Hello readers! I've been reading a lot of crossover works and I love love love the idea of Percy emerging from Tartarus in a different dimension. This is my take on Fairy Tail. Percy emerges after 24 years in the Pit to Earthland. Anna Heartfilia and Zeref use the Eclipse portal to initiate the 400 year plan and as the dragon slayers are sent forward in time. Percy gets launched to Tenrou Island where he meets Mavis, Yuri, Precht, and Warrod. Due to his half divinity and high ethernano concentration, he doesn't age past 17 and becomes a founding member of Fairy Tail. He is dubbed "The Fairy God-Slayer" and eventually joins the Fairy Tail plot as they return from Tenrou Island after the 7 years.

3rd Person POV

Alone for the last 24 years in the Pit. For those that are familiar with the Greek equivalent of "Super Hell", it should have been impossible. He should've died on impact of falling. He should've died by the poisonous atmosphere. He should've died at the hands of the monsters he had been slaying since he was 12.

He should've died with his beloved. He should've died with Annabeth.

But for the "old" demigod, doing the impossible had become as normal for him as one puts on a pair of socks. For Percy Jackson, the impossible was just a word people used to make themselves feel better about their failure.

And fail, he could not.

Flashback

He was gripping onto the ledge of Tartarus with Annabeth in his other hand, praying to every divine being he could think of that he would have the strength to pull the two of them out. Prayers that fell on deaf ears, as most did in his experience with gods.

He didn't fault them for that. Well, he did, but he had grown accustomed to it and it was for that reason that he stopped with the semantics long ago. He could only rely on himself and his friends.

Annabeth started to slip from his grasp and he knew that he too couldn't last much longer. He vaguely heard the desperate pleas of his love to let her go and save himself, but she too should have known that those were falling on deaf ears.

He took one last look back at the sweat caked face of his love and he made his decision. "Nico!" He yelled to his brother in all but blood. "The Doors of Death! We'll see you on the other side!" He called and his cousins face turned 3 shades whiter, which would have been comical in literally any other situation.

"No! Perce just hold on!" Nico begged him, but he just shook his head. "Complete the mission on your end!" He said and looked to Annabeth one more time, studying every last detail of her face. "We'll handle it on our end!"

Before either party could say another word, he pulled Annabeth to him with all his strength and let go of the ledge. The cries of his friends couldn't be heard over the winds as he hugged Annabeth for all he was worth and they plummeted into the Pit.

He did not pay attention to how long they were falling. All he could focus on was the love of his life in his arms as both their bodies were racked with sobs and guilt.

Despite the wind, he heard her voice as clear as day, "why?" He pulled from her embrace and looked at her with a sad but accepting smile. "We promised we'd be together no matter what, Wise Girl," he told her and she cried again.

The next "days" of falling, the two of them recounted their time together and their adventures. They laughed on occasion and cried on others as they relished the brief peace they had in the fall.

"Percy," she whispered and he looked in her eyes. "Promise me you will move on. Promise me you will never forget how much I love you and how glad I am we had our time together," she told him as her lip quivered.

"W-What are you talking about, Wise Girl?" He murmured. "They need you, Seaweed Brain. I-I'm not going to survive the fall. I know it. I don't know if it's the despair of the Pit or if it's the Fates whispering in my ear, but I'm not going to make it," she told him and he began to panic.

"NO! We're in this together! I'm right here!" He pleaded with her and she gave him a watery smile as she pulled him close. The blood red clouds of the Pit came into view finally and she whispered in his ear, "I will always love you, Seaweed Brain. I am proud to have had you and I will always be yours. I love you. Remember your promise."

With the last ounces of her strength, she pushed him away from her. His trajectory to one of the 5 rivers below and hers to the glass shore. "ANNABETH!" He roared as he crashed beneath the river of misery and blacked out.

In his unconscious state, he heard her call to him. "I love you, Seaweed Brain. Wake up," her ethereal voice beconed to him. "Annabeth," he tried to reach her. "They're coming. You need to wake up."

"No! I won't leave you!" He desperately cried. "Remember your promise. WAKE UP!"

Percy jolted awake, somehow on the shore of the river and incredibly sore. He didn't move as he gathered his wits about what had occurred.

