Cid wears a navy blue jacket over a dark shirt with dark green cargo pants. He wears a white pilot's scarf that covers most of his shirt. Cid has blond hair and blue eyes and facial stubble. He wears a pair of goggles with a packet of cigarettes strapped underneath the band. Cid is a chain-smoker, and ends each battle by lighting a new cigarette. He wears leather gloves and boots, and his weapon of choice is a spear, although he also has an affinity for firearms as noted by an AK-47 and two M-14s in his "engineering room".
Cid is known for his foul mouth, as he curses a blue streak at several points in Final Fantasy VII. Several of his lines are "bleeped", appearing as a jumble of symbols. He does not bother about trivialities, and prefers going to the source of the problem, though sometimes seems wholly uncaring, such as during the party's visit to Gold Saucer to acquire the Keystone, where Cid sleeps while Cloud explains the mission to the Temple of the Ancients. He also sleeps on the Highwind during Cloud's breakdown, when Barret and the others discuss who should lead the group during Cloud and Tifa's absence.
