Chapter Six: Kaleidoscope Copy Wheel Eye
"Well Naruto, the Sharingan…"
"…is the Uchiha clan's Kekkei Genkai and their doujutsu." The Kyuubi explained, "Basically meaning 'Copy Wheel Eye.' The most basic abilities of the bloodline allows for the user to experience everything slower, and be able to memorize techniques, whether they are ninjutsu, taijutsu or genjutsu by copying the hand seals required, as well as a basic understanding of where the chakra is being flowed to."
"So, this bloodline allows you to technically steal jutsu's and taijutsu just by watching them do it?" Naruto asked, and the Kyuubi nodded. Naruto just looked disgusted, "Well, I think that's a waste of the jutsu creator's time if it can be copied. No wonder the Uchiha clan in the village have a superiority complex… They're like power hungry pigs…" he said as he finished his rant.
"As the Sharingan evolves, which is determined by how many tomoes are present, one being the lowest, and three being the highest," Kyuubi added, "It also allows you to somehow predict the movement of enemies, and increases your perception, allowing you to see the smallest of muscle twitches, or very small movements. Along with this, you are able to see through almost any genjutsu, but it is not as effective as the Byakugan."
"Hmm… that's quite useful, because of you my chakra control will be shitty for a long time due to my reserves, and I won't be able to dispel genjutsu for a while." Naruto thought out loud. "Anything else?"
"Yes, there is one more thing." Kyuubi paused, "This is a weaker version of Seishin-Tekina Kontororu. It allows you to give the target suggestions and thoughts purely by eye-contact. The more advanced users of this technique can even control boss summons with enough chakra."
"That's quite useful." Naruto responded, "Now can you tell more more about my Mangekyo?" Naruto asked hopefully.
"Ahh, the 'Kaleidoscope Copy Wheel Eye,' is the advanced version of the Sharingan. This is often obtained by killing your closest friends, and the guilt followed after causes the eye to transform." Kyuubi responded, noticing the scowling face of Naruto as he said 'killing your closest friend'
"Gah… that seems more like a curse then a blessing. I'm guessing for a person to do that, must mean the power of this eye is very powerful." Naruto asked, curiosity glinting in his eyes.
"Yes Naruto, there are four techniques unique to only this eye. Amaterasu, Kamui, Susanoo, and Tsukuyomi." The Kyuubi said.
"So… how did I gain mine? I mean I never killed any of my friends, not that I had any." Naruto asked.
"Your pain and hardships as well as my own influence helped develop the eye." said the Kyuubi before yawning. "Now now, I am tired, and you should wake up sleepyhead." she said as she giggled at the pout on his face. Everything went black as he was pushed out of his mindscape.
Naruto yawned, as he prepared for the busy day ahead…
Naruto Information Center: Doujutsu
In the world of Shinobi, there are currently three known doujutsus that exist. Each having their own weaknesses and advantages. Doujutsu means "Eye Techniques."
Byakugan
The Byakugan is the doujutsu of the Hyuuga clan. This doujutsu is activated upon birth and does not have any stages in it's form. The most distinguishing feature of the eye is the colour spectrum of the eye. It is mostly white, surrounded by a transparent colour, ranging from gray to violet. When the doujutsu is activated, veins on the side of the eye enlarge, and the eye gains a circular outline of a pupil. The most prominent ability of the eye is to see in a complete 360 degrees, with a blind spot located at the back of the neck, above the third thoracic vertebra. Along with this ability, they are able to see through objects, making espionage extremely easy, as well as tracking. The third and final ability, is to see the flow of chakra in the pathway system, as well as the 361 tenketsu. Being able to see chakra also devoid's almost all genjutsu's used against them.
Sharingan
The Sharingan is the doujutsu of the Uchiha clan. This, unlike the Byakugan is not activated at birth, requiring a condition of mental or physical stress to activate. Unlike the Byakugan, you cannot know whether they have the eye or not, as it is activated like the Byakugan (Once they have it.) Once it's activated however, it is very easy to tell. The iris turns a crimson red, and tomoes surround the middle, in proportionate sections. The number of tomoes indicate what stage the Sharingan is at. One tomoe are people who have just gained the eye, two tomoes means the user is maturing, while three means the Sharingan is completely matured. The basic abilities when activated include higher perception of the area, able to take in information that the naked eye cannot. They are able to copy techniques from other people by scanning them with the eye when they perform the technique. They are able to perform a hypnosis technique, which suggests certain actions and thoughts to the victim, imitating a "look into the future" action. More experienced users can even control beasts of power, something Madara did to provoke the attack on Konoha.
There is another stage after the fully matured stage, also known as the Mangekyo Sharingan. This is obtained by killing the person who is closest to you, as in a relationship. They must feel the guilt that occurs when you kill them, killing them without remorse or watching them die will not activate it. How Kakashi or Shisui obtained it is unknown as of now. Over use of these techniques will eventually cause blindness. In order to restore their eyesight as well as negate the effects of using the Mangekyo, they must implant the eyes of another member with the Mangekyo, which turns them to a wielder of the Eternal Mangekyo Sharingan. Four techniques are acquired through gaining the Mangekyo. The four of them will be explained in the later chapters, when they happen.
Rinnegan
The Rinnegan is the most mysterious of the three. It is unknown whether it is activated at birth like the Byakugan, or activated from extreme stress, like the Sharingan. The Rinnegan is characterized by a completely purple-hued eye, with multiple concentric rings surrounding the pupil. This eye is know to be able to master the five basic elements, Fire, Wind, Lightning, Earth and Water, as well as the six paths techniques. It is also said that the Rinnegan can see chakra on it's own. The first person to posses such a bloodline was the Sage of Six Paths. Overall this eye is completely a mystery to the five nations.
