AN:Soooo! I wanted to make a HaloxRWBY story that involves only two Spartans and their escapades through Remnant with no extra plots aside from the RWBY one and how they can adapt to it! Do enjoy the product that came out of that crazy idea! I own neither RWBY nor Halo, or the characters presented in the story as is. Halo belongs to 343 Industries and Microsoft and RWBY belongs to Rooster Teeth.


Multiverses are such a... Fickle... Thing... In one universe, two warrior heroes stood face-to-face with their inevitable demises. They fought bravely against foes too dark to comprehend at first, or against those that burned their homes for many years, those that took family and friends away from them without hesitation. They stood their ground and fought to their last dying breath.

Now, one floats aimlessly through the void, while another rests in the glass and sands of the planet he fell to defend. Their stories intertwined once, when one saved the other from demise, granting humanity a victory well-needed. Their stories will meet again now... And they will depend upon each-other to survive a hostile environment and a world on the brink of War...

So join me, as I tell the story of two Hyper-Lethal Vectors that may otherwise have never met, had fate and a little magic not decided to unite them.

ABOVE UNKNOWN PLANET, EARLY 2553.

UNSC FORWARD UNTO DAWN AFT SECTION:CRYOBAY

... The feeling of warmth that the hulking armored man in the cryogenics tube felt in his chest was his blood beginning to pump normally again. Master Chief Petty Officer John-117 was not sure for how long he had been asleep, but his eyes slowly opened as the condensation on his Visor cleared. His Heads-Up Display booted up and soon, his helmet's sensors picked up increased noise. The shrill wail of proximity alarms soon came to his ears. His combat senses kicked in. Using his two hands, he pushed the top of the cryo-casket open, before jumping to his feet and grabbing his MA5 Rifle from the side.

He looked to the pedestal in the center of the Cryo-Room, to see the small, blue avatar of a short-haired beauty running diagnostics over multiple ship systems... At least from the section they were in. Chief looked to her, then spoke "Cortana, Status report." and he saw her gaze suddenly shift to him. With a smile, she nodded...

"Good to see you're awake, John... We've got several problems, it'd seem... Sleep well?" She smirked.

"Considering..." John shrugged. "What problems?"

"IFF Tag's telling me there's UNSC Personnel aboard and it looks as if we're about to crash onto a planet, John." The woman said "Yank me. I can tell you more on the way to the Cargo Hold." to which John nodded, removing the chip from the pillar and sliding it into his helmet's port. The Spartan dashed one of the darkened, scarlet-lit corridors of the destroyed warship...

"You said we're going to hit a planet..." John hummed. Something felt off. "Where're we landing?"

"Somewhere in the wilderness, if my calculations are correct... Though I'd advise against letting the ship land anywhere." The AI spoke... "Take a right. We're gonna meet our contact just around the corn-" And she stopped as Chief swiveled about and brought his rifle up, only to be greeted by a Designated Marksman Rifle's barrel. A soldier in black SCOUT Armor, netting and everything, appeared, rifle shouldered.

A Spartan... ID Tag B312. The two soldiers immediately lowered their weapons and B312 brought his hand up in a salute. John gave a salute back, before waving the soldier forward, wordlessly. He nodded, tailing behind the Chief as they moved toward the Cargo Hold. John raised three fingers. 312 answered with a quick nod, forming up right beside the Chief. He spoke calmly "What's going on, sir?"

"We're entering the atmosphere of a planet soon." John explained. "Cortana, what's our plan?"

"There's a Pelican in the Cargo Hold. We're taking it and jumping ship before it crash-lands. I've managed to get proper scans of the planet... And she's gonna crash into the Ocean, Chief." The AI spoke over com, before saying calmly "Good to see you again, Noble Six... Been a while since our little trip to the Autumn. You'll need to help fill John in on the situation."

"I'll take your word for it, Ma'am..." Six figured this must've been the AI he escorted. He needed more time to process what had happened to him, but he'd take finding a fellow Spartan over more Covenant every day...

The Chief stopped in front of the door to an elevator...

