Naruto: Check out these scenes!

[Uchiha Madara: Tsk, I can't believe a non-Uchiha is wielding the Sharingan. What a mockery.]

[Hatake Kakashi: Ahem...]

[Uchiha Izuna: Seventh Hokage, care to share how you dealt with this guy?]

[Uzumaki Naruto: In my timeline, I put a stop to the development of artificial eyes, and Katasuke-sensei kicked Teguse out of the research institute. As for [Zero], after Sasuke wiped them out, Merz ended up imprisoned in Kizuna Castle.]

"Naruto!"

"Got it!"

At Sasuke's call, a silent understanding passed between the two. They surged forward in unison, intent on quelling the impending crisis.

"Hehe, so you can sense the danger these eyes pose... but it's too late!"

Before they could even take a few steps, Naruto felt an unsettling swirl on the back of his right hand—a Mangekyo pattern sprang to life, and an uncontrollable flow of chakra began to escape him, cascading into Merz waiting grasp.

Simultaneously, countless shinobi across the ninja world, regardless of age or gender, experienced the same phenomenon; their chakra violently surged forth, crossing mountains and seas to funnel into Merz's body.

Merz, flooded with this overwhelming energy, radiated power—an intensity so formidable that even Sasuke faltered, momentarily caught off guard.

Like a supercharged warrior, engulfed in blue chakra flames, he chuckled darkly. "Now everyone in the ninja world is connected through the engraved Tsukuyomi. You must understand what this means."

As his chakra swelled, Merujin's aura solidified. "Their chakra are in my hands. I am able to draw forth from them as I please!"

"And with all this unwieldy power, I can activate the true might of the Mangekyō Sharingan! Even that sacred power will obey!"

As he spoke, the blue chakra morphed into a terrifying blood-red hue. Thick tendrils of energy coalesced, forming a sinuous skeleton. Gradually, layers of tissue emerged—blood vessels, muscles, and skin—until a towering red giant, more than fifty meters tall, loomed over them.

[Uchiha Madara: Susanoo?! Is it possible for those fake eyes to actually manifest it?]

[Uchiha Izuna: Why does Merz's Susanoo look different from my brother's?]

[Yagura: What an intimidating figure...]

"This is... impossible!"

"Is this for real?"

Both Naruto and Sasuke stood agape. It was one thing for Kakashi to conjure Susanoo using Obito's Mangekyō; it was another for Merz—an imposter—to wield it with artificial eyes.

However, it was clear that Merz's version of Susanoo was far from whole. Cracks ran through its form, revealing ribs jutting out distinctly.

"Well, it's not the original eye," Merz quipped, amusement dancing in his voice, "so it's a bit... different. But it should be more than enough to bury you here."

"You're that sure, huh?" Naruto challenged, furrowing his brow.

As if in response, Merz commanded Susanoo to draw a long sword. "Absolutely! After all, you're no longer the strongest of this current generation!"

With that, he unleashed a torrent of blinding energy as the weapon was unsheathed, a storm of force that threatened to slice everything in its path. Sasuke instinctively activated his own Susanoo, shielding everyone nearby.

Yet, upon resisting the onslaught, Sasuke realized with sheer horror that this storm was laced with an excess of chakra. When it collided with Susanoo, parts of its exterior were instantly shredded, revealing the stark unpredictability of their foe's power.

With a resounding crash, Sasuke's purple Susanoo was overwhelmed, practically dismantled in the face of the storm—a once-mighty base now reduced to chaos.

As silence fell, only a vast crater marked the location of what was once the Zero Organization base, with Merz's enormous red figure looming over the destruction.

"Is everyone alright?" Naruto pushed aside a massive rock, scanning the area. To his relief, he found only Sasuke nearby, a sense of dread creeping in as he noted the absence of Boruto and the others. Thankfully, he could still sense Boruto's chakra nearby.

"So resilient," Merz mused, gazing down at the exhausted duo. "But to me, you two are nothing but ants I can crush with a mere flick of my hand."

With that, the blood-red Susanoo lifted its sword, the scarlet light casting an ominous glow around Naruto and Sasuke, inducing a dread that felt almost tangible.

Understanding the oncoming devastation, both Naruto and Sasuke steeled themselves, pouring every last ounce of chakra into their defense.

The Nine-Tails manifested, cloaked in an azure glow, with Susanoo's ethereal armor enveloping it. A long sword materialized in the fox's grip, representing the combined might of Naruto and Sasuke—the Tailed Beast Suppression technique.

With a determined cry!

As the Nine-Tailed Fox raised its sword to deflect, the two massive blades collided with a cataclysmic force. their ground erupted; shards of earth splintered into the air as the strike pressed down. Despite the Kurama chakra mode's might, it found itself being forced into the ground under the intensity of Merz's assault.

As they struggled against the overwhelming might, Merujin's laughter echoed through the chaos. "Is this your resistance? You're just prolonging the inevitable, draining your remaining chakra only to cling to life for a heartbeat longer."

"It's tragic to witness the two of you, once monumental heroes, reduced to this."

"We need to focus!"

But there was no time for banter. Naruto and Sasuke were locked in a desperate struggle, together fighting tooth and nail against the impending doom.

[Uchiha Madara: Hmph, this situation reflects poorly on you, Seventh Hokage. You're not strong enough.]

[Senju Hashirama: But Madara, remember, these two have already fought to their limits before this encounter. Would we have managed better in our weakened state at the Valley of the End?]

[Uchiha Madara: Tsk!]

[Senju Tobirama: Scientific ninja tools? Now that's an interesting concept. I'd really like to meet the mastermind behind this innovation, Katasuke-sensei, was it?]

[Uchiha Izuna: White-haired, I never thought you'd be intrigued by such things.]

[Senju Tobirama: Am I just seen as someone disinterested in worldly matters to you Uchiha?]

[Uchiha Izuna: Isn't that the truth?]

[Senju Tobirama: Enough with this banter.]

[The Fourth Raikage: Is this the true potential of scientific ninja tools? We must return and delve into this research forthwith.]

[Onoki: We're definitely on the same page here.]

In the midst of the turmoil, Merz tightened his grip on Susanoo's massive hand, grinning with wicked glee. "Your era has ended! It's my time to rise!"

With that, he brought the red blade crashing down!

But just as the lethal weapon fell, it was suddenly deflected by something unseen. The shockwave granted the Nine-Tails a fleeting moment to regroup, just in time for it to bat the red sword aside.

Merz was taken aback, confusion flashing across his face. "…What just happened?"

As Naruto and Sasuke caught their breath, they turned in the direction of the unknown attacker, stunned to see a figure radiating blue chakra—its posture unwavering, ready to defend.

"Boruto?!"
