Hyperdimension Gundam EX A

First Mission: Cosmic Compilier

Cover image: Extreme Gundam Leos Type floating in the space above Gamindustri with Gundam Legilis and Unicorn Gundam on the right and Gundam Epyon and 00 QAN[T] on the left. Leos, Zeheart, Banagher, Milliardo and Setsuna all standing in front of their respective Gundams.

Cosmic Compiler, an organization that studies mankind's history across the multiverse in the hopes of finding a solution to the declining population, has been gathering the data necessary for mankind's evolution, but Ex, the A.I that was given that task, has become corrupt and has lost faith in humanity as a whole, taking it upon himself to correct their mistakes, he travels through the dimensions, fighting and defeating many of their best pilots in his powerful machine, the Extreme Gundam. Cosmic Compiler sends Leos Alloy, one of their G-Divers and the pilot of the Extreme Gundam Leos type, to stop Ex and end his rampage. Ex's latest travels take him to Gamindustri, where Leos, on board the Valhalla battleship, tracks down the mad A.I.


On board the Valhalla, a young man with ash brown hair, wearing an ornate blue jacket with a gold trim, was reviewing the information that Cosmic Compiler had sent him regarding his newest destination. "Gamindustri… this unique place uses both technology and divine power to ensure prosperity, each major landmass has a corresponding goddess that protects and provides for its people, however, these goddesses are at war with one another." The G-Diver sighed; he didn't like the state of his destination one bit. "If they have the power to protect their people, why do they fight each other?" He thought to himself, he had it in his mind that anyone with that much power should be responsible enough to use it wisely.

Suddenly, female voice echoed in his head. "Leos Alloy…" The disembodied voice spoke with a sense of urgency.

Leos was shocked at the voice's sudden appearance "W-who said that?! How do you know my name?!" The G-Diver looked around but saw that nobody, save for the spherical robots that manned the ships controls. "I know it wasn't the Haros!"

"My name is Histoire, I am a tome, I am this world's everything and this world is my everything." The voice continued to echo in his head, this time sounding somewhat distressed. "I need your help… you and four more pilots must protect the goddesses."

Leos was shocked, his only objective in Gamindustri was to locate and capture Ex, the G-Diver was unsure of accepting Histoire's request. "Protect them from what? Each other?"

Histoire's continued to speak. "No, there is another threat that has recently appeared, his powers rival that of a goddess and he pilots a machine that looks just like yours."

Upon hearing Histoire's description of the new force that threatened Gamindustri, Leos knew immediately whom the tome was talking about. "Ex…"The G-Diver said, he remembered all the destruction the rogue A.I was causing. "So he is here…"

"Since he is from your world, I think you can stop him." Histoire said with a newfound sense of hope and determination in her voice. "And with the four heroes, you will save Gamindustri."

"Yeah, who are these heroes?" Leos asked, the G-Diver was very curious about Histoire's statement. "I've met many pilots during my recording missions that might fit that description."

Histoire continued to speak. "Four heroes to serve as guardians the inheritors of the four ancient heroes that helped stop the corrupted goddess of old, one for each of the current goddesses." The tome showed Leos the four landmasses of Gamindustri. "Zeheart Galette for Neptune, Banagher Links for Vert, Milliardo Peacecraft for Blanc and Setsuna F. Seiei for Noire." She let out a concerned sigh. "Neptune's guardian will have the most responsibility."

Leos recognized all of those names from the General Answer databank but one of them didn't seem to fit. "They're all great pilots but… Zeheart was killed shortly before the war ended and the failure of Project Eden… and from what I've studied, his mental state was heavily affected by the stress of becoming the Vagan leader and the guilt over losing his subordinates, are you sure giving him that kind of responsibility is a good idea?"

"I've observed him for a long time now." Histoire's voice continued, this time with a hint of sympathy in it. "He was always selfless and gentle and his loyalty knew no bounds, but his loyalty to his lord's cause conflicted with his gentle nature and in the end, he couldn't handle the burden of sacrificing so many people." The tome spoke with great sadness in her voice, the sad story of Zeheart's demise was affecting her emotionally.

"So, you're counting on his loyalty, is that it?" Leos raised an eyebrow, the G-Diver was very doubtful of Histoire's reasoning for choosing Zeheart. "What if he snaps again? And what makes you think he'll shift loyalties so easily?"

"Because I'm giving him a chance to redeem himself." Histoire's voice continued, this time with a hint of happiness in it. "To atone for his sins and pass on to the afterlife."

Leos was still a little confused, the G-Diver didn't really know what to make of Histoire's request, but he saw the opportunity that was presented to him. "If they can help me take down Ex, then fine, I'll help. I suppose we can use the Valhalla as our base of operations."

"So you'll help me?" Histoire replied in a grateful tome, the tome was happy that Leos had agreed to her request. "Wonderful, I shall transport the new heroes to us right away!"


The surroundings turned pitch black and four figures suddenly appeared before Leos, the first was a man with long white hair, tan skin and a red long coat, the second one was a man with short brown hair in a blue jacket, the third was a man with short messy black hair, wearing a short blue jacket, and the fourth was a tall man with long platinum blonde hair, wearing a long gray coat.

"Zeheart Galette, Banagher Links, Setsuna F. Seiei and Milliardo Peacecraft." Histoire spoke to the group, making her presence known to them.

"So…this is where you called me to?" Zeheart asked, still puzzled by the events that transpired.

"W-where am I?" Banagher asked in a panicked tone, this new environment still came as a shock to him. "Why did you drag me here!?"

"Is this my new mission?" Setsuna asked, he was sure that he had completed his final mission in his world.

"I expect answers." Milliardo said in an urgent tone, he wanted to know why Histoire had summoned him from his home world so abruptly.

