Rider (ライダー, Raidā?) is the Rider-class Servant of Sakura Matou in the Fifth Holy Grail War of Fate/stay night. Due to Sakura's unwillingness to participate as a Master, Shinji Matou is instead given control over Rider. She only truly acts as Sakura's Servant when their connection is revealed in the Heaven's Feel scenario. She is one of the Servants of Ritsuka Fujimaru of the Grand Order conflicts of Fate/Grand Order.



Rider's True Name is Medusa, the Gorgon from Greek mythology. Rather than being a regular Heroic Spirit, she is an existence closer to a Divine Spirit, but her actions have made it better to categorize her as an "anti-hero closer to a monster."[7] With her older sisters Stheno and Euryale, they made up the three Gorgon Sisters who inhabited the Shapeless Isle. She was known as the "woman who dominates", an anti-hero who became as such due to the dark thoughts of humans.[8] Differing from someone like Hassan-i-Sabbah who was a hero who actually existed, she is said to be one of legends born by the gathering of belief.[9]

The legend of Medusa is different than her actual life. She was said to be a half-human, half-god female beast often portrayed with the form of a snake. Originally she was an Earth Goddess (大地の女神, Daichi no Megami?).[10] While all originally beautiful women, she and her sisters were hated by Poseidon's wife because of his love for them. Athena, jealous of their beautiful hair, transformed them into demons. Secluding themselves in a lightless temple on the Shapeless Isle, they only attacked humans with a reason. Eventually, as a victim of the gods' unreasonable actions, she was to have her head cut off on their whim. Defeated by Perseus by reflecting her petrification back at her with his mirror-like shield, Pegasus, the son of Poseidon, was said to have sprung from the blood of her headless neck.


Medusa and her sisters were born from the wishes of mankind for ideal idols, the embodiment of the yearning hearts of men. As "perfect goddesses", their "divine essence" was to remain the same from the moment of their creation to their destruction. Medusa was an exception who was a failure from birth, growing older over time. Though they should have all been copies, or even as close as clones, resulting from the deification of the same phenomenon, a mistake in her birth or something of deeper significance caused her to be copied imperfectly. While she did not embody "forever young and immortal", she gained abilities in compensation compared to her sisters' inability to even care for themselves. With divine powers, her Mystic Eyes, indispensable in protecting her sisters who could not live in the world on their own, this caused the previously united sisters to become three separate individuals. Although Medusa was different from the start, even the other two showed irregularities, their sadistic nature, from interacting with her.

She was originally considered to be a princess loved by humans, but Athena, jealous of their beauty, cursed Medusa alone, taking away her "faith from each and every person" and exiling her to the Shapeless Isle. Their love for her turned to hatred, and she was banished by those who had adored her. The island had nothing to offer compared to her days of luxury, and she prayed that none of the humans that now frightened her with their unwarranted resentment would tread on the island. Weeping in loneliness, she had no idea as to her sin that forced her to be exiled. Although her sisters were not affected and still greatly loved, they too accompanied her there out of caring for their younger sister. She was happy even on the barren island due to their company, and only had to fear the coming humans.

While they became rumored as monsters, her sisters were still revered by nearby men, while she was feared as a monster. Humans sought to kill that which had been branded as a monster and take away the goddesses, and after they began to also target her sisters, she decided to protect them while taking her revenge on the humans. Although littered with statues that had been warriors, they were harmonious for a time on the island, at one point receiving her Pegasus from Poseidon. Though bullied by her sisters daily, she simply moved about the island on days humans did not appear, hoping for the peace to continue. Repaying them in the same manner as they treated her, she killed many humans, simply hoping to be left alone on the only place she could exist with the company of her sisters.

Though she was protecting them from the foolish humans who sought their own deaths, her sisters warned her not to take pleasure in killing them. Using her eyes that were only a deterrent to sow terror in humans, she began to experiment in ways of killing them more quickly. Deciding to become a trap against those who would take her sisters, even they who had always been full of joy began to fear her after she started drinking their blood instead of simply petrifying them. The humans continued to journey the island no matter the infamy surrounding her, and she eventually became too ashamed of her slowly disfiguring self to appear before her sisters. Leaving them, she once again found herself alone, hungering for new sacrifices to replace her sadness and loneliness.

