Mangekyō Sharingan

The Mangekyō Sharingan (万華鏡写輪眼) is an advanced form of the Sharingan that has only been activated by a handful of people. They are noted to be the "heavenly eyes that see the truth of all of creation without obstruction" (天壌の理を掌握せし瞳).
== Overview ==
A Mangekyō Sharingan is distinguished from a normal Sharingan by its appearance, which changes the form of the tomoe seal. While the exact design differs for each user, they all resemble pinwheels. It is initially awakened by the trauma suffered from witnessing the death of someone close to the user. Uchiha have historically misunderstood this criteria as the user needing to be responsible for the person's death, and for that reason they developed the practice of killing their closest friends in order to gain the Mangekyō Sharingan. Obito's Mangekyō activated immediately after his trauma, whereas, in Naruto Jinraiden, Sasuke's Mangekyō didn't activate until several weeks afterwards.
The Mangekyō Sharingan retains all of the Sharingan's generic abilities. In addition to that, the Mangekyō grants powerful abilities that differ between each eye, though abilities may be similar in nature; both Sasuke and Itachi have access to Amaterasu's flames, though the extent to which they can use them differ. The abilities of a Mangekyō Sharingan may not even be the same for both of a single user's eyes, as Itachi has Amaterasu in one eye and Tsukuyomi in another. As each eye houses the particular dōjutsu techniques, one can only access them if they currently house the said eye, even if they were the originator of the said technique. Once a user awakens the Mangekyō in both eyes, they are able to perform Susanoo, even without either eye. In addition to the unique techniques, the straight tomoe (直巴, choku tomoe) of Madara's and Sasuke's Mangekyō Sharingan grants them greater fluidity in their movements when fighting. Madara was able to sense this form and later deduced that he and Sasuke must be connected by more than blood.
As with any dōjutsu, Mangekyō Sharingan can be transplanted into non-Uchiha, granting them all its abilities albeit with steeper chakra demands. Unlike the standard Sharingan, a transplanted Mangekyō Sharingan can be freely activated or deactivated by non-Uchiha at will. Abilities of a Mangekyō Sharingan can also be programmed to activate under certain circumstances, either within the user's own eyes or in a target of the user's choosing; this programming remains even after death.
Using them comes with a certain sensation that sensors can feel, although it doesn't show which technique is being prepared. Even for true wielders, usage of the Mangekyō Sharingan's abilities can cause a great strain on the user. It drains a considerable amount of chakra when simply activating and maintaining the advanced dōjutsu, and even more through each technique used. Even more, it can cause considerable damage to their being, leaving the body in agonising pain and causing deterioration to their vision until eventually over-usage leaves them blind. Their vision can be restored by transplanting the Mangekyō Sharingan of an Uchiha with strong blood ties — ideally a sibling — thus awakening the so-called Eternal Mangekyō Sharingan 永遠の万華鏡写輪眼. Unlike with other transplants, this second evolution will allow the user to retain their original techniques. Although these eyes merge the designs of the two Uchiha's Mangekyō Sharingan, they're still the eyes of the previous owner and thus react to certain techniques that are aimed at the original owner's Mangekyō Sharingan. Also, they no longer suffer any negative side-effects from using them, even reducing chakra-draining to an unnoticeably minimal level. According to Madara, the Eternal Mangekyō Sharingan is proof an Uchiha has continued to push forward despite experiencing great losses.
The Mangekyō Sharingan also grants its user the ability to read and decode the Uchiha Clan's Stone Tablet. According to Obito, the Mangekyō Sharingan can decode it more than the Sharingan, but less than the Rinnegan.
