The air above Jaku General Hospital crackled with anticipation. Minato, his golden Kyūbi Chakra Mode 1 (KCM1) flaring brightly around him, didn't hesitate. With a surge of incredible speed, he launched himself towards the grotesque, fused form of All For One, a golden blur against the ruined cityscape.
All For One, his new, terrifyingly enhanced body hovering amidst the debris, sneered, a chilling blend of his and Shigaraki's voices. "Come, Yellow Flash! Let's see if your speed matches your arrogance!" He welcomed the close-quarters engagement, confident in the raw power and destructive potential of his new body.
The two titans clashed. In the ensuing hand-to-hand combat, Minato moved with a grace and precision that defied the laws of physics. His KCM1 enhanced speed allowed him to weave through All For One's multifarious attacks – crushing blows from hardened fists, whipping tendrils, sudden bursts of destructive energy – with effortless ease. He was a golden phantom, always a step ahead, delivering precise, powerful strikes. AFO's attacks, though devastating, rarely connected. Each of Minato's punches, imbued with chakra, landed with concussive force, forcing grunts of pain from the fused villain. It was during one of these rapid exchanges, a blur of golden fists and grotesque limbs, that Minato subtly, imperceptibly, slapped a Flying Raijin symbol onto All For One's back, a silent promise of future advantage. Minato clearly held the advantage in close-quarters combat, his movements fluid, his reactions instantaneous.
All Might (watching from below, grimly impressed): "His CQC... it's magnificent! Even against that monstrosity, he moves like pure wind!"
Endeavor (eyes wide, a rare look of awe): "He's not just dodging, he's dancing around him! This isn't a fight, it's a display of absolute mastery!"
Frustrated by Minato's evasiveness and the sting of his chakra-enhanced blows, All For One roared in fury. "Insolent brat!" He abruptly disengaged from the close-quarters exchange, pushing back with a burst of power. His grotesque body contorted, and he began to unleash his long-range Quirks, attempting to bombard Minato with overwhelming force. Massive air cannons tore through the air, piercing blasts of force erupted from his limbs, and corrosive acid spit rained down.
But these attacks were largely useless against Minato. He simply phased through them, or effortlessly dodged, teleporting just out of reach, appearing a mere foot away from where a devastating blast had just ripped through the air. The speed was so absolute, it made the wide-ranging attacks seem slow and predictable.
"This is getting tedious," Minato murmured, his voice carrying even over the destructive chaos. He swiftly formed a colossal, spinning disc of wind energy, a Rasen Shuriken, coalesced in his hand, humming with a deafening roar. Its razor-sharp blades spun with destructive intent. Minato didn't throw it. Instead, in a flash of golden light, he teleported directly to All For One, appearing at point-blank range, the massive Rasen Shuriken already extended.
"What?!" All For One roared, utterly caught off guard, his monstrous face contorted in shock.
Minato slammed the Rasen Shuriken directly into All For One's chest. The impact was cataclysmic. A vortex of wind chakra exploded outwards, tearing through All For One's new body. The very air shrieked, and a blinding cloud of dust and pulverized concrete erupted, swallowing the two figures whole. The force of the blast ripped through the very ground beneath them, sending shockwaves across the ruined hospital complex.
NEWS REPORTER (on TV, voice trembling with excitement): "An enormous explosion! The Yellow Flash used an ultimate attack! The villain has been engulfed! What's happening?!"
Heroes (Jaku Hospital):
Mirko: "Holy hell! Did he just... vaporize him?!"
Present Mic (on comms): "YEAAAH! TAKE THAT, CREEP! BOOOOOOM!"
Eraser Head (grimly): "Don't count him out yet. That power... it's unnatural."
As the dust slowly began to settle, a terrifying sight emerged. Through the dissipating cloud, the outline of All For One slowly became visible. He was battered, his new form heavily damaged, chunks of his body seemingly torn away, muscles exposed and shredded. But even as the heroes watched in horror, the ravaged muscles began fixing themselves, regenerating at an impossible rate, closing the gaping wounds.
Then, the horror truly began. With a guttural roar, All For One's body began to swell grotesquely, growing larger and larger, his skin hardening, his limbs thickening. His features became more monstrous, more primal. In mere seconds, he achieved a colossal size, towering over the ruined hospital. He was now approximately the size of Gigantomachia, an absolute titan of destruction, radiating an oppressive aura of dark power.
