Hey everybody! It your favorite person GodoftheSeas21 here!

I was thinking about discontinuing this story so I can see SeaweedBrainLuva3 explode. Just kidding! But you can explode if you want to. Haha

I'm very sorry I haven't updated in a while. So let's get started already, shall we?

The Hero has Returned.

3rd Person POV

The following day for the campers was the same that it has been for the past few days, training. Mark, Clarisse, and the rest of the counselors were all teaching melee combat in the sword arena.

But there was something different about the training that the campers were used to. Their parents were in the stands watching them each closely. They were trying to figure out if or how they could win this war.

Some of the campers were really getting the hang of it, but there was still a few that were not getting the hang of it.

"What the Hades are you guys doing?" Mark yelled, "You are still doing it wrong!" many of the counselors and the campers started getting angry at the counselor of the Poseidon cabin. Clarisse is not even yelling at the campers.

The gods sat in the stands watching the training. When they saw how much Mark was yelling and cursing at everyone they were appalled.

"You are a bad teacher!" one of Mark's siblings yelled at him.

"You dare call me a bad teacher? I'm teaching it right...you're just doing it wrong."

"Altair said there is no such thing as a bad student! Only bad teachers!" another Poseidon child said.

"I want Altair to teach us again!" An Ares camper yelled. The gods were shocked, when did this assassin take the time to teach some of the half-bloods how to fight.

"What does that assassin know about fighting!" Marked screamed at them. He started walking up to the camper when a silver arrow landed at his feet.

Everyone looked at were the arrow came from. It was the one man that most of them wanted to see. He was wearing his usual black with sea green trim robe, silver armor, and all his weapons strapped to him.

When Artemis saw him her heart fluttered a little. She remembered his sea-green eyes, they had pain but also beauty. She thought of his soft and passionate lips. She found herself holding her own lips and staring at the great hunter with dreamy eyes.

He slowly walked toward everyone, but Mark met him in the middle.

"Who the fuck do you think you are?" Mark screamed as he pulled out Riptide and slashed it at Altair. The assassin sidestepped easily and punched Mark in the side. Then used his foot to sweep Mark's leg out from under him, and the son of Poseidon fell on his back.

"You are very Predictable...you only know how to attack." Altair said

"AHHHHHH!" Mark screamed as got up and tried to slash at the assassin again, but Altair did something very unexpected. Instead of sidestepping, which he would have been able to do easily, he caught the sword with his bare hand.

He rapped his fingers around the blade as Mark tried to pull the sword back, but failed under the assassins strong grip. Altair ripped Riptide out of the son of Poseidon's hands and tossed it to the side.

Everyone's jaw dropped, the one thing that all of the onlookers noticed was that there was no blood on his hand or the sword. Riptide was one of the greatest swords in the world, a swipe from a strong Mark would easily cut of a hand, of at least make a small cut. But not a single drop of blood fell. That could only mean one thing, he had to be invulnerable.

While Mark stood still, dumfounded by what he just saw. Altair kicked him in the chest and he flew seven feet backwards landing on his back and sliding another five feet on the dirt. Everyone just looked at the assassin then at Mark, the did bother going to help him up. No one liked him, but many of them were scarred of him.

"You DARE hit ME!" Mark yelled as he got up slowly. Altair just chuckled

"I'll beat you anywhere, and at anytime."

The clouds started to blacken and it started to rain. Everyone started to grumble about get wet, well except for Aphrodite and her children who screamed.

The gods all noticed that Altair wasn't getting wet, more and more their suspicions were coming true.

"How about right here, right now." Altair chuckled and nodded. Everyone else hurried over to the seats of the arena.

Over 200 demigods, dozens of nymphs and satyrs, and the Olympians all wanted to watch this duel of two good fighters.

Mark picked up Riptide and pressed his watch that turned in a big bronze shield. Altair pulled out the two two-foot swords from his back, and stood facing the demigod with an amused face.

"Are you ready?" He asked Mark. He just pointed his sword at the assassin signaling that he, indeed, was ready.

"Well, then what are you waiting for?" Mark charged instantly, slashing at the assassin with extreme hunger. Altair dodged the attacks as if he wasn't even worried.

Mark kept up the attack, slashing at Altair's neck. Altair ducked under the blade and used left blade to slash at the sea gods son, but it was blocked by his shield.

Altair didn't hesitate by his attack being blocked. He immediately came back with his right blade, causing a deep cut in Mark's left shin.

He cried out in pain from the cut, and stumbled backwards. Altair got up and readied his blades. After the shock of being injured, Mark went on the attack again, this time using his shield on offense instead of defense.

Mark stabbed at the assassin, then when Altair blocked his sword attack he hit him with the shield.

Altair stumbled but quickly regains his composure, dodging and rolled from another attack that came from the ego filled manic.

The blade missed Altair's chest by about an inch. It wouldn't have even hurt, or even caused a scratch, but it would have proved that Mark could hit Altair.

