Chapter 1: New Arrivals

It has been three long years. Three years since the Advent Corporation managed to finish their Avatar Project, and fully enslave humanity. After that, they attacked the Avenger, the famous mobile fortress of the XCOM Resistance, and nearly took it down. After a long battle, the Resistance managed to drive them off, but only a handful survived, while the rest was either slaughtered, or captured.

In those three years, Advent managed to take over mulitple realities, enslaving their human population, and likely every other intelligent species. For XCOM, this was a fight they couldn't win. At least with only thirty people left on the ship, and with even more limited ressources than before.

For three years, the remains of XCOM hid in the shadows, unable to do anything. But with the recent discovery of a strange alien artifact, it should all change.

"Tygan. Shen. Did you find something out?" Bradford asked, as he and the Commander entered the Shadow Chamber, which was located in the lower parts of the ship.

"Well, the Artifact is certainly strange. It's not of Advent origin, and over thousands of years old." Tygan said.

They found the artifact in the middle of a crashed Advent vessels, and it looked like Advent wasn't to eager to get it back.

"However..." Shen activated a terminal, and showed strings of data. "We've found datastrings in there. Whoever created this artifact, knew about the Ethereals."

"That's unsettling." Bradford replied. "Is there any indication what it does?"

"And that's the interesting part." Tygan answered. "It has similiar energy readings to the gate we've found three years ago."

"So, it is a portal." The Commander said sternly.

Tygan nodded. "Three years ago, Advent took the Portal back from us. But with this object, we might be able to replicate it's functions."

"Uhm, you might want to see this." Shen interrupted, and everyone gathered around her and Rover. The little robot was showing a message on his screen. "Rover just finished decyrpting the last datastring." Shen explained. "The first ones seemed like random numbers and letters, but this one actually makes sense."

Bradford read the message. "To the Reclaimers who read this message, you are in grave danger. The beings, known as Ethereals, have taken over the galaxy. But fear not, this device can give you the heroes you need. It will send waves through the dimensions, and give you heroes from conquered worlds, before they've been conquered."

"That doesn't sound like a good idea." Tygan muttered.

"I don't know..." The Commander replied. "We could use that Artifact. If the message is true, then it might be our chance to finally get rid of Advent. Once and for all."

Bradford sighed. He knew that the Commander was right. He always was. And they didn't spend all those years hiding just to turn down a chance like this. "Can you activate it?"

"Probably. It will take a day or so." Tygan and Shen replied, and started to work on the object.

Bradford and the Commander left the Chamber, and walked to the bridge. "You think this will actually work?"

"I see it as our only chance. We don't know what kind of people live in those other worlds. I know that we are taking a gamble, but it's the only chance we've got."

They entered the bridge, and looked at the Hologlobe. It showed the areas occupied by Advent in a deep red, and those occupied by the Resistance. Most of the Earth was completely under Advent control, while only a few Resistance havens remained, and only in secluded areas like the Himalaya.


It took a day, just like Tygan promised, but the Artifact was all powered up. They plugged it into the ship systems, and first calculations told them that the activation process would most likely result in a shut down of the entire ship. Thus, they landed in the middle of the South American Jungle, so that Advent couldn't use the chance that easily.

"Ready?" Tygan asked.

"I'm still not sure about that." One of the highest ranking soldiers, Zhang, said. He was the only soldier left from the original war years ago, and was now highly decorated, and a loyal veteran. If it weren't for Bradford and the Commander, he'd be the highest authority for the operatives.

"It will work." The Commander said.

"The chances of success are incredibly low." The only SPARK unit in the room said. "Not that anything in this dump ever worked out."

"Watch your mouth, Julian." Bradford said. He had his problems with the SPARK, mostly due to his alttitude, and that he tried to kill Shen and some operatives, but Shen wanted to keep him.

"Okay..." Shen said, and tipped around on a terminal. "It goes off in three."

"Two."

"One."

"Go!" Shen pressed a button, and a bright light illuminated the entire room. Even as they held their hand in fron of their eyes, the light shined through, enabling them to see the bones inside their hands.

The light was only there for two seconds, until it dissipated. "Did it work?" The Commander asked.

As the light disappeared, it revealed probably the strangest group of people they had ever seen.

One of the new arrival, wearing a red and black dress with a cape, blinked to get the light out of her silver eyes. "Where are we?" She turned around, and looked up at one of the other arrivals. A man, standing over three meters tall, wearing a futuristic, green armor with a golden visor. "Oh my gosh! A robot!"

The 'robot' looked at Bradord, and aimed his grey rifle at him. "Identify yourself!"

