Notes: Oh this has been a long time coming. I have always been a big fan of the Halo series and knew I wanted to make a story with it but. The halo story can be a bit too series for my writing style and I like have a wide range of characters to pull from so I thought why not make a crossover. I wasn't sure how well these two series would fit together but I was pleasantly surprised that it was fairly easy write. I plan for this to me a short series since I have so many other projects going on right now but who knows how things will turn out.

I hope you will enjoy this work and as always I would love to hear all your thoughts and feedback on it so far. And of course if you like this and haven't already why not check out some of my other RWBY works I have quite a few.


Planet Remnant

Year 2557 - four years after halo event.

That which was once a proud UNSC combat vessel known as the Forward onto Dawn was now little more than a heap of gutted wreckage floating aimlessly through the vast emptiness space. From the outside the ship would seem completely devoid of life, just a hollow shell of what it used to be. And if left undisturbed that's likely how it would have stayed. However looks can be deceiving and fate has a bad habit of throwing curve balls whenever it sees fit. And one such curve ball came in the form of a rip in the space near the forward onto dawn. The rip was a slipsace opening created by a small vessel that soon emerged from it.

Aboard the new ship a computer terminal flickered on to display the image of a small girl with short red hair, green eyes, and freckles. "Slipspace jump completed, the target has been located, and all systems operating normally. I am awaiting further instruction Captain!" The girl said while giving a salute to another girl seated in front of the monitor. This girl was dressed in a red cloak and a similarly colored suit of power armor. The armor covered her from head to toe obscuring all other features.

"Thanks Penny, that will be all for now." The red armored girl responded before she turned towards another slightly taller woman in bright yellow armor. "So what do you think Yang?"

The yellow armored woman known as Yang gazed out of the reinforced glass window of their cockpit to see the ship before them. "What's there to think? I mean wow, that's seriously the UNSC Forward onto Dawn! I heard it was a big ship but dang, it's just so huge! Who would have thought that this was the source of that distress beacon. What a lucky break, this is going to be a sweet score for sure. I mean these military ships almost always have some real goodies to be found. And it looks like we may be the first pickers." The woman responded excitedly.

"I don't know Yang, this seems sketchy." The cloaked girl said worriedly.

That's when another girl in white armor turned around in her seat to face them. "That's putting it mildly. Remember the last time it seemed too good to be true? Guess what, it was and we almost got killed! How did a UNSC ship of that size even end up out here in such a condition? Last I checked those types of ships are usually either on the front lines or guarding major planets not out here in the sticks." She warned.

"Why are you always so pessimistic Weiss? Maybe it was a slipspace malfunction or something, you thought about that? I mean we see that sort of thing all the time. The point is that we could sit here and debate all day but we will never know for sure if we don't go down there and check things out." Yang retorted.

It was then that the last member of their group which was currently sporting black armor with set of horn like helmet extensions decided to finally join the conversation. "She has a point Weiss. We won't learn anything if we don't even go inside. And we can't just go back empty handed after coming all this way."

"Et tu Blake, et tu?" The white armored girl known as Weiss retorted dryly.

The black armed girl known as Blake just shrugged before turning towards their red clad captain. "You're the leader Ruby so it's your call. What should we do?"

Though Ruby's face was masked by her helmet through body language along it was clear she was deep in thought. She remained silent for a moment before she reached behind her seat to grab hold of what appeared to be large rifle of some kind and promptly strapped it to her back. "Well you know what they say. Nothing ventured, nothing gained! Alright team RWBY lets get in there and see what we can find!" The girl declared cheerfully.

"Yeah I love it when you get feisty sis!" Yang cheered.

The Weiss just let out a loud sigh before pulling out a silver rapier and attaching it to her side. "Fine, however let it be known that I reserve the right to say I told you so."

"Fine whatever Weiss." Ruby huffed while turning back to the monitor. "Penny, pull us in close to dock and then copy yourself over to my suit."

"Roger that Ruby!" The freckled girl responded before the ship began to snake its way around the floating debris littering the area around the Forward onto Dawn and heading towards an opening in the side of the UNSC ship. Once the small ship made it inside it quickly set itself down and deployed landing gear to magnetically lock it in place. Then the girl known as Penny once again appeared on the display before beginning to flicker wildly and splitting in two. One of the fragments vanished as a chip was ejected from the terminal. "Coping complete, now remember not to lose me Ruby. Even though it is only a fragment it will be bad news if anyone gets a hold of it. I don't want father getting angry with us, again."