"Watch out when you open it. That section's not pressurized." Cortana warned. John's response was to immediately seal the suit air-tight. Six did the same... And the two Spartans kicked in the door. A gust of wind erupted around them as the hold depressurized. The two Spartans jumped down the shaft, powering their armor thrusters only to touch down safely near the Cargo Hold. Powering the Flashlights on their weapons meant the high-intensity beams cut clean through the poorly-lit darkness. They scanned the walls as they walked inside, looking for the Pelican.

"John, may I suggest something?" Cortana spoke calmly.

"Shoot." The Chief spoke, stopping his sweep as he saw the back landing strut of the Pelican and the nagging feeling of wrongness still at the back of his head. He and Six nodded to each-other and proceeded to advance toward it. The ship shook and rattled, its hull groaning under the stress... He looked around and, without Cortana saying another word, he saw a Manifest pop up on his HUD, with the focused item being a HAVOK Warhead... Military-grade, of course. Good plan. Destroy the ship before it crash-lands...

The Chief tilted his head toward the box containing the HAVOK Nuke. The Spartan-III gave a nod back in response, slinging his DMR onto his back and moving toward the leaded container, kneeling beside it, inputting the code... The box clicked four times and slid open, steam escaping it. The Chief, meanwhile, jumped aboard the Pelican, slotting Cortana into the chip feed and sitting himself down in the pilot's seat. Tapping a few lines of code, as well as commands into the system, the Spartan staggered as the ship shook and groaned again.

Cortana smirked as she powered the systems, then said "Six set up the HAVOK to detonate in one minute."

"That enough time?" John asked.

"Should be just enough." She nodded. Chief looked back and saw the enigmatic black-armored soldier step inside, giving a nod to him, before sitting down in the Blood Tray. The AI spoke with a half-grin "We're ready for takeoff... John, give me the stick for a bit." to which he agreed wordlessly, watching as the back hatch of the Aircraft closed. They felt the ship shudder, its engines thundering as they heated up and came to life.

30 seconds had elapsed already...

"Taking off." Cortana said "Taking gun control... I'm gonna burn a hole through the wall of the ship using our missiles and ammo. Hang on to your helmets!"

20 seconds left...

The rumbling noise intensified and John saw the Titanium-A wall ahead spark and explode. The nose-mounted 30mm Gatling Gun punched through it, using Armor Piercing rounds. Cortana hovered her 'hand' over the Rocket Pods, waiting for a time where the wall would be weak enough to punch through, before muttering "15, 14, 13..." and... Firing. A dozen missiles screamed from their wing mounts, striking the wall and drilling a nicely-sized hole into all of its layers... Air hissed as objects began to be sucked out... But soon, as the smoke cleared, they could see the planet...

5...

4...

Cortana boosted the engines to maximum...

3...

2...

The aircraft burst through the opening and arched down, its engines entering maximum thrust and beginning to overheat... John and Six hanged onto their seats tightly, waiting for it... And finally, as the nuke counter clicked 1... And then zero... A bright flash enveloped the starlit background and a wave of radiation and heat passed the vehicle, pushing it into Mach speeds. Its engines died, as did most of its electronics. Only Cortana's pedestal and Life Support were shielded...

"Dammit! The nuke EMP'd us!" Cortana balked "We don't have engines, but I do have Hydraulics control! I'll try to smooth our descent as much as possible, but I can't promise we won't hit the ground like a meteor at this point. I'm working on"

"Hang on!" Chief yelled back.

"Already doing so!" Six answered, sliding the safety harness over himself... John was a bit too big for the Pelican's seatbelt to wrap around him, so he did his best, hanging onto the consoles as the Aircraft dived toward the planet below. Wisps of fire soon formed into a cone at the nose of the ship. The heat from re-entry poured through the ship's hull and the two Spartans felt their skin prickled by the fire...

They were going at around Mach-3 thanks to the explosion. If they didn't manage to slow down...

