Disclaimer: I do not own Naruto, nor Dragon Ball Z. This is a crossover story that takes place during the History of Trunks.
"Sasuke Uchiha is a man on a mission. A mission to locate all of Kaguya's Dimension and discover the reason on why Kaguya Otsutsuki had created an army of White Zetsu. He was to uncover her secrets and report it back to Hokage, Naruto Uzumaki."
"This doesn't look like Kaguya's Dimension." A one-armed adult Sasuke Uchiha with a black stated as he had stood in an abandoned street of a city called Pepper Town. There were large skyscraper buildings destroyed and abandoned all around him. Destroyed automobiles in the road. Not a single person was in sight. It was pure chaos. Sasuke had assumed this was one of Kaguya's Dimension at first, but realized as he looked at a floating red automobile, this couldn't be one of her Dimensions.
"Where... the hell am I?" Sasuke muttered to himself, then had suddenly sensed a strong energy coming from three o' clock. 'What is this presence I'm feeling? Is it one of the Otsutsuki?' Sasuke then looked up toward the sky as he could feel the strong energy coming his way. He used his right arm to lift his hair up that was hiding his Rinnegan from people and looked closely at the person who was coming his way at a fast pace. As Sasuke Uchiha had observed, he saw a man dressed in an orange Gi, blue armbands, a blue sash and blue boots flying across the blue sky toward the direction he was in. The man in the orange Gi had one arm and his hair was blonde. This man was Son Gohan.
Son Gohan did not pay attention to Sasuke Uchiha as he was too focused on the Androids such as Seventeen and Eighteen. He continued to fly toward their destination.
Sasuke narrowed his eyes after seeing Son Gohan fly across the sky. 'I think I'll follow that guy. He might have the answers that I'm looking for.' Sasuke thought as he had also decided to follow the direction that Son Gohan had flown toward. But by foot.
"A few minutes pass and Sasuke Uchiha decides to follow the half-Saiyan on foot."
Adult Son Gohan had approached the Androids-technically cyborgs known as Android Seventeen and Android Eighteen. Gohan had recently damaged Android Seventeen's wardrobe by kicking him toward a building. Son Gohan had stood and was prepared to fight the pair of Androids to the death. The last time he fought the Androids, he had previously lost his entire left arm and gained a scar across his face.
Android Seventeen and Eighteen had stood side by side, miles before Son Gohan.
"Gohan? You're still alive?" Android Seventeen asked as he smirked at Son Gohan.
Son Gohan had frowned.
"We'll fix that, soon enough." Android Eighteen gave Gohan a cruel smile. "Let's kill him. Full power."
"First one to kill him wins. Sudden death." Android Seventeen said.
"You said exactly what I was about to say." Android Eighteen said as she took one step forward with her left foot.
"Tch!" Son Gohan had grunted as he saw both Android Seventeen and Eighteen slowly approach him. "There's no way that I'm gonna die! And even if my body breaks, someone stronger will take my place... to dismantle you heartless androids!"
Android Seventeen had chuckled. "We'll see about that."
Son Gohan had taking a fighting martial arts stance-similar as Son Goku's. He was ready to fight to the death against the Androids. He watched the Androids quickly fly towards him. Gohan had generated a blue ball of Ki into his right hand. As he was waiting for the Androids to approach him in close range...
'Fire Style! Fireball Jutsu!'
A massive fireball had suddenly appeared from nowhere and it was aimed toward the pair of Androids. Android Seventeen and Eighteen quickly dodged the fireball by jumping a few yards back from it. The massive fireball hitting the ground. Causing a smokescreen big enough to hide Gohan's body.
"Now what?" Android Seventeen asked after he had dodged the fireball made from chakra.
A few seconds have passed and suddenly. The Androids heard another masculine voice unfamiliar to them. "I see two heartless people trying to murder a one-armed man. That doesn't seem fair at all."
"What?" Android Eighteen asked.
As the smoke had cleared, an adult Sasuke Uchiha had stood a few yards in front of Son Gohan. Staring directly at the Androids. His Sharingan was unactivated, while his Rinnegan was.
"Another one?" Android Seventeen asked himself as he and Android Eighteen laid their cold blue eyes onto Sasuke Uchiha.
"I appreciate the help, but... who are you?" Son Gohan asked Sasuke.
"Don't worry." Sasuke slightly turned his right face toward Son Gohan. "I may not know what's going on right now... but I'll get the answers I need when this is over."
There will be a Part 2.
