Character Design: I've always liked hippies. They have their heart in the right place far more than anyone on the opposing extreme, even if they're also blindingly wrong about a lot of things, so the character design of NeoFio speaks to me just a wee bit.
But only just. Very well done though, the flower child look.
Combat Usefulness: I don't recall ever using her.
Tilt: You know, one plant character was fine, especially when Turnip had a much more interesting story. The second plant character is completely unnecessary, even as an NPC, let alone a PC. Cross's "Let's abandon all attempts at making a sensible party!" syndrome strikes again!
Final Grade: D.
