The Mangekyō Sharingan (万華鏡写輪眼, Mangekyō Sharingan; Literally meaning "Kaleidoscope Copy Wheel Eye") is a heightened form of Sharingan. The Mangekyō Sharingan gives the user access to powerful and forbidden techniques. The Mangekyō Sharingan is distinguished from a normal Sharingan through its appearance, which changes the form of the tomoe seal. Unlike in the case of the Sharingan, the appearance of the Mangekyō Sharingan differs from user to user; Kakashi Hatake's and Itachi Uchiha's both resemble pinwheels, Madara Uchiha's and his brother, Izuna's look more like a detailed form of the basic three-tomoe Sharingan, and Sasuke Uchiha's looks like a star.

To acquire the Mangekyō Sharingan, someone close to a Sharingan user must die and the emotion of the loss is responsible for its unlocking. To expedite this occurrence, most Uchiha throughout history have killed their closest friends or family members in order to meet this criteria,^[1] though, how Kakashi gained his Mangekyō Sharingan has yet to be explained. (It is interesting to note that in order to obtain the Mangekyō Sharingan, one must feel the emotion of losing a friend, the act of killing them or watching them die alone will not activate it. This is seen with Sasuke and his Mangekyō.)

Over time, use of the Mangekyō Sharingan deteriorates the user's eyesight to the point of blindness. Only by taking and transplanting the eyes of one's sibling (who also wields the Mangekyō Sharingan) can the vision be restored, a process that results in the creation of the Eternal Mangekyō Sharingan (永遠の万華鏡写輪眼, Eien no Mangekyō Sharingan). Not only does this process restore one's eyesight, but it also gives the person greater power. There are only three known living shinobi left who possess the Mangekyō Sharingan: Kakashi Hatake, Madara Uchiha, and Sasuke Uchiha.

Mangekyō Sharingan Variations

Itachi Uchiha

Itachi Uchiha gained the Mangekyō Sharingan by killing his best friend, Shisui. With the Mangekyō Sharingan, Itachi was able to use at least three (and the most, as of yet) of the most powerful jutsu. The first was Tsukuyomi, an extremely powerful genjutsu that allowed him to torture opponents for what seemed like days in a matter of moments. The second technique was Amaterasu, a substantially potent ninjutsu, which creates virtually-inextinguishable black flames at the user's focal point that continue to burn until the target is reduced to ash. The last of these techniques was Susanoo, which allowed Itachi to summon a massive ethereal warrior. This entity fights on behalf of Itachi and shields him from all attacks, rendering Itachi essentially invincible.

All of these techniques use massive amounts of Itachi's chakra and, in addition to damaging his eyesight, put a great deal of strain in his body. During his final battle against Sasuke, Itachi's eyes were even shown bleeding after using the Mangekyō. He also told his brother that he wanted to take his eyes so that he can restore his eyesight and gain more power. During the resulting battle, Zetsu noted that Itachi's "Left Mangekyō" possessed the Tsukuyomi, while the "Right Mangekyō" possessed the Amaterasu.

Kakashi Hatake

Kakashi Hatake developed his own Mangekyō Sharingan during the time-skip. With his Mangekyō Sharingan, Kakashi mastered a technique that creates a localized inter-dimensional space-time ninjutsu called Kamui, allowing him to target any person and/or object and send it to another dimension. The attack requires considerable effort to aim precisely and appeared to leave Kakashi's chakra significantly drained; He collapses after using the technique three times even at full strength in a single day. How he awakened his Mangekyō Sharingan remains unknown, as he stated that everyone close to him was dead.

Madara Uchiha

Madara Uchiha is the first Uchiha to gain the Mangekyō Sharingan. His Mangekyō took the form of a ring with three circular holes in it. He eventually grew blind from overusing it, and only by taking his younger brother Izuna's eyes did he regain his sight. This also gave him an "Eternal" Mangekyō Sharingan that gave him great power. His Eternal Mangekyō Sharingan looks identical in appearance to Madara's first Mangekyō combined with Izuna's Mangekyō.

Madara, posing as Tobi, has shown using an unnamed space/time ninjutsu which makes him nearly invulnerable and allows him to teleport to different places at will very quickly, but it's unclear if this is a result of his Mangekyō Sharingan. He may likely also be able to put out the so-called inextinguishable flames of Amaterasu quite easily due to the fact he was unharmed when Sasuke used this technique on him.

In the past, Madara was able to use his Mangekyō Sharingan to control the Nine-Tailed Demon Fox like a pet. However, it has yet to be shown in the present.

Izuna Uchiha

Izuna Uchiha acquired his Mangekyō Sharingan soon after Madara did. His took the appearance of three bars stretching out of his pupil. Madara later took Izuna's eyes to regain his lost vision. In Madara's story, however, Izuna volunteered to give him his eyes for the clan's sake.

Sasuke Uchiha

Sasuke Uchiha awakened his Mangekyō Sharingan after the death of his older brother, Itachi. Sasuke's Mangekyō takes the appearance of a six-sided star almost resembling the current atomic model. Unlike other Sharingan, which have a black design and red background, Sasuke's Mangekyō is the first one that is shown to have a red design and a black background.

The first ability Sasuke has displayed using the Mangekyō is Amaterasu, which Itachi implanted within his eyes before his death. When Sasuke first used it unintentionally against Madara, his eyes take the appearance of Itachi's Mangekyō Sharingan. When he later uses it on his own, it takes the form of his own Mangekyō Sharingan. Various characters have implied that his skill with Amaterasu might be greater than Itachi's as he is able to control the flames with his right eye. He suffers from the same drawbacks from using it as Itachi did, as his eye strained to the point of bleeding, as well as his eyesight gradually began to deteriorate. He can also put out Amaterasu.

Sasuke has displayed the ability to use Susanoo, which he can manifest as a mere rib cage or a full form capable of attacking others. Sasuke has also been seen using genjutsu with his Mangekyō Sharingan on two occasions that boast similar effects as Tsukuyomi. As with Itachi's version, they are powerful enough to break down the will of the intended victim, and even cause paralysis.^[2][3] However, they have not been named so it is unclear if they are the same.

Unlike Itachi, Sasuke's Amaterasu (ninjutsu) comes from his left eye, and his genjutsu comes from his right eye, along with his ability to manipulate and extinguish the black flames.
