"This one is far too weak. Stick him with the others."
Contempt on his face, the man handed the smaller of the twins back to his wife, opting to pick up the larger of the two instead.
"You, you will be the one to surpass not just me, but to surpass All Might as well."
Raising the infant into the air, the father grinned, marveling at the thin sheet of ice encroaching on his finger.
That sheet of ice then melted as small wisps of flame shooed it away, warming the digit once more.
"B-But dear, what of his twin?"
The father cast an irate eye at his wife, causing the woman to flinch as she shielded her child with her body.
"Do whatever you want with it. From the looks of it, his twin took his quirk for his own."
The thought brought a deeper smile to the man's face as he raised his son higher, pride swelling deep within him.
"Isn't that right, my son? You took your twin brothers' power all for yourself, didn't you?"
With a hearty chuckle, the man handed the baby off to a nurse, intent on returning to his duty.
Before he could, however, the mother of his children posed another question, said inquiry spoke far more quietly than before.
"What…what do we name him?"
"Call him whatever you please. He, much less his name, has no value to me whatsoever."
Turning about face, the man walked out of the room, leaving the mother of his children alone in the hospital bed.
Bringing the child closer to her chest, the woman allowed a small smile to grace her face as she placed a small kiss atop her child's head.
"I think I'll call you,"
"Izuku!"
The teen jolted awake, the flames he perpetually kept on the tips of his head flaring as he did so.
"I'm up, I'm up!"
With a giggle, the second greenette of class 1-A pointed to the aforementioned flames as an inquisitive look graced her eyes.
"I wanted to ask you, are you related to Endeavor in any way? Your quirks are eerily familiar."
The question inspired a chunk of 1-A to jump in as well, glad their speculations were at least somewhat rational.
"Yeah! I didn't wanna sound stupid by asking but you and the number two's quirks seem the same."
"You're always stupid, shitty hair!"
"Point taken but still, are you his secret baby or something?"
The bus fell silent for a few moments before a loud huff filled the air, a small stream of flames exiting the nose of the sounds originator.
"Not at all."
A round of disappointed "awes" filled the space.
"So if you aren't related to Endeavor, who did you get your quirk from, Ryukyu?"
A hearty laugh cut through the air as Katsuki threw his head back, a result of what he believed to be a dumb question courtesy of Mina Ashido.
"No, idiots, Deku gets his quirk from his dad. It's an evolved version of his old man's fire-breathing, one that lets him produce fire from everywhere, not just his mouth."
"Then what about him using Prominence Burn? I thought that was Endeavor's move."
It was now Izuku's turn to explain as he locked eyes with Sero, the one who spoke the question.
"It is his move. Ever since I could remember, my dad taught me that our flames are a part of us and that we need to treat them like partners and not just tools. The way Endeavor uses his flames isn't right, he makes them look evil and malicious when, in reality, they're a beautiful something that should be treated as such. When I use Prominence Burn, its as a way to remind myself and others that these are what flames are, this is how powerful your flames can get when you treat them with passion instead of anger."
This time, the bus was filled with a chorus of "ohhhs" as the students accepted the explanation.
All save for Shoto Todoroki.
"Those are real villains!"
Shota yanked the capture weapon free from his neck before turning to the pro hero beside him.
"13, make sure the children are safe, I'll handle this-"
"LIKE HELL!"
The voice came from two different sides of him, from two entirely different people.
Yet Shota Aizawa knew the two shared the exact same goal.
Izuku and Katsuki cleared the homeroom advisor, their quirks already dancing around them as they yearned to be released.
"Midoriya, Katsuki! Both of you stand down! These are real villains in front of us-"
"And they're about to get a real ass whooping, right Kacchan?"
"You better fucking believe it!"
Without another word, the two headed into the mass of villains, flames, and explosions flooding the space.
The shorter teen threw a right leg switch kick, shattering the ribs of one of the villains before sending a palm strike into the man's chest, a torrent of flame following it.
Dragging his heel on the ground, the teen turned 160 degrees while raising the limb before dropping it like an ax atop the head of another villain.
"DIE!"
The voice of his best friend filled the space before a massive explosion followed it, the force of which knocked out 7 villains cold.
"So that's how you wanna do it."
With a grin, Izuku ran toward a group of villains before leaping high into the air, flames accumulating around him.
The teen then threw his body forward, rotating it like a wheel as he began to fall toward his foes.
Who began to run in the opposite direction.
However, the effort was far too little, far too late as the heel of the teen's foot collided with the ground, sending a massive wave of flames that slammed into the group, concussing them while lighting them aflame.
By the time the two were finished, the once terrifying army of villains was reduced to little more than a disorganized group.
And what little remained did not want to fight the duo.
"What the fuck is UA feeding their students?!"
Turning toward the man made of mist beside him, the ringleader issued a single command.
"Fuck these guys, bring in the Nomu."
"As you wish."
Dread.
It's what filled the air as the mist man spat out a hulking, deeply purple beast that seemed larger than even All Might.
