C - Sailor Moon. The language that everything ultimately revolves around and whenever caught in a pinch, reveals plot defying secret moves that solves everything, yet sets the stage for an even more powerful enemy later. Other Sailors have complex feelings towards her, because she is childish and whimsical, and is more caught up in romance than her royal responsibilities, and she is a bit of a crybaby.
Javascript - Sailor Chibi-moon. She is Sailor Moon's daughter from a thousand years in the future. She powers up her mother, but her power is quite limited on her own. Whenever she's in a bad situation, she cries, and a huge amount of destructive energy that can be seen from miles away, and is hard to calm down. She has more pantyshots than all of the other characters combined, but this is mostly used for comedic effect. She can also travel through time, has a crush on her father, and is sorely lacking in erodoujin.
LISP - Sailor Mercury. The intellectual of the group. She is smart and shy, and though everyone who knows her loves her, she has trouble making new friends. She can perform math that completely bypasses logic and can throw out a line of completely unintelligible nonsense to prove that she is right. She didn't have any offensive attacks for a long time, so her popularity suffered as she was deemed useless. This soon changed and she was given powers on par with the rest of the sailors, but some people never forgave her.
Pascal - Sailor Venus. A nice girl who is obsessed with idols and loves to sing and dance. She is very pretty, and strong -- on the rare occasion that someone has given her a proper plan. She was fighting evil on her own before meeting up with Sailor Moon and can be (poorly) disguised as Sailor Moon. She rarely makes good grades and is prone to taking advice from a cat. She is willing to change herself endlessly to please others, but is nevertheless doomed to never be loved.
Ruby - Sailor Jupiter. A tall tomboy who a bit clumsy. She is actually quite girly, but is embarrassed to admit this to anyone. Her dreams include being a good wife one day, but she is socially awkward and has had her heart broken before, so she is hesitant about romance again.
C++ - Sailor Mars. At heart, she is a nice girl, but she is quite quick to anger towards Sailor Moon's failings and is sometimes overly blunt. She is quite intelligent on her own, and can be quite elegant. She tries very hard at everything she does, and will try even harder to disguise the work she has put into something, so as to make it seem that things come easy for her.
Perl - Sailor Saturn. She is a frail girl, the daughter of a mad scientist who sold his soul to the devil for a chance to have a loli of his own. Because she is inhabited by the devil, two lesbians want to kill her, but Sailor Moon saves her and tells them to fuck off. Her powers are limited to either being useless or destroying an entire planet, killing herself in the process. She is good friends with Chibiusa.
Java - Tuxedo Kamen. Sailor Moon's love interest and future father of Chibiusa. He is as intelligent as Sailor Mercury, but never seems to apply it. He rarely cares enough to actually confront villains, but will save Sailor Moon when she is in trouble, which is always. However, he is prone to being brainwashed to attack her, and dying and being resurrected by plothacks. He has probably committed statutory rape against Sailor Moon.
Symta - Queen Beryl. A hateful cunt who uses her homosexual minions to steal the energy out of people, so that she can awake a monster, destroy everything that is good in the world, and begin her rein of darkness. She is in love with Tuxedo Kamen, so decides that the best way to win his heart is to destroy everything that he has ever loved. She is also quite ugly.
BASIC - Sailor Pluto. Her powers are a bit unknown, because she spends most of her time guarding a door that only Chibiusa uses, and that other might use, but don't have to achieve the same effect. She sometimes leaves this door guarded by a small kitten, so her functions must not be very important. Her core personality changes quite often and it appears that she cannot recognize her allies on sight.
Assembly – Sailor Galactica. She is the most powerful Soldier in the universe. She defeated the Chaos, an evil so pure that it could only appear in a children's show, by locking it in her body, causing her to become twisted and evil in the process. She is defeated by Sailor Moon, who used The Power of Friendship to exorcise the evil during the battle that had so much nudity that it caused the entire fifth season to not be licensed in North America.
