Hey all, this is ILoveThisStory with a brand new crossover story! It's between Naruto and the Percy Jackson and the Olympians/Heroes of Olympus. The idea just struck me after I read all seven books over again…and since I am a Naruto fan fiction writer, I thought I might give this a shot.

Well, here we go! Read and review!

A/N: The Naruto characters involved in the story are post-time skip (that is to say, the Shippuden versions of themselves)

Two men, one with silver hair and the other blond, stared each other down. They stood like that for a minute before disappearing in bursts of speed. They met in the middle of the training ground, the blond having caught the elder's fist and the masked man having caught the blonde's fist. They stood in a deadlock until the older man twisted both arms so that he had a grip on his adversary's wrists. He threw the younger man over his head.

The blond landed and launched three knives at the other man. The scarecrow like person simply drew one of his own and deflected three out of the air and then ducked as his adversary slashed at where his head should have been. He did a handstand that managed to knock the blond away and flipped backwards, launching the knife. The blond dodged the incoming projectile and made a cross hand seal.

"Shadow Clone Jutsu!" Naruto cried out. Three copies of him appeared in a shimmer of wind. His adversary, Kakashi, raised an eyebrow at the way they appeared.

"Seems like you're getting closer to mastering that move." He said conversationally. Naruto always shook his head as his clones charged.

"I've always been good at it. Pervy Sage taught me a lot on our trip…I'm choosing now to show it." Naruto replied while watching his sensei tear through his clones. Quickly, Naruto made several hand signs.

"Wind Style: Great Breakthrough!" he said. A large gust of wind was formed from Naruto's mouth, but it wasn't aimed at Kakashi. Instead, all the nearby trees started to fall on the Copy-Cat Ninja. Kakashi, however, simply jumped through the onslaught. He popped out of the rubble doing several hand signs.

"Fire Style: Fire Ball Jutsu!" Kakashi said. A very large and round fireball flew at Naruto, who appeared to be in the process of creating his jutsu. He wasn't fast enough, as the fireball crashed on his position. Kakashi landed, knowing his unpredictable student had something in store for him.

Indeed, it seemed that Naruto did have a move waiting for him. The flames, blazing uncontrollably, suddenly died out. Naruto stood in the center of it, holding up a small blue ball. The core was white-almost as if the essence of the wind was had been captured by the attack. Kakashi noticed this and started to make his own jutsu. In his palm, a ball of pure lightning started to form, with spidery arcs shooting from it and hitting random objects. A terrified field mouse that was fleeing was struck by a stray bolt and instantly keeled over.

"Is that your Wind Style: Rasengan?" Kakashi asked. Naruto nodded.

"I've been trying to make it bigger so it could do more damage, but for now I'll settle for testing it out against your Raikiri (Lightning Blade)." Naruto stated.

"Why do hide your strength?" Kakashi asked.

"Two reasons: to surprise my foes, and so that people like Danzo won't make me out as a threat. I've already had so many assassination attempts…I don't need his ROOT agents trying to take me out." Naruto replied. The two nodded, and on an unspoken signal, jumped at each other. Raikiri smashed against Rasengan.

But then, the strangest thing happened. The streams of wind and lightning stemming from the clash of the two powerful jutsu halted, and then reversed so that it seemed it was being absorbed by the two ninja.

"What's happening?" Naruto screamed over the noise.

"Not sure!" Kakashi yelled back. And then, even stranger, a figure-a woman by the looks of it- appeared over the two of them.

"You are needed in our world." The woman simply stated. Then, in a flash so bright that even Gaara the Kazekage could see, the two ninja were gone-gone as if they never were.


The two mystified ninja landed at the base of a green hill. Behind them stood the hill, and beyond that was what seemed to be a camp of some sort.

"Kakashi-sensei, where are…" The question died in Naruto's throat at seeing his teacher. Kakashi was alive and well…but he was also a teenager.

