The chief engineer of Baron, is friend of Cecil, Kain, and Rosa. He lives in the town of Baron with his daughter, who often scolds him for his workaholic behavior. Since the loss of his wife, Cid has treated Cecil like his own son. Having discovered the ancient skill of levitation, Cid is credited with inventing the airship. After discovering that Cecil has been relieved of his position in Baron's fleet, Cid is locked away in the dungeon by Cagnazzo. After Cagnazzo is defeated, Cid escapes and gives Cecil access to his special airship, the "Enterprise". When the "Enterprise" crashes in the Underworld, Cid takes it back to the surface to outfit it with Mythril, which enables it to fly over magma. He rescues Cecil from the collapsing bridge to the Tower of Babel, and attempts to escape a pursuing Red Wings airship. He ultimately jumps off the ship and detonates explosives to seal the Underworld. He is thought to have been killed, but he returns to add Mythril and a drill to the newly acquired airship, the "Falcon", which he deploys against the Giant of Babel.