Bradford held up his hands. "Central Officer Bradford. Who are you?"

The man lowered his rifle, but kept it ready, in case something would happen. "Master Chief Petty Officer John Sierra-117."

"Good to meet you." The Commander shook his armored hand, and noticed the strong grip.

He looked at the other arrivals, and he became concerned. There were seven other people in armors similiar to John's, although they all had different colors, ranging from a maroon red to a deep blue.

That wasn't a big problem though. The weapons on their backs suggested that they wear used to combat. However, most of them were teenagers, and they looked more scared than anything.

One of the teens turned towards one of the girls standing next to him. He was wearing a white shirt, with a green, gold-trimmed mantle. "I don't know what's going on, but this is probably your fault."

The one girl he was pointing at got angry. "What? I didn't do anything!" She had light blue hair, and wore a dark blue dress.

"Okay, what the fuck is going on here?" Another girl asked. She had long, yellow hair and lilac eyes.

"I agree with blondie here." One of the armored soldiers said. His armor had a dark red color, and the gun on his back looked a lot like a Shotgun.

"This isn't what I expected." Bradford muttered.

"I told you so." Zhang an Julian said at the same time.

"Listen. This might sound unbelievable..." The Commander started. "But we used this device behind you to transport you here."

They all turned around, and looked at the Artifact. "This is Forerunner." The Chief muttered.

"According to some sort of prophecy, you seem to be the ones who are destined to save humanity." Everyone turned around again, and looked at them in shock. "Follow me please."

Without any other option, they followed the XCOM officers to the bridge, and looked in awe at all the technology. The Commander positioned himself in front of them. "Twentythree years ago, a fleet of Alien ships arrived at Earth, and soon a war between them and the United Nations started. We at XCOM fought at the front, but were eventually defeated. Soon, the United Nations swore loyalty to the Aliens, and the Advent Corporation was founded. Twenty years later, a second war started, but we lost again. After that, Advent used a Psionic Gate to travel between realities, and took over other worlds." The Commander looked at the baffled newcomers. "Your worlds."

"No, that can't be." One of children said. She was wearing a white dress, and a rapier was hanging on her hip. "Remnant was never taken over by Aliens. We would've known that."

"Unfortunately..." Tygan said. "It isn't that easy. The device took you from a time when your worlds were still free. That means at least from three years ago."

"Yeah, I still don't believe that shit." One of the armored people said. His armor had a orange color.

"Then we'll show you the evidence." Bradford said, and started typing on a terminal. A couple of screens appeared, showing footage of different worlds and cities.

"That's Beacon!" One of the teenagers said. She was wearing a brown coat, and black aviators, while carrying a handbag. She pointed at one of the screens, showing smoking remains of a castle-like building. It looked like a giant meteorite crashed close to it. Advent ships were circling above the ruins.

"It's... destroyed." A girl next to her said in fear, and held her bunny ears in front of her eyes.

They all searched for their appropriate homes, and saw the same, horrifying scenes. Spaceships hovering above destroyed cities, towns and worlds. Advent facilities and cities were built above the ruins.

"But how..." One of them asked.

"How could they defeat the UNSC?" The Masterchief asked, more himself than anyone else. "Or the remains of the Covenant?"

"We have a proposal for you." The Commander said, and all attention shifted to him. "Do you want to join XCOm, and save your worlds?"

Everyone looked in shock at him.

"I can understand your hesitation, but this is urgent. We'll give you some time to think about-" Bradford explained, but was interrupted.

"Sir!" One of the officers on the bridge yelled. "Advent forces incoming!"

"Is the Avenger ready to lift off?" Bradford asked, and Shen started typing on a tablet.

"Not yet. In thirty minuted. I'm afraid we'll have to hold them off for that time."

The Commander and Bradford turned around to the arrivals. "Get to the entrance bay. We only have limited manpower, and need all the help we can get."

"But-"

"Go!" He yelled, and they all started to run.


Thanks to the signs on the way, and the people running into the same direction, it wasn't hard for the group to find the bay. One side was open, leading outside. Soldiers were positioned along barricades, and two turrets were looking around, scanning the outside for enemies.

"What's going on?" One of the girls, with a long, red ponytail, asked.

"Advent Bastards are coming in." Zhang replied. He carried a heavy machinegun. "And we have to hold them off." He getsured to some crates in the corner. "There are guns in there. Take 'em, and lend us a hand."

Everyone who didn't have a weapons ran to the crate, and took a gun. They all were automatics, and pretty easy to use. "They're coming!" The Chief yelled, and aimed at the entrance.

