Prologue: Breach of Protocol

Teamwork. While others may view it as a major weakness, any pilot and titan pair could say otherwise. A pilot could take on hundreds of Riflemen and SPECTRES easily, but against bigger targets like Titans and Reapers, even the best have little chance of victory. A Titan could also take on countless soldiers and Titans, and make thousands of calculations per second. Although, without the creativity of a pilot, Titans became akin to that of their Reaper counterparts.

However, link a pilot and Titan together, and suddenly, Hell arrives for the opposition.

Cooper looked down at the datacore of his partner and friend BT. They'd been through hell together, and they would need to one more time for the sake of the Militia. He looked back up at the chassis of the Titan Sarah called for him. He recognized the grey and orange paint from a simulation not too long ago.

Lastimosa, still looking out for me, huh? Jack thought. He slowly inserted the core into the Vanguard chassis, and took a step back.

Here goes nothing.

The Titan took the core into its optics, and blinked, adjusting the new device. It looked around while Cooper stood, breathless.

"Hello, Jack."

BT-7274 stood up.

"Glad to have you back in one piece, BT." Jack grinned. His partner- no, friend, faced him.

"Over twenty-five thousand actually. BT-7274 online and ready for combat." The cockpit opened.

Cooper ran up the top of the Predator cannon and into the seat. BT's doors closed, and his view screens went online. Cooper gave quick systems check before he and BT began walking toward the Fold weapon. Cooper turned on his comlink.

"Cooper, I'm throwing everything I got at the IMC, but it's not going to be enough to stop the Fold Weapon!" Sarah Briggs shouted. "I need you to get inside the control room!"

Sarah continued relaying orders to the fleet, but BT and Cooper knew what they had to do. They began to sprint toward their goal, hailed by bullet fire. Their steps boomed throughout the battlefield, the volume only matched by the gunfire. A small squadron of SPECTRES blockaded a bridge in front of them.

Cooper smiled.

He dashed forward, sending BT over the bots, promptly squashing all of them. The duo now faced a literal uphill battle. BT revved up the new Predator cannon. A Tone and Ion Titan dropped in front of them. BT unloaded his rounds directly into the face of the Tone, while dodging the Ion's shots. In no time, he shredded through the shield and made the Titan explode.

BT looked to the skies. The Militia fleet begun bombarding the platform, and both pilot and Titan made a break for the control room. They ran, blasting through numerous grunts and Reapers while the Militia took out the AA guns and Titans. When BT and Cooper arrived at the doors of the room, a Ronin and Ion Titan burst out of the doors.

"No match for us, Militia freak." said the Ronin pilot.

Cooper activated the Power Shot at the Ronin, but was countered when the Titan blocked it with its sword. The Ion Titan also began firing its spread shots at BT and Cooper. BT's shields went down, and Cooper quickly pulled up the Vortex Shield. However, it was getting quickly getting drained by the onslaught of laser and lead fire.

"You're more like a Rifleman than a pilot!" taunted the Ion.

Cooper ignored the insults and focused on the situation. BT's hull was rapidly wearing down and the Vortex Shield was going into overload. Then BT said the most beautiful four words.

"Smart Core Fully Charged."

Reflecting the shots from the shield back at the Ronin, staggering it, Jack activated the Smart Core for BT.

"Smart Core Online."

BT's Predator Cannon unloaded a seemingly infinite amount of rounds right into the weak spots of the Ronin class Titan. Within seconds the Titan's shields went down, and so did the Titan, exploding in a massive fashion. Cooper and BT turned to the Ion, unloading the rest of the Smart Core's charge into its hull.

"Gah!" The Ion's Pilot screamed as the Titan blew up in a large fireball. The doors of the control center opened, and BT and Cooper walked in.

They were met with a long corridor, short so that BT had to crouch to walk through. As he began walking, scores of IMC Riflemen and SPECTRES poured out from left and right rooms of the hall. BT stopped. They began running toward the back of the hall, just where BT needed to go. Cooper smiled.

"BT, activate the power shot."

BT complied, with the Predator Cannon quickly revving up and firing a quick shotgun blast in front of them. The hall burst into a cloud of red mist and electrical wiring.

"Nice shot BT." Cooper complimented.

BT made a 'thumbs up' in front his optical, indicating he agreed. However, BT looked at the Predator Cannon.

"Predator Cannon out of ammo. Resupply necessary."

Cooper directed BT behind them, to the scraps of the Ion. BT bent over and picked up the Splitter rifle. He also scanned the core of the Titan, giving him access to the Titan's laser core. Once they were done, the went down the hallway. The Vanguard spoke.

"Jack, we must stop the IMC from activating the Fold Weapon at all costs. Our failure would result in the destruction of the Militia planet Harmony."

All those lives…

"Understood BT."

They went down the hall, hearing IMC General Marder's voice over the PA.

"All IMC personnel, evacuate the facility. Activate the Fold Weapon."

BT and Cooper had to hurry. They quickened the pace, going into slight overdrive for BT.

The female Facility PA announced, "Initiating Preliminary Fold Weapon Power Systems."

