The world around them ceased to exist. To the million shinobi watching from afar, the battle between Sasuke Uchiha and Madara Uchiha looked like the collision of two dying galaxies. The blue light of the Perfect Susano'o clashed against the jagged, black-silver aura of Sasuke's Nihilistic Reiatsu.
Madara stood atop the head of his Susano'o, his arms crossed, his Rinnegan spinning with a ferocity that defied his calm expression. Below him, Sasuke hovered in the air, his black wings beating slowly, his silver eyes reflecting nothing but the cold logic of Aizen's design.
The Clash of Ideologies
"You fight with borrowed power, boy!" Madara roared, his Susano'o drawing a massive blade of blue chakra. "Aizen turned you into a battery for his ambitions. You've traded your Uchiha pride for a hole in your chest!"
"Pride is a shackle for the weak, Madara," Sasuke replied. His voice didn't travel through the air; it vibrated directly inside Madara's mind. "You sought to trap the world in a dream because you were too afraid of the reality of loss. I have embraced the loss. I have become the Void itself."
Madara swung the Susano'o's blade. The air pressure alone leveled a mountain range ten miles to the west.
Sasuke didn't draw his sword. He simply extended his hand. "Cero: Amaterasu."
Black flames didn't just erupt; they were fired as a concentrated beam of spiritual erasure. When the Cero hit Madara's Susano'o, it didn't explode—it ate the chakra. The blue armor of the Susano'o began to dissolve into black smoke where the beam touched it.
The Secret of the Void-Sharingan
Madara's eyes widened. "It consumes chakra? Hmph. Then let's see you consume the earth!"
Madara performed a single hand sign. "Tengai Shinsei!" (Heavenly Obstacle Quaking Star).
The sky darkened. Two massive meteors, each the size of a city, began to descend from the upper atmosphere, pulled by Madara's gravitational command. The Allied Forces below screamed in terror, realizing that even the shockwave would kill them all.
Sasuke looked up. His left eye, the Void-Sharingan, began to bleed silver tears.
"Limbo: Zero."
In an instant, four invisible shadows of Sasuke—beings that existed in the world of Nothingness—flew upward. But unlike Madara's Limbo clones, these were made of Void energy. They didn't hit the meteors; they erased the concept of their mass.
The meteors didn't break. They simply turned into gray ash and vanished before they even touched the clouds.
The Final Evolution of the Sword
Madara landed on the sand, realizing his Susano'o was being eaten by the black flames. He dispelled it and drew his gunbai (war fan), charging at Sasuke with the speed of a lightning bolt.
"You're fast, kid! But can you handle the original?"
The two collided in a blur of Taijutsu. Madara's movements were a dance of ancient war—brutal, efficient, and perfect. Sasuke's movements were the flicker of a shadow—he didn't seem to move so much as he ceased to exist in one spot and appeared in another.
Sasuke drew his obsidian blade. "Resurrección: Segunda Etapa." (The Second Stage).
His black wings grew to twice their size, and a second hollow hole opened in the center of his forehead. His skin turned pitch black, and his eyes became glowing white slits.
"I am the end of your lineage, Madara," Sasuke hissed. He swung his blade, not at Madara, but at the air. "Lanza del Relámpago de la Oscuridad." (Lance of the Dark Lightning).
A spear of green-black lightning formed in Sasuke's hand. He threw it. The impact didn't create a fire; it created a vacuum. The Gedo Mazo behind Madara groaned as its arm was sucked into a miniature black hole created by the strike.
Madara stood his ground, his armor shattered, blood running down his face. He was laughing. "Yes! This is the dance I've waited for! Aizen may have made you a god, but I will make you a corpse!"
