Hello everyone, InterestingAuthor here, I thought a rewrite of the story was due to the fact I need some rest from writing Remnant in Earth, but I had to do some writing other than that. So this is a huge re-write that consists heavily from the Gundam Universal Century materials, but the story is not set in the Universal Century era and the Universe itself, and made a crossover with Strike Witches and Titanfall, including other series that you were familiar with.

GUNDAM Assault: Strike Universe.


Chapter 1: Prologue to War

Mobile Armors...

They were the next leap forward in the history of mankind.

Their origins dated back to the Space Era when the Governments of the new Tech-World, the United Nations, an alliance of nine nations, sought the opportunity to mine resources from the stars in secret. This led to the creation of the first Exoskeletons, however, the Space Flight event remained obscured from the rest of the old Tech-World by the UN Governments.

In 1929, Almost thirteen years after the end of the First Neuroi War, the United States began to enact a top-secret project, with the cooperation between UN's best scientists and International Mercenaries could offer. Choosing the right candidates, first, consisting of mundane soldiers and seconds, Wizards, that led to the ultimate soldiers. After harsh physical training and professional education, they were ready.

In the year 1937, came the Striker Units to arm the Witches, which proved very effective against the Neuroi, but they never expected the true dangers of the Neuroi threat that later appeared in the Second Neuroi War.

'Gigant's'

They were the Neuroi's ultimate trump card, 60-foot-tall sentient mono-eyed Humanoids that are armed to teeth with the heaviest armaments and fueled by the will of their Emperor, unlike their fellow brethren, they rely on tactical warfare and well-organized in strategy.

However, around the same year of 1937, the first Mobile Armor was created, but remained hidden from outside the new Tech-World for a few years until they entered the War shortly after the Neuroi's raid in Pearl Harbor. The Mobile Armors were now proven against the Neuroi's Trump Card.

As a matter of fact, these Mobile Armors, controlled by PILOTS, proved their worth in combat against their Enemies, leading to victory. But this time, there will be another story where history will change its course.


Minna-Dietlinde Wilcke, Diary Log.

6th June, 1940.

'The war with the Neuroi progresses. Two days ago, I couldn't believe my eyes, many soldiers and gallian citizens flooded into the town of Durnkirk. I've seen how many of them were scared; they've lost their homes and their loved ones to the war. Hartmann, Barkhorn and myself are nervous about the situation we're in. We hope for an end to the war, but how long will it be until then? I don't know and neither do they. However, since my previous mission on June 4th, something intense happened.'

Minna and her squad saw the sight of Neuroi goblins swarming over the airspace. Their duty was to prevent them from coming into Dunkirk. However, Minna's superior officer received a call from the Allied HQ.

"Everyone, we need to pull back!" said her captain. "A large swarm of Neurois are heading straight for Durnkirk!"

"But what about the maintenance crew!?" Minna asked worriedly. "They are still in the base!"

"There is no time." Her officer tilted her head sideways.

"What? We're leaving them to die?!" Minna almost yelled at her.

"Listen Fräulein Wilcke, the longer we stay, the higher the risks." She glared back with a cold tone. "That is an order."

Minna gritted her teeth. She wouldn't leave them behind. She didn't want to break the hearts of their families. Just as her Squad began to leave, Minna's face darkened and she flew directly towards the base. Her officer and her comrades looked back with surprise.

"Flight Lieutenant, what are you doing?!" her superior yelled. "Get back here, that is an order!"

Just as they flew to get her back, the Neuroi miasma beams interrupted them.

"Dieser Miststück..." The officer gritted her teeth with anger. "MINNA DU VOLLIDIOT!"

However, Minna ignored her and landed near the Warehouse. She heard the Neuroi's are coming close to their location. She had no time, but she went in.

"Hello? Is someone still here?" she shouted. She heard a grunt.

She sighed in relief, the crew were still alright. Suddenly, a Neuroi beam erupted, obliterating half of the warehouse, but it missed them.

However, they were trapped and the burning building was beginning to collapse. Minna's legs were stuck underneath a wooden pillar.

