Yellow Diamond stood in her private chamber in deep thought as she read a tablet that her Pearl was holding up for her. "According to that Peridot's logs, before she betrayed me, she seems to have come across a Gem-human hybrid of some sort, possibly Rose Quartz and those Crystal Gem traitors." She put her hand on her chin in thought. "Call Blue Diamond." She ordered the Pearl.

"Yes my Diamond." She ran off to do her master's bidding.

"Yellow Diamond, what can I do for you?" Blue Diamond asked as her face appeared on the screen.

"Rose Quartz is alive, but has merged herself with some sort of human based on what I understand." She said.

"Interesting, but what is it that you need though?" She asked.

"I want that human to be shattered!" She slammed her hand on her chair.

"What do you suppose we do about it?" She asked remaining calm.

"I want to create a Gem-human hybrid." Yellow Diamond said smiling. "I want them to annihilate the other."

"Interesting idea, but how do you suppose we carry it out?" Blue Diamond asked stroking her chin.

"I'm dispatching a fleet of Rubies as we speak to go to the lost Earth colony and bring back a great human warrior." She responded.

"I will work on gathering the scientists and possible candidates for the experiment." Blue Diamond hung up the call while giving instructions to her Pearl.

A few days later…

The fifteen year old boy with yellow eyes and short, uncombed brown hair stood at five feet and six inches; his name was Aaron. He was at the arcade in his hometown competing at a game tournament. Aaron was fairly intelligent, skinny, and physically fit, and he had a passion for videogames that earned him respect from his peers.

At the same time, a ship carrying five Rubies crashed in the parking lot nearby with the ship still intact. They all exited their ship with a yellow diamond emblazoned on their chests. "Our mission is simple, find a great human warrior and bring them back to Homeworld." They all nodded their heads as they formed an orderly line and began exploring the new and unfamiliar territory.

Aaron was one health point away from losing his match until he saw his opponent's move. He quickly dodged their attack and used his special attack to finish them off. Everyone broke in to cheers when they saw Aaron win. "And the greatest warrior in the land is Aaron!" The announcer shouted.

"Greatest warrior." One of the Rubies repeated as they looked in to the arcade to see Aaron standing there. "He must be the one Yellow Diamond wants."

"Let's wait until he's alone. If he really is a great warrior then he'll be hard to beat with all of those minions by his side." The other Rubies all nodded their heads in agreement at the plan. Aaron walked out of the arcade with a trophy and a gift card to the arcade in his hands. He was headed for his bike when he was tackled by the five Rubies. "Hey, we got him!"

"What the hell are you guys?!" Aaron shouted as he pushed them off. He swung at one of them with the trophy hitting them in their gem and cracking it.

"Ruby!" They all shouted as they watched their friend fall. "We'll make you pay for this!" They all ran together performing Gem fusion and growing four times in size. They picked Aaron up with ease and squeezed him tightly. "Ha, we got him! Let's get him back to Homeworld." They made sure to render Aaron unconscious with one brute punch before defusing and carrying him on to the ship where he was tied up and put in a holding cell.

"Ughhh, where am I?" Aaron mumbled as he slowly opened his eyes to see that he was in some sort of cell.

"Earth warrior, we are transporting you to our planet of Homeworld." One of the Rubies said standing in front of him.

"What are you talking about? I'm not a warrior." Aaron was rubbing his head as he looked out the window and saw the depths of space. "And where am I?"

"You're on our ship, and we heard the other humans call you a great warrior." The Ruby told him.

"That was a videogame." Aaron said realizing their stupidity.

"Video-game? Is that some sort of battle simulation?" The Ruby asked.

"It was just for fun. Now let me go home!" Aaron shouted angrily at the Rubies.

"Sorry, but our Diamond must first have a word with you, Earth warrior." They sped up their ship as they got closer to their destination. Aaron banged on the walls for a bit until he grew tired and his headache returned; he fell asleep in the cell.

When Aaron woke up again, he was inside of some sort of containment unit with transparent green glass as he was carried forward. Several Gems were staring at him as they had never seen a human before. He looked down to see the Rubies carrying him towards some sort of glistening, stone castle. Aaron saw the increasing number of people following them towards the castle fascinated by the strange creature in front of them.

Aaron found it futile to bang on the glass as he just stood there until he was carried in to the castle while the other Gems returned to their tasks. "Set him down." A voice commanded. The Rubies did as they were told and ran off. Two Peridots walked over and began inspecting the tank and the human inside. "Welcome, brave human." The voice belonging to Blue Diamond said.

"Where am I? What do you want?" Aaron asked growing nervous.

