The Mangekyo Sharingan or Kaleidoscope Copy Wheel Eye is a heightened form of Sharingan. Mangekyo Sharingan look differ from normal Sharingan through its appearance, which changes the form of the tomoe seal.

Unlike the Sharingan, it has a different appearance between the users, as a kaleidoscope never looks the same when looked through. Kakashi, Itachi, Madara and other Mangekyo Sharingan user have different eyes.

Those who have the potential to obtain it must make a great sacrifice in order to obtain it – according to Itachi, they must kill their closest friend. Itachi, Madara, and his brother apparently do in fact do this to obtain the original version, but Kakashi has noted that everyone he cared about had died long before the start of the series, so how he developed his own variant is unknown. And apparently, the Mangekyo Sharingan can be transferred from person to person, as in the case with Sasuke. The major drawback of the Mangekyo Sharingan is that when it is first activated, it slowly begins to destroy the eyes until the user becomes completely blind. The only way to regain one's eyesight after losing it would be to steal the eyes of a sibling, combining the two Sharingan to create a new, more powerful, and immortal Mangekyo Sharingan which prevents blindness and might grant immortality.

Let see the type of Mangekyo Sharingan which are exist in Naruto's world.

1. Uchiha Itachi Initial Mangekyou (Kaleidoscope) Form

This variation is the Mangekyou (Kaleidoscope) form while not fully changed. Sasuke initially caught a glimpse of this version of Itachi's Mangekyou which differed from his later version.

2. Uchiha Itachi Mangekyou (Kaleidoscope) Form

This is the rare Mangekyou (Kaleidoscope) form which is said to only appear in a few Uchiha members. Uchiha Itachi was able to finally master this form during the period he killed his clan. In this form Itachi is able to use the Amaterasu and Tsukuyomi Doujutsu techniques.

3. Hatake Kakashi Mangekyou (Kaleidoscope) Form

This Mangekyou Sharingan form was revealed by non-Uchiha clan member Hatake Kakashi. Whether this form is due to Kakashi or some inheritance from what Uchiha Obito was capable of is unknown. Using the eye, Kakashi can use a technique which appears to collapse space in around a focus point and transport it to another location.

4. Uchiha Madara Mangekyou (Kaleidoscope) Form

This Mangekyou Sharingan form was attained by Uchiha Madara. After developing the Sharingan, Madara and his younger brother trained against one another and eventually awakened their own version of the Mangekyou. The use of these eyes increased the brothers' strength and allowed them to take over leadership of the clan. Unfortunately the usage of the eyes lead Madara to lose his vision.


5. Madara's Brother's Mangekyou (Kaleidoscope) Form

This Mangekyou Sharingan form was attained by Uchiha Madara's younger brother. After developing the Sharingan, both brothers trained against one another and eventually awakened their own version of the Mangekyou. The use of these eyes increased the brothers' strength and allowed them to take over leadership of the clan.

6. Uchiha Madara's Eternal Mangekyou (Kaleidoscope) Form

Unable to accept being blind, Madara did everything he could to regain his vision. A desperate Madara eventually removed his brother's eyes to use as his own. As a result, Madara awakened a new more powerful set of eyes which allowed him to see the light once again. This new eye form would combine the look of both he and his brother's Mangekyou Sharingan.

7. Uchiha Sasuke's Mangekyou (Kaleidoscope) Form

Itachi sought to protect his younger brother from Uchiha Madara. To that end he used a jutsu to implant his Mangekyou and its techniques into Sasuke. When Sasuke's Mangekyou was initially activated, it resembled the version seen in Itachi. Later Sasuke's Mangekyou took on this form. It is unclear if this is the Eternal Form of Mangekyou, combing the form of Itachi's Mangekyou and that of Sasuke's, or if it is simply Sasuke own singular Mangekyou form alone.
