The true form of the Eight-Tails was that of a massive ox with eight octopus tentacles. Once, it had two horns, but during a previous rampage by the former Jinchūriki, Blue B, the Fourth Raikage, A, had severed the left horn in battle.
Now, only one horn remained.
The reason Blue B had gone berserk in the first place was intricately tied to Orochimaru. It was through Blue B's death that Killer Bee was selected as the next Eight-Tails Jinchūriki at a young age. And he lived up to the expectations—becoming the one man able to perfectly control the Eight-Tails.
But now, even this man, driven to desperation by Obito, revealed the full form of his Tailed Beast without hesitation.
"Disappointed in me? Think I destroyed everything? You think the Jinchūriki's real form is a monster? Look closer! The Jinchūriki changes, huh?!"
Killer Bee twisted his massive body, snorting hot steam from his nostrils.
Obito smirked. "Still breathing out of your nose, huh? You're definitely a bull-headed freak, but..."
Fwoosh! Five clusters of azure-blue flames flared to life from his fingertips. Obito crouched and slammed his palms to the ground.
"I won't let you run rampant any longer."
Uchiha Flame Formation!
A karmic flame erupted from the earth, morphing into a crimson lotus-shaped barrier that engulfed most of the Yunlei Gorge.
Obito had sealed the battlefield, isolating it to avoid involving A Fei and Maoyue Xiyang again.
Outside the barrier, Maoyue Xiyang exclaimed, "That barrier's stronger than the Four Violet Flame Formation! And he activated it solo?!"
A Fei muttered, "It's still a step below the Four Red Yang Formation, but it should be more than enough to hold off the Eight-Tails' Tailed Beast Bomb."
Inside, only Obito and the Eight-Tails remained.
Obito stood tall. "Let's enjoy this one-on-one, shall we? Don't disappoint me, Eight-Tails."
"I'm going to blow you to pieces!" The Eight-Tails roared, gathering terrifying chakra into its mouth.
This was no half-formed technique. This was a true Tailed Beast Bomb, a catastrophic energy sphere capable of leveling a mountain.
Obito's eyes blazed. "Yes. That's it."
Fwoom! Blue chakra flames enveloped Obito's body, rising into a massive form—the Crow Tengu Susanoo. A monstrous behemoth rivaling the Eight-Tails in sheer size.
The mountain beneath them groaned and crumbled under the strain of the two titans, and that was just the beginning.
The Eight-Tails devoured its own Tailed Beast Bomb and unleashed it in a beam of golden destruction!
BOOM!!!
The entire barrier rippled like a wave. The walls of the Uchiha Flame Formation trembled but did not crack.
With no escape, the energy pierced the top of the barrier and shot into the sky, exploding like golden fireworks that rained back down to earth.
BOOM! BOOM! BOOM!
Explosions erupted in all directions, quaking the ground itself.
"What level of battle is this..." Maoyue Xiyang murmured, his hands trembling as he gazed at the opaque barrier.
Inside, the Crow Tengu Susanoo still stood. Without even drawing its sacred weapon, it had absorbed the Eight-Tails' full-powered Tailed Beast Bomb!
From within, Obito looked calmly at the smoke-covered Eight-Tails. "I thought you'd have more power than this. But if that's all, then allow me..."
Shing! Shing! Shing!
Three black Kamui Shuriken formed in the hands of the Crow Tengu.
Kamui Shuriken: Triple Throw!
The Eight-Tails wasn't about to back down.
Quick-Fire Tailed Beast Bombs: Triple Shot!
BOOM! BOOM! BOOM!
As the bombs collided with the Kamui Shuriken, they were swallowed into spiraling space-time vortexes—neutralized.
Inside the shared mental realm of Killer Bee and the Eight-Tails:
Killer Bee broke into a cold sweat. "Those things hit us, we're toast."
The Eight-Tails grunted. "That black shuriken depends on that chakra giant. We have to destroy it first!"
"But its defense is way beyond the skeletal form we've seen before."
"Then we'll need a stronger Tailed Beast Bomb—but in this damn barrier, the blast would hit us too. We'd injure him and cripple ourselves!"
Killer Bee thought for a second. "If raw power won't work, let's seal it. Use that technique."
Sealing Technique: Billions of Wraths Binding Chains!
ROAR!! The Eight-Tails opened its mouth and spewed an immense volume of black ink, which quickly spread toward the Susanoo.
"Hmm?" Obito moved Susanoo back.
