Hello everyone, I am Rokettoman.

I came with another new crossover story. The story will be taking characters and elements from several mecha genre anime and games such as Gundam Seed, Code Geass, Iron Saga, and other mecha games and anime.

Some characters will likely become a little bit OOC than his or her canon counterpart.

I hope all of you readers will like it.

Edit: I edit several things for future chapters.

Disclaimer: I don't own Naruto and other media properties.


Chapter 1: Naruto the Immortal Wanderer.

Naruto Uzumaki, famously known as the number one knucklehead ninja, the most unpredictable ninja, the Jinchuriki of the nine-tailed fox, and then finally the hero of 4th great ninja war. After the war is over, as for their gratitude for his heroic deeds the Bijuus gives some of their chakras to Naruto, resulting in the power that he never wanted, immortality.

After several years Naruto finally became Hokage of the Hidden Leaf Village, married the person he loves Hinata Hyuuga, and have two strong children Boruto and Himawari. As the years' progressed, he felt his job as Hokage is already finished and slowly the people he cares one by one begin to leave him alone as they began to age and eventually dies, including his wife and his two children.

Naruto tries to pull himself from his sadness and sorrow. But thanks to his fellow immortal friend the nine-tailed fox, he slowly recovers from the grief and moved on. He chooses to leave Hidden Leave Village and live as a nomad. At the same time, there was a new kingdom founded on the island of Bardos (50 kilometers from the Land of Fire) called the Mycenae Empire. The new empire is famous for its scientific, technological, and mechanical research and discoveries. They manage to master the art of robotics, building giant machines called Talos to defend themselves against their enemies.

100 years after Naruto became a wanderer, the Mycenae Empire who was once a peaceful nation, declared war against the five great ninja nations. Under the command of the tyrant Ankoku Daishogun, and the almost invincible Talos units, they manage to obliterate almost all of the shinobi nations. But naruto appears once again and became an obstacle for Ankoku Daishogun to become the one ruler of the world.

The fight between two immortal warriors was fierce and lasted for almost 50 years. Their battles even take place in outer space. Felt their battle had gone on long enough, Ankoku Daishogun found a new way to end this for once and all, imprison him between two different worlds. Their final battle takes in the dimensions that are squeezed by two different worlds. Realizing that their fight will never reach an endgame and naruto is in a state of urgency, Kurama suggested using a last resort power that would threaten their immortality. Naruto agreed to it, declaring that the moment he become an immortal warrior, he knew the risks of his power and was prepared to die. Naruto took on a new form of Baryon Mode.

Kurama explained to Naruto that the form is like nuclear fusion, consuming all their respective energy and that he must be careful not to make any unnecessary movements or thoughts. The new form baffled Ankoku Daishogun with its sheer power. Naruto quickly began overwhelming Ankoku Daishogun. Soon after, the strain of Baryon Mode began catching up as Naruto began to tire. Kurama noted this form gradually drains all life forces, including Naruto's. However, it would also drain Ankoku Daisgogun's with each contact, meaning they just had to keep pressuring Ankoku Daishogun until his already diminished lifespan ran out.

After a fierce battle that lasted for quite a while, Naruto finally managed to imprison the weakened Ankoku Daishogun between two worlds, resulting in the amalgamation of the two worlds becoming one new expanded world; expanding its land and also the history. After Ankoku Daishogun's defeat, Kurama spoke with Naruto inside his subconscious revealing that Baryon mode proved too much to handle. Their lives are still saved by the gift of immortality, but Kurama's chakra power becomes weakened than before. Kurama warned Naruto that he would lose all access to Kurama's chakra and abilities if he use his chakra again, meaning that Kurama will lose his life. After that, Naruto becomes more careful and only uses his chakra when he fought an enemy. He doesn't want to lose his friend again after all.

1000 years after the destruction of the Mycenae Empire the alignment of two worlds into one, as he enters a small village in the Land of Earth, Naruto meets an orphan female child with long green hair and golden eyes. As he cannot abandon the child, Naruto decides to bring her into his odyssey.

