One-Punch Man: Boros, the Universe Overlord

"Damn it... In just a moment, in just a moment, they defeated all those elite modified creatures, the Beast King, to whom I poured countless efforts!"

In the dimly lit center of the laboratory, Dr. Genus stared intently at the monitor screen, his fingers white from gripping it too tightly. Sweat streamed down his forehead as he growled through gritted teeth, "There's no other way... You forced me into this! Face the ultimate weapon of biological evolution!"

Meanwhile, in the deepest, most confined space of the base, a heavy alloy gate slowly opened, releasing a suffocating sense of oppression. A colossal object slowly emerged.

"Heh, I told you long ago," the figure let out a chilling laugh, its voice filled with arrogance and contempt, "Defective products like Beast Kings are useless. So-called 'perfect evolution' has never been achieved by simply piling up numbers."

The creature stepped out. It was a colossal monster with features vaguely resembling a human, yet possessing a terrifying, insect-like physique. Its muscles bulged beneath its carapace like coiled dragons, brimming with explosive power.

"Do you understand now, Genus?" The Asura Rhinoceros Beetle slowly stretched out its massive limbs, its scarlet compound eyes flashing with bloodlust, looking down at the tiny doctor before it, and declared, "In this world, I am the only perfect new human. I am the pinnacle of evolution!"

At this moment, a dull tremor suddenly came from the ground, and footsteps slowly sounded in the distance. The Asura Rhinoceros Beetle was not alarmed at all. Instead, it turned its head, and its carapace-covered face grinned exaggeratedly, revealing a hint of excitement. It stuck out its long tongue and greedily licked its lips repeatedly.

"Oh, oh... they've found us!" The Asura Rhinoceros Beetle lowered its upper body, its muscles rippling like waves beneath its carapace, emitting a low, thunderous roar, its huge eyes flashing with cruel killing intent.

当几道身影出现在视野尽头时，他那非人的瞳孔开始像清点猎物一般上下打量，「1、2、3、4、5……嗯？蚊女和那个负责做饭的装甲大猩猩竟然还活着？背叛了吗？竟然有胆量出现在我面前？」

His gaze swept over the group, his tone filled with brutality: "Ginos, which blood sample do you want? The rest of you, tear them all to shreds and make mincemeat. You shouldn't have any objections, right? Hahaha!"

Under the gaze of the Asura Rhinoceros Beetle, the Mosquito Girl trembled and hid in the corner, even folding her wings, while the Gorilla simply collapsed to the ground.

Just then, Genos stepped forward, blocking the crowd's path and staring directly at the colossal creature before him. His voice was calm: "You're the strongest monster they speak of? Then I—Genos—will personally destroy you!" With that, he charged towards the Asura Rhinoceros Beetle…

With a series of crackling and crashing sounds, after a dazzling display of special effects, Genos, who had been utterly ravaged, was sent flying back at incredible speed. He knelt before Boros, clutching his mangled metal body and coughing up blood, saying, "I'm sorry, Boros-sensei, I was careless..."

Trying to save face...

"Is this all the intruders are capable of?" Ashura the Rhinoceros Beetle, now even more arrogant after defeating Genos, beckoned to Boros and Saitama with a finger, taunting, "Come on, aren't you scared out of your wits? Who's going first? Or... are you going to attack together? Hahahaha!"

Dr. Genus, standing beside him, gleamed with fanaticism. He screamed hysterically, "Do you see that? This is the most powerful demon in history, created by the House of Evolution with everything they've poured their hearts and souls into it—the Asura Rhinoceros Beetle! Faced with the ultimate product of artificial evolution, how will you deal with this monster that surpasses all limits? Will your cells, your combat data, become the trigger for my next evolutionary experiment? Let me see clearly!"

"Huh? Who are you?" Saitama asked, looking completely bewildered.

"That's Dr. Genus, the founder of the House of Evolution." Boros suppressed a smile, looking at Genus's shocked expression of "Are you kidding me?", and casually explained to Saitama, "He's a freakish scientist."

"Oh, is that so? Boros, let's finish this quickly and call it a day. I'm a little hungry. Let's hurry back and see what delicious food King made today."

"Saitama, aren't you going to do something? Aren't you even a little bit interested in this nobody?"

"Well, never mind, it's just so-so. I don't see any difference between it and other weirdos."

Seeing the two of them standing there oblivious to him, ignoring him and even chatting about dinner, the Asura Rhinoceros Beetle's huge eyes instantly became bloodshot.

"You two pathetic little bugs! Are you so terrified you've started spouting nonsense?" The Asura Rhinoceros Beetle roared deafeningly, the alloy floor beneath his feet cracking instantly. He swiftly raised his muscular fist, locked onto Boros, and launched himself forward like a cannonball.

"Since you don't dare to come up, then I'll personally send you to hell! I'll start with you, you arrogant pineapple head, and watch me punch you into a meat patty!"

"Pineapple...head?"

Boros, who had been expressionless, froze instantly, his face filled with utter disbelief.

"How dare you... call me Pineapple Head?"

These words seemed to be squeezed out from between his teeth. Boros's previously restrained aura instantly changed, and a massive, overwhelming killing intent solidified like a black storm, sweeping up.

