Chapter 8: The Mother of all Monsters

After the incident with Madusa, they left the warehouse and camp out in the out doors as Annabeth fell asleep, Percy and Grover were having one of their talk and heard that Grover is aiming to find, Pan who is the God of the Wild like all other satyrs and Naruto just decided to stay up all night to be a lookout all night.

As Naruto looked down from his point of view and looked at the trio that now sleeping like babies and thought, 'They really impress me as human beings, their not prejudice, judgmental and self-obsessed. Why do I feel safe around them and what is this feeling when I see them, is this what you feel when you have friends?'

As Naruto decided to let that thought go and decided to continue keeping watch.

~Next Day~

The weirdest thing happen the first thing they got up, they were talking to a poodle and let's leave at that since it might be consider weird and stupid and that he thought that he was on drugs or something, but there's also the fact that he discovered that he can talk to animals and wasn't surprised since he is the son of the goddess of Hunt and Wilderness. But the weirdest thing was that the poodle gave them direction to a train station which is an hour walk their and didn't know either to be thankful or thinking that he is crazy about non magical or summon animals talking to him.

An when they found the owner of the dog, the owner was squeezing the life out of it and strangely enough of the Daimyo wife and her cat, Tora the Cat from hell. But shakes it off and he the trio decided to head to train station and get on with their quest. After arriving at the train station and then paid their tickets to a train to Saint Luis which is about a two day trip and headed to the train and their journey continues on.

~Train~

For the next two days, they road on the train and the good thing was that they had not run into any monsters.

Naruto has told them about the Second Hokage named Tobirama Senju where he was one of the greatest water user in shinobi history where he could use his water techniques at any time, even if lacking a pre-existing water source by instead creating considerable quantities of water or else use the moisture in the surrounding area to follow up with other could further manipulate water by isolating areas within it and evaporating it at will. This got all three interested since no demigods of any sea god including Posideon and even himself can't produce water since they need water from seas and lake to fight and Percy wish he can do that.

They also learned that Tobirama Senju was told him that he was also one of the greatest sensor in history where he can detect from miles away. They also learned that he created some of the most feared and powerful jutsu in Shinobi history today like Shadow Clone Jutsu, Edo Tensei, Space-Time ninjutsu or Hiraishin no Jutsu and half of the water jutsu Naruto use's. They also learned that he created village's infrastructure and organisations like the Chūnin Exams, Anbu, Ninja Ranks,Ninja Academy and many other things as well. And Naruto told them that he died in the first shinobi world war where he be a decoy and sacrifice himself against 20 of Kumo elite soldiers known as the Kinkaku Force to let his students escaped and surprised them that Danzo was one of his students. Never the less, they have came to admire the Second Hokage and respect as a leader and also a hero.

But on the way to their destination, Naruto and Percy saw some odd things, like a family of Centaurs riding alongside them and one of them, the kid who looked like a second grader on a house, waved to them. While Percy looked to the adults to see if they saw, Naruto just smiled and waved. One other thing they saw a large golden lion, but they knew lions were not in America.

Right now however, he and the other were dumbly looking at a newspaper article. It had a picture with the four of them on it, Percy had a wild look and Naruto had a emotionless face on his face. The article read:

Twelve-year-old Percy Jackson, wanted for questioning in the Long Island disappearance of his mother two weeks ago, is shown here fleeing from the bus where he accosted several elderly female passengers. The bus exploded on an east New Jersey roadside shortly after Jackson fled the scene. Based on eyewitness accounts, police believe the boy may be traveling with three teenage accomplices. His stepfather, Gabe Ugliano, has offered a cash reward for information leading to his capture.

"Oh that is just terrific!" Naruto commented sarcastically.

"Don't worry," Annabeth reassured them "Mortal police could never find us." For some reason, she did not sound all that sure about it.

When they tried to sleep on the train, Naruto decided to go back to sleep and relived one of his memories.

~Flashback~

'It's been a month now since Sai was assigned to join the academy as undercover to try and recruit some new blood in Root, and since he was assigned with Sasuke Uchiha is more perfect now since we might have an Uchiha here now,' thought Naruto as thought of his partner getting reassigned to a different mission.

As he was summoned by Danzo for a mission that was important. As he arrived at the main hall of Root and saw Danzo and headed towards and kneel in front of him.

