Setsuna is the Guardian of Time, positioned to watch over the Gate of Time alone for eternity. She has to watch over the flow of time and prevent disturbances, and cannot interfere in events that must happen. She has several "taboos" that she cannot break, one of them being that she can never stop time, but she breaks this taboo to save Uranus and Neptune in the anime, and she broke it in the SMR manga and was killed, but was reborn later. In the anime, she appears twice in SMR, once as a projection from Luna-P, the other when the Inner Senshi come to the Time Gate to go to the future, Neo-Tokyo. She reappears in SMS, when Neptune and Uranus's Talismans appear, and stays around until she breaks the taboo mentioned above. She then reappears for Stars, when Neherenia is trying to takeover the world and kill Usagi and anyone associated with her. It's been quoted that "when Pluto appears, you know all hell is going to break loose." She only returns to Earth for pivotal events. After meeting Hotaru, Haruka, and Michiru, she became close friends with them.
In both the anime and the manga, Setsuna is usually cold and frequently remains aloof from others, particularly the Inner Senshi. She is intelligent, very mature, and rarely shows any emotion. She is dedicated to her duties as the Guardian of Time, and as a Senshi. I'm not sure if this is in both the anime and the manga, but Setsuna is said to be interested in fashion and designing. Most of her past is unknown, and very little is known about her. She took Hotaru from her father in the anime during Stars. I don't know if there are any real differences in her personality between the manga and the anime.
Setsuna has very long, dark green hair, and it's difficult to judge just how long it is. In the anime, she always wears it in a bun with the rest of her hair hanging out, and in the manga she occasionally wears it down. Her eyes are maroon, and she has darker skin that the other Senshi. Both of her ears are pierced, and she wears dangling earrings. She is seen in formal clothing in the anime, and in the manga she usually wears that, but sometimes wears fashionable, casual outfits.
As Pluto, she has power over time, but her attacks don't seem to have any specific origin, they just do a LOT of damage. Her fuku in the anime looks to be a dark grayish-blue with dark maroon bows, but in the anime it's black with brownish-crimson bows. She has knee-length, highheeled boots. She has no sleeves, a gem hanging from her choker, and no stripes on her collar, but these change when she receives her Super form.
I think Setsuna is just soooo cool! Hey, gotta like someone with dark green hair, right? ^_- And her birthday's the day after mine o.O Anyways, I think she has the best attack (Dead Scream) and her henshin is awesome, and I don't know why, but I really like her fuku. Go figure. I like how she's so mysterious and cryptic. She seems a bit more... perky? in the manga... I mean, she grins really wide and stuff... and her death in SMR was so sad! ;_; *ahem* Well, anyways, I just think she's verrrrry spiffy and wish she'd appeared more... and what's with not including Cronus Typhoon in the anime? They gypped her! Poor Setsuna-san! ... Ok, I'll shut up about her now...
