Daughter of Jupiter Chapter 1 – Daughter of Zeus becomes a Roman

Hello one and all, Iskander Mandoraekon here with a new story for the Percy Jackson universe. I got this idea one day after watching the Smite trailer with Bellona and thinking about how she looked so similar to the way I imagined Thalia Grace to look, then I began thinking, what would have happened to the world of the Olympians if say Jupiter's personality did a switch with Zeus during the baby making process for Thalia or if say Thalia really didn't want her brother to be left alone, so she demands that Zeus turn her blood into that of his Roman side's.

Now many of you might wonder why I have this as a crossover for the beloved show RWBY. Well since I don't really know much about pre-Praetor Jason Rome, I decided to take a few characters from RWBY in order to have a character class, besides the fact that I like both Bellona and Sun Wukong from Smite, so why not use Sun from RWBY as her pairing?

I also created this idea for a multiple story outlet where I would be placing chapters of different stories in here after seeing the authors Sakurademonalchemist and BonesBoy15 do something similar with their Drabbles stories and Olympian One-Offs. If one of the stories in here reach more than three chapters and I can see it continuing, then I will make it into an official story.

That's all for now, have fun reading!

I do not own the Percy Jackson series nor do I own any of the RWBY characters, even though I wish I did because Pyrrha would never have died and I would have had Yang killing that bastard Taurus with his own blade.

Thalia Grace, only mortal daughter of the Greek god Zeus and the once famous actress Beryl Grace, was having a very odd week.

First her mother had become all warm and loving towards her and her two year old brother Jason, something that hadn't happened since Thalia's father Zeus had left the woman once again due to her badgering of the god king for immortality or being able to see Olympus.

It all started with the bitch of a woman actually paying attention to Jason, going so far as to change his diaper and even buy the little staple eater a new toy. Then she was actually courteous to her daughter like they had shared their deepest darkest secrets to each other from day one like one of those lousy soap operas instead of the constant yelling she had always leveled at Thalia for when the girl would confiscate her alcohol.

Now after a week of happiness that still had the daughter of Zeus staring at her mother with veiled suspicion, they had decided to have a picnic in the famous Jack London State Park as a way to get away from all the stress of their lives as a family.

However that perfect week and so far perfect day was shot to hell before Thalia could even manage to unpack the sandwiches they had made and packed for the trip.

It all started spiraling downhill when the girl of thunder saw her mother returning from the walk she had just gone on with Jason in order to have some mother/son bonding as she had put it, however what made it all come to a grinding halt was when Thalia noticed that Beryl was missing a certain object from her arms.

A certain blond two year old named Jason Grace.

Oakland, California

There was a massive storm over the city of Oakland with the Grace residence situated directly beneath its epicenter. Inside the one story house, if one were to look through the window of the residence, they would see a young black haired girl with electric blue eyes and a blonde woman that reeked of alcohol yelling at each other.

"How dare you call the cops on me, you ungrateful brat!" one Beryl Grace raged at her daughter as she slammed the door to her room shut after she finally woke up from getting shit faced after being arrested due to her firstborn calling the cops on her for giving Jason up to that prude Juno like she had been instructed to.

Oh sure, it would never go well in trying to explain to her sparking daughter that they had to give her two year old baby brother up to a goddess well-known for hating the spawn of Zeus. But Beryl had never been one to fully think beyond what she herself wanted, and fact one after the God King left her once again was to get Hera off her case just because she got cozy with the goddess' husband.

"You call me ungrateful!?" Thalia snarled at the poor excuse for a mother that stood in front of her, the admittedly mature nine year old's fists sparking with lightning as she tried to contain her anger in order to not kill the woman that spawned her via electrocution. "I'm not the one that left my baby brother to die in the fucking wilderness!"

