Usagi is are star of the show! Quite possibly also the most, laziest, whiniest, alround lump of all the Senshi and there allies. Yet, she just wouldn't be Usagi otherwise!

Usagi first finds out she is Sailor Moon thanks to Luna, a black, talking cat she finds on the way to school one day. She is forced to fight against the Negaverse by Luna, and if not for Tuxedo Kamen(mask) she would have been toasted many times in the early get go. Yet she stuck with it, and eventually she got some friends to help her fight

Usagi is known, as I stated earlier for her lazy actions, and her well known crying, or complaining if something isn't exactly going her way. She though, eventually becomes a true leader to the other Senshi and becomes a force to be reckoned with as she becomes even more power in further seasons(eventually becoming, Super Sailor Moon in S, and Eternal Sailor Moon in Stars, the final Season).

Her real love interest is Mamoru Chiba, or Tuxedo Kamen. They have been destined to become a couple for a 1000 years, and eventuall in the future, they do become married and have a child named Usagi too or Chiba-usa(Reeny in the U.S.) who actually comes from the future in Sailor Moon Romance.

All in all, Terri Hawkes does a good job as Usagi, but if you really want to see Usagi in all her laziness, I recommand the Fansubs to hear her in all her glory :).
