A different aspect of the King of Knights devoted to cruelty, greatly unlike the case of the normal Artoria. She is referred to as Saber Alter. A behavior without futility, a cold-hearted personality that makes Artoria seem like a different person. Artoria Alter's personality changes vastly from her normal self upon being corrupted by Angra Mainyu, but she cannot be called a villain. She is more of a dark hero who is still an idealist clinging to her own values even after being blackened.
