Cid is a physical fighter, and equips bow and arrows, hammers, axes, shields, helmets, armor, gloves, and tunics. With the exception of the 3D release, Cid's hammers are two-handed weapons and thus he cannot equip shields while wielding one.
Cid's magic stats are the worst in the game, gaining no MP in any version.
Cid's ability is Analyze, also known as Peep and Scan, which functions identically to the White Magic spell Libra, displaying an enemy's HP, MP, level, and weaknesses. In the 3D release, Analyze scans all enemies when used. Cid has an additional ability in the 3D release called Upgrade, which allows him to use an attack item to add its elemental property to his normal attacks; for example, using a Bomb Fragment will make Cid's attack Fire-elemental.
There is an unused command found within the game's data, but it's only named in the original Japanese version, Airship (ひくうてい, Hikūtei?). The command is configured to target all enemies, but the command crashes the game when used. Given the name and positioning in the command list, it was intended for Cid.
