pulled his hand back. The Nomu suddenly slammed his tail into the man as he felt the feeling of sickness waft off Izuku. 

"Now maybe you'll be able to last a decent time with this beast." The man said laughing at the figure slumped in the Nomu's arm before he left. Nomu gently laid Izuku into the pile as he remained limp. The beast gently rubbed the next of Izuku, as his tongue slipped into the exposed part of his shoulder to try and nurse the forming bruises. Izuku lost consciousness as Nomu curled around him. 

           Izuku woke up to being carried in the Nomu's arms as he followed Shigaraki. Izuku tried moving when he heard a chain rustling. A chain linked Izuku to Nomu and Shigaraki's wrist. The Nomu noticed Izuku awake and licked his helmet. Shigaraki glanced at the two as Izuku was trying to wipe off his helmet. Izuku was placed down as his chain was yanked towards a corner. 

"Alright brat, we have things we need to take care of. Cause Nomu any troubles and I will personally cut your fingers off and watch them slowly grow back." Shigaraki said as he disconnected the chain connecting Izuku to his wrist. 

Izuku was dragged into a portal by the Nomu before he was picked up by him again. Izuku saw that they were now in a forest. The fire was covering trees and bushes. The Nomu wrapped its tail around Izuku's arms painfully as he took off in the air, causing Izuku to cry out in pain. The Nomu landed on the cliff to check on Izuku. Izuku noticed a kid who was getting backed up to the edge of the cliff by them. He took that moment to grab the kid. 

          The kid screamed and panicked as the villain in front of him yelling at him. The Nomu was not happy about Izuku grabbing the child and tried to get him to let go. Izuku curled up around the child to protect him from the Nomu's claws. Nomu's claws sometimes cut into Izuku as some pieces of his uniform were torn into and through the small parts that already were exposed. Izuku moved the chain in a split second so the Nomu would break it, and the villain choose that moment to attack Izuku. 

          When he went in for the attack, he hit the Nomu and enraged the Nomu. Izuku used the time of their fighting to escape with the kid. The kid tried to break free again once they were no longer curled up. The child snarled at Izuku multiple times.

"I don't need a stupid hero's help!" He yelled at Izuku.

"I'm no hero kid. I am a vigilante and we need to get you somewhere safe. Before that beast realizes I'm gone." Izuku replied quickly. 

A familiar roar echoed through the forest.

"Shit, we are running out of time," Izuku said before he suddenly ran past Eraserhead. 

"Where have you been!!" Eraser yelled.

"Very attached Nomu. Found the kid getting cornered." Izuku stressed before a loud crash and rumble erupted from behind him. 

"That would be the attached Nomu." Izuku grimaced.

Izuku glanced over his shoulder to see the Nomu. He threw Koda to Eraserhead before he suddenly was flying from a tail slamming into his torso. 

"Alpha!" Eraserhead yelled as Izuku went flying into the trees. 

Nomu launched after the vigilante who was sent flying through now broken trees. Izuku groaned in pain before the dreaded tail wrapped around his torso lifting him up. Izuku's visor was cracked and flashing warnings as they showed many broken bones. Izuku tried to get out of the Nomu's grip as the Nomu screeched in glee at having his toy back. Nomu tightened his grip when sounds of explosions came from nearby in the forest grabbing Nomu's attention. The Nomu moved quickly to where the explosions were. He saw the boy who made the explosions and a sparkle appeared in his eyes. The Nomu took no time to pin the boy down while slamming Izuku against the ground on accident. Izuku groaned in pain. Nomu lifted his tail to check on him. Nomu licked the cracked visor and whined when Izuku didn't react. 

           The Nomu felt explosions on his scales and turned his attention off its injured prisoner. He smelt the boy, before licking him and picking him up. when he went to take off into the forest ice encased the beast's legs. 

"Put those two down!" Someone demanded of the beast. 

The Nomu looked at that somebody. The same sequel that Izuku knew was for when the Nomu got excited about his toy sounded from the creature. Izuku tried to move but his body refused as the beast moved to grab the unlucky hero. The boy tried to keep the ice on the beast but the beast easily broke it. Using his free hand not occupied by the swearing explosive blond, he grabbed the new boy. He screeched happily before returning to Dabi for the portals to open. As the Nomu stepped through the portal Eraserhead arrived just too late to save his three students. 

           When Nomu passed through the portal, Shigaraki tried to approach and take the blond. He received a loud snarl alerting him.

"Great! You got attached to the target. Sensie only said you'd get attached to one person!" He whined and yelled like a child.

