AN: This fic is the first in a two fic series that involves Harry Potter/ Halo and RWBY. Also, the time line has been moved up by 20 years. Harry is born in 2000 instead of 1980

Everything else has moved up in a similar fashion. Also, this is the rewrite of Magickal Soldier and is a response to the challenges of Symbiote Harry and Harry Insert by Whitetigerwolf

Requirements: Symbiote Harry

- Harry must, through whatever means you as the writer can imagine, somehow end up as a symbiote, similar to Marvel Comics Klyntar

- Harry must bond to another character (or multiple characters before settling on one they like/accepts them, similar to how the Venom Symbiote was rejected by Peter before being accepted by Eddie Brock)

- Harry must genuinely like, perhaps even be romantically interested in, his final partner

Recommended:

- Crossover with DC or Marvel (Declined)

- FemHarry (Declined)

- Harry bonding to a female character (Declined)

- Harry Bonding with Bellatrix Lestrange, Narcissa Malfoy, Fleur Delacour, or Luna Lovegood (whether these are the final bonding's or brief ones is up to you) (Nope)

- Harry being bonded to multiple female characters simultaneously and having the characters in question become romantically interested in each other (Maybe)

- If going with a DC or Marvel crossover, Harry becoming a symbiote because he is a metahuman (DC) or mutant (Marvel) whose powers permanently changed his physiology into that of a symbiote (Nope)

- Be creative and try to customize the look of the symbiote costume and the way Harry's host uses the symbiote's abilities; using the theme and costumes of the host is recommended (Oh you guys aren't going to believe the customization)

- Harry not being vulnerable to sonics and fire in particular due to him being similar to but exactly the same as the Klyntar symbiotes (Somewhat accepted)

- Harry becomes a symbiote due to a botched polyjuice potion where a portion of a symbiote manages to somehow get into. (Nope)

NOTE: Rather than just copying Venom or Carnage's look. Perhaps look at Carnage Queen, or Venomized Character covers, or Symbiote Fanart for different ideas on how a character looks. (The suit was taken from my fucked up mind)

Requirements: Harry Insert

- After dying, Harry Potter must be reborn into a new world, also known as another fandom

- Harry must be familiar with the world he is reborn into thanks to having read, seen, played, etc. the world he is now in

- Harry must use that knowledge to his advantage

- Harry must still be able to cast magic

- Harry CANNOT be in a M/M Relationship

- This one is more of a reminder than a requirement. As I have seen in many Self-Insert stories, Harry can be dumped into the world at the age he dies, as a newborn, or in the body of an establish character of that fandom, it's up to you.

Recommended:

- Harry reborn as a woman, or placed in the body of a female character and having to adapt (Declined)

Disclaimer: I do not own Harry Potter nor any of the aforementioned stories.

Chapter one: Rest Thy Soul And Begin Anew

Harry stared at the ceiling, looking at it with a gaze as empty as if he were blind. Time didn't exist for him currently, as he had hadn't really paid attention to its passing. It had been a day, two or maybe even five since he had returned for the summer.

Nothing seemed right anymore. His chance at getting a family was taken away from him and to top it all off, he had discovered that the reason there was such a large target on him was because of some prophecy that the old bat Trelawny had said.

So, after having returned to the place that he despised, he found himself only ever getting up to eat the small care packages that his friends sent him, or to write small and direct letters to his friends to leave him alone.

Honestly, he had no idea how long this would continue, but it seemed that today, the world had enough of his mopping.

Three loud knocks came to his door, and Harry rolled over, answering half-heartedly, "Yes?"

The door opened, as Harry could not lock it from the inside, and standing there much to Harry's annoyance, was Dudley.

"What do you want," Harry mumbled, not in the mood for his cousin's bullshit.

"You do not look good," Dudley commented, leaning his shoulder against the door frame.

"What's it to you?" Harry retorted.

Dudley shrugged, not gracing Harry with a response. Instead, he merely stood there patiently and silently, much to Harry's growing ire. "What do you want?" Harry repeated, trying to figure out what his cousin could possibly want.

