"ROAR!!"
Humungousaur unleashed a thunderous roar that shook the entire supermarket, revealing his towering, muscular figure.
Standing nearly three meters tall, his body was a fortress of strength — brown-green scales layered like natural armor, every muscle bulging with raw power. He looked like a humanoid dinosaur — the kind that ruled the food chain.
"It's a Vaxasaurian! And not just any one — that's the strongest I've ever seen!" Grandpa Max exclaimed, eyes wide.
The Omnitrix's DNA is always perfectly optimized, and Ethen's transformation was no exception.
"Ben, I'm here."
Humungousaur lowered his head slightly to avoid the ceiling and stepped out from behind the shelves, his heavy footsteps shaking the ground. His glowing green eyes locked onto the three mutated creatures attacking Ben.
Then, without hesitation, he turned his gaze to Dr. Animo.
"What the— another giant?!"
Dr. Animo's heart skipped a beat. That monstrous figure, that calm, terrifying stare — the pressure was suffocating!
"Bullfrog! Hamster! Lizard! Attack him together! Take down that dinosaur!" Animo shouted in panic.
The giant frilled lizard was the first to lunge forward, hissing and charging.
Humungousaur stopped in place. His stance shifted, his massive fists tightening.
For years, Ben's Humungousaur had been mocked as "Defeated Saurian" — all power, no technique. But Ethen's version wasn't the same.
He'd trained. He knew how to fight.
Crack—!
The air trembled as he drew back his fist, his body coiling with power. When the frilled lizard came within reach—
BOOM!!
The punch shattered the sound barrier. The frilled lizard froze mid-leap as Humungousaur's fist slammed into its face, launching it through the far wall like a meteor!
A long streak of blood trailed behind it before it disappeared into the rubble.
"One… one punch?"
"No way!"
Dr. Animo's eyes bulged. "He—he must've used all his strength! That's impossible otherwise!"
"Even with four arms, I couldn't win that fast," Four Arms muttered, stunned.
"Boxing stance, controlled power… Ethen's clearly trained in hand-to-hand combat,"
Grandpa Max said, astonished at how skilled the so-called "Plumber trainee" really was.
The giant hamster screeched and lunged.
Humungousaur's tail suddenly whipped out like a steel bat— THWACK! —slamming the hamster right between the eyes. It dropped instantly, fainting on the spot.
Then came the giant turtle. It stretched its neck to bite, but Humungousaur grabbed it by the shell and threw it over his shoulder in a perfect wrestling move.
The ground cracked as the turtle slammed down, its legs twitching helplessly.
The entire supermarket fell silent.
He hadn't even used full power — just basic strikes. Efficient. Lethal. Overwhelming.
"A monster… that fights like a human martial artist?"
"He just used boxing, wrestling, and tail techniques!"
"He's insane! Alien bro's a total beast!"
The crowd erupted in cheers, their blood pumping with excitement.
"Phew~ The nickname 'Defeated Saurian' ends today," Humungousaur said with a confident grin.
"From now on— it's One-Punch Saurian!"
He turned to Four Arms, who was still in awe.
"Ethen— I mean, Super God Humungousaur— teach me those moves! That was awesome!"
Humungousaur frowned. "Super God? No. Just call me Humungousaur."
Then his expression hardened as he turned toward Dr. Animo and began walking forward.
Animo's breathing grew ragged. "No… stay away!"
He frantically activated his Gene Splicer, mutating every nearby animal in sight. Birds, lizards, and rodents twisted into hideous monsters and charged.
But Humungousaur didn't flinch. Every punch was decisive — one hit per creature, each one dropping instantly.
Seeing his creations fall like paper dolls, Animo panicked. He leapt onto a giant parrot and flew out of the shattered roof, terrified beyond words.
"Mission complete," the System chimed in Ethen's mind.
"Reward: 10 points."
Humungousaur sighed. "Too bad he got away."
Then he grinned. "Oh well. Maybe he'll come back with something stronger next time. I could use better missions."
Ben and Four Arms regrouped near the ruined aisles. "Everything's fine now!" Four Arms scratched his head. "Uh… sorry for breaking half the store."
Instead of anger, the crowd clapped and cheered for them.
Soon after, the four heroes regrouped in the Rustbucket.
"Ethen, I think we should investigate that scientist," Gwen said, typing on her laptop.
"Here — Dr. Aloysius Animo. Former biologist, repeatedly rejected for the Truth Prize. His entry this year? The Gene Splicer."
Grandpa Max nodded. "Then we'll head to the Truth Prize ceremony tonight. I bet that's his next move."
Meanwhile, Ben wouldn't stop pestering Ethen — asking for fighting lessons, touching his Ultimatrix, and throwing endless questions his way.
Meanwhile, in a dark alley, the giant parrot crash-landed, exhausted and vomiting from stress.
Dr. Animo tumbled off, gasping, eyes still wide from fear. The image of Humungousaur's massive frame crushing his monsters haunted him.
"The strongest creature on Earth… that thing can't be real…"
Then his face twisted into determination. "No… I'll make something even stronger. If I have to go all out, then so be it!"
He adjusted his goggles, stood up straight, and muttered coldly:
"Humungousaur… next time, I'll be ready."
