A character named Cid features in every single one of the main (numbered) Final Fantasy games. The character was first introduced in Final Fantasy II (1988) (although when Final Fantasy (1987) was ported to the PlayStation, he was retro-ed into the game). However, Cid is never the same character from game to game, although he is often the owner of the airship.
