The characters of ''Anime/FatePrototype'', [[WhatCouldHaveBeen the original concept of]] ''VisualNovel/FateStayNight'':



[[folder: Ayaka Sajyou]]
!!!Voiced by Creator/KanaHanazawa
The Seventh Master, with the title of Princes. The daughter of a magus, her father and older sister Manaka died in the previous Holy Grail War and she now lives by herself. Suffers from low self-esteem and low talent in her family's magic. Summons the Servant Saber after being attacked by Lancer.

* AnimalMotifs: Crows; in the OVA she's seen attacking with black feathers.
* AdaptationDyeJob: Eye variation from black to blue.
* BigSisterWorship: She admired her sister when she was a young child. [[spoiler:Unfortunately for her, their relationship goes south when Manaka tries to kill her out of jealousy because she happened to have a talk with Saber that results in the latter abandoning his wish for the grail.]]
* BloodMagic: Her father had ordered her to sacrifice an animal each morning. Unable to do so, she uses her own blood as a substitute.
* ButNotTooForeign: It's mentioned in the prequel series that she and Manaka are actually half-British through their mother.
* CainAndAbel: The Abel to Manaka's Cain.
* TheCameo: First appeared in a [[AllThereInTheManual material book]] known as "Character Material", and also made an appearance in a {{Yonkoma}} SpinOff called ''Fate/school life''
* CowardlyLion: Despite seeing herself as weak, she's actually surprisingly strong-willed. Before she accidentally summoned Saber, she was willing to fight to defend herself from Lancer, even if it was ultimately futile.
* DudeMagnet: Something Shirou would [[ChickMagnet definitely inherit]]. She has [[ShipTease moments]] with Saber, Archer, Lancer, and Rider, with Archer being the one who's most blatantly in love with her. Hilariously lampshaded by [[VisualNovel/{{Tsukihime}} Ciel]] much to [[ButtMonkey Satsuki's]] envy in Type-Moon's 2013 April Fools' event.
--> '''Ciel:''' You know she's got herself a harem of not one but three hot guys at her beck and call, right?
--> '''Satsuki:''' [[SeriousBusiness SHE HAS TO DIE.]]
* {{Expy}}: Ayaka basically serves as the basis for the three main Masters of FSN: Shirou, Rin, and Sakura. To wit;
** Much like Shirou, she's the Master of Saber, one of the strongest Servants in the Holy Grail War, who also happened to serve a relative of theirs in the past war. Arthur is also hampered by the fact that Ayaka is one of the weakest Masters, same way how Artoria is hampered by Shirou's own ineptitude as a Master. Outside of their story roles, she's also a specialist type of magus whose talent lies in a field of magecraft that is considered basics for most magi [[note]]Projection for Shirou, Formalcraft for Ayaka[[/note]] and both only really discover said talent through someone spurring them on. [[note]]EMIYA and Arthur respectively[[/note]]
** In regards to Rin, she's the daughter of a magus family that was torn apart thanks to the past Holy Grail War, ending up an orphan as a result and living in BigFancyHouse by herself all the while being acquainted with a Catholic Priest who later turns on her. Physically, she and Rin even look similar to each other. The latter even wears glasses at times, increasing said resemblance. Both also use "magic bullet" like attacks [[note]]Gandr shots for Rin, Black Feathers for Ayaka[[/note]] and live a dual life of being a struggling magus and a student. It's even stated in material that Ayaka's initial relationship with Saber resembles the one Rin would have with Archer. It's also worth noting that both girls are {{Tsundere}} towards their respective love interests, especially when Ayaka's glasses are off.
** As for Sakura, Ayaka happens to be the second daughter of her family much like her and has low self-esteem thanks to her much more talented older sister. Ayaka also gets sick at one point, much like how Sakura gets sick during ''Heaven's Feel''.
** It may be coincidential but appearance-wise Ayaka is similar to [[LightNovel/KaraNoKyoukai Shiki Ryougi]] minus the Mystic Eyes. This beomes more noticeable [[TheGlassesComeOff once she stops wearing glasses]].
* FeatherMotif: Her crow feathers that she used for offensive spells, and that she bears a Command Seal that resembles a single feather.
* ForgottenFirstMeeting: She met and even spoke with Saber during the events of ''Fragments'' but doesn't remember him in the present day.
* FriendToAllLivingThings: She's friendly towards animals. She even befriends and talks to the crows she's supposed to be sacrificing every morning under her father's order, to the point that she's unwilling to kill them.
* TheGlassesComeOff: Whenever Ayaka does this, not only does her appearance change (with her hair and eyes growing brighter as if they were glowing), but her personality will also shift from being her generally weak, and very meek self, to being a more assertive, and outright aggressive person overall, a personality that's reminiscent of Rin's.
* TheGlassesGottaGo: She's noted to be more beautiful when her glasses are off, and her losing her specs is what signifies her [[CharacterDevelopment resolution to willingly fight in the Grail War and to let go of her previous insecurities and weaknesses when she was originally forced into it]]. Interestingly, her personality takes a drastic change whenever she takes them off.
* GreenThumb: To be expected given that she's been taking care of her mother's greenhouse since she was a kid.
* HeroicSelfDeprecation: Has very low self-esteem and thinks of herself as someone plainly average, something she considers as a flaw.
* HiddenBuxom: As seen in Team Prototype's [[HotSpringsEpisode Hanafuda Scenario]] of the 2012 re-release of FSN, Ayaka's clothes do a good job of hiding how secretly [[ stacked she is underneath]]. Her [[AprilFools Chapter Heroine Sanctuary costume]] [[ also speaks for]] [[ itself as well]].
* IJustWantToBeSpecial: She thinks that being average is a flaw. Considering her older sister was an extremely talented magus at a young age, it's not hard to see where she's coming from.
* InnocentBlueEyes: Best shown when she was a [[ChildrenAreInnocent child]] during the events of ''Fragments''.
* LargeHam: In the DramaCD at least, as a consequence of her being the only [[StraightMan straight woman]] there. It must be heard to be believed.
* MagikarpPower: She is unskilled in her family's native magic, but on Saber's suggestion she tries Formalcraft (which she describes as "thaumaturgy for dummies"). She finds that she has a natural talent for it, though what exactly that entails is left unclear.
* {{Meganekko}}: A charmingly pretty girl who uses glasses.
* MinorLivingAlone: Since the rest of her family is dead, she lives by herself.
* OccultBlueEyes: Glasses-off Ayaka is said to be much more powerful and assertive than her regular glasses-on self. In fact, her eyes (along with her hair) basically ''glow brighter'' when the glasses are gone.
* OnlySaneWoman: Poor Ayaka is at her wits' end during the DramaCD.
* ParentalAbandonment: Her father is dead [[spoiler: by the hands of her sister Manaka]], and her mother is mentioned in the prequel novels to have passed away some time after giving birth to Ayaka.
* ShrinkingViolet: She is ''painfully'' shy and lacking in confidence at the start of the story, in a fashion similar to Sakura in the published ''F/SN''. Interestingly enough, in spite of her awkwardness, she ''does'' have friends in school, albeit not ones she could call she's truly close with just like Rin at the start of ''FSN''.
* SurvivorsGuilt: Like Shirou, though how she copes with it differs greatly from his in that Ayaka isn't distorted in any way and that she kept most of her memories [[spoiler: except for ''one'' particularly crucial piece]] of her previous life from before her family's death intact.
* TraumaInducedAmnesia: [[spoiler: Seeing the older sister she deeply admired sacrifice numerous young girls to the Grail as well as murder their own father before her eyes shook her so badly that she erased the memory of the event and most of what happened in ''Fragments'' from her mind. She doesn't even remember Saber, who she's met and spoken to eight years prior. Doesn't help that Manaka also tried to off her too before Saber saved her.]]
* {{Tsundere}}: Towards Saber, but it's more apparent when her glasses are off.
* WorldsMostBeautifulWoman: According to [[LoveAtFirstSight Archer]], who considers her more beautiful than all the women of Uruk.

