Toneri Ōtsutsuki

- Toneri's full appearance. - Toneri's wedding attire. 1/2 Toneri is characterised by his pale skin, shaggy white hair, attractive facial features, and six magatama designs tattooed on his collarbones to resemble a necklace. He typically keeps his eyelids closed, as his eyes were ceremoniously removed some time after birth. He later transplanted Hanabi Hyūga's Byakugan into his empty eye sockets, which eventually matured into the Tenseigan; an enhanced version of the Byakugan. After Toneri was defeated, his stolen eyes regressed back into the Byakugan, which were then reclaimed to return to their original owner. Toneri usually dresses in clothing typical of the Ōtsutsuki Clan, consisting of a white, high-collared kimono with a black obi, over which he wears a pale green sash tied at the right shoulder. On the back of his kimono is the Ōtsutsuki Clan branch family emblem of a yellow crest depicting a sun enclosed in a crescent moon. Beneath his robes he wears black fingerless gloves, long black pants, and black shinobi sandals. As a child, he is shown wearing a similar clothing, consisting of a white kimono, pale green sash, and black sandals. During his marriage ceremony, Toneri wore a traditional Ōtsutsuki Clan wedding outfit consisting of a grey high-collared tunic and baggy grey pants with a black obi and black shinobi sandals. Overall, he wears a long black sleeveless robe and a dark navy blue sash, which is draped over his right shoulder. Both the tunic and robe are embroidered in gold, with six golden magatama on the tunic's collar and a yellow Ōtsutsuki branch family emblem on the back of the robe. He also wears a matching black turban and a pair of black wristbands.

Toneri was born into the Ōtsutsuki clan's Branch family, leading to his eyes being sealed within the Energy Vessel at birth; in place of vision, he learned to sense the world around him instead. Growing up with his father on the Moon, Toneri desired human friends, unlike the puppet servants that served his family. On multiple occasions, the two would take travel to Earth to secretly observe the Hyūga Clan in Konohagakure, whom descended from Hamura's direct bloodline. Toneri's father at some point suggested that Toneri should someday marry Hinata Hyūga; the latter whom was heiress of the Hyūga clan at the time. When his father was on his deathbed, he encouraged Toneri to forget about the clan's decree and go to Earth to find friends and comrades, to live for his own sake. After his passing, Toneri thought about his ancestor's wishes, leading to him deciding to stay on the moon isolated as the last surviving member of his clan's branch family, with only the clan's autonomous puppets for company.
