Shoku

Shoku (食) is the synthetic human created by Nisshō to serve as his avatar in particular time periods.

Creation
Created around the same time as his sister Tsuki, Shoku was crafted to act as an agent for time periods and dimensions where Nisshō couldn't directly interact. As the "elder" of the two synthetic humans, Shoku holds his father's Sharingan, and Mangekyō Sharingan, rather than the Byakugan or Tenseigan.

Shoku was awakened and sent into the past to help destabilize the Great Shinobi Nations, and cause anarchy. He was given a similar ability set to fit his augmentations and as a result, is able to stop time with Inyō, travel through time with Time Shift, or steal information using Yin Release: Mind Meld Probing.

Unnamed Dōjutsu
Born from a mutation in his development, this dōjutsu manifested within Shoku's forehead as a "third eye" similarly to that of the Rinne Sharingan, however, this holds no connection to the Rinnegan or the Sharingan, despite Shoku being born with the latter. This newly discovered Dōjutsu seems to allow Shoku to not only, but also Teleport himself in the blink of an eye.
