A/N: Happy anniversary! Yay! It's the 4th anniversary of when I started this story and I can't believe I've gotten this far, I'm so happy.

Also I meant to update much sooner (last Friday) but when I was coming home from my vacation, I got sick and wasn't update to writing fics until Monday... and by then I realized that it was too close to the anniversary so I decided to just wait until today to update. I hope you enjoy the chapter!

Chapter 137: A Literal Sea Monster

The sea monster roared…. Which didn't have the desired effects… Because everyone who heard it roar were wondering how it was possible.

"That thing… how is it able to roar?" asked Kiba.

"Who knows…" said Sakura.

"Naruto are you really going to face that thing?" asked Nami.

"You didn't see my battle with Gaara." Said Naruto, "I'll be fine."

"You didn't see that battle." Said Usopp.

"Naruto just said that…" said Nami with a sweat drop.

"But what's going to happen when those three minutes are up." Said Gaara, "And you're not on land."

"Someone better save me." Said Naruto.

That last bit didn't inspire confidence, of course it made everyone sweat drop.

Naruto took out the rumble ball, "Rumble!" he shouted.

He then transformed into giant sized… the crew could feel the energy as Naruto became giant sized. They knew not to be scared because it was Naruto, not only that but this caused those that didn't witness the fight between him and Gaara to sweat drop. After all this was the first they saw it and it just seems weird that Naruto could become a giant monster.

"So he can transform into a giant monster." Said Isaribi.

"I can as well." Said Gaara.

Isaribi blinked… she had no idea what to say, sure she could turn into a monster… but not one that giant.

Luffy was looking at his younger brother, his eyes were sparkling.

"Oh wow!" he yelled.

"Pay attention!" yelled Amachi who sent out a ball of water at him.

It knocked down Luffy, but he got back up.

"Gum Gum Pistol!" shouted Luffy punching him in the face.

"That's all you got, because that was pathetic." Said Amachi.

"I haven't even started yet!" yelled Luffy.

With Naruto's fight, the giant Kyubi Naruto tackled the giant water monster but that didn't do anything.

"Damn it!" yelled Naruto.

"He is made of water so the trick to find a way to tear him apart." Said Kyubi, "I think."

"Are you unsure?" asked Naruto.

"I really don't know… this isn't a Biju we're fighting… it's something made with SCIENCE!" explained Kyubi.

"Why did you said science like that?" asked Naruto.

"You wouldn't get the joke." Said Kyubi, "Let's just focus on fighting it."

That was when Naruto tackle the monster again, but the monster engulfed him. Fortney he used his tails to escape.

"Naruto I have an idea!" yelled Kyubi, "One of my legendary powers… try it."

"You mean make Tsunamis?" asked Naruto.

"Yes." Said Kyubi.

"I'll think about." Thought Naruto with a big sweat drop.

With Luffy's fight, he was having a hard time. Every hit didn't seem to do anything.

"What is it with you!" yelled Luffy.

Amachi laughed evilly, "You haven't figure it out have you?"

"Figure what out?" asked Luffy.

"My scales are as strong as steal." Laughed Amachi, "Not only that but there's something I haven't shown you yet!"

That was when he suddenly began to shoot needles from his scales. Luffy managed to grab onto a rock and dodge.

"What was that!" yelled Luffy.

"Just one of my abilities given to me by this perfect form." Answered Amachi.

"So cool!" said Luffy with his eyes sparkling.

Isaribi who was trying to watch both fights couldn't help but to sweat drop at Luffy.

"Is that normal…" said Isaribi.

"Yeah… he does that sometimes involving an opponent." Sighed Nami.

"You should pay more attention to my moves!" yelled Amachi sending more spikes.

This time the spikes hit him, Luffy pulled them out.

"These aren't poisonous, they are they?" asked Luffy.

"No… they are not. I studied them." Answered Amachi.

"I see." Said Luffy going in to punch him again.

