Tenseigan

The is a powerful dōjutsu utilised by Toneri Ōtsutsuki.

Background
For a thousand years, the descendants of Hamura Ōtsutsuki sealed their eyes within the Tenseigan altar, a giant orb, accumulating tremendous power. If after a millennium they determined that mankind were using their chakra for evil, they would unleash that power upon them.

Due to the sealing away of eyes within his clan, Toneri was born without eyes. As the last survivor of the Ōtsutsuki clan, he concluded that mankind did in fact use chakra for evil purposes, and he was determined to fulfil his clan's thousand year vow and destroy humanity by dropping the moon on the Earth. However, Toneri did not have any eyes since birth and decided to steal Hanabi Hyūga's Byakugan by kidnapping the heiress. After taking her eyes and combining the power of countless generations of sealed Byakugan that were sacrificed by the Ōtsutsuki clan, he awakens the Tenseigan.

Abilities
The Tenseigan is roughly on par with the Rinnegan in terms of strength, and Toneri was said to be as powerful as Madara Uchiha when using it. It also allows the user to use the Tenseigan Chakra Mode.
