The atmosphere grows tense as Naruto, Sasuke, Obito, Kakashi, Madara, Hashirama, Hagoromo, and Hamura all stand ready to face Brown Zetsu. Their combined strength is formidable, but everyone knows this won't be a simple sparring session.

Madara sneers, his Rinnegan gleaming. "Let's see how strong this evolved Zetsu really is."

Hashirama cracks his knuckles, a confident smile on his face. "Let's make this a good one, shall we?"

With a swift nod, the battle begins. This work was created by shredder121

Naruto and Sasuke charge forward first, their combined powers sending a wave of energy through the air. Sasuke uses his Rinnegan to try and warp Brown Zetsu's movements, while Naruto summons Kurama's chakra, charging at him with a Rasengan.

But Brown Zetsu quickly shifts into a defensive stance, dodging their attacks with ease. In a flash, he counters with a wave of energy, sending both Naruto and Sasuke tumbling backward.

Kakashi and Obito rush in next, with Obito using his Kamui to phase in and out, trying to catch Brown Zetsu off guard. Meanwhile, Kakashi uses his Sharingan and Chidori to try and hit him from different angles.

However, Brown Zetsu evades every strike with incredible precision, his body flowing like liquid as he dodges the attacks. His own counterattacks come fast and hard, forcing Obito and Kakashi to retreat.

Madara, seeing the speed of Brown Zetsu's evolution, steps forward, using his own Susanoo to try and trap him. Hashirama, not one to back down, summons his Wood Style and adds his strength to the battle.

But in the blink of an eye, Brown Zetsu shifts. The moment he does, his body pulses with an overwhelming surge of energy, evolving into a Golden Zetsu.

The power surge is almost tangible, as his golden form radiates with raw strength, far surpassing any of them. In that instant, Brown Zetsu becomes a fully evolved Golden Zetsu.

Before anyone can react, Golden Zetsu moves faster than all of them combined, overwhelming the group. His attacks land with precision and power, sending the strongest ninjas crashing to the ground. In a matter of moments, Naruto, Sasuke, Obito, Kakashi, Madara, Hashirama, Hagoromo, and Hamura are all overwhelmed and on the defensive, unable to land a single effective blow.

The fight is over in just five minutes. Golden Zetsu stands tall, his glowing golden form radiating victory. His enemies are all battered, breathing heavily and unable to continue.

Brown Zetsu, now fully evolved, gives a cold, emotionless look at the defeated warriors. "You are strong, but not strong enough. This is the power of a fully evolved Zetsu. Imagine facing dozens of them in battle."

Madara, gasping for breath, clenches his fists in frustration. "This is beyond anything I imagined."

Hashirama stands up, wiping the dirt from his clothes. "This kind of evolution... it's terrifying."

Hagoromo looks thoughtful, his hands clasped behind his back. "If this is the future of the Zetsu, the world will be in grave danger."

Sasuke, still recovering, eyes Brown Zetsu with intense focus. "We need to train harder. If this is just one of them, we won't stand a chance against an army of these things."

Naruto, grimacing in pain but still optimistic, grins through it. "Next time, we'll win. We just need to push ourselves further."

Brown Zetsu turns to leave, clearly satisfied with his display of power. "The real battle is not here. You must prepare for Isshiki and the future. But remember, when you fight Zetsu, you are not only facing power. You are facing evolution."

Tsunade, who had been watching from the sidelines with the others, mutters under her breath, "This is too much... they can evolve, and there could be millions of them."

Hashirama turns to the group, concern etched on his face. "This is only a taste of what's to come. We need to rethink our strategy and prepare for the worst."

The group agrees silently, the weight of the situation sinking in. This isn't just a battle for survival anymore—it's a battle against an ever-evolving enemy. Isshiki is still out there, and with the growing strength of the Zetsu, the stakes have never been higher.
