A/N Hey guys! This is my first true attempt at a fanfic, so if i stumble along the way please excuse me. Just know that if you put this story in your library, it won't disappoint. This story will probably be with a bit darker Percy, focusing on guns as his main weapons.

Enjoy!

All I own is the plot.

Prologue

11:45 AM Afghanistan

Percy POV

Breath. Relax. Aim. Safety. Shoot. Percy repeated in his head as he shot the rifle, the bullet barreling towards the unlucky terrorist's chest. The bullet slammed into him, knocking him down in a thud. After the shot, the whole compound went on lockdown. Alarms blared, terrorists, scrambled around looking for their guns, trying to prepare for the soon to come slaughter.

Putting the rifle down, Percy managed a smirk.

"Bastards never saw it coming," Percy thought as he pulled out his M16 rifle. Rushing down the hill he had been sniping from, he engaged. The first terrorist he ran into didn't even get a chance to unholster his pistol, quickly getting two shots to the chest. Pulling a keycard off of the dead terrorist, Percy rushed into the first building he came across. The three terrorists inside pulled out their guns, but they were quickly dispatched by Percy's M9 pistol. Moving on, Percy had to get to cover due to the LMG being shot at him from a ramshackle tower. Pulling out a grenade, Percy lobbed it towards the tower, blowing up both the LMG and the terrorist.

"Okay, he told himself. One more building." As Percy busted open the door, he saw something he was not expecting to see. The leader of the terrorist group was a cyclops. A fucking cyclops. He left that life behind a LONG time ago. Luckily, he always carried a celestial bronze boot knife with him, just in case. The cyclops, noticing his entrance, pulled out an AK47.

"Since when do monsters use guns!?" The cyclops didn't respond, instead of starting to shoot at Percy. Realizing he was about to get shredded by bullets, Percy jumped behind a table, using it as cover. Realizing it would be near impossible to get close enough to the cyclops to stab him, he decided to do something risky. Percy rolled out of his cover while the cyclops was reloading, and threw the knife with all of his might. The knife hit its mark in the cyclops chest with a thunk. The cyclops dissolved into a golden dust. Percy was about to leave when he noticed the trophy the cyclops left. It was it's AK47. He picked up the gun and examined it. It seemed to be a normal rifle but he noticed something when he was clearing it. The bullets inside didn't appear to be normal. They were celestial bronze, Grinning, he felt the gun shrink and contort until it became a rifle shaped pendant on a bracelet.

"Hell yeah!" Percy exclaimed, realizing he now could kill both immortals and monsters.

"Are you done with your mission yet Jackson?" He heard over his comms.

"Yes, sir I'm ready for extraction," Percy replied, kicking up dust as he walked towards the gravel road.

"Alright, wait for a humvee by the road."

"Yes, sir." Percy could hear the low buzz of an engine coming down the twisty road towards him. He saw the yellow humvee with a turret mounted on top stop for him. Hopping in, he looked at who was inside. They all looked sick at the amount of death around the outpost. Percy smirked, newbies

"Back to base sir?" A tentative voice asked him from the driver's seat.

"That would be great… What's your name?"

"Private Smith sir." The young man replied.

"That would be great Private Smith," Percy responded. The engine roared back to life as the car took off, back the way they came. There was trash all in the road, causing bumps.

"Watch it Private, these damn terrorists will put bombs anywhere," Percy said cautiously,

"Sorry, Sir I'll tr-" He was cut off by a loud boom, and the humvee flipped over and over again. Percy felt a door being ripped off, and him being sucked out with it. He felt a searing pain in his right arm, and an enormous weight on it. An upside down humvee was the last thing Percy saw before blacking out from the pain.

When Percy woke up, he was in a blindingly white room. Looking around he took in the features of the room. He was on a thin cotton mattress, with curtains on his left and right. A blindingly bright lamp hung above smell of sterilizing liquid was in the air. Hopital Percy thought. Looking down at himself, he noticed his arms. His left arm was covered in scratches, and his shoulder ached. Looking at his right arm, "It isn't there. It isn't there. My arm is gone. It's gone. Percy's emotions went from confused to enraged. How could this happen to me? The once hero of olympus turned soldier, loses an arm!? That's not how the stories go! I'm the hero dammit! He started to struggle, but he was belted down. An orderly ran into the room, forcing him to calm down.

"Please, sir! You have to calm down, I know you're going through shock but you have to listen to me! Struggling will not help!" But Percy was not hearing it. He managed to get his left hand on his knife and cut himself loose. Looking around wildly, he found the exit. He started to run towards it, when suddenly a guard jumped in front of it. Not breaking his sprint, Percy barreled towards the man, when he suddenly jumped into a dive and drop kicked the poor fellow. He suddenly got tackled from behind and restrained.

"Your in big trouble Jackson. Big trouble."

A/N I hope everyone enjoyed the prologue! I know it was short, but I really had to get the plot down. Have a good day!