One of the armored soldiers activated a hilt on his hip, and a blue glowing plasma sword appeared. "Let them come."

In the distance, they were able to see multiple red lights closing in. As they came close enough, they were identified as troop carriers, using four engines to stay in the air.

The ships went down, and multiple soldiers, wearing black armor, with a helmet that hid their faces, jumped out. Red glowing rifles hang on their back. One of them had a red armor, and wore a red cape.

"Fire!" One fo the soldiers yelled, and shots started soaring through the air. Multiple Advent Soldiers went down, and the rest took covers behind trees.

"Donut! Can you get them outta there?" One of the armored soldiers said in a rough voice. A pink armored soldier nodded, and grabbed a grenade, before throwing it. It landed next to a group of trees, and blew up. The resulting fireball engulfed the tree and Alien.

"Good throw." One of the girls, with long black hair, complimented him.

"Thanks. Comes from years of tossing." Multiple XCOM soldiers turned around, and stared at him.

"Twenty more minutes!" Shen yelled over the comms.

"Alpha Team, take do-" One of the soldiers was interrupted, as something slithered near him, and started to wrap around him.

"Shit! Viper!"

The girl in the red dress grabbed a device from her back, and transformed it into a giant, red scythe. She charged forward, and to everyone's surprise, turned into rose pedals. One swing later, and the Viper was cut in two. The soldiers, as well as the Aliens, looked at her in disbelief.

"Thanks." The Soldier said as he catched his breath.

Suddenly, another woman, wearing a white knight armor, stepped in front of the girl. "Me too!"

"What?" The soldier and girl asked both.

"Come on, you don't stand a chance against guns." The boy with the white shirt said, and dragged her back.

"Uhm, we might've a problem!" One of the soldiers said, and pointed at the woods.

A robot left it. It looked like a bulky mech, with a green glowing cockpit. Massive pumps were leading from the Cockpit to other parts of the armor.

"Get the Amor piercing rounds!" Zhang yelled.

"Don't worry." One of the girls said, and stepped forward. She wore a red robe and black cape, and a black wicth hat. Her eyes were a deep crimson. She aimed a wand outside, and started to cast an incantation.

"What's she-"

"Explosion!"

Red glyphs appeared outside, and a second later, a giant explosion destroyed the forest in front of the Avenger, as well as any Advent groups. Hundreds of broken and burned treestumbs were visible as soon as the smoke disappeared, and the wrecks of crashed troop carriers laid on the ground. The robot itself was completely destroyed.

"That was awesome." One of the girls with a giant hammer, yelled, and turned around. She saw the witch on the ground.

"I can't move."

"What in the hell happened there?" Bradford yelled over the comms.

"One of the girls casted some sort of spell." Zhang answered, not trusting his own words.

"Come again." Bradford replied.

They looked outside, and noticed that most of the Advent troops were keeping their distance. "Hah! The fuckers are afraid!" One of the the soldiers yelled.

"Yes, run!" The dark red armored Spacemarine yelled. "Ya dirtbags!"

Zhang picked up the Witch, and moved her arm, to make the Aliens think that she was about to cast another spell. It worked, and they stepped back even further.

"Ten more minutes!" Shen said.

The stalemate was broken, however, as two more dropships closed in, ready to drop off reinforcements.

The turrets shot at the ships, but it didn't do a thing. More Soldiers jumped out, accompanied by two MECs. They instantly activated the weapon on their shoulder, and rockets turned the turrets into smoking wrecks.

John aimed at the robots, and shot his Rifle. Bullets hit them, but didn't do much. The robots aimed their massive guns at XCOM, and shot. The energy ripped open the chest of one soldier, and another one threw a grenade. It damaged the armor of one robot, and the Chief used the chance to run out, and attack it. He stuck a grenade into one of the cracked armor parts, and the Robot was ripped apart. The other one turned his gun around, but the Spartan knocked it away, and slagged the Robot, sending it flying back.

A flying ball flew towards the Robot, and exploded. It destroyed the Robot. The Chief looked back, and saw Julian, as the ball flew back to him.

"We're ready to go!" Shen yelled, and the Cheif ran back inside. Advent opened fire as the bay closed, and the Avenger left the site.

The soldiers inside cheered, and one of them carried away the fallen. "That was tough." The girl in red said, and approached the Chief, as well as Zhang, who was still carrying the witch. "Ruby Rose." She shook their hands.

"Colonel Zhang." The man replied. "Nice to meet you." He turned towards the Chief. "You are good."

"Thanks." The Chief replied.

