Hello there guys, Warmachine375 here. I have made another Gundam crossover story called "As Big As A Battleship, Puru!" and I based it from "As Big as a Battleship" Self Insert crossover story between Gundam UC and Battletech from Spacebattles Forum which was unfortunately cancelled by the author who made another Gundam UC x Battletech Self-Insert crossover story called "Mobile BattleMech Orion AD 2766: Kerenskys Counterattack".

Of course, I'm going to make this one different to stand out on its own.

Oneshot just in case.

Synopsis: "Taking part of testing out an experimental hyperdrive system for Axis Zeon, Ple Twelve finds herself alone in the Post-Disaster world and she only has the Psycho Big Zam at her side. Then she decided to take her Mobile Armor for a walk with some new friends she made. A very enthusiastic walk, puru!"

Disclaimer: I do not own Gundam UC and Gundam Iron Blooded Orphans series. They both belong to Sunrise and Yoshiyuki Tomino.

Enjoy and don't forget to review. :D


Chapter 1

Somewhere in the Asteroid System, the Axis, UC Universe

"All systems green. Psycho Big Zam is ready for launch, puru."

A ten year old orange haired girl in her red pilot suit and helmet declared as she was sitting on one of the three pilot seats of the Big Zam's cockpit block: a pilot, a radar operator, and a gunner; though it can be operated by a single pilot with the assistance of computers. Of course, she took the pilot's seat at the center and her white and violet Mobile Armor was outfitted with the Psycommu System which would allow her to control it as a Cyber Newtype.

The MA-13 Psycho Big Zam, the Prototype Cyber Newtype-use Anti-Fortress Heavy Assault Space Mobile Armor.

It was developed by Neo Zeon at some point after the One Year War ended and the Zeon loyalists had fled to Axis, refusing to surrender to the Earth Federation in defiance. This Mobile Armor was supposed to be the second Big Zam unit produced at A Baoa Qu for the hypothetical company of Big Zams that was planned to be used against Jaburo as Vice-Admiral Dozle Zabi once bragged, "Once the Big Zam goes into mass production, it'll be the end of the Federation!"

Unfortunately, Dozle Zabi perished at the Battle of Solomon where the original Big Zam was destroyed by Amuro Ray in his RX-78-2 Gundam with the aid and heroic sacrifice of Sleggar Law in his G-Fighter, ending the Zeon resistance in Solomon.

After the One Year War, the second Big Zam unit was taken by the Zeon loyalists during their exodus to Axis, refusing to allow the Federation to get their hands on the Mobile Armor. During the rebuilding and reorganization of their military strength, the Neo Zeon had modified the second unit to not only have a Psycommu System along with 12 Funnels and 11 Bits stored inside several hangars across the body, it also have a Minovsky Craft System for propulsion and two extra Minovsky Ultracompact Fusion Reactors as backup generators which remain dormant until emergency use.

Along with its two massive legs that can bend and fold to provide extra rocket thrust.

And it's piloted by a 1 Cyber Newtype pilot.

"Confirmed, all systems of the Mobile Armor are green. You're good to go, Ensign Audrey Burne.", someone at the mission control from the Axis.

But that's not really my name. I'm Ple Twelve, puru!, she thought as she checked through the controls of the Psycho Big Zam with everything labeled on it. That also includes the I-Field switch, which had a very small warning on it about potentially making the fusion reactors overheat if it was left on for too long.

Ple Twelve was one of the several clones of Elpeo Ple, a powerful Newtype girl, created by Glemy Toto who conspired to usurp the leadership of New Zeon from Haman Karn who currently served as regent of the young Mineva Lao Zabi whom she used as a figurehead and someone to rally the Zeon loyalists to Axis. Of course it took him some years to properly grow and develop the Ples in their pods while ensuring their existence remained a secret underneath Haman's nose.

