Start From Naruto: Shino the Dominator

"My threads were absorbed and used against me? Interesting."

Finding the situation really intriguing, Kakuzu's eyes narrowed, yet the ever adaptable Kakuzu's reaction wasn't slow at all.

"Heh. The fake can never trump over the real."

Facing the sudden onslaught from a copy of his own ability, a wave of grey tendrils erupted from his own hands, intercepting the oncoming deluge of black tendrils.

The clash of power created a rather unsightly spectacle, a chaotic symphony of writhing darkness, where tentacles met tentacles as if they held grudges against each other!

"Resistance is futile. Be obedient, be my food!" Venom taunted, its words laced with a mix of sadistic delight and hunger.

More black and grey threads weaved out from their respective owners, each side struggling to gain an upper hand in this remarkable mimicry of technique!

Venom's black tendrils lashed out with unmatched quantity from every part of its towering body, each strike a ferocious combination of wild growth and raw strength.

On the other hand, Kakuzu, as the original owner, utilized his vast experience and unceasing grey tendrils to counter Venom's onslaught, gradually increasing the intensity as if testing the opponent's limits.

Watching from a distance, the expressions of Itachi and Kisame revealed a hint of surprise and apprehension.

Kisame, his eyes glinting with battle intent, interjected with a toothy grin. "This battle just got a whole lot more interesting. I can't wait to see how Kakuzu handles this. If he can't… Samehada is always happy to come out for a breather and... shave him to death."

Itachi didn't respond, but his eyes, ever calm and calculating, assessed the situation.

"What a strange life. It doesn't seem to be ninjutsu... is it body modification? A result of human experimentation? No… it seems like there are two lifeforms merged into one body – a ninja and an unknown biological mass. It also has an ability to imitate biological transformations like Kakuzu's threads… No wonder he became a target of invitation."

Now, the question is: Can it imitate other biological-related aspects, such as kekkai genkai? If so...

No, there must be a limit or weakness, just like everything else in this world. Otherwise, its existence must be erased.

Itachi's eyes flashed. Another target to put on his observation list.

Rustle! Rustle! The escalating clash between Kakuzu and Venom reverberated through the battlefield, their immense power colliding in a titanic struggle.

Suddenly, one end of the wave gave way, allowing the opposing wave to break through unhindered!

With a kick, Venom launched himself into the air, leaping above the river of tendrils rushing past below.

Mid-air, one of Venom's arms morphed into a writhing black mass, extending itself and hurtling downward with explosive force, only to narrowly miss Kakuzu and embed itself into the unforgiving earth near him!

Anchored to the ground, Venom's elastic arm recoiled like a rubber band, shooting Venom downwards with furious force and almost lightning speed!

Facing the sudden surprise attack that came in the blink of an eye, Kakuzu was actually left with no time to dodge!

Or maybe, he just didn't care to dodge. Locking his eyes onto his opponent, Kakuzu met Venom's attack head-on - fist to fist!

Pow! This time, the force unexpectedly sent Kakuzu sliding backward across the ground despite successfully blocking the onslaught unscathed!

Stabilizing the slight trembling of his hands, a menacing smirk crossed Kakuzu's face and he delivered an invitation laced with a veiled threat.

"I didn't want to resort to this, but it seems I have no choice. Prepare to witness my true power."

Kakuzu's back began to squirm and bulge, a telltale sign of the formidable power that lay hidden within.

His hand reached out, ready to remove his Akatsuki cloak, clearly intent on unleashing the beasts within him!

However, just before he could open the next stage of battle, a sudden female voice delivered itself through the forest, halting him in his tracks. "That is enough."

Kakuzu paused, his hand slowly lowering, his attention drawn to the source of the voice.

Next to him, a mass of white origami paper flowed down from the canopy of the forest, coalescing into a humanoid form, like an angel descending from the heavens above.

Soon, a woman clad in the Akatsuki cloak came into existence, her amber eyes observing everything as if she no longer held interest in anything in this world.

Yet, her neutral expression did nothing to reduce the charm of her beautiful face and striking features.

Standing out like a sore thumb amongst the other members of the group was her short, straight blue hair, elegantly styled in a bun and clipped with a large, light blue paper flower.

A hint of lavender eye shadow shaded her eyes, and a black labret piercing adorned her soft, lower lip.

Any horny men who sees her attractive face wouldn't be able to help but to take a gander at her figure.

Alas, most of her body was hidden beneath the Akatsuki robe, with the exception of her hands, with nails painted a vibrant orange, and an Akatsuki ring that was worn on her right middle finger, hinting at her identity with the displayed kanji symbolizing 'white.'

However, those privy to the truth knew her to be... Konan.

For those not in the know, she was just a pretty interesting kunoichi worth chasing.

Yet, Kakuzu stared at the blue-haired woman, showing zero signs of interest over her beauty just like the other men here.

"You really have a way of irritating me, you know that?"

Kisame, unable to resist a taunt, grinned mischievously and added, "It's no fun to end it so early, right Itachi-san?"

Itachi didn't say anything, but his gaze remained fixed on the co-leader of the Akatsuki organization, his perceptive eyes analyzing her presence and the potential impact she would have on everything.

Most importantly, he silently deciphered the secret nature of her technique like he always does with everyone else.

Ignoring the peer pressure, Konan focused solely on the still-aggressive Venom. "If you desire to continue, you will face all four of us."

Despite her cold treatment, the other three Akatsuki members still fell into position, boxing Venom in with a casual yet calculated formation.

Venom's eyes scanned the assembled group of solitary members, a twisted grin spreading across its visage.

Its menacing laughter echoed through the air, and its long, sinewy tongue flicked across its face in anticipation of the ensuing confrontation.

"More food? How interesting."
