Hi. So this is my first Steven Universe story. And my first in a long time. Too long if you ask me. I won't get into why, it's personal. But I plan to post something every few days know. So without further delay lets get to it.

And as a side note this takes place after 'Full Disclosure'.

An Unexpected Guest

Location: Science and Research Building 1 (Homeworld)

"So in conclusion, the subject is responding well to the tests ma'am," said the small blue gem, looking at the data on her data recorder.

"Good. Once it is fully operational those Crystal Gems will regret the day they were made," said the larger, yellow figure.

"However, the defect is still present. We have tried to treat it, but nothing works."

The larger figure turned around and looked out her window, deep in thought.

'I need this in order to eliminate those annoying pests. But if this defect continues to persist we will need to start over. And considering even our best scientists agreed this success was a fluke, that would not be good.'

She turned back to the small gem and and said, "Erase its memories and replace them with new ones. Something sad, like it was in the war and Rose and her allies killed its friends, or something like that. And once that is in place, we will make our move. Know go Topaz."

The last part was said with such malice that it would have made the small gems spine shiver, if she had one. She quickly walked out saying, "Yes, Yellow Diamond. Right away."

'Well. Know that this is almost complete, I will finally be rid of them. And hopefully it will succeed where Jasper and Peridot have most likely failed,' she thought, laughing.

As the Topaz walked down the halls she could literally feel the tension and stress leave her body. She hated being the one to report to Yellow Diamond about this. But that was the price of being the senior scientist, and part of one of the biggest projects in Gem history.

She stepped on a platform at the end of the hall and pressed the down button. It went down one floor, and she headed straight for the only room on the floor.

'At least it's never a long walk from here to there.'

Upon opening the door she saw her assistant working on a computer. As well as several other gems on the lower level standing around a large glass tube filled with restraining gel and their subject.

"Hello Sunstone," she said to her assistant.

"Hello. What did Yellow Dimond say?"

"Always to the point. Well I have good news. It is almost time to put our work to use. Our orders are to wipe its memory and then implant a new one. Nothing complicated, just something to make it hate the Crystal gems. Then it will be time to unleash it," she replied, looking at the figure in the tube.

"Really. That is good news. Well we best not delay. I will initiate the mind wipe now."

Sunstone was nervous, she had come this far and this development meant she would have to move faster then she thought. She started the process and looked at Topaz. She was watching the tube very closely.

Sunstone carefully reached into her boot and pulled out a small remote. With her finger on the button she watched the screen. When the wipe was done and the screen flashed the word 'Complete' she pressed the button and put the remote away.

Just as Topaz was about to speak there was a loud noise that shook the building. A few of the scientist lost their balance and fell but it was the message over the intercom that got to them.

'Attention everyone there seems to have been an explosion on the lower levels of the building. I would like to ask that you all please evacuate the premises immediately.'

Everyone else in the room was gone by the time the message was done. The only two left were Topaz and Sunstone.

"Topaz, get out of here!"

"No I need to save my research."

"Don't worry about it I'll handle it. Just get out."

"No! This my greatest work. I will not risk it being destroyed, or worse, taken by those rebels."

It was clear that she wasn't going to leave. That means Sunstone had to take drastic action to ensure the success of her mission. Without a word she touched the gem on her hip and drew her dagger. She walked over to Topaz, placed her hand over the gems mouth, and stabbed her.

The gem started to glow, and was quickly pulled into hers. Sunstone put her on the ground and pierced her, breaking her gem into several pieces.

She stood up and pressed a large red button on the console. This sent several pulses of high voltage electricity through the subject, causing it to revert back to its gem. Sun hopped over the console and ran to the tube.

With a quick punch the glass broke and the gel spilled all over the floor. She grabbed the black stone, put it in her boot, and ran for the exit.

Location: Unknown (Home world)

She managed to get away undetected, and ran to the place she was instructed. She took the gem out of her boot and bubbled it. Placing it near the bench, she grabbed the transport pod and the video recorder.

She placed the bubble and recorder in the pod and closed it up. She picked up a controller and started setting the location.

"Sector HR, Coordinates X 52, Y 84. Planet Earth, home of the Crystal Gems."

She opened a small hatch, just big enough for it to get out. She was about to press the send when she heard a banging on the door, fallowed by an angry voice.

"Open this door. We know it was you. We saw the security footage. You set and detonated the bomb, shattered the scientist in charge, and stole the subject. You have five seconds to comply."

She immediately pressed the controls and the pod started to float up. It went through the hole and remained stationary for a second. Then it shot up into the sky and into space going close to the speed of light.

That same instant the door was broken down and several large gems holding weapons rushed in. Sun didn't put up a fight, her job was over. She could be shattered for all she cared. Her job is done.

"Where is it?" Yelled a gem that was clearly in charge.

"Out of my hands and out of your reach. You won't get anything out of me."

"We'll see."

Location: Beach City (Earth)

Steven yawned as he stretched his arms and rubbed his eyes. He hopped out of bed and walked downstairs. Normally he would have seen Garnet, Amethyst, and Pearl in the living room, but he didn't see them.

