Hello, welcome to my new story. For any readers of my Universe vs Butterfly Story, don't worry, that will be finished, though I'm going to have to do that in august, because Starting on July 4th, i'll be gone for three weeks at camp. With the release of my third full on fic, Reverse Diamond Falls, I felt the need to release this idea I had cooking up for months. Again, these are my two most favorite characters, and while I would love them as friends, what if they were more? What if they were brother and sister? Just a random idea I had.

Now this will be an au for both shows, mainly Steven Universe for reasons I will address later. Just know that the Gems, Rose included have been on Mewni, as well as other dimensions. Some episodes I will revamp and add Steven, but for the most part, I will try to be as original as possible. Also expect some slight, not terribly big, but noticeable changes in Stars personality here. In the show, its no secret she's irresponsible and flighty, but add a little brother she always tries to impress and protect, that will give her a motive to grow up a little more. I hope this fic is enjoyable.

I owe nothing.

Within the outer borders of Mewni, was a little blonde with bulging blue eyes and pigtail. She wore a cure, blue poofy dress along with a little golden crown on top of her head. This plucky little girl was happily and randomly hopping all around the place as she wandered off to who knows where. Today's obedience lesson happened to be one of the most boring ones she had been in, so she decided to make the most out of it by taking on of the carriages and ride them around the kingdom. Unfortunately, one of the guards as well as her father just so happened to spot her, and tried to get her down. They gave chase, which spooked the horses that Star was using, which made them run faster, much to the little girl's excitement. But now the horses were tired and not moving somewhere in the outskirts of the kingdom, and the little Princess of Mewni, Star Butterfly, just randomly hopped around, still feeling the effects of adrenalin from the little ride she had just went through. She wondered why her parents made her go through such boring things anyway? Why couldn't she just be outside all the time and enjoy the thrills of a carriage ride chase? Wasn't the point off being a princess having fun with all the power you were given?

Star had finally calmed down enough to sit down for a moment, not really caring if she was sitting on dirt and getting her dress all messy. To her at least, her clothes were a little too clean. She sat as he looked up in the sky. Too think, out there was only a small amount of what the universe held. Other worlds, other places, and so many people to meet, some fun, some dangerous, and some just plain awesome. Star was determined to see them all, to see everything. She was never going to be bound be just Mewni, she would have the funniest time of her life.

But at the moment, she was just a kid, a kid that couldn't really go places other than the outside of the castle, heck she was lucky enough that the horses happened to be scared enough to go this far. She sighed at her limited options, and how alone she was at the moment. It wasn't as if she was without friends that understood her, she had plenty of those, and the people of Mewni were friendly enough to be around with. It was just that her closest friends couldn't be around her all the time, and if she had to be honest, she didn't know whether or not people liked her for herself, or the fact that she was the future ruler over all of them. She really wished she had someone to play with all the time, someone who could know what it feels like in her situation. Someone who enjoyed fun and laughter and exciting cart chases. She had also been thinking about monster fighting, so that was important to. She could only wish though, for what were the chances that….

Rustle, rustle, a sound from the bushes came.

"Hello, is anyone there?" she asked, more curious than scared. "If you're going to kidnap me, at least allow me one more pony ride before I we go." She innocently stated as she gestured towards her horses, which had fallen asleep in their state of tiredness.

Rustle, rustle. The sound of the bushes became louder and more prominent. Star once again shows no fear as she tries to approach the hidden figure. She could only hope that whatever lied behind the little green plant was friendly and will to give her a ride back home.

"Come out please, I don't bite, well, at least not at everyone, much." She stated as she tried to ease the nerves of whatever it was, thinking it might be shy.

"Fine, I'm coming to you, just, please, please don't freak out and run, that's usual my mother's thing." She said one last time before approaching the bush. She pushed aside the twigs and leaves that made up the plant as she made her way to the other side. Nothing. Not a thing was there in front of her. She looked up, wondering if she missed anything, but she once again, saw nothing.

"Aw man, I was really hoping somebody would try to kidnap me, would've been fun to be chased around." She said, slightly disappointed as she turned around to make her way back to the horses, when…

"ba" A weird, young sounding voice filled the air, which stopped Star in her tracks. She looks around once again to see if something was coming close to her. She once again sees nothing, and before she could move on and assume it was the wind, the voice comes on again.

"Bah, ah, tah." The voice randomly says. She looks in every direction, wondering where the source was, hoping to find it, but she sees nothing. Suddenly, she feels something small, but noticeable on the front of her leg. It felt like putty was grabbing her led, moist and soft, but didn't really have a strong grasp. She slowly looks down to see what it was, hoping it wasn't dangerous.