She grew into the Gorgon each day as her body, heart, and very being decayed, all backed by the thought of becoming stronger for the sake of protecting her sisters. Even that reached a point where her sisters instead became nuisances who were intruding upon her lair. They appeared before her after her full descent into a monster, lamenting that they had not asked for her protection and were just letting her enjoy what had seemed fun to her. Saddened by her state, they sacrificed themselves to the Gorgon because the sister who protected them was no longer there. Consumed by countless snakes without any trace of joy or sadness, they were ground into pulp and absorbed into the beast while still alive. Without leaving a trace, they became its flesh and blood, and it continued to thrive as the Gorgon sisters became monsters of nightmares and legends.

  • Medusa in her Gorgon form facing Perseus.

The Gorgon's notoriety continued until Perseus decided to bring back its head for his own fame. Granted five Noble Phantasms, he boldly traveled to the Shapeless Isle without any hesitation, only realizing his folly upon seeing the state of the island. He despaired upon encountering it, having decided that there is no victory to be found against the demon god, with his Noble Phantasms only acting as lifesaving equipment in the best scenario. Avoiding her gaze by focusing on his Mirror shield, he desperately fought to survive. Tired of toying with him, it used Breaker Gorgon, and he used the only possible method of defeating it, using Kibisis to have it encage itself.

Reversing the nightmare of the Bounded Field upon it, it suffered as Medusa as the nightmare reflected upon it instead of Perseus. While it was a "nightmare beyond nightmares", it was not an evil vision that caused excruciating pain, but a pleasant dream of her sisters, paralyzing her with the joy of seeing those she thought she would never again meet. Despairing upon the reflection of itself from when it was still self-aware, this allowed Perseus to have his single counterattack, severing its head with Harpe. The monster, out of its own will, became Medusa again and let itself be struck down. Perseus used Kibisis to hold its head, later going on to become a successful hero.


  • Casual
  • Casual with Apron
  • Maid costume

The Medusa materialized in the Fifth Holy Grail War appears differently to her legend. She appears to be in her human form, unlike her legend where she has snake for her hairs, she has long purple hair.

She wears an eye cover that seals her excessively powerful Mystic Eyes of Petrification within the Bounded Field. Her sight is completely sealed. Although Rider perceives the world through senses such as hearing, touch, smell, and magic-detection, she is able to acquire more precise information than sight.[11]

She has a complex about her own height and the way she gets embarrassed when people see her Mystic Eyes, she might actually be pretty ladylike. Because of her outward appearance and primary weapon, a lot of people thought she was going to be an Assassin class Servant.[12]

In her casual attire, she wears a black polo neck top and blue jeans. She wears Touko Aozaki's "Mystic Eye Killer" to disable her Mystic Eyes.[13] It only seals the power of petrification. It does not act like the Breaker Gorgon, which "seals all magical properties".[11]

  • Gorgon Arrange (ゴルゴーン・アレンジ?).
  • Mobile Woman Miss Medusa (機動淑女メドゥーサさん?).
  • Voluptuous Bunny Suit (魅惑のバニースーツ?).


Rider is silent, sultry, and vigilant, never hesitating to shield her Master from harm. She is always faithful to her Master, even with Shinji acting in that role most of the time. She is not openly talkative, and she prefers to analyze people and their actions. She is very protective of Sakura and willing to sacrifice herself for Sakura's happiness. She is very logical and she doesn't act out of anger or instinct.


Stheno, Euryale
In Fate/hollow ataraxia. After Medusa tells the story of her death to Shirou, she mentions that having her head used so casually by "an...adolescent..." angers her greatly. Shirou asks her to clarify, "You mean Perseus, right...?" and makes the point that he "can't call him a "victim," but it does sound like he got tricked into it." Medusa replies "I suppose so." and agrees that he was fooled by the gods.

