To be added
The Princesses weren’t shown in any episode of the first anime but in the end credits of Sailor Moon S, the Sailor Senshi (except Sailors Pluto and Saturn) are seen with Princess Serenity in what seems to be their Princess forms.
- As princesses of their own respective celestial bodies, they wore dresses of their theme color, and their hairstyles remained the same.
- Though in some artworks, some Princesses’ hair colors matched their theme color.
- While princesses in their own rights, the Castles that float above their planets are revealed to be gifts from Queen Serenity.
- Fans speculate that there might be a kingdom on the actual planet, as we see in Codename: Sailor V, these planets hosted humanoid life as Ace was a soldier of the planet Venus and even has the planet’s symbol on his forehead.
