Beam Me Up, Scotty!: One of the biggest jokes from non-fans is how the monsters and bad guy guys have to wait for the Sailor Soldiers to transform when they could just attack them. This was even parodied for a pair of skits on Robot Chicken. However, the characters almost never transformed in front of their opponents. On the rare occasion that it did happen, the show seems to imply it's instantaneous.
Defictionalization:The Sailor V video game the girls played at Motoki's arcade eventually got made, and was included as an extra in the Gameboy Sailor Moon R game. It's also as hard as depicted in the anime, which gives one new respect for Ami and Minako's playing skills.
Executive Meddling: The sudden 180 in tone after the third season is believed to be the result of this trope - there were concerns that the original audience for the show was growing out of Sailor Moon (and thus growing out of buying the toys.) Hence SuperS jettisoned even mentions of the Outer Senshi and the darker and more complex storylines, and refocused the show to spend more time on Chibi-Usa, a younger character who could theoretically appeal to kids better. Aside from creatinga lot of fan animosity towards the character and being perceived a poor (and much looser than usual) adaptation of the original story, it led to a ratings slump the series never completely recovered from. It also led to Kunihiko Ikuhara's departure due to frustration over the lack of creative control (which also led to his formation of Be-Papas and Revolutionary Girl Utena)
Fan Nickname: The terms "Inner Senshi", "Outer Senshi," and "Asteroid Senshi." None of them appear in canon, though some are derived from terms that do appear. The Inners are given the title "The Four Soldiers of the Guardian Gods" (四守護神の戦士, Yon Shūgoshin no Senshi), although this is very rarely used. The Outers are given the title "Outer Solar System Warriors" (外部太陽系戦士, Gaibu Taiyōkei Senshi), and use this name to refer to themselves in the anime as well. The Musicals use Naibu Taiyōkei yon Senshi ("Inner Solar System four Warriors") and Gaibu Taiyōkei yon Senshi ("outer solar system four warriors"), but these do not appear in any other media. The last group is simply known as the Sailor Quartet in canon. It should be noted that the term "Inner Senshi" is derived from the shortened form of the Second Group's name (Outer Senshi), not the musicals. Thanks to Jupiter's inclusion in the "Inner Senshi", many fans often think the producers "screwed up" by including an outer planet as an "Inner" Senshi.
Naru is the Official Energy Source of the Negaverse.
Naruru is "Sailor Guccicci" and Ruruna is "Sailor Channel".
Keep Circulating the Tapes: At one point, almost the entire series was available in the States: ADV released the first two seasons uncut and in Japanese (the sets were only missing Episode 67), and Pioneer/Geneon released S and Super S in both dubbed and uncut forms; they also handled the release of the three films (also in dubbed and uncut forms). However, Toei eventually revoked all international licenses for the show, and famously refused to license it to any one (until 2010; see below). It should also be noted that, despite fan interest, the Sailor Stars season was never released in the States.
Marth Debuted in Smash Bros.: In the United States the three movies were released in between Sailor Moon R and Sailor Moon S. Thus Neptune and Uranus made their debut in the Hearts in Ice movie for English dub watchers. Their silhouetted cameo appearance in the final episode of R not withstanding.
Missing Episode: Quite a few in international dubs. The English Dub, for example, skipped all these episodes: 2, 5, 6, 20, 42, 67, and the entirety of the fifth and final season Sailor Stars episodes 167-200. Also, episodes 45 and 46, the two parts of the first season finale, were combined into a single episode.
No Export for You: Sailor Stars (the final season of Sailor Moon). While other countries managed to receive that series (which edits to the Sailor Star scouts to cover up the fact that they're men who transform into women), it was never licensed in North America supposedly due to Toei treating it as a separate title (and the series creator realizing that most countries wouldn't tolerate the Sailor Star scouts who transform from men to women), nor had it ever aired in France, Hungary (since it is based on the French version), Sweden and Holland (both of the latter that ended at the R season).
