Disclaimer: I do not own Percy Jackson and the Olympians. All rights goes to Rick Riordan. If I did copy someone's fanfic. I'm extremely sorry. I didn't know or I didn't come across that story yet. I read a lot of fanfic like 'Percy disappearing and a hundred or thousands of years later, he goes back to Earth to save the Olympians blah blah blah'. Once again, I do not own Percy Jackson and the Olympians. If you do not like this fanfic, stop reading and don't review of how bad my grammar is or whatever. I'm working on it. Just keep your bad comments to yourself but if you have good ones, click review at the end of this chapter. By the way, this is after the Heroes of Olympus series. I know Rick Riordan hasn't finished yet but I'm using my imagination. Thank you for your time. Enjoy the first chapter.

Prologue

Percy was so happy when he found out that he was going to have a half-sibling. He didn't know that things would turn upside down. After Poseidon sent Andrew, Percy's half-brother, on a quest with Annabeth and Will, things changed. Once they came back safely from their quest after killing one hellhound, Andrew got all the attention. Percy didn't really matter. What matters most to him was his friends.

One day, Percy caught Annabeth cheating on him with his half-brother Andrew. Percy couldn't take it anymore so he decided to leave. He left a note for Grover, Thalia, Nico and his full sister, Ariana before he left. That was actually hundreds of years ago after the Prophecy of Seven defeated Gaea and now, she's rising along with the other Titans to conquer the world.

Chapter 1

3rd Person POV

"I believe you succeeded on your mission, sir."

"Yes, I believe it has."

Who is he? I'm sure you're wondering who he is. He's Percy Jackson. Son of Poseidon. He's been missing for over 700 years. He's now Chaos' personal assassin and the commander of the Chaos' troops. He's also known as Alpha; meaning 'the beginning'. He wears a black hooded Assassin's cloak with sea-green trim. Perfectly engraved silver armor, silver gauntlets with engraved silver hidden blades that pop out when he wanted them to, and black assassin pants on. Brown knee high boots on with engraved armor on the tops of the boots that are blessed to not make a sound. A beautiful silver four foot long double edged sword strapped at his side. Two feet long duel blades strapped on his back and throwing blades strapped on his belt. He also wears black leather gloves that matches his suit and has even mastered the bow and arrow. He has a beautiful bow that would rival Artemis' bow. The bow automatically reloads just like the hunters' bows.

He wears a silver mask that covers the scar on his face. Percy was hit on the face by an ancient beast and was able to cut a large scar on the left side of his face shaped like an inverted Eastern Cross. People thought that the mask was just to hide his identity but the real reason was to cover up the scar.

He just finished his mission to assassinate Gollum. Gollum sneaks into people's houses at night and kill the innocent over the galaxy.

"Where to, sir?" CPU asked.

"Planet Abyss. To Chaos' palace." Alpha replied.

"Right away, sir." CPU said.

Alpha sat on the chair and asked, "What are the coordinates to Planet Abyss?"

"We will be arriving in 7 hours and 53 minutes." CPU replied.

Alpha relaxed on his chair and immediately fell asleep. He didn't think that he would dream of this again.

*Flashback*

Percy just finished his secret quest. He wanted to impress Athena so that she would allow him to marry her daughter. Percy was so excited. He couldn't wait to propose to Annabeth tonight but he was also nervous. To clear his mind, he walked to the beach to get some fresh air. He always spends his free time here, sometimes with Annabeth, since it just soothes him. He was walking along the shore when he saw Andrew making out with a wavy blond haired girl. He knew how that felt like so he turned and was about to walk away when he heard Andrew say, "Annabeth, when are you going to tell Percy?"

That got him to turn and he couldn't believe it. Annabeth was cheating on him with Andrew, his half-brother. Anger and sadness filled up inside him.

"Soon. I just have to find the right time and place to tell him. Maybe tonight I will be able to tell him." Annabeth said.

"You don't have to tell me." Percy said with tears in his eyes.

Annabeth turned and saw Percy. "P-Percy, you weren't suppose to be here until tonight." She said.

"I finished my quest early to get to see you but I guess you were too busy to miss me or even care about me." Percy said as tears were streaming down his face.

"Let me explain!" Annabeth cried.

"There's nothing to explain, Annabeth!" Percy cried, "I thought that you loved me but I guess I was wrong. I went to that stupid quest for nothing. I went through the twelve labors of Hercules for nothing! Athena approved of me and I got back here to see this!"

"Percy, ple-" but Annabeth got cut off by Percy.

