Percy walked out of the shadows in his bedroom and yawned. He needed to get some rest before tomorrow. Poseidon would be coming early, but first...

"Persephone!" Percy yelled.

After a few seconds later the goddess poofed in.

"Yes?" She asked.

To Percy's surprise, she didn't try anything funny.

"I need some new weapons. The current ones I have are breaking." Percy said, pulling out his broken gun and his throwing knives. His throwing knives were small and near breaking from three years of constant use and sharpening.

"And why can't you do this." Persephone asked.

"Because I have no experience in making weapons and I can't just walk into a gun store and demand a dangerous weapon."

Persephone rolled her eyes but sighed in defeat, which made Percy smile.

"Good, here is the list of weapons I will need." He said, handing over a sheet of paper from his pocket.

Persephone stared at the list before raising an eyebrow at Percy.

"How do you know about all these weapons. And why do you need most of these. I thought you just needed guns and throwing knives."

"I know, but this," Percy said, pointing to an item on the list. "Is for long range assassin ops. A bow and arrow can do everything. Mortal weapons are useful too."

"And the rubber bullet ammunition along with amour piercing rounds?"

"A guys gotta practice somehow, and I can't use the live rounds because I need those for missions. Some monsters have tough hides." Explained Percy.

Persephone rolled her eyes and sighed.

"Fine I'll do it. But you owe me."

"No I don't. This is me forgiving you for trying to seduce me"

Persephone narrowed her eyes but said nothing as she poofed away. Percy went to his room and changed into his sleep wear. Waking up on his bed was Oreo with a face that said 'Where have you been all day'

"I'd rather not talk about it bro."

The hell hound smirked before going back to sleep. After about a half hour, three duffle bags came from the shadows and landed next to Percy bed with a solid thump. Percy silently thanked Persephone and walked over to the bags. Inside the first two bags was a ton of ammunition for Percy's guns since he relied on his guns often in a fight. He carefully took each box out and separated them into their own category of amor piercing and rubber rounds. In the second bag was what Percy was waiting for. It held two black forty caliber PT 101 handguns, and something way more dangerous. At the bottom of the bag was a L115a3 British bolt action sniper rifle. It fired a 8.59 caliber bullet and a range of 1100 meters plus. It held a five bullet magazine and fired a bullet at 936 meters per second. And to be honest, it was as sexy looking as it was deadly.

Percy shouldered the rifle and looked down the sights. He loved the weight of it and the power he felt holding it. Percy put his weapons into his bag and went over to the bullets. He took his time and loaded each bullet into a magazine. He put a magazine of amour piercing rounds into each of his guns before returning them to his book bag. He then placed the rest of the ammo into the front pouch, where he kept all ammunition. He then climbed into bed next to Oreo and fell asleep, weary from the events of the day.

LINE BREAK

Percy knew he was going to hate this last year of training. Poseidon came and got him from hades that morning like he said he would, and transported him to Atlantis where he met his wife and son, Amphitrite and Triton. At first Amphitrite thought Percy was another "sea spawn", but after much convincing, she finally calmed down. They all chatted and talked about Percy's training while eating breakfast. Amphitrite commented on Percy's choice of clothing and he just rolled his eyes. That was the good part of the day. When noon came, Poseidon told Percy it was time to train. The god went and grabbed a large sack and threw it over his shoulder before kissing his wife and hugging his son.

Then they began their walk to the training grounds. Percy was moving much slower than Poseidon because the god only blessed him with the power to see, hear, and breath in water.

Apparently before Percy could control water he needed to be "comfortable in water just in case the blessing wears off". Whatever the hell that meant. Anyway, after about twenty minutes of walking, they came to a giant hole in the sea floor.

"This hole goes three miles down and is three miles wide in all directions. The pressure would kill a normal person, but this is were you will train." Said Poseidon.

Percy raised his eyebrows and looked at the sea god.

"I'm sorry, I don't think I heard you right. Are you telling me I'm going to be training in high density water for the next year and three months? And that it might kill me from the pressure?

Poseidon looked thoughtful and nodding slowly.

"Yep, sounds about right."

Percy shook his head before sighing.

"Okay, so how do we get down there. Is there like, a staircase or something?"

Poseidon laughed before planting a firm kick into Percy's ass.

Percy cursed as he went twenty feet out from the edge.

He began slowly started floating down and Poseidon followed shortly after.

"You know, you could have just told me to jump." Said Percy, glaring at the sea god.

Poseidon just shrugged and a silence fell over the two.

"You know I met a son of Zeus yesterday named Orion. Kinda weird how Zeus would name his kid after one of your sons." Percy stated

Again Poseidon shrugged and it made it apparent he had something on his mind.

