Sailor Saturn is also a very mysterious scout. She used to be evil (she was possessed by Mistress 9) but somehow became good. She also has immense power, which in the beginning of Sailor Moon Sailor Stars Sailor Pluto senses will be useful. It is through a burst of energy on her part that Sailors Uranus, Neptune, and Pluto get a power upgrade and become Super Sailors. She starts out in Sailor Stars as a baby (having been transformed into one at the end of Sailor Moon S) then grows back to her original size and age at a startling rate.
As for henshin, here is a picture of hers, although the name of it is not available:
Like Sailors Uranus and Neptune, Sailor Saturn has two attacks. One is called Silence Glaive Surprise, which makes use of her hand glaive. (A glaive is a symbol of a senshi of ruin.)
The other is called Silence Wall. She also has the power to destroy whole planets, which is called "Death Reborn Revolution!", but it costs her her life.
As a civilian, she is Hotaru Tomoe, the shy-natured daughter of the evil Professor Soichi Tomoe. Her name means "Firefly sprouting from the earth". Her mother, Keiko, died in a fire. Hotaru is secretive, taciturn, and thoughtful. She and Rini, who are close in age, are very good friends. She also has a special phone number that goes right to her bedroom. Her blood type is AB. Her favorite color is purple. She likes nihon soba (Japanese noodles) but hates milk. She collects lamps as a hobby. She enjoys world history but doesn't do well in P.E. She excels in first aid and dreams of being a nurse.
