As a noob, I haven't had the greatest experience against FG's, but I have had my bright moments and EMs (thank you Wings+Serket.) But, like the topic asks, the FG I absolutely hate the most is, drumroll please, JEZEBEL! I hate her! She has completely owned any attempt to defeat her, by me. At this point, if I know I am getting her next, I don't even bother.