"Don't worry Penny I always handle with care." Ruby responded in a teasing tone. Then she quickly extracted the chip and plugged it into a port on the back of her helmet. With that task done she turned back towards her teammates to address them. "Alright move out team!"

Without further ado Ruby and her team disembark form their ship and began floating their way through the halls of the UNSC ship in search of supplies. They were taking their time with the affair so that they wouldn't miss anything worth taking and so they would be ready for any possible threats that might pop out at them.

"Man, this whole no gravity thing sucks!" Yang complained before turning towards their leader. "Why don't we plug Penny in and see if she could get it back online." She suggested.

This suggestion caused Yang's teammates to roll their eyes. Yang was always the most gung ho about these types of missions but was also usually the first to complain when things got dull. Of course Yang's teammates were all quite use to her contradictive behavior at this point so it didn't really matter much.

After turning the next corner Ruby spotted what seemed to be an undamaged terminal in an open room at the end of the hall. She promptly kicked off the corner wall to float down the hallway and out into the room and her teammates quickly followed suit. "Hold up guys, I will see if I can get the gravity back on." Ruby said as she pulled the chip carrying the Penny AI out of the back of her helmet and plugged it into an available port on the terminal.

Meanwhile Weiss grabbed onto a wall railing to stabilize herself before turning towards Yang to speak to her. "Gees, do you feel the need to complain about every little thing Yang? I mean really we have been here for what, a few minutes maybe?"

"Hey lay off, I just don't like zero gravity okay! Hand to hand combat isn't very effective if there is no weight behind your blows and besides I…" Yang trailed off as her eyes and helmet tilted upward toward the ceiling. "Oh sweet, dibs!" She declared when she spotted a Battle Rifle floating above her head near the ceiling of the room. Weiss just shook her head as Yang began wiggled around helplessly trying to reach weapon before finally realizing she needed to fire her off her suits built in thrusters to gain momentum. She lightly tapped a button on her wrist causing a small sputter from the thrusters allowing her to float up towards the rifle. "Alright come to momma!" She said as she reached out rapped her arms rapped around the weapon. The moment she did the gravity in the room suddenly kicked back on catching her off guard and causing her to plummet down to the floor landing on her ass hard enough to cause her shields to flare. And a moment later the gun fell onto of her head with a thud causing her yelp and grasp at her head in pain. "Ouch! What the hell was that Ruby, bad timing much!?" She roared angrily.

Ruby looked back at her with a slightly panicked expression hidden behind her helmet. "Umm guys I didn't do that!"

Then Penny's image appeared above the terminal. "Captain Ruby I have just picked up the activity of another AI in this mainframe! It would seem that we're not alone on this ship."

A siren now blares throughout the halls of the Forward onto Dawn. Its purpose was to notify the crew of the ship that there were currently intruders on board. A single terminal in the center of the cryogenic chamber is all that responds. It pulses with energy before the image of a purple female AI appears above it. The AI seems panicked and almost unsure how to respond. She presses a few buttons on the digital interface in front of her before turning to face a cryo-pod directly behind her. "Wake up Chief, I need you." When she says this the cryo-pod begins release jets of steam as it starts to thaw out. As the steam and ice dissipate a large figure inside the pod is revealed. The figure is covered in green power armor that was riddled with battle scares and plasma burns.

A moment later a groan could be heard from the large figure in the pod as it began to stir. The voice was deep and undeniably male. "Chief! Easy, you have been out for a while." The AI hisses at the man in the pod.

The man seemed confused and disorientated as he began looking around the room through the glass window of the cryo-pod. It was clear he was trying to figure out his current location and how he came to be there. After a moment of this without anything coming to him he finally gave up responded to the AI. "Where are we?" He asked as he started pounding on the glass blocking him from exiting the pod.

"We are still adrift on the Dawn." The AI responds.

"Why did you wake me?" The man asked.

"Just hang on I'm bringing your systems online now." The AI told him while pressing more buttons on the digital control panel in front of her. The man shifts around impatiently in his pod while his power armor begins to power up. "I rewrote your suit's firmware while you were out." She continues.

"You have been busy." The man says while his helmets heads up display flickers to life.

"Yeah and now I'm activating the ship's gravity generators." The AI states before all the floating objects around the room come crashing down to the ground when gravities pull comes into effect. "Now Chief I need you to look up. That's the manual release for your pod I will need you to pull that." She tells the man.