"Is something wrong Poseidon?"

"Hm?" The god hummed, looking at Percy as if seeing him for the first time.

"Is there something on your mind?"

Poseidon shook his head.

"It isn't something you would understand."

"Try me."

The sea god looked shocked before sighing.

"Amphitrite has become increasingly agitated. She said I'm not giving her enough attention because I'm too busy 'screwing' mortal women." Poseidon sighed again. "I... She said she wanted a divorce. She wants to find a man that would treat her with respect. Not someone who would just use her to get an heir."

Percy was mind blown. It sounded like Poseidon was having family issues; and yet here he was, training him.

"So, um... Don't you want be home instead of here?" Asked Percy

Poseidon shook his head.

"It's too late, she is already planning on leaving. And she's taking Triton with her. So not only will I be left without a wife, but I will also have no one to take care of my throne when I'm gone."

Percy felt really bad for the guy. No wonder Amphitrite seemed livid when Percy came into their home.

"So what are you going to do now?"

Poseidon shrugged before cracking a smile.

"But we shall not worry about that. We are going to spend the next year and three months in this hole, and then you will have completed your training, and we will give you our full blessing."

Percy nodded and they fell into a comfortable silence, still floating to the bottom.

After about ten minutes, Percy began to breath really heavy. The pressure he was feeling was pushing against his chest so hard, he felt like he couldn't breath. Next his ears popped like cannons.

As they got closer to the sea floor, blood started coming out of his nose. When the finally reached the bottom, Percy tried to stand, but the pressure kept him on his hands and knees. He lifted his head and looked around. It was dark, but the power of Hades allowed him to see. It seemed like a regular training camp that you would see on land. It had a barracks, a sword arena, and a mess hall. The mess hall was in a giant bubble which had no water so that Percy's food didn't get wet.

"First order of business, we need you to get use to the pressure down here, so I want you to give me a hundred push-ups. Starting now." Poseidon said, not effected at all by the pressure.

Percy sighed and got into a push-up position. This was going to suck.

LINE BREAK

Percy was dead tired. He climbed into the bed inside the barracks covered in sweat. He still could barely stand in the water, so he crawled all the way to his bed. He skipped dinner entirely because he was too tired to eat. When Percy finally got under the covers, he was knocked out before his head hit the pillow, sending him to the land of Morpheus.

TIME SKIP: NINE MONTHS

"That's it Percy, your really getting the hang of this." Said Poseidon as Percy used the water around him to make whip.

Poseidon was truly impressed by the demigod. Four months after they got down in the hole, Percy was somewhat to the pressure and running three miles, only stopping every once in a while. Two months later he was running the entire thing and slicing dummy heads like it was second nature, which it kind of was. Two months ago Poseidon had given Percy his blessing for water and the young teen excelled in all forms of water usage. He could use the water to make weapons and shields that would help him a fight. Now he only had six months left until the returned him to the surface. His fourteenth birthday was only half that time.

Percy used the water whip to hit a dummy twenty feet away. The water went straight the metal head of the dummy, and it came clean off.

Percy gasped for air as he pushed his body to the limits. He had already been using his powers for over five hours nonstop. It was sapping his strength like crazy and he was close to passing out.

"Let's take a break." Suggested Poseidon.

Percy nodded and dropped to the ground. He was covered in sweat and had discarded his shirt long ago, showing off his hard earned muscle and various scars he got.

"How about you go for a light jog to cool you down." Said Poseidon.

Percy said nothing as he stood up and began his long jog around the hole.

TIME SKIP: SIX MONTHS

A fourteen year old Percy sprinted to a finish next to a certain sea god.

"Well done Percy, you have succeeded in completing all four years of training by the gods. We must return to the surface at once to celebrate." Praised Poseidon. Percy smiled his rare smile, not even tired from his three mile sprint.

Using their water powers, they shot out of the hole at neck breaking speed. To Percy, the feeling of the water up there was like walking through air. The high pressure water in the hole made the water out of it feel like nothing. They walked quickly to Atlantis where everyone bowed to Poseidon and smiled at Percy. He even got flirtatious winks from a few mermaids. When the made it to Poseidon's palace, he walked through the door to find it empty except for his servants. Amphitrite and Triton were gone just like they said.

They continued to walk until they made it to the throne room. They walked in and was greeted by an awesome sight. Standing in the throne room was Apollo, Hades, and Persephone. They wore colorful Party hats, which Hades didn't look to happy about, and streamers along with balloons decorated the walls.

"Surprise!" They all yelled.

"Happy late birthday bro." Said Apollo, patting Percy on the back.

