Sailor Pluto always had this veil of mystery around her. She was introduced in Sailor Moon R, WAY before any of the other Outer Senshi were. As the guardian of time, she seems to be the second most powerful of the senshi, only loosing out to Sailor Saturn. I don’t know much about Setsuna, but she just always seemed to know more than she let on, and always seemed like a classy and graceful lady. The green hair, red eyes, tan skin, and height also made her stand out much more than any of the other girls in the series. Also, she has that nifty Garnet rod, which could probably put Sora’s keyblade to shame any day of the week.
