***ATTENTION***

This is the first part of an ongoing series I'm doing with Precursor1 called "In Perfect Harmony." Stay tuned here and on her profile for further chapters! The second one, titled "Making it to Tomorrow," is already posted, be sure to check it out!

Summary: Facing overwhelming odds alone, Jack and BT are sure to fall. It'd take a miracle to save them... or a really big robot.

Several times in my life I've wondered how I got to a particular point. When I learned that my real mother and father weren't the ones raising me, when I finally got to third base with my high school girlfriend, Taylor something I don't remember, when I first became an acting Pilot after dad died… And now, stuck in what looks to be my final fight against way too many goddamned Titans… Seriously how many do they have to send at us?! It seemed that no matter how many BT and I doomed, there was two more to replace the first. This was an honest to God no-win situation. BT's shield was long burnt out, we had structural damage all over the fucking place, and I'm pretty sure there's a spider crawling on my shoulder right n- Yep, there definitely is. Stuck in the middle of some fucking ravine with hundred foot walls, can only go forward or back, fighting for my life… How did I get here?

I'm not a praying man, but in this instance I couldn't help but wonder what awaited me on the other side, and counting all the things I'd probably never see again. My house on Harmony, our dog, the guys back home, my pain-in-the-ass sister Liera… Man, I really fucked up this time. Told her the IMC wasn't about to get me, that I'd be fighting by her side again soon enough. If I die she's gonna kill me…

Another explosion rocked the hull, and I snapped out of my daze. Now wasn't the time to give up, BT was still counting on me to take this as far as we could. I reloaded the Predator Cannon and set it to long range mode. The gun shield flickered to life as the Smart Core spun up, ripping the quickly closing Reapers to pieces and causing the nearby Ion Titan to go up in flames. Another down, only six hundred more to go... I knew the situation was bleak, but it hit me again just how fucked we were. Figured I almost might as well pack it in, when BT's robotic voice sounded out with the best news I'd heard all day.

"Pilot, we have friendly reinforcements inbound."

"BT unless it's like seventy more Titans, and right fucking now, it's not gonna matter!"

The thought nearly died in my throat as the ground shook as if the planet itself was cracking in half. The nearest Nuke Titan disappeared into the ground, swallowed by some unknown force. All was quiet for several moments, as none of the combatants knew what had just happened. The ground trembled again, and I could see the look of pure fear as an enemy pilot stared into BT's cockpit with a look devoid of all hope. He too was then gone, in the blink of an eye.

My mind became a whirlwind as hell itself seemingly sprung forth from the earth, engulfing three more Titans and forcing the remaining hostiles into a hasty retreat. The creature, whatever it was, was an all black snake-like thing that had appendages coming from a head of sorts, and inside that head was a core that looked very much like the reactor in a Titan. Its whole body looked to be covered in super-hardened armor - it seemed like even Titan weapons were worthless against it. If BT could've smiled, this would have been the time.

"Better than that, Pilot."

"BT are you sure that thing is on our side?!"

Liera's cocky voice was the first one I picked out after the ringing in my ears ceased, right after her airy laugh.

"What, Jack, did you think I'd just let you die? Get real, what'd I say about letting these dickheads kill you?! I need you to live now so I can kill you myself later!"

I've never been so happy to hear a threat against my life.

"Was wondering when you were gonna show up, kid. These schmucks caught me in the middle of helping an old lady cross the street, would you believe it?"

"Shocker. Let's teach these fuckers a lesson!"

"So sis, where'd you get the uhh… Giant murder robot? The one not named EV?"

"Murder now, talk later! EV, flame core!"

EV's robotic female voice sounded out.

"Engaging hostile Titans. Hello, BT-7274, Pilot Cooper."

BT responded in kind.

"Greetings, EV-5649, Pilot Lastimosa."

"Great to see you, EV! Let's kick some ass!"

The giant murder robot let out an ear-shattering roar and continued its rampage, gliding through the air - Liera had some real explaining to do - and swatting another two Titans with its monstrous frame. It set itself down on its three… tendrils? Yeah, sure. Set itself down and fired what I could only describe as a concentrated ray of death and fuck-you at a cluster of grunts and Stalkers, more or less obliterating them instantly. Mental note to not make Liera mad enough at me to warrant using this thing. BT charged forward, shoulder checking a Scorch and knocking it to the ground, where he then stuffed the Predator Cannon in the Titan's cockpit and fired for a few uninterrupted seconds. Satisfied that it was dead enough, I looked up and saw EV smashing the hell out of a Titan, ending its life.