By the time they're finished, Glemy then put the Ples under cold sleep in the storage unit of the Sandra, keeping them in reserve until he chooses to release one or two of them if he had uses for them or on a whim as he pleases. As such, Ple Twelve had the "honor" of piloting the Psycho Big Zam and whether or not she lives or dies, the blonde ambitious Neo Zeon officer can just get another Ple to replace her in her stead.

And now I'm testing out an experimental hyperdrive for Neo Zeon which may or may not probably work. But orders are orders and good soldiers follow orders, puru!, Ple Twelve thought with a casual shrug as she began to activate the Psycho Big Zam with the controls on the console.

The Hyperdrive Generator was an experimental propulsion device made by an ambitious Neo Zeon scientist named George Walton which could theoretically allow a spaceship to reach lightspeed and traverse the void between stars in the alternate dimension of hyperspace. It functioned by gathering the concentrated amounts of Minovsky Particles into the ship's engines before activating it to hurl a ship into hyperspace while preserving the vessel's mass/energy profile.

It would grant the fleets of the Neo Zeon the ability to go about anywhere in the Solar System and use that to their advantage against the Earth Federation. Along with expanding their range and influence to colonize the rest of the Solar System, bringing it all under their control.

However, Haman Karn, being the skeptical, pragmatic and cautious woman, decided to have the Psycho Big Zam to be outfitted with the experimental device instead of using one of Neo Zeon's ships. To her, the Big Zam was a failed relic of the One Year War that couldn't live up to the hype that the deceased Dozle Zabi gave even if it was given the upgrades and modifications, which would be eventually outclassed by the more advanced mobile suits produced by Neo Zeon and even their enemies from the Federation.

And Glemy Toto decided to use one of the Ple Clones to be the pilot of the Psycommu-enhanced Mobile Armor as he needed an expendable clone that can be easily replaceable instead of any of his loyal followers from his faction as part of his sucking up façade to Haman Karn.

Ple Twelve pondered in her mind after remembering the pros and cons from her superiors discussing about it to her, If it works and I'm still alive, the Psycho Big Zam would reach its destination and I will start wreaking havoc on the Federation Forces caught off guard by the sudden appearance of this Mobile Armor from the One Year War, puru! Weaken and bleed them hard enough for the Axis to eventually arrive and take over with minimal resistance...

...Buuuuut if it doesn't work and I'm dead or stuck somewhere in the space, then there's no huge loss for Neo Zeon anyway and victory is inevitable when they get there at their own pace. Except for that poor Dr. George Walton who might get sacked and lose his job or probably executed. He was very confident that his hyperdrive device would work, puru., she then added.

After fully activating the controls, the entire Mobile Armor rumbled, and the clone of Elpeo Ple can feel that the systems are beginning to shift and move and hum around her. From the simple display screens, she can see that everything is doing well so far. The Psycho Big Zam launched away from the hangar of the Axis and flew with the Minovsky Craft System and its legs bent themselves to give more rocket boost and increase speed.

The Mobile Armor exited the Asteroid Belt into the clear space where Ple Twelve can start her first hyperspace voyage without anything blocking its way.

"Mission control, Psycho Big Zam's systems are still green and stable so far, puru. I'm preparing the Hyperdrive Generator.", Ple Twelve reported in the communication channel as she held the joystick controls of the Mobile Armor's console.

The man from Axis' mission control responded from the said channel, "Roger, set your coordinates to Earth Sphere or any of the Lagrange Colonies of your choosing to arrive and attack. Good luck, Ensign Audrey and give those Federation bastards Hell when you get there. Sieg Zeon!"

Setting up coordinates to her desired location which she chose the Earth Sphere, the Cyber Newtype clone of Elpeo Ple activated the the Psycho Big Zam's hyperdrive device after she cheerfully replied, "Sieg Zeon, puru!"

Before her eyes, she can see the blue tunnel from the viewscreen of the Psycho Big Zam's cockpit and it is a good thing that her viewscreen was polarized so she won't get blinded. The Mobile Armor accelerated forward into it, disappearing from sight.