She reveals her name as Cera, and as time goes by she became close to Naruto, really close, and sometimes it makes Naruto overwhelmed. Cera thinks that she will spend the rest of her life with Naruto, to be living happily ever after. But destiny says otherwise.

On Cera's 16th birthday, ten years after her destined encounter with Naruto, a great war once again happened between the old-type group who still use chakra and the new-type group who uses an advanced technology that developed from ancient Mycenae Empire transcripts that can even beat Chakra power.

Naruto joins the old-type group and leaves Cera alone back in the Yukigakure in The Land of Snow, one of the worst decisions he ever had. As the war goes on and the Old-Type group won various battles because of Naruto's services, one day his battalion group hears the news that the New-Type troops drop several nuclear bombs on the Old-Type's armory in Yukigakure and Otogakure.

Hearing this news, Naruto immediately leaves his battalion and went to Yukigakura as fast as possible. But after he arrives, Naruto is welcomed with the scene of ruins and burnt corpses of old people, women, and children. In grief he walks through the morbid scene to the house where he lives with Cera, only to find that the house is destroyed, and the flow of blood comes from the ruins of the house.

As he screams in agony, Naruto runs away, leaving the Yukigakure, leaving his comrades, leaving the war, leaving everything behind him. Without the help from Naruto, Old-Type began to lose every battle and then finally forced to surrender and submit to the New-Type group. The grieving Naruto who doesn't care about the outcome of the war chooses to leave and once again become a wanderer.

After centuries and millennia, new nations began to rise, the chakra power becomes obsolete as the new generation of humans finally forget and leave the chakra concept away. New generation peoples use advanced technology for fighting or for the war purposes like tanks, jets, and finally Mecha; a humanoid machine that was created based on the ancient data of Talos. People began to migrate to outer space and build several colonies. Some of the colonies even declared their independence from Earth.

The use of Mecha for combat vehicles makes Naruto, who has already recovered from his grieves, interested in having one of these objects. In the war known in history record as One Year War, Naruto meets and befriends new people like the crew of the White Base, the people of Saotome Getter Ray Institutes, and also people of the Photon Power Laboratory. He helps his new friends and joins in several wars with them after the One-Year War. Naruto also married a beautiful warrior named Marida Cruz, a formidable enemy turns lover.

After several years Naruto became brothers in arms with them, another tragedy happened. The bloodiest war ever known as the Moon Wars, the fight between humans and new terror that came from outer space known as Invaders; extraterrestrial creatures that were first known to exist on the planet mars decades ago. It is unknown where they came from, but likely related to the effects of the unification of the two worlds.

The swarms of Invaders in all shapes came from all directions and devoured all living things in front of it. Several space colonies are destroyed after their sudden attack and more than a thousand people die eaten by the Invaders. Not stopping with the colonies, the Invaders also targeted the colony on the moon and then the Earth.

Even with the combined power of chakra and technology, the Invaders are still proved as a tough enemy to handle. After several battles and causality through the wars, humanity finally won the war but with the cost that wounds Naruto's life once again. All of Naruto's friends and brothers in arms died in the final battle, including his wife who died protecting him, leaving Naruto alone once again in his immortality. In deep grief, Naruto decides that he's tired of the never-ending war and will never participate in any kind of war again.

But many years later he decides to join another war, and it would become his final war.


Present Time: 0190 NWC (New Western Calendar)

Moon Colony – Moon.

In the memorial of Moon Wars located in the moon colony, a man whose appearance only has minor change since the day he got the power of immortality Naruto Uzumaki, looked at the name of the fallen heroes listed on the monument. He's now wearing a black t-shirt covered with a long cream-colored trench coat; blue jeans and brown boots; and also the long red scarf made by his late first wife, Hinata Uzumaki, wrapped around his neck.

As he looked at the list of the fallen heroes' names, Naruto finally found the one that he searches for. "Hello again, dear..." Naruto said with a sad smile.

Then Naruto takes a white ocarina from his pocket, a gift, and a memento from his first wife when they're married. With the ocarina, Naruto plays a beautiful but also a sad melody. As the melody flows, a sudden nostalgic memory plays in his head like a movie. Every encounter and also farewells, every happiness and regrets, even after more than a thousand years, he still remembers it all.

