Worst (Tiers) Character in a Fighting Game?

This could be an interesting discussion. Every game has that ONE characters that is the pun of every joke regarding balance. SF2 Gief, VSav Anakaris, MvC2 Roll, and even now there are jokes aplenty at the expense of UMvC3 Hsien-Ko. My real question is: What is the worst, in regards to tiers, character in a game you know of? Name any fighter you want, be it big, obscure, new, or old.
