Hello and welcome readers to my Steven Universe fanfiction: "Gem of War"

I'm a fan of Steven Universe, but it took me a while to get into the series. What can I say, I didn't find this show to be all too interesting when I first heard about it. I just thought that it was going to be another bland cartoon from Cartoon Network with an annoying main character with some stupid name. But after seeing all the fanfics and how many people were actually watching the show, I decided to watch it again and then saw how much of a great show it really was. But then again, who wasn't like that. It's not perfect like some people think it is and I do have issues with the show, but I really do enjoy it.

I've looked over many of the other fanfics that the fans of the show made, and some are good, but I haven't seen anything that really wanted me to keep reading it. And so, it inspired me to think up a story and this was something I've been wanting to do for a long time. When I looked at many of the other stories, I saw every few where the OC is a human-gem hybrid. So, I decided to take a chance.

But enough talk, and before we get into the story this is an OC x Pearl story.

Many of you voted for the katana as the Gem weapon of choice for the OC, and so it will be his weapon.

I own nothing, except for the OC. Steven Universe is created and owned by Rebecca Sugar and Cartoon Network.

It was nighttime, and the moon and stars were out.

About ten minutes ago, Isaac Infinite had been running for his life.

At the age of 18, he was a tall Caucasian with a thin athletic build with medium length, messy blonde, and green eyes. He was wearing a red plaid shirt which he kept the sleeves rolled up to his elbows, gray jeans, and black and red shoes.

After running for his life, Isaac slowed down and was now walking down the street. After a week of traveling alone, both on foot and by transportation, he had finally made it to his destination; Beach City. It was a small town in Beach County in the state of Delmarva, USA. It was a town that's largely unknown to most of the country. It was mostly just a place that people of Delmarva would travel down to for the summer, due to its white sandy beaches and beautiful scenery.

But for Isaac, it was the place for answers. However, things didn't go according to plan.

Panting and almost out of breath, Isaac turned right on the final block. Exhausted beyond what he could've imaged, he finally stopped and leaned his back against the wall of the shop he had come up next to. It was a donut shop called the Big Donut.

Taking a moment to catch his breath, Isaac sighed in relief and closed his eyes. "Made it," he whispered.

But the calm wouldn't last him. About three seconds later, a dim light shined near Isaac. He opened his right eye and looked down. With the black sleeves already rolled down, his most distinct characteristic showed; a long tattoo of chains that spiraled down his right arm. It started in the middle of his upper arm, before coiling down to the very end of his arm, before it stopped spiraling at his wrist and continued onto the back of his hand.

And on the back his right hand was where the glowing was coming from: an Onyx gemstone that was in his hand.

"Shit." Seeing it glowing, Isaac quickly pushed away from the wall and started running away.

He ran onto beach that the town was known by. Isaac then turned left and started making his way around a large cliff located at the end of the city, near the ocean. It was the most noticeable landmark in Beach City, as it was the largest. Hoping that there would be a much more open area in front of the cliff, Isaac decided that he would fight the monster chasing him there.

Isaac looked down at his gemstone. The gem was glowing brighter now. It was getting closer. Isaac was starting to get more anxious. However, when he looked up and forward, the blonde saw that he had reached the front of the cliff and there was more than enough space to fight the monster.

"RAAAAGGHHH!"

Isaac quickly turned around when he heard the horrible roar and the monster charged at him.

He quickly put up his arm and the jaws of the monster bites him. Isaac grunted in pain, but turned his back and flung it off. The monster landed on its feet a few feet away, jumped up, and turned around to face him. This allowed Isaac to get a look at it, while his arm bleed. It was a bipedal and humanoid shape creature with two arms and legs, arched spines, and large round heads that prominently display its big nose, gaping jaws, and huge teeth. Its skin was black with glowing green stripes, it had no eyes, and displayed on its nose was a gemstone.

"Ugly motherfucker, aren't you," Isaac said, but wasn't prepared when it lunged at him. It jumped on him and pushed him down on his back. "AGH!" Isaac gritted his teeth in pain as the claws of the monster dug into his shoulders. With its prey pinned, the monster moved its head down and opened its jaws. Thinking quickly, Isaac was able to move his left arm and stopped the head by grabbing its gem.

Even with his also superhuman strength, Isaac was struggling to push it away. So, with his other shoulder still pinned, Isaac used his legs and kicked the monster off with both feet. It flew back a couple meters before bouncing a few times on the ground.

Isaac quickly got to his feet. The monster was also getting back up, shaking its head to clear its head of pain. He then looked at his right hand and held it up high over his head. A ball of white light appeared in his palm, and soon it turned into a weapon.

That weapon was a Japanese Katana sword with a black blade with a glowing white edge. The handle was black four lines going down grip, which starts off straight at the top, but soon spirals down until it reaches the bottom. The cross-guard was in the form of a black diamond. The pommel was a yellow star, but at the tip of the top point was a short chain of only four white links.

The Onyx continued glowing, and Isaac got into a fighting stance. The katana held out in front of him.

The monster roared and charged again. It attacked Isaac with a swipe of its claws, but Isaac parried it with his sword. It continued swinging its claws at him, wanting to rip him to shreds. Isaac blocked the next one, but jumped back to dodge the third swipe. Isaac saw it leap at him with its fists and arms raised over its head. He jumped out of the way before it smashed its fists into the soft sand.

However, Isaac wasn't quick enough when the monster backhanded him.

He screamed in pain, as he was sent flying into the air. Isaac then yelled in pain when his back hit not on soft sand, but against a large stone hand that was halfway buried in the sand. His eyes were closed in agony, but when he opened them, he saw the monster charging at him.

Know that if he didn't think fast he was going to die, Isaac rushed at the monster. Like a game of chicken, the two charged almost like they were intended to ram into each other.