Somewhere in space en route to the Dort Colonies, IBO Universe

The Arianrhod Fleet, also formally known as the Outer Lunar Orbit Joint Fleet, was preparing to suppress the recent Dort Colonies' worker riots that they have set it up on purpose in order to lull the dissidents into false hope of having a chance against them. As their several Halfbeak-class and Skipjack-class ships and a dozen squads of EB-06 Grazes were deployed and flew towards the colonies where they will do their part in the name of Gjallarhorn.

And their commander, Brigadier General Rustal Elion would be pleased of the results once it's done and reported to him on Earth where he was currently holding a meeting with some of the heads of the Seven Stars.

Soon those foolish workers will know their place again... I just love how the same song and dance goes and it never gets old..., Lieutenant Colonel Kevin Marcus internally mused while maintaining a professional face in front of the subordinates going about their duties on the bridge of his ship.

Just as suddenly, a gigantic object appeared out of nowhere in space in front of the Arianrhod Fleet, which the members of Gjallarhorn devolved into abject chaos upon seeing it. Its sudden appearance had caught them off guard and they didn't see that one coming at all.

"WHERE DID IT COME FROM?!"

"WHAT KIND OF SHIP IS THAT?!"

"THAT DOESN'T LOOK LIKE A SHIP!"

"WHY IS IT LOOKING AT US?!"

"HOLY SHIT, WHAT THE HELL WAS THAT ENERGY OUTPUT?"

"OH MY GOD, I'M READING FOUR MASSIVE FUSION REACTOR SIGNATURES!"

Due to the sudden appearance of an unknown entity, Lieutenant Colonel Kevin Marcus widened his eyes in surprise, losing his façade of a professional superior officer in charge of the operation he's supposed to carry out, nearly falling out of his chair of his ship's bridge after seeing a massive white and violet-colored ship-sized object with two massive legs unfolding themselves to clearly walk despite having three rocket propulsion thrusters underneath it.

Sure they were in space, but the movement looked just wrong to him.

And the said object had a single glowing eye that seemed to be glaring directly at him.

"WHAT THE FUCK IS THAT?! FIRE EVERYTHING! NOOOOOOOOWWWWWWWWWW!", he shouted at the top of his lungs, panickily pointing at it.

Meanwhile after exiting the blue tunnel via the experimental hyperdrive of the Psycho Big Zam, Ple Twelve found herself facing a fleet of ships with two unique designs and their several mobile suits looked a lot different especially with their monoeyes. Oooh! So this is what the Earth Sphere looked like. It seems that Dr. Walton's device did work after all, puru!, she thought with a smirk.

Then, thanks to her Cyber Newtype abilities, Ple Twelve can sense the positions of the enemy fleet's crew and personnel within. They're all panicking and running around like headless chickens due to her Mobile Armor appearing before them and they didn't expect her presence all of a sudden. And that also includes hostility which she can see their ships' guns deploying and were about to open fire at the Psycho Big Zam.

Along with their squads of mobile suits brandishing their weapons too as well.

The clone of Elpeo Ple was more than happy to return the favor.

"Alright then, time to give you a taste of Psycho Big Zam's power, Federation scum, puru!", Ple Twelve declared as she activated the Psycho Big Zam's main weapon, the Large Mega Particle Gun through her console's controls.

The said main weapon of her Mobile Armor drew a vast amount of energy from the four fusion reactors and then fired a mega particle beam at the Arianrhod Fleet!

The attack struck several of Gjallarhorn's ships and mobile suits directly, engulfing every single one of them in a blinding overwhelming light and heat. Despite their Nanolaminate Armors attempting to diffuse and deflect the Psycho Big Zam's massive beam energy as best as they can, the mega particle beam was way too much to handle as the special metal paint coating had quickly burned and peeled away into nothingness, completely incinerating the metal and people inside simultaneously.

As a result, all of them then exploded into oblivion!