"For you to get up," was the simple answer.

"Shove it," Harry immediately responded.

"Get up," Dudley repeated, not budging from his spot.

Harry rolled over, turning his back to Dudley.

Silence fell between them, and Harry wondered if the big oaf had given up yet.

"I'm not leaving," Dudley added, his tone surprisingly polite albeit stern.

"Well then enjoy wasting your day away," Harry spat.

More silence. Harry was starting to get confused as well as angry. What the hell had gotten into his cousin's head? Surely, he wasn't this polite and patient, how could Harry have missed it throughout his life. No, this was something new. But what had triggered it?

Harry rolled over much to his body's chagrin and looked at Dudley's passive face. "What is it you want?" Harry asked softly, finally to curious to be mad at his cousin.

Dudley remained neutral but found that he would answer the question. "Simple. For you to get your sorry arse out of that bed,"

Harry sighed, and groaned as he pushed himself out of bed.

Finally, he stood, and turned to face Dudley. "There… Happy?"

"Not quite. Now then, come," Dudley beckoned, and began to back away, eyes remaining trained on Harry.

"What?"

"Just come, I can't exactly take you anywhere with you just standing there," Dudley stated matter of factly.

Harry frowned, and looked most likely utterly bewildered. "Where in the hell would you take me?"

"Will you come if I bloody well tell you?" Dudley finally snapped.

Harry grinned, happy that he had confirmed no alien had possessed his cousin. "No promises but I'll most likely be more willing," he answered honestly.

"Fine, I'm going to take you to an internet café,"

Harry was puzzled, somewhat out of touch with the muggle world. "Did you say an internet café?"

"Yes,"

"What is that, something like a regular café?"

Dudley sighed, "It will be much easier if I just showed you. So, are you coming?"

Harry shrugged, but decided to nod and do so. Getting out of the room, Harry made his way towards the door, studying his cousin the entire time, half worried that this was a new type of prank to get him hurt.

While it was highly unlikely, Harry had recently learned that there was a lot that could happen even if it was improbable.

Walking out of the house, he found Dudley walking towards the local bus stop. This was curious, normally he would bitch to his parent's till they caved and brought him wherever he needed to go.

This seemed rather odd in comparison, as it showed Dudley as being more independent than Harry had previously believed. Taking this information in, Harry was also surprised when his cousin paid for his bus ticket. The two sat at opposite sides of the bus, facing each other. Harry wasn't really quick to forgive a life of abuse just now, and still was uncertain on how to act around this new version of his cousin.

The two remained silent, Harry not talking and Dudley not attempting to start a conversation, which Harry was grateful for, as it allowed him to focus on his thoughts rather than this new oddity before him.

An hour passed, and finally the duo arrived at the Internet Café Dudley had wanted to show Harry. The two walked in, and Harry found it to be more of like a mix of a regular Café that had been touched by technology.

Multiple terminals were provided, though they required a certain amount of money for their use, while the rest provided free Internet.

Harry was in awe at it all, the advancement, the fact that it was all available to the public, and how casual everyone used it made him rethink his initial distaste at coming.

Dudley first went to the person working the cash, and then after politely acquiring permission to use two of their computers, he led Harry off towards them. Sitting down next to him, Dudley began what Harry would find out to be three weeks of what was most likely the best things in his life.

Dudley introduced him to the internet and all its glory, showing Harry multiple shows on multiple different websites, these ranging from live action series to cartoons to Japanese animations called Anime. One of his favorites, which was an American anime, was called RWBY. He quite enjoyed how the characters used a mix of technology and soul magic to defeat evil.

And call aura what you will, it is soul magic, no matter how much Harry and Dudley might have argued over this, as Dudley tried to explain that the two were different.

Harry refused to believe this, and it led to a small fun rivalry that made them take different sides on the show.

This little rivalry bled into the game that the two played together at the Dursleys. Halo Reach, as well as Halo 4 were the two games most often played by the two, as they quite enjoyed the futuristic aspect as well as the simple things such as blowing each other up or killing the other with awesome assassinations.

