Reborn as Jon Snow with God System

Jon Snow stood firm in the center of the vast training dimension, his mind focused and calm. He had never been more prepared, not even for the wars he had faced in the past. His body, now enhanced by the strength and vitality of Hashirama Senju, had long ago surpassed its mortal limits. His senses were sharper than any normal man's, his chakra reserves as vast as the ocean, and his magical abilities , honed through years of training and mastery. He had learned every technique from the world of Naruto, and more. Now, with all the knowledge he had gained, he was ready to face the one creature capable of challenging him: Ghidorah.

Ghidorah, his three-headed dragon son, stood before him, an awe-inspiring titan of immense power. Standing 60 meters tall, with scales as dark as the night sky and three massive heads, each crowned with glowing eyes of crimson fire, the dragon exuded raw, primal strength. His wings stretched out like the shadow of a storm, darkening the sky around them. Jon had known this day would come, the day when his dragon would become so powerful that he would have to face him in battle, to see how much his son had grown.

With a deep breath, Jon focused his chakra and magical energy into his core. He had been through battles before, but this was different—Ghidorah was not an enemy. He was his son, his gift, his companion. Still, Jon had never been pushed to go all out before. It was time to see how far his dragon had come, and whether his power matched the strength of the legendary dragons he had known of in his past live in shows.

"Show me your power, Ghidorah," Jon said softly, but his voice echoed across the vast dimension, reaching the ears of the mighty beast. Ghidorah tilted his three heads in unison, as if understanding the challenge. Then, with a roar that sent shockwaves through the air, he charged at Jon with terrifying speed.

Jon wasn't surprised. Ghidorah's massive form lunged forward, his wings slicing through the air like daggers. Each head hissed with anticipation, and Jon could feel the primal fury of the creature as it bore down on him. The dragon opened its mouths, preparing to unleash its devastating gravity beam.

Jon raised his hand and slammed it onto the ground, activating his Wood Style—**Mokuton: Jukai Kōtan (Wood Style: Advent of the World's Tree)**. Instantly, enormous trees erupted from the ground, their trunks massive and sturdy, rising high into the air like an impenetrable forest. The trees twisted and formed a protective barrier around Jon, their wooden branches spreading wide, like arms that could shield him from any attack.

Ghidorah's gravity beam crashed into the barrier, the force of the beam tearing through the trees and causing them to shake violently. The shield cracked but held strong. Jon's eyes narrowed in concentration. His dragon's power was immense, but he could already tell that this battle would test them both.

Jon moved quickly, his body agile despite his immense size. With a flick of his wrist, he activated **Katon: Gōkakyū no Jutsu (Fire Style: Great Fireball Technique)**, a massive torrent of fire erupting from his mouth and roaring toward Ghidorah's middle head. Ghidorah's head recoiled from the heat, but he retaliated instantly. One of his other heads opened its maw and unleashed a blast of ice from its throat, a chilling Hiryū no Kōri (Ice Dragon's Breath) that collided with Jon's fire. The two elements clashed violently, creating a massive explosion of steam and smoke that shrouded the battlefield.

Jon didn't hesitate. He had already used the elemental styles he had mastered—fire —but this wasn't enough. Ghidorah was a formidable opponent, and Jon knew he would have to push himself beyond his limits. He summoned his chakra and focused, the symbols of **Fūinjutsu (Sealing Techniques)** glowing on his palms.

Jon activated **Fūinjutsu: Kin (Sealing Technique: Chains of the Great Barrier)**, summoning massive, ethereal chains that shot from the ground and wrapped around Ghidorah's limbs, attempting to bind him in place. The dragon roared in fury, struggling against the chains, his three heads snapping and thrashing in every direction. The chains pulsed with chakra, trying to subdue the great beast, but Ghidorah was no mere animal. His power was beyond what Jon had anticipated.

One of Ghidorah's heads lifted, his eyes glowing brighter as he summoned the **Gravity Beam** again. The beam hit the chains, causing them to shatter under the immense force of the gravity manipulation. Jon jumped backward, avoiding the blast by mere inches as the beam gouged the ground, creating a massive crater where he had stood just moments before.

Jon's brow furrowed. Ghidorah wasn't going down easily, and neither was he. He wasn't just the body of Hashirama Senju—he had access to the most powerful techniques in the world. He decided it was time to use one of his more advanced jutsu.

Jon began weaving hand signs, his movements swift and precise. He activated **Kuchiyose no Jutsu (Summoning Technique)** and slammed his palm onto the ground, summoning the ancient,—an enormous, spectral tree that could manipulate the very fabric of the earth.

The massive beast, an extension of Jon's power, appeared behind him, its roots extending far and wide, splitting the land and creating a massive barrier around them. Its presence pushed against the atmosphere, distorting the space around them. Ghidorah shrieked in anger as it tried to break through the barrier. Jon was ready.

He leapt into the air with his Wood Style **Tsuchi no Jutsu (Earth Style)**—forming a massive **Doton: Doryū Jōheki (Earth Style: Mud Wall)** in front of him to block Ghidorah's next attack. The dragon unleashed another blast of ice from one head while another head fired its gravity beam, both forces colliding with the earthen wall Jon had summoned. The sheer force of the attack sent Jon hurtling backward, his feet scraping the ground, but he dug in, refusing to relent.

He then channeled all of his chakra into one final attack. **Raiton: Raikiri (Lightning Style: Lightning Cutter)**—a deadly, high-voltage technique that he had perfected over years of training. The surge of lightning crackled through the air, arcing toward Ghidorah with blinding speed. The dragon's middle head opened its maw to retaliate, preparing another gravity beam, but Jon wasn't done. He unleashed **Katon: Karyū Endan (Fire Style: Fire Dragon Flame Bullet)**—an enormous fireball that surged towards Ghidorah's side.

The lightning and fire collided, creating a cataclysmic explosion that sent shockwaves throughout the dimension. Jon stood his ground, the heat of the explosion not even affecting him as he surrounded himself with an armor of **Raiton: Kaminari no Yoroi (Lightning Style: Thunder God's Armor)**, a defensive technique that shielded him from the blast.

As the dust and smoke settled, Jon looked at his dragon. Ghidorah, though scorched and battered, still stood tall. His three heads, though tired, were filled with fury and pride. Jon knew that his son had grown far beyond what he had ever imagined. This battle, though fierce, had strengthened their bond.

Jon breathed heavily, his body covered in sweat. He wasn't tired, but he could feel the weight of the battle. Ghidorah's immense power had tested his limits, but he had learned something important: they were far more than just master and servant, or even father and son. They were equals in power, equals in will, and they would face the world together.

"You've grown strong, Ghidorah," Jon said, his voice filled with respect.

The three-headed dragon bowed its heads toward Jon, a sign of loyalty and mutual understanding.

"Now, let's go,"