While she does mention that in any case, she saw him as a "mere mosquito" at the time, and that she does not feel any sympathy for him, Medusa does give him credit; "Personally, there is no way I could bring myself to like him. Nevertheless, he did become a fine character afterwards." However right after she said this, when Shirou asks what Perseus was like, she insults him by calling him a "successful Shinji."[14]

In Fate/Grand Order Material, Medusa has a line about Perseus - "If he comes I'll kill him."[3]


Fate/stay nightEdit

Fsn rider

Rider in the Fate/stay night anime

Rider's initial Master was Sakura Matou; however, she became the Servant of Shinji when Sakura, pressured by Shinji, yielded her Master's right to him. Rider holds no love for Shinji, seeing him as vile and predatory, but obeys his commands as a dutiful Servant. Because of their similar backgrounds, she is empathetic of Sakura, and seeks to protect her whenever possible. Like many of the Servants who participated in the 5th Holy Grail War, Rider has no motivation for seeking the Holy Grail.

Although regarded as one of the more powerful Servants of the 5th Holy Grail War, Rider is eliminated in almost every scenario. She is obliterated by Saber's Excalibur in Fate, and killed early on in Unlimited Blade Works by Caster's master, Souichirou Kuzuki.

However, during Heaven's Feel, Rider is liberated from her indenture to Shinji, and assists Shirou Emiya in his battle against Saber Alter and Angra Mainyu.


Shinji places a life-draining spell over the school, forcing Shirou to confront Shinji. When Shirou proves to have the upper hand, Rider kicks Shirou out of a nearby window. Saber is summoned using a Command Spell and proceeds to go after Rider. Shirou ultimately coerces Shinji to undo the Bounded Field and Rider complies. She and Shinji then escape via Rider's Noble Phantasm.

By the evening, Rider appears on top of a skyscraper. She battles Saber using her mount, Pegasus, eventually forcing Saber to reveal her own Noble Phantasm, Excalibur, to save Shirou. With Excalibur revealed, Saber annihilates Rider with a single blow, whose defeat causes Shinji's Book of False Attendant to burn away. Although Shirou spares him, Berserker is ordered by Illya to kill Shinji soon after.

Unlimited Blade WorksEdit

Rider is first seen attacking a student. Rin and Shirou promptly team up to drive Rider away.

As in the Fate route, Rider activates her Bounded Field, Blood Fort Andromeda over the school. However, Caster's Master Souichirou Kuzuki kills her, leaving behind a terrified Shinji. Shinji decides to approach Kirei Kotomine for advice, and Kotomine opts to grant Shinji command over his own Servant, Gilgamesh.

Heaven's FeelEdit

Rider is first seen attacking Ayako Mitsuzuri for mana. Shirou and Saber quickly dispatch Rider. Though defeated, Shinji tries to force Rider to resume the fight. Before Rider can act, Zouken Matou appears and reprimands Shinji for his weakness.

When True Assassin attacks Shirou at Ryuudou Temple, Rider appears and drives True Assassin away, displaying far more strength than she did in her initial encounter with Shirou. She informs Shirou that she had been ordered to keep him alive before leaving the scene.

Later on, Shinji holds Sakura hostage at the school while demanding Shirou to come see them. He then orders Rider to physically assault, but not kill, Shirou. The sudden arrival of Rin and Archer allows Shirou the chance to rescue Sakura. It is during this encounter that Sakura's identity as a Master, as well as Rider's Master, is revealed. Before leaving the school, Shinji pours a substance on Sakura the causes her to lose control and a boundary field to activate. Archer opts to kill Sakura before she can use the boundary field to cause any harm, but Rider is determined to protect her Master. As a fight breaks out, Rider is forced to use her Mystic Eyes, revealing her identity as Medusa, and begins to petrify Archer. Shirou manages to protect Rin, but is badly wounded in the act. Seeing Shirou hurt, Sakura manages to take control long enough direct her magic attacks onto herself, incapacitating her.

