Puppet Reincarnation

As a last resort, Toneri, in his eyeless state, summons countless Byakugan from the disintegrated Energy Vessel and infuses it into himself. The Byakugan seemingly grants him immense power, which is claimed to be capable of bringing about the end of the world. However, the true power of this technique is never shown as Toneri was exposed to sunlight, which affects the chakra in the Byakugan, making the technique highly unstable and impossible to control. The sunlight also caused the technique to go berserk and mutate the user into unstable white mass, similarly to Kaguya in the Ten-Tails' unstable form, with the large mouth protruding from the back.