Dudley's mission to bring his cousin out of his shell and into the modern world was working rather well, and over the course of two weeks, Harry was successfully integrated into the entire system, getting rather addicted to it all.

This all led to the current location of one Harry Potter.

Sitting peacefully in an internet café, and watching the last episode of RWBY volume 5, he leaned back, face in a scowl. 'Now I have to bloody wait,' he thought to himself, truly annoyed.

Fortunately, his annoyance would be forgotten. Unfortunately, it would not be due to any form of pleasant image or show.

As he leaned back into his chair, Harry found a small tick appear in the back of his mind. He realized, with a start, that it was wards being set up.

Rushing to the café windows, he looked out to see the street deserted, something which would have normally been impossible at this time of day.

Harry walked back over to Dudley and gave him a serious look. "Dudley, we need to get out of here, now," he stated.

Dudley, to Harry's ever lasting gratitude, nodded. Normally, there would have been an argument, but seeing the look on his cousin's face, Dudley decided that the only reason this was happening was because something dangerous was going on.

The two were about to exit through the back door, but quickly found it to be not a wise move, as two death eaters were waiting for them. Dudley, in a moment of strength, summoned his boxing skills to knock out the man in front of him, punching him directly in the face.

The death eater recoiled, while the other looked stunned. Harry decided to use this moment to finish them off, sending two transfigured metal spikes into their chests. The two coughed and spluttered, no aid to save them from their bloody end.

Dudley turned to Harry, shocked. "What the-,"

Harry interrupted his cousin with a shushing sound. "You idiot, you'll give away our position!" Harry hissed out.

Dudley nodded, though he seemed far from ready to concede the point.

The two however, were interrupted from their little convo by an explosion at the front of the shop. It shocked the resident mundane, and the others in the café, causing the few citizens left in this area of town to finally look up. The clerk at the counter looked shocked, as did many of the other few people inside the café.

Harry grimaced, and immediately ducked when he saw the spells that began to rain in.

Dudley was quick to follow his cousin's example and was rewarded by narrowly avoiding a spell aimed for his head.

Chaos ensued, with many of the denizens running out of the café screaming in fear, only to be quickly cut down by the forces waiting outside.

Harry and Dudley remained on the ground behind a toppled table, hoping to avoid many more attacks.

The Death Eaters outside, eager to do as much damage as possible, began sending bombardas only.

Dudley whimpered, though was quickly silenced by Harry with only a glare.

"What are we gonna do!" Dudley whispered furiously.

"The hell if I know!" Harry retorted back.

"Well think of something! You're the wizard 'ere! Magick something up already!"

"Like what?" Harry demanded.

Dudley paused, and then, slowly, a malicious grin spread across his face. "Halo,"

Harry blinked. "What do you mean Halo?"

"The guns! The weapons! Come on you stupid fool! Don't tell me that they haven't taught you to use your head in that school of yours!"

Harry paused, wondering if it was at all possible. Well, there was no way he was going to try.

"Fine, what weapons?"

"Assault rifles and grenades," Dudley replied.

"Alright,"

Harry concentrated, and focused his will towards piles of rubble that surrounded them. Had he been in school right now, many would have explained that what he was doing was not possible. However, seeing as he wasn't, he didn't have that limitation.

Quickly, multiple grenades and two assault rifles as well as three ammo refills were created, though Harry looked almost sick due to the amount of energy expanded in creating just the items.

Dudley nodded. "Alright, I've never used one before, but I pretty sure the concept is simple enough,"

"Just watch out for the recoil," Dudley added.

Harry nodded. Loading up their rifles, the two tried to ignore the constant screams and explosions that were occurring around them. They were even fortunate enough to not have a piece of the building collapse on them, but rather in front, serving as additional cover.

Harry looked over to Dudley, and was about to say something, when a voice he wished he didn't recognize began talking.

"Harry, I know you're in there," called the cocky voice of Lord Voldemort. "It has been a few weeks since we last saw each other, so I thought I'd pay you a visit,"

Harry sighed, muttering, "Dudley, Grenades first, got it?"