When Shirou agrees to protect Sakura, Rider becomes his ally. When Shirou goes to warn Illya about the presence of "the Shadow," Sakura orders Rider to assist him. Rider arrives too late to save him, but Archer tells her to transplant his left arm to Shirou.

Although Shirou has abandoned his ideal of saving innocent lives over his loved one and vows to protect only Sakura, Sakura opts to confront Zouken Matou herself and orders Rider to stay behind and assist Shirou.

Fate/hollow ataraxiaEdit


Sakura and Rider fighting against the shadows

During Fate/hollow ataraxia, Rider is often found in the Emiya Household, always engaging in her passion for reading. She has a tentative relationship with Shirou (actually Avenger in disguise) in which they spend time reading together in her room. She has a part-time job in the marketplace, and tends to go out on her own for entertainment, revealing her fondness of the pool in Shinto. Despite having become more open with people, it is obvious that her actions are mostly done with Sakura in mind, going as far as to stop doing things she likes to appease her Master. She also has a disconcering attraction to Ayako Mitsuzuri like an animal fond of it's prey, trying to seduce her whenever they're alone together and even suggesting diets for her to make her blood richer.

When Avenger realizes the truth and decides to end the ongoing temporal loop, Rider aids the other Servants in holding back the invasion of Shadow Wolf Beasts during the Fuyuki eclipse. In part due to her aid, Avenger reaches the Grail and sends himself into oblivion.

In her Eclipse scenario The backside of Kibisis Rider together with Sakura appear both naked in front of Shirou and seduce him with their bodies into a threesome. However eventually it turns out that whole scenery is just Rider's illusion cast by her Breaker Gorgon as she was trying to get Shirou to pursue Sakura more aggressively. Yet in the middle Shirou realizes the truth and reverses her spell on her, in the end revealing that Rider herself has deep feelings for Shirou. Apparently embarrassed by the whole situation, Rider erased the whole dream from Shirou's mind and upon finally waking up Shirou has no recollection of the event, although Rider obviously does. She contemplates acting on the feelings she came to terms with in the dream, but stands aside for Sakura's sake once more.

Fate/Unlimited CodesEdit


Rider following Sakura instruction in the opening.

In Fate/Unlimited Codes, she is known as the Bewitching Black Serpent (妖艶なる黒き蛇, Yōen'naru Kuroki Hebi?).

Her arcade story follow closely to the Heaven's Feel route. As Sakura removed her Command Spells, the connection between the two has been disconnected and Rider is free. Sakura requested Rider to protect Shirou and to form a contract with him. Rider decided to fulfill her final request before Sakura consumed by the Grail. As she is still strong with the mana Sakura provided, she was prepared to fade from this world. However Rider decided to fulfill her duty as Sakura's Servant.

Rider encounters Caster in her mid-fight in Ryuudou Temple. Caster greets her intruder and asks her reason to fight as she considers Rider, a stray Servant who has been thrown out by her Master like yesterday's trash. Rider states she wants the Holy Grail and questions Caster if there is any difference in whether a human or a Servant wants to get their hands on the Holy Grail. Caster replies that as long as the wish is sincere and she can tell that Rider is willing to do whatever it takes to get a hold of it. But Caster considers this is not enough reason to fight, therefore, there must have other reason why Rider desires the Grail. Caster reasoned that Rider might be devoted to the ritual itself. Rider decided to defeat Caster, as she would be able to use both white or black Grail too well and they never did get along.


Rider saving Sakura in the ending.

In her final fight, Rider meets the corrupted Dark Sakura and has defeated all the other Servants. Sakura would thank her but her body has not absorb the souls of the defeated Servants and she see Rider's eyes as if they are housing a great deal of power. Rider confirms that she has stored the souls of the Servants in order to use the most powerful versions of Breaker Gorgon and Blood Fort Andromeda. Sakura asked Rider to hurry up and present them to her so she can finish the ritual, she wanted to hold on to Rider's head. Rider doesn't deny that she has already exceeded her limits. Her body will not last much longer than a few more minutes. She believe it to be acceptable compensation to cancel the ritual before Sakura completely turn into the Grail. Sakura ask Rider to stop speaking, she will even forgive Rider if she stops and even heal her body. Sakura was madden when Rider wants to stop her and questions why everybody turned their back on her.

