Kevin—
He had actually transformed into Vilgax.
Four Arms stared at him, his expression changing drastically as shock filled his voice.
"Kevin… Vilgax… he gave you his DNA?!"
Bang!!
Kevin suddenly raised his fist and smashed his clawed backhand straight into Four Arms' chest, forcing him backward!
He sneered softly.
"That's right. To increase my chances of defeating you, Vilgax bestowed his DNA on me. Giving me extraordinary power."
"Ben Tennyson—you're dead."
Alien heroes.
Ten alien transformations.
All of it was inferior to Vilgax's perfected DNA.
Note: The DNA Kevin obtained wasn't merely Vilgaxian race DNA. It was Vilgax's own DNA, refined through countless breakthroughs and honed to its absolute peak.
Whoosh! Bang!!
High above the battlefield, a meteor streaked back and forth across the sky.
Because of the distance—
Neither Ben nor Kevin noticed the anomaly overhead.
Alien X hovered silently, his expression unusually tense, his hyperactivity barely restrained.
"Kevin's aura suddenly became terrifying…"
"It's already close to Vilgax's normal combat state."
At present, Kevin's strength was still slightly inferior to Vilgax—
But it had already reached the 50–60 reward point level.
At the same time—
Ben Tennyson had worn the Omnitrix for a full month now.
His growth was just as astonishing.
It was genuinely hard to say who would win.
"Hmph… Vilgax! I'll go all out!!"
"Four Arms—Bullet Punch!"
Four Arms roared as all four fists moved at once, unleashing a terrifying Bullet Punch!
Bang! Bang! Bang!!
Kevin couldn't even see the fists.
The moment he raised his arm, he was blasted backward head-on!
How was that possible—?!
Bang!!
Four Arms stomped the ground and rushed forward at extreme speed, throwing another punch—
Flash!
He transformed into Ghostfreak mid-strike.
A soft, ghostly punch landed on Kevin's body.
At least—
That's how it looked to Kevin.
"Haha…"
Kevin scoffed, grabbing Ghostfreak's wrist with ease and smashing a punch into him.
"Looks like your broken watch isn't very smart, Ben Tennyson!"
"Annoying…"
Ghostfreak grimaced, his body twisting under the harsh sunlight!
Kevin lunged forward gleefully—
But Ghostfreak phased through the ground using sheer willpower!
Rumble!!
Kevin stomped down, shattering the ground and forcing Ghostfreak back out.
He swung another punch—
Whoosh!!
Light flashed.
Diamondhead appeared and took the hit head-on.
Then—
Nothing happened.
Bang!!
Diamondhead raised his arm, countless crystals erupting and smashing into Kevin one after another!
Throughout the entire battle—
Whoosh, whoosh, whoosh.
Ben's transformations kept switching uncontrollably.
One second he was Diamondhead.
The next, Wildvine.
Just as he tried to release hypnotic spores—
He turned into Heatblast.
This constant switching frustrated Ben immensely.
He felt like he had power—
But nowhere to use it properly.
The only thing he was thankful for was that the Omnitrix didn't randomly turn him into Gray Matter.
"Hahaha!! The Omnitrix is helping me now! Ben Tennyson—you're finished!"
Kevin was ecstatic.
Claws.
Punches.
Headbutts.
Knees.
Every part of his body became a weapon, mercilessly smashing into Ben.
This was proof—
Vilgax had trained his body to absolute perfection.
High above—
Alien X flew back and forth, anxiety creeping into his expression.
"Is Ben going to lose here…? If it really comes down to it, I'll step in and erase Kevin. That might even trigger a system mission…"
Damn it.
Alien X almost couldn't watch anymore.
His body tilted as he dove downward—
Just as he broke through the clouds—
Whoosh.
He corrected his course and flew back upward.
A confident smile appeared on his face.
"Alright. Ben can win. This is guaranteed."
Back on the ground—
Bang! Bang! Bang!!
Kevin smashed his fists into Four Arms relentlessly, treating him like a punching bag.
His expression was exhilarated.
His eyes burned with excitement.
No wonder.
No wonder Ethen liked treating enemies like punching bags.
Tormenting opponents—
It really was addictive.
Rumble!!
Kevin's muscles surged as his arms swung like battle axes, blasting Four Arms backward!
He smiled faintly.
"It's almost over, isn't it…?"
But—
Something was wrong.
"Hoo… hoo…"
Four Arms breathed heavily, heat radiating from his body as he raised all four arms defensively.
His muscles were tight.
Uninjured.
Unrelaxed.
In fact—
If you looked closely—
Every muscle on Four Arms' body…
Was becoming denser.
Stronger.
More explosive.
"…That's weird. But I'll still win."
Kevin muttered, forcing confidence.
After Ethen's beatdowns—
Enemies always collapsed.
So why hadn't this punching bag fallen yet?
"Power… Power from nowhere is pouring into my body…"
Four Arms growled, each breath fiercer than the last.
He could feel it.
He was getting stronger.
Every second.
Because of the Omnitrix's malfunction—
He could keep fighting longer than usual.
Slowly adapting.
Slowly absorbing the boost.
Maybe…
He really could win.
Whoosh!!
Kevin lunged again, throwing another punch.
This time—
Four Arms punched back.
Flash!
He transformed into Heatblast mid-swing.
"Heh, Heatblast? Punching me?" Kevin sneered.
Bang!!
Their fists collided.
Flames erupted violently from Heatblast's fist.
His arm muscles bulged—
And he actually held on for several seconds!
Then—
He retreated only slightly.
"…That's not right."
Kevin's expression finally changed.
Since when—
Could Heatblast fight him head-on in close combat?!
Alien X completely relaxed.
Because Kevin had been brutally suppressing Ben—
Pushing his body to the brink—
The Vilgaxian strength-enhancing potion, which should have been absorbed slowly—
Had accelerated.
It continuously reinforced Ben Tennyson's body.
As a result—
The average combat strength of all his aliens was rising.
"Ben can finish this." Alien X smiled faintly.
"I should head to the next battlefield."
His figure flashed as he flew off toward the distance.
The one he worried about most—
Was Ben.
Now that Ben was fine—
It was time to check on the second person he cared about.
Grandpa Max.
