The King of Dragons, Bahamut
This respect thread on Final Fantasy's flare-spitting dragon isn't just for one specific game.
This respect thread covers all of the games (Advent Children included) and the awesomeness that is Bahamut.
I always liked the three Bahamuts in No.7: Normal, Neo and ZERO. The Bahamuts in No.8 and No.10 were awesome too.
Even if you dislike RPG's you have to give Bahamut the respect he deserves.