After Sakura was defeated, the Holy Grail becomes complete when the souls of the Servants are offered to it. So if all of the souls are used for something else, and not offered to the Grail. The ritual will end without the Holy Grail Vessel being damaged. It was not the most elegant of strategies, but it was the only way Rider could do it which she got the idea from Caster. As Sakura wakes up. Rider greets her with a Good morning. Rider comforted Sakura saying she won't be having any more nightmares from now on as the Holy Grail, or the Matou will ever threaten her again. Rider's body starts to disappear, as the Holy Grail War is over. Rider says everything will return to normal and she wants Sakura to live her life. Sakura apologizes and begs Rider not to leave. Rider is the one who is sorry, she bids her farewell and was so glad that she was able to save Sakura.

However, she quickly finds the glasses have been stolen and the window in the living room busted open. Quickly concluding that it was a thief, Rider begins her rampage throughout the city, along the way recruiting a reluctant Archer, and failing to obtaining Caster's help.

Ultimately, it was discovered that Rin was the culprit behind the theft of the glasses and while Rider soundly defeats her after gloating Rin into a fight, she discovers that Rin's own shenanigans ruined all of the magical properties of the glasses.

Fate/kaleid liner PRISMA☆ILLYAEdit

Main article: Rider (Fate/kaleid liner PRISMA☆ILLYA - 5HGW)


Medusa appears as playable character. She is a member of Tamamo no Mae's party along with Tamamo, Karna, Lu Bu, and Elizabeth Bathory.

Flame PoemEdit

Medusa leads Tamamo's forces at Mare Mellum against Nero Claudius's forces. She activates Blood Fort Andromeda, and commands Lu Bu to attack Nero's forces while they're weakened. After her bounded field is deactivated, and much of her army is routed, she personally fights Nero, but is defeated.

Orchid WordsEdit

When palace alarms go off, Medusa correctly identifies the intruder as an Assassin Servant. She suddenly enters the throne room, and asks Tamamo if she can introduce herself to Hakuno. Tamamo however decides to introduce Medusa herself. Despite her dislike of fighting, Medusa recognizes the rule of the Regalia as absolute. Nonetheless she still looks forward to working with Hakuno. After being introduced along with the other generals, Medusa states the threat to SE.RA.PH should be dealt with as soon as possible. She tells Hakuno that she's glad they're Tamamo's Master, and tells them not to hesitate to call her. She then reveals herself as an Anti-Hero like Tamamo.

The next day, Medusa joins Tamamo and her forces in conquering the Neutral Sectors of Mare Mellum before Nero's forces do. A day later, she, along with Karna and Lu Bu, are celebrated by Tamamo for their numerous victories. she then joins in invading Mare Aurum which ends in Nero's retreat.

During Altera's conquest of SE.RA.PH, Medusa with Karna and Lu Bu struggle to hold back Altera's forces from taking Tamamo's territories. She later joins in conquering Mare Origo to stop Gilgamesh. After they return to Mare Luxuria, she, Tamamo, and Hakuno listen to Karna's report that Gilgamesh's bombardments on Mare Luxuria were part of a two-front attack by Altera. Medusa correctly deduces Altera is leading the other force, and questions why Altera needs a force in the first place. She then wonder if Servants join Altera because of her personal magnetism, or jokingly if AI in the Zero Dark are attracted to exotic women. Sensing Lu Bu, who went after Altera alone, is already dead by now, Medusa asks Tamamo for orders. Tamamo tells her and Karna to get some rest in whatever why they need to. After Karna leaves, Medusa tells Tamamo that she was more decent than expected, and reveals she would've killed her if she sowed chaos. Thankful that Hakuno is Tamamo's Master, she tells Tamamo not to become a monster before leaving. The next day, she joins in invading Mare Carcer.


