Ben 10: Carnitrix Without Downsides?

"Let's call it Gorebolt!" Ben shouted boldly. His uncanny talent for naming came through once again, saving Zack from his usual indecision.

Dr. Animo's face twisted with fury.

These people… in front of his precious prehistoric beasts… still had the nerve to name aliens? Were they really that carefree?!

Boom!

The Tyrannosaurus Rex stomped forward and charged at Zack's transformed figure—though there was now a flicker of hesitation in its eyes.

Meanwhile, dozens of mutated cockroaches buzzed around Zack, swarming in from every direction.

"All of you... get lost!"

Zack immediately curled into a massive spiked sphere—his armor bristling with blades—and hurled himself forward with explosive momentum!

CRASH!

The giant spiked ball smashed directly into the Tyrannosaurus Rex. In just one brutal impact, the colossal beast let out a pained roar, stumbling back, its body now riddled with dozens of deep, bloody puncture wounds!

"Don't even think about running!"

Zack rebounded off the ground like a living cannonball and slammed into the dinosaur again—then again!

This apex predator of the ancient world was being completely overpowered, thrashed back and forth like a ragdoll.

As for the mutated cockroaches?

They tried to dive in—but the sheer shockwaves of Zack's violent impacts shredded them mid-air, their bodies bursting apart before they could get close.

No chance.

Absolutely no chance of winning!

"Damn it…"

Dr. Animo cursed, leaping off the Triceratops in a panic. "Triceratops, go intercept Gorebolt! Cockroaches—take care of that Four-Arms!"

Surprisingly, the mutated prehistoric beasts and insects actually understood his complex commands!

The Triceratops immediately stomped forward, charging aggressively toward Zack.

"Triceratops, huh?"

Zack quickly adjusted his rolling trajectory, hurling his massive spiked form straight toward the oncoming behemoth!

In terms of size, the two were hardly comparable. If the Triceratops was a raging tiger, then Gorebolt looked more like a massive orange cat.

BOOM!

The two collided head-on—

And the Triceratops's massive frame skidded to a stop, barely managing to clash with Zack's form at all!

It couldn't even push him back.

It felt like slamming into a boulder.

Like crashing into a small mountain.

"RRooooAAHHHR!!"

The Tyrannosaurus Rex let out a thunderous roar and suddenly lunged from behind, jaws wide, trying to sink its teeth into Zack's exposed back—a sneaky ambush!

The dinosaurs were closing in, compressing Zack's space to roll and maneuver!

Meanwhile—

Mutated cockroaches swarmed Ben from above, persistently harassing him mid-battle.

He gritted his teeth and stumbled back, using gusts of wind from his powerful punches to swat them away, but he couldn't defend against the Mammoth charging in from the side.

"Ugh, these bugs explode into disgusting goop when I hit them! I can't take it anymore!"

Seriously, it was nasty beyond reason.

The tide of the battle had begun to turn.

The Tyrannosaurus Rex and Triceratops flanked Zack from both sides, locking him in and giving him no room to roll freely.

Ben, on the other hand, was getting smacked around now and then by the Mammoth's trunk. Though it wasn't a serious injury, it still stung.

"This is perfect!"

Dr. Animo clutched the gene variator on his head with glee, his eyes wide with excitement. "I, Dr. Animo, will finally claim victory! Hahahaha!"

At last—sweet revenge!

BOOM!

Suddenly, Zack launched himself into the air, curling once again into a massive spiked ball mid-jump!

He ricocheted off the heads of the Tyrannosaurus Rex and the Triceratops like a pinball—bang! bang!—before springing high into the air and soaring away from the pincer trap!

The two ancient beasts immediately roared in unison, charging after Zack as he bounced away.

"He's trying to escape! Don't let him get away!" Dr. Animo shouted, jabbing a finger in Zack's direction.

BOOM!

Zack landed hard in front of Ben, the shockwave so intense it made the two Mammoths hesitate and keep their distance.

Cough cough—"So… Zack," Ben muttered under his breath, lowering his voice quickly, "you handle the bugs, I'll deal with the rest! If we don't split up, we're toast!"

"Don't worry, Ben." Zack stood up slowly, resting a hand on the glowing pattern on his chest. "Watch me activate Killer Mode. I'll take down the trainer of these Pokémon myself."

"Wait, what the heck are Pokémon and a trainer?" Ben asked, visibly confused.

Whoosh!

A flash of light burst from Zack's body as a new alien slowly emerged from the glow. Its demonic grin made Ben shiver on the spot.