The blade landed in the dirt in front of the assassin. Mark tried to quickly slash upward but Altair rolled out of the way.

The two battled on for about ten minutes until Mark started to grow tired. He had cut all over his body, while the assassin did not have a single scratch on his body.

"A great warrior has to have stamina." Altair chuckled as he saw Mark heaving and putting his hands on his knees. "But I'm not surprised that you don't have any."

When Altair finished talking he threw the two swords at Mark. The second one he managed to block with his shield, but the first one was just to fast. It managed to slip past before he was able to get his shield up in time and grazed his shoulder.

Mark screamed in pain again, it already had over a dozen cuts from this battle, and this just make in one more.

He decided to charge while Altair didn't have any weapons out. Clearly he forgot about Altair hidden blades that could pop out any any given time, but Altair was having far to much fun to use his best weapons.

Mark slashed and stabbed at Altair but all he could manage was air. He tried to bash the assassin with his shield but Altair just grabbed it twisted Mark's arm behind his back. Altair then twisted back around, causing Mark to let go of the shield.

Mark stumbled backwards and fell, landing on his back. Altair started walking towards him slowly, trying to savor the moment of finally getting revenge on that little ego filled jerk that took everything from him.

He tossed the shield to the side, with a big mischievous grin on his face. Altair then changed his course, he started circling the son of Poseidon.

"A hero doesn't let his voice tell everyone how good he is...a hero lets his skills show it."

"Your nothing!" Mark tried to yell as blood started pouring out of his mouth and down his chin.

"If I'm nothing then what are you? I know my skills...i know just how good I am...but I also know that I can't underestimate my opponents...no matter how weak they are." Altair said the last part of the sentence with a smirk.

"I will defeat you!" Mark yelled again.

"You are never going to get it through that big ego filled head of yours, are you? A hero must be humble...if you are not humble you will never reach your true potential." Everyone pondered this for a moment. Athena couldn't get out the fact that if this is who the gods think it is, then he has become very wise indeed.

"Just as myself...i have been trained by Chaos himself...many of the universe's most powerful people fear me...but I also know that anyone could bring me my death, no matter who they are, weak or strong."

"Ha...if you're SO strong then no one should be able to defeat you."

instead of answering Altair just pulled out his sword. A four foot long deadly blade that has tasted much blood.

Mark got up and charged the assassin. He was either brave or foolish to to charge but he did so anyway. Slashing left and right, Mark was blocked every time.

The angrier he got the more his attacks missed. Mark took another swipe, this time at the face of Altair. The assassin saw it come even before Mark thought of it. He ducked under the attack, spun around and slashed Mark across the stomach. It was just a small cut, Altair made sure to not make any wounds that would kill Mark, just injure him.

Mark stumbled back holding the new cut across his stomach.

Rain was still pouring down. The Arena was nothing but a huge pit of mud. Mark started slipping, he got so furious that the ground started shaking.

Everyone was soaking wet and fell down because of the violent shaking of the ground. It was an earthquake, and a violent one.

There was only three people that did not fall down: one was Poseidon, another was Mark, and the last was Altair.

How could he not fall from something as bad as an earthquake?

Everyone regained their composure after the earthquake died down. But they did notice that Altair was unaffected by the power of Mark.

"How is it that did not affect you?" Mark yelled

Altair said nothing and that made Mark get more furious, he put Riptide back in his pocket.

"Let me show you the power of the sea!" Mark yelled at the top of his lungs. A huge wave came from the ocean and flew at the assassin.

But then something happened that no one expected. Just when the water was about to hit Altair at full force, it stopped. It stopped an inch from him.

Everyone's jaws were on the floor, he can control water. While Mark was lost him shock the water shot back at him at great speed. It sent him flying back twenty feet before he hit the ground and skidded into the wall.

The faces on the campers were priceless, but it got better when they noticed that the clouds disappeared and the rain stopped.

The Olympians walked down into the arena as did the other campers and Altair walked to them.

"How did you do that?" Annabeth asked.

"You mean you haven't figured it out, Wise Girl?" He answered with a smirk.

"But how does he know the name that Percy ga-" she said in her mind, then her eyes went wide. It could be? Could it?

"Percy?" Annabeth asked in a small but hopeful voice.

Altair said nothing, but he pulled down his hood to reveal long and messy back hair. Everyone, except for Artemis, were finally able to see his eyes.

The Olympians and the immortal counselors gasped. Altair then pulled of the mask that he wore on his face, it revealed three scars across the right side of his face. Everyone gasped again. Tears started forming out of Annabeth, Thalia, Poseidon, and Artemis' eyes. Nico and Grover's faces lit up lighter than the sky on Fourth of July.

Their wishes have come true.

Altair was the hero of heroes, the favorite son of Poseidon, Altair was Percy Jackson.

The hero has returned.
