Meet one of Sailor Moon's scrapped transformations, La Cygne!
- Saban Moon.
Technically, it wasn't by Saban, but this what would happen if Renaissance Atlantic (the co-producers of Mighty Morphin' Power Rangers and a partner of Bandai America) and Toon Makers got the rights to Sailor Moon. It has its own page at Toon Makers’ Sailor Moon. - In liner notes for the manga rereleases, Takeuchi revealed that she had thought of making Ami a cyborg who wants to Become a Real Boy and giving her a Heroic Sacrifice (if this had actually happened, then the Rei Ayanami Expy trope would probably have been titled Sailor Mercury Expy) along with the idea of Makoto being a gang-leader.
- Early plans for a Sailor V spinoff (that evolved into "Sailor Moon") had Sailor V as the team leader with no Usagi present, while her friend Hikaru would be in the "Ami"/Mercury role. The early gang-leader version of Makoto was in the treatment as well, named "Mamoru Chino" (and depicted as a chain-smoker). Rei also appeared, but with the name "Miyabi Yoruno". The girls would be in search of a mysterious princess named Artemis (relation to the cat unknown). This version was to be produced as an OVA, but plans fell through.
- An early advertisement for the Sailor V manga had her with Usagi's hairstyle and a small crown on her head, with the working title being "Pretty Soldier Sailor V".
- Takeuchi also intended to include a character named "Diana the Moon Fairy", a talkative, impertinant, and playful fairy. She was to be found in the ruins of the Moon Kingdom, and would have stuck with Luna (whom she didn't get along with) and Usagi. She was eventually replaced by Queen Serenity, and the name Diana was used for Luna and Artemis's future daughter.
- Also, Tuxedo Mask could have been named "Mysterious 2098 Face". Takeuchi was later stunned she could have come up with such a bizarre but meaningless name.
- During the early creation phases, Takeuchi initially drew each of the girls with individual◊ costumes◊ before choosing the rather uniform versions later used. She admits she doesn't remember creating these costumes at all.
- The Sailor Guardians' hair colors repeatedly changed. Usagi and her mother were once thought to be green-eyed and brunette, then later changed to both being depicted with pink hair. Ikuko retains her pink hair and red eyes in some manga images, whereas the anime went with the brown eyes and blue hair variety. Usagi initially being portrayed with pink hair was first done, as the idea was that pink was her image color, but this was later changed to white.
- Allegedly, back when a live action Sailor Moon movie was in talks in the late 90s, Geena Davis was considered to play Beryl. Fan rumors around the time suggested that Rini was going to be turned into Serena's little sister not her future daughter (which is kind of weird for their parents to gave their daughters similar names, since Rini is a diminutive of Serena) and Amy was going to have normal hair.
- DiC originally considered dubbing up to the first 13 episodes of S, but they were only able to afford to dub the rest of R. However, their considered names for the Outer Guardians did make it on to the early Irwin Canada doll releases, with Haruka being called "Corrinn", Michiru being "Nerissa", and Setsuna being "Celia". Allegedly, DiC would have portrayed "Corrinn" and "Nerissa" as best friends, which would likely mean S would have experienced quite the editing (which it did with Cloverway, although they didn't edit enough at times, making the "cousins" cover-up look rather strange).
- The Mixxzine/Tokyopop version of the manga briefly had Hotaru (who later became the only guardian to retain her original name in the Cloverway dub) named Jenny. It was changed back in later issues.
- When Sailor Stars was being developed, animation director Yoichi Fukano designed a new form for Sailor Moon called "Sailor Moon La Cygne" or "Sailor Moon Swan". The◊ design◊ went away from the standard Sailor Guardian motif, looking like a transition between Sailor Moon and Princess Serenity. Ultimately, though, Naoko Takeuchi's Eternal Sailor Moon design was used.
- Usagi was going to receive her Eternal form by Pegasus while falling to save Chibiusa. It was changed to her transforming to a winged Princess Serenity instead.
- Sailor Cosmos was going to appear in the '90s anime as the sailor form of Chibi Chibi. It eventually became the embodiment of Galaxia's starseed, giving only a glimpse of Cosmos in the final episode.
- Sailor Heavy Metal Papillon was going to appear in the anime version paired with Sailor Tin Nyanko. She was featured in some episode scripts but was scrapped.
- Naoko Takeuchi suggested an eternal update for all the sailor guardians to take place midway during Sailor Stars. She also hoped the season would end with Neo Queen Serenity's coronation.
- The anime would originally feature Usagi as the main lead for 20 episodes. The manga side didn't want the anime to utterly overtake them, so the plan was to give them time to build up everything. However, Toei Animation requested that Ami and Rei be featured in the opening. This caused rumors to start up that there would be more Sailors, thus they had to change gears and introduce the girls earlier.
- Sometime in 2002, Irwin's website added character bios for Chibi Chibi and Princess Kakyuu, hinting at a Canadian-exclusive dub for Sailor Stars being in the works. Unfortunately, this dub was cancelled after Toei declined to renew the worldwide rights for the Sailor Moon anime in 2003. Viz Media would eventually dub Sailor Stars for a 2019 release.
- Between 1995 and 1997, there were rumors about Bandai producing a Sailor Moon game for Nintendo 64. It was ultimately released for the PlayStation in late 2001 as Kids Station: Bishoujo Senshi Sailor Moon World - Chibiusa to Tanoshii Mainichi.
- Naoko Takeuchi initially planned to expand upon the romantic drama by making it that Prince Endymion's four knightly vassals, who were corrupted into Beryl's dark generals, had been in relationships with the Inner Guardians, mirroring the romance between Endymion and Princess Serenity. However, whilst Takeuchi drew an art piece depicting the Princess, Endymion, and the four Sailor Guardian/King of Heaven couples she had planned — Zoisite and Mercury, Jadeite and Mars, Nephrite and Jupiter, Kunzite and Venus — and worked in a reference to Kunzite and Venus' former relationship into the prequel manga Codename: Sailor V, the idea was never explored in the manga itself. Which even led to the 90s anime adaptation famously pairing Zoisite and Kunzite together, and giving Nephrite a tragic relationship with Usagi's friend Naru. Post-manga adaptations would refer to the idea to varying degrees, and it would eventually be canonized on-screen with Sailor Moon Crystal.