Now many parents would make their child wash their mouth out with a bar of soap after catching a not even ten year old saying such words, however Beryl Grace is not like most women and reacted as she always did given her spoiled, former celebrity upbringing dictated. She slapped the daughter of Zeus across the face; not for the curse word, but for the fact that she would even talk back to her when she believed her plan to get the queen of the gods off her back was as amazing as she had been back in the days when she still had her acting career.

What the woman got in return for her 'kindness' was a quickly reddening Thalia as the demigoddess' eyes flashed dangerously with lightning arcing off of her all over her body.

"I fucking hate you."

Before Beryl could get off another word, or possibly slap her daughter again, the former actress found herself slammed into the wall of their living room from a burst of lightning striking her in the chest. The woman lost consciousness due to the pain of coming into contact with a hard surface and being electrocuted as Thalia grabbed several objects from around the house and stormed out the door, the heavy rain created by her anger doing nothing to deter her.

Sky above Oakland

Hera stared down from her chariot at the sight of her husband's bastard daughter running away from her home with clear interest on her face. Originally she had come to see why there had been such a massive storm over the city her new champion had come from, thinking that perhaps her cheating husband had once again decided to slate his lust with the Grace woman after his newest son had been delivered to her and Lupa, and believed that such a storm would keep the eyes of the other gods off of him.

Like he had often done before…

However what she found when she had gotten to the home of the woman her husband had woo'd, instead of finding her airhead of a paranoid husband, the Queen of the Olympians found the interesting sight of the king's Greek aspect's daughter being the one to cause the storm, the storm that got steadily worse the longer she argued with her mother; ranging over most of the city now.

It was enough to make even Hera sigh in sadness, both at the fact that had the girl been roman, she would have gladly taken Thalia as her champion instead of her younger brother, the other fact being that she was greatly disappointed with the way that woman approached being a mother. Honestly, even though she usually hated her husband's bastard children and could often be a spiteful bitch from her husband's constant cheating, even she would never condone giving a child to a mother that would slap them just because the mother believed they should be grateful for every little thing that happened in their lives.

It was the thing that she did next that would have many of the gods and goddess' of the Greek and Roman pantheons wonder if she had lost her mind and cause Zeus to enact a punishment that wouldn't have happened until after her newest champion, Jason, had turned sixteen.

Week and a Half Later; Stockton, California

Thalia screamed as she climbed another fire escape to escape the hellhounds that had been chasing her for the better part of the day. The kitchen knife clutched to her chest that she had stolen from her mother was now broken in half with its lower half sticking out the backside of an angry, ugly mastiff that was currently trying to maul her from where it was beneath the fire escape.

The daughter of Zeus quickly ran through the window next to her and pressed herself flat against the wall after slamming the window shut, trying to stop her whimpers of fear from getting out. Thalia then proceeded to sob in relief as she heard the thundering footstep and barking of the hellhounds leave the area behind after waiting a few minutes.

"Hello Thalia Grace," A feminine voice said quietly behind her.

The nine year, nearly ten year old girl immediately took a deep breath of fear as she tensed.

Somebody was here and they knew her name…

It could only be a monster…

The girl almost immediately gave an impromptu battle cry and threw her broken knife at whoever it was that was behind her before racing for the window she had come in through, not even chancing to look back to see if her weapon had managed to hit the person… or monster. She grabbed her bag of the supplies she had stolen from her mother's house and a few convenient stores, and the girl scrambled away from the would-be attacker, instinctively grabbing a large iron pipe as a weapon when she landed in the alleyway with the air beneath her cushioning her fall. Despite the fact that she knew that normal weapons never worked on the monsters that had been attacking her besides annoying them, she deemed it an acceptable weapon because she didn't have anything else.

"Such an underhanded attack does not work on me child," the voice said again from behind the frightened girl, somehow getting from the room she had just left and getting behind the girl without Thalia noticing. "While it might hurt a mortal, it would simply irritate someone of my caliber."

"Leave me alone!" Thalia shouted as she swung the bar behind her, with electricity sparking off the metal.

"You're the one who ran away from me, child," the woman said in mild amusement as she simply caught the sparking bar. "I only wished to speak with you."

