I do not own Naruto or Percy Jackson. This is just a fan-fiction story.
Long before the Greek gods existed, there was the first Devine being. He was once called Naruto Uzumaki, but now he is known by many names. The creator. The first primordial. But by most people, he is known as Chaos. Unknown to even the gods, he was once part of the elemental nations, but that place was flawed. There was never true peace. So after absorbing the powers of Kaguya, the Devine beings of that realm, Kami, Yami, and Shinigami approached him and asked him to absorb them and correct this flawed world. He agreed and after absorbing them, he became a god. He absorbed all the chakra in the world and destroyed the elemental nations. Then he created a new world. A world with the underworld to punish or reward the dead for their actions on earth. Then he created the first living beings on the Planet. The primordial, Gaia, Ouranos and Tartarus. And then he created humans, with no chakra this time, and the mist, to hide the Devine and non humanly actions going on. He had used up a lot of power after creating an entire world, so he went to rest below Tartarus, in a place named after his new name, Chaos. In there he would observe the world and see what happened in it through the times. He would also train in his mindscape, making him infinitely stronger.
1 million years later.
Naruto yawn "Hey Kurama! How long have I been asleep?" "A million years kit" said Kurama.
"Whaaaaatttt!"
"You are a god for sage's sake. You are the first and ultimate Devine being and the last one with chakra, and you don't know how long you have been sleeping?"
"Uhhhh, I guess you are right. So now who exactly is ruling the world right now?"
"Zeus and the Olympians. They call themselves gods."
"Right. Now I remember. Let's go give them a visit shall we? I wanna see how things have been going on"
"Let's go kit. Let's have some fun."
"Sure."
Naruto/ Chaos teleports in front of the doors of the Olympian throne room where they have been fighting over who stole Zeus' master bolt. Chaos opens the door and walks in wearing a orange and black hoodie with black pants and black Nike shoes.
All gods stop talking and stare at the hooded man entering the room.
"Who are u and how dare you interrupt this meeting? I will kill you for this!" said the king of the god, Zeus.
"I thought the king of the gods should know stuff. Well, I can't really blame you."
"How dare you!" he shoots a powerful lightning bolt at Naruto that would incinerate a mortal.
Naruto smirks and catches the lightning bolt between his 2 fingers. All gods are dumbfounded and Zeus is fuming. Naruto then starts growing in size till he is even bigger than Zeus. He then throws the lightning bolt back at Zeus who gets hit and is in pain.
"Wh-who are you?" asked Athena, the goddess of wisdom with fear in her eyes. Something she has not felt in a really long time.
"Me?" said Naruto as he slowly pulls down his hood. "I am Zeus' great grandfather. I am Chaos."
All of the gods are shocked. They are speechless. "Oh don't worry. I am not here to erase you all from existence or lecture you on how you should be treating the mortals." He continued, "I am just here for a nice family reunion. Uhhhh leaving out the titans and giants and demigods and minor gods. Wait. Someone's missing." he snaps his finger and both Hades and Hestia appear.
"h-how do did I get here?" said the the god of the underworld. "I don't know." continued Hestia.
"I brought you here" answered Chaos.
"And who might you be?" questioned Hades.
"I am your great grandfather, Chaos, and judging from the glares that we are getting by the rest of our family, we are not really liked."
"You got that right."
"Hello Hestia."
"Hello great grandfather" said the goddess of family
"At least someone here has respect for family." said Chaos wiping off a fake tear from his eye. "Now, back to business. What is the fuss going on here?"
"Someone sole Zeus' master bolt and he blames Poseidon for it." blurted out Apollo. "Apollo, shut up. We don't even know if we can trust him yet." said Athena
"You can't even trust your family? No wonder this is the most complicated and problematic family in the world."
"What do u mean by that?" asked Hera a bit frustrated.
"This is what I mean. Hades is neglected and hated by the rest of the family except Hestia. Hestia isn't even remembered anymore. Dionysus is grounded for a hundred years. Artemis hates boys. Hephaestus got rejected by his own mom. Apollo is cool but an idiot and flirts with everyone possible which gets him into trouble. Ares is just too thick skulled. The only thing Demeter likes is plants. Aphrodite only cares about her looks and is cheating on her husband freely. Hermes. Man you got to make people respect you. They treat you like a walking email. Athena. I know you got angry when water boy messed around with his girlfriend in your temple but was it really necessary to turn her into a snake haired monster that turned people into statues. You just gave demigods one more problematic monster to deal with like they didn't have enough already. Poseidon. You know bedrooms exist for multiple purposes right? Was it necessary to use Athena's temple? Hera. I know that you are the goddess of marriage but remember. You are also the goddess of women so if Zeus keeps cheating on you so what? It's not like it is ever going to change. So live your immortal life to the fullest and screw Zeus, and sometimes just remember, even though you are gods, marrying your brother is just wierd. According to me ya'll should get a divorce already. And finaly, thunder boy. The biggest problem in the family. You really need to remove that massive stick that is up your ass. All you do is think that you are the greatest power in the world but you are not. You cast down your own family to earth multiple times for reasons they didn't deserve. You cast Hades down to the underworld and all of you hate him. He does not even have a seat in Olympus. He did nothing to ya'll yet he is treated like an outsider. If you all think that he is evil then he is not. Zeus you get angry at every small thing but you need to realize that being humble will make you a good king and your aragonce and your paranoia that people want to over throw you will be your downfall. It was your father's downfall and your grandfather's and if you do not change, it will be yours."