Cortana managed to power on the ship Console. John saw it had a bit more juice and it didn't short out as its blue-hued screen came online. And two counters pinged onto the screen. The aircraft was dropping altitude fast on the first counter. The second one was seconds before Cortana could power their thrusters... It looked narrower and narrower to the Chief as the aircraft fell through the unknown planet's skies like a boulder. His grip tightened enough to bend the metal alloy...

"Almost got the Engines back!" Cortana stated "Just hang in there!"

The aircraft breached the cloud layer and turbulence started to intensify enough that whatever was in the netting above the seats fell to the floor of the Pelican and then proceeded to slam into the back hatch, thanks to gravity. John himself was pinned to his chair thanks to the ever-growing negative Gs the aircraft pulled in its annoyingly steep descent... He barely managed to glance out of the window to his left, to look at the engine nacelles vectoring, turning downward, as his blood rushed to the back of his skull... He saw the ground approaching afterward...

And the sudden jolt of deceleration made him slam into the metallic console ahead. It cracked and sparked. His shields flared, but remained active. He then found himself slammed forward again as the aircraft's engines stressed and barked, before he managed to look up... And see the ground still approaching, except not straight toward him... They were almost parallel... The aircraft rammed into the ground, bouncing up as one of its engine nacelles and the left landing gear fell off. It skidded, digging a deep trench into the ground, before grinding to a halt just centimeters short of the edge of a cliff... The moon hanged lazily over the sea below said cliff...

Inside the aircraft, the Chief slowly stumbled to his feet. He yanked Cortana's chip from the Holo-pedestal, slid it into his helmet, then stood up. The AI chuckled, then said "This was one of our better landings..." as the Spartan turned to gaze at their passenger... He saw that the harness that held the man down, as well as the back door, had been ripped clean off. The door was dented from the inside out as if something had impacted it... And John could see, in the waking trench left by their crash, the Spartan, his armor, dirty, but now unlocked, slowly staggering to his feet.

The Chief grabbed his Assault Rifle off the floor, slid it onto his back, then walked toward Six as the III dusted himself off. He shook off the dust and whatever concussion he may've had, then looked up to the Chief and gave his okay. He looked to his shoulder and flicked off a stone, before saying "Forgive the brashness, sir, but that landing was... Not the best I've had." before looking around "But not the worst, either..."

Chief gave him a nod. "Ever fall from Orbit?"

"Yessir." Six nodded.

"Let that be the worst you've had." John simply stated. He motioned to the bird. They still had gear to unpack... The Lieutenant moved toward it, with the Chief. The two stripped whatever they could out of the aircraft, ranging from Rifle Ammo to a pair of Battle Rifles and M6 Magnums, as well as ammo for them. The Lieutenant paused once he saw the Chief grab a HAVOK Tactical Warhead... One out of three... From the aircraft. He stowed it on his bottom mount, then took the other two and put one on his left thigh, tossing the second to the Lieutenant.

He nodded, slung it onto his armor's bottom mount too and drew his DMR. The two walked away from the vehicle with around three duffel bags of ammo as well. Cortana'd been very quiet during the Spartans' little scavenging trip... Now she piped up "Be advised:I'm detecting multiple unknowns converging on our position... And judging by their advance pattern, we're probably facing enemies. Unknown types and unknown numbers... Approaching from the thicket ahead."

John noticed the forest and shrubs surrounding their crash site... They must've aggravated something nearby...

He looked to Six as the man drew his Assault Rifle, an MA37K Model AR usually used by the Army. He took a knee, shouldered his rifle and racked the bolt, taking the safety off. John followed, taking his MA5 and kneeling. They covered 180 degrees. Both knew their arcs of fire... Both would kill what came after them. Just as they finished preparing their lines of fire... The first creature emerged.

Black as the night they found themselves with, with manes of shadow and armor of carved bone, with grotesque spikes sticking out of their backs and bodies seemingly mutilated as if they were some kind of experiment gone horribly wrong, monsters of the Night resembling of tall, lanky wolves, short, stout and buff two-legged Lizards and even a trio of giant porcupine-like bears charged into the clearing...

