Saturn Starseed
Japanese: Episode 197
NA: N/A
This starseed represents Saturn. It is inside of Hotaru's body most of the time, but it is taken by Sailor Uranus while she was proving herself to Sailor Galaxia. Interestingly enough, this was also matured early when Sailor Saturn awakened to fight Queen Nehelenia... which was all part of Sailor Galaxia's plan to get a mature starseed.

(Saturn does not transform on camera (T_T)
