Sulphur vs. Kuja
Sulphur vs. Sephiroth
Sulphur vs. Fou-Lu - Puts up a respectable showing, but Sulphur's a tad better, even though I scale him against a whole army of Phantoms.
Sulphur vs. Ghaleon - Ghaleon gets a turn, but it's not enough.
Sulphur vs. Orlandu
Sulphur vs. Ash Lambert - well, if Sulphur didn't OHKO, this might be a match, but.
Sulphur vs. Albedo
Sulphur vs. Melfice - Spoiled.
Sulphur vs. Myria - Similar, but faces a smaller army.
Sulphur vs. Ryu3
Sulphur vs. Ryu4
Sulphur vs. Yuna - Yuna gets a turn, it's a fight from there, but I'm leaning this way. Sulphur accuracy is good, but so is Yuna evade. Close-ish. Could go either way.
Sulphur vs. Piastol - Spoiled.
Sulphur vs. Kefka
Sulphur vs. Zophar - Kneejerk.
Sulphur vs. Luca Blight
Sulphur vs. Yuri Hyuga
Sulphur vs. Profound Darkness - Form chain buffering, I'm thinking.
Sulphur vs. Jade - I tend to see Sulphur as about the same level as BoF/Lunar bosses.
Sulphur vs. Emelious - Evasive enough and not OHKO'd.
Sulphur vs. Jenna Angel - Form chain buffering.
Sulphur vs. Lady - Not sure.
Sulphur vs. Empyrea
Sulphur vs. Cloud of Darkness - Not sure.
Sulphur vs. Heat
Sulphur vs. False Althena
Sulphur vs. Isolde - Not sure.
My durability respect for Lady, CoD, and Isolde is kinda up in the air at the moment. Will vote when I feel like doing math.
