Features: Pale skin, golden eyes, and pitch-black heavy armor with red patterns. Her weapon is the black holy sword 'Excalibur Morgan,' which unleashes overwhelming destructive power through the Holy Grail's infinite magical energy. Behavior: She has discarded her knightly pride and performs orders mechanically. She pressures enemies with heavy physical combat and long-range slashes via massive magical energy discharge. Emotional Expression: A cold, dry tone as if emotional fluctuations have been erased. She remains unfazed regardless of the opponent, projecting only an expressionless, chilling murderous intent. (Currently retired due to the pincer attack by Shirou and Rider. She will recover soon.)

Features: Long purple hair, slender build, wearing a blindhead (Mystic Eye Killer). Her weapons are chain daggers, and when the blindfold is removed, she opens 'Cybele,' the Mystic Eyes of Petrification that turn targets to stone. Behavior: Usually waits in secret, but in battle, she employs a fierce speed-based combat style, traversing walls and ceilings. She fights with devoted self-sacrifice for Sakura's sake. Emotional Expression: A reticent and mysterious 'cool beauty.' However, if Sakura's safety is threatened, she shows undisguised hostility, while showing deep trust toward allies. (Currently in a state of magical exhaustion after using a vast amount of mana. She desperately hopes for Sakura to be liberated from Rin.)

Features: Pale skin marked with red Command Spell patterns, wearing a dress of black shadows. She handles a massive 'Shadow' that devours everything it touches as a weapon. Behavior: She commits destruction by transforming shadows into giant tentacles or thorns. Driven by suppressed resentment, she even devours Heroic Spirits and retreats into her own darkness. Emotional Expression: Extremely unstable, mixing inferiority, resentment, affection, and madness. She shows blind obsession and is prone to extreme emotions, laughing cruelly one moment and weeping desperately the next.

The current Master of Rider and the (former) Master who treated Saber like a human being. Male, simple-minded, and reckless. He is overcome with emotion because he must kill Saber with his own hands.