"Kitsune, I got a mission for you," said Danzo with authority.

"What is this mission my lord," responded Naruto.

"You will be assigned with to follow Sai's team to Nami no Kuni and make sure that the bridge builder is safe and protected."

"Lord Danzo, is there another reason why you sending me sir."

"Yes there is Kitsune," said Danzo. "I'll got word from Sai that he and his team encountered Zabuza Momochi who is working with Gato from Gato company and he is there and aim to kill the bridge builder. Your mission is too assure Sai and his teammates success on completing this mission and also to assassinate Zabuza Momochi and Gato, do you understand Naruto?

Naruto nodded.

"Good, dismissed."

~Flashback End~

"Naruto, Naruto wake up," said Annabeth as she began to shake him to wake up as Naruto began to open his eyes and saw Annabeth looking at him. "We're here, it's time to go," and Naruto nodded.

As they got all their things and left the train and now has arrived in Saint Luis.

~Saint Luis Arch~

The train pulled into the Amtrak station downtown. The intercom told them they would have a three-hour layover before departing for Denver.

Grover stretched. Before he was even fully awake, he said, "Food."

"Come on, goat boy," Annabeth said. "Sightseeing."

"Sightseeing?"

"The Gateway Arch," she said. "This may be my only chance to ride to the top. Are you coming or not?"

The boys exchanged looks. Naruto shrugged, he like seeing new things. Percy didn't want to but he was bored and he didn't feel like letting her go alone. Grover shrugged. "As long as there's a snack bar without monsters."

"Don't really care, I should pay since you guys lost your stuff back at the bus with the Furies." Naruto said and the others shrugged.

The Arch was about a mile from the train station. Late in the day the lines to get in weren't that long. They threaded their way through the underground museum, looking at covered wagons and other junk from the 1800s. It wasn't all that thrilling, but Annabeth kept telling them interesting facts about how the Arch was built, and Grover kept passing the two boys jelly beans, so it was not all bad.

Percy kept looking around them and asked Grover, "Smell anything?"

The goat man took his nose out of the jelly-bean bag long enough to sniff. "Underground," he said distastefully. "Underground air always smells like monsters. Probably doesn't mean anything."

"I don't sense anything either." Naruto shrugged.

Percy thought about it and said, "Guys. You know the gods' symbols of power?"

Annabeth had been in the middle of reading about the construction equipment used to build the Arch, but she looked over. "Yeah?"

"Well, Hade—"

Grover cleared his throat. "We're in a public place... You mean, our friend downstairs?"

"Um, right," Percy said sheepishly. "Our friend way downstairs. Doesn't he have a hat like Annabeth's?"

"You mean the Helm of Darkness," Annabeth said. "Yeah, that's his symbol of power. I saw it next to his seat during the winter solstice council meeting."

Percy asked Annabeth, " He was at the solstice?"

She nodded. "It's the only time he's allowed to visit Olympus—the darkest day of the year. But his helm is a lot more powerful than my invisibility hat, if what I've heard is true..."

"It allows him to become darkness," Grover confirmed. "He can melt into shadow or pass through walls. He can't be touched, or seen, or heard. And he can radiate fear so intense it can drive you insane or stop your heart. Why do you think all rational creatures fear the dark?"

"But then ... how do we know he's not here right now, watching us?" Percy asked nervously.

Grover and Annabeth exchanged looks before saying, "We don't."

"Thanks, that makes me feel a lot better," Percy said sarcastically . "Got any blue jelly beans left?" Grover nodded and gave him some.

It seemed Percy was calm until they had to get into a small car that would send them up the Arch. Naruto groaned inwardly, He knew Percy hated small spaces but they had to use that to go up so he put a reassuring hand on the younger boy's shoulder. Percy smiled a bit at that. They got shoehorned into the car with this big fat lady and her dog, a Chihuahua with a rhinestone collar and she seemed to a baby fox as well with the same collar. This lady and her pets put Naruto on edge for some odd reason, maybe it was because none of the guards had said anything about the animals or the strange energy he felt.

However, the arched elevator was not helping their stomachs at all.

"No parents?" the fat lady asked.

She had beady eyes; pointy, coffee-stained teeth; a floppy denim hat, and a denim dress that bulged so much, she looked like a blue-jean blimp.

