(Sparta, 500 B.C.)

A young woman in her late twenties, wearing nothing but a silky chiton, ran through the woods, carrying a small blue bundle in her arms.

She could hear the enraged shouts behind her grow louder as her pursuers got closer. She gave it all she had, for the sake of the little blue bundle in her arms. She ran for the sake of her newborn son.

She ran towards the shores, towards the domain of her lover. Then he could protect her and her child.

But when she appeared on the shores, it was too late. A zip and an arrow sailed through the air, avoiding all branches and obstacles, miraculously avoiding the little birds, and landed right on target.

The young woman had no time to even register her pain as the arrow passed clean through her skull.

The blue bundle slipped out of her arms and as it fell, the newborn son fell into the shallow waters of the Aegean. But no sooner had the men closed in on the boy, the tides rose, sweeping the baby away from the shores.

The men clothed in black leather grunted and groaned. They had failed their mission. They failed to kill the son of Poseidon.

(460 B.C.)

The baby boy, now grown up, swung his swords hard against the wooden dummy, taking it's head clean off.

A bearded centaur watched from the sidelines of the training arena, smirking as the wooden dummy was destroyed. "And how has the wooden dummy offended the great Perseus?"

The man (Perseus), smiled, hearing his mentor's voice. "Chiron! You're back.". Perseus sheathed his swords behind his back.

Chiron smiled. "I see you're dual wielding now."

"I perfected the three sixty defines you've told me. It works."

Chiron smiled. That was the most precious move he could ever teach. Being a centaur, he couldn't do it himself, but he'd seen Perseus use it. It was as the name suggested. A form of combat wherein a warrior could engage enemies even if he was surrounded. That sometimes meant taking on several dozen men at once.

Most regular humans could never achieve such a feat, but Perseus wasn't a regular human. He was the son of Poseidon himself and the power of the oceans flowed through his veins, making him more powerful than anyone could have ever imagined.

He wasn't any regular demigod either. A child of the big three, trained by Chiron in his early years and later on he was trained by Athena in the arts of combat and military strategies. He soared ahead of normal capabilities and his intellect rivalled Athena's own.

Basically, you do not want to face him in battle. A ruthless warrior, who learned to fight dirty if the need arose. He learned to mind his surroundings and to use it to his advantages.

His used his powers given by his father. This, he had to learn on his own, since Poseidon rarely visited. He honed it to the point where he could use it as a weapon or for healing.

With the power over water came an ability most demigods already have. The power to control the mist. He learned to use it to create illusions and to distract opponents he knew he couldn't beat.

When Zeus learned of Perseus, he first wanted to strike him down. But he realised two things. One, Poseidon would be enraged, and frankly, Zeus didn't need that. Contrary to popular belief, Zeus was only slightly more powerful than his brother. Secondly, he needed someone like Perseus. Someone who could interfere anywhere and anytime, without breaking the ancient laws and upsetting the fates. So when Perseus turned nineteen, he made him half immortal, just like Artemis's hunters, but gave him a little more power.

The one odd thing was that he belonged to no city-state. He never really learned his mother's name or where he was from. All he knew was that as a newborn, he was washed ashore just a few hundred miles from the foothills of Mt. Olympus.

There, he was found by Chiron, the trainer of heroes, and you know how that story goes.

He didn't step foot in most cities unless it was for an assignment. He did have a small addiction to having gods owe him. He would do assignments for some gods, especially Hades, and when the time would come, he could call on them for any help.

Most favours were borderline insane, going from assassinations to sabotaging weapons of gods. At one point, Hermes used him as a vessel, his essence entering his body so that the god could watch as Perseus spied on Artemis and her hunters while they bathed. Needless to say, Hermes respected him from then on. Only the maddest of men would dare try something like that.

Perseus suspected Hermes had something to do with that though. He was never particularly good at being stealthy, but from then on, he was the best of the best.

Now, Perseus owned a small palace near the foothills of Mt. Olympus, complete with a training yard and a way towards the lake. An archery range was there, but it was useless. None of his shots hit the target. Perseus started to fear, thinking that maybe he wasn't as stealthy as he thought when he spied on the goddess of hunters.

But he was never confronted about it and Perseus didn't bother worrying himself much for that.

Most of his fun included screwing around with Apollo or performing some rather stupid activities with Hermes.

But with friends came a list of unfriendliness. Ares, for starters, hated his guts. The war god butted heads with him more times than he could count. Dionysus wasn't much of an enemy but more of a frenemy. He wasn't sure what he felt towards Aphrodite and Hercules was his absolute worst enemy. The son of Zeus was far too arrogant for his taste, and also a bit of a snob.

Speaking of enemies, one had just appeared in front of him. Perseus sighed as the war god began to pompously announce the fact that Zeus was summoning him.

Sighing, Perseus dropped wiped a bead of sweat from his forehead and walked inside his quarters, preparing to meet the big man up the hill. Hopefully this time he wouldn't have to shadow some demigod on his mission.

(Hades' Palace, The Underworld, 2017 A.D.)

Perseus stood casually in front of the Lord of the Dead and his wife, watching as Persephone glowered at her husband.

Hades looked a little nervous. "They aren't new! I swear!"

Persephone didn't look convinced. "Whatever. I'm off."

In a flash of gold, she disappeared, leaving a relieved King of the Underworld. "Phew. She's gone. Now Perseus, do you remember the task?"

Perseus nodded. "Yeah. Get the kids here and keep their father's identity a secret ... but Persephone knows, so how can it be a secret if three people already-" He stopped, noticing the deadpan stare he was getting from the god.

"Fine. I'll get them. But I want that credit card you told me about. And that phone."

Hades grumbled. "Kids these days."

Perseus frowned. "Hey! I resent that."

Hades rolled his eyes. "Fine. Go."

With a snap of his fingers, Hades teleported Perseus out of the place.

Please review and tell me how it is. I know this plot has been done a gazillion times, but just give it a shot. I'm trying to make this Percy less dark, and his character more like the books, except that he's not innocent. (spying on the hunters, etc.)

Also. Pairing please?

Annabeth or Thalia or anybody. Literally anyone.

But no Nico or Apollo, etc. Please don't make Percy gay.

I've got nothing against gay people, but I feel uncomfortable writing about gay stuff. Trust me, I tried.