After the song finished, he put back the ocarina in his pocket and then once again looked at the memorial. "I'm going to Earth soon. Don't worry, I will come here again in the future. See you later Marida, everyone..."

As he leaves the memorial monument, a green ball-shaped robot jumps from Naruto's bag.

"Naruto, Haro just got information from the hangar. Your new spaceship is ready to sail."

"Good, thank you for telling me, Haro."

"Finally! I can leave this no-gravity hell!" A voice belongs to one of Naruto's closest and oldest friends the nine-tailed Bijuu, Kurama. Naruto let a small laugh after hearing what Kurama said.

"You really miss the real air and soil, huh?"

"Of course, nothing beats real ground and soil!"

"Naruto, are you talking with Kurama again?" Haro asks. When Naruto talks with Kurama, in the eyes of the common man, Naruto looks like talking to himself. "Haro wants to talk to Kurama, can Haro say hello to him?"

"Piss off, Gumball!"

"He just said hello to you too, Haro."

As Naruto walks through the colony with Haro jumping around him, they finally arrive at the Moon Colony's hangar. In front of Naruto and Haro, a giant marigold colored spaceship that he just won from the lottery waiting for its master to cruise.

"Wow..., it's big..."

"Too big, too big."

"I don't think this is a spaceship for solo cruising, even though ironically it has 'Solo Ship' as its name."

What Kurama said was true, as Naruto and Haro enter the Solo Ship, the interior of the ship is so large it even had an artificial small garden inside.

"Yeah, maybe it used to be a spaceship for war or refugees," Naruto said as he looked at the ship's command control section.

"I hope we don't have any refugee ghosts here."

"Shush!"

Then he and Haro walk through the ship; checking the kitchen and all of the kitchen equipment are still functional; checking the many bedrooms and bathrooms of the ship and then finally checking the ship's hangar, "Oh, look who's already here."

Standing proudly in the Solo Ship's hangar, a giant robot colored predominantly in red and gold looks very dashing and mighty. The letters BF, which stands for Battle Force, the name of the group of brothers in arms when he joins to fight in Moon Wars, are inscribed on both its chest and forehead. Its main body is emblazoned in crimson, while highlights of white and blue jewels cover its arms and legs, with gold protrusions appearing on its shoulders and feet. The giant robot is created with the join forces of Saotome Institute and Photon Power Laboratory to create mecha that is compatible with Naruto and his almighty power, and its name is Compatible Kaiser!

"Looks old but still handsome and powerful." Kurama grins.

"Compati said he's ready for another adventure, Naruto," Haro said as if he understands what Compatible Kaiser desire.

"Is that so, Kaiser?" Naruto looked at Compatible Kaiser's face with a smirk. "Alright then, let's go back to our homeland, Earth!"

"Let's go! Let's go!"

"But first!"

"But first?"

"We need to clean the ship!"

"...Ugh, Haro is not a cleaning robot..."


As Naruto almost finished the ship cleaning with Haro, the television that he let on shows the latest news about what is happening on Earth's surface.

"Good evening, today the conflict between Holy Brittanian Empire and Earth Federation Government become more heated than before."

Naruto stopped the mopping as he hears the news.

Holy Britannian Empire is a kingdom that was formed one hundred years before the start of the NWE calendar in Harrison, Arkansas, by the 'people from old Earth'; one of them is Ricardo von Britannia who was an ancestor of the noble from the Mycenae Empire and then became their first emperor. At first, the Britannian Empire's territory covered only one-third of North America after various attempted coups and aggression against the United States. But after the destruction of the United States of America in the Moon Wars of 0089 NWE, Holy Britannian Empire succeeded in occupying all of North America's territory and land, and a year later it was de facto recognized by the Earth Federation as a legitimate and independent country.

In just several years, Holy Britannian Empire becomes one of the world's dominant military superpowers and started conquests in various nations. Now all of the nations in the American Continent are belong to Holy Britannian Empire. Britannian also creates and trademarked their own mecha system called Knightmare. The mecha unit is smaller than Mobile Suits but is faster and more agile than normal mass-produced MS. And unlike several mass-production Mobile Suits, Knightmare is also equipped with a functional eject button.

