Before explaining my choices, please be aware that I've tried to be as objective as possible and have tried to create a list representing all incarnations of Sailor Moon, not just the anime. This list is not a list of my Top 10 Favourites (if that were the case, more than half of these villains wouldn't be on it) but a list of who I feel were the greatest villains to face Sailor Moon and her Senshi. So, now that that's over with. Let's get on with who they are and why I picked them! (Also, beware spoilers may be abound!)
#10. Professor Tomoe (Anime) - As truly the most comedic villain, Professor Tomoe appeared as the "mysterious" villain of the third series of the anime. With his big grin and screwball behaviour, Tomoe proves that sometimes humour is the best policy.
#09. Sailor Chi and Sailor Phi (Manga) - In a story arc which featured way too Sailor Senshi (probably the leading cause of Otaku Senshi), Sailor Chi and Sailor Phi appeared and single-handedly ripped their way through Sailor Moon's companions. They managed to bring down the Starlights and later Princess Kakyuu in one of the most gruesome deaths in the manga.
#08. Wiseman (Manga) - As one of the most manipulative villains around, Wiseman poisoned the minds of the people of the Black Moon clan and even managed to turn sweet little Chibiusa into a lean, mean Sailor Moon-hating machine. So why does manga Wiseman get chosen over anime Wiseman? 'Cause manga Wiseman is a motherf*cking planet!!!!
#07. Fish-Eye (Anime) - There were a lot of sympathetic villains throughout the series from the conflicted Nephrite to the love-sick Esmeraude, but no one quite topped Fish-Eye. Crushed by Mamoru's rejections, Fish-Eye discovered Sailor Moon's identity and the holder of Pegasus all in one night but instead of truly giving them up, Fish-Eye in the end ended up a hero. Also, there's a major plus for him being a great comedic villain and transvestite.
#06. Eudial (Anime) - In the anime landscape of Sailor Moon, it's hard to find a competent villain who doesn't spend 20 episodes looking like a fool. However, Eudial proved to Moonies that there is such a thing as a competent villain. She was a smart cookie whose inventions could have easily torched the Senshi for good were it not for various plot devices. She was also the only character to actually figure out the true owners of the Talismans AND she nearly got away with them too! Too bad Bimbette -- I mean Mimette - killed her off.
#05. Zoisite (Anime) - If any guy deserves to be called a bitch in a non-derogatory way, it's Zoisite. Manipulative, cunning, feisty and deliciously devious, Zoisite made for one of the most interesting villains around. He plotted Nephrite's death, nearly skewered Tuxedo Mask and went toe-to-toe with Makoto and lived to tell the tale. On top of that, Zoisite ended up being one half of one of the sweetest couples in the series.
#04. Prince Demando (Musicals) - Fan-favourite Prince Demando is one of the creepiest villains around (seriously, preying on a 14-year-old girl? Yuck!) and yet has a surprising amount of fangirls. So why is he on this list? He's on this list because he was played by a she once. In the Black Lady musicals, Prince Demando (as played by Hikari Ono) dazzled audiences with "his" amazing dance skills and belted out one of the greatest villain songs in the history of the musicals. Freed from the creepy chains of his other counterparts, Demando ended up a conflicted young "man" who proved to be yet another heroic villain.
#03. Black Lady (Manga) - Perhaps one of the most popular villains, Black Lady turned evil because she thought she had a crappy birthday party in the anime (yeah, what a good origin story *rolls eyes*) but in the manga it ran deeper than that. Manipulated by Wiseman, Chibiusa turned evil and became one of the most menacing villains Sailor Moon would face. Only after the death of her best friend (Sailor Pluto), did she turn back in one of the most gut-wrenching scenes of Sailor Moon.
#02. Sailor Galaxia (Musicals) - Another insanely popular villain (particularly the anime version), Galaxia was a powerhouse who ended up being given the "I'm really a good guy inside" backstory for the millionth time in the anime. While this was still partly present in the musicals, Galaxia's role as a galactic dictator was emphasized and she belted out the most sizzling villain song from the musicals ("Galaxia Gorgeous"). She killed off all of Usagi's friends, took her lover and showed audiences she was one bitch you don't want to mess with. Okay, so she does that in the anime too, but what's the difference? Sailor Moon gets mad and fights back. Oh, and Galaxia comes back to settle the score with hordes of new villains.
#01. Queen Beryl (Manga/Musicals) - As the villain who has been adapted into the most versions of Sailor Moon, there's no doubt Queen Beryl is the greatest Sailor Moon villain. She's the first, the sexiest and one of the most dangerous. What makes her manga/musicals adaptation stand out more than her fiercely furious anime version and her voluptuously villainous live-action version (remember her telling Sailor Moon that SHE was the true villain? Hoo hoo!) is the emphasis put on her backstory. As the byproduct of unrequited love and messing with magic, Queen Beryl became the vessel for Queen Metallia to bring down the Moon Kingdom. While she's more menacing in the manga, I've tied the musical version here because of the heart-wrenching duet she has with Sailor Pluto.
