| Princess Serenity |
Princess Serenity shares the same appearance with her reincarnation, Usagi Tsukino; she has blue eyes, long pale blonde hair styled in two buns with flowing pigtails, and a golden crescent moon on her forehead to mark her status as a member of the royal family of the Silver Millennium.
Serenity wore a white flowing gown with white shoulder pieces disconnected from her dress, an intricately decorated bodice with gold hoops, with the bust defined by a row of golden beads. Trailing at the back, was a white gauzy bow with long fluttery ribbons. She also wore golden spiral earrings and a golden beaded bracelet on her right wrist.
In the manga, Serenity was fascinated by the Earth. Even though she was given orders not to go to the planet, she secretly visited there and met Prince Endymion. The two then fell in love.
During the Dark Kingdom's attack which caused the Moon Kingdom's downfall, Prince Endymion died protecting Serenity. She fell into an extreme grief due to Endymion's death, and committed suicide. Serenity's mother, the Queen, sealed away the evil and the moon in order to save the rest of the solar system (as seen in Volume 3), though unfortunately everyone involved on the moon perished.
Before her own death, the Queen used the Silver Crystal to give her daughter and others another chance at life, hoping in particular that, this time, Serenity and Endymion could find happiness together.
Season One: Dark Kingdom
From the beginning 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 9 that Princess Serenity's present incarnation is Usagi Tsukino.
Serenity was fascinated by the Earth, and longed for its greenery and wind. Even though she was forbidden to go to the planet, she would go there in secret, eventually meeting Prince Endymion. The two then fell in love.
During the Dark Kingdom's attack, the catalyst of the Moon Kingdom's downfall, Prince Endymion died protecting Serenity, and out of sorrow, she committed suicide. Serenity's mother, the Moon Queen, sealed away the evil forces of the Dark Kingdom, but as a result, the Moon Kingdom turned into stone, and Earth's history had to be restarted. Before her own death, the Queen used the Silver Crystal to give her daughter and others a second chance of rebirth, hoping in particular that, this time, Serenity and Endymion could find happiness together. As a result, Serenity's spirit was reborn and reincarnated in 21st century Earth as Usagi Tsukino.
Season Three: Infinity
After Sailor Pluto destroyed Tellu, Sailor Moon transformed into Princess Serenity. The Outers formally introduced themselves, and asked them why the Inner and Outer Senshi could not work together. The Outers apologized to Serenity for failing in their mission in preventing the Death Busters from infiltrating the Solar System and attacking Earth. They told them that it is their problem, and the other Senshi and Serenity will get in the way and get hurt. They also told her their ultimate mission is to destroy the Deity of Destruction.
- Even though the Crystal is far much more like the manga, Princess Serenity has yellow-blonde hair; like her original anime counterpart. However, her hair is noticeably a paler yellow-blonde than Usagi's, as opposed to the original anime, where Serenity had the exact same yellowish-blonde hair as Usagi.
