Chapter Text
"He won't so long as he dodges!"
Those were the final words that Izuku heard before Katsuki pulled the pin on his gauntlet. As the explosion rushed towards him, he felt pain, unlike anything he had ever felt before. As he slammed through concrete walls, he felt rebar stab into him as his skin burned. His bones were broken all over and in many places stuck out from his flesh. His sight left him as he felt his legs shatter. Blood quickly began to fill his lungs as he finally stopped moving. The momentum of the explosion had nearly sent him outside of the training building with his head hanging out. Izuku's heart stopped beating as blood pooled around him.
"Young Midoriya! Young Midoriya do you hear me! My boy, please, say something!?" All Might's voice cracked as he saw his successor and son in all but blood lying on the ground surrounded by his own blood. Bakugou stepped out of the smoking hallway and stopped as he stared at the still body of Izuku twisted and broken.
"What!? Fuck! You just had to fucking ruin my chances you useless Deku!" He only cared that he would most likely be expelled from UA for what he had just done, not the fact that he just murdered someone in cold blood. Iida began to try and get Bakugou's attention to find out what just happened when a loud whine escaped Izuku's still warm corpse. His eyes once lifeless became a bright glowing green like a beacon. His broken body twisted and moved as in the distance an anguished cry could be heard. His body began to rise back to its feet as his bones continued to release sickening snaps.
"Deku, what's going on!?" The voice of Izuku's first friend in UA rang in his ear but all she got was a low-pitched groan as the now living corpse set its eyes on the person who killed it. A growl not unlike that of a wild beast escaped its throat as in a flash it punched Bakugou. The bones snapped with a sickening crunch as the green energy that came from Izuku's lifeless eyes began to glow from his open wounds. His body began to shift as the costume that his mother had made with love for him began to tear, destroying it further after Bakugou's attacks.
With small spurts of blood, the bones that had been sticking out of Izuku's right hand began to return inside the flesh as it mended itself into a twisted clawed hand. Izuku's mouth opened and with a screech that chilled everyone who heard it rushed forward and kicked Bakugou out of the building. His back began to shift and deform as his body pushed the debris that had been embedded into him onto the ground. Running forward with sickening crunches Izuku's living corpse headbutted Bakugou as he began to enter the building again. Izuku's left leg began to deform as it bent backward at the knee as his feet shifted, breaking his shoes as large talons replaced his toes with a new one growing at the back of his foot.
"What the hell are you doing ya stupid Deku!? Trying to play dead to fuck with me!? Well, it won't wo-" Izuku cut him off with a bellowing roar that could be heard for miles attracting the attention of many. Another roar louder than the one Izuku let out echoed in response. Izuku's shoulder blades snapped and broke as wings burst from his back with the sounds of tearing cloth and flesh accompanying it. Whatever was possessing Izuku's corpse gave them several experimental flaps as it walked towards Bakugou with its unhealed leg limping behind it. Tenya and Ochako came out of the training building only to stop dead at the sight before them. Their friend was twisted and deformed with limbs entirely foreign to his body that only minutes ago had been fine. The creature began to flap its wings and hovered off the ground. It growled at Bakugou and flew at him faster than he could react. With a clawed slap, Bakugou was sent flying across the ground before he began to roll until he landed in another building leaving a large hole in the wall.
More of Izuku's right arm began to twist and deform as it became longer. The skin began to blacken and grey with a ring forming on his forearm with several lines running all over it much like his changed leg and new wings. His jaw which had been dislocated in the explosion opened with a sickening creak as Bakugou came out of the building dazed. A shriek not unlike that of a massive bird of prey came hurling from his throat as he flew towards his target. As he flew, he tucked his wings in slightly and began to spin in the air like a moving drill with the two small spikes that rested at the elbows of his wings pointed straight at Bakugou. Before he could land his hit, All Might came rushing in and grabbed Bakugou out of the way. "Young Midoriya! Please, tell me if you can hear me!? Anything!?"
All Might got no response as Izuku's other arm began to shift and mirror that of his right arm. The long-muscled arms dangled in the air as Izuku's dead stare looked through All Might and at Bakugou who stood behind the number one hero much to his chagrin. "I can take care of fucking Deku!"
Before All Might could say anything in response Izuku flew at him. Before he would hit his mentor, he pivoted around him and kicked Katsuki with his broken leg. The bones snapped loudly, and Tenya felt sick. It began to mend itself as it mirrored his left leg. The fabric at the base of his spine began to shift as Izuku screamed to the heavens as he clawed at his head. All Might tried to go to his successor to help him but the suddenly grown tail knocked him out of the training city as Izuku's claws left marks on his head as ten horns began to grow from his head like a crown. His jaw placed itself back where it belonged as his teeth began to elongate and sharpen. Eraserhead, Midnight, and Present Mic ran onto the scene only to stop as they witnessed Izuku's body continue to contort as the pointed tail lashed out leaving small holes in the ground when it hit. The horns continued to grow as his face grew grey with hints of green where his freckles once were.