"All answers come in good time." Blue Diamond said calmly. "Analysis?" She asked looking at the two Peridots.

"His vitals appear to be stable, but his knowledge core may need to be upgraded to our understanding." One of them said before being dismissed and bowing.

Blue Diamond waved her hand and made the tank open releasing Aaron. "Come along human." She said motioning for him to follow. Aaron reluctantly did so. "Why are you so angry?" She asked looking down at him.

"You freaking kidnapped me from my home planet, and you still haven't told me why." Aaron said glaring at her.

Blue Diamond smiled down at him. "You have been chosen for a higher purpose young warrior. You are going to be our new weapon against those traitorous Crystal Gems that reside on your Earth. Our research has led us to believe that we can infuse a human with the physical properties of one of our Gems.

"Are you going to explain these Gems to me?" Aaron asked.

"Oh, no that would take much longer than I have time for. We will simply erase most of your useless Earth memories aside from your name and basic bodily functions and replace them with all of our Gem knowledge." She explained like it was nothing.

"You can't do that. My memories mean everything to me!" Aaron shouted at her.

Blue Diamond looked down at him in anger. "You do not disobey your Diamond, tiny, insignificant human. You have no choice in this matter. I am your master, your Diamond, and your queen. You will obey me. Your thoughts, your memories, everything about you is mine now." She snapped her fingers as two Quartz guards appeared and grabbed Aaron by the arms. "Take him to the laboratory, so that we can get this over with and send him in to training."

"Yes my Diamond." They said simultaneously before dragging Aaron away.

They locked him in another chamber with another directly next to it; in that chamber was a blue girl with a triangular shaped gem in her chest. "Hello." She said nervously.

"Hi." Aaron said scowling as he looked up and saw what looked like a crystal dish above him.

"I guess we're going to be together soon." She said sighing.

"What do you mean?" Aaron asked putting his hands on the tank and staring at her.

"They're going to merge us together to create a hybrid of human and Gem. By the way, my name is Indigolite." She said.

"I'm Aaron, but why are they going to merge us together?" He asked banging on the glass.

"Some human on Earth can do it and is believed to lead the Gem resistance called the Crystal Gems. Homeworld wants to crush them once and for all by using their own secret weapon against them." She explained.

"How can you be okay with this?" Aaron asked. "You're going to lose your life."

"I do whatever I can to please my Diamond, and I'll live through you. I will be a part of you." She said calmly.

"Preparing memory implant." One of the Gems said pressing a hand on a panel. Aaron was blasted with a white beam of light and screamed in agony as he felt thoughts rushing through his head. "His current memories will be submerged in his mind and will resurface when triggered. Right now, he will only have his basic memories along with his new Gem knowledge. Transfer success."

Aaron looked up at them in anger still trying to comprehend everything in his mind. "Start the merge." Blue Diamond ordered.

"Yes my Diamond." The Gem said hitting another panel. Aaron shielded his eyes as he watched Indigolite turn in to a blue light that enveloped her gem and was absorbed through the point in her tank. Aaron looked up and saw the point in his tank glow the same shade of blue. Before he knew it, he was being blasted with the blue energy and screaming in agonizing pain. The stress his body went through caused his hair to turn gray.

"Increase power. He's resisting." Yellow Diamond ordered as the Gem increased the power. Aaron screamed louder as his eyes turned a sapphire blue and a triangular gem formed in his upper chest. The machine shut off as Aaron fell to the floor with a thud. "Excellent." She said clapping her hands slowly.

"I won't serve you. This is unjust." Aaron spat as he forced himself to stand up.

"You respect your Diamonds." One of the Quartz guards said knocking him to the ground.

"Just get him to training." Blue Diamond said hovering away as Aaron was dragged off by the guards and locked in a large, empty square room.

"Time for training, rookie." He heard a voice tell him. "Pull out your weapon. The longer you make us wait, the longer we make you suffer." She hit a button electrically charging the floor and shocking Aaron.

"How do I pull out my weapon?" Aaron asked glaring at the screen.

"Harness your energies and focus!" She shouted pushing the button once more. Aaron closed his eyes and tried to ignore everything around him. He could feel something as he saw his chest glow then stop. "So close." She said hitting the button once more.

"That's not helping." Aaron glared angrily at her.

"I beg to differ. Now, again!" She shouted pressing the button once more. Aaron tried once more and could see the outline of what looked like a spear in front of him. He kept his focus until it became solid. Aaron reached out and grabbed it. The handle was a solid dark blue color while the spearhead resembled his gem's texture and color, but a bit more transparent. "Good, now do it again." She ordered. Aaron repeated the process until he could form his spear with his eyes open and with minimal effort. Of course by this time, he had been shocked repeatedly and was clutching his chest in pain.