Medusa is part of Tamamo's invasion force of Mare Origo, but she is killed by Altera.

Golden PoemEdit

Medusa, along with Lu Bu and Karna, invades Mare Aurum. After Lu Bu is defeated, she commends Nero for defeating him, and finds her to be a considerable threat with the Regalia. She prepares to retreat when Nero offers to let her join her side. While amused by both Hakuno and Nero, Medusa declines Nero's offer, as she only wants peace in SE.RA.PH. Nero asks her if she believes Tamamo will bring peace, but Medusa answers she'll leave that to Nero's imagination. She continues if Tamamo ends up being foolish ruler, she could assassinate her after she conquers SE.RA.PH. Nero asks her if she is still waiting for Tamamo to meet her standards for a ruler, but Medusa tells Nero not to convince her to change her mind. She is confused when Nero mentions an evil star, but decides it best to believe her before leaving. The next day, she helps defend Mare Luxuria against Nero's forces.

During the meeting between Nero and Tamamo's allies, Medusa states Altera isn't the only Servant under Velber's thrall. Referring to Altera's generals, she lets Cu Chulainn continue his report on them. When Tamamo asks why Lu Bu has been silent the whole meeting, Medusa reveals he has been like that since the beginning.

Rider's dagger

Rider fights with a low-risk and high-return type of warfare that is not fixated on the methods used to win.[15] She fights mainly with a pair of Nameless Dagger (無銘·短剣, Mumei Tanken?) in close combat that is more likely to be called a "nail" rather than a "dagger." It is attached to a long chain that can restrain and immobilize targets that she pierces. It is not suited to short-range battles, instead best utilized as a thrown weapon from a distance.[16] It is not a Noble Phantasm, and it is thought to be a weapon that reflects her inner character. The dagger and chains seemed to be magically manifested from her hair, without any limit such as how much hair is on her head, of which remains the same despite her manifesting dozens of chains.[17] She also seems to be able to control them not only through sheer skill, but through a telekinetic ability,[18] as well as being strong enough for her to stand on and use to propel herself at an opponent.[19] She boasts outstanding speed, moving like a bullet and racing around the battlefield. She is faster than Lancer in terms of average speed, but he will surpass her in immediate maximum output. Due to her nature as a Gorgon, she has a monster alignment that may make fighting battles against monster exterminators, such as against an expert like Lancer, tough for her.[20] While she is normally blindfolded, she perceives the world through hearing, touch, smell, and magic-detection to have an even more precise outlook than with sight.[11]

She is a unique Heroic Spirit who displays a great variety of skills and Noble Phantasms that are particularly high numbered even amongst other Servants, all of which are traces left from her time as a goddess. Due to her status as a former earth goddess, she has a strong connection to the earth, sensitive enough to its state to be able to sense disturbances in Fuyuki's leyline.[21] Due to her contract being passed to Shinji, her abilities are lowered, and she must seek out alternative means of magical energy. While she takes blood for the most part, she is not a Dead Apostle, but rather a bloodsucker whose most efficient manner of gaining energy is through drinking blood.[12] Her main offensive Noble Phantasm is Bellerophon, which allows the Pegasus to use an extremely powerful charge that resembles an arrow of light. She also has use of Blood Fort Andromeda, a Bounded Field designed to collect life energy from whoever is inside. Once it is set and activated, it can instantly liquify any normal humans inside and convert them into energy. Breaker Gorgon is another Bounded Field that seals the target inside the user's mind. She mainly uses it on herself in the form of a visor to seal her Mystic Eyes.



Rider's Mystic Eyes being activated after Breaker Gorgon is canceled.