Jetix UK's inability to air the third and fourth season of Sailor Moon should have probably have been a warning sign in regards to what it would do to Naruto.
The anime got a top-shelf remastered DVD release that has yet to leave Japan. All R1 DVDs of the show remain out of print and while the show is slowly, but, surely, airing in other countries again, Toei is only licensing the rights to air the old 90s dubs, with no plans to create new dubs that wouldn't be as embarrassingly campy as the 1990s dubs were. The anime still hasn't appeared on television in the United States since its days on Cartoon Network, with complexities over the rights providing a massive hurdle. FUNimation has mentioned on several occasions that they have tried to get the show, but have yet to succeed despite a strong working relationship with Toei.
Great news. Viz Media licensed the entire anime—INCLUDING Stars—and are giving it a full-on re-dub that's much more faithful to the original.
The Other Darrin: Almost the entire main cast was replaced in the English dub, mostly due to the show repeatedly stopping production for years at a time. For the main cast alone: Tracey Moore originated the role of Serena/Sailor Moon for the first 11 episodes before Terri Hawkes took over. Tracey Moore would only return sporadically voicing her in episode 15 and 21 before Terri Hawkes completely took over the role for the remainder of the first season, all of season 2, and the three movies. Then when it came time to dub season 3 and 4, Terri was on maternity leave and Linda Ballatyne took over for the remainder. Then for Darien, the role started off with Rino Romano, who was then replaced by Toby Procter starting in episode 11. Vince Corazza (who had previously voiced Allen) took over for the final 17 episodes of Sailor Moon R onward due to Toby's pay dispute with Optimum. Sailor Mercury was originally voiced by Karen Bernstein for the DiC episodes but replaced by Lisa Balkan for the third and fourth season. Likewise Stephanie Morgenstern voiced Sailor Venus for season 1 and 2, and was voiced by Emilie Claire Barlow for season 3 and 4. Barlow would also fill in for Katie Griffin, the main voice actress for Sailor Mars for the last 17 episodes of R as Katie was away filming a movie, though Griffin returned for the remainder of the dub. Lastly Tracey Hoyt was the original voice of Rini but was replaced by Stephanie Beard for season 3 and 4. Susan Roman who voiced Sailor Jupiter was the only one of the main cast to stay on for all 159 dub episodes and the movies.
On the Japanese side, Usagi was voiced by Kae Araki (who would later play Chibiusanote And is best known to video game fans as the voice of Felicia in most of her appearances) from #44-50, due to her regular VA, Kotono Mitsuishi, having to leave to get her appendix removed.
In Sweden the voice actor for Ali is changed for no appearent reason in the last episode he appears. What makes it weirder is that the original voice actor later appears in the series voicing Rubeus. Sailor Mars' voice changed about 58 episodes into the show.
In Portugal, Motoki's girlfriend Reika had a different voice actress every time she appeared (to add insult to injury, she also had a different name every time).
In Italy, Rei's first VA Alessandra Karpoff has also been the first VA for Michiru and the second VA for Makoto, replacing the original one in the SuperS and [SailorStars] dubs when she was unable to voice Makoto due to maternity leave, which led to her being replaced as Michiru's VA.
The European Spanish dub had a long gap between the dubbing of SuperS and Star, leading to a different company handling the Stars dub. This also led to most of the cast being replaced due to the original actors being hard to contact due to the length of time. Only Sailor Mars, played by Pepa Agudo, retained the same actress.
Short Run In Peru: The last 17 R episodes aired in Canada long before they aired in the USA (where they were advertised by the Cartoon Network as being the "lost" episodes.
Talking to Herself: Reika is played by Rika Fukami, who also plays Minako/Venus. This is actually avoided in the first season, but later played straight.
What Could Have Been: A number of the early character concepts for the franchise were extremely different by the time the first issue of the manga and first episode of the anime came together.
