Saber's True Name is Artoria Pendragon, better known as Arthur Pendragon and King Arthur, who is regarded as a male in history. She is the "Once and Future King" and a legendary hero of Britain known as the King of Knights. She wielded the sword from the stone, Caliburn, but it was eventually destroyed.
She later obtained Excalibur and Avalon from the Lady of the Lake.
Saber has the appearance of a young woman in her late teens with a slender 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. She normally wears shining armor with an old styled dress, made from old-fashioned blue cloth, underneath.