[[folder: Misaya Reiroukan]]
!!!Voiced by Creator/ChiwaSaito (teenager, OVA), Creator/RuiTanabe (child, ''Fragments of Sky Silver'' Drama CD)

The Second Master, with the title of Cherubim. She is under a curse that eventually takes her life. Her Servant is Lancer.
* {{Curse}}: Was a victim of one as a kid [[spoiler: which is said to come from her father, who casted it while dying ''"Die if you do not become a Master and get the Grail"''.]] [[spoiler: It wasn't that easy: he apparently was mindcontrolled into cursing her, then attempted to undo the curse with no success, and then was killed by the real culprit: Paracelsus, who betrayed the Reiroukans and put the mindcontrol on his master. Misaya later fell victim to it.]]
* DisappearedDad: Her father also was in the last Holy War, and died in it.
* {{Expy}}: While Ayaka is the actual character prototype of Rin Tohsaka, Misaya is the prototype of the ''role'' Rin would later hold - which makes it amusing that Rin was saved by her canon's Lancer. At the same time, her [[spoiler: YourDaysAreNumbered status is seemingly carried over to the eventual fate of Illyasviel von Einzbern (homunculus with a limited lifespan)]].
** She even shares Rin's background as revealed in ''Fragments'': she's a haughty young lady with immense talent whose father was killed and betrayed by someone he trusted, and her mother dies sometime after the previous Grail War before Misaya participated in the next one.
* {{Hellhound}}: Her familiars are black dogs.
* PowerGivesYouWings: Seen with six wings in the OVA.
* TheRival: To Ayaka, [[AllThereInTheManual according to the materials associated with ''Prototype'']].
* {{Sadist}}: She's a noblewoman with a sadistic streak. Her motivation for summoning Cu Chulainn as her choice of Heroic Spirit is fueled by the knowledge that he was defeated by a woman in his lore and wanted to him to know "how scary a woman can be".
--> '''Misaya:''' "I wanted to summon a Hero who was killed by a woman. That way he would know how scary a woman can be."
* SpeaksFluentAnimal: [[AllThereInTheManual According to the manual]].
* UsedToBeASweetKid: When she was just a child back in ''Fragments'', while still bearing the same haughtiness as her older self, Misaya was an innocent and somewhat naive young girl who was kind and trusting towards nearly everybody. [[spoiler: Paracelsus's betrayal of her and her father [[TookALevelInJerkass changed all of that.]]]]
* YouRemindMeOfX: She reminds Lancer of his mentor, [[spoiler:Scathach]]. Likewise, when said mentor became playable in ''VideoGame/FateGrandOrder'', her profile noted that she has a similar demeanor to a certain magus from Tokyo.
* YourDaysAreNumbered: The effects of her curse.
* ZettaiRyouiki: Both in her normal clothes and her school uniform.

[[folder: Sancraid Phahn]]
!!!Voiced by Creator/TakehitoKoyasu

The Absolute Void master, with the title of Absence. Supposedly a member of the Church's Assembly of the 8th Sacrement, he is in fact a member of an organization known as the [[UsefulNotes/TheKnightsTemplar Order of the Templars]] (presumably a splinter group) and is one of their top heretic hunters. His title comes from the fact that he's actually an anomaly in the Holy Grail War, being the eighth Master out of seven. His Servant is Berserker.
* AxCrazy: When he reveals his [[EvilAllAlong true colors]] to Ayaka, his demeanor changes from a somewhat stoic, albeit still sinister, man to an unhinged maniac who constantly screams out loud whenever he's onscreen.
* ChurchMilitant: He's actually not part of the Church, but he still hunts "heretics".
* {{Expy}}: He would eventually evolve into the character of Kirei Kotomine, although "the priest" underwent the heaviest revisions of almost anyone out of the Proto cast on the way to ''F/SN''; Kirei shares very few character elements with Sancraid.
* FauxAffablyEvil: Once he reveals his true colors, he seems rather jovial, but his comments are ''incisively'' hateful.
* LaughingMad: Once he reveals his true intentions.
* NumerologicalMotif: The number 8.
* PoliticallyIncorrectVillain: "I detest Asians, especially the Japanese."
* SinisterMinister: Wouldn't be Kirei's analogue if he weren't this. Unlike Kirei though, he's [[EvilIsHammy much, much less subtle]] about the "sinister" part.
* SlasherSmile: Sports an amazing one during the montage sequence of the extended trailer.