Following the AI's instruction the man quickly reaches up and slams on the release popping up the glass panel in front of him and allowing him to step out into the room. "Seems like old times." The AI says as the man makes his way over to her terminal.

"You ready to get back to work?" The man inquires.

"And here I was thinking you would never ask." The AI says teasingly.

The man almost chuckles before pulling a data chip out of the terminal and plugging it into a port on the back of his helmet. Then he pulled out and readied an assault rife he still had on hand from before he got put under. Pleased that the weapon still seemed to be in working order he figured it was time to get down to business. "Alright, what are my marching orders Cortana?"

"We've got intrusion alerts lighting up on multiple decks. Our best bet for figuring out who's boarding us is the observation deck four floors up." The AI known as Cortana explains.

"Could it be a rescue team?" The man inquires.

"They don't seem hostile…yet. So I can't rule out the possibility, however I am not picking up any UNSC signatures in the area so we will have to proceed with caution alright Chief." Cortana tells him.

"Roger that Cortana."


"I told you so." Weiss said dryly while releasing another sigh.

"Save it ice queen, we still don't even know if this AI is friendly or not. Besides it could be all alone and in need of our help." Yang barked.

"That is unlikely Miss Xiao Long. UNSC AI have always been strictly controlled in order to make sure they wouldn't fall into enemy hands. The likelihood of one being found alone and undefended is slim to none. Besides the other AI's most resent activity shows that it has thawed out a cryo-pod before activating the gravity systems. If it was alone there would be no reason for such actions." Penny interjected.

"Well that's just great! So what's the plan sis?" Yang inquired as she turned to face Ruby.

Ruby placed a hand on her chin and began to hum to herself in thought again. "Well if I was them I would probably be heading for the observation deck to get a better view of the situation. So if we want to get to the bottom of this that's where we need to be heading as well." She told her team before she removed Penny from the terminal and slotted her chip back into her suits helmet.

"Wait we are heading towards them?! Shouldn't we be trying to avoid unnecessary contact?" Weiss interjected.

"Weiss it's like Yang said. We don't know if they are hostile or not. They could be stranded here and in need of our help. We can't just leave without knowing anything." Ruby reasoned.

"Besides even if they are hostile I'm sure we can take them!" Yang declared while cracking her knuckles. "Isn't that right Blake?" Yang asked the empty space where her black clad teammate should have been. "Umm, Blake where did you go?" Yang asked while looking back and forth for her friend. "Hey have any of you guys seen Blake?"

A sense of panic soon came over the three of them as they realized they were one pointy head short. Ruby quickly pressed a hand to the side of her helmet and began to speak into its built in radio. "Blake, come in! What is your location?! Do you read me?!"

A moment later a burst of static came through the ear piece and the static was mixed with broken words. "I am hav… tr… ble… hearing…ust be som… inter… I am… in… library!" The radio then completely cut out but the last word came in just clear enough for everyone to understand what had happened.

A yellow armored hand promptly came up to palm the face of its own. "Leave it to Blake to pull something like this. Really, I should have known would happen. I seen her get that glint in her eyes when we seen the map of the ship a little ways back. That girl just loves books, a little too much some times." Yang stated.

"Well nothing we can do about it now but go and get her! Penny, where is the library's location?!" Ruby shouted into her helmet.

"Sending coordinates to your heads up display now Ruby!" Penny said enthusiastically.

As the coordinates came in Ruby's face twisted in disbelief. "For the love of $%#^%!"

"Sis what's wrong!?" Yang inquired in a worried tone. Clearly not use to her sister using such colorful language.

"Guess what's between us and the library?" Ruby asked he team.

"Let me guess, based on our luck so far it could only be the observation deck. Am I right?" Weiss asked.

Ruby only nodded her head before she pulled out her weapon from behind her back and cocked it. "We have to hurry. If they are an enemy Blake will be in big trouble!"

Both Weiss and Yang nodded in understanding and promptly drew and ready their own weapons. "Yes Captain!" They both said in sync.

"Alright let's go and get our…. AHHHH!" Ruby began before a surge of bright energy shot through the ship causing all the panels and monitors around them to sputter, flicker, and hiss wildly.

"Penny what the heck was that?!" Ruby shouted.


The man known as Master Chief was now well on his way to the observation deck and was pleased that he has so far not met with any resistance. He was bolting down each corridor with frantic speed and soon found himself in a small room with a holo-graphic display set up in its center. When he entered the room he finally took a moment to take in the condition of the ship around him. "How long have I been out?" He asked Cortana.

