For countless generations, the accursed Uchiha Clan was heralded for their usage of the sharingan. In modern times, many clansmen have undergone a significant transformation powered by distress to achieve an alternate form of the eye, feared as the Mangekyō Sharingan. However, as it would turn out, the crimson eyes would transform yet again, taking the form of a rippled magenta eye, which has since come to be known as the Rinnegan. Fate would see to the eyes for the fifth and final time, accomplishing the form of the Tenshōgan.