"They're below," Annabeth told her. "Scared of heights."

"Oh, the poor darlings." She commented.

"Aw don't worry about it. "Naruto said. "They didn't want to spoil our fun, so they told us to go up without them." The lady just nodded to that.

The Chihuahua and the baby growled. The woman said, "Now, now, my darlings. Behave." The dog had beady eyes like its owner, intelligent and vicious. The fox looked quite agile and intelligent.

"Cute fox." Naruto smiled and she smiled as well but the fox growled a bit, seemed that it did not like to be called cute.

At the top of the Arch, the observation deck reminded them of a tin can with carpeting. Rows of tiny windows looked out over the city on one side and the river on the other. The view was okay, but it was making Percy and Naruto sick a bit. High places and closed spaces didn't mix well for them.

Annabeth kept talking about structural supports, and how she would've made the windows bigger, and designed a see-through floor. She probably could've stayed up there for hours, but luckily for the boys, the park ranger announced that the observation deck would be closing in a few minutes.

Percy quickly steered them to the elevator but he and Naruto could not get in because there was already to many people there. "New car you two." The park ranger said.

"We'll get out," Annabeth said. "We'll wait with you."

See thing was going to mess everything up, Percy shook his head and said, "Naw, it's okay. I'll see you guys at the bottom. Besides, if anything happens, Naruto has my back, right?"

"More like keeping your ass in check," replied Naruto and Percy just smile and rubbed the back of his head.

Grover and Annabeth both looked nervous, but they let the elevator door slide shut. Their car disappeared down the ramp.

The only people left on the observation deck were Percy, Naruto, a little boy with his parents, the park ranger, and the fat lady with her Chihuahua and the baby fox.

Percy smiled at the fat lady and she smiled back with her forked tongue flickering between her teeth. They paused at that, forked tongues were not normal. 'What is she, Orochimaru?'. Naruto thought while getting ready for anything and noticing Percy was still processing. He rolled his eyes at that.

Before either of them could really do anything, the Chihuahua and the fox jumped off the fat lady. The mini dog began to bark at Percy while the fox was growling at Naruto.

"Now, now, my darlings," the lady said. "Does this look like a good time? We have all these nice people here."

"Look, a doggie and a fox!" the little boy shouted while his parent pulled him back.

The two animal bared their teeth at the demi-god duo and the lady sighed. "Alright my children, if you insist."

"Uh….did you just call the chihuahua and the fox your children?" Percy asked and Naruto knew something was wrong with this lady.

"Chimera, dear," the fat lady corrected. "Not a Chihuahua. It's an easy mistake to make, but yes the chimera and the fox are my children." She rolled up her denim sleeves, revealing that the skin of her arms was scaly and green. When she smiled, they saw that her teeth were fangs. The pupils of her eyes were sideways slits, like a reptile's.

'So this is Echidna, the mother of all Monsters, great just fucken great. Better kill them fast since we don't have much time left,' thought Naruto as he he reached for his katana and unsheathe it and getting ready to fight.

The Chihuahua barked louder, and with each bark, it grew. First to the size of a Doberman, then to a lion. The bark became a roar. While that was happening to the seemingly small and harmless Chihuahua, the fox's growls became louder and louder as it grew to a gigantic size, like a large bull. It's red fur became spiky as if it was on end from is anger. The fox looked like very feral and dangerous.

The little boy screamed. His parents pulled him back toward the exit, straight into the park ranger, who stood, paralyzed, gaping at the monsters.

The Chimera was so tall its back rubbed against the roof. It had the head of a lion with a blood-caked mane, the body and hooves of a giant goat, and a serpent for a tail, a ten-foot-long diamondback growing right out of its shaggy behind. The rhinestone dog collar still hung around its neck, and the plate-sized dog tag was now easy to read: CHIMERA—RABID, FIREBREATHING, POISONOUS—IF FOUND, PLEASE CALL TARTARUS—EXT. 954.

The same could be said for the Fox. It had fiery red fur that looked like it could pop a balloon, very sharp teeth that had its fill of flesh, and a long and sharp claws on each paw that did not look friendly. It also had a collar that said: TEUMESSIAN FOX—FERAL, DANGERUOUS, VERY FAST, AND EATS CHILDREN—IF FOUND, PLEASE CALL TARTARUS-EXT. 954.

