Next final fantasy optional boss in KH should be Shuyin in my opinion.

 

Shuyin? I don't think he had enough... presence? He was only there for X-2 and even then how many people know who he even is? It should be Gilgamesh! Think about it: Legendary weapons collector + Keyblade...

I think it should be Gilgamesh or Rubicante.

Is that Sora? He has the same shoes and everything. lol joking.

never heard oh him im not that much of a ff fan

that guy really does share some apperiance of sora.

I'll share in your despair

 

 

But I'm not sure if any other FF characters matter other than Squall/Cloud/Tifa/Sephiroth/Areith. I mean, if he's there- he'll get mostly unimportant lines while everyone just staaaares are wonders who he is.

I doubt Shuyin would be a boss, rather a party member or summon. And there are many Final Fantasy characters that they can't put in this game becasue they would probably confuse the young. I sound like Disney now but I'm really with Square-Enix.