Isaribi wasn't sure which one to watch… both fights were equally important to her. That is when she felt someone touch her shoulder, she turned and saw it was Gaara.

"What is it?" she asked.

"I wanted to ask you something." Responded Gaara.

"What?" asked Isaribi.

"I wanted to ask you… why did you really save Naruto." Said Gaara.

Isaribi began to think, "Why did I save him?" she thought.

She began to think about to the fight… maybe it was because of Luffy, maybe she saw something in Naruto…

"I honestly don't know." Answered Isaribi.

"Do you think it's because you saw something in Naruto?" asked Gaara.

"Maybe…" answered Isaribi, "Probably."

"Naruto understands what we went through." Said Gaara, "I wouldn't be surprised if that's what you felt."

Isaribi watched the fight and began to think that Gaara was probably right… maybe she did feel like Naruto knew how she felt.

With the Naruto fight he just whacked around the sea monster with his tails.

"Just a reminder, you don't have long." Said Kyubi.

"How am I supposed to fight this thing?" asked Naruto.

"Try the Tsunami thing." Said Kyubi.

"If that won't work… you owe something." thought Naruto.

"Okay… if that don't work, I'll show you another trick." Said Kyubi.

"Deal!" thought Naruto.

Naruto used his tails to create a Tsunami… the water engulfed the sea monster… and did nothing.

"Thank you for agreeing to the deal." Thought Naruto.

"You knew it was a bad idea." Said Kyubi.

"And you thought it was good." Said Naruto.

"Just shut up and I'll teach you that move." Said Kyubi.

With Luffy he began to continue to punch the mad scientist.

"Like I said! I'm as hard as steel. There's no way you can beat me!" yelled Amachi.

That was when Luffy used Gum Gum Spear and tossed him into the rocks. The impact caused a small explosion.

"All right! I did it!" yelled Luffy.

"Don't get your hopes up!" came Amachi's voice from the dust.

The dust cleared, and the fish like man came out unscathed.

"Damn it!" yelled Luffy.

"You can't beat me!" laughed Amachi.

"I have to figure something out." Thought Luffy.

He then aimed an attack for the lower portion of the body… as in hitting the groin. Amachi fell to the ground the ground in pain.

"That was low." Said Amachi

"Doesn't seem like it to me." Laughed Luffy.

Amachi seemed to recover and sent out more spikes at Luffy. As the spikes hit Luffy something came to him.

"That's it." Thought Luffy, "That's how I'll beat him."

With Naruto he closed his eyes…

"Okay, focus your chi into bubbles. Bubbles that come out of the surface of your skin." Said Kyubi.

Naruto began to do that, as both red (which belonged to Kyubi) and blue (which belonged to him) bubbles of chi came out of his skin. The air around the fight was filled with bubbles.

Naruto opened his eyes and saw the bubbles.

"Now compress them!" ordered Kyubi.

"All right." Said Naruto.

He willed them to compressed into a dense purple ball of chi.

"Now eat it." Ordered Kyubi.

"Excuse me?" asked Naruto.

"I said eat it." Said Kyubi, "Trust me, I did this a lot."

Naruto sighed and did so. That was when there was a big explosion in his stomach.

"Oh god." Thought Naruto.

"Now unleash the energy though the mouth." Said Kyubi.

Naruto did so, as this would be like throwing up for him. It felt good to get that out his stomach… however, what was unleashed was massive beam of pure energy. It caused giant gust of wind that blew everyone off their feet, the water became choppy and a large chunk of the island was destroyed to nothingness… but on the plus side the sea monster was destroyed.

"There is no way I'm ever doing that again!" yelled Naruto.

"Fair enough." Said Kyubi.

While Naruto's fight had just ended Luffy's fight was only just beginning.

Next Time: Luffy continues his fight with Amachi as Naruto recovers from the severe ingestion caused by the final attack. However due to the final attack Isaribi sees the papers that Robin took from the lab and discovers something horrifying... what is it? Find out next time.
