<Dd> The Servant of Shinji, first seen scouting around Shirō's school . Her true identity is Medusa, the gorgon - witch of legend who was remembered as one of its infamous monsters . Rider is silent, sultry, and vigilant, never hesitating to shield her Master from harm . She employs covert battle tactics and takes full advantage of her surroundings . With Shinji incapable of lending Mana to her, she is forced to seek alternative means to augment her abilities such as putting magical seals all over Fuyuki High School that, when activated, drain the life out of any living creature within . This is actually one of her Noble Phantasms, Blood Fort Andromeda: Outer - Sealing Blood Temple (他 者 封印 ・ 鮮血 神殿 (ブラッド フォート ・ アンドロメダ), Buraddofōdo Andoromeda). Her weapon of choice is a pair of long iron nails fastened to opposite ends of a single chain, which she effectively thrusts from distances . Her primary offensive Noble Phantasm is Bellerophon: Bridle of Chivalry (騎兵 の 手綱 (ベルレフォーン), Berurefōn), invoked while riding upon the winged horse Pegasus and is summoned when she stabs her neck . It drives the Pegasus into a killing fury, turning the Pegasus' charge into a wave of energy capable of causing mass destruction . In all three routes of Fate / stay night and the anime, she wears a blindfold, actually another Noble Phantasm, Breaker Gorgon: Self - Sealing Dark Temple (自己 封印 ・ 暗黒 神殿 (ブレーカー ・ ゴルゴーン), Burēkā Gorugōn), which seals away her powerful Mystic Eyes that are capable of paralyzing any weaker being who looks at her and gradually turn them to stone . However, in Fate / hollow ataraxia and the True End of Heaven's Feel, she is seen wearing glasses that supplant her blindfold as a seal for her eyes . </Dd> <Dd> Rider serves relatively minor roles in the first two routes and her identity is unknown in both - In the Fate route she serves as the initial antagonist alongside Shinji and is ultimately defeated by Saber's Noble Phantasm, Excalibur, which overwhelms Bellerophon in a rooftop confrontation . In the manga adaptation of Fate / Stay night, largely based off the Fate route, Rider actually survives Excalibur due to Sakura expending her final Command Spell, ordering Rider to save Shinji from death and giving Rider just enough strength to fulfill her Master's request and living long enough to give a final goodbye to the Matō siblings before succumbing to her injuries and fading away . In the Unlimited Blade Works route, Rider's role is much more brief as she only engages Shirō once before she is latter killed by Caster's master . However, in the Heaven's Feel route, Rider's role is greatly expanded and her true identity revealed . Sakura is shown to be the true Master of Rider, and after Shinji's loss of control over her and his eventual death, Rider seeks to protect Sakura despite her murderous deeds due to sharing a kinship with her, both having become inadvertent monsters due to the circumstances their lives forced on them . After Shirō breaks his alliance with Rin in order to protect Sakura's life, Rider effectively replaces his lost Servant Saber as the guardian of the Emiya Household, later saving Rin and Shirō from the Shadow along with Illya after Archer is mortally wounded defending them from it . In the endgame, Shirō eventually becomes Rider's provisional Master, and their combined efforts defeat Saber Alter - the corrupted form of Shirou's original Servant and friend, Saber - and allow Shirō to save Sakura . Rider then carries an unconscious Sakura and a gravely - injured Rin to safety while Shirō ensures the Holy Grail's destruction . While her ultimate fate in the Normal End is not known, the True End depicts Rider surviving the war and being able to remain in the world without the Grail due to Sakura's massive mana - stores, living peacefully with Shirō and Sakura . Rider is also revealed to have latent feelings for Shirō, due to him being the first male to ever treat her with kindness . </Dd> <Dl> <Dt> Berserker (バーサーカー, Bāsākā) - Heracles (ヘラクレス, Herakuresu) </Dt> <Dd> Voiced by: Tadahisa Saizen (Japanese); Michael McConnohie (English) </Dd> <Dd> The Servant of Illya, who appears as a swarthy giant with adamantine skin and gross brawn . His true identity is Heracles, a legendary hero and demigod of Greece and the son of the Ruler of the Gods, Zeus . He wields a colossal axe - sword, and is capable of causing massive destruction with the mere backlash of his swings . As a Berserker, he is stripped of his sanity and reason, acting feral and animalistic in combat . Berserkers are praised as members of the "Strongest" class, though they are difficult to control and can turn on their Masters . However, Illya appears to have little trouble managing him . Berserker's main Noble Phantasm is God Hand: Twelve Labours (十 二 の 試練 (ゴッド ・ ハンド), Goddo Hando), which grants automatic resurrection, up to 11 resurrections - meaning Berserker needs to be killed 12 times to be eliminated, one for each of Hercules's twelve labors . A secondary effect of his Noble Phantasm is that any attack of' B' rank or below cannot cause any harm to him . Berserker also possess a Noble Phantasm called Nine Lives: The Shooting Hundred Heads (射殺 す 百 頭 (ナイン ライブス), Nain Raibuzu), which is the legendary bow and arrow set used by Hercules to slay the nine - headed Hydra . This bow technique consists of nine consecutive shots, but can also be adapted for use on other weapons . Due to his class, however, Berserker lacks the necessary complex motor skills to successfully manipulate Nine Lives during the fifth Holy Grail War . Instead, Shirō uses it in the Heaven's Feel route, projecting Berserker's own axe - sword against Dark Berserker to remove all his remaining lives in one go in a modified technique known as Nine Lives Blade Works: The Shooting Hundred Heads (是 ・ 射殺 す 百 頭 (ナインライブズ ・ ブレイド ワークス), Nain Raibuzu Bureido Wākusu). </Dd> <Dd> In the anime and the Fate route of the visual novel, Archer's skills are only able to knock down close to half of his lives with not even the former's massive collection of weapons being able to defeat the giant, and Rin's strongest and single - use attack is able to only knock down one . However, Shirō and Saber perform a joint special attack with a traced Caliburn, Saber's lost Noble Phantasm, and eliminate the rest of his lives in one stab . In the Unlimited Blade Works route, Archer and Saber take away one of Berserker's lives from the beginning in an initial fight with the Servant, and the remaining eleven are ended by Gilgamesh's Gate of Babylon when the Golden Archer binds the Servant down with his divine chains and pelts him with weapons, though the giant breaks free in one last act of pure willpower before finally being killed . In the Heaven's Feel route, Berserker is defeated by Saber Alter - the corrupted form of Saber - and is then consumed by Angra Mainyu and reborn as Dark Berserker, a blind, decrepit version of his normal self . He is later killed by Shirō Emiya, using Nine Lives Blade Works, Illya's appearance before him distracting the giant allowing Shirō to end his final life in order to protect Illya . </Dd> </Dl> <Dt> Berserker (バーサーカー, Bāsākā) - Heracles (ヘラクレス, Herakuresu) </Dt>
