Cid Del Norte Marquez is a non-player character from Final Fantasy VI. He is the chief genetic engineer of the Gestahlian Empire who invented the Magitek process. Born in the fifth year of the nation of Vector, Cid is a member of the Marquez bloodline of patriotic scientists of the northern state of which became Vector in the war of fifty years before the game's beginning. His Japanese surname is alternately spelled as Del Norte Marguez or Marguz.
Aside from working in the Magitek Research Facility, Cid cultivated a veritable collection of exotic flowers in a greenhouse, his favorite being roses. As Celes Chere grew, she would help him in the greenhouse, where Cid named his favorite flower after her and eventually gave it to her to adorn her quarters.
Cid wears a yellow coat with red decorations, though his artwork shows that underneath it he wears a black and white outfit that appears medieval, with black shoes with red decorations on them. Cid has a red moustache (grey in the SNES sprite).
Though Cid is devoted to his research, he is not strongly loyal to the Empire. Cid has selfless motives, and though he is unwilling to fight, he attempts to solve problems through diplomacy, and believes that the espers should not be killed solely to further his research. Cid is also close to Celes, and acts as a father figure for her.
Cid invented the process of Magitek, which involves the extraction of magic from espers and the infusion of the power into humans. Magitek was used to create the army the Empire is known for. Cid's first guinea pig, Kefka Palazzo, underwent the process as a young man, and the rudimentary experiment twisted his mind, and Kefka became unpopular. Cid refined the process and used it on a two-year-old child named Celes. The experiment was a success, and Cid raised Celes like his own daughter. Cid had always been against the war and resented his discoveries and inventions being used in it. Unknown to Emperor Gestahl, Cid had delayed his findings by at least a decade.
Cid did not discover the true secret of extracting magic from espers was to reduce them to magicite, their remains after they die. It took Locke Cole and several of the Returners to show him this and as a result, Cid joins the Returners and petitions Gestahl to stop the war after helping Locke and his friends escape the Magitek Research Facility. He helps represent the Returners in a banquet with Gestahl and afterward, he follows Setzer Gabbiani to try to rebuild the Blackjack. His suggestion is to remove the Blackjack's casino so as to increase the speed, but Setzer does not want his help and so Cid leaves in a huff.
Gestahl only uses the peace offering as a set up for him to obtain more espers and he no longer needs Cid. Kefka uses the powers he has obtained to defeat Gestahl and destroy the world by shifting the face of the planet by moving the Warring Triad out of alignment. One year later in the World of Ruin, Cid lives on the Solitary Island with Celes. He spends the year taking care of her, but becomes ill. Celes feeds him and depending on the quality of the fish she catches Cid either lives or dies. If he dies, Celes attempts suicide by jumping off a cliff, but falls into the water and splashes on shore, still alive. When she comes across Locke's bandanna her hope for her old friends to have survived is renewed. She finds a note left by Cid showing her the location of a raft he made to use to go search for others. If he lives, Cid shows Celes the raft personally and stays behind on the Solitary Island while she departs.
Continuing with the Spanish references, 'Del Norte Marquez' may be a reference to "Del Norte Márquez", a composite Spanish surname.
Del Norte means "from the North".
"Márquez" means "Son of a Marquis", a noble Spanish last name. "Marquez" is also a French second-personal plural that refers to marking or writing something down, or to remember something by using a mark.
- When Cid nan Garlond is suffering from amnesia in Final Fantasy XIV, he goes by the name Marques, referencing Cid from Final Fantasy VI.
