I was having thoughts about the Black Moon Clan for ReStart and it ended up in me redesigning them all, so. yeah lmao. Some info below!
I think the biggest change is that the Black Moon Clan doesn't originate from the future - they're all people from Usagi's present time, who managed to travel in time thanks to Death Phantom's powers. He promised them all greatness, fame, money or a combination of each, feeding them lies to keep them under his control. Their earrings give them their powers.
The Four Apparition Sisters are, from youngest to oldest, Kermesite/Kaon, Berthierite/Emika, Calaverite/Kurara and Petzite/Teru. All 4 struggling with making ends meet and sticking together, Wiseman promised them money and stay in exchange for their services, and mostly do his bidding out of obligation. The Inners fight them, but later manage to help them break free from Wiseman's control and return to a normal life. (Their villain names are lifted from the Latin Spanish dub, which simply used the real name of the corresponding gemstone.)
Rubeus/Ryoga and Esmeraude/Elise came under Wiseman for the simple promise of money and fame respectively, but aren't truly into his cause as much as they are into their own goals. Both are in charge of distributing the Droids to the Sisters, before moving to commanding them themselves. Both manage to escape Wiseman and survive, through different means - Esmeraude takes refuge with the Sisters and gets helped by the Senshi, while Rubeus fakes his death, using a Droid copy of him, and simply goes into hiding.
Demande/Daiya and Saphir/Souji are still brothers, orphans, who Wiseman adopted and raised as his own, feeding them lies about being the legitimate heirs of the ancient kingdom of Nemesis, giving them his power. Saphir was always sceptical but accepted the roof over his head and the food on the table, Demande clung to the idea of being important and powerful until the bitter end. Both unfortunately die as pawns of Satoharu, Saphir as he tried to rebel against him and Demande at the hands of Usagi, because. he's still Demande. Saphir is in charge of creating the Droids.
Amatsu Satoharu is the reeincarnation of Sailor Nemesis, heredating her powers but only some of her memories. He managed to summon his Sailor Crystal (the Reflection Crystal), and used his powers initially just for stuff like petty theft and mayhem, before moving into serial killing, using the name of Death Phantom. He managed to escape and live a hidden life, until he started to get dreams, foretelling his death at the hands of a Sailor Senshi under the protection of the Sun and the Moon. He managed to then find people he could promise power in exchange for their service, and started his plan to kill the problem at the source: Tsubasa.
She was smarter than he thought, however, and escaped to the past thanks to Pluto's intervention. He still managed to deliver a strong enough blow to both Usagi and Mamoru, before retreating into the past as well, launching his attack. He is, of course, killed by the present-day Senshi plus Tsubasa/Eclipse, which sends his Sailor Crystal back to the Cauldron for Lia to then be born some years later.
