Alright

Kyros = 100%
Raje = 100%
Cragon = 100%
Exodus = 100% [Could not find sprite sheet and had to decompile. Who knows how many sprites are missing]
Jinz = 100%
Karen = 100%
Valder = 100% [Thanks to Oskar]
Blade = 75% [Found a few sprite sheets and not sure if there are more. Not sure if decompiling is needed]

Roy = 55% [Is probably missing a lot of sprites. I have a few sheets and there are still sprites missing. If I decompile them, I don't know if that will be them all]

Ryddo = 0% [No sheet but I haven't looked yet. I decompiled some but sheet will be better once I find it]
Relax = 0% [I have the whole sheet. I just need to convert them]

Lord Shado = 0% [Suffers from the same problem as Roy. The creator himself lost the sprites too and remade some, he plans to make more but I need some of the old sprites that have been potentially lost]

Target = 0% [Not tried]
Deluge = 0% [New character. It's fine]

SSW and SSW vs SCD could have similar problems but they are not as severe.

I'm tired while I'm writing this

I think I will finish Target, Deluge, Relax and hopefully Ryddo first. The rest of them will be a pain to do
