The snow-covered forests of Sokovia were alive with chaos. Explosions ripped through the cold air as the Avengers charged forward, their sights set on the HYDRA base nestled among the mountains. Leading the charge were Captain America and Iron Man, shield and repulsors blazing. Thor flew overhead, lightning trailing in his wake, while Black Widow and Hawkeye coordinated their strikes from the ground. Hulk smashed through barriers like paper, and beside them all, a new warrior fought silently—Itachi Uchiha.
Wearing a dark cloak that billowed in the icy wind, Itachi's crimson Sharingan eyes scanned the battlefield. Each movement was calculated, every attack precise. With a single glance, he predicted enemy trajectories. His hands moved in swift signs, summoning black flames—Amaterasu—that consumed HYDRA's mechanized weapons. Unlike the others, Itachi made no sound. His presence was like a ghost, unstoppable and eerie.
Inside the HYDRA facility, Baron von Strucker watched the monitors with growing concern. "They have brought a new ally," he muttered. "One with powers we cannot comprehend."
The septer glowed with alien energy behind him. Wanda and Pietro Maximoff stood near, watching their leader in silence. Pietro vibrated with barely controlled speed, while Wanda's red aura pulsed with anticipation.
Outside, as Captain America deflected bullets and knocked enemies unconscious, Itachi suddenly halted. A vision flickered in his mind—his brother Sasuke.
"Sasuke... Are you safe in your world?" he thought. "I am not sure why I was brought here, but I sense no sickness, no weakness. My body is whole. My mission continues."
An enemy lunged at him. Itachi activated his Susanoo—a massive ethereal warrior enveloped him, wielding a spectral blade. The attacker was flung away like a ragdoll.
Iron Man landed beside him. "You're really quiet, Dracula. But I'm starting to like you."
Itachi gave a faint nod, but his eyes never left the battlefield.
In the depths of the base, Thor's hammer shattered doors as he led the charge inside. They reached the septer, glowing with Tesseract energy. Wanda and Pietro made their move.
Pietro blurred forward, punching Captain America off his feet. Wanda held out her hands toward Thor, invading his mind with visions. But as her power reached toward Itachi, she faltered. His Sharingan countered her manipulation, reflecting back a memory of her own—a twisted mirror.
She stumbled, gasping. "What... are you?"
"A shadow of another world," Itachi replied calmly. "But I am here to protect."
Wanda retreated, shaken.
The battle ended quickly after that. Pietro vanished with his sister, and the Avengers secured the base. Baron von Strucker surrendered, seeing the overwhelming odds.
As they regrouped outside, Tony quipped, "Another HYDRA base down. What's next?"
Thor held the septer in his hand. "This power must be returned to Asgard. It is too dangerous."
Itachi stepped forward. He looked at the weapon and sensed its chaotic energy. "This... does not belong to your world alone."
Captain America turned to him. "You seem to know a lot for someone new."
"I have seen power consume even the purest souls," Itachi said. "You must tread carefully."
Black Widow approached. "Who exactly are you, Itachi?"
He looked up at the gray sky. "A warrior who failed once, but won't again."
As the Quinjet took off, carrying the team back to base, Itachi sat alone near the rear window. Snowflakes danced against the glass. He closed his eyes briefly, allowing himself a moment of calm. In this world, he was no longer haunted by sickness or war. But the battle had only just begun.
And in his thoughts, the face of Sasuke lingered.
