Queen Beryl

"You haven't seen the last of me!"

- Queen Beryl (DiC dub) "You'll pay for this, Princess! I cannot and will not forgive you for once again trying to take Endymion away from ME!!!!!!"

- Queen Beryl (Viz dub)

Queen Beryl is the main antagonist of the first season of the anime Sailor Moon. She is the queen of the Dark Kingdom (also known as the Negaverse), and serves the evil spirit called Queen Metalia (also known as the Negaforce). She commanded the Dark Kingdom to crush the entire Moon Kingdom.

During the first half of Sailor Moon, Beryl was trying to gather energy for Queen Metallia. She sent Jedite (Jadeite) to steal energy from people, but Jadeite's plans kept getting foiled by the Sailor Scouts. In Episode 10, Jedite fought them himself but was defeated, and as punishment, Beryl condemned him to eternal sleep and sent Neflite (Nephrite) to gather energy. Neflite's plans were foiled every time, but starting from Episode 18, Beryl began looking for the Imperium Silver Crystal. After the death of Neflite, Zoycite (Zoisite) was given the task of finding the crystal.

Using Neflite's Black Crystal, Zoycite tracked down the seven people with the Rainbow Crystals inside them, though some were taken by Tuxedo Mask, and one by Sailor Moon. Beryl also wanted Tuxedo Mask, who was really Prince Darien/Endymion, on her side, but Zoycite tried to kill him in revenge for scratching his face, so Beryl killed Zoycite as punishment for disobeying her. Afterward, Beryl and the Negaforce turned Darien (Mamoru) evil. However, by this time the Rainbow Crystals had combined into the Silver Crystal, which Sailor Moon, who was really Princess Serena, possessed now.

From this point on, Beryl's fourth and strongest general Malachite (Kunzite) tried to find and kill Sailor Moon to take the crystal from her. He failed each time, and was eventually killed by Sailor Moon. In the final episode (which proceedes its sequel series, Sailor Moon R, though it is often treated as a second season instead of a different show), the 5 Sailor Scouts headed over to the Dark Kingdom to stop Beryl, but Sailor Jupiter, Sailor Mercury, Sailor Venus, and Sailor Mars were all defeated by the Doom and Gloom Girls, who are themselves killed by the Sailor Scouts in the process.

Beryl teleported Sailor Moon to the Dark Kingdom where she commanded Endymion to fight her, but she found a way of healing him and as Beryl threw a gigantic crystal shard at them, Darien threw his signature rose attack at her, seriously injuring her, but also fatally injures Darien. In the original uncut, Queen Beryl then berates Darien for protecting Sailor Moon and for not choosing her until her skin where the rose hit begins cracking like porcelain. She realized that the rose is his energy for the love of Sailor Moon. Queen Beryl then sinks to the floor, yelling "I refuse--I refuse to believe that!" The Negaforce gave Beryl a final chance and combined with her, transforming her into a giant form, but Sailor Moon transformed into the Moon Princess and used Cosmic Moon Power, creating a giant energy ball that destroyed Queen Beryl.

Trivia

 * In the Super Famicom/Nintendo video game "Sailor Moon: Another Story", it is revealed that she used to be a sage before she became a queen of the Dark Kingdom after joining forces with Queen Metallia.
 * While she was a villain in the manga, but an ultimately tragic figure who was manipulated by Metaria into her crimes in her past and current incarnations, and ultimately doomed not by her villainy, but her own belief that she was beyond redemption at this point. In the 1990s anime, she is a straight-up evil villain who willingly and loyally serves Metalia.
 * In the Sailor Moon videogames, Queen Beryl herself is the most recurring boss in a similar way as to Ganondorf from Legend of Zelda or Bowser from Super Mario Bros. Those games being Sailor Moon for Super Nintendo/Super Famicom, Sailor Moon: Another Story, Sailor Moon (Arcade Game), Sailor Moon (Gameboy) and Sailor Moon (Sega Megadrive).
