They had a big bridge and everything too.one word,
Jesu cripso I hate how Nomura has essentially shafted final fantasy in this series for the sake of promoting his own OCS into the series. I've said it many times before, but they honestly should've used him in KH 3. You have a bridge in Kingdom of Corona, plenty of final fantasy heroes weapons that he can "use" (create knockoffs of and use in battle) and just provide a challenge that we clearly weren't getting with the base game. After all, the one "secret" boss in the main game is a cakewalk if you know what you're doing.
Maybe Gilgie will be in FF7R2.