'After I went inside the warehouse to rescue the maintenance crew, I didn't expected this to happen, A Neuroi beam nearly blow us up, I was injured and trapped inside the burning warehouse along with the crew, I was too stubborn, I didn't just wished to die and just hoped that a miracle will happen... but... it did really happened.'

Suddenly, in a brief moment, an unknown figure walked passed the flames, surprising the crew. His appearance looked alien to them.

He wore a grey combat uniform with a brown scarf, plate shoulders and knee caps attached to it, and a helmet that covered his entire face with a glowing blue T-shape visor.

He shoved the fallen pillars aside with inhuman strength.

"Get out of this place now, this building won't last long," he said in a male voice that rather sounded like it was coming from a radio. "The exit is that way."

They nodded and ran towards the exit, and the unknown soldier walked to the trapped Witch. She began regaining consciousness and was met with a metal boot right in front of her. She continued to look upwards and saw the man, who almost resembled a knight. He lifted the burning wooden pillar and shoved it aside, surprising her with his superhuman strength.

"Can you walk?" he asked.

"N-No..." Her feet were in pain whenever she moved.

"Come on, I'm getting you outta here."

The person began to carry her, bridal style, and ran towards the exit as the building began to collapse.

Moments later she was met by fresh air. They'd made it out successfully.

"Wh-...Who are you?" she asked weakly.

"The name's Kurt," he answered in her native language. "That's all you need to know, the rest is classified."

'He saved me and the crew. I will never forget him.'

After Minna was recovered and released from the infirmary in Dover Base, she almost got de-ranked by her superior officer. Much later, she spotted the same person in the docks who rescued her from the flaming debris.

She saw him sitting alone on a crate, isolated from the others. He removed his helmet and sighed deeply, which caused Minna to blush.

"O-Oh my…" she gasped.

"I can hear you," he said, noticing that she was peeking out from behind the other crates.

This caused Minna to sneak away from him with a flustered face, which made him chuckle.

'I saw his face, his blond hair and his blue crystal eyes. I have seen the only man that caught my interest and my heart. However, I never made the chance to meet him, because I heard he was transferred to Africa to help the Allied forces to fight the Neuroi. I hope that I will see him again one day.'


Five years later, Berlin under Neuroi occupation, Karlsland, 1945.

The sirens wailed as a sign of an attack, alerting aliens with humanoid shapes and who wore black armor with red hexagon patterns. They were the Neuroi.

Since they first appeared in Europe in 1939, humans have gained no knowledge about their origins as they began threatening to destroy mankind. But now, in their failure to overcome the human race, the last pockets of the Neuroi army in Berlin were rushing around to their defensive perimeters to prepare for an impending attack from the human forces.

The Neuroi captain began to speak to his superior in a deep, cold, robotic voice.

"Commander, all troops are waiting for orders."

His commander looked up to the skies and heard a deafening buzz. He saw a dozen planes in a V formation, a mixture of Halifax Heavy Bomber Planes and Armstrong Whitworth Night Bombers that flew in the night skies.

"So... the humans come this far…" The commander snarled and gave an order. "Shoot them down! For the glory of Neuroi!"

A 60-foot-tall humanoid Neuroi roared a battle cry and engaged its overly large machine guns. A barrage of Miasma bullets shot one of the bombers.

["This is Knightfisher from Bomber Squadron no. 109! We're hit!"] yelled a pilot from a Halifax over his radio.

["All Bomber Squadrons! Release the bombs now!"] ordered someone from the leading plane.

The bombers began to drop their heavy payload on the Neuroi defensive positions. One managed to hit one of the Neuroi Anti-Air turrets. Suddenly, the same gigantic Neuroi came into the middle of the streets, aimed its machine gun skywards, and fired at another Halifax bomber until it exploded into a fireball right out of the skies.

However, unbeknownst to them, in the forested outskirts of Berlin, a single Neuroi soldier fell to the ground as its body dissolved into white glitter, leaving it's armor behind. A soldier crouched beneath the bushes, hoping that a Neuroi patrol wouldn't see him. He wore olive green body armor with a brown scarf and a helmet with a blue, glowing T-shaped visor covering his entire head. He pulled out his binoculars and looked over the city.