"You dare challenge true power, Yellow Flash?!" All For One's voice, now a booming, earth-shaking roar, reverberated across the city. His new, massive form raised both of his monstrous hands, grotesque veins bulging, and from each palm, a sphere of blinding, concentrated light projectile began to form, pulsating with destructive energy. He aimed them directly at Minato, ready to unleash an obliterating volley.
Minato, seeing the immense scale of the attack, remained utterly composed. He brought his two hands together in front of him, his golden KCM1 chakra flaring. Intricate seals began to materialize in the air between his palms, shimmering with ancient power. As All For One unleashed the twin light projectiles, massive and blinding, roaring towards him, the seals pulsed. With a quiet hum, the energy of the light balls began to get sucked into the seals, compressed and absorbed, vanishing from existence. The seals then flickered, and the absorbed energy was transferred to a kunai Minato had strategically placed days ago, miles away on the outskirts of the town, ensuring the energy dispersed harmlessly into an unpopulated area.
NEWS REPORTER: "He's absorbing it! He's just... making the attacks disappear! What IS this man?!"
HEROES (Jaku Hospital):
All Might: "An absorbing Quirk?! No, He's transferring it away! Unbelievable!"
Ryukyu: "He just nullified an attack that could level a city block! This power is on a completely different plane!"
Mirko: "That's it, I'm just going to stare. My brain can't even process what I'm seeing anymore."
Having nullified All For One's ultimate attack, Minato's golden chakra flared once more, intensifying rapidly. The golden cloak surrounding him deepened in hue, and the distinct, nine-tailed fox form of Kyūbi Chakra Mode 2 (KCM2) solidified around him. He became a shimmering, semi-transparent avatar of the Nine-Tails itself, the colossal form easily dwarfing the now Gigantomachia-sized All For One in terms of sheer, overwhelming presence.
All Might's jaw literally dropped, his eyes wide with a mixture of shock and pride. The other heroes present, from Endeavor to Edgeshot to Mirko, all stood with their jaws agape, utterly speechless at the sheer, unimaginable escalation of Minato's power. It was a transformation that transcended Quirks, raw power unlike anything they had ever witnessed.
All For One roared, enraged by Minato's continued display of superior power. But he was too slow, too consumed by his physical mass. Minato moved. With the same effortless grace he had displayed against Gigantomachia just moments before, he closed the distance. His glowing, nine-tailed avatar extended a massive, chakra-infused hand, pressing it against All For One's colossal chest, just as he had done to Gigantomachia. The sheer force of the KCM2 avatar pinned All For One against the ground, his immense size becoming a liability rather than an advantage.
The villain struggled, roaring and thrashing, but it was futile. Minato's KCM2 form delivered a rapid, concussive barrage of punches to All For One's head and body, each strike carrying the destructive power of a miniature Rasengan. The ground cracked and shuddered beneath the titan. In a matter of seconds, the overwhelming, relentless assault, coupled with the pressure of the chakra avatar, proved too much even for All For One's monstrous resilience. The fused villain went limp, his body slumping into the crater, utterly defeated. He was knocked out cold.
Minato then swiftly placed a series of specialized restraining seals across All For One's gargantuan form, ensuring his Quirk regeneration and massive power remained suppressed. The seals glowed brightly, binding the ultimate evil.
All Might, barely able to stand, staggered forward, leaning heavily on Gran Torino. Tears welled in his eyes, not of sadness, but of overwhelming relief and pride. "Thank you, Young Namikaze," he choked out, his voice thick with emotion. "You... you saved us all."
Minato walked over, his KCM2 form dissolving back into his normal hero uniform, though he still felt the hum of residual power. "All Might," he began, looking at his mentor, "what now?"
All Might looked out at the devastated city, then at the unconscious form of his lifelong nemesis. A profound sense of peace settled over him. He faced Minato, a gentle, melancholic smile on his deflated face. "Now, Young Namikaze," he said, his voice carrying the weight of decades of battle, "now it is time for me to retire. My era... it has truly ended. The torch has been passed."
Minato's gaze was solemn, understanding the immense gravity of the statement. "The world will forever remember you, All Might. You will forever be the Symbol of Peace."
All Might simply nodded, a quiet acknowledgment. Sirens wailed in the distance as police and tactical units, now able to safely approach, swarmed the area. They cautiously made their way towards the unconscious form of Tomura Shigaraki, now separate from All For One's influence, and began the process of escorting him away. The greatest villain in history, and his successor, were finally, truly defeated.