What she finds, was not something she was expecting. On grabbing her leg, was a small baby. Maybe only a year old, maybe even a little less than that. He was chubby, like most baby's with clean, flawless and soft skin. He had a big puff of curly hair, bigger than what one would expect from a baby. He wore a reddish, almost pink onesie on. What was most interesting, was the big pink gem sticking out of his naval. The shirt had one an opening in it, as if to show it off. Its eyes were brown, but filled with curiosity and wonder as he approached the larger girl, not showing any signs of worry, discomfort, or fear. The little blonde princess could only awe in the sight of the little boy,

"Awwww, a baby! What are you doing all alone? Are you trying to escape your classed to." She innocently cooed as she kneeled down to his level. The baby just lets out a series of random vowels and consonants as he reaches out his chubby little hand, trying to grab hold of the little face. Said girl just smiles as she attempts to pick the baby up. "You just want to be with some one, don't you?" She holds him out in front of her, staring face to face. The baby just gives out a smile as he reaches out for he girl. "Aww, does the little cutie baby want a hug?" She cooed again as she proceeds to do exactly that. The warm and squishy body the baby was just so nice to hold on to, it gave the little princess a little feelin on the inside. She didn't know exactly what that feeling was, but it was a good feeling, and she didn't want it to stop. Likewise, the baby seemed to share the same sentiment. He didn't know what was going on or who this girl he was hugging was, but he felt warm and safe around her. Plus she was hugging him, someone willing to give out hugs surley couldn't be bad, right?

"So where are you from little guy?" She asked once she felt her arms getting tired. She sat down, with the baby right on her lap, leaning against her chest. "You aren't alone are you?" She questioned. The baby, being, well, a baby, couldn't answer as he just held on to the little girl. "If only you could talk, then maybe things would be better, I mean, not that's its bad that you can't talk, it just gives me more opportunity to say more, as well as a chance to finally speak what I think, you know what I mean?" She asks. The baby only makes a smile at her as he makes bubbles with his drooling saliva. "I'd knew you agree with me, you have that smart look on your face." She laughs as the baby stares at something to their left. Something that casues the small but bright smile to go away. Something was amiss, and somehow, the baby could sense ill intentions coming their way. "What's wrong?" Star inquires, as she sees the frown slowly form on the baby's face. "Was it something I...", her squeaky voices just trails off as she finally notices what the little by was staring at. It was a big, fearsome looking creature. It was as big as a rhino, with long poofy white, messy hair. It had no eyes or ears, only a mouth with rows of sharp teeth sticking. Spikes also stuck across its bluish, green body as it approached them. What was strange about it however, was the fact that it had some sort of crystal sticking out of its body right on its right front leg, not too dissimilar from the gem that the baby had on its stomach.

Both younglings were completely silent. Neither didn't want to set off the monster off. One false move and they could get eaten or worse. Star, with the baby still in her lap, began to scoot slowly in the opposite direction, making sure to not make too much noise. The monster didn't seem to notice as Star begin to sigh inwardly. Now all they had to do was...

"achoo." The baby sneezes, prompteing the young girl to cover his mouth. "Sssh" she said, before notice something slimy and warm covering her hand. "Eww, baby spit!" she creamed, before promptly covering her mouth, not caring that it was still covered in the baby's drool.

Sure enough, that was enough to set off the monster. "Raaaaagh" it howled before charging. "Come one, baby, lets get moving!" She screamed as she picked up the little boy and ran as face as her little legs could carry her. She was panicking. She had always dreamed about fighting monsters, but she never expected to fight one so soon, and especially not one so nasty and violent. She ran right through the bushes, tearing up her dress a little as she did, having no time to make a safer path. She made her way to the carriage, holding on to the reigns as she made sure to strap in the baby, who smiled, not really noticing that they were in danger at the moment.

"Glad your able to enjoy yourself, now lets get out of here!" She yelled as she used the reigns to snap the horse awake. And as such, they immediately took off to the castle. Star's heart rate slowly started to slow down as sounds of the monster began to grow a little faint. She could only look ahead as she saw the kingdom in sight. Dread filled her bones. She knew that she would be scolded at for skipping her class, running off, and putting herself and a random baby. She looked back on the baby, who had somehow managed to get his foot into his mouth, which softens Star's mood a little.

"At least one good thing came out of it." She smiled as she finally lets her guard down, thinking the worse is already behind her.

BASH

Star barely had time to react. The monster had somehow gotten in front of them, which prompted the horses to run in opposite directions. This snapped the reigns as the cart was about to head into the monster head on at full speed and force. Star, without even thinking, grabbed the baby and jumped off the cart. She held the baby in the air as she did, making sure she took the full brunt of the impact. The baby just ended up with a few dirt marks on the cheek and maybe a small cut on the left arm, but he showed no visible signs of pain. Star ended up getting a bruise on her cheek, leg, as well as a quite a few scars scatter across her body. She tried her best not to cry in pain, espeacilly when she saw that the baby was alright. Unfortunately, the monster was still coming at him, slowly, but surely it would come at them.