"Four years, seven mouths, ten days." Cortana responded.

The Chief hummed to himself for a moment before speaking once again. "Somebody should have found us by now." He said right before a massive surge of energy ran through the ship causing the panels and monitors to flicker and hiss violently. "What was that!?" He inquired.

"Censor scan, high intensity! It doesn't match any known patterns!" Cortana responds in a panicked tone.

"How close are we to the observation deck!?" Chief inquired.

"It's directly above us!" Cortana responds.

Having his answer Chief rushed out of the room and over to a large set of pressurized steel doors and he forced his hands into the thin crack between the two doors and began to pry them open. For a moment the doors refused to budge but Chief just put more strength into and finally they began to slide apart. However the moment a crack appeared between the doors a vacuum effect was created witch sucked him through the doors and send him flying out into the next section of the ship which seemed to be a shaft of some kind and it was so heavily damaged that it could no longer sustain life. Realizing gravity was still pulling him downward into the unknown Chief grasped onto the wall of the shaft and began to climb up toward the observation deck.

As Chief neared the top of the shaft Cortana called out to him. "Just a little bit more Chief and we will be there… Chief look out!" As Chief reached the top an energy sword wielding Covenant Elite stud over him and prepared to take a swing at him. Chief prepared to counter attack but before their the Chief or the Elite could make a move the sound of vacuum muffled gunfire erupted from behind the Elite causing its shields to flare violently and it to reel back in pain. This Gave Chief the perfect chance to leap up and finish it off with one swift strike to the back of its head with the butt of his assault rifle. With that done he steadied his weapon on the new unfamiliar figure in front of him. A short women in jet black armor with strange ear like extensions on her helmet.

The girl also had her unusually shaped weapon trained on the Chief. It looked almost like the combination of a submachine-gun and a folding katana. It was also connected to a long black strap that was rapped around the girl's armor. "Who are you? You and him don't look like your friends so why are you on board this ship? Were you a member of the crew?" The girl asked while motioning towards the downed Elite.

"Funny I was about to ask you the same thing. I am Spartan 117 you can call me Master Chief. As for why I am here, this ship is UNSC property so it only makes since that UNSC personnel would be on board. With that said you don't look like UNSC or an ONI operative. Are you a rebel perhaps?" Chief responded.

"It's Blake. And you're really a Spartan?! I would really like to know what a Spartan is doing all the way out here. It doesn't really look like this ship has any tactical value anymore so I doubt your guarding it. And you would be partly right about me. I'm not part of the UNSC or ONI but I am not a rebel I assure you. I am just a scavenger trying to get by."

Chief carefully inspected the girl's armor and weapons once again. "How did a scavenger come by such high end equipment? Even with bottomless pockets a civilian getting their hands on armor like that would not be an easy task."

Before the girl could give Chief an answer the voice of Cortana rang out from his helmet. "Chief more hostiles detected!"

With that declaration the Blake thought for a moment before speaking word. "Truce?"

"Truce." Chief repeated as he redirected his weapon towards the observation deck. "Alright Cortana lets do this!"


*Bang* *Bang* *Bang*

"Is that gunfire!?" Ruby yelled as her and her group ran down one of the many corridors leading towards the observation deck.

"That's not just any gunfire, that's Blake's Gamble Shroud I would know it anywhere!" Yang responded.

"We got to hurry!" Ruby declared as the thrusters on her back fired and she began to rapidly accelerate down the corridor and around a corner out of her teammate's line of sight.

"Ruby, hey wait up!" Weiss screamed after her charging leader but she was already too far ahead to hear her. "Well this is just great! Why is it that no one ever listen to me?!" She roared.

"I think we have bigger problems on our hands Weiss!" Yang said as the armor around her hands shifted and formed as set of large yellow gauntlets. On queue a pair of heavily armored Covenant Hunters dropped down from above the two scavengers with one of them on each side of the corridor leaving them no where to go but through them. Then the Hunter's lifted their massive shields up in front of them and leveled their glowing green plasma cannons towards the girls.

"Don't worry Weiss I got your back!" Yang declared.

"I know Yang, trust me I know." Weiss responds as she draws her silver rapier from her side while spinning the barrel of the weapon causing it to glow with blue energy. Then Yang and Weiss pressed their backs together and readied for a fight.

The Hunters eagerly accepted their challenge with the one facing Yang releasing a plasma blast directly towards the two of them. "I got this!" Yang screamed as she slammed her fists together and charged toward the enemy.
