Users: Usagi Tsukino/Sailor Moon/Princess Sailor Moon/Princess Serenity First appearance: Act 25 Last appearance: Final Act Status: Destroyed.
The “maboroshi” (幻) in the Japanese name is often translated as “illusionary” or “phantom.” Official English translations now use the word “legendary.”
The Silver Crystal resided within Usagi for most of the time during the series’ run, even before its official introduction in Act 25. It never attached to the Moonlight Stick like the jewel did with the Moon Stick in other adaptations. However, it did rest on top of the Princess Harp.
Unlike its manga and anime counterparts, this Silver Crystal was not passed down from Queen Serenity to Princess Serenity. It always belonged to the princess. Additionally, the Silver Crystal destroyed the Earth as well as the Moon in the past.
The Silver Crystal’s shape could be changed: it transformed into the blade of the Princess Sword.
Every time that Usagi used the Silver Crystal’s power, Queen Metalia became stronger.