He would have questioned this but his stomach growled so he went to the kitchen for some breakfast, but found a note on the counter.

'Dear Steven,

We got a lead on where Peridot is. We would have taken you with but Garnet said we kept you out too late last night and to let you sleep. We will see you soon, hopefully.

Love you, Pearl'

He put the note back, shrugged, and got his breakfast. Sat on the couch, turned on the t.v. and ate his cereal. When he was done he put his bowl in the sink. Completely unaware of the danger heading his way at 600 million miles an hour.

He went upstairs to get a set of clothes. Went to the bathroom to wash up and get ready for the day. When he was done he put his pajamas in the hamper.

Suddenly, he heard a loud crash outside the house. He ran outside to see what happened. From the porch he saw a large hole in the beach. He ran down the steps and to the hole. When he got there he looked down and saw a large metal ball.

Steven slid down the slope and slowly approached it. He knew the best thing to do would be to wait for the gems, but he had a feeling in his gut that he needed to take a look. And that decision would prove to be a very dangerous one, but also very necessary.

The ball was orange, the size of a bowling ball, and smooth. He touched it, and instantly pulled his hand back. It didn't hurt him, but he felt something weird. He touched it again and felt a sense of life in it.

"Wow. It's like there's something in it. Something... lonely and scared. What could be in this thing?"

He climbed up the slope and looked around. No one had come to the beach yet, so he assumed no one was. He slid back down and started to think.

"Well, I guess there's no reason to just leave it here. Mind as well take it to the temple. I just hope I can lift it."

He grabbed it and started to pull. To his surprise it lifted of the ground very easily, causing him to fall backwards. He looked at it for a second, then turned around and started crawling up. It took longer then before, but he did it. He dusted himself off, picked up the ball, and ran for the house.

Steven put the ball on the living room table and sat on the couch. He watched it for a few minutes trying to think of a way to get it open. Thinking of nothing, he picked it back up and took a closer look at it.

It was just an ordinary, metal ball. Until he got a closer look. On one 'side' of it was a weird mark, only slightly lighter then the rest of it. He turned it and realized it was a hand. He looked at his, then back at it.

Steven took a deep breath, held it, and put his hand on the mark. There was a small flash and a mechanical sound as a portion of the ball lifted up, revealing it was half hollow. And inside, Steven saw what looked to be a black box, and a bubble with a gem inside.

He looked at it, now seriously considering whether he should have brought it into the house. He gently lifted it out, being careful not to pop it. It was about the size of an average gem, black as coal with purple streaks, and shaped like a square.

Carefully, he put it on the table, then reached for the box. It was small, rectangular, and could be opened. He flipped the cover, and saw a screen on one part, and a few buttons on the other part. He was about to press one, when he heard a pop.

He turned around and saw the gem in the air, glowing. But instead of the usual white light, it was a purplish black. The light started to change shape, into the form of a person. When it stopped Steven was both confused and afraid.

It was just taller than Pearl, slim but still with some muscles. A blank expression on its face. It wore a form-fitting, black jumpsuit, had jet-black hair down to its shoulders, and completely black eyes. But the confusing part was that instead of being a she like gems were supposed to be, it was a he.

It just stood there for a few seconds. It looked around the room, finally focusing on Steven. This made Steven back up a step, not knowing what the gem was going to do. However, it didn't have time to do anything just as soon as it formed, it fell over, unconscious.

Steven waited to see if it was faking, but when the gem didn't move he took a few steps towards it. It still did nothing, so he took a few more steps. After doing this two more times he was standing right over it. He nudged it a couple times.

He didn't feel right just leaving it on the ground, even if it looked scary. So he hesitantly grabbed its hand and carefully dragged it to the couch. He then, just barely. lifted it up, and set it down. Breathing heavily as he sat down next to it.

So Steven sat there for an hour and a half watching t.v., occasionally looking over at him to see if he was awake, always ready to bring out his bubble if he needed it. Finally, after the what felt like an eternity, he heard the warp pad. Suddenly realizing he didn't even think about what to tell the gems he became nervous.

He ran over to them with a somewhat faked smile and attempted to distract them, "Hey guys! How did it go?"

"Hi Steven. It didn't go well. Peridot got away," said Pearl.

"Well how about we go look some more. Come on. Let's go, away from here," he said while trying to push Garnet to the pad.

They all looked at him, knowing something was going on. Garnet pushed him back a little and folded her arms. Each of them knew he was hiding something. But Garnet was the one who was going to get it out of him.

"Steven, what are you hiding from us?" she asked.

"N-Nothing," he replied, looking everywhere but at her.

The three of them looked at each other, not falling for it. But when they looked back to Steven, they were horrified to see a figure dressed in black standing behind him.

So there it is. Please leave a review for me to see if there is anything I can improve on, and be sure to tell me what you think. Your reaction will be what determines if I proceed with this story. Good reaction, more frequent updates. Bad, I may discontinue it.

And as one last note I will be taking requests for ideas for chapters, but only after chapter 5. I want to build his character first. And if you're an anonymous reviewer, give me some way of giving you the credit for the idea.

See ya.