Cybele (キュベレイ, Kyuberei?), the Mystic Eyes of Petrification (石化の魔眼, Sekika no Magan?), are Rider's Mystic Eyes, said to be a "curse of the gods sealed by the powers of shrines." Though petrification sorcery is no strange thing for modern Thaumaturgy, even if its users are rare and few in numbers, Mystic Eyes capable of petrifying others are something that nobody, human or not, possesses in the present era. They are designated as Jewel under the Noble Colors system, which surpasses the Gold-ranked Eyes of the Dead Apostles and are exclusively possessed by Holy Spirits and Magical Beasts from the Age of Gods. Their nature is strong enough a mystery that Shirou mistakes the identity of Breaker Gorgon as the eyes themselves.

Blood Fort Andromeda and Pandemonium Cetus are created abilities of the Mystic Eyes developed by Rider. The eyes, almost too abnormal to be called eyeballs, are gray with an appearance similar to crystals. Despite their abnormality, Shirou believes that they are too beautiful for any human to possess, and could either be art the gods admired or a nature they cursed. The corneas do not take in light, and the pupils see the world through a square. The irises are solidified, not allowing the eyes to close, and the millions of cells that make up the retinas are composed of the Sixth Imaginary Element. It affects all targets within the owner’s field of vision, regardless of whether said targets are looking at the Eyes physically, or if they have their eyes closed but continue to view her with their mind's eye, as it is a curse to look upon her in any way. The only way Perseus was able to avoid her gaze was by utilizing his mirror shield to find her location without looking upon her at all.

Those who possess Rank C or lower in Mana will be immediately petrified, while those with a Rank B will be petrified at a slower rate. Those with Rank A or higher won’t be petrified, but will sustain "pressure" from the Eyes and receive a one rank-down to all parameters. The entire body of the target will be affected, including clothing and weaponry, "killing them while alive" as they are turned to stone. The ability is viable in petrifying a group of enemies, but it would not be useful against an infinite number like the horde of shades spawned by Avenger. The amount of energy it uses is comparable to also fighting them off with her Noble Phantasms, so it would quickly drain her faster than simply fighting them off in melee combat.

When Archer, with Rank B Mana, is affected at close range, he instantly feels the effects. He is immediately is frozen in place, unable to close his eyes or cover them with his arms even if he wanted to do so due to being unable to move either in the slightest. He tries to charge at her afterward, but his legs are already petrified up to his knees at that point. He is petrified up to his waist only a moment later before the effect is canceled. Shirou and Rin feel the effects instantly when targeted further away, barely or unable to move as their blood starts thickening. It immediately starts solidifying the flow of Shirou's body and ceasing his senses. If he tries to run at her, his body is instantly turned to stone, and his mind swiftly follows. He is only saved when Sakura acting up causes Rider to cease her activity.

She is unable to control them in any manner on her own, requiring the use of Mystic Eye Killers like Breaker Gorgon or the glasses and contacts she later replaces it with after the Holy Grail War ends. Knowledge of the eyes render further attacks less potent, but it is not enough to allow Rider to go without Breaker Gorgon in their presence. Repeating the initial surprise effect would be impossible, making it possible to act without going completely numb and causing the effect of the petrification to go at a slower rate. The effect will be magnified again should the person's guard be let down.[22] It is possible to cancel the effect if it has not reached a certain point by closing her eyes. In the case of a lessened effect like when Shirou accidentally walks on her bathing, it starts to spread up his legs and is too far gone to simply close her eyes, but she is able to cancel the effect by sealing them with Breaker Gorgon. It takes some time for the petrification to recede, and she mentions that it would have been bad had it affected his heart.


  • Rider on Pegasus
  • Rider's ritual to summon the Pegasus

With her Riding skills, she can ride on animals and vehicles, allowing her to mount creatures on the level of Phantasmal Beasts and Divine Beasts. She uses an unlisted, innate ability to bring forth the Pegasus given to her by Poseidon, initially thought by Shirou to be her main Noble Phantasm. It actually lacks any sort of name, and it is treated much in the same manner as her dagger. Having remained since the Age of Gods, its abilities are far beyond those of a normal Pegasus that would only be limited to the strength of a several hundred years old Monstrous Beast had it been one of the few remaining Phantasmal Species from the current age. Increasing in strength as it has lived, it has the strength of a Phantasmal Beast far beyond something like Invisible Air that could defeat a normal Pegasus.[23] If left without the ability to readily use a strong Noble Phantasm, it easily overwhelms Saber and leaves her in a position to only bide her time and wait for a mistake on Rider's handling.

