Rinnegan

It is the Uchiha’s kekkei tōta, which grants a good number of abilities to the person who develops them fully, it is one of the four great dōjutsus and is known as “The Samsara Eyes”. The Rinnegan has three levels of evolution, with the third level being the strongest.

Abilities
In the first level the user retains all the abilities from the Sharingan, while gaining the ability to sync with the Gedo Statue, becoming able to summon it, manipulate gravity and can put anyone who see their eyes directly in a genjutsu.

With the second level the user receives three tomoes to their eyes, allowing them to destroy the soul of anyone with less chakra reserves than them if the enemy is touched in the head, also the user can revive one person in exchange of its own life.

When the third level is reached the user gets three more tomoes to their eyes, totalizing six and can activate the Infinite Tsukuyomi if the requirements are met, being immune to it as well and they also can open portals to other dimensions or planets through the universe.

Predecessor
The dōjutsu is awakened if any bearer of a mature Sharingan receives pure chakra in their system or if they have Uchiha and Senju/Uzumaki blood, but if the latter condition is fulfilled the user cannot evolve the Rinnegan beyond the first level.
