The ship was a graveyard of twisted metal and cooling purple blood. Boros, the Dominator of the Universe, lay broken on the floor, his armor shattered and his life force flickering like a candle in a hurricane. His final eye clouded over as he looked at the retreating back of the bald hero. "You were... too strong," Boros wheezed, waiting for the cold embrace of death.
But the darkness didn't come. Instead, a voice that felt like the grinding of tectonic plates echoed inside his soul, vibrating through the very atoms of his failing body.
"DO YOU WISH TO BREAK THE LIMITS OF THE ONE WHO BROKE YOU?"
Boros's spirit surged. "Who... who speaks?"
"I AM GOD. TAKE MY HAND, AND BECOME THE GRAVITY THAT CRUSHES ALL."
A massive, skinless hand, woven from the fabric of the stars, reached through a rift in the collapsing ceiling. As Boros reached out and touched it, his body underwent a violent evolution. His skin turned a deep, shimmering violet, etched with glowing white veins of energy. From his shoulder blades, two new powerful arms erupted, giving him a total of four hands to wield the weight of the heavens. In the center of his chest, where Saitama's final punch had landed, a swirling Singularity formed—a miniature black hole that began to warp the light and air around him.
Saitama, who was walking toward the exit of the ship, stopped. He felt a pressure on his shoulders he had never felt before, a heaviness that made his cape hang like lead. He turned to see Boros standing taller than ever, surrounded by crackling violet lightning.
"Saitama! This world is too fragile for our final bout!" Boros shouted. His voice was no longer a lone cry, but a chorus of a thousand dying suns. He slammed his four hands together, and through absolute gravity manipulation, he folded the space between dimensions. In a heartbeat, the ruins of the ship vanished, and they were standing on Gravon, Boros's ancient, long-forgotten homeworld.
Gravon was a jagged, desolate planet where the gravity was ten thousand times that of Earth. The sky was a swirling vortex of purple nebulae. Saitama landed with a light thud, looking around at the purple dust. "Cool trick," he said, adjusting his glove. "But I'm kind of in a hurry. I think I left the stove on."
"Your journey ends here!" Boros roared. He charged, his four hands delivering a barrage of blows that didn't just hit Saitama, but distorted the vacuum of space around him. Each punch carried the weight of a moon. As he fought, Boros activated his Energy Absorption, creating a localized vacuum designed to suck the kinetic force and life from Saitama's body.
Boros grew frantic. No matter how much energy he siphoned, Saitama didn't even look tired. "Why... why can I not empty you?" Boros gasped, his four hands trembling. "Your energy is like a bottomless well!" He felt as though he were trying to drain an infinite ocean with a single cup.
In a fit of divine rage, Boros flew high into the purple atmosphere. The singularity in his chest began to pulse with a terrifying, blinding light that threatened to swallow the entire star system.
"If I cannot drain you, I will recreate the beginning of all things! GRAVONIC BIG BANG!"
The singularity expanded, pulling in the rocks, the air, and the very light of the planet. He was about to release a blast that would reset reality itself.
Saitama didn't wait. He stepped into the air, leaping off the sheer pressure of the atmosphere. "Serious Series: Serious Punch!" His fist slammed directly into the swirling singularity in Boros's chest. The impact didn't cause an explosion; instead, it caused a leak. Millions of glowing cosmic particles sprayed out like diamond dust. Boros scrambled, using his four hands to desperately pull the particles back into his chest, but in the chaos, a dense nugget of that raw cosmic energy flew into Saitama's open mouth.
Saitama swallowed it by accident.
"You fool!" Boros gasped, clutching his leaking chest. "That was the seed of a new reality! It will collapse your internal organs into a point of zero volume!"
Saitama stood perfectly still on the jagged surface of Gravon. His face went pale, and he clutched his stomach.
"Oh no..." Saitama groaned.
"Yes! Feel the collapse of your existence!" Boros cried out.
"It's... it's a rumbly in my tumbly," Saitama said, his voice echoing. "That thing is sitting heavy. I think... I think I'm really hungry now. It feels like I swallowed a bowling ball made of lead."
Boros lost all reason. He reached out his four arms, his fingers clawing at the void, and gripped a Massive Star—a sun so gargantuan it was larger than an entire galaxy. With his ultimate gravity, he hurled the flaming giant at the planet. "THEN PERISH UNDER THE WEIGHT OF THE SUN!"
Saitama looked up. The wall of fire was so large it blocked out every other star in the sky. As the heat began to singe his suit, the singularity in his stomach started to vibrate against his diaphragm. It tickled with an intense, cosmic itch.
"Ah... ah... ACHOOO!!"
Because the singularity was trapped inside his digestive system, the sneeze was unlike anything the universe had ever seen. A blinding, rainbow-colored beam of pure energy erupted from Saitama's mouth. The beam hit the galaxy-sized star and completely vaporized it into nothingness.
The sheer force of Saitama's sneeze-blast was so immense that it didn't just destroy the star; it shattered the "divine" connection Boros held. With a scream of agony, the violet cosmic energy was ripped away from Boros's body. His two extra arms withered into ash, his skin returned to its scarred, pale state, and the singularity in his chest vanished, leaving him powerless and broken in the dust.
Boros lay there, staring at the empty sky where a galaxy-sized star had just been. He looked at his shaking, two-handed grip. "He took it back... God took it back because I failed," Boros whispered, his voice trembling with despair. "I have no strength. I have no rival. I have no world left. What am I... if I am not the strongest?"
Saitama walked over, the dust of the planet crunching under his boots. He looked down at the fallen king, not with pity, but with a calm, steady gaze. He reached out a hand—not to strike, but to help him up.
"You're wrong, Boros," Saitama said, his voice deep and heroic. "Strength isn't about the power you're given by some voice in your head. It's about the will to keep standing when you've lost everything."
Boros looked up, stunned.
"You spent your whole life looking for a fight to end your boredom," Saitama continued. "But now you've got the hardest fight of all ahead of you. Don't look for a challenge in the stars. Look for one in yourself. If you can't be the strongest warrior anymore, then be the one who rebuilds what was broken. That's a fight that never ends."
Boros stared at Saitama's hand. For the first time, he didn't see an enemy or a wall he couldn't climb. He saw a teacher. He took Saitama's hand and pulled himself up, his eyes focusing on the barren horizon of his home planet.
"A fight... that never ends," Boros repeated, a new kind of fire igniting in his single eye. "To rebuild... instead of destroy."
Saitama nodded and turned toward a fading rift in space. "Yeah. Besides, gardening is way harder than punching things. Good luck with the planet."
As Saitama vanished back to Earth, Boros stood alone on the silent rocks of Gravon. He wasn't a conqueror anymore, and he wasn't a god. He was a survivor with a purpose. He knelt down, pressing his two hands into the purple soil, beginning the long, impossible task of bringing life back to a dead world.