Chief and Six exchanged a glance with one-another, though their heads didn't move. The two Spartans were as cohesive as could be. And that showed. The moment John pressed the trigger, the rattle of two Assault Rifles erupted instead of only one. In a sweeping barrage of 7,62 AP Ammunition, a dozen of the smaller creatures were cut down. The Spartans reloaded one after the other and continued pouring lead down range. More smaller creatures died in the hellfire...

John watched as the tall, lanky wolves approached on all fours at breakneck speed, closing the gap between them. At least a dozen of them. And they were wasting their ammo on the small-fries. Small-fries that kept getting closer too... Chief looked to Six, slung his weapon onto his back and withdrew his oversized Bowie Knife from its belt-mount, as well as his M6 Magnum.

He roundhouse kicked one of the wolves down, before plunging his knife upon its unarmored throat, slitting it. Black smoke left the gaping wound as the Spartan fired his pistol into the crowd of monsters coming at them. Thunder cracked and a pump was heard. John turned to see Six with a shotgun in hand, dancing a ballet of death as he spun the pump-action weapon 'round and 'round, nailing enemy after enemy with pellets, while kicking, punching and stabbing.

Whilst he fought, using legwork, he reloaded his Shotgun after a full tube had been spent, before racking the bolt, turning it around and slamming the stock into one of the wolves. He shoved the barrel into the thing's mouth and fired off a blast that splattered bone plate onto the floor. The corpses, the two now noticed, began to dissolve... Cortana hummed as she looked over sensor scans from Chief's armor "Curious... See if you can't retrieve a piece off one of these things for later analysis."

"Kind of..." John grunted, kicking down a creature before stomping on its head and stabbing a third through the head "Busy at the moment."

He heard the hiss of claws moving through air and his hand moved up to intercept the claws and paw of the Wolf on his left flank. The Spartan proceeded to drop his knife, toss his pistol into the air, catch the knife and stab the monster in the face with it, before leaving the knife, grabbing the gun and firing two shots into its chest. Shots that would later punch through another two wolves.

He grabbed his Knife from its now-dissolving face, before plunging it into the giant bear-like monstrosity that now attacked him. It pushed into him, kicking up dirt and dust. The Chief quickly offed it with a kick to the top of the head which plunged the knife into its bone plate. He grabbed the Knife and threw it, nailing a lizard that was about to pounce on Six to the floor. The Spartan-III gave his II Counterpart a nod in thanks, before firing his shotgun into the belly of one of the two remaining bears. It collapsed, beginning to dissolve as Six raised his shotgun to block the strike from another claw... The shotgun buckled and broke in half at the center and the claw nicked his shields, but the Spartan managed to back off and draw his sidearm in time... The monster died with five shots center-mass.

Two scarlet-shining explosive projectiles flew into the mass of skittering monsters and detonated, splattering them across. The hiss of a large blade cutting through the air followed. A blur of scarlet rose petals came into view and several monsters lost their heads. A strand of white hair in a mass of the smaller ones ended with sharp ice projectiles nailing multiple monsters to the floor. And then, a blur of inky blackness was followed by blades of a deep purple color slashing more monsters apart. Cortana snorted "New contacts incoming. Human."

A blonde-haired beauty with lilac eyes jumped into the center... She wore a tan jacket that bared her midriff, with golden brown piping and short, puffy sleeves with black cuffs that featured two gold buttons. Underneath this, she wore a low cut yellow crop top with a burning rose on the left, drawn in black. She also wore a brown belt covered by a pleated brown piece of material reaching from hip to hip around the back of her waist, with her emblem emblazoned on the right-most pleat in gold.

Underneath this was a long, white, asymmetrical piece of material reaching to her knee on the right side, as well as a pair of black mini-shorts. She wore a pair of brown, knee-high boots and orange over-the-knee socks, with the right sock pushed down just below the knee. A gray bandanna was tied around her left knee and an orange infinity scarf and black fingerless gloves completed her outfit. A pair of golden gauntlets with barrels and shotgun shell straps wrapped around the gloves.

