He is named after the mineral nephrite. Like jadeite, it is a variety of jade.
Sailor Jupiter killed Nephrite early on in the manga. His death was postponed until episode 24 of the anime, though. Yet in that continuity, he was killed by Zoisite’s youma rather than by a hero.
In one of Naoko Takeuchi’s illustrations, Nephrite was romantically paired up with Sailor Jupiter. Takeuchi never had the chance to explore the idea of Princess Serenity’s four guardian Sailor Senshi being involved with the Shitennou in the manga. While the first anime and the live-action adaptation both excluded the Sailor Senshi/Shitennou couplings, they were included in Sailor Moon Crystal. In what was likely an unrelated moment, an image of the planet Jupiter appeared when Nephrite created his Black Crystal in episode 23.
Nephrite was the first villain in the anime to be redeemed.
Nephrite and Zoisite were the only two members of the Shitennou to have signature attacks with vocal calls. In episode 23, Nephrite used a technique called Starlight Attack.
Unlike his peers, Nephrite adopted a human alias and persona that lasted for more than one episode. He went by the name of Masato Sanjouin (三条院正人). Broken down, the characters in his names respectively translate to: “San” (三; three), “jou” (条; article), “in” (院; institution), “Masa” (正; real), and “to” (人; person).
Nephrite bled green blood in episode 24. After Sailor Venus injured Zoisite and Kunzite’s hands in episode 33, those two were shown to have red blood.
As he crossed paths with Mamoru in episode 18 at the museum, Nephrite had a déjà vu moment where he mistook Chiba for someone else. This could have been a reference to the manga subplot where the Shitennou were once Prince Endymion’s friends and protectors in the past. The concept was otherwise never brought up in the anime.
Masato drove a Ferrari Testarossa 512 TR.
In episode 44, Nephrite appeared along with the rest of the Shitennou in a flashback. However, he did not speak.

In Greek mythology, Endymion was the human that the moon goddess Selene fell in love with.
The unofficial moniker “Dark (Prince) Endymion” is used by fans to help differentiate between the good and evil forms of Endymion throughout the Dark Kingdom arc. In the first anime, he is referred to by everyone as either “(Prince) Endymion” or “Tuxedo Mask.” Under Queen Metalia’s influence in the manga as well as in Sailor Moon Crystal, Mamoru was called “Endou.”
Endymion disliked Kunzite’s habit of involving innocents in his schemes.
While Sailor Moon did save Endymion in episode 46, he succumbed to his injuries and died. His body, much like everyone else’s at D Point, was later consumed by the power of the Silver Crystal. However, he was revived without any residual effects from being controlled by the Dark Kingdom.
