sharingan
Eye
No, Sasuke has now obtained the Eternal Mangekyo Sharingan, by transplanting his dead brother Itachi's eyes. One ability of the Eternal form is that the user will never suffer blindness from overuse.
Mangekyou Sharingan is the best form of sharingan there is.Mangekyou means "Kaleidoscope"Sharingan means "Copy Wheel Eye"It comes with three new Doujutsu (Eye Techmiques):Tsukuyomi (Genjutsu), Amaterasu (Ninjutsu), and Susanoo (Unknown). Each time the user preforms a jutsu his/her vision is is clouded. He/she will eventually go blind. http://naruto.wikia.com/wiki/Mangekyou_Sharingan
Danzo only has 1 sharingan eye on his right side also he has some kind of special arm (his right arm also) his sharingan first shows on naruto shippuden episode 199 but it only shows for a few sec when he kills these assassins with his eye.
Well, Danzo can have sharingan by having absorbed uchiha shisui's color into his right side of the body. Obito did this to Kakashi when his eye was badly damaged. He put one sharingan eye into his damaged eye. Since Kakashi is not a member of the Uchiha clan, he cannot deactivate his sharingan eye. Because of this, he usually keeps it covered with his mask to conserve chakra.
that's just a happenstance, he has that cloth to cover his sharingan eye.
Kakashi has the sharingan eye because his teammate, Obito Uchiha, was dying, and his dying wish was that Kakashi took his sharingan eye, because Kakashi had lost his eye trying to save Rin, (his other teammate) and so, Rin put Obito's eye (don't puke) in Kakashi's empty socket. And that is why Kakashi Hatake has a Sharingan eye, even though, he is not in the Uchiha clan.
Kakashi did not start out with the sharingan he got it from his friend in his childhood after his eye was cut in battle.
sharingan
yes in book 27 it tells the story of how he got it
No. Sharingan is a fictional ability from the manga, Naruto. It's just a special type of eye technique that the creators of the series gave to the Uchiha clan.
In the manga, Madara implanted Itachi's Mangekyo Sharingan into Sasuke's almost blind eyes. Therefore, the two Mangekyo Sharingan create Eternal Mangekyo Sharingan, restoring Sasuke's vision and preventing all future damage to his eye by using Eternal Mangekyo Sharingan. His Eternal Mangekyo Sharingan is yet to be seen.
You cant. Sharingan isn't real. You can buy Sharingan contact lenses, but theyre very expensive. There is no other way.
Sharingan is not a jutsu. It is a kekkai genkkai or blood trait, like the byakugan. It a secret ablity only members of the Uchiha clan(sasuke and itachi's clan) has. The jutsus that can be performed using a sharingan are a kind of 'doujutsu' (eye techniques), along with byakugan and rinnegan techniques.
Tobi is not Madara Uchiha. He is Obito Uchiha, whose right eye is his original Mangekyo Sharingan eye. His other eye is the eternal one, considering he can evolve it to the Rinnegan form, it's most likely to be one of Madara's.
Tobi wields the Makengo Sharingan.
