Saber

Artoria has the appearance of a young girl in her early-mid teens with a slender and petite physique, soft skin, and green eyes. She has "finely textured" blonde hair that seems "as if sprinkled with gold dust". Her face shows some signs of naivety and displays elegance. She is more muscular than someone like Rin, leading her to believe her body is unappealing, but Shirou believes her to be very feminine. She normally wears shining armor with an old styled dress, made from old-fashioned blue cloth, underneath. She is actually older than her appearance would show, as her body did not age from the moment she pulled Caliburn from the stone to the time of her death.

Artoria is a strong-willed young woman who usually speaks truthfully but will lie if necessary. She is courageous, determined, and set on winning the Holy Grail. She constantly insists that she is a knight and king above all, and that her gender is of little importance to her and her role. She is resolute in following her own morals, regardless of the more viable, yet underhand, tactics being available. Artoria prefers direct, fair confrontations based upon codes of chivalry. Not even her hunger for the Holy Grail can make her abandon her code of honor.

This leads to regular conflicts with Kiritsugu over strategy within the Fourth Holy Grail War. While obtaining the Grail is of the utmost importance, rejecting her chivalry is something she will never do, even if it should put her at a disadvantage. If such came to pass, she would require her Master to use a Command Spell as recompense for treading upon her heart. A Master tends to do well with Artoria when they respect her rules, such as Irisviel being closer to her than her true Master, Kiritsugu.

She believes loyalty and respect should be shared between Master and Servant. Thus when a Servant kills their Master, Artoria is enraged to the point she may kill as punishment. If a Servant dies protecting their Master, she protects their sacrifice from ridicule, believing they died honorably.