The monster jumped at the human, claws extended out to kill him.

Isaac, however, got down and slide forward baseball-style. The beast over shot and started flying over him. Seeing the opening he's been looking for; the blonde thrusted the katana into its chest.

The monster shrieked pain, as Isaac's slide gave him the momentum to cut it down its body.

POOMPF!

Suddenly there was a loud popping sound as the monster's body was destroyed into a large cloud of smoke. There was no blood. No teared-up body parts. Just the gem. That's all it ever was.

The gem fell down onto the sand. Isaac stayed laying where he was on the beach, but let his arms fall down, stretched outwards. With the threat gone, the Onyx finally stopped glowing. The katana disappeared in a flash, going back into his gem. It was finally over.

Exhausted from being on the run and fighting the monster, all Isaac wanted to do was lay there on the beach and fall asleep. He almost did, but knew that if he didn't get the gem contained, then it would reform and hurt more people.

It's already killed a family in their home, he wasn't going to let it harm anyone else.

Still feeling the pain and his strained muscles and his left arm, Isaac groaned as he moved his body to sit on his knees. Struggling, he then stood up and walked over to the gem. His shirt was torn, and blood stained it at the shoulders. His right side had three claw gashes—when the monster back handed him, it slashed its claws on him too.

But they'll heal quickly. Just like most flesh wounds. However, it didn't stop from hurting.

And by the time Isaac reached the gem, all the wounds were completely healed in an instant. It was another ability that he had, along with his strength. But he wasn't invincible, and there were injuries that he wasn't going to be able to heal from.

He then got down on one knee and reached his right hand for it, but didn't attempt to grab it. Focusing while fighting off his exhaustion, the blonde man conjured a silver bubble that had the gem inside of it. Using both hands, he lifted it up with touching it, as it floated between his hands. Isaac sighed and tapped the top of the bubble with his right hand and it disappeared.

He didn't know where they went off too. But he knew that as long as they were in someplace safe, that he didn't have much to worry about.

With the threat gone, Isaac took the moment to close his eyes and just take in the night breeze of the sea. The wind blew on his face and into his blonde hair, and for the first time in a long time Isaac felt at peace and…even safe.

His ears heard the sound of feet running across the sand, along with some voices he never heard before.

Isaac never had the chance to see the people coming towards him, because fell over to his right and passed out.

His gem started glowing again.

"GEM OF WAR"

Chapter 1: Gem Glow

When Isaac came to, he wasn't on his on his back. And he wasn't outside. Laying on a comfortable bed, he groaned as he was beginning to open his eyes. However, he also felt as though something was clawing onto him.

As he cracked open his eyes, he was greeted with the sight of two gnarly mandibles with an eye located at the base of them looking right at him. It then roared at him.

"WOAH!" Isaac yelled as the mandibles lunged at him. With quick reflexes, Isaac quickly grabbed the jaws, the upper mandible with his right hand and the lower mandible with his left, and held the creature back from chumping on his face. Using his strength, he twisted the head upside down and it poof away. Isaac quickly summoned his katana and jumped out of bed. However, he stopped when he saw where he was and what was going on.

Isaac fold himself on the upper level inside of a modest-sized house with one large interior room. The upper level had the bed he was sleeping in, while the main interior contains a lounge with a fireplace and a kitchen/bar. However, deep in the far side of the house's interior opens into a stone and rocky area with an ancient-looking gateway and a circular platform in front of it.

However, as nice as it all was it was swarming with large, centipede-like Arthropods. Each of them had upper portions that were covered with a chitinous, bumpy, dark green exoskeleton throughout the body, with a single pair of legs of the same color. The lower side of each segment was a light green and slightly translucent with a yellow-green diamond shape in the middle of each of it.

"What the hell!" Isaac exclaimed in shock, before another one of the centipedes was sent flying right at him. He quickly dodged it and looked to see where it came for.

He was surprised to see near the kitchen was a tall and somewhat muscular woman with medium, maroon colored skin, and black hair styled into a cube-shaped afro. She wore a black and crimson bodysuit, with cubic shoulder pads—the right one being magenta, the left one being crimson—and a pink star with a magenta outline on her chest. She almost wore a pair of triangular futuristic, translucent orange-tinted shades.

Isaac watched in amazement as the strange woman battled the monsters using a pair of oversized gauntlets that covered half of her lower arm. Each one had a red and light red spiral design around the entire shaft, red and dark red fingers and fingertips, and contained the same star motif on the tops and bases of the gauntlets.

She punched the centipedes around her away. Then one of them landed on her head, but she grabbed it and pulled it apart in two. The woman then looked up at Isaac and saw that he was awake. "Good morning," she said in a calm and collective voice, and then started fighting the bugs again.

"Yeah, hi," Isaac said with an unsure wave. The sound of whipping then brought his attention to another strange girl.

This one was way shorter than the first one, with a somewhat stout build. Her skin was a bright lilac, and she had thick, messy pale lavender hair that went down to her ankles, with a large bang that obscured her left eye. She had plump lips, a small, upturned nose, and dark indigo eyes. She wore a mauve, oversized, off-shoulder tank top with a black bra underneath, along with black leggings with star-shaped cutouts on the knees, with a tear above the left star, and small pointed white boots.

Then weapon she was using was a multi-tailed dark violet whip, with a cross-guard in the form of a lavender star. There were multiple shards of purple gemstones embedded on the main lash, with a large gemstone as the pommel.

However, as she fought off the bugs, Isaac's attention was caught when he saw a gemstone that was located on her chest, and the bottom half of it is usually covered by her shirt.

"'Sup, dude," greeted the purple one. Isaac gave her a small salute before his attention was drawn to yet another strange woman.