"Why are you here," asked Naruto.

"The son of Posideon has angered Zeus and decided to sent me to test you young heroes but enough talk, shall we fight."

The Fox decided to attack first and aim to strike Naruto but he got into a stance and enhanced his katana with wind chakra. As the fox got close enough, Naruto slash at the fox vertically and then said"Futon(Wind Release): Slash of the Dragon" as the Fox was other split in half vertically and turned to gold-dust and leaving a fox fur behind.

Before Echidna could say anything, Naruto performed a quick hand sign and performed, "Ranton(Storm Release): Laser Circus" as Naruto fired beams of lightning which flows like water at her, hitting her and knocking her out of the Arch. Naruto then looked at Percy.

"Percy, you deal with the Chimera and I'll finish off Echidna OK," said Naruto and Percy nodded. And Naruto decided to run and jump down the arch to get to Echidna.

As Naruto dive bomb down until he reached the falling Echidna and when he reached her, he slash her multiple times and then used her as a landing cushions to reduce the impact and landed on the ground creating a large crater. Naruto got and left unscratched while Echidna looks like she was broken in half.

Naruto decided to walk away but then sensed that she was still alive. As he turned around, he saw her getting back up like it was nothing and she looked at him and then said.

"I will not be defeated by a mortal. I don't care if your Artemis and Minato's brat but I will kill right now boy," said an angered Echidna as she rushed towards him out of anger and blocking all sense of reason.

Naruto just sighed and created a shadow clone. The shadow clone performed a hand sign and then said "Suiton(Water Release): Water Formation Wall" as Naruto blew out fence of water forming a large of water where it hit Echidna and trapped her in the torrent of water. As she struggled to get out of the wall due to jutsu ability where wall's strength and resistance change following the quantity of chakra poured down into the water and Naruto was using a decient amount.

The original Naruto formed a Rasengan on his hand and went towards Echidna and shoved the Rasengan to her head, knocking her back a good distance and when is was clear, there was nothing left of her but gold-dust and a snake skin coat behind, Naruto went up to it and sealed it in a scroll.

'Finally the bitch is dead' thought Naruto as he unsheathe his katana.

He then saw Percy falling down from the Arch and was about to try and catch but then realized that he was falling into a river and since he is the Son of Posideon, he would be fine and then walked to his direction.

Percy climbed out of the river on to a floating McDonalds just saw Naruto, leaning against the wall. He was about call leccture Percy, then they heard, "Mommy looked, that boy walked out of the water!

"That's nice dear." A mom told her child.

"But they are not even wet!"

A news lady was talking for the camera: "Probably not a terrorist attack, we're told, but it's still very early in the investigation. The damage, as you can see, is very serious, especially since an underwater bomb went off, making the water reach as high as the Arch, dosing out most of the flames. We're trying to get to some of the survivors, to question them about eyewitness reports of two people falling from the Arch."

At the word, survivor, Percy sighed in relief, but he wondered what they meant by underwater bomb, he was under water and none of that happened! "Ah Percy, that one was my fault, I sent a water dragon up to dose out the flames." Percy looked at his blond friend before turning back to listen to another reporter.

"... two adolescent boys," another reporter was saying. "Channel Five has learned that surveillance cameras show them going wild on the observation deck, somehow setting off this freak explosion. Hard to believe, John, but that's what we're hearing. Again, no confirmed fatalities ..."

"Uh…we should get going." Naruto replied with a sweat drop.

"Right." Percy said as they kept their heads down.

They had almost lost hope in finding their friends until they heard Grover bleat out, "Per-ccy! Naruto!" Percy got tackled by his goat like friend while Annabeth ran up and hugged the blond first and then Percy when the goat boy got off.

She put on an angry look and yelled, "We can't leave you two alone for five minutes! What the hell happened?"

"I sort of fell." Percy shrugged nervously.

"Percy! Six hundred and thirty feet?" She said exasperated. "And what about you Naruto?"

"I fought the bitch of all monsters and dive down with her and used her as a cushion landing then killing her off," Naruto said while his friend just gawked at him as he showed of the shoes.

Behind them, a cop shouted, "Giveaway!" The crowd parted, and a couple of paramedics hustled out, rolling a woman on a stretcher. Percy recognized her immediately as the mother of the little boy who'd been on the observation deck. She was saying, "And then this huge dog, this huge fire-breathing Chihuahua—"

"Okay, ma'am," the paramedic said. "Just calm down. Your family is fine. The medication is starting to kick in."