He zoomed in to look for hostile Neuroi soldiers and activated the thermal mode to spot any signs of movement.

"30 Gigants on the southern defensive perimeters ... 20 Armored Turtles at the west sector..."

Then he looked eastward and saw a dozen of Neuroi Anti-Air turrets shooting down the bombers.

"Looks like the Britannians have pulled back..." he muttered quietly as he looked to the skies.

A little later, he made his way into the city. After the heavy bombings of the Allies, Berlin was now filled with smoke and flames. The US PILOT Commando dashed under the shadow of the debris and hid behind the ruined walls. He heard some marching footsteps, and he peeked out and saw a square formation of Neuroi soldiers and one Gigant marching through the streets, however, he wasn't alone, near his side was a pair Britannian SAS.

"Oi chap, if we keep sitting here and wait 'till they find us, I don't think that will-"

"Listen ye pal, we are getting in, the Orussians are there already on the eastern outskirts and they should be bombing the Neuroi defenses any moment," the commando interrupted.

At that moment, they heard deafening artillery bombings from not so very far away. "Now let's get moving."

After the Neuroi passed through the city, the commando led the SAS squad from out of cover and confirmed it was safe to get across the streets without contacting, but then a laser nearly hit one of the SAS.

"Neuroi sniper! Get to cover!"

Two SAS ducked behind a pile of rubble. The US Commando unslung his Britannian-made AR-15, peeked out, and spotted a sniper from inside the building on north.

"There he is."

"Where?!"

"At that building." The Pilot pointed to a battered motel building. "Fifth floor! At the seventh window!"

"Got it."

One of SAS members pointed his scoped Lee Enfield Rifle, aimed, and carefully waited until a Neuroi ducked out from cover.

The Britannian immediately shot it in the face and saw its body dissolve, leaving its armor behind.

"Got him!"

"Alright, let's keep moving."


City Entrance, Berlin.

Meanwhile, at the main entrance of the city, a large battalion of Farawayland Forces and its Mobile Armors made a breakthrough in the Neuroi's southern defensive line, General Patton looked around until a soldier came up to him.

"General Patton." He saluted. "Rommel's forces have successfully broken the Neuroi's defensive position at the West district."

"Great, that's good news to hear!" he said proudly while puffing his cigar. "After the battle is over, Karlsland will be free from the Neuroi army."

Then Patton looked back to his troops. He saw the nostalgic sight of the Allied Forces, double-barreled M35 Grizzly tanks coming through with soldiers riding on them, helicopters and jet planes soaring through the skies along with the Jet Witches, and the sight of a gigantic floating Enterprise-class ship in the skies. Then three RUTS-37, 60-foot-tall Mobile Armors, strolled the fields to mop up the remaining Neuroi around the area.

"I wonder what Reynard's up to..." He chuckled as he looked back at the city entrance.


Berlin, Karlsland Reichstag building.

The remnants of the Neuroi army stood in square formation. Its commander walked through the path with his engineer beside him.

"Is the portal ready?" he asked.

"It's ready commander, we've tested it and it is successful." The Neuroi grinned. "The machine will save what remains of us."

"The humans are getting closer." The Neuroi commander groaned. "No... It's just him."

"You mean that human wizard known as Reynard Smith?" The Neuroi engineer looked straight at him with curious expression. "I have heard some reports about that human Pilot Commando, isn't he the one who destroyed the Main Fleet in Romagna with a white Mobile Armor?"

"That was the second, after he destroyed our previous hive in Gallia last year. That is why we need to get out from this old world and re-settle our forces in a new world."

A Neuroi officer came by and saluted his commander. "Sir, we've gathered the last remaining Turtle division, we are ready for deployment to the new world."

"Good." He nodded. "Activate the portal and order the troops to enter now; we shall not waste time..."

As the Neuroi commander came to the balcony, he looked down at the sight of six hundred Neuroi Infantry marching to a large circular gate.

Meanwhile, not so far away, a Witch flew ten thousand feet above Berlin.

She had orange hair and blue eyes, wore a light blue Farawayland Airmen service uniform and a light brown mini skirt with protective knee pads, and was equipped with a J-F07V Jet Striker and a heavy GAU-11/7 Gatling gun.