This one had a slender, thin build with ivory skin, sky-blue eyes, a pointed nose and thin lips. She looked to be two inches shorter than Isaac. Her hair was a peach color and resembled a pixie-cut in the front, while in the back, her hair leads to a point. Just like the other one, she also had a gemstone, but it was located in the middle of her forehead.

Her clothing consisted of a sleeveless, sky blue top that had a translucent chest and transferred into a transparent silk ballet skirt around her waist. She also wore short salmon pink-colored leggings, light-green socks, and slip-on ballet flats to match.

This woman was elegantly fighting off the bugs like a ballerina with a spear that consisted of a glowing blade with a white grip and a cyan, gold, and white colored pommel shaped like a star. The head of the blade spiraled down the upper shaft, becoming less sharp on the lower shaft.

Though she was just as strange as the others, Isaac couldn't help but think she was very pretty.

"Oh, good. You're awake," said the skinny woman, stabbing a centipede. "That means we'll finally get some answers."

"You get answers?" Isaac exclaimed. "I don't even know where I am, or who any of you are!"

"Hey, guys! You won't believe this!" said a new, much younger voice. Isaac turned his head towards the door of the house and saw a young boy who was relatively short with a thick, stocky build, curly black hair, and full black irises. He wore a pink T-shirt with a gold star in the center of it. He also wore cuffed blue jeans and salmon-pink flip-flop sandals.

The boy looked at Isaac and after a second his eyes filled with excitement. "You awake!" Suddenly a centipede jumped onto him and tried to bite his face off.

This sprung Isaac into action and he jumped at the two. He landed near the boy and used his katana to hack the head of centipede clean off. After that, Isaac offered him his hand, as the boy shared at him with stars in his eyes. "You okay," the young man asked.

The boy took his hand and Isaac helped him up. "You've got a sword!? That's so cool," the boy said with amazement. "Can you do any cool tricks with your gem?"

"Maybe later, but we've got a bigger problem." Isaac turned and placed himself in front of the boy, getting into a fighting stance.

"Awesome!" The kid placed the mini refrigerator he was carrying on his back onto a seat, near the window. "What are these things," he asked, as Isaac stabbed one in the head.

"Me ask first." Isaac snapped, cut another centipede. "First, you got a name, kid?"

"My name is Steven Universe," Steven replied.

Isaac stabbed another one that jumped at him, but left it on his blade as he looked back at Steven with a strange look. "Your last name is Universe?"

"That's right." He then pointed at the maroon one. "That's Garnet." The purple one. "She's Amethyst." The pale one. "And Pearl. What's yours?"

"Uh…"

"Ugh! Steven, what have we said about talking to strangers," Pearl groaned, pulling out a bug from underneath the table and picking it up. "We'll get these Centipeetles out of your room and then we can talk with our guest. We think they were trying to get into the temple."

"Aw. You don't have to get rid of them," Steven said, as he and Isaac walked up to her. "They're really cool." Then, without warning, the Centipeetle that Pearl was holding spat out a green onto the floor near Isaac's feet. It turned out to be acid, as it melted away the floor board. Isaac yelped and leaped back, while Steven and Pearl looked down into the new hole.

Amethyst used her whip to throw a Centipeetle into the wall of the cave in the back. When it poofed, she looked at the others and picked her nose. "Um, you guys? These things don't have gems."

"That means there must be a mother somewhere nearby," Garnet said, walking up next to Isaac and Steven. A Centipeetle snuck up from beside her. Isaac was about to take it out, but she quickly punched without even looking, causing it to poof.

"We should probably find it before anyone gets hurt," Pearl said, still holding the Centipeetle she had as it struggle to break free.

This instantly got Steven. "Oh! Oh! Can I come?! Can I?! can I?!" He asked eagerly.

"Steven, until you learn to control the powers in your gem," said Pearl, and she snapped Centipeetle's neck, "we'll take care of protecting humanity, okay?"

Isaac saw one of the Centipeetle raiding the fridge and ran at it. Cutting it in half swiftly and poofing it, he then closed the door. With his right hand still on the door, he took a moment to pant and catch his breath. He could even feel his heart hammering in his heart. However, it wasn't over, as Isaac noticed something shining to his right. He turned head right, looking at the back of his right hand that he still had on the door of the fridge.

It was still glowing white, and that might only one thing in his experiences; there was danger near him.

"Cool!" Steven said, amazed at Isaac's glowing gem. "I didn't know it can do that! What does it mean?"

Isaac snapped his head left to look at Steven and the women with a glare. He quickly transferred the katana over to his right hand, and he pointed the tip at them. "It means it's time for you and your friends to get back," he said defensively. This surprised Steven and he backed away.

Pearl and Amethyst looked like there were ready to fight, up Garnet raised a hand. This got them to stop for a moment, before she walked up to Isaac. "Please, understand," she said to him in a calm voice, stopping a foot away from the katana. "I know you are scared and confused, but rest assured, we're not the enemy."

"Yeah?" Isaac asked doubtfully and was a bit of sarcasm. "And I'm supposed to take your word for it?" But then out of nowhere, the Onyx in his hand had lost its light. It was now back to its black form. When he saw it, he bewildered how fast it changed from recognizing them as enemies to friendlies. Knowing he wasn't it danger anymore, Isaac made the katana disappear. "Okay…so I guess you're not a threat."

"That was fast," Amethyst said with a fist on her left hip.

"My mom's gem only seems to glow when I'm close to danger," Isaac told her. "Like that monster I fought last night."

Pearl then stepped forward. "So where do all the gems you bubbled go," she asked, before placing a hand on her chin. "We'll have to get them and transfer them over to the Temple."