In a single shot, multiple battleships and mobile suits of the Arianrhod Fleet have been wiped out from existence by the Psycho Big Zam, leaving those who were lucky to not get caught in its range. Lieutenant Colonel Kevin Marcus was among the hundreds of Gjallarhorn casualties that got vaporized by the Mobile Armor's Large Mega Particle Gun.

Admiring the view where she can see the remains of the enemy fleet and mobile suits' debris floating in space, Ple Twelve cheerfully commented. "Now that's total annihilation, puru!"

She saw some of the surviving ships and machines opening fire at her Mobile Armor in retaliation to her mega particle beam attack. To her childish disappointment however, they seem to be using ballistic weapons instead of beam weapons. And they were ineffective against the armor of her Psycho Big Zam other than leaving some scorched marks on the white and violet paintjob.

"The Federation Forces doesn't have beam weapons?... That's weird and stupid of them to not use it, puru. Oh well, if they wanted to die that badly, I will give it to them!", the orange haired Cyber Newtype gleefully declared as she activated her Mobile Armor's Psycommu System and launched out the 12 Funnels from several parts of its body while leaving the 11 Bits inside as the reserve.

There is no need to unleash all of them after all.

Ple Twelve controlled the Funnels and directed them to fire at the surviving enemy ships and mobile suits from every crazy direction to play with her prey. She noticed that her beams were bouncing off from them but yet they're reeling from the force of the blows that pushed them back, which she found it hilarious. She decided to keep peppering them with her Funnels and even targeted their rocket propulsion thrusters at the back to disable them.

"This is fun, puru! It's like playing Ping Pong, Pin Ball or whatever that is Glemy played with the others back at Axis!", she giggled with happiness.

On the other hand at the Sleipnir, Specialist-Major Gaelio Bauduin was also shocked to see the massive being that appeared all of a sudden and then wiped out most of the Arianrhod Fleet with one powerful blast with a handful of survivors. The heir of the Bauduin family immediately recalled the history lessons and remembered about the certain giant monstrosities that almost annihilated humanity 300 years ago in the Calamity War.

And they possessed beam weapons that had caused untold destruction and collateral damage in their path.

"It's a Mobile Armor!", he exclaimed.

Ein Dalton asked as he was also surprised and horrified at the instant defeat of the Arianrhod Fleet at the hands of an unknown enemy that showed up unexpected, "Mobile Armor? What are they, sir?"

Gaelio explained as he watched the footage at how the white and violet Mobile Armor with a single glaring eye was sending out drone-like weapons to toy around with the Arianrhod Fleet remnants mercilessly and sadistically, "Ancient mechanical monsters from the Calamity War, Ein! Gjallarhorn's founder Agnika Kaeiru and the ancestors of the Seven Stars had fought and defeated them with the Gundam Frames!"

The captain of the Sleipnir, Daniel Woren grimly commented upon seeing the massacre before his eyes from the bridge's viewscreen, "Apparently, it seems that they've failed to finish them all off and one survived to get its revenge..."

The other personnel of House Bauduin's personal ship agreed with him after witnessing how the Nanolaminate Armor used by the Arianrhod Fleet was like shredded paper to the Mobile Armor's large beam cannon.

Gritting his teeth and clenching his fists with righteous fury, the purple haired young man quickly stormed off from the bridge as he's unable to stand by and watch the Mobile Armor continue to torture the Gjallarhorn survivors of the decimated fleet at its cruel mercy. "I'm going out with Gundam Kimaris! Ein, with me!", he yelled.

"Yes, sir!", the half-Martian soldier of Gjallarhorn complied immediately as he followed Gaelio to the mobile suit hangar of the Sleipnir to launch their machines into space and stop the Mobile Armor.

The Gundam Frames had defeated the Mobile Armors before in the past and now Gaelio Bauduin will honor his ancestor by using the Kimaris to do it again!