[[folder: Manaka Sajyou]]
!!!Voiced by Creator/AkiToyosaki

The First Master, with the title of Seraphim. The older sister of Ayaka, she had immense talent as a magus, and participated in the previous Holy Grail War eight years ago. Although she was killed during the war, she was resurrected by the Grail. Her prior Servant was Saber, and her current Servant is the Beast.
* {{Adorkable}}: Surprisingly, Manaka can be this as seen during one scene in the prequels where Saber gives her a kiss on the forehead, [[LuminescentBlush to which she reacts with embarrassment befitting a girl her age]].
* AlwaysSomeoneBetter: To Ayaka. Ayaka's inferiority complex in ''Prototype'' stems mostly from Manaka being comparatively more talented and prodigious unlike her.
* TheAntiChrist: Strongly suggested to be one due to being called Potnia Theron, compared to evil dragons, having a Beast related attribute that makes her the master of ''all the Beasts'', and how she plans on bringing about the world Arthur wishes for by using the Beast summoned by the Grail to kill most of humanity.
* AxCrazy: She's an insane and outright ruthless sociopath who would commit any atrocity that would help take her one step closer to fulfilling [[LoveMakesYouEvil her beloved Saber's wish]]. All while enjoying it and wearing a smile on her face even. Her body count in ''Fragments'' is ''huge''.
* BackFromTheDead: After her death at the end of the First War, she somehow revives later on. How exactly has yet to be elaborated upon either, as lore indicates that true resurrection of the dead is near impossible, save for extremely specific circumstances.
* BigBad: She drives forward both the plot of ''Prototype'' and ''Fragments'' and she's responsible for quite a few heinous actions.
* BlueAndOrangeMorality: Sees nothing wrong in [[spoiler: sacrificing her father, Ayaka, and numerous little girls to the Holy Grail in order to power it]]. All for the sake of her achieving her beloved Saber's wish.
* ButNotTooForeign: It's mentioned in the prequel series that she and Ayaka are actually half-British through their mother. This would explain her blonde hair in contrast to both her father and sister.
* CainAndAbel: The Cain to Ayaka's Abel [[spoiler: complete with attempted [[SiblingMurder Sororicide]] in ''Fragments'']].
* CameBackWrong: The twist is that she was already wrong to begin with.
* ChildProdigy: She was only 13-14 during ''Fragments'' but was considered an exceptionally talented magus for her age, with her rank as Master in that War acknowledging this. It's noted that she has an innate connection to [[AkashicRecords the Root]], and that she had few magic circuits in her but they were ''absolutely'' unrivaled in regards to quality.
* CombatTentacles: She can use [[spoiler: the contents of the Greater Grail]] that way.
* CoolBigSis: To Ayaka before her true evil nature and [[LoveMakesYouEvil obsession over Saber]] took over her in ''Fragments''. This trait of hers stays in the DramaCD, but not without a hint of her usual nuttiness to add in the craziness factor happening there.
* TheCorrupter: Being around her can make servants do questionable things or even betray their beliefs. Fragments [[spoiler: Assassin]] and [[spoiler: Caster]] both do things far worse than they normally would do while serving her.
* CreepyBlueEyes: Serves as an evil contrast to her sister's InnocentBlueEyes.
* DoesNotLikeShoes: As seen in the image. Though during ''Fragments'', she does typically wear cute pumps.
* ElegantGothicLolita: Her dress looks a LOT like a Sweet Lolita one.
* EnfantTerrible: She did all her horrible past deeds before turning 14.
* {{Expy}}:
** She was split into Ilya [[note]]older than she looks, pale and cute but still dangerous and with a warped sense of affection[[/note]] and [[spoiler: Dark Sakura]] [[note]](connection to [[spoiler: the Grail]])[[/note]], and some parts of her backstory were incorporated into Kotomine[[note]](being revived [[spoiler: by the Grail]])[[/note]], [[LightNovel/KaraNoKyoukai Ryougi Shiki]] and [[VisualNovel/TsukiHime Aoko Aozaki]] [[note]](innate connection to the Root and having few but super efficient circuits, respectively)[[/note]].
** In a sense, she's also one for Altrouge Brunestud. Both have a "sister" they have a bad relationship with, and both act as the master [[spoiler:of a Beast]].
* EvenEvilHasStandards: [[VideoGame/FateExtra Extra Saber's]] own nutty enthusiasm threw even ''[[TheUnfettered Manaka]]'' off a loop in the ''Extra'' team's ''Hanafuda'' scenario included in ''Fate Stay Night's'' PS Vita port.
* FeminineWomenCanCook: Some time before the Grail War took place, since their mother passed away after Ayaka's birth. From then on, the very girlish Manaka handled most of the housework; she's certainly seen [[ making breakfast]] in some illustrations.
* ForTheEvulz: In ''Fragments'', some of the actions she takes can fall into category due to them having no real motive aside from the fact that she can.
* GigglingVillain: Especially by the time ''Proto'' itself rolls around.
* GoOutWithASmile: [[spoiler:When Saber [[BodyguardBetrayal rebelled against Manaka's orders]] and stabbed her to death in the First War, she couldn't properly process it, and thus died smiling sweetly at him.]]
* ImpossiblyLowNeckline: During ''Fragments'', she wears her dress normally. In the present, she unbuttons her dress and lets it hang past her shoulders.
* InTheBack: How [[spoiler:her Servant]] in the first war killed her.
* LadyAndKnight: She wants to be the Black Lady to Saber's KnightInShiningArmor. '''Badly'''.
* LoveAtFirstSight: Revealed to be the case with her towards Saber. Having foreseen her meeting with him at some point, she held expectations of her ''destined one'' and was more than happy to see that he exceeded them.
** LoveMakesYouEvil: Her meeting Saber is also the reason why she would later go on to commit the atrocities she does in the story. All for the sake of her beloved prince...
* MurderTheHypotenuse: [[spoiler: Just seeing her sister Ayaka speaking to Saber and eventually succeeding in persuading him to let go of his wish towards the Grail was motivation enough for Manaka to attempt to use Ayaka as Grail fuel in ''Fragments''' climax.]]
* NightmareFetishist: What pre-teen/teen girl would describe her love for "her prince" to what she'd feel if her intestines were pulled out of her stomach?
* OlderThanTheyLook: She's six years older than Ayaka, but she still attains her appearance of a 14 year old since she died at that age.
* TheOmnipotent: Referred to as such during ''Fragments''. This is due to her innate connection to the Root since birth, a trait shared only by none other than [[LightNovel/KaraNoKyoukai Ryougi Shiki]], whose third personality is considered to be omnipotent as well. If not due to certain restrictions, Manaka actually has the capacity to grant Saber's wish herself.
* PoweredByAForsakenChild: [[spoiler:Sacrificed girls and her own father to the Holy Grail. She would have sacrificed Ayaka if Saber hadn't stopped her.]]
* PsychicAssistedSuicide: [[spoiler:During the first war, she ''forced'' numerous little girls to sacrifice themselves to the Grail as fuel for it so that she doesn't have to give up Saber himself.]]
* RedBaron: She is referred to as ''Potnia Theron'' by numerous characters due to her powers. Brynhild also refers to her as an Evil Dragon.
* SelfMadeOrphan: [[spoiler:Killed her own father, as said above, and sacrificed him to the Grail.]]
* ShamelessFanserviceGirl: Her standard outfit in ''Proto'' proper is still the same dress she wore during the First War. Only unbuttoned and off the shoulders to reveal her Master Degree of Seraphim on her chest. Convenient angles prevent it from going into full on [[NippledAndDimed exposure]].
** And of course, this also treads into FanDisservice territory, given the aforementioned ''emphasized open wound'' on her chest, which is described as still bleeding, along with her dress being ''drenched in blood''.
* SpellMyNameWithAnS: [[AlternateCharacterReading In Japanese her name can either be read as Manaka or Aika.]] Canon material goes for Manaka.
* SpotOfTea: In the OVA, she and Saber are seen having tea and discussing strategies.
* StartOfDarkness: Before the Holy Grail War, Manaka was a good big sister towards Ayaka and overall a dutiful daughter to her family. The moment she meets and falls in love with Saber however... the results are not pretty.
* SupremeChef: She's her family's main cook after her mother died. She even whipped up a literal feast of delicious food for Saber to eat for breakfast.
* TroublingUnchildlikeBehavior: Her actions and the atrocities she committed during ''Fragments'' after summoning Saber are not things you would expect a young girl of 13-14 to do at her age.
* VillainProtagonist: ''Fragments'' is '''her''' story, in a sense, just like present ''Prototype'' is Ayaka's.
%%* WhamShot: It's very subtle, as it's a regular part of Fate Master design that nobody thinks twice about, but every picture of Manaka as of Prototype's events has had it. [[spoiler: Look at her chest. Her Command Seals are still there -- her Command Seals ''for Arthur''. Even though she died, she never lost them.]]
* WoundThatWillNotHeal: The one on her torso and back. Apparently, ''it still bleeds''.
* {{Yandere}}: For Saber. She was willing to kill her own sister just because Saber had talked with her.
* YouRemindMeOfX: Gilgamesh is disgusted with her because she reminds him of his hated enemy Ishtar.