"Don't know." Isaac shook his head. "I looked everywhere for where they could've gone, but can't find them. But they never seemed to come back, so I figured that they're someplace safe." His expression turned serious as he looked down. "But that's not why I'm here." He then looked at them. "I'm looking for someone. Someone who can help me."

"Well, maybe we can tell you," Steven said with a smile. "It's our job to help all in need!"

"Only if they're in danger," Garnet corrected.

Pearl then asked, "Do you know this person?"

"I never met them, about two weeks ago I was told that if I ever wanted to know who my mother was that I should come here. That there would be a woman here in Beach City that would give me the answers I wanted," Isaac explained. The Gems however shared an uncomfortable glance. If this boy really was like Steven, then they had a pretty good idea of who the stranger before them was looking for.

"Ah, who was it that you're to find," Pearl asked.

"Her name is…" Isaac took a moment to think. "…Rose Quartz."

The moment Isaac said that name, the mood of the room changed to depression. The gems looked down with sad faces. However, Steven was more curious and surprised than sad. "You were looking for my mom," he asked.

Isaac could've felt his heart stop when he heard that. "Your…what?"

"It's true," Garnet said, placing a hand on Steven's hair. "We are Gems, an extraterrestrial species of magical beings." She then looked to the right, and Isaac followed her gaze. Hanging over the front door was a painting of a woman with very long and curly pink hair styled in thick, tube-like ringlets. She also had defined lips with a pale pink color, bright-peach skin, and a tall and heavy build. "Rose Quartz was the leader of our group, the Crystal Gems. Our goal is to seek the protection of the Earth guard humanity from evil." She paused for a moment. "Your mother, Onyx, was one of us."

Steven and Isaac gasped. "His mom was a Crystal Gem too?!" Steven exclaimed with stars in his eyes.

"You knew who my mom was," asked Isaac.

"Yes, but not that much," Pearl said. "She kept mostly to herself and like to be left alone. In battle, she was truly unlike anything I've ever seen. She was strong, swift, and brave. And like Rose, she was a natural leader who cared those under her command. With a little bit of luck on her side. There were many names give to Onyx, but only one truly stuck with her: The Gem of War."

Isaac and Steven, and even Amethyst were left in amazement. "Woah." Then a though hits Isaac and he turned to Steven. "Wait, if Rose gave birth to you, does that mean that she also…"

"She gave up her physical form to bring me into the world," Steven said, pulling up his pink shirt to show Isaac a pink rose quartz gemstone where his belly button should be. "Was it the same with your mom?"

"Yeah. That really all anyone would tell me," Isaac said with a shrug. "No one would tell me anything about my mother, either because they can't, or they didn't know that much about her to tell me. But what they did tell me was that she wanted me to have a normal life. I didn't know what they meant by that, but now I think I know now."

"Sooooo, what are we going to do," asked Amethyst.

"What do you mean?"

"Well, you've learned about your mother," Pearl started off. "You know about us and we know about you. You're also just like Steven. What do we from here onwards, uh… I'm sorry, we didn't even ask for your name."

"It's Isaac. Isaac Infinite." Isaac introduced himself. "And I figure I should be heading home. I'm…not really sure what I'm going to do then."

"Oh, I know!" Steven exclaimed with excitement. "You can join the Crystal Gems!"

"What?" Isaac asked.

"What?" Pearl asked loudly.

"That sound awesome!" Amethyst exclaimed with a big grin on her face. "It'll be way much cooler with a fifth member with us."

Isaac, however was unsure of it and scratched the back of his head. "I don't know. I never really came here to be a part of something," he told them. "Then again, I don't know what to do with myself now that I know the truth."

Garnet placed a hand on his shoulder, and Isaac looked at her. "How about we give you to the end of today to figure it out," she offered. "We're not going to force you into anything you don't want to do."

"And in the meantime, we can stay here and eat some popsicles," Steven said as he went over to the refrigerator. But when he opened the freezer door, he gasped, and his eyes widened with stars in them again. Isaac wanted to know what was going on, so he looked in the freezer too. When he did, he gasped, his eyes widened and had stars in them too.

The inside of the freeze was filled with Cookie Cat ice cream sandwiches. They were these delicious ice sandwiches that had half vanilla ice cream on the left and half strawberry ice cream on the right. All in between cookies that is shaped like a cat's head.

"Holy mother of Satan," Isaac whispered in amazement. "Dibs!" He reached in and grabbed one of the Cookie Cats.

"You like Cook Cats too," asked Steven as he followed his example and grabbed one too. Isaac then shut the fridge.

"Are you kidding me, I love these things!" Isaac looked at Pearl. "Where did you get these?! I thought they stopped making them!"

"Well, we heard that, too," Pearl said with a smile, "but we wanted to surprise Steven since they were his favorite, so…"

"We went out and stole a bunch," Amethyst proclaimed as she hopped onto the bar.

"What!?" Isaac shouted with a look of horror.

Pearl grunted at Amethyst angrily. "I went back and paid for them," she corrected.

"How does that make it any better!? You already stole the damn things!"

"The whole thing was my idea," Garnet then claimed.

"So, it was everyone's idea?!" Isaac exclaimed.

"Not really."

"All that matters is that Steven is happy," Pearl said, looking at Steven with a smile. However, Steven was too busy staring at the pink wrapper covered ice cream. Suddenly he began to sing.

"Oh, please don't sing that song," Isaac groaned in annoyance.

"Oohhhhh!"

"He's a frozen treat with an all new taste!"

"'cause he came to this planet from outer space!"

"A refugee of an interstellar war!"

"But now he's at your local grocery store!"

"Cookie Cat!"

"He's a pet for your tummy!"

"Cookie Cat!"

"He's super-duper yummy!"

"Cookie Cat!"

"He left his family behind!"

"Cookie Caaaaat!"

