"ROAR!!"
Ultimate Spider Monkey let out a savage roar, swinging his massive fist down at Ethen.
Thanks to Ultimate Evolution, his raw punching power far surpassed strength-based aliens like Four Arms or even Way Big in short bursts!
BANG!!
Ethen thrust his spear forward.
Flames erupted, colliding head-on with Ultimate Spider Monkey's heavy fist!
Fire and shockwaves exploded outward, forming a violent firestorm that swallowed the battlefield!
Several flames landed on Ultimate Spider Monkey—
But failed to ignite his fur.
After countless rounds of evolution, his body had long since developed fire resistance.
"DIE!!"
Snare-Oh lashed out from the side, bandages snapping around Ethen's waist!
Ethen sneered.
"Thanks."
WHOOSH!
Instead of resisting, his body floated upward, letting the bandages pull him—
Then he twisted midair and aimed his spear straight at Snare-Oh!
"Not good!!"
Snare-Oh dove aside at the last second, barely avoiding the thrust!
"Idiot! He's not afraid of you at all!"
Ultimate Spider Monkey shouted in frustration, spider spikes rising behind him as massive webs blasted toward Ethen!
"Fire doesn't work?" Ethen's lips curved into a grin.
"Then let's switch it up."
The flames around his body extinguished.
In their place—
Diamonds spread across his armor!
The spear in his hand reformed, reshaping into a specialized heavy crossbow!
CRACK!!
Diamond-tipped bolts locked into the Prototype Tool.
As the webs closed in—
Ethen raised the crossbow and fired!
BOOM!!
The diamond bolts ripped through the air, trailing sparks and lightning!
Webs shattered instantly—
BANG! BANG! BANG!!
Bolt after bolt slammed toward Ultimate Spider Monkey!
"He can do THAT too?!"
Ultimate Spider Monkey dodged desperately, barely avoiding being skewered.
"Still not enough?" Ethen smiled wider. "Then how about this."
The crossbow reshaped again—
Becoming a diamond Gatling gun!
The barrel spun.
BANG BANG BANG BANG!!
A storm of diamond bullets flooded the battlefield like a metal tsunami!
Ultimate Spider Monkey could no longer dodge.
He crossed his arms, grunting in pain as bullets slammed into him nonstop!
As for Snare-Oh—
He was instantly swept aside, blasted into the ground and pinned there, completely unable to move.
Ethen's combat power—
Was terrifying.
Gwen Tennyson stared in shock.
Relying only on ordinary alien DNA, the Prototype Tool, and pure combat skill—
Ethen was actually suppressing an Ultimate Alien.
And he even held a slight advantage.
Only a slight one—
But still an advantage.
He just couldn't finish Ultimate Spider Monkey quickly.
The reason was simple.
Vilgax had eaten a full Way Big attack head-on.
Ultimate Spider Monkey, on the other hand, had been on guard the entire time—
Preventing Ethen from using Way Big's power.
That difference alone changed everything.
"As long as I stop him from using Way Big and drag this out…"
Ultimate Spider Monkey steadied his breathing.
"I can win."
Ethen exhaled slowly, calculating.
"I need to end this fast…"
WHOOSH!!
A nuclear blast suddenly flew in from afar!
RUMBLE!!
The explosion swallowed both Ethen and Ultimate Spider Monkey!
"DAMN IT!!"
Ultimate Spider Monkey burst out of the blast, cursing loudly.
"Nega Ben! Stop throwing nuclear energy everywhere! You almost hit me!!"
But then—
The explosion began to fade.
"…Huh?"
"Why is it so weak?"
Ultimate Spider Monkey stared in confusion.
As the smoke thinned—
Ethen's figure emerged.
Electricity crackled violently around him.
On his armored palms—
Metallic pins extended from each finger.
"…That is—" Ultimate Spider Monkey swallowed hard. "Buzzshock…?"
"Ever been electrocuted so hard you fly?"
Ethen smiled.
The Prototype Tool covered his fingers, forming ten-finger turrets.
RUMBLE!!!
Electric cannons fired simultaneously!
Ten streams of devastating electricity merged into one catastrophic blast—
Slamming straight into Ultimate Spider Monkey!
"GRAAAHH!!"
Ultimate Spider Monkey was launched like a missile, tearing through buildings one after another!
Finally—
Hundreds of meters away.
He crashed into a wasteland and lay motionless, smoke rising from his fur.
"Ultimate Aliens… Aren't invincible after all."
His eyes dimmed.
And he passed out.
"Ding. Congratulations to the host for completing the mission!"
"Host has gained 60 Reward Points!"
Ethen's face lit up.
"Finally… sixty points."
Pink light flickered.
With a crisp sound, the Upgrade armor disengaged, returning him to normal.
Ethen smiled calmly.
"Even without transforming… I can still fight."
CRACK!
The Prototype Tool reconfigured again—
Becoming radiation-proof combat armor that wrapped around his body.
He walked forward unhurriedly.
Not far away—
Rath had Four Arms pinned to the ground, punching again and again!
Four Arms roared in pain, claws tearing back desperately—
Only to make Rath angrier.
"You're hurting LORD RATH!! I'LL BEAT YOU TO DEATH!!"
The more pain Rath felt—
The stronger he became.
Four Arms couldn't keep up.
"Hey, Rath."
A cold voice sounded behind him.
"What?! You dare call LORD RATH BY NAME—?!"
Rath turned—
BANG!!
Ethen's kick landed precisely on Rath's weakest point.
"OOWWW—!!"
Rath's entire body convulsed.
He clutched his legs, trembling violently—
And collapsed to his knees.
"Haha," Ethen chuckled. "Hit your weak spot. Can't even rage now, huh?"
"You—!!"
Rath tried to stand.
BANG BANG BANG!!
Punches.
Kicks.
Every strike landed on Rath's critical points.
Ethen beat him straight into the ground—
Unable to move.
Four Arms stared, dumbfounded.
Those methods…
Were vicious.
Just watching made his body ache in sympathy.
"Ding. Congratulations to the host for completing the mission!"
"Host has gained 15 Reward Points!"
Ethen stopped at last.
"…Only fifteen." He sighed slightly. "Too weak."
He clapped his hands together.
"Next."
"Next."
And charged toward another battlefield.
