(A/N) this is my new fanfic! I don't know how to approach this since I am focusing on Sori's journey, but I am going to give this a shot. It's a naruto-avatar crossover WITHOUT IT BEING NARUTO WHO GETS CROSSED OVER! Since I could barely find any other fanfics without our favorite knucklehead ninja, I decided to give this a try with the one and only itachi. (A/N)

Run, cling to life.

These words now replayed in Itachi's head as he was hurled off a cliff to his death by Zhao. The firebenders had decimated the village, sparing none of the adults. The Uchiha clan was ruined.

Historical Flashback

The Uchiha clan lived in a small village. They payed tribute to the fire nation every year. They were a small clan of 300, but they had a secret: the sharingan. It was an eye that allowed them to copy a bending temporarily. They kept this secret, until a few years ago, Itachi's friend Shisui had his eyes stolen by a man named Zhao. He researched the eyes and found out about their secret. Itachi remembered this all too well. Shisui's death had made him activate the sharingan in both eyes. After that year, the fire nation left them alone until now. Itachi was out talking with his girlfriend Izumi (A/N) She is itachi's would be girlfriend in the show, no joke! (A/N). That was, until Itachi saw movement on his peripheral and tackled himself and Izumi on to the ground.

"ITACHI! WE'RE TOO YOUNG TO HAVE S-" She was cut off as Itachi's hand clapped on her mouth and a giant fire nation rhino leaped over them. Soon, a whole horde had leaped over them, and they were left alone once again in the forest. Izumi sweat dropped as Itachi stood up and activated his sharingan to look at the rhinos.

"The village is in trouble..." Itachi yelled. "I need to save Sasuke!"

"We can't outrun them!" Izumi yelled as they started running over the treetops thanks to their training.

"Explosive tags?" Itachi yelled back. A small pad of said artifact was thrown to him. Itachi set to work, tying them to his kunai knives his village was known for and throwing them at the trees next to the rhino's in the rear.

"Nice!"Izumi yelled as she prepared for her own volley. By then, they were almost at the village where they could here tortured screams and the occasional "MOMMY!"

"Sasuke!" Itachi yelled through the crowd. He recognized his brother being ushered into a hole in the wall mother had made just in case. He saw Fugaku close it and engage the enemy. He didn't last long. Itachi stared in shock as his father, and a few seconds later his mother both fell to their knees impaled by the spears. The rest of the village didn't last long when they saw the matriarch and patriarch leaders of the village dead. The enemy scored the area and rounded up the few survivors, which included at least 10 of the children, Izumi, Sasuke and a few adults.

"What is the meaning if this?" Itachi's aunt yelled. The man who the soldiers called Zhao motioned one of them who swiftly decapitated auntie and the other adults. By now the kids where crying. 3 of the older ones had tried to fight, only to meet the same fate as their parents. Itachi was rooted to the spot. He looked at Zhao with a look of pure hatred.

"DIE!" He said, running directly at him with his kunai. Zhao simply side-stepped and hit Itachi squarely in the chest. He grabbed onto the scruff of Itachi's black shirt.

"Run, cling to life, stupid child."

FLASHBACK END

"Am I going to die?" Itachi questioned himself as he plummeted down the cliff to the salty rocks on the beach. He could hear Sasuke sobbing, and Izumi screaming for him to get up.

"No!" He thought. A new found power entered him. He opened his eyes and saw everything clearly. He took out a kunai and jammed it with all his might into the rock. He slid down but it jarred off. He took another kunai and tried again.

"Only 50 feet left!" Itachi thought frantically. He turned around and jabbed both kunai into the cliff behind him, bringing his legs over his head. For a second, he could see the sand at the bottom of the cliff and then he blacked out.

Hours later

It was the evening now, and the moonlight illuminated the small cliff side beach where Itachi stood with dead eyes. He stared down at a kunai with paper on it which had 3 parts of writing. He recognized Izumi's cursive writing. Itachi, they are taking us to be some sort of black ops with our sharingan. Please, help! They are taking us to the capital. Itachi then saw underneath a small scribbled note in Sasuke's untidy handwriting. Big brother! Don't worry I'll protect Izumi and myself while we're away. Zhao let us write this message so he could laugh at you. By the way: Mppl pvu gps uih fyqmptjwf ubh!

Itachi immediately ripped off the note and threw the kunai, which exploded a few seconds later. He silently thanked Sasuke for that one. He then looked at the last piece of writing, which was in an elegant type. Foolish idiot. Thanks to your death, I know have 10 new sharingan users to brainwash. Good luck. Zhao.

Itachi scowled. Zhao was going to pay. Dearly. He looked at his reflection in the water and almost screamed.

In place of his normal sharingan, was a mangekyou sharingan. The fabled eye had only appeared 3 times in history. Itachi instantly looked into his pocket an took out his scroll about the mangekyou. His grandfather, who's father had it, had given the scroll to him because of his potential. It also had a note. Itachi had always disregarded it, but yet it always drew him to reread it. When you unlock the mangekyou, consult Roku. Itachi frowned. Roku was alive extremely long ago. It was impossible that he was still alive. In fact, the avatar hadn't been alive in nearly 100 years. But this sent a trigger off in his mind. He decided to look over the air temples, just in case the avatar was their. Moving on, Itachi stared at the 5 techniques that were said to be unlocked with each of the 5 mangekyou sharingan stages.

The first was amaterasu, which Itachi assumed he had due to it being te first one. It would allow him to look at anything and set it in fire. It could even burn other fire and water. But the side effect was the he couldn't use or see through his right eye for an entire day, and during that entire day, his eye would be bleeding.

The second one was the tsukyomi. It was a technique which created an illusion of a nightmare world for 72 hours to use on a single enemy. The good part was that the torture actually only lasted a second in the real world. The side effect was the same as amaterasu, but with the left eye.

The third one was the kotoamatsukami. It could be used to control someone's actions. Side effect? He could only perform it once every 10 years.

Then there is kamui. When activated, regardless of one's mangekyou pattern, the eye would morph into that of the great Obito, the first one to obtain the mangekyou sharingan. There is no side effect.

The final ability which Itachi seriously doubted he could ever reach was susano'o. It creates a skeletal warrior that defended the user. It can level mountains in a single motion.

Itachi sighed. This was a lot of information to take in. He needed to rest. Then he could read more of the scroll's other parts and walk to the air temple to get clues on the avatar.
