*SPOILERS!*


Garland, Emperor Palamecia, Dark Cloud, Zeromus, Neo-Exdeath, Kefka, Sephiroth, Ultimecia, Necron, Yu Yevon and Shuyin all die or disintegrate or fade away in some way. Poor fellows.

Seriously though, here's some of the major death scenes I remember:

FFI - none
FFII - Scott, Josef, Minwu, Richard, Cid
FFIII - Desh (fake death), Elia, Dorga and Unne
FFIV - Too many fake deaths here, Tellah dies for good
FFV - King Tycoon, the four Warriors of Dawn (including Galuf), possibly Gilgamesh
FFVI - Cayanne's family, possibly Cid, possibly Shadow in the ending
FFVII - none... oh wait, Jessie, Biggs and Wedge. Plus one girl, but apparently you can dig her up in the Bone Village.
FFVIII - umm... Raine?
FFIX - Brahne, Garland and Kuja just after they stop being "bad guys"
FFX - Tidus, Auron, Jecht
FFX-2 - Tidus and Yuna get shot... oh wait, that was just a dream.