"Kakashi-sensei, what happened to you? You look…a lot younger." Naruto said. Kakashi looked into a nearby puddle to see his reflection.

"Well…I'm sixteen again, from the looks of it. I have no idea who the person was, how we got here, and where we are. Nor do I have an idea as to how I'm suddenly so young again. Stay on guard, though. We have no clue-"

"HYAH!" A girl's voice screamed nearby. The duo turned to see, about fifty yards away from them, four figures running towards them. Behind them, a nasty congregation of…monsters, for lack of better word, chased them. One of the figures looked like they were human, but he had donkey-maybe goat-legs. The other three were human.

The first one they saw clearly was a boy-fourteen, fifteen perhaps. The guy was Naruto's height and build, with short-cropped sandy hair, pointy nose and blue eyes. A scar ran down from just beneath his right eye to his jaw. He wielded a bronze sword and shield and was slashing at what had to be one of the biggest dogs the two had ever seen.

The second to come into visibility was a small girl. She couldn't be any older than seven. She was short with honey blond hair that reached to her shoulders. Her eyes were a stormy gray. She held a small bronze knife.

The final human to appear was the girl that had screamed. With black hair and green eyes, the girl had to be at least twelve. She probably would have looked beautiful, but dirt and grime was smeared all over her, as was the others. She had a bronze spear and shield with a face so ugly molded into it that the two flinched from the sight. As she yelled, a blast of lightning incinerated two snake women.

They looked like they hadn't seen rest in a few weeks. The monsters could overwhelm them at any time.

"We've got to help!" Naruto tugged Kakashi's arm as three of the figures- the guy, the small girl, and the goat man- abandoned the other girl. No, they didn't abandon her-she had ordered them to go. The goat man and the guy ran by Naruto and Kakashi, but the small girl stopped and started pulling at Kakashi's pants legs.

"Please help Thalia!" she pleaded. Kakashi looked at her and nodded. Naruto and Kakashi ran down while the girl ran into the camp.

As they ran, the girl speared another dog and whacked a flying hag away with her shield. Another yell by the girl, and a giant was blasted by lightning. But the two ninja could easily see that she was tiring. With each lightning strike she summoned up, her moves got sloppier and sloppier. Her shield was batted away by the hag. Her spear was broken in two by a giant's club. A snake woman knocked her away. She stood and started to run, with maybe two hundred assorted monsters chasing her.

Finally, Naruto and Kakashi leapt over her and into the path of the monsters. They recoiled, as if they were sizing up the newcomers. The girl kept running, but as she reached the top of the hill, she turned to watch what the two would do.

"Get out of the way!" One of the three flying hags demanded. "Lord Hades decrees it!"

"Who?" Naruto asked. The monsters stared at him as if he spoke in a tongue they didn't understand.

"Enough of this! Fire Style: Fire Ball Jutsu," Kakashi said, blowing a huge fireball at them. The hags flew away, but the fireball disintegrated about twenty monsters.

"Shadow Clone Jutsu!" Naruto said. Twelve clones appeared and started charging at them. The clones each had dual kunai knives and sliced through the monsters, but they wouldn't go away.

"You'll need Celestial bronze to kill them!" the girl at the hill yelled. Several warriors, all gleaming in bronze armor and wielding various bronze weapons, charged down the hill to help. A volley of arrows came down and took out about fifty more monsters. The warriors sliced through them easily. At last, only one of the hags remained.

"Hades will have your soul!" It cried. Kakashi snorted.

"Shut up. Fire Style: Phoenix Flower Jutsu!" he said. Several smaller fireballs pelted the demon until, with a loud wail; she exploded into yellow dust and debris.

All was silent for a minute, not believing what had just happened. Naruto, always first to recover, turned to the centaur that had pushed his way to the front of the crowd.

"What's going on? Where are we? And who the hell are you people?" Naruto asked. Once again, they stared at him as if they didn't understand his language.