"Sorry," Zack muttered, voice distorted through his transformation. "Wrong channel."

"Huh?" Animo froze, his eyes locking onto the strange roller-like appendages on Zack's feet.

His face paled as he suddenly realized what was happening.

"Stop him!!" he shouted frantically. "He's switched to a speed-type!!"

Bang! Bang! Bang!

All the mutated cockroaches, the Tyrannosaurus Rex, the Mammoths, and the Triceratops—countless ancient and mutated creatures—assembled in front of Dr. Animo, forming a thick biological wall.

It was a grotesque but formidable barricade, enough to give Animo a sense of absolute security.

"Hah… it's done," Animo exhaled deeply, feeling a rare moment of relief wash over him.

"You look tense. Want a smoke?"

A hand appeared beside him, casually offering a cigarette.

"Oh—thanks. A smoke to calm the nerves is just what I—wait a minute…" Animo took it instinctively, but the moment his fingers closed around it, he froze.

This cigarette… It was the exact cheap brand only he bought. It had come from his own pocket.

And that hand… Looking closely—wasn't even human.

It was a massive, jagged claw.

"..."

Animo's heart thumped violently in his chest. Slowly, painfully, he turned his head.

Standing right beside him, face-to-face, was the MonXTR. Zack's error XLR8 transformation.

BANG!

Without hesitation, Zack threw a brutal punch, knocking Animo out cold on the spot. His claw followed up with a sharp slash—ripping the gene variator right off Animo's head.

With a metallic crunch, the device shattered to pieces.

And with it—the reign of chaos began to crumble.

All of the mutated creatures present suddenly lost their command structure, falling into chaos. They began to run and jump wildly, scattering in every direction.

"Alright," Zack muttered, raising a hand toward the transformation pattern on his chest. "Time to switch to Gorebolt and finish this—wait… I just got a better idea."

He paused, glancing into the distance to confirm that no one was around to witness what he was about to do.

Then, without hesitation, he charged straight toward the Tyrannosaurus Rex at full speed.

"Is he serious?" Ben stared, mouth agape. "He thinks the MonXTR can smash a T-Rex? That's gotta be a joke..."

Whoosh!

As red light surged, Killer Mode activated. Zack's form shifted mid-run—MonXTR  transforming into Gorebolt.

But this time, the booming Gorebolt retained the MonXTR's enhanced speed, blitzing forward like a missile.

BOOM!

He slammed directly into the Tyrannosaurus Rex.

The mighty dinosaur didn't even have time to roar. It was launched high into the air, its body torn and broken, vanishing moments later in a flash of energy.

Up in the sky…

The Tyrannosaurus Rex flew like a ragdoll, its expression dazed, its entire form mangled.

It soared—briefly.

Though its fate was sealed, some might say… the dragon had taken flight.

And for a member of the Tyrannosaurus Rex family…That was legendary.

The only one of its kind that had ever flown.

How awesome.

Bang!

Zack slammed into the Triceratops again, sending it soaring through the air before it crashed into a distant lake with a tremendous splash!

Even the two Mammoths weren't spared—he took them down one after another with ease.

Ben, no longer caring about how gross it all was, could only grit his teeth and start punching through waves of mutated cockroaches. "In that case… at least my kill count won't be worse than Zack's! Cough cough!"

"My goodness…"

Zack straightened up slowly, a grin tugging at the corners of his mouth. "The transformation speed in Killer Mode is just too strong!"

Ding! Host has neutralized Dr. Animo, defeated two Mammoths, launched a Tyrannosaurus Rex, and sent a Triceratops flying. Absolute rampage! Progress +1!

Template progress: 7/100.

New Extraterrestrials unlocked: Eye Guy, Wildvine, and Ditto!

"The template can still keep growing... I just need to take out more enemies!"

Zack clenched his fists with excitement, grinning from ear to ear. "Three new forms unlocked, heh~ This is amazing!"

Buzz buzz buzz~

The whir of helicopter blades filled the sky. Police cars rolled in from every direction. Every branch of law enforcement was converging on the scene.

Zack quickly calmed himself down and slipped away with Ben before the authorities could get a good look.

...

Meanwhile, Dr. Animo finally regained consciousness. He knelt on the ground, trembling, and looked toward the approaching police officers with... tears of joy!!

"You've finally come to save me!" he cried out emotionally. "I swear I'll do my research on those terrifying Extraterrestrials from behind bars! Lock me up, give me food and shelter, just—just don't let me out again!"

Prison, after all, came with three meals and a roof over his head.