Zhang looked at the girl, which slipped out of his hands, down on the ground. "And what's your name?"

"Megumin."

"Can you move?" The Masterchief asked.

"I can only use my Explosion magic once a day. It takes all my mana." She replied, getting confused looks.

"Mana?" The Chief and Zhang asked

"Are you okay?" The girl with blonde hair asked, looking at Ruby.

"Yeah, I'm okay, sis. By the way, did you do anything?"

Yang coughed, and pointed into a corner, where a dead Advent soldier was leaning against the wall. His head was bashed in.

The Chief looked at the other armored soldiers, and walked up to them. "Are you Spartans?"

They exchanged confused looks. "Uhm, no. We're simulation troopers."

"But you're wearing Mjolnir." The Chief replied.

"That's not Mjolnir. That's standard issue combat armor." One of the soldiers, wearing a maroon armor, explained.

"I guess we're from similiar timelines." One of them, wearing a deep blue armor, said.

"Wow, Caboose actually had a reasonable thought." The teal one with the sword said. "By the way, I'm Lavernius Tucker." He pointed at the others. "Those are Grif, Sarge, Simmons, Donut and Lopez."

"Ola." Lopez replied.

"Why is he speaking spanish?" Zhang asked, but didn't get an answer.

"Ladies and Gentleman." Everyone turned towards the entrance, where Bradford was coming through. "It looks like we made the right choice, at least for some of you. I'm sure you all are tired. There are some rooms ready for you. Go and get some sleep. We'll get your answer tommorow." He left again, and everyone followed Zhang to their rooms.

The rooms were scattered around a central living area, which consisted of a table with chairs and a sofa. The rooms themselves all had four beds, with a small table in the middle.


"So, what do you think?" Ruby asked, and sat down on the edge of a bed. It was surprisingly comfortable.

"Well, they ripped us out of our lives, and now want us to fight a war against an Alien Empire." Weiss replied angry. "Why should we help them?"

"Because it's our duty as huntresses." Ruby said. She had to admit, Weiss had a point.

"I agree with Ruby on that." Blake said. "If the footage is right, then there's no point in going home. Even if we could go back three years, we'd still be dead when Advent arrives."

They heard a knock on the door, and opened. Their friends entered the room. "So, did you decide?" Jaune asked.

"We'll help them." Weiss said with a sigh. "And you?"

"We'll definitely help." Nora said. "I wonder if that one girl can show me that explosion stuff."

"Don't." Ren deadpanned.

"We'll help too." Coco said, and her team nodded. "We'll kick them back to whatever planet they came from."

"And what do you think about the others?" Yang interrupted.

"That giant is certainly strong." Fox pointed out.

"Yeah, he beat those robots effortlessly." Velvet agreed.

"And the other Space Marines seem capable too." Yatsuhashi said.

"Okay. Then we'll do it." Ruby said, and punched into the air. "We'll do this. For Remnant!"

Everyone put their hands in the middle. "For Remnant!"


"This is fucking bullshit!" Grif yelled angry. "Those assholes dragged us into this!"

"Calm down. I'm sure they didn't do that on purpose." Tucker said.

"What? Are you going to fight these Aliens?" Grif asked.

"Sure. We don't have any reason to go back." Tucker replied. "Sarge is on my side, right?"

"Presicely. Not only is this a new war we can fight, the chances that Grif dies horribly is incredibly high! Hopefully he gets injected with an Alien fetus."

"Like Tucker." Caboose added.

"I'm not going to get raped by an Alien!" Grif yelled.

"Dude, either you help us, or go back alone, and face Advent when they invade." Tucker said.

Grif sighed. "Okay. But don't expect too much from me."

"We never do." Sarge mocked him.

"By the way, where's Donut?" Tucker pointed out, and looked around.

"He has his own room. Would you sleep in a room with him?" Simmons replied, and Tucker nodded in agreement.


"So, that was it with the Devil King?" Aqua asked, nearly in tears. "I'm never going to become a goddess again!"

"I had fun." Megumin said.

"I like this." Darkness added. "Millions of Aliens attacking me..."

"I just want to point out that your armor won't protect you against them." Kazuma said. "Also, please don't be turned on by the Aliens."

"What do you think?" Megumin asked their party leader.

Kazuma thought for a moment. "We can't go out there, that much is clear. I'd say we help."

"You want to help out against Aliens?" Aqua asked in surprise.

"Well, it is pretty cool. Also, I finally have access to technology again. I hope they still have the internet."

"And what's with the Devil King?" The prior goddess asked.

"Advent probably killed him already." Darkness pointed out.