"Now available at Gurgens off Route 109!"

"God, I hate that song," Isaac grunted, while the Gems burst out in laughter and applauded.

"I can't believe you did this. I'm gonna save these forever!" Steven proclaimed. "Right after I eat this one." The boy then ripped open the wrapper and pulled out the ice cream sandwich. "Hello, old friend." He then bit into it.

Isaac followed suit and opened his Cookie Cat. He was about to enjoy it, when something started to glow. He looked, and his eyes widened in amazement when he saw it was coming from Steven's gem, under his shirt, as the boy chewed his desert. "Uh, Steven...what's going on with your gem?"

"Wha-?" Steven quickly lifted up his shirt and saw his gem glowing. "My gem!"

"Quick, try and summon your weapon!" Amethyst encouraged the young boy.

"I don't know how!" The gem was starting to lose its glow, causing Steven to panic. He grabbed his head and jumped between his feet. "Ah, it's fading! How do I make it come back?!"

"Calm down, Steven," Pearl said in a soothing voice, but Steven was anything but calm. "Breathe, don't force it."

"Yeah, and try not to poop yourself either," Amethyst joked.

"Please, don't," Garnet said.

Soon the gem's glowing faded away. The gems and Steven sighed in dismay, as the boy slides down on his butt.

"Ah, I was really close that time!" Steven puts the Cookie Cat he was eating away in its wrapper, before looking at Isaac, who was eating his ice cream while watching. "You're just like me, Isaac. How do you do it? Can you explain how to summon a weapon?"

"It's not that easy, Steven," he said with a mouth full of the last bit of Cookie Cat. He then swallowed. "I'm still trying to finger out how to do it too. Most of the time, I'm only able to summon it whenever a monster or some threat is near me." He then looked at the Gems. "Maybe one of you can explain how to summon a weapon?"

"Oh, I'll go first!" Pearl said in a singing voice. She then headed for the door of the house. "Follow me!" Steven excited ran after her, while Isaac walked.

As they exited the house, they stepped onto a balcony/deck and headed down some stairs. They then went down a grassy past that led to the beach.

After stepping on the sand, Isaac took a moment to look back at the house, but was instead left in wonder and astonishment by what was behind the house.

Carved and sculpted into the face of the cliff was a giant statue of a strange and yet beautiful woman. This was the face of the Crystal Temple. The giant woman had four pairs of arms with 4 arms spread out, and the other four converge around the house's sides, which rested on the figure's navel. Of the four spread-out arms, only the top-right arm had an intact hand and the broken-off remains of the other hands can be seen sticking out of the beach sands in front of the Temple.

"Whoa," Isaac said with amazement.

"Isaac, come on!" Steven called to him. Isaac glanced at the Temple one last time, and then ran off to join the boy and Pearl.

Later, Pearl took the two boys out to a hill that had a full-grown cherry blossom tree that was in bloom, with bright pink blossoms filling its branches and dark-colored bark.

As they walked up to the tree, Isaac stopped for a moment to admire the beauty of the area, as the petals falling continuously around them. "Woah," he breathed with a smile.

"Beautiful, isn't it, Isaac," Pearl said, glad that he was able to see the beauty of this place. "Out of all the trees on this planet, this is still my favorite tree."

Isaac nodded. "You know how to pick it." He then joined Steven on the ground and sat down on his knees.

"Pay attention to these petals, Steven and Isaac," Pearl told them. The two then watch one of the petals fall. "The petals' dance seems improvised, but it is being calculated in real time based on the physical properties of this planet." When it lands, they looked back at Pearl. "With hard work and dedication, you can master the magical properties of your gems and perform your own dance!"

She then placed her hands near her gem and it glowed, before she summoned her spear. With the handle and blade shorter than its original form, Pearl grabbed the weapon and the spear head extended, before she treadled it around and the handle extended. Afterwards, she placed the butt of the spear to the ground and did a pose.

Confident, Pearl opened her hand and let a petal off into it. "Like so."

"…So, we dance," Isaac asked, while Steven picked up a handful of petals.

After leaving, Isaac and Steven then head to Amethyst, who is behind the Big Donut eating a donut. While on their way, Steven's been trying to do what Pearl explained to them by tossing the petals into the air to get his gem to glow again.

When they arrived at the Big Donut, Steven did it again. Tossing the petals up and letting them fall. Amethyst and Isaac stood by and watched him. "Kid, you can stop now," Isaac said. "It's not going to work."

"Let me guess, Pearl told you the 'petal thing'." Amethyst guessed correctly.

"Yeah, she said that we have to calculate some kind of dance…" Isaac paused to think for a moment. "…wait, many it was something to do with trees."

"Listen Isaac, all that practice stuff is no fun," the short Gem told the young man, as Steven stopped to pay attention. Amethyst then stuffed her face with the donut and talked with her mouth full. "Whenever I need to summon my weapon, it just happens."

She demonstrated by putting her fist to her gem, causing it to glow, before pulling out her whip. Amethyst then swung it and sliced a nearby dumpster in half.

"See? Didn't try at all."

"But my weapon does come out whenever I need it," Isaac explained. "But it's only able to when danger is near. I'm trying to figure out how to summon it willingly."

"Huh?!" He was interrupted when some guy around his age came out from the back to the Big Donut. The guy freaked out when he saw the dumpster destroyed and dropped the trash bag he was carrying. "Again?!"

"Run." Isaac and Steven ran away.

With Pearl only confusing them, and Amethyst being of no help at all, Isaac and Steven made their way to Garnet. This, however, involved a long hike up the cliff to get to top, which is also the top of the Temple.

When they got there, the two humans stood in front of Garnet. To their left was a lighthouse, and to their right was the edge of the cliff. "So, I'm supposed to work really hard and not try at all at the same time," Steven asked the tall Gem.