The duo went outside to the balcony, watching as Goblin dropships jumped out of the system. The Ark weapon's rings began spinning faster.

"Powering up Target Responders. Awaiting orders, General."

Jack could feel the arrogance of the General as they passed a part of the weapon within the facility.

"Set location to the Militia planet Harmony."

Cooper sent BT's engines into full overdrive, and they sprinted down the hall. They had no time to waste. Seeing battery storage units, BT ripped them apart and loaded them into his system, repairing his functions and reactivating his shield. The pair saw a door to the right, which contained the center of the weapon. BT kicked the door down, revealing Mercenary Blisk and Slone, loading the weapon in place. Blisk was conversing with Marder's hologram.

"You have your money Blisk. Now go. My forces will take it from here." The hologram dissolved.

"About bloody time they do something." He muttered. He smiled as he saw BT. He walked past Slone, saying, "I think our Militia Pilot's trying to be a hero. Keep the salvage. It's all yours."

Blisk left the room as Slone cracked her knuckles menacingly. "Who said anything about salvage? I'll do this one for free." She closed the hatch of her Ion, and the duel began.

BT and Cooper immediately brought up their Vortex shield, as Slone unloaded her own Splitter Rifle at the Vanguard. As she was bombarding BT, two IMC Titans dropped in, a Scorch and Ronin. BT ran behind cover to a nearby crate. They needed a plan of action. BT placed Laser Tripwires just around the crate and waited. The Scorch Titan rushed their cover, slicing its legs of in the process. Cooper took BT a step back, shooting the Splitter into the hull of the Titan.

"Titan down. Two targets remaining."

The duo looked out of cover and fired BT's Laser Shot right into Slone's abdomen, shutting her down temporarily. She teleported out, but not before summoning a small squadron of Reapers.

"Let's see how you handle Reapers!"

BT ran down below the base of the gun, reloading the Splitter. The Ronin took this time to activate its Sword Core, and began to bash BT. Cooper dashed BT behind themselves to get more room, backing away from the waves of plasma fire. Cooper assessed the situation, looking around at the room, and informed BT of his improvised plan. "Follow my lead BT! Use the Laser shot for anyone I miss!"

"Acknowledged, Jack. Let's complete the mission."

Cooper directed BT out of cover, and charged right for the Ronin. They weaved left and right, dodging the slashes. When it made a bad move, Cooper grabbed the sword and quickly pried it out of the Ronin's hands. BT slashed bottom to top, effectively slicing the Ronin in half. They turned around as it fell apart. Reapers had taken different vantage points and rained down plasma at the two. They quickly made a break for the nearest one, stabbing it from the top. They grabbed its metallic husk and threw it at another two, causing a miniature explosion. They were well on their way to destroying all the Reapers when Slone's angry voice filled their radio.

"You can't outrun a Laser Core, you bugger!"

Out of seemingly nowhere, BT's Shields rapidly went away and his hull took massive damage. They sprinted for cover, but not before BT's automatic warning system triggered. They needed a new battery, and now. However, luck decided to shine on them today, but not with a battery.

"Laser Core ready. Battery required for hull damage. What will you do, Jack?" BT asked.

Jack tightened his grip on the controls. They had one shot to get this right. Once Slone was done firing, he maneuvered BT out of the barrier, and threw the Ronin's sword at the exposed abdomen of Slone. Her Titan staggered down to a kneel, and Cooper activated BT's Laser Core.

It absolutely ripped into Slone's Titan, reducing the shields and hull to zero in no time. She swore and shouted as BT and Cooper pushed her over to the edge of the platform. They pinned her with BT's foot, pointing the Splitter Rifle at the Ion.

"I'll never lose to a scummy pilot like you!" Slone yelled. Just before BT could pull the trigger, the PA voice announced, "Fold Weapon approaching Stage Four. Ring Momentum at 97 percent. All IMC Personnel evacuate now."

Quickly thinking, BT kicked Slone over the edge and into the abyss. They ran over to the weapon, and began prying at the machine. But it was too late, as the weapon activated, knocking BT's systems down. Cooper re-oriented himself, hearing Sarah's voice over the comms.

"BT?! Cooper?! Do you read?!"

"Cooper. The weapon's backlash has overloaded my critical systems. Attempting to reboot ocular system."

The OS that made up BT's screen began to boot back up. It better hurry! We don't have time! Cooper thought frantically. His worst fears arrived when BT detected a hostile Titan approach their visual range.

Blisk.

He jumped out of his Titan and right onto BT. Cooper shuddered in fear. But Blisk's face had no ill intentions. In fact, it looked more like subdued respect. His Aussie voice rang out into BT's audio systems.

"Lucky day for you pilot. I'm not going to kill you," Blisk chuckled, "But, you don't get to kill me either." He grabbed something from his front pocket, and dropped it. Cooper watch as the Apex Predators card fluttered down onto BT's optical. Blisk leaned down and patted it for reassurance. "You've earned this, eh?" He said, grinning as he walked.

BT and Cooper heard Marder try to convince Blisk to kill the two, but Blisk ignored this, simply stating "You should have put it in my contract. I've got other people with money to see." They watched as Blisk's Titan carried him into the cockpit and walk off. More of BT's systems began rebooting.