In these over one hundred years, Britannian Empire and Earth Federation Government always had some heated history on each other. Several small showdowns between two fractions also sometimes happened over the ownership rights of no man's land.

"There will be another war soon."

"Hmm..." That what Naruto's answer, he doesn't want to have anything to do with any kind of war again. He just wants to live peacefully as a wanderer and junk merchant.

Then Naruto finishes the ship cleaning and walks towards the ship's bridge. "Alright, the ship is all cleaned, and now say goodbye to Moon Colony."

As Naruto confirms his departure to the colony hangar staff via video call, the hangar gate is opened and Solo Ship begins to take off.

"Finally!"

"Goodbye! Goodbye!"

"This will be the mark of our new journey! Solo Ship, take off!"

*BEEP! BEEP BEEP!*

But when the Solo Ship is just leaving the Moon Colony's hangar, a loud siren can be heard from inside of the colony.

"What the?"

"Attention, Moon Colony residents! Six foreign objects, likely mobile suits, moving at full speed to the colony. All residents must evacuate to the protective chambers until the situation is safe! All troops and guards please gather at command room!"

It's too late for Solo Ship to come back to the colony as the hangar gate is closed and locked.

"...Just my luck..."

The six foreign objects move closer to the moon colony and finally, Naruto can take a look at what object that causing the ruckus. Naruto recognizes the five of the mobile suits; EMS-VSX3 Tortuga, two EMS-07 Erebado, and two EMS-06 Batalla. Those fives mobile suits are created by the Jupiter Empire, one of the colonies near planet Jupiter that declared their own independence after the One-Year War.

But what intrigued Naruto most is the sixth mobile suit.

"Isn't that... a Gundam?"

The sixth mobile suit is a bright red mobile suit that resembles Gundam, a powerful mobile suit that one of Naruto's friends use back in the One-Year War to Moon Wars. From what can be seen, the red Gundam is probably the enemy of the other five MS as they shoot the red Gundam without giving it any chance to strike back.

"Oi, oi, five against one? That's not fair."

The red mobile suit can only evade the barrages of laser and bullet shoot. But some of the shots from the Jupiter Empire's MS hits the Moon Colony's surface. Destroying several sections of the colony.

"Shit, if we let this goes on the Colony would be destroyed! Haro, take control of the Solo Ship! I will go out there and give them lessons!"

"Aye-aye, Naruto!"

"Alright! Just like old times!"

"We're going to need your power again, Kaiser!"

As Naruto arrived at the hangar, more than ten Seagull-type Fighters appeared from Moon Colony and engaged in combat against the Jupiter Empire's MS.

"Don't interrupt us, Earthlings!" A sound of a middle-aged man can be heard from inside the Tortuga as he and other Jupiter MS turns their attacks on the Seagull Fighter's troops. In just several minutes, the five Jupiter MS easily eradicates all of the Seagull Fighters with unavoidable beam shots.

"Stop! What are you doing!? Why you attack them!?" A sound of young females can be heard inside the red Gundam, angered and frustrated. "They're just innocent people!"

"That's your own fault, traitor!" The pilot of Tortuga said, "Look! Because of your betrayal, you forced us to kill the Earthlings that had anything to do with Jupiter Empire's business!"

"That doesn't have anything to do with my betrayal!"

"Shut up and die!"

"HEY, YOU PRICKS!"

A sudden shout makes the five Jupiter MS and the red Gundam turns their head to the solo ship. Now standing in the top of the Solo Ship, a giant robot named Compatible Kaiser standing menacingly. The red Gundam and the five Jupiter MS feel intimidated with the appearance of Compatible Kaiser.

"Wha-what is that?"

"A giant?"

"T-that doesn't look like Mobile Suit or Knightmare..."

The Jupiter MS pilots murmuring to each other.

The pilot of the red Gundam widened her eyes, "Isn't that... Super Robot?"

"You better stop your little showdown or I'm gonna plummet all of you into scraps!" Naruto on the cockpit of Compatible Kaiser warns all of the Jupiter MS.

The veins of Tortuga's pilot are almost popped, "Grrr, we're not going to obey to a mere Earthlings! Everyone, that robot had a huge figure than our MS and we can use that as our advantage!"

