The Arrival of Naruto in the Marvel Universe

Charles exclaimed "Not good!" and quickly backed away.

Thena's hands transformed into divine weapons, and she spun around, swinging a spear at Gilgamesh.

"Boom!"

The sudden turn of events shocked Gilgamesh. He quickly conjured a golden arm guard to block the attack, but it still pushed him back a step.

Thena, her pupils now white, glared at Gilgamesh and shouted, "Everyone in Centuri Six will die!"

Gilgamesh, seeing Charles behind Thena, called out, "Run!"

He then tried to calm Thena, softly calling her name, "Thena!"

"It's too late, we can't save them," she replied.

"Thena?"

Ignoring his words, Thena transformed her spear into a cascade of stars and lunged at him.

The two began to battle intensely, with Thena attacking relentlessly while Gilgamesh remained on the defensive, hoping to use his power to wake her from her trance.

As they fought, the surrounding area was destroyed. Charles realized why the land was so barren. Every time Thena had an episode of Mahd Wy'ry, she and Gilgamesh fought, leaving the area in ruins. It was a miracle the lone tree had survived.

Suddenly, Gilgamesh was sent flying by one of Thena's sweeping attacks. With her initial target gone, Thena turned her attention to Charles and charged at him.

As Thena rushed towards him, Charles pondered whether the Mangekyō Sharingan's genjutsu could suppress her chaotic memories and wake her up.

Unlike others, Charles understood Mahd Wy'ry. It was a manifestation of Thena's old memories from her missions, which randomly surfaced and caused her current memories to become confused, prompting her to attack everything around her.

But he planned to use the Mangekyō Sharingan's power as a last resort to awaken Thena. For now, he wanted to test his skills against her.

Charles suddenly drew a ninja blade, forged from vibranium.

"Come on!"

"Clang! Clang! Clang!"

He expertly parried Thena's attacks with his blade, creating a flurry of sparks.

In a swift movement, Charles distanced himself from Thena. He flexed his arm and muttered, "She's quite strong."

In the next instant, he used the Body Flicker Technique to reappear in front of Thena, his blade now glowing with blue light from the wind chakra infused into it.

"White Fang Technique, First Form!"

A massive blue blade of energy shot out towards Thena.

"Boom!"

The ground beneath Charles's feet shattered from the force of his attack, kicking up a cloud of dust.

Just as the attack was about to hit, Thena's divine weapons transformed into a shield, blocking the strike. The force of the attack pushed her back, but she remained standing, her eyes locked onto Charles.

Thena's shield dissipated, and she readied her weapons for another assault. Charles braced himself, knowing the battle was far from over.

Charles's weapon clashed with Thena's divine armament, blocking the strike.

"White Fang Sword Technique, Second Form!"

"White Fang Sword Technique, Third Form!"

Charles's attacks grew more ferocious, his chakra-infused blade sending arcs of energy that eventually sent Thena flying. She rolled across the ground, her divine weapons dissipating into starlight, and her white dress now covered in dust.

Gilgamesh, arriving on the scene, was stunned. When did Earth have someone this powerful? Was this guy really from Earth?

While Gilgamesh was processing this, Thena steadied herself and her attire changed into the armor of the Eternals, her white dress vanishing.

"Whoosh!"

Thena charged at Charles with incredible speed, attacking him again with even greater ferocity, her hands now transforming into dual long swords.

"Slash! Slash! Slash!"

Thena's attacks were relentless and fast. Charles did his best to parry with his ninja blade, but one sword managed to break through his defense, aiming for his abdomen.

"Boom!"

Instead of being impaled, Charles was sent flying, his Merlin robe absorbing the blow. He skidded to a halt, creating deep furrows in the ground.

Charles glanced at his blade, acknowledging that his swordsmanship was still inferior to Thena, a warrior with thousands of years of combat experience.

He made his blade disappear and looked at Thena.

"Round one is over. Now, round two begins."

Charles formed hand seals quickly. "Water Style: Exploding Water Colliding Wave!"

Despite being in a dry area, a massive wave of water materialized, surging towards Thena like a tidal wave.

"Boom! Boom! Boom!"

The colossal wave, reaching dozens of meters high, crashed down. Gilgamesh, seeing this, was in disbelief. "Is this guy also an elemental mage? Damn, I can't fly!"

Thena faced the incoming wave without fear, her divine weapon enlarging as she slashed into the water.

Gilgamesh also conjured a divine arm to punch the wave.

"Boom!"

With a combined effort, Thena's slash and Gilgamesh's punch shattered Charles's water attack. Charles wasn't surprised—this was the true power of the Eternals.

He thought about Thanos, another Eternal, and found the display of power unsurprising.