Then, much louder, he pretended to cough albeit quite realistically. -Cough- "Tom? How have-," Cough, "You been? I'm afraid your little party trick caught me at a bad time," Harry called out.

"Yes, well, it was meant to be a birthday surprise!" Voldemort joked maliciously. "Happy birthday by the way," he added as an after thought.

"Why, thank you! You're the first to say to me today," Harry quipped.

"Come outside Harry, the weather is certainly beautiful, it be a shame to waste it inside of a poorly maintained building,"

"Quite right, quite right," Harry continued, trying to buy time as Dudley messed around with the three grenades he had received, trying to figure out how they worked.

"Unfortunately, I haven't been in the best of moods lately, so I might come across as… unhappy,"

Another voice decided to pitch in their two pence. "Oh, is poor ickle Potter sad about his dear dead dogfather?" Questioned the insane Bellatrix.

Harry's expression immediately became feral, though none could see it. At the same time, Dudley gave Harry a thumbs up, signaling that he had figured out how to use the explosives.

Harry grinned. "Bellatrix! How good to hear from you! In fact, I'd been meaning to pay you back but just haven't found the means to get into contact,"

Bellatrix laughed, "Oh, and what might you think you could give me? Another weak unforgiveable?" she taunted.

The response she got though, was not words at first, but rather two metal balls landing at her feet.

"What's this? Pieces of stone?" she asked.

"No, it's your gift," Harry called out.

And then, just as Harry had finished speaking, the grenades went off, and Bellatrix and a few surrounding Death eaters were blasted off their feet as well as taken out by the shrapnel that flew off at high speeds.

None had time to react before a dent in their number was made, leaving Voldemort momentarily stunned. Harry smirked, and that was when their opportunity to strike occurred.

Jumping from the rubble, he and Dudley first threw the last of their grenades outside, and then began firing with the large assault rifles.

The Death Eaters were broken from their daze upon seeing more of the blasted little metal spheres, but had no time to properly act as they were also trying to dodge the metal rain of bullets flying towards them.

Many more fell, unused to the muggle fighting style and thus unable to properly counteract it. Voldemort quickly snapped out of it all and let his fury guide his actions.

Soon, under the guidance of Voldemort, the Death Eaters began to fight back. This didn't do much, but it did hinder the advance that Dudley and Harry had begun. The two were standing rather close together, ducking and dodging multiple different spells while continuing their fight against the masked bastards.

Voldemort ordered that they concentrate only with AKs and not use anything else, which Harry heard

"Dudley, get to cover quick!" Harry shouted, spraying wildly with his rifle.

The Death Eaters paused to duck, which allowed Harry and Dudley to retreat, but it was soon stopped by Voldemort who used golems to attack them. Dudley jumped behind the cover they had before, and quickly began reloading.

Harry meanwhile, dropped his weapon and pulled out his wand, shooting off multiple spells as fast as possible. They weren't powerful by any right, but they did manage to do some damage.

However, just as is expected of a dark lord of more experience, Voldemort countered all Harry's attacks and sent a purple curse that hit Harry right in the right side of his chest.

Harry gasped, coughing a little, but fought threw the momentary pain and continued to fight. Voldemort quickly banished Harry into a wall and sent a bone shattering cures at his legs.

Crashing into the wall, Harry only had a moment before one his legs went numb with pain as all the bones within were blasted apart. Harry screamed in agony and tried to get through the black spots in his vision.

Voldemort paused, and then smiled.

"You're finished Potter," he gloated, joy filling his body.

Now, as all evil lords before and to come, Voldemort decided to do his little victory monologue.

Harry looked up, and watched as Voldemort prepared himself for his long drawn out speech that was most likely going to be just as bad as anything the fool as stated before.

Thankfully, Harry was saved from the torment of it all by the arrival of the order. Voldemort quickly began to re-engage in the fighting, choosing to go directly for Dumbledore who had showed up. Harry, using the distraction provided created a plasma grenade, using his emotions to fuel his magic.

He felt the pain in his chest begin to worsen around the spot Voldemort had hit him, but he couldn't focus on that now. Trying to stand, he cried out immediately after placing just a small amount of pressure on his broken leg. Any further thought was interrupted by the scream of, "HARRY!"