"All four of you have a destiny in my world." Histoire told all four of the summoned heroes. "You, who carry the wills of the ancient heroes."

"I only agreed to your request so I can pass on to the afterlife." Zeheart responded in a sad tone, the word 'hero' was the last thing he wanted to be described as. "Don't give me a label I don't deserve…"

"I'm still trying to find out what's going on here." Banagher sighed; he didn't want to be in Gamindustri longer than he had to. "People need me in my world!"

"I have achieved communication with the ELS." Setsuna said, remembering the struggle he had to face in his world. "Is this new mission part of the dialogues Aeolia predicted?"

"You told me that the peace of your world rests in our hands." Milliardo said, he remembered the details of Histoire's request but he still had trouble understanding why he of all people was chosen. "But would you leave such a responsibility in hands stained with blood?"

"All your questions will be answered soon." Histoire reassured the summoned heroes, she was confident that they would help save Gamindustri from certain doom. "Soon, you will find your destinies, alongside your respective Goddesses."

"I'll have the data of your mobile suits scanned by our database and reverse engineered at our high speed molder." Leos said to his fellow Gundam pilots, he knew that if they were to face Ex, they would need their Gundams. "They'll be ready some time tomorrow."


Zeheart stood alone somewhere on the ship, staring at the moon over Gamindustri, the fallen Vagan leader reflected on everything that led him to where he is now with both a sense of guilt and bitterness in his heart. "I failed everyone... all those lives were lost for nothing." the Gundam Legilis Pilot blamed himself for the failure of Project Eden, feeling the weight of all the souls of the dead.

Zeheart closed his eyes for a moment, but when he opened them, he found himself standing on a sea of blood and staring straight at the fallen Vagan leader were the ghosts of all his fallen comrades. "Everyone..."

"The future and wishes of the Vagan Nation..." The ghost of a purple haired man with wine red eyes dressed in a yellow uniform with a black and light purple trim spoke to Zeheart with a stern look on his face, the dead soldier stared at the fallen Vagan leader. "all of them rested on your shoulders"

Zeheart stared at the apparition before him, wearing a guilty look on his face. "Dole..." The fallen Vagan leader felt that he let his subordinate's spirit down.

"The future you promised..." The ghost of a heavyset man with blue hair and matching blue eyes dressed in a green coat spoke out to Zeheart, wearing a fatherly expression.

Zeheart looked at the second apparition, still wearing his sad and guilty expression "Daz..." The fallen Vagan leader spoke the ghost's name with regret in his voice.

"Master Zeheart, I accepted death for the Eden you fought for." The ghost of a young man with blonde hair dressed in a grey uniform with a green cape hanging from his shoulders appeared before the fallen Vagan leader, urging him to remember his devotion his goals.

Zeheart saw the ghost of his wing man and most loyal subordinate. "Leil..." The fallen Vagan leader felt the full weight of sacrificing the life of someone that believed so much in his goals.

"What now, Zeheart?" The ghost of a man with long red hair, golden eyes dressed in a black and brown uniform with a dark purple top and a short violet cape appeared before the fallen Vagan leader, wearing a sinister smirk on his face. "Do you really think you can atone for all the people you failed by running away to this new world?"

Zeheart spoke the ghost of his late older half-brother. "Desil..." The fallen Vagan leader resigned himself to whatever insults the malevolent apparition had in store.

"Master Zeheart, I know that you'll reach your Eden." The ghost of a young woman with lilac hair and purple eyes dressed in a black dress-like uniform spoke fondly to the fallen Vagan leader, gazing at him with loving eyes.

Zeheart glanced at the ghost of his lost love, his voice now trembling with sadness. "Fram..." The Fallen Vagan leader reached out to the apparition.

With Fram's final smile, all the ghosts had vanished and a light dispelled the bloody abyss, coming from that light, Zeheart saw a twin braided woman with purple hair and blue eyes with strangely shaped pupils and irises dressed in a tight black bodysuit holding out her armoured hand to him.

As Zeheart took her hand, his vision ended and he found himself back on the Valhalla ship. "What was that..." The fallen Vagan leader was confused, the ghostly encounters were nothing new to him, but he had never seen the strange purple haired woman in any of his visions before.


At an unknown location in Gamindsutri, a man with short black hair, wearing a large white fur coat was standing in front of a black and white Gundam with glowing blue linings.

"A mix of both data and divine power." The black haired man smirked; the concept of divine power thrilled him. "Once I drain this world's data, that power will be mine! I, Ex, shall rule over all dimensions!" The rogue A.I laughed.


Author's notes: It's done, the first chapter of my newest story, I had to make some changes to the characters from Gundam EX A, so please bear with me on this, Mobile Suits will be integrated into the Neptunia universe in a similar fashion to my other story, The Warrior of Zero, however, since the technology is more advanced in the Neptunia universe, you'll see some unique mobile suits in upcoming chapters, The circumstances of the pilots being summoned will be revealed when the story reaches their respective landmasses, next chapter will reveal Zeheart's. Next chapter, Leos will brief the Gundam Pilots on their new mission and Zeheart will meet Neptune and Compa. Expected pairings will be Zeheart and Neptune/Purple Heart as well as IF, Banagher and Vert/Green Heart as well as Compa and Arfoire, Setsuna and Noire/Black Heart as well as 5pb and Milliardo Peacecraft and Blanc/White Heart. I hope you enjoy this story and check out HeeroUzuki's story, it was inspiration for this story and is much better than this one, you'll have a blast with it! Who should be paired with Nisa, Domon Kasshu or Graham Aker? Tell me in your reviews. Since Zeheart has no English VA at the moment, you can read his lines in Nero from Devil May Cry 4/ Lelouch from Code Geass's voice, it fits somehow. Happy Valentines everyone!
