Super Sailor Chibi Moon
As she grows stronger, Sailor Chibi Moon gains additional power, and at key points her uniform changes to reflect this. The first change is first seen in act 33 of the manga, when the Holy Chalice of the future allows her to turn into Super Sailor Chibi Moon (or Super Sailor Mini Moon in the English anime). Later, Pegasus gives her a compact which lets her transform without the Grail. In episode 128 of the anime, this gift is what causes her to become Super Sailor Chibi Moon for the first time.
