In episode blah-blah-blah, Fish Eye enrolled in a ballet class where they were performing Giselle, and became the ballet coach's muse shortly before taking his dream-mirror. Now, I, being of ignorant mind, have never heard of Giselle. The only thing I know about Giselle is from that Sailor Moon episode! However, I know what Swan Lake, the famous ballet by Piotr Illyich Tchaikovsky is, and I'm sure most of you know of it also. I have some ideas about which Sailor Moon characters should play the ballet roles...
Odette-Most definitely, undeniably, Fish Eye! Odette was turned into a swan by a sorcerer, but by moonlight she could again become Odette, the human. In the same way, Fish Eye was once a fish, but now he's human. Odette fell in love, only to be manipulated and betrayed. Thank goodness Fish Eye doesn't have to go through some of this heartache. He does, however, fall in love with Mamoru, only to be denied Mamoru's love in return. Odette is a beautiful, but tragic character; I think we can say the same for Fish Eye.
Odette's gang of swans-The Amazoness Quartet. No real reason, other than I think they would look incredibly CUTE dancing in ballet tutus! Can't you just see them prancing all over the stage :)?
Prince Siegfried (?)-I *think* the guy who broke Odette's heart unwillingly is called Siegfried ^^;;. The obvious choice is Mamoru, but other than the fact that he broke Fish Eye's heart ::holds up a "BOO Mamoru!" sign::, I don't really see any resemblance. Siegfried actually loved Odette, and was manipulated. It's really too sad that no one really loved Fish Eye romantically ::sigh::. I can kinda see Fish Eye with Prince Diamond, but Fish'd better keep his hands off my Yaten ;)!
Baron Rothbart-The cold manipulator. A shoo-in for this position is Wise Man from the Black Moon arc. He's ruthless, and he manipulated the Black Moon Family for his own selfish purposes. Wise Man is also one of the most heartless villians in Sailor Moon.
Odile-Ah yes, Rothbart's daughter, and his tool. I can kinda see Zoisite in this part, since he duped Tuxedo Kamen (assuming that Tux is in the role of Siegfried) quite a few times, but Zoisite doesn't strike me as an Odile. My interpretation of Odile is different from most people's; I see her as another person manipulated by Rothbart, who had the chance to turn good, but could not, and whose striking beauty was sealed off to the world (hey, she DID pass for Odette). My choice is Queen Nehelenia. My take on Queen Nehelenia is that she was brainwashed by the being in the mirror. She's a misunderstood soul cut off from the world, and she certainly is incredibly beautiful.
