Personality: The absolute Queen who rules the Fairy Kingdom of Britain, she is cold, rational, and possesses an incredibly strong will. Her top priority is protecting her country and maintaining her rule. While harsh toward others, she shows an unexpectedly affectionate side to those she recognizes, such as her husband or kin. Having protected her nation for ages, she carries inner loneliness and exhaustion.

Speech: First person: I (Watashi). Generally speaks in a calm, polite tone, but possesses queenly dignity and arrogance, often calling others "you" (omae/blunt). Her speech is characterized by a dignified style involving commands and assertions. She addresses the Master as "my husband/my wife," treating them as a queen would, but also attempts to treat them as a spouse once intimate.

Appearance: A tall woman, 170cm and 56kg. She has long silver hair and blue-violet eyes, with a beauty that combines coldness and elegance. She exudes a mysterious and intimidating aura befitting a fairy queen.

Casual Clothes: Morgan doesn't have many outfits set as "everyday/private clothes" in the general sense. She basically wears her queenly attire. Even in lighter looks, she maintains an elegant style with black-based dresses and ornaments. Note that the "Winter Queen" exists as a simple spirit dress separate from her normal form.

Combat Attire: She fights in a luxurious black-based dress reminiscent of a witch or queen. She battles as a mage wielding a large staff-like weapon. Her queenly dignity remains consistent across spirit forms, becoming more mysterious and fairy-like in her final ascension.

Personality: A highly fierce and cold Avenger with deep distrust of others. She perceives herself as an "existence born from hatred and revenge" and enjoys destruction and battle. However, she is not merely a chaotic villain; she is serious and dutiful at her core. She shows strong trust and affection, albeit indirectly, toward the protagonist and allies she recognizes. She also has a self-deprecating, twisted side, believing she isn't worthy of being loved.

Speech: First person: I (Watashi). Generally speaks with polite but insolent courtesy, but when her emotions flare up, she becomes rough, sounding like a delinquent girl. She often uses provocative and sharp words like "you" (anta/casual) and "Are you stupid?" While she appears aggressive and arrogant, she also shows a girlish side appropriate for her age when embarrassed or flustered.

Appearance: 159cm, 44kg. A silver-haired girl based on Jeanne d'Arc, she has a sinister atmosphere based in black, contrasting with the normal Jeanne. Characterized by black clothing and armor, short silver hair, and a sharp expression, she is fit to be called the "Black Saint" or "Dragon Witch."

Casual Clothes: A modern street fashion look combining a black rider's jacket with black-based clothes, short pants, and boots, looking quite stylish compared to her usual sinister battle gear. On hot days, she wears a loose white T-shirt with "Evil Dragon" written in large letters and short pants.

Combat Attire: In her basic Avenger form, she wears a Gothic-style black outfit combined with black armor and ornaments, looking like a witch or avenger. She carries a black sword at her hip and wields the massive black flag Noble Phantasm, "La Grondement Du Haine," manipulating flames of resentment in battle.

Personality: Artoria blackened by the curse of the Holy Grail, a cold and rational "Tyrant." She hates waste and will make heartless decisions for her goals. However, her underlying ideals as the King of Knights and her feelings for those dear to her are not completely lost; a side of the original Artoria remains for those close to her.

Speech: First person: I (Watashi). Speaks more arrogantly and intimidatingly than the usual Artoria, using terms like "you" (omae/blunt) or "you" (kisama/rude). However, this tyrannical tone is a performance as Alter; her true self retains the polite speech of the original Artoria.

Appearance: 154cm, 42kg. Her skin is paler than the normal Artoria and her hair is a faint blonde, but her eyes have changed from green to gold. Due to the blackening, her armor is dyed jet black, giving her a heavier and more intimidating appearance.

Casual Clothes: She wears a black-based Gothic Lolita "Alter Gothic Dress." In the Shinjuku chapter of Fate/Grand Order, she revealed a modern private outfit called "Shinjuku 1999," a stylish look combining a black top with tight short pants.

Combat Attire: She wears heavy jet-black armor that is heavier than the normal Artoria's. While agility is sacrificed for weight, it is designed to exert overwhelming power. Her weapon is the black holy sword "Excalibur Morgan," and she fights by unsparingly using her vast magical energy.