Turning around, Harry saw to his surprise Hermione rushing towards him along with Ron.

His eyes widened, and he felt immediately sick at the thought of them being in danger with him. Ron quickly grabbed him by the shoulder, and shook him slightly, as Harry was rather dazed from all the pain.

"Hermione… Ron…," he murmured.

"Harry, we're here, don't worry," Hermione pleaded with him, tears in her eyes due to the state of him.

"Get me to Voldemort," Harry asked.

Ron looked like he thought Harry had grown a second head. "Are you bloody insane!"

Harry shook his head, "Not much time, quickly!"

Hermione wanted to protest, but Harry glared at her in the most horrific way that she fell silent.

Using a levitation spell, she assisted Harry to his feet, allowing the broken leg to float and not touch the ground.

Harry frowned, and quickly turned his wand on his friends, shocking them. Quickly restraining them, he left them shocked as he hobbled towards the ongoing fight between Dumbledore and Voldemort.

Upon arriving close enough, Voldemort turned towards Harry with a grin on his face. "Potter, still able to fight I see," he commented as he dodged one of Dumbledore's spells.

"Damn straight," Harry muttered.

Pulling his good arm back, Harry aimed for Voldemort as best he could.

"What's this? Are you going to resort to muggle methods to defeat me? Stone for your thoughts perhaps?" Voldemort quipped, sneering all the while as he created a barrier of earth around himself and Harry.

Ignoring it all, Harry threw the plasma grenade at Voldemort and watched as it soared through the air.

Voldemort was struck by the grenade hitting his chest, and he smirked, "Is that it?" he asked.

Harry coughed up blood, but smiled nonetheless. "Never is with me Tom. Rot in hell you bastard,"

Voldemort seemed confused, but then looked down to see the grenade had not fallen off and was in fact stuck to him.

His eyes widened as he tried to get it off, but time was not on his side, and the grenade exploded in a flash of light, letting off massive amounts of heat as it did so as well as a small shock wave that knocked Harry to the ground.

The was when Dumbledore burst through, and stopped immediately as he found the charred remains of Voldemort lying in a heap not to far away from the mildly burnt Harry.

"Harry," Dumbledore muttered, in shock, something which Harry was causing multiple people to be in right now.

"Hi-, COUGH, professor," Harry managed, blood leaking from his mouth.

"Harry, what have you done to yourself," Dumbledore murmured, confused by the actions he had seen before him.

"Nothing much… gasp… merely took out the bastard," Harry replied, though he was beginning to get pale.

Hermione and Ron both arrived by this time, looking a mixture of frantic and pissed. "Harry!" they both cried at the same time.

Harry tried to smile but found it rather difficult. "Hello…" he replied, voice starting to get weak.

"Don't you hello me!" Hermione yelled in his face, upset at the sight before her.

Ron on the other hand, took a different approach. Kneeling down next to Harry, he reached out to his best friend's arm face, as part of it was burnt.

"How did you do this?" Ron questioned.

Harry coughed, but then smiled, "Dudley… game me some… inspiration, shall we say," he then wheezed out more blood, worrying his two friends greatly.

Harry was become paler by the minute. "Professor! We need to save him," Hermione began as she turned to face Dumbledore, missing the tired look come across Harry's face.

Ron, rather surprisingly, did notice it, and came to a sad conclusion.

"You don't want to be saved," he murmured.

Hermione froze, and turned to look at Ron as if he were crazy, and then at Harry as if to confirm this. Sadly, the answer on Harry's face was not what she had been looking for.

"N-no, I don't… want… that," Harry agreed, his voice now very weak.

"B-but, you can't die!" Hermione shrieked, not able to comprehend what her friend was saying.

Dumbledore stepped forward, and knelt down to be at Harry's eye level. "Harry my boy, what are you doing?"

"Concluding things,

"Surely you jest-!"