[[folder: Aro Isemi]]
!!!Voiced by Creator/MegumiOgata
The Third Master, with the Title of Thrones. Isemi is the youngest of the Masters, being just 10 years old.
* EarlyBirdCameo: Briefly appears in the prequel novels [[spoiler:during which he meets the First War's Rider.]]
* GoOutWithASmile: [[ As seen here]].
* IllBoy: [[spoiler: More exactly, [[PlayingwithSyringes the victim of a "chimerization" experiment]] coming after the First War, apparently performed by having Manaka implant a "beast" in his body. By the time he fully summoned Rider, poor Isemi was kept alive solely by medical machinery ''and'' so weakened that he suffered pain from things as normal for us as breathing and his own heartbeat; and lasted only one week before he kicked it.]]
* NiceGuy: That's more or less how he won over Rider's trust and respect. [[spoiler: And as well as the First War's Rider as seen in ''Fragments''.]]
* NoNameGiven: In the OVA at least. A [[AllThereInTheManual fanbook]] later revealed his name to be "Isemi". The prequel novels later reveal that his full name is "Aro Isemi".
* OlderThanTheyLook: Though he's described as looking like a ten year old at best, [[spoiler:Isemi is revealed in ''Fragments'' to have been around long enough that he was considered to be a Master-Candidate for his clan during the First Holy Grail War.]]
* SoleSurvivor: [[spoiler:Of the Isemi Clan that was wiped out by Assassin on the orders from Manaka during ''Fragments''.]]
* TooGoodForThisSinfulEarth: [[spoiler: The kid was ''that'' gentle and ''that'' doomed.]]
* WalkingSpoiler: His existence and fate are tied heavily to Rider's motivations in ''Fate/Prototype''.
* YouRemindMeOfX: He reminds ''Fragments'' Rider of his best friend and foster brother, Moses. They even share the same [[Creator/MegumiOgata VA]] in the [=Drama CDs=].

[[folder: Master of Archer]]
The fifth-Ranked Master with the title of Virtues. A rich business man/magus who owns a skyscraper in Tokyo.
* EarlyBirdCameo: Much like with Isemi, he appears in ''Fragments'' as well. [[spoiler:In which, it's revealed he personally knew Nigel.]]
* Fiction500: He's described as being so filthy rich that he considers classical cars as "chump change".
* IGaveMyWord: [[spoiler:Towards Nigel. Promising to get rid of his body should something happen to him in exchange for information about the Holy Grail War.]]
* NoNameGiven: So far his name has yet to have been revealed.
* PeekABangs: [[ His default hairstyle as seen in material]].

