Chapter 1

Third Person POV

Andronika, Queen of Sparta was tearing through the woods at speeds she thought she couldn't do, even with the blessing of her people.

Sparta was in flames, a distinctive plume of smoke was steadily rising behind as she ran for the sea. Strapped to her front over the top of her armour was a baby. And not just any baby. The baby was a demi-god son of Poseidon. Her and her husband were going to raise the child in honour of the gods and Sparta, for him to be the perfect prince, humble and kind to everyone and merciless to his true enemies.

Andronika stumbled onto the sand and clutched Sparta's final legacy close to her chest as she waded into the water. She gently placed her son, Perseus or as she had taken to calling him, Percy, on the water and prayed to her lover. Please Poseidon, take our son and raise him until he can look after himself. The tide took the child out to sea as Theban soldiers burst onto the beach and forced Andronika to her knees. One soldier who looked to be in charge crouched down to be at her level.

He tenderly brushed back some hair from her face and leant forward to be next to her ear. "You know sweetheart; I might just let you grace my bed tonight." He whispered and planted a tender kiss on her cheek and pulled away.

Andronika glared long and hard at the man.

She would do anything do her Percy was safe.

1066, Calais, France

Percy POV

I was a literal arc of destruction as I decimated the enemy lines. Dad had told me it was crucial that England and the surrounding countries stayed under their own rule until the next millennium so here I was, destroying the Norman forces.

August, 1588, England Coastline

"Sir, the ships are coming in." Leroy Smitherson, a loyal soldier of mine said, coming to stand next to me. I stared out of the cliff, and I could just make out the ships.

"It seems I ought to cause some rough seas then does it not?" I smirked. Leroy was the only one that knew of my heritage and the true consequences of me losing my anger. Being born of Sparta meant I inherited the curse. Ο Σπαρτιάτης οργή του αίματος or the Spartan Blood Rage, was a blessing the Ares placed upon my people long ago when the city was first founded. Being the last Spartan around Ares had made me his champion in honour of his people, hence making me partially immortal, like Artemis's hunters, only able to fall in battle

I felt a now comforting tug in my gut as I forced the sea into becoming choppy as the ships smashed against the rocks. A storm was forming above our heads, rain pelting down on us as the fleet was narrowed down to a few ships. Our fire ships went out and the Armada went down to the depths. Cheers and shouts rang from my troops and I remained stoic. This was only a battle in a war.

Germany, 30 miles behind Hydra lines, 1941

Upon orders of my father, I was shadowing Captain America on his messed up mission of saving roughly 400 men from a Hydra base in a hope that his friend, James Barnes was there.

He jumped out of Stark's plane and landed somewhat hap-hazardly on the ground, thankfully in one piece.

I crept up to him.

"So what's the plan Cap?" I smirked

He jumped and spun around, shield ready to attack me.

"Who are you?!" He asked

"Percy…Jackson." I hesitated and made up a surname. Jackson… I can work with that.

"Nice to see an American I suppose that still has the accent."

I laughed. "Plan?"

"Save men, piss off Hydra."

I blinked. "You know Cap," I broke into a grin. "I might just be able to get along with you."

We Shook hands.

"And I you, Jackson."

We stormed their defences and infiltrated their building. I mean seriously, we were in the facility within 5 minutes of turning up. How weak are their defences like sheesh!? We headed to the cells and I heard a girl scream. We spun around, it was a girl, no older than about 7, trashing against some soldiers as they tore at her clothes. My blood boiled.

"Save the soldiers, Captain, I've got some demons to kill." He nodded at me and ran off, Killing at least three men with a single throw of his shield.

Time to cause havoc, I thought bitterly before I charged the men.

One looked and shot at me but I just tilted my body to avoid them. I slammed my fist into his face and span and knocked out his mate with a roundhouse kick to the face. The girl was crawling away, her fiery red hair looked almost like it was glowing in the light. Her clothes were torn and left very little to imagination. I tore off my cloak and walked towards her. She shimmied further into the wall.

"Who-who ar-re you?" She whispered, terrified. I stopped a couple metres in front of her and pulled off my mask, revealing my sea green eyes, tanned skin and messy black hair.

