Momoshiki Ōtsutsuki

is a mysterious man who seeks Kurama, and is suggested to be from the Ōtsutsuki Clan. He appears in Boruto: Naruto the Movie.

Appearance
Momoshiki has pale skin, blue greyish hair that he wears as a long plait, and rabbit ear-like protrusions, which grow out of the back of his head. He has delicate facial features and his eyebrows are cut very short, as a symbol of nobility. He wears a glove on his left hand, with a hole in the palm for the Rinnegan. He also wears a see-through 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

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.