[[folder: Saber (King Arthur)]]
!!!Voiced by Creator/TakahiroSakurai

The Servant of Ayaka Sajyou. A heroic individual with a strong sense of justice. Has made it his mission to protect Ayaka. Was the Servant of Manaka Sajyou in the previous Holy Grail War.
* TheAntiNihilist: Saber is overflowing with hope and determination, and is sworn to fight for protection of the world's future, making him a rather stark contrast than how FSN-Saber was. [[spoiler: He started out much more similarly to her, however, before the young Ayaka made him understand that he didn't need to spend his days mourning his Britain and trying to undo the past.]]
* BadassInDistress: [[spoiler: At some point during ''Prototype'', he's stolen away from Ayaka by Sancraid Phahn and turned into Saber Alter. She later manages to get him back with the help of Lancer.]]
* BlowYouAway: Invisible Air has the ability to do this.
* BodyguardBetrayal: [[spoiler: When he realized Manaka's ''actual'' intentions in the former War, he killed her.]]
* ChickMagnet: He gains the affections of Brynhild, Manaka, and Ayaka.
* DeclarationOfProtection: Not long after Ayaka summons him, he says he'll protect her. [[spoiler: This is actually the ''second'' time he tells her this, however -- and the first time he swore to protect her world on top of it.]]
* DecompositeCharacter: Being ''the'' original concept for Saber, his original Character Material Portrait shows him wearing plated armor, blue clothing and with a white kilt jutting below from it, suggesting where Artoria's look would evolve from, at the same time appearing as a PaletteSwap of what Gilgamesh will eventually wear.
** CompositeCharacter: At the same time, his subsequent iteration in the OVA, shows him heavily armored yet wearing purple-to-dark-blue flowing robes--borrowing a bit from the color scheme of [[LightNovel/FateApocrypha Jeanne d'Arc]].
* {{Expy}}: He's more like Shirou than his female counterpart - he notably ''smiles'' at Ayaka when he's first summoned, and says he's there to protect her.[[note]]Compare the female Saber, who stoically asks Shirou if he is her Master. Significantly, [[AngstWhatAngst he also doesn't seem to have any lingering regrets about his rule of Britain]] unlike the ''VisualNovel/FateStayNight'' Saber, which harkens a lot more from Shirou in the ''Unlimited Blade Works'' route--[[TheAntiNihilist he may be less-naive about the world and heroism, but he holds on to his ideals anyway]]. [[/note]] He also has some traits in common with Archer and his relationship with Ayaka is even described as being similar to that of Rin and Archer - at least at first.
** He also holds shades of Kiritsugu Emiya [[spoiler:as it was his meeting with the young child who would become the next Grail War's "Master of Saber" that saved his heart.]]
* TheGadfly: Apparently a bit, since he is shown stealing Ayaka's glasses with a clear grin on his face despite her protests.
* GodzillaThreshold: Excalibur "Proto" has no actual typing listed in part due to its gradient nature with additional seals released, [[spoiler: but its full power has at best been described as an ''Anti''-Anti-World, being implicitly regarded as a Noble Phantasm that exists to save the planet from threats. It's so immense that the sword's true form in proper continuity has ''never been seen yet'', with Fate/Grand Order cheating this via creative liberties. To wit even Gilgamesh and his Ea analogue of Enki wasn't enough to need it.]]
* TheHero: Taking aside Manaka who's more of a VillainProtagonist, he's more or less the main character of Fragments and is quite heroic.
* IAmNotLeftHanded: Excalibur-''Proto'' differs in what we eventually get in that there are 13 restraining seals to its full powers[[note]]in reference to the 13 Knights of the Round Table, Arthur himself included[[/note]]. To see more, see PowerLimiter below.
* TheIdealist: His wish for the Holy Grail is [[spoiler: or rather, ''was'']] to create a kingdom of everlasting peace, where people no longer need to suffer. [[spoiler: Even when that wish is broken and he must accept he can never make it come true, he still believes in his dream, putting his faith in the future instead of the past.]] Sound familiar?[[note]]This is almost note-for-note the ideal of [[Characters/FateStayNightHumans Shirou Emiya]], who in personality Arthur all but outright ''is''.[[/note]]
* IdiotHair: Not immediately noticeable compared to Artoria's, but it's there.
* InTheHood: His Servant attire features one. Most notably he puts it on when he [[spoiler: killed Manaka and unleashes Excalibur-Proto on the partially awakened Beast of Revelation at the end of Fragments]].
* KnightInShiningArmor: Particularly for Ayaka.
* PowerLimiter: Excalibur-Proto's power is restrained by Thirteen Seals. Over seven of them need to be lifted before it can unleash an Anti-Fortress level attack properly. Though it's revealed in the prequels that with just a few released Arthur can still utilize its power to varying degrees. In Fragments, one was enough [[spoiler: to defeat the Sword of Paracelsus, an ''A+'' Anti-Army Noble Phantasm, with another seal enough to undo its power snatching ability. And six seals released were enough to deal with the Beast during the finale]]. These are the conditions that have been revealed so far, each set by a member of the Round Table including Arthur himself:
** ''"The battle must be an honorable one."'' - ???[[note]]''Fate/Grand Order'' implies this might be Gareth[[/note]]
** ''"Thou must be fighting someone stronger than yourself."'' - Bedivere
** ''"Thou must be fighting one on one."'' - Palamedes.
** ''"Thou must not be fighting against an Elemental."'' - Lancelot.
** ''"Thou must be fighting against evil."'' - Mordred.
** ''"Thou must be fighting without self-interest."'' - Galahad.
** ''"Thou must be fighting to save the world."'' - Arthur.
* RazorWind: Invisible Air, the very same one that Artoria would use herself.
* SetRightWhatOnceWentWrong: Much like [[VisualNovel/FateStayNight Artoria]], Saber desires to save Britain. But as revealed in the prequel novels, the way he goes about it actually helps differentiate the two. Whereas Artoria initially wishes to redo her rule and later changes it to wishing someone else had become King, Arthur desires to create "an eternal kingdom of peace where the people no longer have to suffer". [[spoiler: After meeting the young Ayaka in Fragments, however, Arthur decides to abandon the idea of changing the past, and work to protect the world in the here and now, that it may one day become the kind of world he dreamed of.]]
* SuperpoweredEvilSide: [[spoiler: As some point he would be corrupted by Sancraid Phahn when he steals Ayaka's Command Seal, becoming the prototype to Saber Alter and serving as the base for FSN-Gilgamesh's personality.]]
* TookALevelInJerkass: A mild example, but [[spoiler: having to slay his dearly-held Master last war]] ''really'' did not sit well for Saber, turning him into a similar kind of nihilist to Archer EMIYA. However, [[spoiler: much like the first time,]] Ayaka mends his heart.
** [[spoiler: This occurs again when, under Phahn's twisted arts, he becomes Saber Alter. Specifically, it's been stated his personality became much like what later was reintroduced as ''FSN-Gilgamesh's''.]]
* UnwittingInstigatorOfDoom: Though it's not really his fault, Manaka falling in love with him is what sets off her StartOfDarkness which in turn drives the overall main plot of both ''Fate/Prototype'' and ''Fragments''.
* WaistcoatOfStyle: As Manaka's Servant, he wore a black vest with his [[BadassInANiceSuit dark suit]] in the Spin-off Novel--something [[BadassInANiceSuit Saber herself would similarly do]] in the [[LightNovel/FateZero Fourth Holy Grail War]]. This contrasts with him wearing rather informal civilian clothing as Ayaka's Servant.
* WaveMotionSword: It wouldn't be King Arthur without ''[[PunctuatedForEmphasis EX...]] [[CallingYourAttacks CALIBUUUURRRRR]]!!!'' Based on the OVA, this Saber's Excalibur is way more powerful than what we eventually get, considering it seemingly levels an entire city block in its wake, which is stated to have been at half power. His is also EX ranked compared to Artoria's A++ rank.
* WorfHadTheFlu: Throughout ''Fragments'', he is never in a position for at least seven of Excalibur's restraints to be unsealed and is thus unable to demonstrate its full power. While he can still use its Anti-Fortress attack as long as one seal is removed, the attack will still be weakened and thus in a position to be overpowered (like against Ozymandias' Dendara Light). [[spoiler:Even against Beast VI, Arthur is only able to remove six seals instead of seven, and he was honestly lucky that Beast VI was also in a weakened state.]]
* WouldHitAGirl: He has no qualms about hitting the opposite sex. [[spoiler:In the prequels, he's responsible for taking out both Lancer and Assassin, the only two female Servants in the First Holy Grail War, as well as having no problems stabbing Manaka from behind after discovering the true nature of the Holy Grail and what she plans on doing with it]].