But the ink morphed into eight black octopus tentacles, ensnaring the Susanoo and soaking it in inky darkness.
"What is this...?" Obito narrowed his eyes.
"It's done. Count to three, and that thing'll be completely stiff, sealed by Eight-Tails' chakra."
"One!"
"Two!"
Just as the inky seal neared completion, Obito closed his eyes. Then reopened them—now blazing with overwhelming power.
Susanoo Sacred Weapon: Kyūta Divine Sky Mirror!
SHOOM! A vortex of divine energy exploded from the void. The ink reversed course, sucked into the vast aegis wielded by the Susanoo.
"What the hell!?" both Killer Bee and the Eight-Tails exclaimed.
"Divine Mark—Eightfold!" Obito's gaze darted from one tentacle to the next.
In moments, each of the Eight-Tails' limbs had been marked.
A black magatama jewel formed in the left hand of the Susanoo.
Susanoo Sacred Weapon: Kyūta Kamui Magatama!
The magatama was hurled!
The Eight-Tails fired another Tailed Beast Bomb in defense, but the magatama pierced straight through it.
"It went through?! Damn it—dodge!!"
The Eight-Tails turned and ran through the barrier.
But then—the magatama split into eight.
"NO WAY!!!" The Eight-Tails panicked.
BOOM! Eight magatama struck all eight tentacles. Eight spatial vortexes opened and ripped them off, absorbing them into oblivion.
The earlier Tailed Beast Bomb was also sucked into the Divine Sky Mirror's vortex.
Inside the Susanoo, Obito was gasping, blood flowing from his eyes. His pupil power was nearly spent, but unlike before, the Susanoo remained.
"Damn beast... I'll tear you apart! You stupid, dumb brute!" The injured Eight-Tails went berserk, summoning terrifying chakra.
Obito stared at him. "You're completely unhinged. Will you really overdraw your power to use the third artifact...? No. Not needed."
He formed a hand seal over his chest.
Ninjutsu: Hidden Mist Technique!
The entire barrier was blanketed in fog.
Then he formed another seal.
Shadow Clone Technique!
Poof! A shadow clone emerged.
"This... is the correct way to use Kamui." Obito vanished into the space-time vortex of his right eye, leaving only the clone inside Susanoo.
Outside the barrier, Maoyue Xiyang looked anxious. "What's going on in there?"
Vwoop! Obito reappeared beside him.
"You're here?! Where's the Eight-Tails?"
"He'll destroy himself soon. But let's move you all out of harm's way first."
Fwoop! Obito teleported A Fei, Maoyue Xiyang, and himself into another space.
Inside the barrier, unaware of the trick, the frenzied Eight-Tails screamed:
"Continuous Tailed Beast Bombs!!"
BOOM! BOOM! BOOM! BOOM!!
The Crow Tengu Susanoo was obliterated, its remains reduced to nothing in the ensuing rampage.
CRACK! Even the Uchiha Flame Formation began to break down under the pressure, spiderweb cracks forming before it shattered completely.
RUMBLE! Without the barrier, the explosion flooded outward, erasing peak after peak.
Yunlei Gorge vanished. The shockwave even reached Amegakure, ten miles away.
In his office, Fourth Raikage A was lifting weights when the building quaked. Debris fell around him.
"What in the world?!" He looked out, seeing a blinding light on the horizon.
His eyes widened. "Yunlei Gorge! Something's happened!!"
CRASH! He burst through the wall and dashed out.
It took a full eight minutes for the light to fade.
Vwoop! Obito reappeared midair, landing on a chunk of floating debris.
Yunlei Gorge... was gone.
All that remained was endless sea.
Debris floated in the water—remnants of what once was.
Obito looked around solemnly. "Only by facing a Tailed Beast head-on can you understand their true power. This much destruction... and it wasn't even whole."
He narrowed his gaze at Killer Bee, bloodied and unconscious on a slab of rock.
"Let me collect this scattered piece of power first..."
Vwoop!
Inside the spiritual world, Killer Bee lay silent.
"Bee!! Stay with me! I'll use my tentacle clone to rescue you!" The Eight-Tails yelled.
But then...
"Too late," Obito's voice echoed.
"You! How are you here? Why are you still alive?!" the Eight-Tails howled.
"With the power of the Sharingan, entering this space is nothing. And... is this the so-called 'Iron Armor Seal'?"
Obito stepped past Killer Bee, toward the armored Eight-Tails.
His masked left eye gleamed.
Kamui: Armor-Breaking Seal!