Nomu was ordered to his cell, who gladly returned to his cell. Once the room locked the Nomu released the three. Unlike the other two who staggered to stay on their feet, Izuku just dropped to the floor. He fell face first causing his visor to fully break and a chunk fell to the floor. Nomu looked at Izuku before gently wrapping his tail around his wrist. It gently lifted him until he was practically standing. The beast's massive fingers of its free hand wrapped under the helmet of Izuku, searching for the release button. Izuku gave the best attempts of trying to push the Nomu's hand away from his helmet, which was like a toddler trying to push a car until the sound of a click echoed in the room. 

             The two boys wanted to help but didn't want the beast to harm the injured vigilante more. The Nomu tried his best to gently pull the helmet off, and soon after sat down laying the vigilante into his lap. The beast's hand ran over his face and the Nomu licked its hand clean. Blood dripped from its hand. The beast had a look of concern over the injured vigilante. The beast continued to wipe the blood off and then licked his hand clean until he found the wound. It was mostly healed and the wound was slowly stitching itself closed. 

            Izuku was suddenly pulled from the Nomu and placed into the pile. The two boys cut the beast off from its injured prisoner. 

"You are Alpha? Would explain the sudden student in the middle of the year that was accompanied by staff all the time." Todoroki stated without looking at Izuku. 

The Nomu slowly got up and watched the three. The two boys tensed at the beast as it walked slowly towards them. The Nomu watched every movement by them as they got into a fighting stance. As the beast continued its approach, the two backed up till they were at Izuku's feet. The dull eyes of the Nomu glimmered as he approached them. 

          When the Nomu was about five feet away, the boys attacked. The Nomu grabbed them before throwing the two in anger. Bakugou was thrown away from Izuku as Todoroki was thrown above him. Todoroki hit the wall before landing on Izuku. Bakugou hit the wall and when he fell to the floor he did not get back up. Izuku was grabbed around the waist and ripped out from under Todoroki. The beast dragged Izuku into the center of the room as Todoroki ran to check on Bakugou. Izuku struggled to get free when the beast pinned him to the floor. Even with the pain of moving some parts of his body, Izuku continued to struggle until the Nomu added more pressure and claws found their way to his neck.

          The Nomu scratched his neck as he grabbed the collar of his armor and ripped on it. Todoroki tried to get to Izuku but the beast grabbed him and pinned him down with his tail. The beast continued to dig its claws into the armor tearing it off causing sparks and blood to slowly pool when the claws dig past the armor. The Nomu took one last swipe at what was left of the armor, claws going right through and into Izuku's torso. Izuku cried out in pain as the beast tried ripping them out. Using their other hand to hold his body down and rip them from the rapidly bleeding body. The beast slowly came out of its rage. It continued ripping chunks of the armor off and the claws entered his torso deeper than before. 

          Izuku screamed louder in pain as the claws slid out of his mutilated body. Todoroki continued to try and get to Izuku as blood poured from Izuku's body. The Nomu backed off his body and Todoroki rushed to his body. Todoroki was freezing the wounds shut. The Nomu tried to grab Izuku but ice blocked the two. The door opened showing the blood bath to the two that entered the room. 

"Oh my. Nomu must have gotten mad. Kurogiri the boys in Nomu's cell need medical attention. One more than the others and it looks to be Alpha." One of them said.

Todoroki was still trying to stop the bleeding as the ice was melting from the warmth of the blood and body. The two ordered the Nomu out of the cell.

"How do I get your armor off?" Todoroki asked. 

"The button on my neck if it's still intact." Izuku croaked out slowly.

A portal opened next to the two and out came Kurogiri. He had a scowl at first but saw the blood bath and started to move. Todoroki didn't notice him at first as he took the remains of the undersuit off the wounds. Kurogiri tended to Bakugou quickly before getting more urgent supplies for Izuku. He started removing the debris and checking the organs that were showing slightly. He carefully stitched the organs with tears and the wounds themselves. Gently wrapping the wounds he continued to other wounds on Izuku's body. 

              He double-checked over Bakugou frowning before he suddenly opened portals under the three. Todoroki landed in a hospital chair as Izuku and Bakugou both landed in hospital beds. Kurogiri pressed a button on the guard rail of the beds. A nurse walked in and saw the scene. She saw a villain that looked like he was holding down a very injured young boy. Kurogiri teleported out as the nurse called doctors and nurses. The doctors and nurses surrounded the three boys and as they checked them over a note was teleported into a doctor's face. 'A nomu tore his lower chest and torso open. If he was not a child he would have been left for dead.' The note read. 

               UA was contacted immediately and Izuku's body was properly taken care of and a breathing tube was down his throat. Todoroki was fine besides a minor concussion and bruises, and Bakugou had a major concussion and bruises. Bakugou was waking up. Izuku passed out from pain meds which he was very unhappy about. Todoroki was sleeping in the chairs when Aizawa arrived. He saw the sleeping teens and quietly sat in the other chair and also went to sleep.
