Name etymology

Usagi's name is a pun on the phrase "the rabbit of the moon".
This derives from a Japanese children's story about the rabbit that is said to be
visible in the Moon's face, much like the Western Man in the Moon.

(The manga translation, which otherwise uses the standard American names
for the five Inner Senshi, gives her the nickname Bunny to partially preserve the pun;
many other localizations, such as the German and Polish, give her name as
"Bunny" in both the anime and manga.)

Similarly, "Serena" is probably at least in part a play on the word
Selene, a moon goddess in Greek mythology who fell in love with a shepherd named
Endymion. It also derives from the name of the moon princess, which is alternately either
"Selenity" (from Selene) or "Serenity" (from the Sea of Serenity on the moon).

(In an early DiC promotional tape that advertised Sailor Moon to television stations,
Usagi was called Victoria. Another preliminary name, that appeared on Kodansha's
English website in an advertisement for the series, was said to be Celeste.)

Transformations

Most of Usagi's anime transformations involve the use of shiny red or pink
ribbons that form the
leotard, boots, and gloves. These ribbons come
out of her brooch. When her detransformation is shown (which is rare),
these ribbons unravel from around her body and go back into the brooch,
leaving her in the clothes she was wearing before she transformed.
The one exception is her transformation to Eternal Sailor Moon,
in which feathers are substituted for the ribbons.