Percy shook his head and said, " I was going to propose tonight but I guess that isn't going to happen," Percy said as he took out a silver ring with a diamond on top. On the ring was engraved, 'Seaweed Brain and Wise Girl Forever'. "I guess Hephaestus made this ring for nothing then."

Annabeth watched as Percy threw the ring on the ground. She didn't know that he was going to propose tonight. She felt guilty.

"Goodbye, Annabeth. Have a nice life without me." Percy said as he ran back to his cabin.

*Flashback end*

Alpha woke up when CPU announced, "We have finally arrived in Planet Abyss, sir."

Alpha just got up from his seat and got out of the ship.

"Sir, Lord Chaos has another mission in store for you." Alpha's lieutenant, Herman Melville said.

"So soon? I just came back from my mission." Alpha said coldly.

"But, sir. Lord Chaos said it was urgent. He needs to talk to you since you're back already." Herman said.

"Very well, lieutenant." Alpha said and walked into the palace.

The palace was well cleaned. Whenever Alpha turned corner to corner, the trainees would bow down to him and continue with whatever they were going to do. He reached Chaos' throne room and said, "My Lord, as you can see, my mission has been completed."

"Great job, Perseus." Chaos said.

Chaos calls Alpha by his real name whenever no one is around. Though, Alpha doesn't really enjoy being called 'Percy' or 'Perseus'.

"Thank you, my Lord. I have also heard from lieutenant Herman that you wanted to talk to me for my next mission." Alpha said as Chaos walked closer to him.

"Yes, well. As you already have heard, Gaea and the Titans are rising and the Gods are no match for them. So, I am sending you to Earth along with Omega and the troops." Chaos said.

"Even though I disagree to go back to Earth." Alpha sighed. "Very well, my Lord. Do the troops know about this?" Alpha asked.

"Yes, I told them earlier but I haven't told Omega. You have to tell her that since you both came from planet Earth." Chaos replied.

"Yes, my Lord. When do we leave?" Alpha asked.

"You'll leave at exactly 0800 hours." Chaos replied. Alpha nodded and walked out of the throne room.

Alpha made his way to his bedroom to see Omega looking out of the window. She was wearing her white gown. Alpha walked closer to her, wrapped his arms around her waist and laid his chin on her shoulder.

"I missed you." Omega whispered.

"I've missed you too." Alpha whispered back.

"I sense that there's a disturbance in you." Omega said casually.

"And how did you come up with that idea?" Alpha asked as Omega turned to face him.

Omega had sparkling blue eyes, a fair complexion and curly brunette hair. She pulled down Alpha's hood and mask and said, "Because I've known you for a very long time." She said as she traced Alpha's scars with her fingers.

Who is she really? I guess you're wondering. Her name is Alicia Beauregard Jackson. Yes, Silena Beauregard's sister and daughter of Aphrodite. Alicia has been missing for also 700 years along with Percy. She found out that Greek gods and goddesses were real and that she was the daughter of Aphrodite. Her scent wasn't that strong like the scent of the Big Three's children but it was able to attract monsters. Chaos found her and was able to recruit her but she was found right after Percy. They have been together for 500 years and 500 years ago, Percy also proposed to her.

*Flashback*

Alicia and Percy were on the balcony of Chaos' palace. They have been dating for 200 years now. Alicia noticed how nervous Percy looked that night.

"What's wrong, Percy?" Alicia asked. It was only Alicia and Chaos who knew his true identity.

"N-nothing's wrong." Percy stuttered.

"Percy, tell me. You stutter when you lie. I hate it when you lie to me but you do look cute when you lie." Alicia said and looked at Percy. He sighed.

"You do know we have been dating for over 200 years now and I want to spend the rest of my life with you." Percy said, pulled out a small velvet box and knelt down on one knee. Alicia gasped and covered her mouth. Alicia started crying. Not because of tears of pain but tears of joy.

"Will you marry me?" Percy asked and looked at Alicia's beautiful face.

"Yes!" Alicia said as Percy stood up, slipped the ring on her finger and they both kissed.

*Flashback end*

Percy was still heartbroken when Alicia came into his life but she fixed the pieces and he fell in love with her.

Alpha sighed and answered her question, "Lord Chaos sent us to a mission."

"And what mission would that be?" Omega asked.

"We will have to go back to Earth and help the Gods defeat Gaea and the other Titans." Alpha said and looked into Omega's beautiful eyes.

"And when will we leave?" Omega asked with a soft tone.

"We will leave at exactly 0800 hours." Alpha answered.

"Very well." Omega answered. She leaned in and kissed Alpha. Her hands were around his neck and his hands were on her waist. Alpha loves the feeling when Omega kisses him. He has never felt so in love before.
