Mangekyou Sharingan

Mangekyou Sharingan is a powerful doujutsu and evolution of the Sharingan. This doujutsu can be obtained by reaching 3 Tomoe Sharingan and killing a member of the user's clan. Also, the user's vision becomes darker each time the Mangekyou Sharingan is used, but the user can't become completely blind.

Jutsus
When the user unlocks the Mangekyou Sharingan, a path of an existent Uchiha is chosen. Mangekyou Jutsus deal damage to the own user, but the damage turns lower after evolving to another stage, and the user can only use a certain amount of Mangekyou Jutsus per day.

Stages

 * Stage 1: In this stage, the user can use only 1 Mangekyou Jutsu per day, and the moves do normal damage to the user.
 * Stage 2: In this stage, the user can use 2 Mangekyou Jutsus per day, and the moves do less damage to the user.
 * Stage 3: In this stage, the user can use 3 Mangekyou Jutsus per day, the moves do even less damage to the user, and evolving to Eternal Mangekyou Sharingan is unlocked.

Evolution
The Mangekyou Sharingan can evolve to the Eternal Mangekyou Sharingan by killing another Mangekyou Sharingan user. By evolving to the Eternal Mangekyou Sharingan, the user's vision turns back to normal.
