Toneri Ōtsutsuki is a descendant of Hamura Ōtsutsuki and the sole survivor of the Ōtsutsuki clan's branch family on the Moon. 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. Toneri is a powerful individual, his prowess being such that he can combat the likes of Naruto Uzumaki while utilizing his senjutsu-enhanced Nine-Tails Chakra Mode. Toneri has enough medical knowledge to transplant eyes and treat severe injuries. Similar to his ancestor Hamura, Toneri is able to communicate with others from afar, accomplishing this by entering their dreams.