"What now?" Aaron asked breathing heavily.

"You rest now, human. Your energy levels are low." The lights in the room dimmed. Aaron sighed as he laid down on the cold floor and fell asleep.

He wasn't sure what time it was when he woke up, but someone was poking him with a sword. "Get up and fight human!"

Aaron groaned and rubbed his eyes as he stood up. He was immediately knocked back down. "What do you want?" Aaron asked forcing himself back up.

"A fight!" The Gem shouted knocking him to the floor once more. Aaron forced himself back up and formed his spear in his hand. He swung at the Gems who blocked his attacks. Aaron also had to dodge their attacks, and no matter how many of them he seemed to defeat, more would always appear. Aaron kept practicing with his staff swinging it in a fluid motion that could destroy several Gems at once. Then he saw a beam of energy shoot from the staff and blast one of the Gems back. Aaron smiled as he spun the staff in his hand and then aimed it precisely shooting another Gem back.

"His training is coming along well." Yellow Diamond said looking at a screen. "Let him go a few more rounds before being armed and shipped back to Earth with his mission."

"Yes my Diamond." She said as the call hung up.

"Where'd all the guys go!?" Aaron asked as his spear disappeared.

"You are to report to the armory. Now!" The Gem shouted as a door slid open. Aaron walked through it and found himself in a room full of tools, weapons, and armor.

"I'm Bismuth, kid. I've been told that you need gear for your trip. The Diamonds gave me your measurements, and I looked in to some of that weird Earth stuff. I think that you'll like it." She walked over to a lockbox and opened it pulling out a dark gray metallic armor that appeared to be futuristic. Aaron put on the legs followed by the boots, then the chest plate, the wrist gauntlets, and finally the helmet which had a dark blue visor that only he could see through. The chest plate had a see-through piece in the center that showed his gem. "You like it?" Aaron nodded his head throwing a punch at the wall and cracking it. "Nice power. Blue Diamond wants to talk to you. Better get going before she gets mad." Aaron nodded his head and ran down another hall until he found himself in her chamber once more.

"I see that my Bismuth outfitted you well. Just one more thing." She handed something to her Pearl who walked over to Aaron and grabbed his left arm and embedded something inside the gauntlet. "This is a direct line to the Diamonds. You use it when you're mission is complete."

"What is my mission?" Aaron asked crossing his arms.

"Yellow Diamond will inform you. Now aren't you forgetting something?" She asked glaring at him.

One of the guards hit him and knocked him to the ground. "You bow to your Diamond and you acknowledge that she is your Diamond."

"I won't bow to her." Aaron cursed as he was thrown against a wall.

"How about now?" The guard asked.

Aaron walked over to Blue Diamond and kneeled in front of her. "I apologize, my Diamond. Will you have someone escort me to Yellow Diamond for my mission?"

Blue Diamond smiled at the obedience. "Guard, take him to Yellow Diamond." Aaron stood up as he was escorted from the room.

Aaron stood in Yellow Diamond's chamber in his full armor as he knelt in front of the Gem Goddess. "Your mission is simple; destroy the other Gem-human hybrid and the Crystal Gems. Then you are done and may return to Homeworld. Any questions?" She asked looking at him.

"Not about my mission, but about me. Why do I not need to eat? Why have you not taught me about shape shifting? And why have you not taught me about fusion? All of these things were put in my mind, but you have provided no clear explanations." Aaron said looking up at her behind his visor.

Yellow Diamond looked down upon him. "We have temporarily suspended your body in a stasis that will end once you return to Earth. As for shape shifting, it is a disgrace to your physical form and holds no place in my court. The same goes for fusion. Two weak insignificant beings coming together to form something even more flawed is pathetic and should only be done in battle as a last resort. Other than that, it is a waste and completely unacceptable in my court." She looked at Aaron who nodded his head, but behind his visor showed intrigue. "I have a crystal fighter arranged to take you to Earth where the last Gems we sent there were defeated in disgrace by those worthless Crystal Gems."

"Thank you my Diamond." Aaron stood up and bowed before leaving the palace and being escorted to a ship hangar. He walked up the landing hatch and closed it behind him as he entered the cockpit. His Gem knowledge informed him of how to read Gem and pilot a ship as he powered it on. "They told me I came from Earth, but I remember almost nothing about it." Aaron thought to himself as the ship started flying to the programmed coordinates. "No matter, I will destroy the Gem-human hybrid and earn the respect of Homeworld and my Diamond." Aaron accelerated the ship ready to head to Earth for his mission.