"Sir!" Harry stated firmly, grabbing onto Dumbledore's wand arm, "Sir. I… am done. I am ready to move on," he stated. Then, with a determined stare. "Don't stop me. Don't… try… to stop… me,"

Harry began to see spots of black and was quickly losing all sensation.

"At last… I'll be… free… from…," but the rest of the words died on his softly smiling lips, and Harry Potter closed his eyes for the last time.

Afterlife

Harry opened his eyes to find himself amidst a crossroads, something which he found he didn't expect for the afterlife.

"Where am I?" he questioned, confused by the scenario before him,"

"Limbo,"

Harry jumped, surprised by the voice. Suddenly, a large spectral figure formed before him. The being, looking strangely feminine with its shadowy figure, formed into something much more human.

"Who are you?"

"The End and Yet, the Beginning,"

Harry frowned, puzzled, but then came to the only conclusion, "You're Death," it was a statement.

The being nodded, "That is what most would know me as,"

Harry shifted uneasily on his feet. "Where… where are my parents?"

"They have moved on,"

"Move on?!"

"Exactly,"

"But why?!"

"Because it was there choice. They rested for quite a while you know, not leaving until they were certain that you had at least gotten to meet them,"

"I…. I… but," Harry was confused, this was not how he saw his death as.

"It's alright child, this is simply how things go,"

Harry's shoulders slumped, and he sat down onto a chair that materialized behind him. "But then what will I do now?"

"That, is the question isn't it?" Death mused. "Fortunately, I have an answer,"

Harry perked up, though he looked rather mopey.

"You can reincarnate into any universe, or you may move on to the true afterlife,"

"True after life?"

"Heaven as you humans call it, known as the origin," Death explained.

Harry was confused, though that soon led to his intrigued expression as he recalled what Death had said about being reincarnated into any universe.

"Wait, you said I could be incarnated into any universe,"

"Yes,"

"Even Halo?"

"Certainly, I have much influence there,"

"Then may I?"

"Not in your current state,"

Harry paused, "What?"

"Not in your current state, you'll have three options to choose from and I'll grant you rebirth,"

Harry thought about it, then nodded. "It's just like a video game right? I play life as a different race?"

Death chuckled, "Exactly, quieting is committing suicide and dying naturally is game over,"

Harry grinned, "So what are the options?"

Death waved his hand, and then created three images for Harry to see. Next to them, conveniently was there stats, the personality the creature/being would get, and their abilities.

The first image was that of a sanghelli, it had the peculiar personality of being more honorable and less loyal, making its life rather difficult as it didn't follow the Great Journey as eagerly as one would hope.

The next, was a Forerunner with the passion to create rather than destroy, and that held a rather large grudge against the humans and flood.

Last, was a strange mass of goo that was known simply as a Symbiote. It had the ability to hold a magick core as well as grant one to its host. It was capable of many feats, such as genetic memory, as well as becoming almost any material. It was extremely durable though weak against energy-based attacks and bio weapons.

"May I make a recommendation," Death asked

Harry nodded, showing his consent.

"Choose the Symbiote, it will lead you down many interesting adventures,"

Harry thought it over and decided that it couldn't hurt. Besides, dying kind of led him to not really think much of death any more.

"So, what happens now?"

"Now, you will be sent to begin your new life. You will lose all your memories except for the ones concerning magick, the fictional knowledge you have acquired and gain certain understandings of magickal theory and how to fully utilize magick,"

"Cool,"

"My thoughts exactly. Now then, Symbiotes generally are given a name corresponding to a concept, substance or action. Which shall you choose?"

Harry thought about it for only a moment before he decided. "Chaos, the embodiment of magick,"

Death might have offered a smile it had a face. "Perfect. It has been most entertaining watching you live, Harry Potter. Now, Farewell, and may we not meet again for many years,"

Harry smiled, and found himself slowly disappearing into little sparks. He closed his eyes and knew no more.

And Cut! Alright, here we are with the rewritten first Chapter of this fic. I will be updating this one hopefully soon, as I have devised a new schedule for writing.

But for now, please leave a review with your thoughts on it all. Thank you and see you soon! (Not really for the seeing part =P)

Ciao!
