Well… crossover fanfics have always been my favourite so I decided to write a crossover of Percy Jackson and Avatar: The Last Airbender for my first ever FANFIC! Yes, that's right. I'm a newbie at writing here… so please REVIEW! COMENTS, TIPS AND SUGGESTIONS ARE HIGHLY WELCOME!

POSITIVE AND NEGATIVE REVIEWS ARE VERY MUCH WELCOME!

PS: I DO NOT OWN PERCY JACKSON, HEROES OF OLYMPUS AND AVATAR THE LAST AIRBENDER

CHAPTER I: PERCY POV

Percy wasn't sure about what the four strange people doing inside his bunk, but he was sure that they weren't there to sing him to sleep and tell him bedtime stories. And he certainly hoped they weren't there to kill him.

A few minutes ago, Percy was just sitting at the white bed in his bunk at the Argo II. He was thinking about the seemingly impossible quest ahead of him and his friends and how they were gonna accomplish it. Then suddenly two weird girls and three even weirder boys appeared out of nowhere.

As far as Percy knows, Leo had installed some state-of-the-art burglar/monster alarm system In the Argo II. Seeing that no such alarm had gone off, these strange kids probably didn't enter the ship by any normal way.

Keep your guard up Percy. Remember, expect the unexpected.

Percy checked his pocket for his sword, Riptide. He wasn't sure if these kids are monsters or not, but he wanted to be able to defend himself, just in case. Percy was snapped out of his thoughts when the girl who looked disturbingly very much like Piper spoke in a shaky voice.

"Um… hello?" the girl with the brown hair asked. Percy looked around the room, startled.

Right then, a harsh voice interrupted before Percy could answer.

"Hey you Polka-dots! You better tell us where we are RIGHT NOW or I'll be extremely angry. And don't you lie to me, because I will know if you do." The little girl with black hair demanded angrily. She fisted her hands to prove her point.

Percy noticed the girl's eyes and assumed that she was blind. I wonder how she knew that I'm sitting on the bed, Percy wondered.

Out of the corner of his eye, he saw the kid with the arrows give himself a face-palm. The others just gave exasperated sighs. One of them mumbled something like, "why, Toph?"

Percy, being a powerful demigod and all wasn't shaken by the newcomer's threat. But he was clearly confused by the nickname. Polka-dots hmmm…. Oh I get it. She means my blue polka-dot pajamas. Percy frowned, clearly embarrassed.

"Don't you just go frowning there, answer me!" the girl demanded again.

Percy took out Riptide out of his pocket. The newcomers gasped when they saw the glittering bronze sword in Percy's hand.

"Whoah… n-nice s-sword you –got there d-dude!" The boy in the Asian blue clothes said, sounding scared instead of surprised.

Percy spoke for the first time. "I don't know who are you guys but be informed that I will stop at nothing to keep my friends safe, even if it includes fighting all of you by myself! And if you don't mind me saying, why would I answer your questions when you're the one who trespassed in my room the first place! I think it's right that YOU answer my question first. So… WHO THE HADES ARE YOU AND WHAT DO YOU WANT!"

ABOUT 30 MINUTES EARLIER KATARA POV

Yup…life's good. Katara thought as she loaded their food and supplies on Appa's back. It's been almost three months since Aang defeated the Firelord and once again restored balance to the world. She and her friends- Aang, Toph, Zuko- and her brother –Sokka- are goung to their first camping trip after the war. She was excited because she didn't get to spend enough time with Aang and the rest of the Gaang, as they liked to call themselves, since they were all busy with keeping peace and order in the world.

15 MINUTES LATER

All was packed and ready to go. As far as Katara could tell, she wasn't the only one who was excited to go on this trip. Toph was practically bouncing with excitement, even though Katara knew Toph hated air travel, since she couldn't "see" at all.

"Yip, yip!" Aang shouted with glee and up the gang flew.

About after 5 minutes in the air, the Gaang sensed that something was terribly wrong with the weather. Huge blasts of wind was trying to keep them off-course. Aang was already trying his best to control the wind around them, but it was hopeless.

"Uh oh guys, I think a storm is coming." Katara said nervously.

"You think?" Toph replied sarcastically and rolled her eyes.

"This is no time to joke around Toph. This must be the worst storm I have ever seen in all of my lives! I better get us to safety." Aang replied, worry clear in his voice.

Katara could see that Aang was putting all his effort into trying to get Appa to fly down, but all of his efforts were futile. And just when Katara thought that things couldn't get worse, they plummeted downward, falling at incredible speeds.

The last thing she saw was a big owl, flapping its gigantic wings vigoriously, exactly like the one they encountered at the library in the desert. And before Katara knew it, everything went black and she passed out.