"That's what those creepy snake ladies with wings said!" Thalia said as she struggled to take her weapon back from the, now that she got a look at her 'attacker', beautiful woman wearing a toga much like the ones she had seen from those Greek Mythology books her 'mother' like to faun over when reading about 'her' Zeus.

The woman had long, licorice-black hair that was bound in a type of ponytail that ran directly down her back from the bottom of her skull and she had a face of regal and unapproachable beauty that put that type her 'mother' once held in her prime to complete shame, and large, soft brown eyes that made Thalia want to lower her guard. She was wearing a glowing white gown with a cloak of peacock feathers settled over her shoulders and a golden lotus-topped staff in the hand that wasn't holding the demigoddess' bar.

The woman stared at her with a frown on her face as she remembered watching the confrontation between her husband's bastard and the two gorgon sisters Euryale and Stheno. "I am sorry that you ran into those two; however I will have you know that I am nothing like those whores, nor am I a monster."

The goddess clenched her hand around the iron bar Thalia had attacked her with and the rusted metal disintegrated in her hand and she drew herself up to her full height while in the form she had chosen. "My name is Hera, Queen of the Gods and the wife of your father."

"Oh great," Thalia said dryly as she stared up at the goddess before her, amusing the queen at how much enthusiasm had been shown in that sentence. "I am so sorry that I'm your bastard of a husband's bastard daughter; however that is not grounds for attacking me when we've never met before!"

Hera's eyes tightened as she was reminded once again of her husband's latest infidelities out of the hundreds of times he has cheated on her, before the goddess schooled herself, reminding herself that she wasn't here for something like that. "Admittedly, while I am angry with Zeus for once again cheating on me with yet another mortal and having a child with somebody other than me again. That is not the reason I am here."

Thalia's electric blue eyes starred at the goddess with confusion and veiled suspicion that in even Hera's opinion was well-deserved due to the fact that she was well known for screwing over her husband's children… case in point being Herakles, though he brought that on himself. "Why would you be here unless you wanted to get rid of me?" The girl asked as she gave the goddess an accusatory glance. "I remember a lot of the stories about Greek Myth when I was curious at the library and you're rather well known for hating the children of my father."

"I have come with an offer that would enable you to be able to see your beloved brother again," the Queen of the Olympians said as she stared down at the girl before her, the shocked expression on the girl's face giving a sense of enjoyment to the goddess and she continued before Thalia could ask any questions. "While many gods would look down on this meeting and what I am about to tell you threatens an extremely fragile balance between two factions that have coexisted very badly in the past."

"What are you talking about?" the ten year old asked in confusion as her electric blue eyes looked at the goddess. "What does this have to do with Jason?"

"You know that you are the daughter of Zeus, do you not?"

Thalia's nod gave the answer the female deity was looking for, having already guessed that the daughter of Zeus would have been told of her heritage by her boastful mother.

"What you probably don't understand is that with the gods, specifically the Olympians that your father and I belong to, there is a condition that happened a few thousand years ago that caused most of us to develop a multiple personality disorder," Hera said as she made sure the girl was paying attention to what she was telling her, even if she didn't know what this had to do with her baby brother. "When the Roman Empire came to be, our personalities took a massive shift to accommodate to the rigid structure of their culture after they had conquered Greece and took us as their gods."

"However, when that happened, the gods except for a select few were given different names," Hera said as she waved her hand, creating an image of a woman that looked just like her only with colder eyes; she was dressed in a blue dress with a cloak made of goat skin, which hung over her shoulders. Her face was stern and stately, while her right hand was holding the same staff her current form held. "My name was changed to Juno, while my dear husband's name was changed to Jupiter Maximus. While you are a daughter of the personality of his Greek side, your brother Jason is the son of Jupiter, his Roman personality."

"So Jay-Jay is a Roman, huh?" Thalia mused as she looked at Hera. "What would this mean in allowing me to see him again, from what you said earlier, it isn't exactly happily looked upon for the differences between them and the Greeks?"

