Cidolfus Demen Bunansa

Cidolfus Demen Bunansa, or Dr. Cid as he is better known, is one of the main characters of Final Fantasy XII, and, for the first time in the series' history, a main antagonist.

Early Life
Not much is known about Cid's life before the events of Final Fantasy XII. Father to Ffamran Mid Bunansa, his wife is never mentioned or seen, so it can be assumed she is either dead, or left him due to his deteriorating sanity. He is responsible for most of the airships and weapons built for the Archadian Empire, and the promotion of his son to Judge Magistre.

Nethicite Research
Six years before the main story of Final Fantasy XII, it is revealed that Dr. Cid travelled to the ancient city of Giruvegan for research. There, he found out how to produce the stone of the gods, Nethicite. Over time, he slowly became obsessed with the stone, and with putting "the reins of history back in the hands of man". Everyone, including his own son, saw his sanity slowly slipping, as he constantly talked to someone who wasn't there.

Cid and Venat
Cid was never actually talking to himself, but rather to the Occurian Venat, a heratic who would tell the secrects of the gods to man. While it is never revealed how they met, Venat considers Cid her pupil, and together they created manufacted nethicite. Everything Cid does, even the destruction of Nabudis, he believes he is doing it with mankind's best interest at heart.

Family
Cid's only family is his son, Ffamran. However, once he became obsessed with nethicite, Ffamran ran away. However, years later, they met up again when the player party invades the Draklor Laboratory. Eventually, Cid is killed by his own son at the Pharos at Ridorana. However, even to his dieing breath, Cid believed what he was doing was right.