Star immediate got on her feet, stumbling a little as she got in front of the boy. "Stay back baby! He have to hide, she said as she was prepared to protect him. Star felt like one of her more heroic and brave grandmothers of the past as she was prepared to sacrifice herself. She could only hope that the statue that they make in her honor resembled her perfectly. The monster had finally reached her, finally ready to take his mark and slash the little girl. It raised up his paw, and took a powerful swing at her, while Star closed her eyes, fully prepared to accent her fate.

clang

clang

clonk

clink

Several sounds were made, but none of them were the sound of a smashed little girl. Star looked around to she what had just happened. She found herself surround by some sort of bubble of pink light. She didn't understand. She didn't have the family wand, and nobody was around her to do such a thing. What could possibly...

She looked down at the baby she was just about to sacrifice herself for. The gem that stood out of his body was shimmering, glowing a bright pink, the very shade of pink that the bubble was made out of. She picks him up. "Whoa, magic baby." she states as her eyes bulge in the sheer awesome act that was just preformed in front of her. "Can you do anything else to help us out of here?" She asks, seeing as how they may have an advantage over the monster now.

Steven simply giggled as his gem glowed even more, an d on the outside of the bubble, spikes shot out of it, turning the pink ball into a flail. The spikes cause the monster to flinch back a little.

"Ohhh, this is going to be sweet!" The little princess shrieked as she held the baby close to her self as she charged at the monster.

"Find her, find our daughter!" Order the Queen of Mewni, Moon Butterfly. She, along side her husband River had been searching for their daughter for hours, with no luck in finding her. She was known to run off at times, but she never was out for this long. It scared them, but it especially frighten the valiant Queen. The king could only comfort her as they ordered the guards to expand their search.

"My dear Queen, you must simply calm yourself, worrying about out daughter isn't going to help us any further." River said.

The queen just sighs, knowing the truth in his words. "I know River, but I can't do anything else. I have all this power" she holds up her blue staff, "and I'm completely powerless in helping my own daughter." She cries out in frustration.

"My dear, Star may be young, but she knows how to take care of herself, most of the time" he sheepishly adds that last part, " Our Daughter is a fighter, she is not one to be deterred so easily."

The Queen sighs once again. "I know that, River. It's not just this I'm worried about, its her whole future that's got me worried. If I'm right, then Star's has a lot of trials and trouble ahead of her. I need to be serious about this, I'm going to have to give my families heirloom to her someday, and if stuff like this keeps up, i'm afraid she'll be overwhelmed and unprepared by what comes next." He head falters as she expresses her worry.

"Moon, my dear, Star won't be like that. She'll have us by her side, she'll have you." River simply states, resulting in a smile from the queen.

"I suppose so, but even still.." The Queen doesn't even get to finish her sentence as she is interrupted by a incoming guard, "My King and Queen, the Princess has been spotted just on the out skirts of the castle, and reports say that she was fighting some, some creature." The guard reports as he bows.

Upon hearing this, the relieved and shocked parents waste no time as they make their way to the catsle outskirts. They were prepared to destroy anything that dared to harm their daughter.

Once they made it, they couldn't really believe what they saw. Their were various dents and cracks on the flow, and even a crater, which in the middle of, was a blue gemstone. Next to the crater was their daughter, attempting to play patty cake with a baby boy. "Come one, you can do this." She encouraged as the baby just calmly clapped the girls hand. This was enough for the girl as she shouted "Hooray!" and hugged him.

"Star, both worried royals shouted as they hugged their daughter. "Star, don't you ever run off like that ever again!" Moon sternly but lovingly said. Tears filled her eyes as she was finally comforted by the hugging of her daughter.

"Star, what happened, nothing hurt you, right?" River cautiously asks, hoping that she didn't really encounter something that would've hurt her.

"Oh I did, but this Magic Baby saved me!" She said as she picked up said baby, who at this point fallen asleep. Her parents eyes widen at her statement. "I found him alone when a monster cat or something came, and I ran, and he crushed the carriage and was about to crush me, but than this magic baby made a magic spike ball and I used that to fight the monster, ohifeelsoawesome!" She shouted as she barely breathes in from all that talking. The parents eyes got even wider as they stare at each other, having no clue as to what to make of that sentence, or how to respond.

"I love this baby!" The elated Star shouts. "Can I keep him?

Writing 3,000 word's is getting easier now, though that's mostly because this chapter was so much fun to write about. Never underestimate the cuteness of the star Children.
