Template:InfoboxCharacter Princess Serenity was the princess of the Moon Kingdom during the Silver Millennium. Eventually, after the unfortunate and sudden destruction of the Moon, she was sent to the future Earth and was reborn and reincarnated as a fourteen-year-old girl named Usagi Tsukino. This is the first animated depiction of the original manga character.
Like several other manga-imported anime characters, Princess Serenity retains the same appearance as she does in her original incarnation. However, her hair is blonde as opposed to silver.
At climatic moments in the series, Usagi as Serenity sometimes gains a pair of functioning angelic wings. She does this during the final battle of Sailor Moon SuperS, to save Chibiusa when the two of them encounter Pegasus and also in the fifth and last season, during the fight with the fully-possessed Galaxia when she grabs the Sword of Sealing. It is unclear if this ability came from her past life, is Usagi's own power, or came from Eternal Sailor Chibi Chibi or Sailor Cosmos herself and the Sword of Sealing.
From the beginning to the middle of the series, Luna's task, along with awakening the Guardian Senshi, is searching for the Moon Princess. Mamoru also has constant dreams about a girl asking him to find the Silver Crystal. It is revealed in episode 34 that Princess Serenity's present incarnation is Usagi Tsukino.
Flashbacks in episode 35 and 44 show that Serenity fell in love with Endymion, the Prince of Earth. But Queen Metalia kills both Serenity and Endymion during the invasion of the Moon Kingdom. Serenity's mother, the Queen, was able to seal away the evil which had inspired the attack, but everyone involved was killed. The Queen then used the Silver Crystal to give her daughter, her love, and the Sailor Senshi another life, hoping in particular that, this time, her daughter and the prince would finally find happiness.
In the final battle against the Dark Kingdom, Usagi becomes Princess Serenity, and using the Silver Crystal and the combined powers of her friends, she is able to defeat Super Beryl. But as a consquence of using the crystal, she dies, but is eventually reincarnated back into Usagi with none of her memories intact.
Sailor Moon R
While Princess Serenity does not make any direct appearances, Mamoru constantly has visions and nightmares about Usagi/Serenity dying, although these turn out to be false and they were only sent by King Endymion from the future.
The second season also reveals that Serenity/Sailor Moon will ascend to the throne as Queen of Crystal Tokyo and the Earth under the name Neo-Queen Serenity.
Sailor Moon S
Sailor Moon SuperS
At the end of Sailor Moon SuperS, in episode 166, Sailor Moon transformed into Princess Serenity when she dove to save Sailor Chibi Moon. As they were falling, she was given powers from Pegasus, granting her functioning wings for her and Chibiusa.
Sailor Moon Sailor Stars
Princess Serenity makes her only and final appearance in the anime during episode 200 during her fight with Chaos Galaxia.
Sailor Moon R Movie
Princess Serenity makes an appearance during the climax of the Sailor Moon R movie, where Usagi transforms into Serenity to use the power of the Silver Crystal to stop the meteor from hitting the Earth.
Princess Serenity's name comes from "Selene", who in Greek mythology was the goddess of the moon who feel in love with a shepherd from Earth named Endymion. It could also come from Mare Serenitatis, or the Sea of Serenity, which is a lunar mare on the Moon.
- During some of the climatic battles of the original anime, Sailor Moon became Princess Serenity herself, implying she is at her strongest and most powerful while in that form, whereas in the manga, Sailor Moon defeats the main antagonists without becoming Princess Serenity.