Following her was a girl with black, short hair and red highlights, as well as a pair of silver eyes. She wielded a massive scarlet scythe that looked like it'd been merged with a Sniper Rifle of the 50 and above Caliber variety. She wore a black dress with her waist wrapped in a corset that had red laces. A belt hanged around the strange, puffy black and red skirt as well, with ammunition and a belt of silver bullets on it. Below that were dark-red leggings and a pair of black and red boots to complete the lineup.

Then, there was an almost entirely white woman with white hair caught in a side ponytail by a tiara, deep blue eyes, a scar over her left eye, a skirt and dress similar to the red girl, a jacket with frills at the wrist-cuffs and a Snowflake emblem on the back. She wielded a Rapier/revolver combo and had the stance of a trained fighter, not too far apart from the other two.

And the last one in was a black-haired beauty with amber eyes, a bow on top of her head, a white shirt underneath a... strange black garm, short white sweatpants linked to a pair of leggings that went from black to lilac and an emblem on them as well. She also had black sleeves locked onto her hands by metal bands and a strange wrap around her right arm. She wielded two blades, one of which seemed to also turn into a handgun.

Chief squinted, noticing they took a circular formation around them... The red-haired girl turned her head and smiled, a glimmer of excitement in her eyes. The Spartans joined the formation, mingling in-between the girls and keeping their weapons trained on the creatures ahead. The white one spoke, a hint of worry audible in her voice "Ruby. There's too many of them. I'd suggest we head for the Bullhead with our two..." She glanced to the Spartans "Guests."

"Pfft, c'mon, Weiss, live a little." The blonde one snorted, bouncing from one foot to the other while beaming with excitement.

"I agree with her. We can fight and fall back..." The black-haired one stated simply... "Can't risk ourselves and these two."

The two girls wanted to respond, but a gunshot rang out. One of the Lizards dropped to the floor, missing its forehead. John's gun barrel smoked as he dropped the empty magazine and loaded in a fresh one, before stowing the pistol and readying his knife. For now, the little things didn't impress him. He heard the thunder of a DMR and saw Six poising himself to strike at the creatures too, with two already dead and a bayonet fixed to the end of his rifle... But he was ready to go just as much as John was. Spartans didn't run from a fight, but they didn't waste time either... Whoever had sent these four teenagers to get them clearly wanted them wherever they were...

Six tilted his head to an open route and John nodded... "I'd suggest we leave too. I don't want to waste ammo."

The red girl turned toward the Chief, then said "Alright." with a nod and smile "Let's go, girls!"

And the group beat the retreat, firing as they went. The red girl had barely caught up to the Chief and Six, to point to a landed, round VTOL Aircraft and yell out "There! That's our way out!" as she panted. The Spartans slowed down, to keep pace with the girls, their guns still barking as they went. The group jumped onto the vehicle's open side and climbed aboard and John knocked on the Pilot's door twice. The universal sign for 'all aboard, take off'. The engines of the aircraft vectored and powered, before lifting the vehicle off the ground, with the horde of approaching monsters not too far behind.

The Chief looked to Six, pointed at the Pelican getting swarmed, then at a stock and pair of tubes in the duffel bag. Six nodded, walked up to the weapon, grabbed it, loaded it, then approached the side. The girls' eyes went wide and the blond even called out "W-wait, what are you guys-!"

"Backblast, Clear!" Noble Six called out, locking onto the Pelican and... Firing. A gust of wind kicked up and partly dented the roof of the aircraft and a contrail of smoke followed the missile that left the barrel. It arched through the air, before it struck true, into the fuel reserves of the otherwise-empty Pelican... And the ensuing fireball engulfed quite a few creatures around it.

The two Spartans exchanged glances, then nodded to each-other, while the girls behind them coughed out smoke... A lot of explanations were due, both from them and from the girls. Cortana hummed, then said "John, I think we may need to prep for a long series of questions. We're heading for what seems to be a city of sorts... Right for the center of it."

... Great...
