Cid

A character named Cid is found in most Final Fantasy games and somewhat of a game trademark. Characters such as Biggs and Wedge have similar reccuring rolls.

Cids are often very mechanically minded and are often portrayed as engineers. They are often the source of the airships that the player uses toward the end of the game.

Cids are often several decades older than the main cast, and is often portrayed as a fatherly figure. A common trait is for a Cid to either have a biological daughter (such as Cid Pollendina from Final Fantasy IV) or adopt one (such as Cid del Norte Marquez from Final Fantasy VI).

Final Fantasy IV
Cid Pollendina is a player character in this game, and he is Cecil Harvey's childhood friend. He designs airships for Baron's Red Wings, however, he does not like his inventions used for malevolent purposes.

Final Fantasy VI
Cid del Norte Marquez is a non-player character in this game. He does experiments for the Empire, and invented the Magitek process. He raised Celes Chere as if she were her own daughter.

Final Fantasy VII
In this version, Cid Highwind is a player character.

Final Fantasy XI
Cid appears in this incarnation as an NPC in the nation of Bastok. He is a Hume and the most prominent engineer and inventor on the world of Vana'diel. Player characters in the game who come from Bastok can expect to do a few quests to help Cid acquire items to make his fabulous inventions.

In addition, in the on-going storyline centering around Chains of Promathia, Cid takes a prominent roll in helping to invent airships, which gives him more of a link to previous Cids of other Final Fantasy worlds.
