"..."
"Stop your arrogant talk!!"
Error Alien X suddenly felt an inexplicable, crushing pressure descend upon him.
Flustered and enraged, he completely lost his composure.
Vast divine power surged wildly from his hands as he slammed both arms downward toward Atomic X below!
"Divine Power Cannon!"
Atomic X calmly raised his left arm cannon. Divine power rapidly compressed inside the barrel, burning violently from within—
Rumble!
With a flick of his arm, the divine power shot out like a cannonball, colliding head-on with Error Alien X's attack!
The divine power cannonball exploded instantly, shattering Error Alien X's divine power in a single overwhelming strike!
Not only that.
The resulting shockwave surged forward violently, slamming straight into Error Alien X in midair.
"I can't dodge it… The shockwave's range is too big!!"
Shock and terror flooded Error Alien X's face. He raised both arms defensively, but he was still blasted backward by the impact!
"Take this!"
Atomic X vanished in a flash and reappeared directly above Error Alien X!
He lifted his massive axe high and brought it crashing down with terrifying force, cleaving straight toward Error Alien X's body!
"Even if you used a Doppelganger to modify and upgrade your body… you still won't hit me!"
Error Alien X snarled furiously. His body moved on instinct, narrowly dodging the axe.
"Is that so?" Suddenly, facial features appeared on the axe itself. The Doppelganger spoke with a playful tone.
Puchi!
The divine power axe curved unnaturally in midair, redirecting itself and cleaving straight toward the dodging Error Alien X!
"Shit!!"
Error Alien X hurriedly teleported, desperately trying to escape the strike.
But the axe twisted and followed relentlessly, sticking to him like a living thing!
In other words—
Atomic X originally couldn't land a hit on Error Alien X.
But the Doppelganger didn't just break his physical limits.
It granted automatic target tracking!
With this, Error Alien X's Danger Sense was completely countered!
"Phew…"
Dr. Paradox let out a slow breath.
"Unless something unexpected happens, Error Alien X is guaranteed to lose."
"Brother Ben is a trump card—just like Ethen. Defeating a second-generation Error watch user isn't surprising."
He paused, then frowned.
"However… the second-generation Error watch also possesses an Ultimate Evolution function. But Ultimate Evolution shouldn't apply to Error Alien X, right?"
Dr. Paradox muttered to himself.
Ultimate Evolution involved forcing a specific DNA into an unimaginably harsh environment to trigger adaptive evolution.
But what kind of environment…
Could possibly force Alien X to evolve?
Even a flawed version of Alien X shouldn't be capable of encountering such an environment!!
The battle dragged on for a long time—until finally.
Atomic X raised both arms overhead.
His arms rapidly merged, reshaping and reconstructing themselves until they transformed into a massive, terrifying Nuclear-Powered Gatling Gun!
"A… Gatling gun?"
Error Alien X's eyebrows twitched violently, his expression looking as unpleasant as if he'd just eaten shit.
"You're pretty good at dodging, huh? Then let's see how you handle this storm-level offense, you error monster."
Atomic X's expression radiated absolute dominance, his voice booming with authority!
Bang! Bang! Bang!!
The Nuclear-Powered Gatling Gun roared to life, firing an endless barrage of divine power bullets!
Hundreds—thousands—an unbroken stream of bullets rained down like a torrential storm!
Cold sweat instantly soaked Error Alien X's forehead.
This… how the hell am I supposed to dodge this?!
Bang! Bang! Bang!!
The first wave slammed into him violently.
Error Alien X twisted and dodged frantically, but bullets still tore through his body relentlessly.
Over time…
His eyes turned crimson.
Snarling like a beast, he charged straight toward Atomic X.
"If I can't dodge—don't think you'll come out unscathed either!!"
Even with his body riddled with holes, he forced himself forward, pushing through the firestorm!
The moment the two figures closed in—
Whoosh!
Error Alien X opened his blood-soaked mouth, fangs snapping down viciously.
Crack.
Atomic X's feet suddenly shifted.
They had already been modified by the Doppelganger, equipped with Rocket Thrusters!
Without even moving his body, Atomic X relied on the thrusters to evade the bite effortlessly.
Then, he resumed suppressing Error Alien X with continuous firepower!
"Did you really think you were the only one who could dodge by instinct?"
"Don't forget—your opponents are three Ben Tennysons."
"Do you honestly think you can win?"
The voices of the two Doppelgangers echoed one after another, overflowing with confidence!
Atomic X smiled faintly.
"I'm actually going to lose again…"
"Huh… why did I say 'again'?"
Error Alien X's entire body burned with pain. His vision blurred rapidly.
Ten minutes later—
His body plunged from the sky, crashing violently into the ground.
Blue Class and Full Class had already deactivated their transformations, staring at Error Alien X with exhaustion written all over their faces.
Atomic X landed shortly after, looking down at him.
Biu~ biu!
A crisp notification sound rang out as bloody light flashed.
Error Alien X's transformation deactivated.
What appeared before them—
Was a boy with an unnaturally thin face, skin pale and bloodless, eyes lifeless and spirit completely drained.
It was Ben Tennyson, tortured into misery by the Error watch.
"How could it be… So miserable."
Atomic X stared at Error Ben, his expression heavy.
"Has he really been tortured that badly?"
"Damn… this guy's pitiful."
Blue Class turned away, unable to keep looking.
Full Class stayed silent, a deep sense of empathy filling his chest.
Although he himself hadn't been tortured by the Error watch…
Seeing another version of himself in this state still hurt.
"We won!!"
Dr. Paradox burst into laughter, his face filled with wild joy.
"Now, as long as we clean up the source of pollution, Ban, the Multiverse will finally be safe!! Alright, I'll do it now—"
"Wait. Clean up?" Atomic X suddenly turned and stared at Dr. Paradox.
"Doctor, I think there's a better way. Directly erasing him? Physical-level elimination?"
"He's already suffered enough!" Full Class spoke up sharply, more emotional than ever.
Dr. Paradox froze, then hurriedly explained, bitterness creeping into his expression.
"This is a last resort. If we clean up the pollution source and I deploy a normal Omnitrix into this universe, it can be restored."
"Otherwise, the Error watch will eventually return."
"We can't erase him! And besides 'having no choice'—there has to be another way we haven't discovered yet!!"
Brother Ben declared firmly.