"Yes." Garnet simply said.

"Wait, so which is it," asked Isaac.

"Both. Or..." Garnet raised her hands, showing Isaac and Steven her gems, before making the stones glow. "…you could link your mind with the energy of all existing matter. Channeling the collective power of the universe through your gem, which results in—" She swung her arms and hands around in a kind of dance, before summoning her gauntlets. "At least that's my way of doin' it."

"…" Steven and Isaac just stood there, still not understanding anything the gems were telling them. Then Isaac walked away.

"Well, that was a waste of time," Isaac grunted, making sure that he had everything in his backpack. After no real development, he figured that it would be best for him to head back home.

"No, Isaac! Wait!" Steven exclaimed, desperately wanting for the teen to stay with him and the Gems. "Th-There must be some way we can summon are weapons!"

Isaac placed his pack on the couch and looked at him. "How? We tried everything?"

Steven crossed his arms and placed a hand on his chin, thinking for a moment. "I think my best bet is to recreate what happened the last time my gem glowed. So..." He pointed and had Garnet and Amethyst go back to where they were when his gem glowed. "Garnet and Amethyst were here." He then pointed at Pearl. "Pearl and Isaac where next to the fridge." Isaac stood up and walked over to her. "Hmm. Amethyst, I think your arms were crossed?"

"Kid, I don't think it has to be completely accurate," Isaac pointed out.

Steven then opened the freezer and pulled out the Cookie Cat he was eating before. Discarding the wrapper, he said, "Then I took a bite of this Cookie Cat. Oh, wait! I sang the song first. Uh, he's a frozen treat, all new taste, interstellar war, now available at Ghurven's."

Silence as nothing happened.

"Aww, it was funnier last time." He pulled up his shirt to look at his gem. It wasn't glowing. After failing to understand what to do, Steven sighed. "Maybe I'm not a real Crystal Gem."

Pearl bent down next to him. "Don't be silly, Steven," she said to make him feel better. "Of course, you are."

"And you're fun to have around, even if your gemis useless," Amethyst joked. Pearl glared angrily at her. "I... mean, you're one of us, Steven. We're not the Crystal Gems without you!"

Garnet nodded.

"It took me a long time to learn the thinks I can do, Steven," Isaac said, pitching in to encourage the boy with a smile. "It wasn't easy, and I'm not sure if I've learned all I can do. But you've got the Gems to get you through it."

This was enough to ease Steven's doubts and he smiled. "Yeah, even if I don't have powers, I've still got... Cookie Cat!" He took a bite and enjoyed the treat. "Mmm, so good." But then, to everyone's amazement, his gem suddenly started glowing brighter than it did before.

After a moment, it glowed to the point where it was a bright flash of light. Isaac quickly covered his eyes to protect them from the light. When it was over, he removed his arm from his face and looked at Steven. His eyes widened, and he gasped.

Steven's weapon was finally revealed: a spiraled pink shield. The spiral on the shield was decorated with light pink rose thorns, and its center symbol is shaped like a rose.

The gems also gasped in shock, as they stared at the spiraling shield. "Steven, it's a shield!" Pearl whispered in amazement.

Steven opened his eyes, and he too was left in amazement. "Whoa, what?! I get a shield?! Oooh... yeah!" But as he cheered, he lost control and accidentally launched his shield. The weapon bounced and ricocheted around the room, before it stopped when it smashed into the TV.

"Holy shit," Isaac said with wide eyes, while Amethyst burst out laughing while Pearl put her hand to her head and groaned. "How did you do that?"

"Huh?" Steven looked at the ice cream sandwich he was eating. "Cookie Cat!" He then held it up and exclaimed happily. "I summon my weapon by eating ice cream!"

"That's stupid," Isaac said, as Pearl picked up the wrapper and looked at its ingredients.

"What's in these things," she asked.

"All the sugar a kid could want," Isaac joked with a chuckled, but stopped something else started to glow brightly. He looked down and saw that it was his Onyx glowing. "Oh no."

The ground suddenly started rumbling, causing the house to shake also. Isaac spread his feet to steady himself from tripping out. He looked at the window near the bed and saw the silhouettes of the Centipeetles crawling up the side of the house. However, they paled in comparison to a much larger figure that crawled on the outside of the house. The pink shield disappeared.

Isaac reacted by running to the door and swinging it open. He jumped onto the balcony and turned around. Looking upwards, he was shocked to see that the thing was a giant Centipeetle monster roughly thirteen visible dark-green segments that each bared one pair of similarly colored legs. The final segment at the end bared no legs, but what appeared to be a pair of mandibles. The head was composed primarily of a large pair of jaws/mandibles with an eyeball in the mouth. It also featured a green crystal protuberance at the base of the head that formed a broken horn-like structure, along with a flowing, light-cream colored mane immediately behind her head.

"Oh man," Isaac gasped with wide eyes, as the creature climbed up the Temple. He's only had to fight smaller monster and the largest of them was the size of a bear! This was beyond anything he's faced.

"It's the Mother!" Garnet exclaimed, standing next to Isaac. He turned his head to her and watched as she leaped up the statue towards the monster.

"Steven!" Isaac looked at Pearl as she and Amethyst were out of the house. "Stay in the house!"

"No way, I'm coming too!" Steven proclaimed and ran back inside for something.

"Do as you're told!" Isaac yelled at him inside. Garnet suddenly jumped down onto the roof of the house and then jumped off. The Centipeetle Mother followed after her, landing on the roof and then crawling off. Isaac ducked down to avoid the creature's body. When it passed over, Pearl and Amethyst jumped over it and joined Garnet.

