Naruto: Transmigrated as Obito with the System

As Obito momentarily let his focus waver, Roshi seized the opportunity.

In his hands was a thin lava staff, which he swung down fiercely at Obito.

"Swoosh!"

Obito quickly raised his fan to block the attack, only to realize the imagined brute force never arrived.

What seemed like an overwhelming strike was merely a feint.

In a flash, the lava staff redirected mid-swing, arcing toward Obito's face like a rainbow slicing through the air.

"Swish!"

Faced with the lightning-fast attack, Obito instinctively tapped his toes to the ground and leapt back, narrowly evading the strike.

"Phew, that was close! Almost had to phase through it..."

He had come here to experience Roshi's Lava Release firsthand. Turning on his intangibility would've taken the fun out of it.

Capitalizing on his momentum, Roshi pressed forward relentlessly.

The lava staff jabbed, swept, slashed, and swung, forcing Obito into a purely defensive stance.

"Boom! Boom! Boom!"

In mere minutes, the two had already exchanged over a hundred blows.

While Obito's mastery of Lava Release wasn't as refined as Roshi's, his terrifying physical capabilities allowed him to hold his ground, resulting in a stalemate.

Roshi's expression grew grave. After so many exchanges, he still hadn't managed to overpower Obito.

He couldn't afford to drag this out any longer. It was time for that technique.

"Son Goku, lend me your strength!" Roshi called out in his mind.

"I'm ready!" replied the Four-Tails.

The next moment, an overwhelming surge of chakra erupted, and a menacing aura flooded the battlefield.

"Whoosh! Whoosh!"

The Lava Armor encasing Roshi was replaced by a sinister coat of crimson chakra.

On all fours, his body arched slightly, and four scarlet tails swayed ominously behind him.

Half-Tailed Beast Form!

"Seriously?! Going straight to half-tailed beast mode? That's dirty..." Obito muttered, clearly unamused.

But Roshi had no intention of playing fair.

The seasoned fighter opted for a sneak attack.

"Mini Tailed Beast Bomb!"

The half-transformed Roshi opened his mouth and spat out a small, purple sphere of compressed energy.

"Whoosh!"

The terrifyingly dense projectile tore through the air, hitting Obito in less than three seconds.

But instead of panic, Obito's face lit up with excitement.

"Hahaha! Finally, I get to use this move!"

Roshi blinked in confusion, watching as Obito gripped his Uchiha fan tightly.

Like a tennis player returning a serve, Obito swung the fan with precision, smacking the Tailed Beast Bomb back toward its owner.

"Uchiha Reflect!"

The purple sphere rocketed back toward Roshi with alarming speed.

"...???"

"Boom!"

A blinding explosion erupted as the bomb detonated inches away from Roshi, its devastating force flinging him backward.

Though not gravely injured, Roshi was furious. The sheer disrespect of Obito's counterattack stung more than the blast itself.

Letting out a roar of frustration, Roshi's chakra surged again, and his body began to grow.

"Graaahhh!"

Obito's pupils contracted slightly.

"No way... Full Tailed Beast Transformation?!"

In a matter of moments, Roshi's form shifted, expanding rapidly until he took on the towering figure of a crimson ape—the true form of the Four-Tails, Son Goku.

"Boom!"

The giant ape slammed into the ground, shaking the earth beneath them.

Standing over thirty meters tall, the beast exuded raw power, its muscular body and four swinging tails radiating an aura of primal ferocity.

Looking down at the ant-sized Obito, the Four-Tails let out a guttural grunt of confusion.

"Hmm?"

Rather than fear, the tiny figure below seemed even more exhilarated.

Obito clasped his hands together, his voice trembling with excitement.

"You started this mecha battle... Don't regret it now!"

"Wood Release: Great Forest Crumbling!"

The ground beneath their feet quaked as enormous trees shot up, their roots twisting and branches spreading into a dense forest.

Roshi frowned, unease creeping into his expression.

"Wood Release? The First Hokage's technique? A dual Kekkei Genkai?"

In his mind, Son Goku growled anxiously.

"Roshi, finish him quickly! We can't let him continue!"

The Four-Tails' memory of being subdued by the First Hokage made its anxiety palpable.

Roshi nodded gravely.

"Got it!"

The giant ape leaped into the air, its massive frame moving with surprising agility as it traversed the forest.

In no time, it loomed above Obito, its colossal fist raised high.

"Wham!"

But just as the devastating punch was about to land, it came to an abrupt halt.

"...What?!"

It wasn't hesitation or second thoughts. The massive fist simply couldn't move.

A giant wooden hand, formed from twisting roots and branches, had latched onto the ape's arm like an iron shackle.

"Wood Release: Wood Human Jutsu!" Obito declared with a grin.

Towering even higher than the Four-Tails was a gargantuan wooden human. Its golden eyes gleamed menacingly as it locked its gaze on the crimson ape.

No matter how hard the Four-Tails struggled, it couldn't break free of the human's grip.

"This... this is impossible..." Roshi muttered, disbelief washing over him.

The Four-Tails, known for its monstrous strength, was being overpowered.

Son Goku roared in frustration.

"Roshi, give it everything you've got! We can't afford to lose here!"

Breaking free with a final surge of strength, the crimson ape retreated momentarily.

But Obito, standing atop the wood human's head, merely laughed.

"Ahahaha! You're the first to witness this next move, Roshi-senpai. Try to keep up!"

A torrent of blue chakra erupted from Obito, enveloping the massive wood human.

Clapping his hands together, he shouted:

"Susanoo!"

Armor formed around the wooden colossus, outfitting it with the visage of a fearsome tengu warrior.

Drawing a massive blade from its back, the armored human advanced toward the Four-Tails, its eyes glowing with murderous intent.

Inside Roshi's mind, Son Goku's voice trembled.

"This level of chakra... Is he a Tailed Beast too?!"

"And that combination of techniques... How could one person possess them both?!"

Roshi clenched his fists.

"Son Goku... Can we win this?"

The Four-Tails sighed deeply.

"At this point, all we can do is try..."

The crimson ape conjured a lava staff in its hands, the molten rock solidifying into a formidable weapon.

Letting out a battle cry, the Four-Tails lunged at the armored human.

"Clang! Clang! Clang!"

The clash of titans began, each strike sending shockwaves through the battlefield.

The armored wood human swung its blade with relentless aggression, while the Four-Tails wielded its staff defensively, forming a nigh-impenetrable barrier around itself.

And so, the earth trembled under their monumental duel.
