Steven Universe the Black Gem

Chapter 1: Old Scars

It has only been a week since Jasper and her Gems attacked the Crystal Gems. Beach City has been recovering well from the damage done to it when the hand shaped Gem ship crashed and then exploded with some of the debris landing on buildings only causing minor damage to the area. Steven was reading a book while Amethyst was eating a donut while sitting on the counter, Garnet was inside the temple looking on something, but Pearl couldn't be found. Steven looked up from his book when Garnet came walking out of the temple.

"Where's Pearl? I haven't seen her all day." Steven asked as he looked at the other two Gems.

"It's just the anniversary between her and another Gem." Amethyst answered as she looked at the half-human half-Gem.

"What was her name?" Steven asked as he looked at the fusion Gem and single Gem while walking up to the fusion Gem.

"His name was Obsidian. He was a powerful Gem." Garnet stated as she knelt down to talk to Steven face to face.

"What do you mean he was powerful?" Steven asked and then turned to the door with the others to see Pearl walking in with tears in her eyes.

"You feeling ok, Pearl?" Amethyst asked as she looked at the older Gem.

"I'll be fine." Pearl answered as she wiped some tears from her eyes.

"Hey Pearl." Steven stated to get the attention of the pale Gem.

"Yes Steven." the white Crystal Gem replied as she looked at the group's young charge.

"Who was Obsidian, and what was he like?" Steven asked causing Pearl to look at him in shock while Amethyst face palmed and Garnet to open her mouth in shock.

"Steven, you shouldn't have asked!" Amethyst stated as she fell backwards onto the counter.

"It's alright. Obsidian was a Gem that was a great warrior and scholar, but he was mostly a scholar. He also had the power to imprison other Gems into his own gemstone. You could say he was a living prison." Pearl answered as her gemstone formed a hologram of a black figure fighting three grey figures then changed to show the same black figure in what looked to be a library, then change again showing the black figure seemly absorbing a grey figure.

"He sounds unbeatable!" Steven exclaimed as his eyes light up with excitement.

"Most thought he was and feared him, but I got to know him for whom he really was. He was most likely the smartest Gem there was. He was such a great warrior because he was able to predict what his opponent was going to do. He was one of the best rogue Gem hunters." Pearl stated as she released a sigh.

"So what happened to him?" Steven asked as he started to get a bad feeling when he heard Pearl said he went after rogue Gems.

"When Rose and the rest of us formed the Crystal Gems to fight off the other Gems, he was split on what to do. His gemstone was not the most stable. Nor was his physical form very stable do to his gemstone being unstable, but his mind was very powerful and he had a powerful sense of duty." Garnet started to say as she rubbed her three eyes.

"What do you mean? What happened to him?" Steven asked as he started to freak out from what he was hearing.

"He went crazy and started to attack every Gem he came across and then imprison them in his gemstone. We had to send him off world to keep him from most likely destroying everything on Earth." Amethyst answered as she dropped the answer like she did when they talked about the Laser Light Cannon and Greg.

This caused Pearl to start tearing up again and said she was going to be in her room while she hid her eyes with her arm and ran to the temple gate.

"How close were Pearl and Obsidian?" Steven asked as he looked at Garnet sad for his fellow Crystal Gem.

"I believe Greg would have called them soul mates." the fusion Gem answered as she cupped her chin.

"They were that close. No wonder she seems so hurt." the young boy stated as he started to see why the older Gem was hurt so much.

"Personally I hope he never comes back. We have no way of stopping him and we're out of methods to send him off world now." the youngest of the full Gems stated as she shuddered at remembering how he went through waves of Gems like they were nothing.

Garnet suddenly stood ram rod straight as she looked to the door and ran to it. The others ran to her and looked up into the sky like she was and saw what looked like a shooting star falling near the city. Garnet seemed to sweat as it changed direction and seemed to be heading at Beach City.

"This can't be good!" Steven yelled as Pearl suddenly ran out and jumped over them then ran across the beach as the object started to skim across the water surface.

