Kinshiki Ōtsutsuki was a major antagonist in the 2015 anime film Boruto: Naruto the Movie. He was the foster father and servant to Momoshiki Ōtsutsuki and helped him go after Naruto Uzumaki during the film. He also appears in the anime and manga Boruto: Naruto Next Generations.
He was voiced by Hiroki Yasumoto in the Japanese version, and Wally Wingert in the English dubbed version.
Much like other members of the Ōtsutsuki clan, Kinshiki had pale skin and light colored blue-tinted hair. He was a tall burly man who was big enough to allow Momoshiki to sit on his shoulder. He wore white robes and pants. In some of his appearances, the robes would cover a portion of his face. He also had large hands and as a member of the Ōtsutsuki clan, he had Byakugan eyes.
Kinshiki Ōtsutsuki, was a loyal servant to his foster son, Momoshiki. He was willing to protect Momoshiki from danger during his battle against his enemies shortly before turning into a chakra pill from Momoshiki. Kinshiki was also a fierce fighter who never let up on his enemies in battle like Sasuke Uchiha and took them as serious threats. Like Momoshiki, he did not care about the damage Momoshiki would have done to the Leaf Village if he had unleashed the attack.
Kinshiki had superhuman strength and durability as he was able to clash with Sasuke multiple times and knock him back multiple times. He was able to sustain attacks from Sasuke without feeling any significant pain. Kinshiki's superhuman strength was great enough that he was able to knock down a god tree with one swing from his chakra blade.
Kinshiki also had the ability to use chakra to make solid weapons like blades in his battles. With his superhuman strength, the use of the blades could cause a lot of damage and harm to others.
In the past, Kinshiki met Momoshiki and had him as a foster son. Kaguya Ōtsutsuki became aware of Momoshiki and Kinshiki and decided to create the White Zetsu Army as a way to fight against them one day when they decide to try and take her chakra.
