Japanese Name: Hotaru Tomoe ("Firefly Sprouting from the Earth")
Hotaru transforms into the Melachiolic Fighter, Sailor Saturn. Hotaru is an isolated, lonely girl who has no friends, and is enrolled at Mugen Gauken Acadamy in the sixth grade. She possesses the ability to create an enormous amount of energy that can blast anything in her path, but she does this subconsciously. Hotaru's mother died when she was young, and thus she lives in seclusion with her evil father, Professor Tomoe. At first her father had a good heart, but he sold his soul to an entity known as Mistress Nine after a lab explosion killed Hotaru. In return for his soul, the entity allowed Hotaru to live. Hotaru later becomes friends with Chibi-Usa and with the Sailor Senshi. Sailor Saturn is the leader of the Outer Senshi. She is arguably the most powerful of all the Sailor Senshi, but she is severely limited by her weak consitution. As Hotaru, she is a caring and gentle soul, but as Sailor Saturn she has the power to destroy entities, fortresses, and entire worlds.