The giant murder robot fired several explosive charges at a line of Titans, dooming them or otherwise rendering them incapacitated. Each of us went from one target to the next, picking off each enemy with ruthless precision. Not wanting to get too complacent, I set off for the next Titan. The Ronin I found charged at me, blade drawn. In a burst of nothing but adrenaline and possibly misplaced courage, I slid under the blade as it made a sweeping cut, punched out the legs, and dropped an elbow into the cockpit. Just then a Reaper jumped on BT's back, firing close range shots into him, so I quickly rolled hard on the ground. Luckily this was enough to dislodge the damn thing, so I then grabbed it by the torso and legs and literally ripped it in half.

Discarding the remains, I looked around again. I saw EV in the distance picking up a doomed Titan and tossing it into the air, only for it to be intercepted by the murder bot, which hit it with a focused laser and sent it careening into a cliff and exploding. I could hear Liera growl at that, and EV then moved to dispatch several Reapers, snatching them right off the ground and throwing them like baseballs. Liera yelled into the comm.

"Batter up!"

The murder bot came back around and smashed each Reaper with its tendrils, sending them to pieces immediately upon contact. I smiled and shook my head at Liera's antics, always the drama queen.

"Pilot, recommend you focus on the remaining hostiles."

BT's warning caused me to shake my head once again. I glanced back at the field in front of me. Still not out of the woods, gotta keep focused.

"Hey Liera, toss me one!"

Without missing a beat EV threw a hapless Reaper in our direction. I loaded up the power shot, took aim, and fired, destroying the damn thing mid-air.

"Whoo, hot damn! Thanks sis!"

I saw EV flash a thumbs up, before curling the same hand into a fist, swiveling around, and belting a Northstar Titan in the face. I then caught sight of another Scorch heading our way, so I switched the Predator Cannon back to close range mode and began laying into it. It sent its Firewall at me, hitting BT in the shoulder bracing the gun. BT stumbled, nearly losing his balance.

"Pilot, significant structural damage sustained. We must end this now."

"Roger that buddy, let's waste this fucker!"

I used BT's dashes to quickly close the gap, using large rocks as cover. Once we were maybe fifty feet away, it launched a shot from the Thermite Launcher right at us. With a surprising amount of agility, and probably some dumb luck, we were able to sidestep just enough to watch the column of fire sail past us, seemingly in slow motion, missing us by mere inches. We looked back at the Scorch, letting it know they were fucked. The enemy Titan frantically tried to reload as BT charged again, Predator Cannon at the ready. Using the Cannon, he flipped the Scorch up into the air, impaled the Titan on the barrel, and fired until the magazine was empty. When the ammo count ran dry, BT threw what was left to the side.

"You sons of bitches started this, we're gonna end it! Which one of you bastards is next?!"

After several minutes of carnage that even dad would be proud of, everything was more or less over. BT finished ripping the battery out of the last Titan, as I caught sight of EV stomping out the last foot soldier. I was breathing very heavily, sucking in air by the bunch. I could her Liera doing the same over the comm. The murder bot landed with another giant thud, shaking everything around it. Maybe twenty feet from me, it was easily the single most imposing looking creature I'd ever seen at a few hundred feet tall. It eyed me down, electricity rolling off its body all the while. Each of the links of its body seemed to move and reset, making it seem even more terrifying somehow. Liera got my attention with her bombastic yelling.

"Yeah baby! That's what I'm talking about! Been a while since I've gotten that excited during a fight. How about you, Jack, was it as good for you as it was for me?"

"You're hilarious. Now, what uhh… what the hell is that?"

"Called an Architect. You like?"

"So long as it doesn't decide I'm on the menu, yeah I suppose. You got a name for it?"

"Not just yet, but I'm thinking Tiny."

"Somehow I'm not surprised. It's acting like your pet or something, what's the deal with that?"

"Long story short I can control it with a mental link not unlike how we use our Titans. There's a lot of science bullshit besides that, which I don't really understand, so don't ask."

"But how does your brain not explode from all the mental stimuli? Just pairing with a Titan takes some serious juice! I can't imagine what kind of supercomputer you'd need to control that thing."

"What did I just say, Jack?"

"...Noted. So where'd it come from?"

"Found it."

"...That's it?"

"Yup. Come on, let's get out of here."

She punctuated the statement by walking away, signaling for me to follow. I shrugged, figured it probably wasn't worth the effort to pull the whole story out of her, and accepted the fact that I was just saved from a fucked situation in miracle fashion by my kid sister and her new world eater. Just another day, right? I jogged a bit to catch up to her.

"So, what're we doing tomorrow?"

A/N: So this was my first ever story, written in like an hour based off an idea that came to me during a discussion with Precursor1. If you haven't seen it already, check out her story 'Of Steel and Stardust,' which is a crossover between Fallout and Titanfall. It is without a doubt one of the best fanfics I've ever read. Plus, she gave me permission to use her OCs from that story in this one, so thank you to her for that.

Finally, a big thank you to whoever read this and got all the way here, you're wonderful. All the best!