"You have finally completed all your training, and it is time to celebrate your success." Said Hades.

Persephone hadn't said anything as she was drooling over Percy's fourteen year old body. He hadn't changed much, but he did grow taller. He was now 6 feet even with large muscles to match.

"We will eat cake, then open presents." Said Poseidon, walking all the way into the throne room.

Percy paused and looked around.

"We're is Hestia."

"Your girlfriend had some business to take care of. Don't worry, she will talk to you later, and more than likely give you her full blessing." Explained Apollo.

Percy was a little saddened by this. He was really hoping to get to see Hestia after not seeing er for three years.

Percy was interrupted from his thought when a piece of cake was placed in his hands. He nodded thanks to Persephone who nodded back. After eating cake and talking about Percy's different trainings, it came time to open presents. From Apollo, he got an awesome guitar that changed into a chain with a guitar on it. He also got a hunting knife forged from the sun and cooled in the vacuum of space. Also Percy got Apollo's full blessing so that he could never be blinded and see could people's heat signatures.

From Hades he got the power to raise the dead and something even better.

"Percy." Hades said. "I've been thinking, and I've decided something. I would like to make you prince of hell hounds."

To say Percy was surprised was a understatement.

"I-I except."

Hades raised his hand and a black glow covered Percy. When If died everyone gasped. Percy had changed from the power he received. His pupils were slits like a cat, his hair was longer and darker with a messier look that worked for him. He also grew another two inches, making him 6'2 and his muscles were more defined. He could hear, see, and smell better too and his canine teeth were longer and sharper. Persephone passed out and and the three other gods just stared.

"Well... Fuck. I need a haircut now." Said Percy.

"We'll get to that later." Hades waved his hand dismissively. "Right now try to picture yourself as a hell hound.

Percy did what he was told and when he opened his eyes he was three feet shorter and covered with black hair. He looked like an really large wolf.

"Is he supposed to look like a wolf?" Asked Apollo.

Hades shrugged and Percy changed back.

"Well that's awesome." He said.

"My turn!" Announced Persephone, who regained consciousness.

She held out two boxes and Percy took it and opened it. Inside one was an exact replica of what he was wearing. On top of it was a SnapBack hat with a trident on the front. Percy looked at the clothes he was wearing and noticed they got smaller since he got bigger.

"These clothes will change to your size as you grow and are fire proof so they don't burn." Explained Persephone

In the next box was three magazines for guns.

"Theses will go in your guns. I had them made by Hephaestus so that you will never run out of bullets again. If you flip the magazines the bullets change into plastic ones."

Percy thanked her for the gifts and went to change his clothes and load his weapons.

When he came out Poseidon asked him to kneel before him.

"Perseus Jackson. You have shown me your power in the sea and have made me think. I have come to the conclusion that you will not only receive my full blessing, but also the throne if I fade. You, Percy, are now my son and prince of the sea. Not only will the water heal you, but you shall be able to talk to all sea life and any form of horses. Do you except?"

Percy was beyond shocked. All he could do was nod and Poseidon smiled. Percy was bathed in a sea green light, and when it died he changed yet again. His hair was shorter (thank the gods) and he had a very nice tan as if he spent his time on the beach.

"And now, my next present."

Poseidon snapped his fingers and a sword appeared on the table. It was the best sword Percy had ever seen. Picture a Poseidon's trident. Now take the handle and cut it until it's about a foot long. Then remove the middle prong from the top and replace it with a four foot, double edge, blade. That's how you would explain the sword. Percy picked it up with one hand and swung it. Percy could tell it was heavy because even with his strength, the sword had some weight to it.

"It is made out a Primordial Steel, the strongest steel ever made. It will never wear out and will return to you if lost."

Poseidon handed him a scabbard to put the sword and Percy put it across his back before putting his book bag over it.

"Is there anything else you need Percy?" Asked Hades.

"Yeah. How do yall feel about giving tattoos."

Twenty minutes later, Percy had four tattoos. He had a tattoo of the hearth on the left side of his chest where his heart was for Hestia. He had another tattoo of a lyre on his left shoulder for Apollo. His third one was on his left shoulder, and it was a black skull for Hades. And his last one was a large trident that went from the base of his spine, all the way to the middle of his shoulder blades.

Everyone nodded their heads at the tattoos because of how nice they were.

They were talking about Percy's next job when a iris message popped up in front of Hades.

The person on the other end said something and Hades went even more pale

"Are you certain?" He asked.

The person on the other end said something else and Hades waved his hand through the message.

"What is it brother?" Asked Poseidon.

"Percy I need a favor." Hades said. "I need you to save my children."