"Kill the teacher then kill the two brats in front of him."
There was no nod, no grunt of approval, or anything of the sort.
Only the sight of a massive fist entrenching itself in the stomach of Shota Aizawa.
The man seemed to fold in half as his torso wrapped around the beast's hulking fist, the force cracking his sternum and stripping his lungs of air.
Shota flew backward as blood flew from his mouth, a fragment of bone potentially piercing his organs.
The pro rose to his feet, bringing his quirk to life in an effort to strip the beast of its quirk.
"Don't bother. This creature was designed with the express purpose of killing the Symbol of Peace. Not only does it possess strength surpassing that of All Might, but it wields both Shock Absorption AND Super Regeneration. That quirk of yours only takes one of the two."
The pro was given no chance to process the information as another blow courtesy of the Nomu met his body, threatening to pacify him upon contact.
"Just accept your death, Eraserhead. You have no hope of beating All Might which means you have no hope of beating my Nomu."
The blue-haired man then dragged his thumb along his throat, signaling to his creation to finish the job.
The creation appeared before Shota, its massive fist reared back as it prepared to decapitate the pro with a single strike.
"HRAH!"
A wave of searing hot flames collided with the fist, knocking it upward and out of range of its target.
"Kacchan, grab Aizawa-Sensei and take care of that handjob-loving freak. I've got this guy."
A choir of explosions sounded off as Katsuki darted toward his homeroom teacher, a half smile half grimace on the blonde's face.
"I'll listen to you this time, Deku, but don't make a habit outta telling me what to do!"
Grabbing the man, Katsuki used his right hand to propel himself away from the fight that was sure to follow.
For a brief moment, the Nomu turned toward the fleeing blonde, intent on catching the boy and executing his homeroom teacher.
"Nomu, kill the fire brat first. Maybe if I kill some kids, All Might'll come out of hiding."
The acknowledgment came in the form of a lethal overhand, one that threatened to take Izuku's head off his body had he not jumped backward.
Righting himself in mid-air, the teen sent out a fireball from his fist, the attack hurtling toward the beast's head.
As though it wasn't there, however, the Nomu simply ignored it, continuing to pursue his new target.
The aforementioned target created a wall of flames, raising them to their maximum temperature in an attempt to stop the advance.
It didn't work.
Instead, the creature charged through it, slamming a fist into the teen's chest which sent him flying backward.
Pushing flames to his feet, the teen righted course, narrowly avoiding the follow-up hook that sought to remove his head.
Dropping low, Izuku wrapped his palms around the beast's knees, sending a torrent of flame through them and into the creature's legs.
The attack was somewhat effective, stripping the Nomu of its flesh right down to the bone, a fight-ending injury.
Had it been permanent.
Right before his eyes, Izuku watched as the beast regenerated its flesh, a testament to the raw healing capabilities of super regeneration.
Jerking the knee upward, the Nomu slammed it into Izuku's stomach, sending him flying backward and onto the ground.
Rolling to the left, the greenette avoided his opponent's attempt to cave his skull in before rising to his feet and clapping his hands.
The resulting wave of flame blinded the creature, causing it to stumble back as it struggled to regain its vision.
The teen then took his chance, running up to the beast and resting the tips of his fingers against its chest.
"Threads of Flame."
The attack took the shape of its moniker as condensed flames thinned out into thread-like wisps before passing through the Nomu.
The creature halted all movement as blood leaked from its chest, the beast's pulsating eyes rolling into the back of its skull.
"Nuh-uh. He's not finished yet."
As though brought back to life with those words, the Nomu jerked, the thin wounds on its torso closing as it focused its sight back on its opponent.
"When I said Super Regeneration I meant Super Regeneration. Before his brain stopped working, my Nomu put his quirk into overdrive, repairing his heart before you could fully burn it."
"No fucking way."
"Way. Now be a good student and die."
At the mention of death, the Nomu kicked its foe in the stomach, causing a massive wave of blood to flow from the teen's mouth.
Cocking its fist back, the creature aimed it at the teen's skull, intent on caving it in and killing his target.
But once a fist, wielding strength comparable to its own, slammed into it, the Nomu was sent reeling back.
"I was wondering when you would show up, All Might."
"You broke into the school, ambushed my students on a field trip, left a teacher in critical condition, and attempted to kill one of my students."
"I was in a silly, goofy mood."
With a grimace, All Might created a tight fist, rage bubbling inside him.
"That mood ends right here, right now!"
"Nomu, you know what to do."
The beast instantly switched focus to its true target, throwing a blisteringly fast right straight toward the Number One's head.
The aforementioned Pro slipped the punch, responding with a mighty right uppercut that buried itself into the beast's stomach.
Leaning back, the man narrowly avoided the right hook aimed at his head before responding with a left jab followed by a right overhand.
Each punch landed true the force of both briefly stunning the creature.
But that was it.
"This…thing is able to keep up with me?! How?!"
"With Shock Absorption and Super Regeneration."
