Cid is a loud and proud old man, boastful of his prowess with machines and of having the skill to back it up. Cid often doesn't make a strong first impression, reacting with offense when Tellah, Edge and Fusoya give him orders or question his technical skills. However, Cid is a good man with a firm belief of right and wrong, and cares for Cecil and Rosa. He has a fatherly streak with Cecil, whom he views almost like a son. He works hard to the point of collapsing from exhaustion and is known to be late coming home from work. In Final Fantasy IV: The After Years his age has not stopped him from being an active engineer and pilot, taking an equally stubborn Luca under his wing.
