アーチャー

A mysterious warrior of unspecified origins and era who serves as the Servant to Toosaka Rin. Exuding a palpable aura of cynicism and sarcasm, Archer's worldview starkly contrasts with that of Shirou's, whose idealistic and naive aspiration to 'save everyone' he perceives as an unattainable folly.

Archer is Emiya Shirou from a possible future, a magus specializing in psychometry and object replication with a focus on swords. Though his replicas may be weaker, he can enhance them to surpass even the originals. In addition, true to his talent since his youth, his unparalleled marksmanship complements his magical prowess, making him a formidable and versatile combatant.

He also appears as an optional boss in Fate/Extra CCC. This is not to be confused with the playable Archer in that same game.