The centaur turned to a group of warriors, all with blond hair and grey eyes, like the little girl the duo had seen before. "Do you recognize this language?" the horse-man asked. Most of them gave a negative response, but one of them stepped forward.

"It sounds like a rudimentary form of Japanese, Chiron." He said.

"Thank you, Mark." He said. "Campers, back to your activities!" The warriors and a few other people that had come to provide aid but never joined the battle trudged off in groups of twos and threes. Finally, the hill was cleared of all but Chiron, Naruto, Kakashi, Thalia, the satyr, the blond guy, and the small girl.

Chiron glanced at the strange assortment of figures as if he had not an idea as to what to do with them. "Come," he said at last. "Let's talk about this."


The six of them sat side-by-side, with Chiron standing in front of them. The centaur paced back and forth while his tail swished around nervously.

"Before we begin, I'm going to put a spell on you two. You can understand us, but we can't understand you, which is a major problem. My spell will allow you to speak our language." Chiron said. Naruto and Kakashi glanced at each other before nodding.

Chiron started to mumble something in a language they didn't know-though Kakashi suspected it was Greek. He'd passed over the Greek culture once or twice in the library, and if the name Hades meant what he thought it meant, than what Chiron was saying was most likely Greek. It mattered none, however, as neither of the two ninja had any clue as to what Chiron was doing to them. When nothing happened, however, Naruto spoke up.

"What was that supposed to do?" he asked. Chiron nodded.

"Well, it was meant for you to speak our language, and it seemingly worked. Now, who are you two?"

The question was simple enough, but Naruto looked at Kakashi for advice. The more experienced ninja knew that giving away information to people you didn't know was never a good thing, but these people had helped them battle off the monsters, so they couldn't be all bad.

"My name is Kakashi Hatake, and this is one of my students, Naruto Uzumaki. We are two ninjas from the Village Hidden in the Leaves."

"Hold up," the guy who was identified as Luke started. "Ninjas? And what is the Village Hidden in the Leaves?"

"Hmm…well, in our world, ninja are like your warriors. There are five great villages-one of which is the Village Hidden in the Leaves- and several smaller villages. Most of these villages have ninja to protect it from invasions, as well as take on missions to gain revenue. Almost every village is hidden by something. For example, there's a Village Hidden in the Mist. Our village is hidden amongst leaves."

"So how strong are you guys?" Thalia asked.

"Well, our ninja is divided into ranks. Genin, like Naruto, are pretty weak. Chunin are like the middle class. There is Special Jonin, which are ninjas that show the skill to be something greater than Chunin but not quite Jonin. Then there is the Jonin, like me, which take on most of the most dangerous missions. Above us is the ANBU-kind of like the Secret Service, the ANBU take out covert missions. I was once an ANBU. Finally there are the Kage, which is the strongest ninja in the village. Naruto may just be a genin, but he's definitely as strong as a Special Jonin, maybe even Jonin. I'm at ANBU strength."

Chiron flicked his tail. "So how did you guys end up in our world?"

Naruto and Kakashi glanced at each other.

"Well," Naruto began, "Kakashi and I were sparring together, and we used our strongest moves to see which was stronger. The resulting explosion sent us here. Also, a strange woman said that we would be needed here, and then we just appeared here."

"Hera, perhaps?" Chiron muttered under his breath. "Never mind that." He then turned to the three demigods and the satyr. "So, if I recall correctly, I sent Luke out to retrieve a demigod one of our satyrs had found. This demigod, whose name is Thalia, turned out to be a daughter of Zeus, the Lord of the Sky. Apparently, Hades, the Lord of the Dead, was not pleased by this, and sent his most bloodthirsty monsters after you two. Along the way back here, you two met little Annabeth, who is also a demigod. The three of you met up with Grover, and the four of you came back here chased by monsters. Apparently, at the bottom of the hill, Kakashi and Naruto just appeared to find you all being overwhelmed by the monsters. Thalia told you all to go, but Naruto and Kakashi stepped in and bought us enough time to help fight off the army. Correct?" Chiron recapped. Everyone nodded, and Chiron sighed once more.

