The daughter of Neo-Queen Serenity and King Endymion (the future Sailormoon and Tuxedo Kamen), Chibi-usa becomes Sailorchibimoon upon Sailorpluto's death after the guardian of time uses her "Time Stop." In the Infinity arc, she can transform into SuperSailorchibimoon with the aid of the second Holy Grail. In the Dream Arc, Pegasus gives her the ability to become SuperSailorChibimoon without the Holy Grail; at the end of the Dream Arc, she becomes SailorStarChibimoon.