Eventually, he could move and he sat up to look around. There was no sign of her. Percy sat on the shore and openly cried for all he had lost. In his numbed sniffles, he heard her final words one last time, "remember your promise."

Sorrow and grief turned to anger and rage as he began to move. He had a mission to complete.

End Flashback

I was hard to believe to the demigod that he had been down there for 24 years. Granted, not all of it was alone. Surprisingly, he found a friend in an old enemy: Medusa of all people.

Sure they tried to kill each other a handful of times, but the two of them swallowed their pride and worked together to ensure their survival. Mutually assured survival blossomed into friendship after a decade and Percy was certain he wouldn't have survived the Pit without her.

But she was gone now too. Killed in a skirmish and reforming Zeus knows where in the Pit. He was alone again.

Alone, so he trained. He trained and if he wasn't the strongest demigod in the age and perhaps history before the Pit, he certainly was after it.

His control over water elevated to God-level, manipulating both blood and poison, and even altering the pH of the water to make it corrosive. His sensory ability to track and scout with the water allowed him to have eyes and ears for a mile around him.

He could even disassemble his being into water particles and travel through as vapor for extreme stealth which was crucial to his lone survival.

His father's domain over earthquakes blossomed too. He could channel it through the ground and exhibited Geokinesis, allowing for offensive, defensive, and sensory tactics through the vibrations in the ground. He could even channel it into his CQC and through the air. His punches had never known such power.

He had minor aerokinesis though nowhere near the level as his friend Jason, but enough to speed his movements and control his descent when falling. Similar abilities with lightning, but Thalia would beat him everyday of the week and twice on Sundays.

He was truly a force to be reckoned with in the Pit, but that didn't stop the monsters from attacking. His ability with Anaklusmos, while always deadly, had taken the primal nature of a beast fighting for survival. It was sporadic and unpredictable like the sea, but just as deadly as before.

For 24 years he traversed the Pit and it was during the 24th year that he would finally escape. He made it to the Doors of Death and managed to pry them open. Though he did not know that he wouldn't emerge in his dimension.

Earthland X377

Anna Heartfilia and Zeref we're preparing to send the dragon slayers forward in time by 400 years to ensure the survival of both them, and the rest of life as they knew it.

"It is time," Zeref told Anna and she nodded. The 12 Celestial Keys for the 12 Zodiac Spirits were used to open the Eclipse Portal. "Our fate is in their hands now," Anna said and jumped through the portal after the five young dragon slayers. Sting, Rogue, Gajeel, Wendy, and Zeref's younger brother Natsu.

Just as the portal was closing. A gold energy flew out of the door and vanished into the sky. Zeref watched the light with narrowed eyes, though he could not be certain what it was. His only thoughts were on his brother and the hope he held for the future.

A future to be free of Aconologia.

Tenrou Island X377

The golden light that fled the portal at the last second crashed into the heart of the forest on Tenrou Island, leaving a crater in its wake just as the newly formed group of Yuri, Precht, Warrod, and Mavis were about to leave.

Upon hearing and seeing the crash, the four newly found friends dashed to go investigate. They never expected to see the smoking body of a young man, maybe 17 years of age in its epicenter.

They approached cautiously and the figure began to move. Every one of them, on edge except for Mavis. Her gaze held more curiosity than weariness and the figure sat up.

The sea green eyes that pulsed with power locked onto Mavis' own. "Where am I?" He croaked and the group narrowed their eyes at the windswept raven haired teenager.

Mavis walked forward, to the dismay of her friends and stuck a hand out to the boy.

"You're on Tenrou Island. I'm Mavis," she said cheerfully and the boy groaned.

He tentatively took her hand and offered a small smile that looked more like a grimace.

"I'm Perseus Jackson, but you can call me 'Percy'. I don't think I'm in my dimension anymore," Percy said and they groups eyes widened.

AN: I think I'm gonna have fun with this for shits and gigs but lemme know what you think! Again I really love the idea of emerging from Tartarus in another dimension and I'll likely do other crossovers. Namely RWBY, Young Justice, and One Piece! Please lemme know your thoughts!