"Well…welcome to Camp Half-Blood!"


The six walked away shaking their heads from the tour Chiron had just given them. They had seen everything: flying horses, dryads, naiads, and Mr. D. Who knew that he was a god?

"So, what were those things that you all did back on the hill? That was awesome!" Grover started out.

"Oh, us? That was called jutsu- a special move we can pull off by using our chakra, the energy that keeps all of us alive." Naruto said.

"If w all have it," Annabeth said for the first time, "then can we do those moves?"

Kakashi and Naruto looked at each other. They hadn't thought of that possibility.

"Hmmm…well each of you have a different chakra, so you'll only be able to pull off jutsu pertaining to your chakra. Luke is a son of Hermes, and they seem to have the chakra for genjutsu-that's like illusions, and trickery. Annabeth…hmm, you can pull off purely chakra moves, like Naruto's Rasengan. I wonder…you might be a child of Athena, since all their campers can only do what you can do. Thalia will be able to do Lightning jutsu, being the daughter of Zeus and all. Grover…he's not a half-blood, so his chakra is different from ours. But if I'm sensing it correctly, then he can do just about anything pertaining to nature."

"Hold up," Thalia stated. "We have the same chakra, correct? So then, shouldn't you two be half-bloods as well?"

Naruto shrugged. "Maybe. Who knows what happens when you jump from world to world."

So, of course, everyone stopped and gasped at Kakashi as a lightning bolt appeared over his head.

"I guess we are half-bloods, then." Naruto stated as he started kneeling.

"All hail Kakashi, son of the Sky God." Thalia announced grimly.

"Just amazing." He sighed, pinching the bridge of his nose. He had a sister.


Two weeks after Kakashi had been claimed, Chiron had tried to get Naruto a weapon that suited him. During the last capture the flag game, Naruto didn't have a weapon that suited his style and had to resort to his kunai knives.

"So Naruto, you feel comfortable with the iron knives?" Chiron asked. Naruto slowly nodded.

"It feels most comfortable, but there's something off about it…like it's missing something."

"Try this." Chiron said, handing him a six-inch knife with a three-inch hilt. Naruto gripped it, but shook his head.

"It's something about the Celestial bronze that I'm reacting negatively to…" Naruto said, putting the knife down. He picked up a three foot long bronze sword with a beautiful hilt. Again, he shook his head and put it down. Chiron tossed him a bow and some arrows.

"How about this?" he asked. Naruto, unsurprisingly, shook his head once more. Chiron groaned.

"That's everything that we have. Perhaps you simply aren't meant to kill monsters with a weapon?" he asked. Naruto shrugged, but stopped as he spotted two weapons that he felt attracted to.

They were twin daggers, each blade seven inches long and as dark as night. The hilt was four inches long and was designed almost the same as the kunai knife's hilt was. It was nothing fancy, but Naruto walked over to them anyway.

"Oh, I wouldn't do that! Those are Stygian iron blades, only handled by children of Hades." Chiron warned. Regardless, Naruto picked them up and gave a few experimental swipes.

"Perfect." He said. He channeled his chakra into the blades. They became dark blue, with a light blue two-inch extension coming from the top of the blade. He threw one with deadly accuracy into the ground. Immediately, bones starting coming out of the ground and started knitting themselves together.

The finished product was gruesome but beautiful. A skeleton stood up, dressed as a New York City police officer. The flesh covered the bones, but it was so white that it appeared to be blue. Its expressionless face stared at Naruto, waiting for an order.

"Um…you can go away now?" Naruto tried. The skeleton sunk back into the ground as quickly as it came.

"But…how?" Chiron spluttered. Then he gasped. Naruto looked up and couldn't help but grin.

The helm of darkness floated over his head.

He was Naruto, the son of Hades, Lord of the Underworld.