Isaac stood up and looked from the deck as the Crystal Gems stood in front of the monster on the beach. The Centipeetle roared and shot out acid at them. The Gems dodged, and then ran over to hide behind one of the statue's broken off hands.

"I'm here!" Hearing Steven's voice shouting out, Isaac looked and saw the young boy running out of the house carrying the Cookie Cat freezer, which was filled with the ice cream sandwiches, and attracted to many extension cords. "I can help too!" Steven exclaimed, and was about to run down the steps. However, Isaac grabbed him by the arm and easily pulled him back.

"No! It's too dangerous!" He told Steven.

"But they're in trouble!"

"That's why I'm going out there," Isaac said in a stern tone. "You say here and don't do anything stupid!"

Isaac then leaped onto the railing and then jumped off them. Falling down to the ground, where he tucked and rolled upon landing. He quickly stood up and summoned his weapon and rushed at the monster. As the Centipeetle was busy spitting acid at the hand the Gems were hiding behind, the son of Onyx went to the one of the legs at the end and cut it off.

The Centipeetle shrieked in anguish, before turning around to look at Isaac. "YEAH, COME ON! OVER HERE!" He yelled at the bug and waved his arms, trying to get it away from the Gems so that they can get back into the fight. He then placed his left hand to his gem, and summon another katana. "Come on, ugly! Come this way!"

"Isaac, no!" The Crystal Gems called out to him, still hiding behind the now melting stone hand. The Centipeetle roared and turned its body around to face him. Now with two swords, Isaac was ready for battle.

With its mandibles drooling with acid, the Centipeetle lunged its head at Isaac. Isaac reacted quickly and jumped to the left. The monster snapped when he landed on his feet, so the human quickly slashed its head with the right sword and stabbed into where the mane came from with the left one. The mother cried out in agony.

It quickly brought its head back up, and sprayed acid at him. Isaac quickly ran out of the way of the attack. He looked up at the monster, and saw its head coming at him to bite at him again.

Isaac quickly jumped back to the right of its head. He then started slashing both katanas at it.

"He's actually doing it," Pearl said in amazement. Isaac was showing no fear as he leaped back from it snapping its jaws at him. "He'll need our help!"

But she quickly ducked back behind the hand when the back mandibles bit off the top of the fingers.

"Can we save ourselves first?!" Amethyst exclaimed.

Isaac looked at where they were for a moment, but this proved to distract him. The Centipeetle used its head to hit Isaac and knock him away.

The human grunted when his back hit the ground. He opened his eyes and looked up. The Centipeetle was approaching him, jaws dripping with acid, staring down at the young man with the intent to kill.

Garnet looked over the edge of the stone hand and saw him in trouble. "Isaac!" She would have jumped out and helped the human, but she was stopped when the Mother's pincers were going to clamp down on her. She was forced to hold them back from.

The Centipeetle reared its head back, its mouth flowing with acid. It was just about to spit it out at Isaac and kill him, when a large peddle was chucked at it. Then the rock hits the Mother in the head. It turned its head towards the person who threw it.

It was Steven! The boy planted the freezer he carried into the sand and then stood tall and proud against Centipeetle. "Leave them alone!"

"Are you crazy, kid!?" Isaac yelled at him. Was this all fun and games with the boy?

"Cookie Cat Crystal combo powers, activate!" Steven shouted before taking a bite of one of the Cookie Cakes.

The Centipeetle moved away from Isaac, and went over to Steven. Fearing for the kid's safety, Isaac yelled, "Steven, get out of there!"

Steven didn't listen and chewed the ice cream faster, before pulling up his shirt. He was expecting the shield to appear again.

But nothing happened.

"Uh-oh." Steven didn't have any time to move, as the Centipeetle lunged its jaws at him. "Aaaah!" He screamed, held up his arms, and shut his eyes.

STAB! STAB!

The Gems gasped.

Steven wasn't dead. And he wasn't hurt in any way, so he lowered his arms and opened his eyes.

Isaac had moved in front of him at the last minute to protect him. With his right foot holding down the lower mandible, as he held up the upper one with his katanas, Isaac held the jaws up, while using his left on the ground to push against the Centipeetle's head.

Steven looked at him with star-eyes amazement. "Isaac…"

Isaac glared hatefully at the eye of the Centipeetle. But he then noticed that the pupil of it was the gem: a circular in shape gemstone and colored light green with dark green contour lines surrounding the circumference of the gem, connecting to a circular shape.

Know where it was, Isaac came up with an idea that would be possibly the most reckless and idiotic thing he'll ever do. "Get away from him, you bitch!" He yelled, and stabbed his right katana right inside the upper jaw.

The Mother shrieked in total agony, yanking its head back.

"Woah!" Isaac's sword was pulled from the jaw and he was almost flung right out, but he hung on when he quickly dropped the katanas and grabbed onto the teeth of the lower mandibles. The Centipeetle closed its jaws to cut off his fingers, but Isaac quickly swung himself forward and let go before he lost his fingers. He then grabbed onto mane.

The pincer that had kept the Gems pinned down went away, as the Centipeetle shook its head to get him off. "We've got to save him!" Pearl exclaimed. Despite knowing Isaac for only a day, she couldn't let him die when they could help.

She and Amethyst were about to run over to help, but then Garnet stopped them when she grabbed their shoulders and pulled them back. "No."

"What?!" Pearl asked incredulously.

"I've seen much of his mom in his eyes," Garnet told Pearl.

Isaac had climbed the mane all the way to the top of the head. He summoned his katana again in a reverse grip, and raised it over his head. Suddenly, the Centipeetle yanked its head up, and the human was set flying upwards.

"AAAAAHHHH!" Isaac screamed as he was sent flying, before starting to fall. He looked down and saw the Centipeetle Mother waiting for him, jaws open as if it was going to eat him.

