Sailor Moon (Usagi or Serena Tsukino) officially spelled Sailormoon] in Japan, is a fictional character in the Sailor Moon media franchise, appearing as the protagonist and titular character. Sailor Moon is formally named Neo-Queen Serenity in the 30th century, but in the 20th century her civilian name, Usagi Tsukino becomes Serena Tsukino in the English-language versions. A carefree schoolgirl, she can transform herself into the de facto leader of the series' primary heroines, the "Sailor Senshi". Due to the series' widespread popularity in many countries and to her distinctive and oft-copied odango hairstyle, she has become one of the most immediately recognizable and iconic anime characters worldwide. No other character appears in all 200 episodes of the anime, and Usagi is present in all 52 acts of the manga as well as all 51 acts of the live-action series. Serena, Usagi's given name in the English-language versions of the series, derives from her being the reincarnation of Princess Serenity which means moon, the name Usagi went by in her past life. In the English manga she is mostly called by the nickname Bunny, which is the literal meaning of usagi. Her boyfriend for most of the series, Mamoru Chiba, calls her by the affectionate nickname "Usako" (a diminutive, the suffix -ko meaning "child"). I always loved the fact that Serena (Usagi) was not the bravest, smartest, sensible, or dependable person. She could be a bit of cry baby and scaredy cat.

Queen Beryl is the commander of the Dark Kingdom. This is the first animated depiction of the original manga character.

Queen Beryl's goal is to find the Silver Crystal and take over the world. She had four generals to assist her and her cause; the Shitennou, Jadeite, Nephrite, Zoiste and Kunzite.

Initially, Beryl attempted to collect energy for Queen Metaria's revival. Jadeite made several efforts to steal energy from groups of people by forging items with dark energy, only to be thwarted repeatedly by Sailor Moon. Beryl issued Jadeite an ultimatum, that if he failed to destroy the Sailor Senshi, he would be condemned to Eternal Sleep, a horrible punishment involving the victim being permanently frozen in crystal and being flung into an inescapable realm of profound darkness. As Jadeite failed to successfully carry out his final duty, Queen Beryl cast this sentence him and put Nephrite in charge. Nephrite tried to gather energy from one person at a time, but was foiled by Sailor Moon each time and was threatened with the same fate as Jadeite.
After Nephrite betrayed the Dark Kingdom and was subsequently killed by Zoisite, Beryl managed to harness some energy for Queen Metaria, who proceeded to give her a new task; find the Seven Rainbow Crystals to reform the Silver Crystal. Beryl assigned Zoisite with this task, although Tuxedo Mask was able to steal some of the crystals, and Sailor Moon obtained one as well, but was forced to relinquish to Zoisite. After discovering that he is the reincarnated Prince Endymion, Beryl ordered the remaining Shitennou not to kill Tuxedo Mask. However, Zoisite disregarded this instruction and stabbed him with a shard of ice, an action that led to his subsequent death. After these events, Beryl was able to possess Mamoru Chiba with Queen Metaria's essence, effectively brainwashing him.

As Sailor Moon still possessed the newly reformed Silver Crystal, Queen Beryl assigned Kunzite and Mamoru to find her and get the crystal back from her, though they refused to work together. Soon Mamoru was healed by Sailor Moon but recaptured by Kunzite and brainwashed again by Beryl after the former's death. After the Sailor Senshi locate and head out to D-Point, Beryl sent the DD Girls to bewitch them with illusions and kill them. After the deaths of all of the Girls and Senshi (bar Sailor Moon), Beryl transported Sailor Moon to the Dark Kingdom and arranged a fight between her and Mamoru. Sailor Moon frees Mamoru from the Dark Kingdom's influence, and he in turn manages to wound Beryl severely.

While appealing Queen Metaria to help obtain success, Metaria gave Beryl one last chance, possessing her and transforming her into Super Beryl. She fought Sailor Moon, who transformed into Princess Serenity and destroys the two queens with assistance from the spirits of her deceased comrades.