The others quickly ran over to their friend as the object suddenly stopped in front of them revealing it to be some sort of sphere of fire about as big as Garnet was tall. It continued to spin in place a good 5 feet off the ground with heat coming off of it like a summer heat wave. Amethyst knew it couldn't be Peridot since her escape pod most likely landed somewhere in Canada. The fire sphere started to get a crowd to form around it and the Crystal Gems were starting to get scared that it might be some kind of bomb. The sphere suddenly stopped spinning to show a blackened metal sphere with some cracks in it.

"What is this thing?" Ronaldo Fryman asked as he took his phone out and took a picture of it.

"Garnet, please tell me this is just a giant gemstone." Amethyst begged as she looked at the sphere with slight panic in her voice.

Garnet summoned her weapons causing the others to do the same and getting the crowd to take some steps back. The cracks in the metal sphere started to get bigger and bigger with what sounded like someone saying 'I have work to do.' The sphere exploded outwards as a figure just as tall as Pearl landed on the ground. His skin had a grey complexion while his slightly spiky hair was onyx black. He wore a black muscle shirt that hugged his torso and had baggy black pants. On his forehead is a black gemstone that looked to be about an inch in radius and looked to be made from rough black obsidian. As he moved up, everyone saw that his eyes' were black and his irises were grey. Pearl dropped her spear and fell to her knees as she looked like she was about to cry again.

"Obsidian is that really you?" the arguably smartest of the Crystal Gems asked as she couldn't keep herself from trembling from happiness or from fear.

He looked down towards Pearl and smiled before his entire body seemed to glitch and he reached up to his gemstone. A grey light started to come out of it while he summoned his weapon. Garnet and Amethyst knew that Pearl was too emotional at the moment to be able to help them. Obsidian summoned forth a weapon that looked like a black halberd. He spun the weapon around for a second before stopping it and holding it above his head with both hands.

"I must hunt down every rogue Gem. No exceptions." Obsidian stated as he readied his pole weapon for battle.

"We are the protectors of this world and all on it. We will protect it from everything that means it harm and that includes you." Garnet replied as she readied herself to fight a Gem that never lost a fight against small numbers.

"Why should I care about this planet? The only reason I'm here is to capture all rogue Gems." Obsidian stated but seemed to glitch again for some reason before going back into his battle stance.

"We're doom!" Amethyst yelled as she bent herself into a ball.

"Wait I have an idea, but we're going have to get Peridot! You three find her! I'll hold Obsidian off! Go!" Garnet yelled as she fired one of her gauntlets at the living jail.

"Garnet, you know I can defend myself against him, and why do we need her!?" Pearl yelled as she watched the two starting to fight.

Obsidian was using his wisdom to predict Garnet's attacks while Garnet was using her future vision to see what he would do next and was able to dodge his attacks, but he started to see through this and started to change how he usually fought. This caused the other Crystal Gems to quickly turn around to ask Greg if they could use his van before they heard laughing causing the crowd to part to show the very Gem they were about to look for.

"Now with this weapon, I'll be able to finally get the Cluster and take it back to Homeworld." Peridot stated as her left hand was a screen showing something that looked like advance math.

Seeing her caused the crowd to move even more back while Ronaldo took pictures of her on his phone. Peridot sent a glare at the Fryman then looked back at the Crystal Gems.

"Why did you call Obsidian a weapon, and why are you here?" Pearl asked as she summoned her spear and pointed it at the Homeworld Gem.

"I'm here to try to find a ship that is still capable of taking me back to our world, and that is Obsidian of the Black Gem Twins. Onyx will reward me for bringing back his brother. Then we'll return and finish what should have happened over 5,000 years ago." Peridot answered as she pulled out a Gem Destabilizer.

"He's staying with me and his friends!" Pearl yelled as she rushed the green Gem to stab her with her spear.

Peridot dodged the attack while trying to bury the weapon into Pearl's chest but her arm was caught by Amethyst's whip pulling it in a different direction. Before the Homeworld Gem could recover, Steven grabbed the destabilizer and broke it. The three Crystal Gems thought she would ran away now but were surprised when her fingers on her right hand started to spin around with energy coming off of them.

"Do you really think I'm totally defenseless? I was made to be, as these humans would say, a next generation Obsidian. The only reason I'm not is simply because I chose to focus on my intelligence over being a brute like Jasper and Onyx himself. I can destabilize any Gem with my blaster alone. Much better since they then can be questioned later." the Homeworld Gem stated as she gained a wicked small as she started to take aim with her right arm still using her left for her math equations.