The Asura Rhinoceros Beetle, which originally intended to kill Boros with a single punch, suddenly stopped in mid-air in the face of this terrifying killing intent. Not only did its charge come to an abrupt halt, but it also slid back to its original position in a sorry state at a speed even faster than when it charged forward, its hard carapace plowing two deep furrows into the floor with its feet.

The Asura Rhinoceros Beetle's massive body trembled violently, cold sweat soaking his entire body like rain. His eyes widened in terror, the savagery gone, replaced by the instinctive fear of facing an absolute natural enemy.

"I'll die... I would definitely die if I had attacked just now!" Ashura Rhinoceros Beetle's mind collapsed at this moment, and fear overwhelmed him like a tidal wave.

"This guy... for a split second just now, I felt like every cell in my body was screaming, trembling, and desperately trying to escape! Like a human facing a tiger, damn it... this is something I can't possibly contend with in my normal state!"

This fear drove him almost mad, his survival instinct instantly transforming into rage against the weak. He abruptly turned his head, his bloodshot eyes fixed on Saitama, who stood to the side, seemingly harmless, a twisted sense of relief rising within him:

"This seemingly weak bald guy is easy to deal with! Let's tear this troublesome little fish to shreds to vent our anger first, then figure out a way to escape..."

With this twisted logic, the Asura Rhinoceros Beetle let out a fierce but cowardly roar, turned around, and charged madly toward Saitama, swinging its huge fist.

Feeling the whistling wind of the punch, the bald demon king instantly switched to a fighting expression, his eyes turning slightly more serious as he glanced coldly backward. The scene repeated itself, and the Asura Rhinoceros Beetle was once again sent flying back to its original position at lightning speed.

"Twice, twice in a row, the Asura Rhinoceros Beetle retreated?" Dr. Genus exclaimed in shock.

"Hey, what are you doing flying around like that? Is it some kind of acrobatic act?" Saitama asked calmly.

"Baka...Baka!" Ashura Rhinoceros Beetle's rational defenses finally collapsed completely. His eyes were bloodshot, drool dripped from the corner of his mouth, and he let out a beast-like growl.

"Who are you two bastards? How do you possess such immense power?"

"Impossible! It must be an illusion. I am the pinnacle of the new humans... the most perfect evolver. How could I be intimidated by two nobodies like you? What tricks have you played?"

Asura Rhinoceros Beetle screamed in despair, and before Boros and the other could reply, he roared angrily again!

"I don't care what tricks you play... it doesn't matter at all! How dare you toy with me like this, drink up!!!"

He suddenly spread his arms wide, his muscles bulging wildly, even tearing his skin, and an eerie blue light began to shine through the gaps in his carapace.

"Just you wait! Pineapple head! And that bald guy over there!" The Asura Rhinoceros Beetle roared fiercely, its voice shaking the entire underground base.

"This is my true power! In this mode, I won't be able to regain my sanity for the next week! Ash—"

"...Pineapple head?"

"...A bald guy?"

Before he could finish shouting, Saitama and Boros turned around at the same time, both of them expressionless, with only a cold and deathly aura emanating from them.

A strange sense of suffocation suddenly filled the entire space...

"Unforgivable."

Saitama slowly clenched his fist, his knuckles cracking as he calmly spoke.

"Unforgivable."

Boros's single, crimson eye burned with rage, the ground beneath his feet crumbling into dust as he roared furiously.

"Collapsing Star..."

"serious……"

The sounds rang out almost simultaneously, followed by two figures transforming into streaks of light and rushing straight towards the Asura Rhinoceros Beetle, which was still transforming.

"Roaring Cannon!!"

"One punch."

Angry roars and earnest whispers overlapped at that moment, and destruction and end came simultaneously.

Two world-destroying forces surged toward the Asura Rhinoceros Beetle almost instantly!

An indescribable force tore through space, followed by an explosion of blazing white energy ten thousand times more dazzling than the core of the sun. The surrounding space visibly collapsed, and all instruments capable of observing this area exploded within that millisecond.

The terrifying power unleashed energy that erupted wildly in all directions. Endless white light, like liquid death, spread outwards at the speed of light, instantly vaporizing hard alloy walls and thick rock layers wherever it passed. The energy torrent that annihilated everything relentlessly slammed against the planet's surface.

The once hidden underground depths were blasted into a huge sinkhole that led straight to the surface. The violent shockwave crushed everything in its path—mountains, buildings, and even the atmosphere—into the most primitive particles.

For a very long time...

The blinding white light, capable of engulfing everything, finally subsided slowly, dissipating into the air like the receding tide. The lingering smoke was gradually dispersed by the violent aftershocks.

The once-hidden underground base, along with the mountain above it, has long since vanished, replaced by a massive sinkhole several kilometers in diameter and seemingly bottomless. The rocks at the bottom of the sinkhole melted and cooled under the high temperature, forming a smooth and jagged obsidian-like crystalline surface, with wisps of smoke still rising from its edges.

Amidst this ruin resembling the surface of the moon, a few surviving figures stood bewildered. Dr. Genus, ragged and with his glasses long gone, stood blankly at the edge of the crater, his once fervent and confident eyes now empty and lifeless. He stared at the corner of the map that had been forcibly erased from his face, his mouth agape, a dry, gurgling sound escaping his throat, unable to speak for a long time.

After a long while, a cold wind blew by, and his legs went weak, causing him to collapse to the ground, muttering to himself:

"Wh...what...what is this? How can such power exist? Is there any point in my experiment...?"
