Back and still different

Summary:

What would happen if Percy Jackson and Harry Potter were the same person?

I've read very few of these, so I wanted to make one myself (⁄ ⁄•⁄ω⁄•⁄ ⁄)⁄.

Summary:

Harry Potter dies from his abusive uncle, after being betrayed by whom he considered a grandfather.

Percy Jackson commits suicide after all the Greek and Roman demigods die from the battle against Gaia and discovering a secret of the Gods.

Both are a soul split in half that unite when dying and becomes the master of death.

They have been in the dark for a long time, they began to forget things, they decide to come back to life in another universe where both worlds are.

This gives them more adventures and fatigue.

 

As you know from the warnings, I don't own the Percy Jackson and Harry Potter characters, I just make them suffer.

Percy/Harry out of character and many more things.

It's also very out of canon, but not that much.

Chapter 1: Chapter 1

Chapter Text

After his fifth year at Hogwarts, a deeply depressed Harry was forced to return to the Dursleys—the people who had abused him since childhood.

 

This time, it was worse.

 

They beat him every single day, stopping only when he lost consciousness.

 

The only thing Harry could think about was betrayal.

About how his friends had abandoned him.

Flashback

 

Harry stared down at the parchment trembling in his hands.

 

His inheritance test.

 

Gringotts had contacted him shortly after Sirius’s death.

 

“Mr. Potter, we assure you that everything stated on this document is accurate,” his vault manager said calmly.

 

Tears streamed down Harry’s face as he continued to read, his hands shaking violently.

 

“I want everything that was stolen from me returned—with interest,” Harry said, his voice breaking.

“And in return, I’ll give Gringotts thirty percent of the recovered assets.”

 

The goblin smiled, clearly pleased, and nodded.

 

He guided Harry to a sofa, encouraging him to rest.

End of flashback

 

Malnourished.

Abused.

Depressed.

Betrayed.

Abandoned.

 

That was all Harry was now.

 

He had already reached his breaking point—but everything shattered completely the day Vernon came home furious from work.

 

And, as always, Harry became his outlet.

 

“Get over here, boy!” Vernon snarled, gripping Harry’s wrist painfully and dragging him toward the basement.

 

“P-please—u-uncle Vernon—” Harry begged, trying to pull away.

 

“SHUT UP!”

 

Vernon shoved him down the stairs.

 

Harry groaned as he struggled to sit up, clutching his right side.

 

That hurt.

 

Vernon grabbed him by the hair and slammed his head into the floor again and again.

 

The pain was unbearable.

 

Then his vision began to blur.

 

Darkness swallowed everything.

POV: Harry

 

There was nothing.

 

No sound.

No light.

No warmth.

 

Is this what death feels like?

 

Empty.

 

“You have nothing to fear, my master,” a voice said.

 

Who are you? I asked silently.

 

“I have many names,” the voice replied smoothly, “but you may call me whatever you wish.”

 

“Are… are you Death?”

 

“You could say that. I am Thanatos—the God of Death.”

 

For some reason, his goofy smile eased my fear.

 

“What do you want from me?”

 

Thanatos laughed.

 

“So blunt,” he said fondly.

“You are Harry Potter… or rather—Percy Jackson.”

 

I frowned.

 

“What do you mean?”

 

He sighed.

 

“There are countless universes—multiverses, if you prefer. Your soul exists in more than one form. But yours is… unique.”

 

My eyes widened.

 

“Your soul was split in two. One half remained here. The other was born into another universe. When both halves die at the same time, they reunite.”

 

My heart skipped.

 

Then I remembered something.

 

“What is Dumbledore doing right now?”

 

I wanted the truth.

All of it.

 

“Come closer.”

 

He raised his hand, revealing a glowing sphere.

 

Inside it—

Narrator POV

 

Dumbledore paced back and forth in his office until the door opened.

 

“Molly, my dear,” he said with relief.

 

“Everything is taken care of,” Molly replied proudly.

“I gave Ronald and Hermione obedience potions, and Ginny knows to lace Neville’s meals with Amortentia from now on.”

 

Dumbledore handed her several vials.

 

“Excellent. Neville will be recognized as the new Chosen One. With these potions, he’ll be perfectly compliant.”

Outside the sphere

 

“That bastard…” I hissed, clenching my fists.

“He used my friends like chess pieces.”

 

“Do not worry,” Thanatos said calmly.

“That world will collapse in five years because of his choices.”

 

I smiled faintly.

 

 

---

 

POV: Harry

 

“Now,” Thanatos said, “I will take you to Perseus Jackson—so the two halves may reunite.”

 

The world dissolved.

 

 

---

 

I found myself facing a boy with messy black hair and sea-green eyes.

 

He looked about fourteen.

 

Scarred.

Wounded.

Wearing a torn orange Camp Half-Blood shirt.

 

Nervous.

 

“Hi,” he said softly.

“I’m Percy Jackson.”

Another Universe — Weeks Earlier

 

Percy Jackson was the only demigod left alive after the war against Gaea.

 

Everyone else was dead.

 

Nico.

Jason.

Thalia.

Annabeth.

All of them.

 

He woke up in the infirmary.

 

“Everything hurts,” he muttered.

 

When the memories hit him, he broke.

 

Chiron held him as he cried.

 

“They’re really gone, aren’t they?” Percy whispered.

 

Chiron said nothing.

 

That was answer enough.

 

 

---

 

The gods offered Percy a wish.

 

“I want to be with them,” Percy said, smiling sadly.

 

“With my friends. In Elysium.”

 

They panicked.

 

Tried to keep him.

 

Promised to do better.

 

Eventually, Percy agreed to stay.

 

But the grief never left.

 

 

---

 

Weeks later, Percy learned the truth.

 

He was Perseus.

 

A child created by Poseidon, Zeus, and Hades.

 

If they found out he knew, they would force immortality on him.

 

So Percy chose his own ending.

 

He pressed Riptide to his throat.

 

And let go.

 

 

---

 

He opened his eyes to Thanatos.

 

“Will you take me to my friends?” Percy asked hopefully.

 

“No,” Thanatos said gently.

“There is something you must see.”

 

Then—

 

He brought another boy forward.

 

Bloodied.

Broken.

 

“Hi,” Percy said.

“I’m Percy Jackson.”

 

“I’m Harry Potter.”

 

They looked at each other.

 

And understood.

 

Thanatos took their hands.

 

Light exploded.

 

Only one remained.

 

 

---

 

“What will you do now, my master?” Thanatos asked.

 

“I don’t know,” the boy said softly.

“I think I’ll stay here.”

 

Thanatos smiled.

 

“Of course.”
