Fighter from FF1!!!

(SPOILER)FFIV: Rydia, Edge, Cesil, Kain and Rosa.
FFV: Gilgamesh and X-Death.
FFVI: Shadow, Interceptor, Kefka, Terra, Sabin, Edgar, Celes, Relm, Strago and Ultros.
FFVII: Tifa, Cloud, Vincent, RedXII, Barret, Cid, The Turks, Jenova, Rufus and Aeris.
FFVIII: Squall, Seifer, Zell, Rinoa, Quistis, Edea and Ultimecia.
FFIX: QUEEN BRAHNE!!!
FFX: Auron, Rikku, Tidus, Wakka, Lulu and Yuna.

However... I'm pretty sure there won't be any characters from FFIV-VI or FFIX.
