96AN: Hey everybody. I wasn't intending to start anything new at this point, but I've been having a hard time getting motivation to write since my wife and I lost our pet. So, this piece is using a ship I'm quite fond of but not only haven't tried but haven't seen much. This first chapter is just to lay the groundwork, those coming after will be longer.
AN2: And to clear up any early confusion the Sludge Villain never encountered Izuku under the bridge, All Might just dropped the bottle after catching up to the guy.
The Four Sons (Working Title)
Chatper 1
-All Might-
The explosions shook the ground as All Might clutched tight at the lamp post as he trembled with pain and self-loathing at the back of the crowd. He couldn't see the Sludge Villain he'd allowed to get away anymore, but it didn't matter when he could hear everything.
The explosions from the boy being held hostage trying to get away.
The cackling laughter of the villain in question.
The heroes cursing their inability to deal with the situation for one reason or another.
And the civilians all loudly wondering 'How had this villain gotten away from All Might'.
"Woods!" a new voice shouted, startling All Might as the voice was determined, young, and distinctly unafraid. He couldn't see them, but their voice carried, "I can make you fireproof!"
"You're authorized, do it!" the wooden hero didn't waste a moment.
"It'll hurt and you'll still feel the flames." The young man's voice was still clear even as Kamui Woods let out a groan of pain before he leapt forward, All Might able to see him even from the back.
"UNHAND THAT BOY VILLAIN!" Woods roared, the jumping jubilant crowd shifting about enough that All Might got a glimpse of wooden tendrils forcing their way through the sludge and flames. Woods was roaring in rage and pain but pushed on in spite of it, the wooden fingers wrapping around the hostage and yanking the blonde boy out, one last powerful explosion from the now freed hostage splattering the sludge villain all over the road and walls from the force of it all.
Some of those watching were openly nauseous at the brutality of splattering someone, even if their body was liquid, all over a road. Others were just cheering for the already ending spectacle. With the explosions stopping, Backdraft was able to rapidly start making headway on the fires while Woods was depositing the snarling and thrashing ex-hostage with the paramedics.
"Thanks for the help kid." Woods's voice was still tinged with the pain of the flames as he approached whoever had used their quirk. With the crowds dispersing somewhat, All Might tried to subtly make his way further in, overwhelmingly curious about who the young sounding man was, "A quirk that makes people fireproof is an amazing power to have for a firefighter or support hero."
"Actually, that wasn't my quirk." The young man explained as a pit started forming in All Might's stomach, "It was my grandfather's. I was born with two quirks, one of which lets me give and take quirks to a limit." As the crowd spread somewhat more, All Might got a clear look at Kamui woods talking to a young man with snow white hair and distinct emerald eyes.
All Might felt rooted to the spot, unable to hear anything else over the screaming in his own mind, the light headedness from sheer shock. The boy, apart from those green eyes, could pass easily as a teenaged All for One.
-All For One-
"Oh, All Might, I do hope you're as foolish as you look." All for One chuckled to himself as he used one of his numerous stolen quirks. The ability, dubbed 'electric sight' allowed him to see through any sort of lens or screen so long as he had access, or could hack, into the network. It was invaluable for intel gathering even if UA's security was constantly updating faster than he could circumvent it for now.
At the moment, he was watching through a security camera as he saw one of his precious sons. The boy used his power to make a Hero capable of doing the one thing they were supposed to be able to.
But All Might had seen his Izuku do it. Had heard him mention being able to take and give quirks. Not to mention Izuku resembled him oh so much ever since the 'awakening' he'd had the good Doctor put his sons through.
"Yes, All Might." All For One urged the universe to side with him, to have that blond oaf drive the last of his sons to 'villainy', "Do what you're thinking!" of his sons, Izuku was the only one who had resisted the 'call' to the family business but also the one who he had the highest hopes for.
Tomura had become his by blood thanks to a few quirks to 'adopt' him. The boy was devoted completely but was immature at best. Lashing out without any semblance of control.
His other sons were all fascinating people to watch remotely. They'd been an experiment of his, donating his seed to several sperm banks to see if he could spawn powerful quirks to collect later, or even more 'villains' society would drive into his arms.
His eldest son Yoshio, or 'Nine' as he preferred to be called, had a phenomenally powerful weather manipulation quirk. One that unfortunately came with advanced cellular decay. He'd seen Nine developing a 'might makes right' philosophy about quirks early on so it had been child's play to ensure he came across a copy of Destro's autobiography. Now his eldest strove for a world where only the strongest quirks existed.
Then there was his second son, Kai Chisaki. He'd lost the boy after the boy's mother had died and he'd run from the orphanage that night. He'd searched to find the boy and take him in, but another found his son first. A Yakuza Boss had taken in and adopted Kai, something that piked All for One's curiosity. He'd watched Kai be raised under the principles of the old Yakuza. Saw him rapidly rise through the ranks of the Yakuza thanks to both his genius level intellect and his quirk 'Overhaul', the ability to reshape matter with a touch so long as he understood what it was made of, and didn't lose his hands. Unfortunately, the intimate studying of organisms had led to an extreme mysophobia and there were even budding signs of distaste towards quirks in general.
And then there was his youngest, Izuku. A genius level analyst towards quirks, both how to use them and how to improve them. Paired with a quirk referred to as 'Nature's Gift'. A powerful ability that allowed his son to control the facets of the planet itself. Izuku could control earth, water, and even plants. The downside to this quirk was that he was extremely susceptible to toxins or pollutants. He was inextricably tied with nature itself. He was also the only one who'd yet to 'fall to villainy' as society liked to say.
Those three boys had been the only children of his donated seed to even develop quirks, and all three possessed Class Ten aberrant abilities. The Good doctor had been thrilled at the data to study, about how his progeny would either have their quirk factor consumed by his part of their DNA or would develop the highest tier of quirks. The Doctor had been tasked to slip into their primary hospitals, implanting them with a bit of All for One's own quirk factor and, much like he'd hoped, they'd developed a copy of his own quirk. Albeit a limited one.
"Yes, All Might." All For One hissed, his eyes would have blazed with eager madness if he'd still had them, "Drive my son into my waiting arms!" with the might of his four sons, he would be unstoppable. He just needed to collect the boys, for society to drive them into his arms.
-Nezu-
"Well, this is a surprise." Nezu tried to hide his nervousness as he stirred his tea. All Might had gathered everyone who knew about One for All. That could only mean he'd decided upon a successor or there was news about the thought dead All for One. Either way, this meeting was going to be important.
"All For One…has a son." All Might's serious voice made the room freeze.
He was going to need more tea.
AN: Next chapter goes straight to the entrance exam, and I'll have Izuku meet Fuyumi and start showing off Izuku's existing friend circle. Current plans for his best friends going into the school are Ururaka and Kaminari as I've never seen those three be a trio before.