"Over the centuries since the fall of Rome and the return of our original personalities, the Roman side remained and both sides of each gods' personality looks down on the other, which has unfortunately cause an untold amount of friction between the children born from the two different sides," Hera explained, the woman knowing how much trouble she could get into for simply telling her stepdaughter this. "Each time the friction became too much and snapped, it resulted in large wars that caused massive death tolls for Romans, Greeks and Mortals alike. After the most recent one that you would know of as the American Civil War, the gods decided that it was best to keep them separate and remove any record of them encountering each other."

"So since I'm Greek, I can't see Jason?" Thalia asked with watering eyes as she looked up at her father's wife.

"Yes, if you choose to turn down my offer," Hera said as she looked down at the demigoddess, said girl gaining a confused look. "I have seen how much you love your brother and the power you wield would be put to good use in the legion, who knows, maybe you'll be able to make a difference as the Praetor in the years to come."

"As such, after seeing your potential and your devotion to family, I have decided to come to give you an offer, which once taken cannot be reversed." The God Queen said as she held her hand out to the girl, "take my hand and you will be able to see your brother again, however, it will not be as the daughter of Zeus, but as the daughter of Jupiter."

"How will that work?" Thalia asked as she tried to understand the offer being given to her. "I thought I had to be born from my father's Roman side."

"Yes, when you are being born," Hera said with slight annoyance at this taking so long and the girl's stalling. "However as the Queen of the Gods, I have the ability to change a demigod's blood to that of their godly parents' different personality, in speaking terms, I would be changing the blood you gained from Zeus into that of Jupiter's blood."

"And with this, I will be able to see Jay again?" Thalia asked once again, wishing to make sure before she took the offer of the Goddess before her.

"Yes," Hera said before she found her hand occupied by the soft hands of her husband's bastard and a smile adorned the queen's face. "One last thing…"

Thalia looked at her stepmother with curiosity on her face about what the woman would be adding before a massive stream of pain began running through her body, making her feel like someone was peeling the skin of her body back like she had often seen in those science labs at the school her mother had sent her to and lighting her blood on fire.

"This is going to hurt. A lot!"

The girl's world went dark.

Several Hours Later

Argus, prized and loyal creation of Hera, opened one of the eyes on the back of his neck to check on the nine year old girl that was fast asleep in the backseat of the car he was driving, who he had been tasked with safely escorting to the wolven goddess, Lupa, by his patron Hera. The once giant could still see wisps of steam rising off the girl's skin from what Hera had done to her.

The guardian of Camp Half-Blood didn't envy the girl in the slightest, seeing her stir a bit, he didn't know if he even wanted to find out how it felt to have someone change a person's blood to something else, though he was guessing it would be extremely painful from what he had seen of the flinching the girl's unconscious form had been doing when his queen had called him. His eye on his neck closed and he returned his attention to the road and his steely blue gaze locked onto the billboard to the right advertising the entrance to Jack London's park, a place the girl had only been recently.

Argus soon pulled into a parking spot of the designated parking area that would lead to the meeting place that he was to meet Lupa with the former child of Zeus.

He then got out of the car and shook his charge awake upon opening her door and when he got a startled look from the girl that had only remembered pain the last time she was awake, the guardian motioned for her to follow him as he stepped onto the path that would lead to their destination.

"… Who are you and where are we?" Thalia asked as she stared suspiciously at the back of the hundred eyed man, wondering why she had woken up in the backseat of his car instead of by Jason like Hera had said she would be. She was simply tapped on the head by the creature that stood before her in order to show that it would not harm her.

Thalia then proceeded to walk into the forest behind Hera's creation, her nerves and survival instincts going wild and her electric blue eyes darting around to make sure they weren't ambushed.