"That, was beautiful. You were so subtle about it that I didn't even understand if you were roasting us or trying to correct our mistakes." said Hestia.
Poseidon and Hades burst out into laughter. "Hear that brother, you need to get rid of that massive stick up your ass." teased Poseidon. Zeus just shot them a death glare.
"But in all seriousness." continued Chaos. "You gods treat mortals like garbage. That needs to change. And most of you don't even care about your children. I am not telling you that you should visit them daily because I know you all are bound by ancient laws and cannot visit them directly, but there are a number of ways you can make them know that you love them, because one thing that you all should know is that if you don't treat your family like one then there will be problems. Kronos and Ouranos have experienced that, and I dont want you to be the next one Zeus. Also, Hades, Hestia and I will get seats in Olympus because Hades and Hestia are a part of the family and Hestia will need to keep the family together. so there will be 15 Olympians now."
"Hey who are you to tell us what to do and what not to? You are not even a god!"
Naruto sighed and raised up his hand. Suddenly, Area came flying out of his chair and came towards Naruto. He pulled back his fist and delivered one straight punch into Ares' gut, knocking the air out of him. " See, this is what I meant by thick skulled, after all my lectures. I am the oldest and strongest member of your family, so show me some respect, or I will have to knock some sense into you, brat." Ares dropped unconscious. "Athena, please knock some sense into your brother. Hera, make sure to remove that stick that is up Zeus's ass. Poseidon and Hades, help her out. Your brother is more stubborn than Tarturus. As for the rest of you, get to know Hades, trust me, he might get a bit dark sometimes but he is a cool guy."
Everyone just nodded, being shocked at how powerful he was to knock Ares out in just one punch. "How do you know so much?" asked Athena.
"When I was sleeping for these million years, I wasn't just sleeping. I was observing what was happening through the times and training in my mindscape."
"Training?"
"Yes. Training."
"Why?"
"To get stronger and get beter control over my powers which are endless so I always train."
"But you are already so strong. You knocked Ares out in just one punch."
"I am really strong but there can be threats in the future. Even though they might not be as powerful as me, they can always have some tricks up thier sleeves, besides, training is more like a hobby to me. You gods never train thinking you are perfect, but you are not. Nobody is. Not even I am perfect."
"I understand."
"You know, I could always train any of you to get better control over powers."
"How can you train us in our domains?" asked Artemis.
"You are forgetting Arti, I created everything, including this planet, the underworld and Tarturus. I have control over every domain and I have mastered all thier powers." Chaos replied. "Let me show you something." Just as he said this, a chair made of plants, wood and grape wines sat down on it as half of his body started glowing like the sun and the other half started emiting moonlight. He held out his right hand in which a ball of energy started forming. Then it started glow pink as fire, water, lightning, wind and small rocks started spinning around it. Beside him two skeleton guards appeared with a spear and a sword. The first one sat on a boar while the second one sat on a cow."
"Whoa. You weren't lying. Can you please train me super Gramps?" pleaded Apollo with puppy dog eyes.
"Sure. You might even become stronger than Zeus, but he will remain the king of the gods and you will not try to overthrow him ok?"
"Ok!" said Apollo with a huge grin on his face.
"Stop acting like a child Apollo. Super Gramps? Really?" asked Artemis.
"I don't mind." said Chaos while Apollo just pouted.
"How do u have such mastery over our domains even more than us? I am sure even father cannot control lightning to such a degree." asked Artemis.
"I told you. I have been training for a million years. Also, I know a lot of things. I can even read minds. So I know exactly who stole your lightning bolt."
"Who is it?" Zeus boomed.
"There you go again with your dominating attitude. You really need to learn how to chill. Learn something from Apollo or Poseidon."
"Apollo and Poseidon I demand you to teach me the art of chilling." Everybody's sweat dropped."
"I wont tell you who stole it because it will be nice quest for the demigods, and Zeus, do not blame any god or demigod or even threaten them if you don't know who is the true culprit." Chaos said releasing killer intent towards Zeus who got a cold shiver down his spine."
"Y-yes."
Poseidon burst out into laughter, "Look at the mighty Zeus scared." Everybody just chuckled while Zeus shot him a death glare.
"I will start training all of you and the demigods after your toy is returned Zeus." said Chaos.
"It is not a toy. It is the most powerful weapon in the entire world." complained Zeus.
"To me it is just a toy. I will give you an actual weapon after you learn to be humble and get rid of that stick up your ass."
"Tch."
"Anyways, I will see you all later when the bolt is returned. Till then treate Hades nicely and Hestia make sure that the family stays together. Byeee!" he said as he disappeared in black flames.
"That was-" said Hera.
"Wierd." replied Athena.
"Cool" argued Apollo.
"Awesome. He totally roasted Zeus ass." said Poseidon grinning. While Zeus just glared at him.
"Huh. POSEIDON! Return my lightning bolt!" said Ares as he slowly woke up. Then he fell asleep again. Everybody just chuckled and face palmed.