There was a flash of light in the center of the city. "This is Flight Lieutenant Charlotte from 501st. Reynard, can you hear me?"

["I can hear you loud and clear, Shirley, what is it?"]

"I spotted a light coming from the center of the city, where are you?"

Reynard stood beside with the two SAS and saw a bright light from not so far away. "Me and the SAS are located in front the Reichstag," he acknowledged. "Something's crackling over there."

"Say chap, don't tell me that we're dealing another Neuroi Geara Zulu-type?" asked one of the SAS nervously.

"I dunno pal, maybe we're dealing with another one." Reynard shrugged.

As the Neuroi's began to march into the portal, Reynard and the SAS hid behind the fence wall and peeked over. He was surprised to witness what the Neuroi were doing.

"Hey Jenkins, are there any Neuroi soldiers behind us?" the Pilot asked.

"No sir." He shook his head.

"Alright mate, let's see what these Neuroi are up to..." He thought for a moment. "Alright, here's the plan."

As the Neuroi Commander stood proudly, he patted his engineer on the back.

"You have made good work, Aphobis. With the connection between the two worlds, we can come back to this world with a vengeance that the humans will never forget."

"I would appreciate that, Commander Xenos." Aphobis chuckled.

"Aphobis! We have a problem," one of the Neuroi engineer yelled. "There is a malfunction in the machine."

"What?! Show me!"

As he inspected the controls of the machines, something went oddly wrong.

"What in the name of Neuroi did you do?!" Aphobis yelled.

"I didn't do anything, Head Engineer!" he said. "It was processing itself in good condition, but an unknown virus hacked into the data for unknown reasons."

"Halt!" Xenos stopped the Neuroi soldiers from marching in, and they looked towards their commander. "Who did this?!"

The Neuroi looked at each other in confusion, until an olive green soldier appeared on the rooftop of the Reichstag building.

"Hey Xenos!" he yelled. "Remember me?"

The commander of the Neuroi army snarled in anger.

"You!" He pointed out angrily.

"Yep, you still recognize me?" Reynard teased with a smirk under his helmet.

"Kill that pesky human!" Xenos barked.

At that moment, Reynard felt a large being overshadow him. He turned to see it looking at him directly with its large mono-eye, and he dodged a fist from the Gigant.

"Boys, let's bring them a surprise!"

"On it!" said Jenkins from the radio.

On the other side of the building where the SAS were stationed, Captain Jenkins and Corporal Wilbert used an MG42 against the Neuroi infantry, killing a chunk of them and scattering their alien opponents into cover.

"Aphobis, fix the machine now!"

Aphobis nodded as he tried to get rid of the virus. On the rooftops where the Pilot engaged against the Neuroi Gigant, a deafening screech of a rocket was heard as it hit the Gigant in its core. Reynard looked up into sky.

"It's about time then, Shirley," Reynard muttered. "Alright, let's do this."

As Charlotte dived down out of the sky with firing her minigun and distracting the Gigants, Reynard leaped out from the rooftops and fired his AR-15 Assault Rifle.

This did not make Xenos happy to see. "How long will that machine finished?!"

As the engineer got rid of the virus, he looked back to his commander.

"It's done!"

"Turn it on now or we will be dead, a shame to the Neuro Empire!"

Aphobis quickly nodded and re-activated the portal.

A flash of light nearly blinded Charlotte and Reynard, and the Neuroi infantry stopped firing and heads for the gate. However, this time the portal's color changed from blue to orange, and suddenly, a bleeping sound came from the controller.

"S-something's not right..." the Neuroi engineer stuttered.

Reynard and Charlotte observed the situation and noticed that the gate portal was erupting large sparks of electricity and surging.

"Are you seeing this?" he asked through the radio.

"Yeah, But I have no idea what it is."

Suddenly, a large shadow covered the Reichstag building. They looked up to see a large, floating Enterprise-class ship with its name painted on the side, John Sierra.

["This is Captain Colin Cutter of the ship USS John Sierra, we're preparing an aerial bombardment, all allied units in the city center must get out ASAP!"]

Suddenly, a flash of light shot out from the center of the city. General Patton looked down from the higher terrain as the rest of Allied soldiers and Land Witches saw it.

