Character Design: A green base colored cute little fairy that actually flies around! (unlike Guile who just hovers).
Combat Usefulness: Okay, let's see... Green innate with devastating magical abilities and Tech skills. She is only third I believe, in highest magical stat value out of all the characters. Her weapon type is rods, but she also happens to have a unique and special kind, which is also consistent with her whole design: The Flower Rod
She has a child-sized body due to the nature of her kind, which makes special type armors available to her giving her an incredible boost in her evasion value, if coupled with a pair of Winged Shoes (which also match with her character design!). Also, one of three characters that have the only Triple Tech in a Normal Game.
Tilt Factor: She gets quite a bit of character development during the whole Water Dragon Isle quest of the first part of the game. She also represents part of one of the themes which the game stands for: choices. That is, depending on what you do during the Hydra Marshes, and also during the time in which the dwarves assault her home; you get very different end results from them. This is why I believe she is key to a part of the plot in Chrono Cross, and why I'm more than fairly certain that her story path is actually the one true path that Serge would ultimately choose (it's not like he's a complete idiot, who would have no idea whatsoever as to what to do in an emergency situation, such as the one that was presented to him when Kid was poisoned).
Final Grade: A
