diff.text: '''Tomoe Hotaru Tomoe''' is a weak and extremely introverted young girl who becomes the powerful '''Sailor Saturn''', the Senshi of Ruin and Rebirth. In Japanese mythology, the firefly is a symbol of rebirth. When she was first introduced, she was possessed by [[Mistress 9]]. She is later adopted by [[Sailor Neptune]], [[Sailor Uranus]], and [[Sailor Pluto]]. Her best friend is [[Chibi-Usa]]. Hotaru is the only Sailor Soldier to not receive a name change in the English anime.
diff.text: In the manga, Hotaru's mother died in a laboratory fire. Hotaru was only a small child at the time, and was severely injured. Her scientist father integrated technology into her body, and made her into a cyborg. The machine additions to her arms and legs were clearly visible, so Hotaru made a necessary habit of wearing long sleeves and tights with every outfit. During her recreation as a cyborg, her half-schizomad father planted an alien egg into her that made her into Mistress 9's physical host.
