All Might vanished again, a blur of gold and blue that cut through the air — and reappeared right in front of Mirio. His punch came fast, heavy enough to bend steel — but it passed straight through the boy's face like smoke.
Mirio's eyes sharpened. The instant All Might's arm phased through him, Mirio twisted, pivoting with perfect timing. His leg came up in a sharp kick aimed at All Might's chin. The pro hero moved just in time, ducking beneath the blow, but what followed caught him completely off guard.
Mirio's body vanished halfway into the ground — and from that position, he hooked his arm around All Might's forearm and locked it, using his momentum to leverage the hero's strength against him.
At the same moment, thick tentacles shot out from behind.
They coiled around All Might's chest and shoulders like living cables — a dozen in total, reinforced with steel scales, hardened chitin, and seashell-like plates that gleamed under the city lights. Tamaki's Quirk, combined and evolved, wrapped All Might in a vice.
For the first time, the Number One Hero found himself pinned.
He was ready to break free immediately, his muscles tensing — when two blinding flashes of light burst in his peripheral vision.
One yellow. One violet.
His eyes widened. "Oi, oi, oi… young ones — are you trying to kill me?!"
Sweat rolled down his temple. This was still a training test — but the sheer power radiating from both attacks went beyond anything that should've been allowed in an exercise. If these beams hit anyone other than him, they'd be in the hospital for weeks.
"So… they're holding nothing back. They know exactly who they're fighting," he muttered, bracing himself.
Nejire's voice echoed first: "MEGA WAVEEE!"
And then, silent but unmistakable, Mewtwo raised both hands.
Hyper Beam.
Two colossal streams of light tore through the air in less than a second, converging on All Might's restrained figure.
Mirio released the arm lock a fraction of an instant before impact, phasing through the ground to escape. Tamaki grit his teeth, his tentacles tightening until they snapped from the pressure.
The beams collided with All Might square in the chest.
For a moment, everything vanished inside a sphere of white fire. The explosion expanded outward, forming a perfect bubble of energy that warped the air around it. The pavement melted. Windows shattered for entire blocks. The shockwave sent Mirio flying backward as he surfaced, tumbling across the street.
Nejire and Mewtwo held their ground, their attacks pouring power until both beams finally died down.
When the light faded, silence hung in the air.
All Might stood in the center of the destruction, smoke rising from his body. His suit was torn apart — the iconic blue fabric scorched black and shredded. Blood trickled from his arms and down his chest. Every teacher watching from the control room went still.
No one spoke.
Then All Might exhaled, rolling his neck with a loud crack.
His grin was still there.
"That… was quite the hit," he said with a hoarse chuckle. "You've all come far. But—"
He took a step forward. The ground quivered beneath his boot.
"—I didn't become the Number One Hero just for show!"
In an instant, he was moving again.
Before Mewtwo could react, Mirio burst from the ground beneath All Might's feet, his fist connecting cleanly with the hero's chin. The impact made All Might stagger back — and Tamaki appeared right after, his arm morphed into a massive construct of flesh, scales, and bone. He swung with his full weight, striking All Might's back and forcing him forward.
All Might laughed even as he stumbled. "Incredible! Young ones — you're amazing! I can rest easy knowing the future is bright!"
Then his tone shifted.
"But…"
He flexed his hands, the air trembling around him.
"I may have underestimated you."
He smiled — wide, fearless, and full of power.
"So brace yourselves, my students… I'm leveling up this fight."
The wind grew heavier. Dust swirled like a storm.
And for the first time since the battle began, even the four prodigies felt it — the raw, suffocating presence of a hero fighting seriously.
They steadied themselves, no fear in their eyes — only focus.
The next phase was about to begin.
All Might disappeared again — but this time, even Mewtwo's eyes struggled to keep up. His telekinesis registered motion, but it was everywhere at once.
He'd already used Agility twice, and even with his body pushed to its limit, he couldn't close the gap.
All Might reappeared in front of Tamaki.
The punch landed before the boy could react. Instinctively, Tamaki morphed his arms into a defensive shell of bone, chitin, and muscle — but even that only softened the blow. The impact sent him flying through the air like a cannonball, crashing into the side of a building.
"Tamaki!" Nejire shouted, darting forward — but All Might was already moving again.
Before anyone could intervene, the pro hero appeared beside the wreckage, his hand already pulling Tamaki's limp form out of the debris. One hit more — gentle by All Might's standards — and the boy was out cold.
By the time the others arrived, the Number One Hero was standing calmly in the street, Tamaki slung unconscious over his shoulder.
"Another down," he said, placing the student safely on the sidewalk before vanishing again.
He reappeared directly in front of Mewtwo.
The psychic's eyes widened — barely enough time to react. His barrier flared to life just as All Might's fist connected.
Crack!
The barrier shattered like glass. The shockwave sent Mewtwo flying backward, tearing through the air before he could stabilize himself.
He caught his breath mid-flight, spreading his hands. Life Dew. A soft blue glow washed over him, mending the bruises and burns from the blow. He steadied himself and turned, eyes glowing with psychic focus.
But when he looked again — the fight had already moved.
Far away, down the line of broken buildings, another explosion echoed.
He bolted toward the sound — flying as fast as his telekinesis could push him — only for something to streak past his side.
Nejire.
She was spinning uncontrollably, unconscious, her energy flickering out like a dying flame.
"Nejire!"
He froze his flight just long enough to catch her midair with telekinesis, easing her to the ground before she hit the pavement. She was alive — just knocked out.
He wanted to heal her — he should — but there wasn't time.
Because in the distance, the sky was still falling.
Building after building crumbled like sandcastles under a storm. Dust rose high into the air, and the sound of heavy blows — rhythmic, relentless — thundered from the heart of the chaos.