[[folder: Archer (Gilgamesh)]]
!!!Voiced by Creator/YuuichiNakamura

The Servant of the Fifth Master, he is interested in proving himself the strongest and battling other heroes. Acts as a rival to Saber and is smitten with Ayaka.
* AdaptationalBadass: [[InvertedTrope Somewhat inverted]]. When compared to FSN-Gilgamesh, Proto-Gilgamesh actually takes part in actual physical combat a lot more ala EMIYA with his wielding of dual swords. This prevents him from becoming easy pickings for anyone daring enough to actually challenge him up close when compared to his counterpart who simply prefers to shoot his opponents whom he sees as beneath him most of the time.
* BadassBoast: Declares himself the most powerful hero in existence during the OVA.
* BlingOfWar: [[WalkingShirtlessScene While exposing his top]], Proto-Gilgamesh's Servant attire actually comes off as just as fancy, if not even more so, than FSN-Gilgamesh by being more intricately designed in comparison.
* BloodKnight: In comparison to his FSN-Gilgamesh, he's thrilled at the idea of the Holy Grail War, where various heroes of legend get to do battle against each other for the sake of the ultimate prize.
* {{Expy}}:
** He's essentially a composite of ''two'' Archers from the final work: while he eventually mutated into the Gilgamesh we all know and love, he also has elements of the primary Archer, being a dual-wielder who makes an epic stand against Berserker.
** He also has a bit in common with [[VisualNovel/FateStayNight FSN-Lancer]], being a combat-lover and all.
* FriendlyEnemy: With Saber. If the OVA is any indication, he does seem to conduct himself on equal footing with Saber/King Arthur, in contrast to [[SmugSuper his colossal haughtiness against almost everyone]] in ''F/SN''.
* HyperspaceArsenal: Bab-ilu: Key of the King's Law, allows him to access his endless treasury.
* ImprobableAimingSkills: He's an Archer who's an ''actual'' archer, this go around. His aim's good enough that he can miss the earth-planted Saber's head by mere ''inches'' from the top of a skyscraper -- because he ''deliberately'' intended to miss by that much.
* ItsAllAboutMe: So, Arthur is a man in this iteration, which means Gil isn't going to be infatuated with him. What then draws him to Saber in this instance? Because, despite being ''[[WorldsStrongestMan Gilgamesh]]'', he isn't the top-ranking Heroic Spirit in this world, or even the second; he is the ''third'', behind Arthur and Heracles. Gil isn't taking that sitting down, and so throws down the gauntlet with the Holy Sword Wielder to prove he is the best of them all.
* JerkWithAHeartOfGold: While he's still arrogant and possessive of Ayaka, he gives Saber an elixir that can cure any poison or disease so he can cure Ayaka (not without a fight, because hey, it ''is'' the Holy Grail War and Gil loves fighting Saber, but he's still perfectly willing to part with it ''and'' even if Saber had lost, it's all but certain Archer would've gone and tended to Ayaka anyway) and just in general he seems a lot more sensible than his ''VisualNovel/FateStayNight'' counterpart.
* LargeHam: It wouldn't be Gilgamesh if he wasn't one.
* LoveAtFirstSight: With Ayaka, he claims she's more beautiful than the women of his own kingdom. Unlike his ''VisualNovel/FateStayNight'' counterpart, he doesn't act like Ayaka is a possession, and in fact tries to court her. This is probably why ''F/SN'' Gil is often mentioned as having surprisingly high compatibility with Rin in supplementary materials, and relatedly why Ishtar appears looking like Rin in ''Grand Order'' - it's all echoes of Gil's attraction to Ayaka.
* MadeOfIron: One of his original Noble Phantasms mentioned in material is the ability to "Absolutely Survive". It's currently unknown whether or not he still has this ability in the final product, but it's worth noting that he survives ''getting cleaved in half'' by [[WaveMotionSword Saber's Excalibur]] during their climactic battle against each other. That alone should say something about his durability.
* TheNicknamer: Calls Saber "Holy Sword Wielder".
* NoOneCouldSurviveThat: In the climax of his battle with Saber, the partially-unsealed Excalibur tears through his Enki and carves Gilgamesh himself right down the middle. [[spoiler: Not only does Gilgamesh manage to ''survive'' this, he takes Heracles head-on despite his condition, in what would later become EMIYA's battle against the Berserker in ''VisualNovel/FateStayNight'', killing the "Strongest Hero" and ridding Ayaka and Lancer of their greatest obstacle in saving Arthur from Sancraid Phahn.]]
* OhCrap: His reaction in a nutshell when he realizes that Saber survived his Noble Phantasm being unleashed in the OVA.
* TheRival: Rather than invoked by romantic interest --at least, not but for some small part-- Gilgamesh takes exception to Saber ranking as the greatest player in the Grail War, and seeks to defeat him to prove his superiority.
* StormOfBlades: As to be expected. That said, Gil here doesn't use his HyperspaceArsenal as a crutch in the same way as FSN-Gil, instead preferring to take opponents head-on and using his Bab-ilu as a sidearm rather than a primary means of offense.
* SwissArmyWeapon: Enki, which normally functions as a pair of dual swords and act as a bow when both swords are joined together at the pommel. They can also turn into a pair of Tonfa-Style weapons as revealed in material.
* ReadingsAreOffTheScale: His Noble Phantasm, [[TheGreatFlood ''Enki: Sword of the End'']] is an EX ranked Noble Phantasm capable of flooding the entire world.[[note]] Which is a reference to the [[Literature/TheEpicOfGilgamesh Surge of Utnapishtim]]. This later gives rise to [[InfinityPlusOneSword Ea's]] Enuma Elish attack in ''VisualNovel/FateStayNight'' and ''LightNovel/FateZero'' as an attack capable of destroying the world.[[/note]]