"My analysis indicates a throw is our only option here." BT said, his voice garbled.

Cooper saw the command of each system reroute power from auxiliary. While it did reboot most of the power, BT still needed help.

"Cooper, I require your assistance," BT aptly stated, "My auto-navigation systems are offline. You need to get me into that injector assembly. We need to do this, together."

Sarah suddenly was patched through their comms, though it was spotty.

"Boost… signal! BT! Co...per! Our gro… teams can't… make it in time! We n… you to somehow… destroy… inside! There's no… way!"

While Cooper made no sense of it, BT did. As he got BT up and moving, BT responded.

"Commander Briggs, I believe I have a solution. In its exposed state, my reactor core may be able to destabilize the Ark at the center of the Fold Weapon."

Jack stopped. Does this mean what I think it does? Sarah had an equal amount of confusion.

"What… saying, BT?"

"Commander, I'm gonna blow it up. I am sending you coordinates for a dropship rendezvous. Be prepared to pick us up."

Sarah sounded like she let out a sigh. "Coord… received. We… there, but I do… see how you can."

Jack didn't pick up the whole phrase, but knew what she meant. How the hell would BT get out of this? He continued to help BT into the Injector. BT said one of his many catchphrases that Jack had heard through their time together.

"Trust me. I have done the math."

Cooper sure as hell hoped he did. He could not lose his friend again. They were pushed into the Injector. Both pilot and Titan stared into the long tunnel of the gun- a light at the end of the tunnel for them. Cooper was really worried now.

"We got a way out of this one, BT?" He asked.

"Calculating." Was all BT replied. The gun prepared its firing process, and they saw the lights at the end blink on. The lights got closer and closer, and the Injector Fired.

In an instant they were launched at such a high velocity toward the Ark that Cooper had to grip the controls of BT. This is it buddy. Just you and me. We had a good run. But Cooper would not go out with BT.

"Protocol Three: Protect the Pilot."

What?!

BT's front hatch opened and BT pulled Jack out of himself, all while Cooper screamed to let go. BT ignored his pleas, and threw Jack away. He could only hopelessly look while his friend BT hurtled right into the Ark, causing a massive energy rupture that shook the planet to its core. Cooper landed on a piece of rubble that happened to float by after the explosion. Briggs spoke on the radio.

"Cooper, we just lost BT's signal! It's not too late for you! We're almost there!"

BT... Jack thought. But he couldn't think too long. The entire planet was about to explode. Sarah gave him more orders.

"Cooper - I'm marking your HUD with the rendezvous coordinates. We might have to pick you up in midair- there is nothing to land on out here!"

Cooper ran as fast as he could, jumping over floating chasm and onto boulder after boulder. Some debris floated up as a wall and he jumped onto the side, running across the wall. Even though he thought he had a stressful time, Militia Pilot Barker yelled, "I can barely move through this shit-show, Pilot! You'd better be there on time!"

100 meters to go.

Cooper frantically jumped from debris to debris, each almost conveniently placing itself in a position for him to maneuver. After running across one more rock, he landed on a metal panel, and sprinted toward the edge.

50 meters. Sarach confirmed his close proximity with "Cooper, Jump for it!"

He leapt as far as he could.

Jack saw the dropship fly in, Sarah reaching out. He was falling fast, and he reached his arms out so she could catch him. He was close to home. He could practically see the desperation on her face as he got closer and closer.

It would not be close enough.

As he got within feet of the dropship, a stray piece of debris struck him from the side, sending him flying right back into the unstable core. Sarah looked shocked, but Cooper reacted quickly, yelling "Get out of here!" over the comms. He didn't need more death on his hands. He watched as they flew off, sighing with relief they were safe. He was quickly reaching the core, signaled by the static filling his vision. He felt a massive vibration, and heard the explosion of the core as it went off. He closed his eyes, thinking one last thought.

Guess we'll be seeing each other again, BT.

The world filled with white, and Jack Cooper felt nothing, except the feeling of falling, and falling. The world went black.

And then he hit the floor with a massive thud.

Jolting awake, Cooper looked around. He was sore all over, and his head was groggy. His vision was obscured, so he sat up on the forest floor and started to look around.

Wait, forest floor? He wondered.

Cooper quickly shook his head around, making sure he was conscious. His sense of touch was not injured at all; he was in a forest. Lush trees surrounded him on all sides, and he heard the faint sound of a waterfall in the distance. He realized he needed to assess his situation before he could ponder how he got there.

So I've got most of my gear and armor, that's good. Cooper observed. He got the data knife out from its sheath, and also found in his holster the Smart Pistol. On his back holster he had his Hemlok rifle with a few mags in it. Jack got up fully from the ground, and noticed something.

He was in a crater, but not just his impact crater, as the mass necessary to create such a indent would have to be…

BT…

AN: Here is the first chapter of my new Titanfall 2/RWBY Crossover story, Fall in Remnant! I know it's a bit of a coldpost but I did check for most mistakes a few times. Anyway, leave a review and follow! I'll be out with the next chapter soon, hopefully!