"What the hell is going on?" he said in disbelief.

On the western side of Berlin, Commander Minna landed nearby Rommel and witnessed the light from beneath the USS John Sierra.

"Field Marshal Rommel, what's going on over there?"

"I don't know fräulein Wilcke," Rommel said with a worried expression, pulling out his handkerchief and wiping the sweat from his forehead. "We heard Flight Lieutenant Charlotte's latest transmission and she's at the Reichstag Building. She paired up with Major Reynard, who also had a pair of Veteran SAS with him."

Minna's eyes went wide as she tried to get in contact with her radio. "Charlotte! Reynard! You must get out of there!"

Meanwhile, with Reynard and Charlotte...

"Charlotte!? Major Smith?! Can you hear me?!"

"M-Minna?" Shirley asked through her radio.

"I will say it again, Yeager! This is urgent! You and Major Smith must get the hell out of-"

However, it was too late. They were interrupted as the light began to consume them. In a moment, it flashed so bright as they shielded their eyes and disappeared. The Allies in the outskirts of Berlin were shocked as the USS John Sierra vanished from thin air.

"What the... hell happened..." General Patton nearly dropped his binoculars.

Meanwhile Minna stood silent with wide eyes. All she heard was static, and as she fell to the ground, crying, other allied soldiers looked at her with worried expressions.

"N-No... Th-This can't be..."


Location: Gallia, somewhere in Normandy, Unknown Year, Alternate Reality (SW Universe).

Blackness, all she could see was blackness, until she heard a sound of waves and suddenly felt something cold and wet. Charlotte jerked out of her sleep and found herself on a beach.

"Wh-What was that? Wh-Where am I...?"

The Farawayland Witch stood up and shook her head from dizziness, but something was not right.

"My Striker! Where is it?!"

She looked left and right frantically, but then found two objects buried under the sand. She pulled them out and found that they her J-F07VJet Strikers. She sighed in relief, but then another thing came to her mind.

"Reynard!" she gasped. "I must find him! But... where should I go?"


501st Base, SW Universe.

"One page finished..." Minna sighed. "And one hundred more to go..."

"It'll be more stressful if you keep doing that," Mio said with her arms crossed. "Why don't you take a rest?"

"I can't, these papers are really important." The red-haired witch groaned.

As the Wing Commander of the 501st kept trying to get the papers finished, an earthquake rumbled in the office and a loud crash was heard in the hallways.

"Kyaaaa!" one of the witches screamed from outside.

"What was that?!" Minna stood.

The two witches exited from the office and ran through the hallways.

They heard a commotion coming from the kitchen, and Mio immediately opened the door.

"What's going on here?!" Mio unsheathed her Reppumaru and saw Lynette Bishop and Yoshika Miyafuji hugging themselves with frightened expressions. "What happened?!"

Lynette said nothing but shakingly pointed her finger to a figure that stood up groggily from a pile of broken ceramic plates and bricks.

"Uhh... What was that…?" the person groaned as he tapped his helmet, then slowly looked around. "Where... am I?"

"TONERRE!"

*ZAP!*

Suddenly, he felt a jolt of electricity in his back and fell to the ground, unconscious. The four girls looked up and saw Perrine holding a rapier.

"Perrine!" Mio shouted.

"Sorry, but I had to do it before this brute-looking person might have harmed us." Perrine said with a nervous laugh.

Minna went over to the unconscious body and inspected his outfit. It was unlike anything she'd ever seen. He wore in an olive green military outfit in an unknown style with metal plates attached to its shoulders and knees, a helmet with a blue T-visor that completely obscured his head, and a brown scarf. She noticed weapons slung on his back, a pistol in a hostler and even a dog tag hidden under his scarf with his identity.

"Reynard Smith... U.S. Mobile Armor Corps Specialist?" she read. "A... Liberion?"

"Umm... so what are we going to do with him?" Mio asked.

"Put him in a cell and wait until he wakes up," Minna ordered. "We don't know how this person got here. Inspect his weapons and his belongings, there's something suspicious about him. He could be one of Trevor's men."


Chapter ends.
