Originally called Archetype Saber, he is the version of Saber (fate) that was to be used in the original Fate/stay night novel that was penned and left uncompleted. He would later make an official debut in Fate/Prototype as a Saber from an entirely different time tree, complete with his own characterization and contextual differences compared to the Saber from Fate/stay night.
