Jeanne D'Arc (Alter)

Also known as Jeanne Alter (ジャンヌ・オルタ, Jan'nu Oruta?), she represents the Alter counterpart of Jeanne d'Arc. However, being designated as an 'Alter' does not indicate a mere alternate aspect of Jeanne d'Arc. Instead, she represents the embodiment of vengeance attributed to Gilles de Rais, the French Army's marshal who grieved for Jeanne d'Arc's death, fabricated by means of the Holy Grail shortly after Jeanne's execution in 1431. As a Heroic Spirit and dark counterpart of the actual Jeanne, she was originally summoned by Gilles in the Ruler class, but can be later summoned by Chaldea in the Avenger class.

Jeanne Alter exhibits a striking resemblance to her original counterpart, albeit with distinctive features. These include a notably pale complexion, yellow eyes, short-cut white-blond hair with an ahoge, and a darker color palette for her armor, flag, and cape. From stage 3 and onward, Jeanne Alter's armor becomes more revealing, and her shoes become high heels. Notably, she gains long flowing hair that reaches her ankles.

Jeanne Alter is characterized by a ruthlessly cruel and stern disposition. While she may retain remnants of her saintly nature, she serves as an embodiment of retribution towards humanity. She perpetually harbors distrust toward her comrades and her environment, and maintains a belief in God that lacks genuine faith.[1] She takes pleasure in denying God's existence to believers, considering it a source of entertainment, and vehemently disapproves the concept of "having faith", viewing it as malevolent.[4] Her disposition leans towards waging war alongside her companions against God, deriving pleasure from the act of slaughter to further her "cause."[1] Her being exhibits a penchant for unfettered destruction, even extending to the annihilation of humanity, as her life's purpose revolves around relentless killing until her strength is depleted.[4]

Through various circumstances, Jeanne Alter, despite her fictional nature, has been enabled to respond to summonings as a dark holy woman.[2] The specific details of her summoning remain shrouded in ambiguity. She does not exhibit immediate rebellion upon being summoned; however, her trust in the summoner, especially if human, remains consistently marred by suspicion. Additionally, under conditions of heightened tension, she may manifest fanatical laughter.[1]

Jeanne Alter displays a fundamentally embittered attitude toward her Master. However, she has been shown to have a multi-faceted personality, likely attributable to her basis, the original Jeanne d'Arc. Despite her prevailing bitterness, elements of respect and affection for her Master appear to exist at her core. Jeanne Alter lacks interests typically associated with girls; however, she shows hints of maiden-like desires. A comment from a Servant within the Avenger Class offers insights into her psyche. This comment, "To think that, in the depths of her consciousness, she wants to perform a strained avenge business while being surrounded by handsome men of her own liking!",[2] sheds light on the complex nature of Jeanne Alter's character.
