Momoshiki Ōtsutsuki

is a mysterious man who seeks Kurama. He appears in Boruto: Naruto the Movie.

Appearance
Momoshiki has pale skin, blue greyish hair in a long ponytail with his bangs parted in a zig-zag pattern, and a pair of wide horns which grow out of the back of his head and curve forward, resembling rabbit ears. He has delicate facial features and his eyebrows are cut very short as a symbol of nobility. He dresses in a traditional white kariginu hunting robe, baggy pants, a pair of tengu-geta, and a single black glove on his left hand, with a hole cut into the palm to display the Rinnegan. He also wears a transparent veil.

Byakugan
Momoshiki wields the Byakugan in both eyes, granting him near 360° vision (with the presumed exception of a small blind spot at the upper thoracic vertebrae), x-ray vision and the ability to see the chakra pathway system amongst other abilities.

Rinnegan
Momoshiki wields the Rinnegan in his palms. It is currently unknown to what extent he can use its abilities.

Boruto: Naruto the Movie
Momoshiki appears as the main antagonist in the movie.

Trivia

 * Similar to how Kaguya was named, Momoshiki's naming convention seems to follow the Japanese folklore motif. It is a reference to Momotarō, while Kinshiki is a reference to Kintarō.
 * On the main poster for Boruto: Naruto the Movie, his Rinnegan are both purple. An official colorisation shows him with a red Rinnegan in his left palm instead.