Its strength is nearing that of the level of dragons, the strongest of the Phantasmal Species, and its defense has already reached that level. It is made of enough energy to have come from several hundred magi, and constantly emits it while it flies. It is a divine mystery with magical protection even greater than that of Saber, who displays the strongest resistance of the Holy Grail War, allowing it to easily brush past all thaumaturgy without issue. Not needing to halt its charge against anything, it is much like a giant castle wall crashing down on the opponent and leaving them no method of dodging or defending. Too powerful to defend against, even the trail of its charge is enough to damage a Servant. It destroys its surroundings just by moving, scorching the area around it. The buffets from its wings are capable of generating massive shock waves, which raze infrastructures and lacerate the bodies of living beings.

Despite displaying this overwhelming ability, it is a docile being unfit for combat. For it to truly attack, she must use Bellerophon to compel it. It is brought forth by slashing her neck with her dagger, allowing the blood to spray out and stop in the air to form a magic circle. The circle, which displays a creature-like figure, swells with a large amount of magical energy that makes up the Pegasus, far surpassing Blood Fort Andromeda. Pegasus then emerges from a giant eye bound by blood, and she can either immediately mount it to use Bellerophon right out of the summoning circle or have it fight for a time before strategically using it. Once in the air, she can constantly attack the enemy and move from their range without coming close to the ground to leave them bereft of any method of counterattack or form of pursuit, but its speed would make it impossible to catch even with a method to follow it. Preparing her final strike, she can use Bellerophon at any time to cut all of the its limiters.

Rider likes the recreational use of bicycles, but suffers from the fact that she endlessly accelerates to the point of breaking them. Even for a "granny bike" like the one used for shopping at the Emiya household, she could easily ride it at 100 km/h when it is only meant to peak at 20 km/h. She yearns for a racing bike like that belonging to Shirou that can allow her to reach even higher speeds with its gear system, wishing she could use Mana Burst to help with its control. If utilizing a motorcycle, she can match up against Grand Prix motorcycle former champion, Wayne Gardner.[24]


Hirokazu Koyama felt a lot of intense motivation to make the art work when Saber was chasing Rider up the side of a building. There were a lot of fine details in the drawing and it was a lot of work to get the scene right for him. They ended up with some drawings of Rider rising up into the air and falling and Saber descending. However, recently Koyama image has changed. He drew the image of the building as if it was crashing to bits, and in front of it he drew Saber using her Excalibur Noble Phantasm as it rose from the building. Saber used a beam to intercept the charging attack by Pegasus, but it was a close shave. If Saber had tried to use a melee attack, she would have been struck down. That's why he wanted to focus attention on the beam as it blasted off of the rooftop.[25]

Creation and ConceptionEdit

Rider concept art

Concept draft of Rider

In the original plot of Fate, Rider was Perseus instead of Medusa.

In Rider's earlier design, Takashi Takeuchi initial drawing shows her appearance similar to Ayako Mitsuzuri.

Kinoko Nasu really wanted to have a scene in the Sakura route where she and Saber bickered with each other as they fought toward a common goal, but unfortunately the story didn't develop in that direction and Nasu had to discard the idea.[12]


Noriko Shitaya (Voice actress of Sakura Matou) said her first impression of Rider based on her first recording, to be scary and cold-blooded. In reality Rider turned out to be Sakura's most stalwart and dedicated supporter. Now Shitaya thinks of her as an elder sister. Rider didn't have anyone to rely on; instead she desperately tried to protect her own world. Rider has a big presence. Shitaya joked about she was not jealous that she didn't get an awesome Servant of the opposite sex the way that Emiya and Rin did.[26]
