I don't own Percy jocks on or Naruto.

Chapter 1: The Hidden Siblings

Camp Half-Blood was buzzing with activity as demigods from all corners of the world trained, played games, and forged alliances. Percy Jackson, the hero of the prophecy, was busy with his swordplay when a strange disturbance in the air caught his attention. He glanced at the sky, sensing an unusual energy, and a figure dropped from the heavens with a resounding thud.

The newcomer was none other than Naruto Uzumaki, the famous ninja from the Hidden Leaf Village. He stood there, clad in orange and black, with a confident grin on his face. His presence stirred both curiosity and apprehension among the campers.

"What's going on here?" Percy asked, stepping forward with Annabeth and Grover at his side.

Naruto chuckled, scratching the back of his head. "Sorry for the entrance, folks. I got a little carried away. The name's Naruto Uzumaki, and I'm a ninja from another world."

Percy raised an eyebrow. "Another world? Like, a parallel universe?"

Naruto nodded. "Exactly! I come from a world filled with ninja, jutsu, and some really crazy adventures."

As the two demigods exchanged introductions, a powerful energy radiated from Naruto, making Percy feel an odd connection to him. It was as if they shared a cosmic bond. Before Percy could question this further, Naruto dropped a bombshell.

"Oh, and did I mention? I'm the brother of Cronus."

Percy's eyes widened in disbelief. "Cronus? The Titan of Time? That Cronus?"

Naruto nodded solemnly. "The same one. Our mother is Gaea, and our father is Uranus. I'm the firstborn of the Titans."

The revelation sent shockwaves through Camp Half-Blood. The Titans were ancient, powerful beings who had been defeated by the Olympian gods eons ago. Percy couldn't fathom what it meant to have the brother of one of the most dangerous Titans in their midst.

"Wait, if you're Cronus's brother, does that mean you're here to cause trouble?" Annabeth asked cautiously.

Naruto shook his head. "No way! I've got my own reasons for being here, but causing chaos isn't one of them. In fact, I'm here to help."

Percy exchanged a glance with his friends. They had faced countless threats over the years, but a Titan's brother was something they hadn't prepared for.