"My name's Percy Jackson, what about you?" I asked kindly, motioning her to come to me.

"N..Natash..a….Natasha Romanova or…or Romanoff." She scuttles towards me.

I helped her stand up and wrapped my cloak around her, transforming it into a Chiton to retain her modesty, tying it off behind her neck.

She flung herself at me, her green eyes damp with tears.

"Thank you, thank you, thank you." She repeated whispered into my ear.

"Anything for you Naty." I joked; I don't know why, but I had an extremely overprotective feeling surge through me. "Climb on my back and I can get you out of here."

With assassin's grace she swang around and wrapped her young legs tightly around my torso.

I rose to my feet and told her to hang on tight.

I broke into a run, Justice, my sword I used when I was dealing with mortals, in my hand. I weaved through passages and corridors towards the sound of battle. I found Captain America in a standoff with Smidt.

"So why are you running?" I heard him say as the scientist and Smidt disappeared into the elevator.

"CAPTAIN!" I shouted at him. "YOU HAVE TO GO NOW!"

The explosions were happening right below us and soon they start rising up.

"NOT WITHOUT YOU!"

I sighed. I prayed to Aunt Lady Hestia.

Lady Hestia please hear this little ancient demi-god's prayer. Please make some kind of bridge with the fire below so we can get out. I Know you're not supposed to mess with mortal affairs but since I'm not mortal this can work right?

I heard a chuckle in reply and the flames were raised into a path from the side we were on to the side where the stairs were. Barnes and the captain yelled in surprise.

"TRUST ME CAPTAIN THIS WILL WORK JUST RUN ACROSS IT!"

"ARE YOU TRYING TO KILL ME PERCY JACKSON?"

I rolled my eyes. "YES NOW GO!"

I saw him roll his eyes as he tentatively took a step forward, when it didn't burn him his eyes widened.

"ANY TIME TODAY CAPTAIN." I sarcastically called and he grabbed Barnes and ran across. I twisted my head so I could see Natasha.

"Do you trust me?" I asked. She squeezed me tighter and nodded into my shoulder. I ran to the bridge and across it

"We made it!" I whispered and her vice like grip lessened.

~~~Time Skip~~~

We were on the final stretch of our journey, The Captain who's name I learnt was Steve Rodgers, James 'Bucky' Barnes, Natasha and I were laughing at the front of the 400 men we saved. I turned to the two guys as the division became in sight.

"I'm sorry but this is as far as we can go." I said sadly as I shifted Natasha on my shoulders.

"But you're a hero, Perce, you need repaying!" Steve exclaimed.

I shook my head. "Meeting you guys is all the payment I need. One day Steve, you'll understand."

I embraced the pair in a hug and Natasha placed a sloppy kiss on both of their cheeks and high fived them. We had grown close and I felt bad to leave but it was for the best.

I looked after Natasha for ten years teaching her combat, knives, guns and daggers. As it turned out, Hydra had given her this serum meaning she would age much slower than the average mortal. As far as Apollo and I could figure out, she would age normally until she was 24 and then the serum would kick in.

When she was 17 she joined shield and quickly built an incredible reputation for herself, becoming known as the Black Widow. She was an assassin of Justice, killing off anyone the world would be better without.

It was 2006 when my Dad Iris-messaged me.

There was a list of things.

Zeus knew I existed

His master bolt was missing

Zeus thought I took it

I needed to go to Camp Half-blood

I had to be a 12-year-old

It was going to suck.

Lady Tyche? Please may I have the best you have to offer?

Xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

I stumbled through Camp borders and I could feel the stares on my back stumbled to the Big house where I saw Chiron and Dionysus.

"I'm here Chiron." I mutter collapsing on the nearest seat.

"It's been a long time Percy." Chiron smiled. When I was only seven I met Chiron and he trained me non-stop for twenty years. Somehow, by absolute miracle, he had even managed to make me be acceptable at archery.

But still. I was stuck in a camp with a bunch of amateurs for at least a few years.

I sighed.

This was going to be a long few years.