"You're right captain, the bigger the body of the robot is, the hitbox must be bigger too!"

"DESTROY THAT GIANT ROBOT!"

"Sigh..." Naruto responds with a sigh as the five Jupiter MS began to shots several beam blasters at Compatible Kaiser. "HOWL! COMPATIBLE KAISER!"

The eyes of the Compatible Kaiser shine brightly as it began to move and evades the barrages of beam shots with unbelievable speed.

"WHAT!?" All of the Jupiter MS pilots shout in unison. "I-It can't be..."

"Naruto! Gave them something that they will remember forever!"

"Alright then! SPIRAL KNUCKLE!"

Compatible Kaiser charges its left arms and then launches the hand in a spinning attack, directed at one of the Batalia.

"RR-R-ROCKET PUNCH!? GUAKH-" The spinning fist and destroy the Batalia immediately.

"I-Impossible..." The pilot of the Tortuga stuttered that one of his lackeys is killed instantly in front of his eyes.

"UWAA! YOU DEMON!" Two Erebado recklessly charge at Compatible Kaiser while shooting their beam machine guns.

Compatible Kaiser easily evades the barrages of the beams and the claw attack from the Erebados.

"Hmm, I think this is enough," Naruto says with a grin. "OVER BEAM!"

As the crown jewel of the Kaiser's forehead glowing, a fast-moving beam suddenly fired from it. destroying the two Erebados instantly without any traces.

"GUUAKKKHHH!"

"No..., even our newest Erebado..." The pilot of the last Batalia said in disbelief.

"...Wow..." The pilot of the red Gundam is said in awe.

Compatible Kaiser looked at the remains of Jupiter MS and menacingly pointed its finger at Tortuga. "Leave, or I will give you another surprised."

The pilot of the Tortuga gritted his teeth, "This is not going to be the last time you saw us, monster!" Then Tortuga and the last Batalia leave immediately, returning to their base.

"Huff," Naruto relaxed his body. "It's been a while."

"Yeah, and Compati Kaiser is still a reliable partner for us. Even over one century without action."

"Hahaha, you're right," Naruto said with chuckles, and suddenly he got a request call via radio communication. Naruto touches the answer button, "Is this the red Gundam pilot?"

"You know about Gundam too?" The surprised sound of the pilot can be heard. "I... I want to thank you for your help."

Naruto whistled softly. It's been a while for Naruto to meet a woman pilot who piloting an SSS unit mecha. The last time was his late wife. "You're welcome, why they're chasing you by the way?"

"For that, can we talk about that in your ship?"

Naruto paused for a moment, and then he nodded his head. "Alright, follow me. Haro, open the hatch."

"Okay!" Haro's sound can be heard via the communication link.

Compatible Kaiser enters the Solo Ship first, followed by the red Gundam behind. After they safely landed, Naruto exit the Compatible Kaiser's cockpit and was welcomed by Haro that jumped at him.

"Welcome back Naruto!" Haro said as Naruto catch the jumping Haro while chuckling.

"I'm back."

Then Naruto and Haro wait for the red Gundam pilot to come out from her MS. As the cockpit door opened, a figure of a slender young woman wearing the normal MS pilot plus the helmet comes out from the cockpit. Then the pilot release her helmet, reveals a young beautiful woman with long pink hair and blue eyes.

"...wow..." Naruto is astonished by the beauty of that young woman.

Then the red Gundam pilot began to speak.

"My name is Lacus Clyne. and Earth..., is in great danger."

It seems wherever Naruto goes, war is always coming back and haunting him again.


Somewhere in Holy Britannian Empire, Earth.

A young girl with long green hair and white skin completely bound and gagged in a straightjacket and other restraints all over her body inside a small containment.

Her eyes are closed as she likely sleep, but in her mind, he repeats the name of the only person he really loves in this rotten world.

"Naruto..."


Naruto's attire is based on Ryoma Nagare from Getter Robo Armageddon, and several of his traits are inspired by Gai Kurenai (Ultraman Orb.)

And Lacus's pilot suit is just like Lunamaria's pilot suit.