[[folder: Lancer (Cu Chulainn)]]
!!!Voiced by Creator/KazuyaNakai

The Servant of Misaya Reiroukan. Tracks down Ayaka at the beginning of the story, which causes her to summon Saber.
* AdaptationalBadass: If his stats are anything to go by, Proto-Cu is actually stronger than his counterpart was in FSN. Having higher overall strength (''A'' to FSN-Cu's ''B''), agility (''A+'' to FSN-Cu's ''A''), mana (''B'' to FSN-Cu's ''C''), and finally, of all things, higher luck as well (''D'' to FSN-Cu's ''E'').
* AnimalMotif: Of a Hunting Dog much like his counterpart, but he's a bit closer to a wolf (even wears a protective amulet in shape of a wolf's head with a crescent moon in its mouth).
* TheBeastmaster: He has excellent compatibility with the canine familiars that Misaya creates.
* BladeOnAStick: Gae Bolg, which is currently not in use by Lancer apparently due to Misaya's orders.
* ButtMonkey: Much like FSN-Cu, he's treated as such in certain gag scenarios.
* {{Expy}}: Mostly unchanged from his ''VisualNovel/FateStayNight'' counterpart, but he is somewhat a bit similar to Shirou, as he's not mature enough to admit the world’s injustices and the values of good and evil.
* HeelFaceTurn: [[spoiler: Eventually contracts with Ayaka when his Master dies, not unlike how Cu Chulainn eventually chooses to ally with Shirou and Rin after Saber was stolen by Caster/Medea.]]
* OneHitKill: Much like his FSN counterpart, Gae Bolg is still this.
* PunchClockVillain: Despite being sent to assassinate Ayaka, he shows enough respect for her efforts to ward him off with her magic, even commending how old and sophisticated hers is.
* WreckedWeapon: As seen in the OVA, his spear was cut in half by Saber after his summoning quite immediately. The impact is lessened by him later saying it was a hastily-made weapon, since his actual spear, the iconic Gae Bolg, is being hidden somewhere.
* YoungerAndHipper: In a sense. When compared to FSN-Lancer, this version is stated to be somewhat younger in both mind and body.

[[folder: Rider (Perseus)]]
!!!Voiced by Creator/MamoruMiyano

The Servant of the Third Master. A mysterious Servant who wears a mask in battle.
* AntiVillain: Rider took a while to warm up to his kind and apparently unassuming Master Isemi, but ultimately came to care for him. Since [[spoiler: Isemi turned out to be TooGoodForThisSinfulEarth]], now he will do anything to [[spoiler: bring him BackFromTheDead.]]
* {{Bishounen}}: From the tiny bit we get to see of him in the trailer posing as one of Ayaka's classmates. Bonus points for being tall and willowy, too.
* CoolMask: Uses one to conceal his identity. [[spoiler: It also acts a pseudo-Master for him after Isemi's death according to material, which is apparently what allows him to participate in the Holy Grail War.]]
* DavidVsGoliath: Gorgon was something of an EldritchAbomination {{Kaiju}} while Perseus had only five Noble Phantasms to his name (a pair of boots that afforded him speed and flight, a shield that could negate her petrifying gaze and act as a MagicCompass, a mantle that made him temporarily invisible, a sword that would wound her in a way that would negate her ability to heal, and a BagOfHolding that could also create an inverse Bounded Field). Suffice to say, his gifts were of dubious utility against such a behemoth of a foe and he only managed to triumph because he frustrated the beast enough that it was tricked into using Breaker Gorgon, allowing him to use Kibisis to bounce the attack back at her. If the fight had gone any longer, it's likely she would have killed him through sheer attrition and his own dwindling confidence.
* {{Expy}}:
** Rider is a somewhat more complicated example than the other characters listed here, as it is unclear how much of his role in ''Old Fate''[[note]]The original draft for both ''Stay Night'' and ''Prototype'' where his identity was originally Theseus.[[/note]]was preserved in ''Prototype'' and how much of it was taken from FSN-Rider due to his changed identity. What is apparent, however, is that he bares something of a resemblance to Shinji, notably his wavy hair, and how he's apparently someone that Ayaka is personally acquainted with but later ends up fighting during the Holy Grail War. In VisualNovel/FateHollowAtaraxia, Rider called Perseus a successful version of Shinji.
* FakeUltimateHero: He was completely terrified during his battle with Gorgon and only managed to win by turning her own powers against her in a last-minute gamble. He's similarly aware that his heinous acts are unbecoming of the hero everyone believes him to be and that his Master wouldn't want him killing for the sake of his resurrection.
* OffWithHisHead: After he defeated Gorgon, she was reduced to her much more human and vulnerable form of Medusa who was helpless before him. He decapitated her without hesitation.
* MythologyGag: His identity is nothing but this considering that FSN-Rider is none other than Medusa.
* LivingWithTheVillain: He disguises himself as one of Ayaka's classmates.
* SummonMagic: Much like FSN-Rider, one of his Noble Phantasms is summoning a Pegasus.

[[folder: Berserker (Heracles)]]

Sancraid Phahn's eventual Servant. A great hero turned into a maddened killing machine by his class, and attached to a Master all too eager to make use of his killing potential.
* {{Expy}}: Pretty much the Berserker we all came to know from ''F/SN'', with surprisingly little changed about the man himself (even his visual design was pretty much locked down this early on). The main difference lies in his relationship with his Master; Sancraid was going to mostly use him as a fire-and-forget missile (i.e. the same eventual relationship between Kirei and Lancer--particularly in ''Heaven's Feel''), basically, to cause maximum destruction, while Ilya ends up having a much deeper relationship with Berserker.

[[folder: The Beast of Revelation]]
The second Servant of Manaka Sajyou. The embodiment of the sins and desires of humanity, it's materialization is apparently the true purpose of the Holy Grail.
* BlueAndOrangeMorality: As a non-human being that exists to devour others, it has no real concept of good or evil. To it all the sacrifices are simply tasty and delicious food.
* TheDragon: It will serve as this to Manaka once it is summoned.
* EldritchAbomination: Its true form is the red seven headed, ten horned Beast ridden by the golden Whore of Babylon. Its initial form is a sea of black mud that is desperately attempting to give shape to its body, starting with its seven brains and jaws.
* EvenEvilHasLovedOnes: Sees Manaka as its mother, [[spoiler: and flips out when Arthur kills her]].
* EnfanteTerrible: Has a mentality comparable to that of a young child, albeit one that wants to devour humans and spread death.
* {{Expy}}:
** Naturally, this is the character that eventually became Avenger Angra Mainyu. The biggest difference is that the Beast is the intentional product of the Grail, while Avenger corrupting the Grail was wholly unintentional.
** Furthermore, the concept of a "Beast" class which embodied a sin of humanity would lurk in the background of ''Fate'' works for a decade (and is even somewhat there in ''stay night'' and ''Hollow Ataraxia''), before the concept returned in full in ''Fate/Grand Order'', to the point that Proto-Arthur's introduction to that game seems to be hinting at this Beast making an appearance there as well.
** Extra materials for Prototype reveal he's also the prototype for the being known as the Beast IV [[spoiler:Primate Murder and that both rule over primates]]. The biggest differences being that their appearances are not confirmed to be anything alike and that he two represent different sins. Later on however, both FGO and the final volume of Fragments later retcons it into being Beast VI.
* HumanSacrifice: In order for it to fully manifest, seven Heroic Spirits are needed to serve as sacrifices. However, to prevent Arthur from serving as one himself, Manaka opts to use over six hundred people instead as a substitute.
* MadeOfEvil: From the few descriptions we have, it shares this trait with Angra Mainyu of the published ''F/SN''.
* NumberOfTheBeast: This was going to be a factor in some fashion, but it's not totally clear how it would've worked in ''Proto'' proper; in ''Fragments'', between six Servants and six hundred humans being sacrificed to try bringing it into being, the number comes close to appearing but doesn't quite make it.
* SevenDeadlySins: Unlike the normal Evils of Humanity it represents an actual human sin, in this case {{Greed}}.
* TheUnseen: No proper design for it has ever been revealed; it's been vaguely described but never depicted on-camera in any work to date.