"You're the reason why the Prisoner Transport Pod we placed him in came back! He went crazy because he can't tell who is rogue or not. When we started the rebellion, there were only the Gems and the different task forces! He won't stop until every Gem has been imprisoned in his own gemstone and transported back to Homeworld!" Amethyst yelled as she couldn't believe Peridot's reasons.

Peridot fired a blast of energy at the Crystal Gems aiming for Amethyst's gemstone but was blocked by Steven and was unaffected by it.

"What are you!?" Peridot yelled as she seemed to forget the others and simply tried to force Steven to go back into his gemstone.

"I am Steven Quartz Universe, son of Greg Universe and Rose Quartz! I'm half Gem and half human!" Steven yelled as his gemstone started to glow as his mother's shield appeared in front of him.

Before Steven could take the shield and fight the Homeworld Gem, Garnet was able to surprise Obsidian and punch him hard enough to send him into Peridot.

"What are you doing? Get them!" the light green Gem yelled as she got up but then her screen started to flash red saying that there was something wrong.

"I must hunt down every rogue Gem. No exceptions." Obsidian replied as he change targets to the Homeworld Gem.

"I'm not rogue, they are!" Peridot yelled as she backed up from one of the most dangerous Gems that ever formed.

The black Gem went to slash the younger Gem across the chest but missed since he never saw how she fought before. Peridot fired her weapon and was able to hit Obsidian causing him to lose control of his physical form for about a second, but what surprised everyone the most was that a blacken gemstone came flying out. At first a body started to form with the gemstone on the Gem's back, but then the body started to break apart with the gemstone shattering.

"What happened?" Greg asked as saw what looked like a Gem dying before his eyes.

"Every Gem has been imprisoned in him for too long. If we force him back into his gemstone every Gem will be freed and then they'll die." Garnet stated as they realized that every friend that he imprisoned into himself was now good as dead.

"Let me go!" everyone heard the voice of Jasper as the body of Malachite with chains of water around her arms and torso came ripping out of the ocean.

"Large scale threat found. Eliminate." Obsidian stated as he ran from Peridot and towards the unstable Gem Fusion.

"No get away from me!" yelled the voice of Lapis as the Gem hunter got closer to her fused form with the fusion starting to break completely do to her weakening and her panicked mind wanting to get away from the hunter.

Obsidian jumped into the air and seemed to fly while dodging water hands that reached out to him. He started to slash the Gem Fusion with the intent to send the two fused Gems back into their gemstones. Before he could strike at the large Gem one more time, the fusion ended with the two Gems landing on the ground with grunts of pain. Obsidian didn't know who to go for first and was very confused. This gave Peridot enough time to aim both of her blasters at the Gem hunter and blast him with enough power to force him back into his gemstone. Before he went back into his gem, what looked like hundreds or thousands of blackened gemstones came flying out of his gemstone and the same thing happened from before, but with two gemstones with color. One looked to be a blue diamond cut into the shape of a radiant while the other one looked to be a white diamond cut into a princess.

"Who are those two?" Steven asked as Pearl quickly grabbed Obsidian's gemstone and then jumped back to the others.

"Those are Blue Diamond and White Diamond. I was wondering where they went after Obsidian went out of control." Garnet stated as the two Gems shot out of sight in land.

"We are leaving. Now!" Jasper yelled as she ran past everyone to get to Peridot and to get to their missing leaders.

"You're not going anywhere." Lapis stated as she started to use her power to control the ocean water to grab the other Gems that where trying to escape.

The two Gems where able to avoid the blue Gem's attacks while avoiding launched gauntlets from Garnet as she was trying to hit them.

"They will be back, but Onyx will be coming now with Obsidian's awakening. We need to get ready for war." Garnet stated as she looked to see Pearl holding Obsidian with all her life.

The other Crystal Gems helped Pearl up and went back to the temple to get ready for the arrival of the most ferocious Gem that has ever formed. While they went to the temple Lapis walked into the ocean waiting for when she would be need while regaining needed strength.
