The moment their bodies collided—
BOOM!!
Four Arms' massive frame slid backward, boots carving deep grooves into the ground, nearly sent flying.
"We won!!!"
Vilgax roared in wild delight, pouring even more force into his right fist.
"That right fist of Vilgax's is insane…"
"Is that the legendary Golden Right Fist?!"
Tetrax Shard, Brainstorm, and the others watched in silence.
Tini clenched her four hands, but the pain wracking her body made even that unbearable.
She could only pray.
Come on… handsome…
WHOOSH!
Four Arms steadied himself.
His four hands snapped shut around Vilgax's right fist, forcibly dragging it toward his own shoulder.
Vilgax seized the opening and smashed another punch straight into Four Arms' shoulder.
BANG!!
Four Arms didn't move.
Not an inch.
His shoulders and chest swelled grotesquely, muscles bulging like coiled steel cables.
"T-This muscle density…?!" Vilgax's eyelids twitched violently as disbelief filled his face.
"As a construction worker, I use my body every single day to bear the weight of life itself. Loads far beyond my limits… All of it—to survive."
Four Arms' eyes burned with rage.
He jerked his shoulder—
And shook Vilgax's arm off him entirely.
Vilgax staggered.
Before he could recover—
BOOM! BOOM! BOOM!!
Jabs.
Straight punches.
Hooks.
Each strike carried refined boxing technique layered with terrifying brute force, hammering Vilgax's weak points again and again.
"PUFF—! COUGH—!"
"It hurts… it hurts so much!!" Bruises spread across Vilgax's body.
Bones fractured.
Teeth flew.
He was reduced to nothing more than a living sandbag.
"If I can overcome life itself— Then you, a fake, undeserving overlord of the Milky Way Galaxy—
MEAN NOTHING!!" Four Arms' fury exploded.
Decades of invisible labor.
Endless bricklaying.
All of it poured into his fists.
BANG!!
Four Arms' four fists struck simultaneously.
Vilgax was blasted away, skidding across the ground.
At that moment—
A figure rushed forward.
"…Uh?"
Four Arms froze as someone threw themselves in front of him.
"Handsome. Accept my proposal!!"
Tini beamed, eyes shining.
Four Arms' face instantly turned red.
"R-Really?" he asked nervously. "Really… madam?"
Don't forget—
Ethen didn't just inherit the memory of bricklaying.
It was pure bricklaying memory.
His aesthetics had been thoroughly destroyed.
At this moment, in his eyes—
Tini was nothing short of a goddess.
"Of course!" Tini said happily.
"After you defeat Vilgax, we'll get married!"
"Then… Alright." Four Arms smiled shyly.
"COUGH—COUGH!!"
Vilgax spat clotted blood as he shakily climbed to his feet, eyes filled with hatred.
"Ah… right." Four Arms scratched his head.
"There's still you. Then let's switch aliens to finish this."
His hand reached the Omnitrix, rotating the symbol.
Since it was Vilgax—
It would be disrespectful not to use one of the original Big Three.
Heatblast.
Four Arms.
That left—
Diamondhead.
CLICK!
Light flashed.
Diamondhead emerged.
He wore a miner's uniform.
A crystallized helmet.
His right arm had permanently transformed into a crystal pickaxe.
"Husband… Why did you switch aliens?" Tini asked, pouting.
"…Uh." Cold sweat poured down Diamondhead's face.
He couldn't even think about what he'd said earlier without wanting to die on the spot.
"If he really marries Tini, we should recruit him into the Galactic Enforcers," Tetrax said excitedly.
"The couple could fight side by side."
Brainstorm wiped imaginary sweat.
"Boss… let's not jump ahead."
Diamondhead clearly wasn't ready for marriage.
Vilgax finally spoke, voice hoarse yet commanding.
"What is your name? Tell me. From this battle onward, your name will stand beside Tennyson. You will be the one who defeated the overlord of the Milky Way Galaxy!!"
Diamondhead sighed.
"How many times do I have to say this? My name isn't Ben Tennyson."
"No—!" Vilgax roared.
"Say your real name!!"
Diamondhead raised his crystal pickaxe and stepped forward.
"Remember it."
"Ethen."
"Okay! Husband Ethen!" Tini shouted.
Diamondhead stumbled, nearly faceplanting.
"Heh… what a happy young couple," Vilgax mocked calmly.
Diamondhead's expression darkened.
The pickaxe swung—
CRACK!!
It pierced Vilgax's right arm.
Diamondhead pressed down.
Pulled.
Vilgax's entire arm dislocated instantly.
BANG! BANG! BANG!!
The crystal pickaxe rose and fell relentlessly.
To Diamondhead—
Vilgax was nothing more than humanoid ore.
After a few minutes—
Vilgax collapsed.
Broken.
Barely breathing.
"DING! Congratulations, Host, for completing the mission!"
"Host has received 30 reward points!"
Diamondhead retracted the blood-stained pickaxe calmly.
"It's over."
"…Gulp." Tetrax watched, unsettled.
"Tini's fiancé is… terrifying."
"Shouldn't he be sent to the Null Void?" Tini asked loudly, confused.
"My rules are the rules."
Diamondhead glanced toward the Plumbers, voice firm.
Brother Ben's timeline was already broken.
But in Ethen's universe—
His strength and will were reshaping everything.
Ten years.
Twenty years.
The future would be completely different.
