"Haha, it's nothing now."
XLR8 casually clapped his hands, his tone relaxed.
"Ugh…"
Everyone around them dropped to their knees and started vomiting. Even the Tetramand's face turned a sickly green.
RUMBLE!
The next second—
The Rhinoceros Beast smashed straight through a building, its savage eyes locking onto Ben.
"Ben? No… you're not him… you're not as muscular as him!! Never mind—no matter who you are, I'll kill you!"
"…What? I'm not as muscular as someone else?"
A vein bulged on XLR8's forehead as irritation flashed across his face.
He was being underestimated.
"ROOOAR!!"
The Rhinoceros Beast charged again, thundering straight at XLR8.
"Compared to Vilgax… Kevin… You're still not strong enough!!"
XLR8 stomped the ground and surged forward to meet him.
One body was enormous—slow, brutal, unstoppable.
The other was small—lightning-fast.
At the instant they collided—
WHOOSH!!
XLR8 leaped high into the air, flipping cleanly over the Rhinoceros Beast.
His powerful tail whipped down with pinpoint precision—
SMACK!
Straight into both eyeballs.
"AAARGH!!"
The Rhinoceros Beast howled in agony and crashed heavily onto the ground.
BANG! BANG! BANG!
XLR8 accelerated wildly, afterimages covering the Beast's entire body as his claws tore into its mechanical armor.
Cracks spread rapidly across its shell.
"S-So… So strong!!" Future Gwen stared in shock, eyes wide.
Ethen nodded in satisfaction.
"In a few minutes, Ben will be able to handle this idiot on his own."
Ben's growth was obvious.
"ROOOAR!!"
Bleeding from its eyes, the Rhinoceros Beast forced itself upright.
It dropped to all fours and went berserk, charging straight through the street.
BOOM! BOOM! BOOM!
Buildings collapsed one after another, debris raining down like a storm.
XLR8 chased after it, dodging rubble, but the chaos slowed him down.
At that moment—
DING! Mission Issued: Maximum Security Inmate — Rhinoceros Beast at the End of Its Rope
Objective: The Rhinoceros Beast is no match for Ben Tennyson and is attempting to flee, causing massive casualties and economic damage. Eliminate it.
Reward: 20 Points
Tch.
Trash.
Ethen curled his lip.
Future Gwen suddenly turned to him.
"Earlier… what did you mean by 'getting the unpleasant part out of the way'?"
"Now," Ethen said calmly, "I'll show you."
He raised the Omnitrix, tapped the Master Control, and rotated to his favorite alien.
WHOOSH!!
An green flash erupted.
A massive figure burst out—
CANNONBOLT!
But this Cannonbolt was different.
He wore a sumo-style outfit, layers of thick fat wrapped over bulging muscles, his presence overwhelmingly violent.
"Huh?" Future Gwen blinked. "Your Omnitrix has a one-click costume change too?"
For a second, she thought it was some dress-up feature.
RUMBLE!!
Cannonbolt curled into a ball and rolled forward like a living cannonball.
He blasted past XLR8, crushing debris beneath him as he closed in.
"Another… transformer?!"
The Rhinoceros Beast turned its head, expression twisting in alarm.
They collided head-on—
BOOOOM!!!
The Rhinoceros Beast was blasted backward and slammed into the street.
Cannonbolt uncurled and stood tall.
"You've exposed your weakness."
The Rhinoceros Beast roared and thrust its horn toward Cannonbolt's chest.
Everyone knew Cannonbolt's fighting style.
Rolling.
More rolling.
And even more damn rolling.
When he stopped rolling, he was usually bottom-tier.
"…You want to wrestle me?" Cannonbolt's stance shifted.
Something ancient stirred in his DNA.
He dropped into a sumo stance.
BANG!!
Both hands shot out and grabbed the horn.
It stopped dead.
No matter how hard the Rhinoceros Beast pulled, it couldn't move even an inch.
Its bloodshot eyes trembled.
Cannonbolt's muscles bulged, golden eyes blazing with dominance.
With a deep roar, he lifted—
And executed a brutal sumo throw, smashing the Rhinoceros Beast into the ground.
RUMBLE!!
Armor shattered.
The Beast lay there, unable to move.
"T-Too strong…"
He stared at Cannonbolt in terror.
This Cannonbolt… was monstrous.
He even knew sumo wrestling.
"Continue—"
Cannonbolt grabbed the horn again, preparing to lift him.
"WAIT! WAIT!!" The Rhinoceros Beast screamed.
"I surrender! Send me back to the Maximum Security Prison!"
A sly glint flashed in his eyes.
This had worked before.
Prison.
Escape.
Repeat.
"It surrendered…" Future Gwen flew over, relieved.
"We can take it back to the Plumbers."
XLR8's expression turned strange.
Now he understood what Ethen meant.
"Surrender?" Cannonbolt froze.
Then—
RUMBLE!!
His fist slammed down.
CRACK!!
The Rhinoceros Beast's forehead shattered, blood spraying everywhere.
"PLUMBER—WHAT ARE YOU DOING?!"
"You violated regulations! This is lynching!"
"I'LL SUE YOU!!"
"I am the Plumbers." Cannonbolt replied coldly.
RUMBLE! RUMBLE!
Punch after punch smashed down.
Skull crushed.
Silence.
The Beast collapsed, dead.
No movement.
The street went quiet.
Gwen and XLR8 stared, stunned.
This wasn't Ethen's usual clean execution.
This was pure violence.
Future Gwen's pupils shook.
Her worldview shattered.
Cannonbolt slowly pulled back his blood-covered fist.
"This is my answer. I'll help you deal with Maximum Security Inmates—permanently. No mercy. No prisons. Only extermination."
This wasn't his universe.
This world had already rotted for decades.
And he wouldn't be coming back.
So why let the scum live?