Mewtwo's eyes glowed brighter.
He shot forward.
When he arrived, he saw Mirio — battered, sweating, eyes sharp — weaving through All Might's attacks. Each punch from the pro hero shattered the air itself, and yet Mirio phased through them all, dodging at the very last instant.
But Mewtwo could tell. His movements were slowing. The rhythm of his phasing faltered, barely noticeable, but clear enough for someone watching with telekinetic sense.
He was reaching his limit.
Mewtwo clenched his fists. "This is a test… but at this rate, it could really kill someone."
He raised his hand, his psychic aura flaring like violet fire. "I didn't want to use this here—"
His voice deepened, echoing telepathically.
"Disable."
The command pulsed out in waves, aimed directly at All Might.
If the hero's Quirk paused even for a heartbeat, that was all Mewtwo needed.
But nothing happened.
All Might didn't slow. Didn't hesitate. His punches kept coming at the same blinding speed, each one shaking the street.
"So… his power isn't something he activates," Mewtwo thought, frustration flashing across his face. "It's constant. His base state itself is his Quirk."
He barely had time to process it before All Might's next blow landed.
Mirio didn't phase in time.
The fist connected squarely with his face, the impact echoing like a cannon blast. Mirio hit the ground, bounced once, and slid across the cracked street — unmoving.
Mewtwo's heart sank.
All Might stood tall amid the dust, his shadow long under the afternoon sun.
"Now it's just you left, shounen," he said, turning his grin toward Mewtwo. "Tell me something—"
He pointed a thumb at the four fallen students behind him.
"I've never seen a team so coordinated. You fought like veterans, like people who've been through years of battle together. It makes me curious…"
He leaned forward, smile fierce.
"You're the one leading them, aren't you?"
Mewtwo's answer was wordless.
A single pulse of power.
A shadow ball, faster than a bullet, shot straight toward All Might's face.
Seeing the dark sphere fly toward him, All Might raised his forearm and deflected it with a sharp thud.
"Young one," he said with a grin, "that was rather impolite!"
But before he could lower his guard, another shadow ball shot forward — faster, heavier. He raised his arm again to block, yet this time a different sensation hit him: a jolt of invisible pressure slammed into his head, like being struck by a giant hammer.
"Psyshock," he realized a heartbeat too late.
His vision blurred, a pulse of confusion clouding his thoughts as another psychic wave followed immediately after. The world tilted for a moment, the edges of his vision rippling. Still, he smiled, shaking it off.
"Impressive… but not enough!"
All Might twisted his legs and vanished, crossing the distance in a blink. He reappeared in front of Mewtwo, fist drawn back.
But Mewtwo was ready.
He couldn't see All Might's movements, but he could feel them — a sudden distortion in the air. Instinctively, he twisted sideways midair, energy swirling between his hands. At point-blank range, a shadow ball formed, glowing with deep violet light.
He launched it straight at the hero's chest.
All Might caught it.
For a split second, he actually held the attack in his palm, his fingers digging into the energy sphere — then hurled it upward, where it exploded harmlessly in the sky.
Before Mewtwo could react, All Might moved again — but this time, the psychic switched tactics.
He brought his hands to his sides, then opened his mouth.
A column of fire burst forth, roaring across the battlefield. The flames struck All Might square in the face, forcing him to step back as the heat seared the air.
All Might raised an arm, wiping soot from his cheek, and let out a low laugh. "Incredible… just how does your Quirk work? It's like you have several at once."
For a brief moment, his expression changed. There was something else behind his grin — something sharp, a hint of the pressure he once unleashed in real battle. The same killing intent that once shook villains to their core.
For the first time, Mewtwo felt a chill of fear.
Instinctively, he layered defenses — Reflect, Barrier, and a charged Thunderbolt held in reserve. His entire body glowed faintly as he floated backward, putting distance between them.
All Might noticed immediately and exhaled. His tone softened.
"Ah, sorry about that. I didn't mean to scare you. You just… reminded me of someone. A villain I fought years ago — he also had multiple Quirks."
At that, a voice echoed directly in his mind.
"Mine is one Quirk. Psychic energy. I manipulate it into different forms and effects, but it all comes from the same source. I only have one."
All Might's eyes widened slightly. Then, he smiled.
"So that's how you coordinated your team — telepathy. No wonder your attacks were so synchronized."
The next moment, he was gone again.
He reappeared above Mewtwo, faster than before, faster than even Mewtwo's mind could track. The air cracked with the force of his movement.
The punch landed clean.
It tore through the psychic barrier like paper and connected squarely with Mewtwo's face, sending him crashing through three buildings before embedding him deep into the rubble.
When the dust finally settled, Mewtwo lay unconscious amid the wreckage.
All Might stood alone in the middle of the simulated city, the wind whistling through the broken glass around him. He looked down at his own body — his suit torn, bruises darkening his arms, smoke rising from his shoulders.
"Fiuuu…" he exhaled, rubbing his neck. "Director Nezu, you didn't tell me I'd be fighting monsters! What are kids these days eating?"
From the observation room, Nezu's laughter echoed through the speaker. "Hahaha! Quite the surprise, wasn't it? So, what's your verdict?"
All Might chuckled, glancing at the ruined skyline.
"The fourth-years are strong — stronger than most pros, I'd say. But those second-years… they're something else entirely. Their coordination, their raw power… they left me looking like this."
He gestured to his battered state, and Nezu laughed even louder.
"Hahaha! Just as I expected! Then it's settled," Nezu said, his tone brimming with pride. "From this day on — given how they crushed every expectation and redefined what it means to face overwhelming odds…"
His voice carried through every speaker in the arena.
"They shall be known as—"
A pause. A smile.
"The Yonkous!"