"I'm not crazy!" she shouted to the group and then she layed eyes on Percy and pointed at him, "There they are! It's the boy!"

Percy paled and with the help of Naruto dragged Annabeth and Grover away, not wanting to be the center of attention.

"What's going on?" Annabeth demanded. "Was she talking about the Chihuahua on the elevator?"

"Oh yeah….that was no Chihuahua. That was the Chimera that bit Percy, who is somehow all better." Naruto explained while looking at Percy.

"Uh…water heals me?" Percy guessed with a shrug.

"Right." Naruto said sounding skeptical. "I had to fight a baby fox, who was not actually a baby!" Annabeth and Grover looked at the like they were crazy, so the boys decided to explain in detail. Percy told them about the Chimera, Echidna, diving towards Echidna, the water lady of the message and Naruto told them about killing the fox and Echidna.

Before Annabeth could respond, they passed another reporter doing a news break, however they almost froze when he said, "Percy Jackson. That's right, Dan. Channel Twelve has learned that the boy who may have caused this explosion fits the description of a young man wanted by authorities for a serious New Jersey bus accident three days ago. And the boy is believed to be traveling west. For our viewers at home, here is a photo of him."

They quickly ducked under the news van to get away.

"Let's just get the fuck out of here OK," said Naruto and they all nodded.

"Oh by the way Naruto, here's your fox fur," said Percy handing it to Naruto and Naruto took it sealed it fast, and got out of the area fast to avoid attention.

End of Chapter 8

~Omake: Olympians Reacting~

At the throne room of Olympus where all of the gods other then Dionysus and Hades were assembled. Dionysus since he had his responsibilities at the camp and Hades since he was not very welcomed on Olympus, right now Zeus and Poseidon once again arguing over Zeus's bolt.

"I KNOW YOU HAVE IT. JUST GIVE IT BACK. THIS IS JUST BECAUSE MOTHER RHEA LIKED ME BETTER ISN'T IT" Zeus shouted.

"STOP TALKING BULLSHIT LITTLE BROTHER. I DON'T HAVE YOUR FUCKEN TOY."

"IT'S NOT A TOY YOU PIECE OF CRAP"

While they are continue to argue, Hermes then receive a package and it's in his hands right now and got the Gods attention.

"I just remembered I got a package for Olympus earlier" he said.

"It's from Poseidon's son" he said as he unsealed the box and opened it wide.

"Eww" he said as he pulled the head of Medusa out of the box and showed it to the other gods. "I'm guessing he is not too happy with us."

"HE DARES INSULT US LIKE THIS" Zeus stormed while Poseidon rolled his eyes.

"Can you blame him? Anyone who was attacked by the Furies and the Gorgon sisters would be a little angry. He just lost his temper that's all" Poseidon said with a few of the others agreeing. They were willing to let this go if he actually managed to get the bolt since it would stop Zeus from being so bipolar all the time.

"Sent in Echidna to go test the son of the sea scum," said Zues with authority.

Before anyone could say anything, Dinoysus appeared at the throne room.

"Hey Artemis, guess what I found out about your son."

"What?"

"Your son is a pervert," said Dinoysus.

"WHAT?! YOUR LYING!" shouted Artemis.

"Then can you explain this," said Dinoysus with a grin as he revealed the Icha Icha Paradise book in front of her. "It also says in here property of Naruto Uzumaki."

Then Artemis came in front of him and scratch the book from him and read the where it says it belongs to Naruto and when she realized that Naruto was a pervert she took immediate action and rip the book apart and got the council to laugh at her or scared of her but one thing for sure all the perverted Gods including Apollo and Ares and maybe Zeus for being a fan of Icha Icha.

"When I get my hands on that boy, there's not a place in heaven or earth he will escape my fury," said Artemis with her fist raised surrounded by a dark aura and what seems to be a demon appear behind her and got everyone scared shitless and felt sorry for Naruto including the goddesses.

~With Naruto and the Group~

As Naruto was still keeping guard all night on the tree, he suddenly feels a shiver on his spine.

"Why do I feel like when next time I see mum, I gonna be in big trouble."

End of Omake