"Knew I should've expelled him." Aizawa lashed his capture scarf out and bound Izuku's arms and wings to his body. He fell to the ground with a thud as he continued to move erratically. The three heroes stepped forward, but they soon regretted that decision. Izuku's heart began to beat normally again as he vomited up the last of the debris that resided within his body. His eyes remained glowing as the capture scarf wrapped around him began to shift about. With a roar that could rival Yamada's quirk, his wings tore through the capture scarf as they grew four times their original size. Izuku's knees broke as his legs became ramrod straight. He bent his knees forward as he got up and then they bent backward once he was standing. Aizawa's capture scarf was useless now as the cloth fell to the ground. Izuku's eyes fell on the three teachers. He found his next targets.
Yamada let out one of his iconic sonic screeches at Izuku as Aizawa got his knife out. Izuku covered his ears in pain as they began to bleed slightly. The screaming stopped as Present Mic needed to take a breath but that was all Izuku needed to rush forward and kick the radio hero down the street. He knocked Aizawa back with one of his wings and knocked Kayama away with his fist as he turned his head every which way in an effort to keep track of all those who would attack him.
"Midoriya! Midoriya!"
"Midoriya!"
Tenya and Ochako tried to reach their friend, but they were pulled back by Present Mic as he let out another sonic blast at Izuku who screamed out in pain as he felt his ears rupture. Blood began to leak through his fingers and Yamada's eyes widened in horror. Before he could stop attacking though Izuku tore his ears off of his head with a pained roar. The two pieces of flesh fell to the ground as everyone looked on in horror at the self-mutilation. Tenya and Ochako wanted to go help him, but Midnight let out her sleeping gas before they could step forward. Izuku covered his mouth as he flapped his wings rapidly and dispelled the gas just as quickly as it had come. His glowing eyes narrowed at the Rated R hero before dashing forward and knocking her through several buildings with his tail.
Aizawa rushed forward with his knife at the ready to incapacitate his wings when Izuku pivoted and bit down on the knife shattering it. Aizawa was clawed in his face and one of his eyes was covered with blood. Some of the lines that ran all across Izuku's new body began to glow green as the rings on each of his forearms began to shift. Izuku disappeared in a blur and reappeared in front of Present Mic as he tore his Directional Speaker off of his neck. It fell to the ground in pieces as Yamada covered his mouth in fear of using his quirk now.
"Midoriya?" Izuku turned to the source of the voice to find Tenya and Ochako staring at him in clear concern. They began to step forward, but Izuku growled lightly. They stepped back and raised their hands placatingly and Izuku's posture relaxed. "We aren't going to hurt you." Tenya tried to assure him.
"Yeah, we just want to help." Ochako stepped forward carefully, not wanting to scare him.
As Izuku seemed to calm down Bakugou came barreling forward with his other gauntlet now full and ready to be used. "Don't think we're done yet Deku!" Before Bakugou could pull the pin and blow up the now much larger Izuku a large mass body slammed into him sending him flying. Izuku's ears which had regrown into more pointy versions of the original picked up small screams in the distance. Bakugou got to his feet in anger but stopped as he looked upon the woman before him. "Auntie?"
Inko Midoriya stood tall towering over all that was in her vicinity. She had four sets of horns with one set framing her cheeks while the other three of various sizes formed a large crown over her head. Her eyes which normally showed kindness burned with hatred as they glowed a faint green. She was well-muscled and sculpted like an Amazonian. She lacked the wings and tail that her son had but with how she held herself it was clear that wasn't a problem. "You dare to murder my son, force his true form to the surface, and for it to twist and deform his body. I should've killed you after the first time you beat him, laws of Lucifer be damned. I have ruined all those who dared to hurt my son and I will not stop now!" Inko raised her hand up and various demonic ruins began to appear as she chanted in a language unknown to all those present except for her. Before she could finish though she heard a loud thump as Izuku fell to the ground.
"Midoriya!" Tenya and Ochako rushed towards him as Inko's chanting stopped. Her eyes bore upon her son, and she rushed forward to look upon him.
"Oh, my sweet little angel, what has happened to you?" Inko looked upon both Tenya and Ochako for a moment before making a decision. A wide pentagram circle appeared beneath the group of four as it glowed red. "You two have been chosen by the Duchess of Fortune, a denizen of Hell, and advisor to Lucifer. Until my son is healthy you shall guard him and heal him. In return, I shall grant your families luck and fortune." Inko's eyes turned upon Katsuki who was frozen to the spot. "Know this Katsuki Bakugou, you may have an angel guarding you, but I shall tear their wings from their body and make them watch as I kill you. Your days are numbered." With a bright red flash, the small group disappeared leaving the rest to stare at the pentagram burned into the ground.