But Isaac saw this as an opportunity. He can still do this, and readied his katana.

He fell right into the monster's mouth and it shut close.

Suddenly the whole monster exploded into a giant green poof cloud.

Isaac impact with the sandy beach wasn't as hard, but he still grunted in pant when he landed on his back. He panted as he stared up at the afternoon sky, his arms and legs spread out, and his sword disappearing as his gem stopped glowing. After a moment he started to chuckle lightly, before laughing out loud and closing eyes. "I did it! I actually did it!" He shouted in victory, sitting up and throwing his fists up. "I am awesome!"

Steven and the Gems ran up to him. Steven then jumped on him and hugged him tightly. "Isaac that was amazing!" He exclaimed with a big grin. "You were so cool and epic! Swinging your swords, climbing on that monster!"

"Yeah, man!" Amethyst punched him in the arm, making Isaac yelp and rub his arm as he glared at her. "That was the coolest thing I've ever seen!"

"It wasn't! It was beyond reckless!" Pearl exclaimed in disapproval. "You were formless, wildly attacking, and you could have gotten yourself killed." Isaac looked down, before Pearl smiled. "But I will admit, it you were a very impressive fighter."

Isaac's head quickly looked at her with wide eyes. Garnet then stepped forward with the Centipeetle bubbled. "You were great, out there, Isaac," she said with what could be the first time he's ever seen her smile today. She tapped the bubble and it disappeared. "Your mother would've been proud."

Isaac stared at her in astonishment before smiling and nodding. "Thanks guys," he said, before standing up.

"Well, I guess you'll be going back home," Steven said with a sad face.

Isaac looked down at Steven, and then looked at the Gems. Garnet, Amethyst, and Pearl stared at him, wait for him to make a decision. He already got what he came here for, what else was there for him here?

Then again, what else was there for him out there? More traveling and hunting down monsters, without a real home? "You know, I'm still trying to learn things about myself," he said to the boy, who picked his head up and looked at him. "Why don't we finger it out together?"

Steven gasped with joy, before hugging his legs, which took Isaac by surprise. Amethyst laughed heartily, Pearl smiled and nodded, and Garnet gave him a thumbs up.

Isaac responded with a smile of his own. He had a feeling that this was going to be a good thing.

Later that night as the moon was fully out, The Crystal Gems were together, alone on at the top of the cliff, near the edge of the Temple. Garnet was standing at the edge looking out at the sea, Pearl was pacing back and forth behind her thinking, and Amethyst was sitting on the edge kicking her feet.

"So…the Gem of War had a child," Garnet said, finally bringing up the very thing that was on their mind.

"It'll be fun to have another human around to mess with. Hehehe." Amethyst said with a carefree smile.

"Amethyst, this is serious," Pearl said with a glare, stopping her pacing.

"Come on, P! Isaac's cool. He can fight. He's nice to Steven. And he saved our asses," Amethyst told them. Over the years, she started using the same vulgar language that human used. "Besides, his mom is the Gem of War!"

"There's a reason why she was called that."

"Yeah, the war Rose started to get Homeworld away from this planet." Amethyst shrugged. "But if what you said was true, then Onyx must have been awesome."

Pearl didn't respond and looked away. Garnet didn't reply either, only tilting her head down.

Seeing them act like that, Amethyst started to get a bad feeling and looked upset at them. "You…You did tell Isaac the true, right," she questioned them, standing up.

"We did," Pearl assured her. "But…"

"There was much about herself that Onyx didn't want Isaac to know," Garnet told Amethyst, and the other two Gems looked at her. "That's why she came to see Rose before his birth. Onyx wanted to spare Isaac from the pain that would come from knowing who she was. And what she was. She wanted Isaac to be human."

"But he's not just a human." Pearl sighed sadly. "We knew this day would come. When he would come looking for us. And now…It just doesn't feel right keeping the truth from him."

"Onyx knew that it can't stay hidden, and knew he'll find out in time. We don't even know the whole truth, only Rose did. For now, we'll allow him to figure it out. But it's like Rose said, who she was before doesn't matter, Isaac isn't her past, he's her son," Garnet recited their leader's words of wisdom. "And nothing would ever change that."

Pearl and Amethyst glance at each other unsurely, but in an action rarely seen from the two, they nodded in agreeance. They then joined Garnet at the edge, and stared out at the sea. As they did, there was now only one thing on their minds.

What will change, and what will stay the same?

AN:

And that ends the first part of "Gem of War"!

I know that the show has a lot of theorist that like to theorize things about Steven Universe, so if you want to for this fanfic, go right ahead. What is going on? Who is Onyx? And why does she not want Isaac to know about her? All will be answered, but I do like to see what you guys come up with.

Steven is the shield, and Isaac is the sword! As they are the main focus of the story, I wanted for Isaac and Steven's relationship to be something unique and special. I'm thinking about it starting out as somewhat similar to Church and Caboose from Red vs Blue, with Steven continuing to be himself, and Isaac getting annoyed by him, but does like him. And as the story goes on, their friendship turns into a brotherhood.

As for Isaac and Pearl, I'm going to take my time and have them truly grow closer before having them fall love.

For how I'm going to do each update, I'm going to do two chapters each time for this story, as the normal StevenUniverse episode is short, and it'll be better to just release two chapters at once. I'm sure as hell am not going to do any of the filler episodes that don't contribute to the story at all, as the creator seems to really like doing. If there's an episode you want me to skip over, let me know.

That's it for now. Please be sure to Favorite and Follow if you like the story, and if you want me to keep doing this story, then please leave a REVIEW. I would really appreciate it if you do. If you any questions or decisions you'd have for me, then please PM me.

Thank you for reading, may God bless you, and have a wonderful day.