Slamming a right body hook into the beast, All Might slid back, allowing himself time to study the creature before him.
"Shock Absorption and Super Regeneration you say? Well, that just means I'll beat it faster than it can regenerate!"
Throwing a jab, All Might stopped the motion half way before tackling the creature and slamming it into the ground.
"DETROIT SMASH!"
The attack connected beautifully, causing the beast's eyes to pop as its head caved inward.
However, what relief All Might felt was short-lived as the beast bucked its hips, throwing the Pro off of it.
"I don't think any of you really grasp the super in Super Regeneration."
Rising to its feet, the Nomu healed its sunken in skull, making it seem as though it hadn't been attacked at all.
This, paired with his shortening breath, began to sow a seed of dread into the Number One Hero.
Bringing his hands up, All Might grimaced as he prepared to exchange blows with the beast once more, a part of his mind screaming futility.
However, All Might wasn't one to give up, not even in the face of overwhelming odds.
And neither was Izuku Midoriya.
"THREADS OF FLAME!"
Thin strings of flame pierced the Nomu's eyes, melting the sensory organ and blinding the beast once more.
"Young Midoriya-"
"SHUT UP AND PUNCH IT!"
"Er- Right!"
Stepping into the beast's guard, All Might reared his right fist back at the hip before snapping it outward.
"TEXAS SMASH!"
The resulting wind pressure was like a vacuum of sorts, tearing out chunks of flesh from the beast.
Chunks that quickly healed.
The beast grabbed the sides of All Might's head, it's eyes still in the process of regenerating, before leaning back.
Before the Nomu could execute the headbutt, balls of flame slammed into the partially healed eye sockets, reverting what progress was made and sending waves of pain into the creature.
"HIT IT AGAIN!"
Leaning forward, All Might took a step forward, making sure to put his entire body into the right overhand he was about to throw.
"DETROIT SMASH!"
The punch hit lower than it normally did, colliding with the beast's sternum as opposed to its skull.
The result was still the same, however, as bone shattered and flesh tore.
It was in that instance that All Might understood what his student was doing.
"By constantly damaging the Nomu's eye, Midoriya is forcing it to focus its quirk on regenerating its sight which means it can't properly focus on what I'm doing to it!"
A smile now firmly back on his face, All Might went to work, landing blow after blow on the Nomu, each punch stripping the creature of its ability to heal properly.
Simultaneously, Izuku was launching wave after wave of fire, ensuring that the beast's eyeballs were nothing save for goop during the length of the fight.
However, their breakthrough was short-lived as All Might made another realization.
"It's still not enough! I need more, MORE power!"
Using his shoulder to push the beast back, the Number One Hero gathered every ounce of strength he had into his right fist as steam began to leak from his pores.
"Aweee, you're using your final attack? News flash, it still won't be enough to beat my Nomu!"
Cackling, the ring leader watched as his beast began to regenerate fully, the once constant flames stripping it of its vision now gone.
"Then I'll just have to BEYOND!"
Kicking off the ground, All Might rushed the beast, power emanating from his fist.
The Nomu did the same, ready to tank the attack before killing its target.
"DETROIT! SMASH!"
His fist met the fist of his target, putting the two in a struggle for power.
A struggle the Number One Hero was losing.
His fist being repelled and his body rapidly weakening, it seemed as though the Symbol of Peace was doomed for death.
Until a bloodied palm rested itself against the creature's torso.
"Promince Burn."
Immediately, a massive torrent of flames flowed from the boy's palm, each stream differing in color and shade as they wrapped the creature in pure, raw, beautiful heat.
Once the flame died down, the blonde Pro Hero was both grateful and fearful of the result.
What once was a beast even he struggled to match.
Was reduced to nothing but ash.
SonicMax: interesting. also thank you for just getting to the meat of the story. so many of these get bogged down by starting early.
Ant: It felt better to give Izuku's past in increments rather than just starting from the beginning.
AlexanderHalsen: very excited to see where thos goes and if the pairing isnt Izuku and Kyoka id like to see Izuku paired with Mei
Ant: I don't really see Izuku needing to interact with Mei but if you have ideas that would develop their relationship I'd be happy to hear em.
Guest: Not a harem of every female known to exist; but Ochako, Jiro, or Both with those two being it/finito?
Fine with all that.
Ant: I don't write harems.
Guest 2: Kyoka and Izuku? Fine with that. Can already see him adding some pyrotechnics to a jamming session.
Ant: You see the vision.
Guest 3: Looking forward to a lot of sources of inspiration.
Fire Bending of all kinds, Extremis from Iron Man 3, Human Torch, Father from Codename Kids Next Door, etc to name a few.
Ant: I know one of those characters.
TheRealShenron: suggestion for some more sources, ifrit and phoenix from final fantasy, flames of rebirth, hellfire, revelation, crimson rush, radiant plume
Ant: I'm only really gonna take inspo from one specific series because it's important to Izuku's quirk and how it develops.
Fox Sage 1: Update please
Ant: Ok.
