Momoshiki Ōtsutsuki

was a descendant of the Ōtsutsuki clan and the main antagonist in Boruto: Naruto the Movie.

Appearance
Momoshiki had 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 had delicate facial features and his eyebrows are cut very short as a symbol of nobility. He dressed 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 with a red colour. He also wore a transparent veil.

After absorbing Kinshiki Ōtsutsuki, Momoshiki's appearance took a drastic change into a bit similar to that of Jirōbō, such as the red skin, and its demonic traits.

Abilities
Using unknown methods, Momoshiki was capable of floating. He could absorb the chakra of his opponents, but was also able to absorb the bodies of his allies, turning them into chakra-filled edibles, which, when eaten, would transform Momoshiki and grant him their abilities. After obtaining Kinshiki's chakra, Momoshiki was granted his ability to form various glowing red weapons. After absorbing nature transformations, Momoshiki obtained the ability to use them simultaneously, but it's unknown whether the power is permanent or not.

Byakugan
Momoshiki wielded 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 wielded the Rinnegan in his palms. With the one in his right hand, he could absorb all kinds of ninjutsu. With the one in is left hand, he could release the ninjutsu he absorbed and fire it. Unlike Hagoromo's and Sasuke's, Momoshiki's Rinnegan wasn't light purple, but red, resembling the Rinne Sharingan. However, after transforming due to absorbing Kinshiki, the Rinnegan in Momoshiki's palms turned purple and he gained an additional purple Rinnegan on his forehead. Like other users of the Rinnegan, he could create Black Receivers as well.

Boruto: Naruto the Movie
Momoshiki made an appearance in the film.

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.