Gilgamesh called out to Charles, "Hold Thena off, I'll wake her up."

Charles shook his head. "I want to spar with Thena a bit more."

Gilgamesh shouted, "Friend, now's not the time for sparring. Your life is at risk!"

As an Eternal, Gilgamesh knew both he and Thena had high magic resistance. But despite his warning, Charles was determined.

Charles faced Thena's onslaught with confidence. Thena conjured a longbow and unleashed a barrage of arrows.

"Swish! Swish! Swish!"

The arrows flew like meteors towards Charles. Instead of blocking, he used the Body Flicker Technique to evade and counterattacked with a jutsu.

"Ice Release: Ice Pillar Swallow!"

Thena's shield materialized to block the ice projectiles, but they turned into a freezing mist, encasing her in ice. Charles remained cautious, watching as Thena shattered the ice prison, scattering shards everywhere.

"Wood Release: Four-Pillar Prison Technique!"

Wooden pillars rose from the ground, trapping Thena in a sturdy wooden cell. Charles's Wood Release was stronger than Yamato's, with the wood being harder than steel and possessing sealing properties.

However, two golden flashes from within cut through the wood effortlessly.

"Boom!"

Thena burst free, her spear enlarging as she thrust it at Charles's position, shattering a wooden substitution.

"Rasengan!"

Charles appeared behind Thena, striking her back with a Rasengan. The impact sent her flying but didn't cause significant damage.

Charles was frustrated by Thena's high defense and resistance. If this was her level, the superhuman Eternals would be even tougher. But he had more techniques to try.

Gilgamesh approached, calling out, "Hey, if you really want to spar, let me wake Thena up first, and then I'll fight you."

"Alright, let's end this then."

"Sharingan: Mangekyō, activate!"

Charles activated his Mangekyō Sharingan and cast Tsukuyomi, trapping Thena in a genjutsu. Within the illusion, he suppressed her chaotic memories.

"Thena!"

At his call, Thena's eyes cleared, and she saw a massive blood moon above. Confused, she asked, "Where is this?"

"This is the Tsukuyomi realm, a world I created with my genjutsu."

Thena looked at him in amazement, "You woke me up?"

"Yes, you fell into a frenzy. After sparring for a while, I decided to use my abilities to calm you down."

Thena stared at Charles with growing curiosity. This man not only fought her when she was in the state of Mahd Wy'ry but also managed to wake her up. It was truly remarkable.

"Thank you!"

Charles smiled. "It's nothing. Seeing you in that state, I felt it was necessary to help you find yourself again."

"Shall we stay here for a while or end the illusion now?" Charles asked. "In this space, 72 hours will pass, but in the real world, it'll only be a moment."

Thena's eyes lit up at his words, and she replied, "Let's stay here a bit longer. I'm very curious about you and have many things to talk about."

Charles agreed, "Alright."

The two began conversing in the Tsukuyomi realm, sharing their stories and learning from each other. Charles had many questions about Thena and her past, while Thena was equally interested in Charles's abilities and background.

They spent a significant amount of time in the illusionary space, but to Gilgamesh outside, it was just an instant.

In the blink of an eye, Thena's eyes cleared, and she dismissed her weapons.

Gilgamesh looked at Charles in amazement and said, "Oh my God, how did you do that? Are you an Eternal too?"

"Only an Eternal can wake another Eternal from Mahd Wy'ry. How did you manage it?"

Charles smiled. "You've misunderstood. I'm not an Eternal."

Thena walked over and hugged Charles. "Thank you, Charles."

Charles hugged her back, gently patting her shoulder. "It's alright. It's over now. You don't have to worry about Mahd Wy'ry for a while."

Gilgamesh, still confused, asked, "What happened?"

In the Tsukuyomi realm, Charles had used his illusion to strengthen the seal on Thena's chaotic memories. Unless triggered by extreme stress or emotions, Thena wouldn't experience Mahd Wy'ry in the short term.

After they separated, Thena introduced Charles to Gilgamesh. "Gilgamesh, this is my new friend, Charles. He has temporarily resolved my Mahd Wy'ry issue."

Gilgamesh's eyes widened in astonishment. "Really?"

Charles nodded. "Yes, temporarily. It's not a permanent cure."

Gilgamesh beamed. "That's amazing! We should definitely celebrate."

He looked back at their house, grateful it had not been damaged in the fight. "Charles, let me treat you to some of my cooking. I've learned recipes and brewing techniques from Odin himself. Do you know the All-Father?"

Charles nodded. "Yes, I recently returned from Asgard."

Gilgamesh clapped his hands. "Perfect! Let's go then."

The three of them headed to the house, ready to enjoy a well-deserved feast and celebrate their new friendship.