The raven haired girl really hoped that she was just imagining the moving shadows…

When they finally came across a burned down lodge where Argus motioned for her to wait, they stood in a quiet silence for a moment before from the shadows of the lodge came a massive wolf that made the newly made daughter of Jupiter feel absolutely tiny, the girl only coming up to slightly above the wolf's knees. It had an extremely beautiful roanish red coat of fur and Thalia found her eyes immediately locked in an impromptu staring contest with two canine, silver eyes that stared into her own without blinking once.

"Tell me…" the wolf said as she turned her gaze from the girl before her to the hundred eyed man. "What is a Greek doing bringing me a demigod?"

Argus said nothing and instead pulled out a notepad that he then wrote on before showing it to the goddess, making Thalia believe that he couldn't speak and leading her to wonder if he had an eyeball on his tongue too.

"Is that so?" The wolf asked as she looked down at the pad in the man's hand before she cocked a wolf-brow at the being in question. "That meddler bitch likes to interfere in places which she doesn't belong too much, fine. Leave us Greek; I must judge the child you've brought to my home."

"Wait where are you going!?" Thalia demanded as Argus nodded respectfully to the she-wolf and walked away from the wolf and girl back down the path to where he had parked the Camp Half-Blood van.

Thalia looked over at the talking wolf as her demand was met with silence from the man; she glanced back at the retreating back of Argus, before walking openly up to the wolf that she had long guessed to be a goddess. The female wolf's piercing gaze had her stopping in her tracks as soon as she came within five feet of it and the wolf sniffed at her loudly before giving a soft groan.

"What is it with that damn Jupiter and being unable to keep his cock out of a bitch's womb?" The wolf asked with an exasperated roll of her silver eyes before she looked back down at the girl before her, impressed that she was standing her ground firmly and staring her in the eyes despite the slight trembling she had.

"Do you know who I am, daughter of Jupiter?" the wolf asked as she stared down at the girl. Thalia just shook her head, having only discovered the Roman side of the gods the day before.

"My name is Lupa," the now named Lupa said with a low growl as she stared down at the girl, only slightly wondering why she didn't have blonde hair like the two year old she had received from the alcohol covered woman two weeks ago and like many of Jupiter's spawn. "And from this day until I decide you are ready to fully join the legion, you will be training alongside a few other pups that I have received. Do you understand?"

"Y-yes ma'am," Thalia said with a nod and with that, the wolven trainer of Roman heroes turned around and walked into the forest with her new charge; leaving the burned out remains of Jack London's cottage behind to be filled with silence like it had been before they had entered it.

Hello, how did you all like this story chapter idea? For this story, I was hit with a burst of inspiration upon seeing Bellona from that new game called SMITE in one of their cinematics that is under the name of GMV/Centuries – Fall Out Boy (SMITE) if any of you are interested. I was struck by how similar Bellona looked compared to how I always envisioned Thalia to look like, only wearing Roman armor and wielding a large sword instead of her spear and bow. Then I wondered, what would it be like if Thalia Grace was the Daughter of Zeus' Roman side, instead of the Greek? What would happen if, instead of going to Camp Half-Blood where she would run into Annabeth and Luke on the way and be ripped apart by the hordes of hell before becoming a tree; Thalia instead went to Camp Jupiter, where she would be with her brother Jason?

In a sense, the most I am curious about is what changes would the world of Percy Jackson face if Thalia wasn't a main focus of the Greek side of things.

As I said in the top I created this idea for a multiple story outlet where I would be placing chapters of different stories in here after seeing the authors Sakurademonalchemist and BonesBoy15 do something similar with their Drabbles stories and Olympian One-Offs. If this or another of the stories in this little niche reach more than three chapters and I can see it continuing, then I will make them into an official story.

As of right now however, I do not know if I will continue this particular story or not and I will be putting my 'Rider of Tohsaka' story, which is already on my page, in here as the next chapter since it hasn't been updated in a long time, so don't be disappointed if it comes up next.

That's all for now, I hope you guys enjoyed the chapter.

Until next time, Iskander Mandoraekon signing off. Ja Ne.