"Right. When we defeat them, I might get my old place again." She replied, now just as determined as the rest of them.

"I'm happy as long as I can use explosions." Megumin said, and fell asleep.

"By the way, what's an Alien?" Darkness asked, and Kazuma sighed.


The Chief was walking around the Avenger, trying to get used to the ship. He had to admit, it was massive. For him, the decision wasn't hard. It was not only his job as a Spartan, but he also defeated the Covenant already, so another Alien empire wouldn't be too hard.

"Chief? Do you really think the Artifact was of Forerunner origin?" A female voice in his head asked.

"It looked like it. I've read the message on the robot. It called us Reclaimer. There's no doubt."

Cortana appeared on a close holoprojector. "Why would the Forerunners know about all this?"

The Spartan shrugged. "I have no idea, but it seems like they did." He looked through a nearby window, and saw a room with guns. "Time to get used to their weaponry."


Thanks to the Avenger being high in the air, it was easy to spot the morning sun through the windows. Everyone had gathered on the bridge, to tell the Commander and Bradford their decision.

"So, what is your decision?" Bradford asked, as he stepped in front of them.

"We'll help." Ruby said, and gestured towards her Team, JNPR and CFVY.

"We will too." Sarge said, and heroically cocked his Shotgun.

"We want to help." Kazuma said.

"We already know the answer from the Chief." The Commander said. "With that, I welcome all of you to the XCOM Project. From now on, we'll try to free humanity from the hands of Advent."

"What now?" Pyrrha wondered.

"We'll show you the types of enemies Advent has in stock for us, as well as test your abilities with weapons. After that, we'll assign a class to you."

"Class?" Simmons asked.

"XCOM likes to put its soldiers into one of five classes." The Commander explained. "Rangers, who use swords and shotgun, and are experts at close range."

"Sharpshooters, who specialize in taking down targets from long distances." Zhang added.

"Specialists, who use a drone to either heal and assist their comrades, or deal damage to enemies, as well as hack targets."

"Then there's the Grenadier, who uses heavy equipment to blow enemies up, and get rid of cover." Noras, as well as Megumins eyes widened as they heard that.

"And finally, we have the PSI operative, who specialize in using their mind for things like mind control." Bradford finished.

"And how do you determine our class?" Coco asked.

"Through extensive testing, where we judge your abilities." Zhang answered.

"Uhm..." Ruby spoke up. "What's with those of us that already know our abilities?"

"Those will be assigned a class based on those abilities." The Commander replied. "Now, please follow Colonel Zhang. He'll teach you about our enemies."

"Come on." The Colonel said, and left the bridge, followed by the new soldiers.

"So, what do you think?" Bradford asked.

"I think that, with the right training, they'll make good operatives." The Commander responded. "I just hope it'll be enough to kick out Advent."


And the start of my fourth story.

I had the idea to write this when I recently played XCOM 2. I like to customize my soldiers to make them resemble characters form games, movies and series (And I'm sure I'm not the only one who does this), and I thought: Hey, why not try to make a story out of it.

From the beginning, RWBY, Halo and RvB where settled as Franchises that would definitely play a role, so I decided to determine the last one randomly. To do that, I wrote down some Franchises I like, and assigned everyone a number, before rolling a dice one hundred times. At the end, the one with the highest amount of rolls won, in this case , I think the cast of Characters can make for some good interactions, as well as combat scenarios.

I set XCOM and RWBY as the franchises, since XCOM is the main setting, and most of the characters are from RWBY.

As for the rough outline for the story, it's not going to follow the events of XCOM 2, and is set in a timeline where XCOM lost shortly after finding the Psionic Gate. However, some of the special missions are still going to happen, since XCOM didn't do them during the war, like the one where the player first meets the Viper King. Also, all three Alien Leaders are still alive.

It's not only going to play on Earth either, and the other worlds like Remnant will appear later on, just like more characters will appear.

Of course, it's gonna be a lot of Characters in the beginning, but later one, the Chapters will focus on certain groups.

It also doesn't have any real schedule when new Chapters are released, and they'll most likely come when they are ready.

And in case someone wonders when the characters came here:

RWBY: Between Volume 2 and 3

Masterchief: Shortly after Halo 3

RvB: Between Season 13 and 15

KonoSuba: After Season 2

With that said, I'm happy about every bit of Feedback. Enjoy the story.

XCOM belongs to Firaxis Games; Halo belongs to 343 Industries and Microsoft, RWBY belongs to Rooster Teeth; RvB belongs to Rooster Teeth; KonoSuba belongs to Shousetsuka ni Narou