Originally, the five girls that form the original Sailor Team had unique◊ outfits.◊ And Sailor Moon's hair was pink. Other prototypes of Usagi had her with a cloak and a handgun.
Usagi's hair was originally going to change to silver when she transformed (as seen in later prototype designs), but Takeuchi was convinced to keep it blonde as it would stand out more. However, the silver hair was kept for her Princess Serenity form.
Takeuchi considered having the girls' eyes change color when they transformed, although this detail only made it into a special few colored illustrations. Ami's eyes were intended to change from dark to light blue, Rei's would change from purple to a fiery red, Makoto's would change from grayish-blue to green, and Minako's would change from blue to gold. In most final artwork, Makoto has green eyes in both forms and the other girls' Sailor forms keep their civilian eye colors.
Ami changed the most in development. At first, Sailor Mercury was going to be Minako's friend Hikaru Sorano, who already looked a great deal like Ami. Later, Takeuchi decided to make her a unique character...a cyborg girl with an accelerator who would eventually die from losing one of her body parts. Her editor objected, so Ami became a fully human character with an intellect on a level that made her seem less human (though Takeuchi did eventually revist elements of the cyborg idea with Hotaru).
Makoto was originally a delinquent gang leader named Mamoru Chino. This was toned down to people mistaking Makoto for a delinquent despite her not actually being aggressive.
Rei originally had the name Miyabi Yoruno, and the earliest proposal for a Sailor V spinoff (which featured Hikaru and Mamoru as part of the team) didn't have any Usagi present.
Haruka and Michiru's original concept was a pair of performers in the real-world all-female Takarazuka Revue, of which Takeuchi was a big fan. This is also why they were portrayed as lovers. While their hobbies changed, their status as lovers stayed consistent.
Takeuchi wanted to dramatically kill off all the girls in the battle with the Dark Kingdom in the manga, but her editor rejected the idea. She would later state she was baffled when the anime was able to get away with killing them off (even if they were resurrected by the Reset Button at the end).
The infamous Toonmakers produced live-action/American animated pilot that Toei passed on in favor of the English dub by DiC Entertainment.
Hotaru was originally going to have what was referred to as "a druid's staff", a small brooch Saturn on her bow, and her fuku color was going to be yellow-ochre.
According to this promotional video, these were the tentative dub names. An early English Kodansha website for Sailor Moon had an alternative set of localized names that were used at some other points in development of the DiC dub. Usagi was called "Celeste", Makoto was to be "Maggie", Minako would be "Monica", and Mamoru would have the name "Mark". Only "Amy" and "Rae" (later spelled as "Raye") were retained from the second listing of names. Naru and Motoki were also named "Nadine" and "Michael".
Diana was supposed to be a fairy that was found by the Senshi on the Moon, who would accompany Usagi and Luna and not get along with Luna at all. Though the fairy character was dropped, her name and certain character traits were kept and used for Luna and Artemis' daughter from the future.
Word of Dante: It's generally accepted by the fandom that the R in Sailor Moon R stands for Return and/or Romance. This has never once been confirmed. In fact while the eyecatch for Sailor Moon S states its full name (Sailor Moon Super) the eyecatch for Sailor Moon R simply calls itself Sailor Moon R. Suggesting that the R in Sailor Moon R stands for...R.
Word of God: Only women can be Sailor Senshi. There cannot be a Sailor Earth because Tuxedo Mask has Earth's Sailor Crystal. Because of this, Naoko Takeuchi was not pleased that the anime changed the Sailor Starlights from crossdressers to Gender Benders...though as the anime also clearly depicts their true forms as female and their male forms as fake, it doesn't actually contradict this.
She also never explains why only Tuxedo Kamen has a Sailor Crystal.
Sailor Moon is currently one of the most requested shows for Toonami on [adult swim], after the 1992 anime was a network darling during the block's early years, though it hasn't been specified whether it's the 1992 anime or 2014's Sailor Moon Crystal.