Within the outskirts of the Dort 3 Colony in the middle of the workers' riots that hadn't turned violent yet, McGillis Fareed under the disguise as Montag received a call from his Montag Company ship after informing Kudelia Aina Bernstein about Nobliss Gordon being the one who sent weapons to the rioting workers, and that Fumitan Admoss was secretly working for the man the entire time much to the young woman's distress.

"Yes, what is it, Todo Micronen?", he asked upon opening the pad.

"Mr. Montag, you wouldn't believe what I'm going to tell you! The entire Arianrhod Fleet had been wiped out!", the man with a small square mustache informed in a panicking manner with sweat of apprehension formed around his face.

Widening his eyes in shock behind his mask with a long white wig on it, the blonde man immediately questioned with a double take. "Wait what?! How did it happen?!"

Todo showed the recording footage of the white and violet massive ship with two legs and a single glowing eye unleashing a massive blast towards the Arianrhod Fleet to his employer as he elaborated, "That ship came out of nowhere and blasted the entire fleet from existence! Nothing remained aside from the others who were lucky to not be in range!"

Recognizing the attack to be a beam weapon and realizing what that thing really is, the Specialist-Major in disguise stated. "That's no ship, Todo... It's a Mobile Armor."

"What?! What do you mean, sir?!", Todo questioned with a raise of his eyebrow.

McGillis quickly ordered as time is of the essence, "I will explain later. Todo, make sure the Montag Company ship don't get caught in the crossfire with the Mobile Armor! Inform me if it's going to attack the Dort Colonies at any moment! In the meantime, prepare the Grimgerde for me!"

The former CGS First Group member complied with haste, "Yes, Mr. Montag! Right away!"

Ending contact with Todo, McGillis Fareed made a run across the streets of Dort 3 so that he can get to the space port and reach for the mobile suit launched out for him to pilot it. Now this is unexpected turn of events I didn't see it coming. A Mobile Armor that apparently survived the Calamity War and somehow hid for centuries appearing right when Arianrhod Fleet was about to conduct their sabotage and suppression operation. It is clearly attempting to cripple Gjallarhorn's might by destroying Rustal Elion's elite unit designated as the biggest threat to it. With the Arianrhod Fleet effectively neutralized, the Mobile Armor can do whatever it pleases. ... Not on my watch!, he thought with a frown on his face.

The disguised blonde man hoped that Tekkadan especially Mikazuki Augus, the pilot of Gundam Barbatos had received news of the sudden appearance of the Mobile Armor and they will take action to try stop it or else everyone here dies.


Author's Note: Okay, Chapter 1 of "As Big As a Battleship, Puru!" is done and I hope you like it. Ple Twelve had ended up in the IBO universe and unintentionally wiped out most of the Arianrhod Fleet that was supposed to commit their daily routine of suppressing colony workers' movements at the Dort Colonies with the power of Psycho Big Zam. On the other hand, Gaelio Bauduin is gonna go out and try stop the Mobile Armor with his Seven Stars family's heirloom, the Gundam Kimaris alongside Ein Dalton accompanying him.

And of course McGillis Fareed is gonna be taking action as well and that Tekkadan will indeed take notice of the news of the Mobile Armor's sudden appearance in the next chapter.

Before you wonder, yes, Ple Twelve is Marida Cruz from Mobile Suit Gundam Unicorn but at this time here, she is just one of the Ple Clones with a designated number. Don't worry, she will get that name eventually but under different circumstances here. At least she won't have to deal with the crap that her adult canon counterpart had been through if you know what I mean.

I often scratched my head about the concept of the Clones in Gundam UC as unlike the Kaminoans from Star Wars who can growth accelerate the Clones into fully grown adults, creating them takes a lot of time to grow and develop. And Glemy Toto apparently did all that without somehow drawing attention from Haman Karn, preparing an army of Ples as part of his Glemy Faction to overthrow her and take over Neo Zeon in Mobile Suit Gundam ZZ show.

Here's what the Psycho Big Zam looked like:
