|“||Stay back. This is a fight for me and me alone.||„|
|~ Cecil, confronting his dark side.|
In the English version of the 3D remake originally released for Nintendo DS, as well as in Dissidia Final Fantasy, Cecil is pronounced /ˈsɛsɪ̈l/ (seh-sil), as opposed to /ˈsiːsɪ̈l/ (see-sil), the pronunciation more commonly found in North American English. The Japanese form (Seshiru) seems to back this up. However, the bonus disc included with Final Fantasy XII's collector's edition pronounces it the other way.
Cecil wears dark armor that covers his body and face while he is a Dark Knight (the 3D render shows his eyes). When he becomes a Paladin, Cecil wears a blue and white armor that reveals his appearance: shoulder-length white hair, blue eyes, pale skin, and a tinge of purple on his lips. Even though Fusoya claims Cecil resembles his father, Kluya, in his youth, it is stated Cecil greatly resembles his mother, Cecilia, even being named after her. In Final Fantasy IV: The After Years, Cecil wears a suit of white armor, but with dark spikes on the knees and pauldrons, and a brown cloak with blue stripes around the neck.
Cecil is a strong and gifted knight, gaining the respect and admiration of his men during his captaincy of the Red Wings. Although being raised by the King of Baron, Cecil is modest, shy, and insecure. He struggles with showing his emotions, his meekness catches others off guard, ill-fitting his initial role as a Dark Knight. Cecil struggles with his sense of identity and morality; he comes to hate himself for blindly following his King's orders to the detriment of others, and promptly loses his sense of self as a result. By becoming a Paladin and bonding with others, he gains a semblance of who he is, a recurring theme in the game that he shares with many characters.
