He is the Servant of one of the series' main heroines, Rin Toosaka. Due to an incomplete summon, he apparently has no memory of his previous life or identity. Archer is sarcastic and cynical—but under his hardened exterior lies a complex and dark personality that unfolds throughout the story. Though skilled with ranged weapons, he can hold his own in melee combat. Archer considers Shirou Emiya's idealism to be weak and delusional, recognizing Shirou's mentality of "wanting to save everyone" as naive and impossible.