!!Masters of ''Fragments of Sky Silver''
[[folder: Tatsumi Kitano (Master of Berserker)]]
!!!Voiced by Creator/AtsushiTamaru (Drama CD)
The Seventh-Ranked Master of Princes. An OrdinaryHighSchoolStudent who gets caught up in the Holy Grail War after accidentally summoning Berserker through one of his grandfather's mementos. Believing in justice, he participates in the war to save Tokyo from the dangers that the Holy Grail War presents to it.
* {{Expy}}: Very clearly of [[VisualNovel/FateStayNight Emiya Shirou]] as a Master who got involved in the Grail War via accidental summoning and has a strong belief in the idea of justice. His reason for participating in the war is basically the same as Shirou's own.
* JusticeWillPrevail: Said to be a "justice attitude person", and seeks to defeat all the magi who control Tokyo by evil ritual magic. [[spoiler:Even as a Zombie this trait of his remains rooted into his being]].
* MagicEye: It's said that Kitano's left eye is actually a kind of ''[[ Mystic Eye]]'', which temporarily paralyzes someone.
* MismatchedEyes: [[ In this picture]]. It's because his left eyes is a Mystic Eye while his other is normal.
* OrdinaryHighSchoolStudent: Described as such. He wasn't even aware of his mystic eye until the war had started.
* NaiveNewcomer: Unlike other masters, Kitano had no idea of what the Holy Grail War even ''was'' before being chosen. [[spoiler: This gets him killed by Hassan of Serenity.]]
* OurZombiesAreDifferent: [[spoiler: He's brought back as a barely sentient corpse by Paracelsus to let Hassan have someone she can touch. He [[MadnessMantra repeats over and over how he doesn't want to kill anyone]].]]

[[folder: Nigel Sayward (Master of Lancer)]]
!!!Voiced by Tomohisa Hashizume (Drama CD)
The Second-Ranked Master of Cherubim. A magus from the Clock Tower. As a result of his research, he was in danger of being assigned as a Sealing Designate by the Association. He takes part in the Holy Grail War in an attempt to win the grail for the Association in exchange for his freedom.
* {{Expy}}: Appearance wise, he looks bit like [[LightNovel/KaraNoKyoukai Araya Souren]].
* FantasticDrug: His main specialty as a magus. They're potent enough that he was about to be warranted a sealing designation had he never decided to take part in the Holy Grail War.
* LovePotion: Able to make one potent enough to even affect a Servant like Lancer. [[spoiler:He uses this to his advantage to help spur her on against Saber as she gets more powerful the more in-love she is with her opponents.]]
* WhatHappenedToTheMouse: His fate after Saber's battle with Lancer is unknown. [[spoiler:It's later revealed during the epilogue that he died, likely at the hands of Manaka as she was one of the last people to meet with him.]]

[[folder: Elsa Saijou (Master of Archer)]]
!!!Voiced by Creator/AyaSuzaki (Drama CD)
The Fifth-Ranked Master of Virtues. A kind young woman who had lost her son less than a year ago before the Holy Grail War occurs. Her wish is "for all mothers and children to be saved."
* CameraFiend: Though not shown in-story, her official job is that of being a camerawoman.
* HairDecorations: She wears a white lace headband
* LadyAndKnight: The Lady to Archer's Knight, indeed.
* MixedAncestry: Part Japanese, part German.
* OutlivingOnesOffspring: Elsa was deeply affected by the death of her son.
* SoleSurvivor: [[spoiler:Not counting Manaka who gets revived later on, Elsa is the only survivor among the seven Masters of the First Holy Grail War.]]
* StepfordSmiler: Described as such, putting on a smiling facade as a way to mask her sadness over her son's death.
* TrademarkFavoriteFood: Beer, [[NationalStereotypes as one can guess.]]
* WarIsHell: Having gone to war torn countries as part of her job, she has nothing but distaste for it.

[[folder: Shizuri Isemi (Master of Rider)]]
!!!Voiced by Motoi Koyanagi (Drama CD)
The Fourth-Ranked Master of Dominion. An elderly gentleman who is the current head of a clan of magi whose magic circuits are slowly dying out. As a result, he and his clansmen have learned how to adapt to modern technologies in compensation for the weakening lineage.
* CoolMask: Wears one [[ here]], when he summons Ramesses/Rider as his Servant.
* GraveRobbing: Rider accuses him of this, as the necklace used to summon him belonged to his wife and which by itself could only be obtained by breaking into her tomb. It's never revealed if he himself actually did this however.
* KilledOffForReal: [[spoiler:By Assassin]].
* SharpDressedMan: As revealed in concept art, he's quite spiffy underneath that coat of his.

[[folder: Mr. Reiroukan (Master of Caster)]]
!!!Voiced by Eiji Itou (Drama CD)
The Third-Ranked Master of Thrones. The father of Misaya.
* {{Expy}}: Of Tokiomi Tohsaka, just like Hiroki Sajyou. [[spoiler: Even down to being betrayed and killed by someone he trusted the most.]]
* InformedAbility: As the third-ranked Master among the seven, he could be considered the third best mage among the lot yet is unable to show off any of his abilities [[spoiler:as Caster betrays him for Manaka]].
* NoNameGiven: His given name is never revealed.
* OffingTheOffspring: Said to have fatally cursed his daughter Misaya. [[spoiler: He didn't. In reality he tried to save her from the curse, but was killed before he could do it.]]
* TheGhost: His physical appearance is never seen throughout the prequels.
* WeHardlyKnewYe: Very little is known about him before he died.

[[folder: Seiji Jinga (Master of Assassin)]]
!!!Voiced by Creator/AtsushiImaruoka (Drama CD)
The Sixth-Ranked Master of Powers.
* LargeHam: As heard during the Drama CD.
* SmallNameBigEgo: Having come from a small time magus family, he was intent on winning the Holy Grail War and making a name for himself but gets offed by Assassin minutes after summoning her.
* WeHardlyKnewYe: Killed off by Assassin right after she had been summoned by him.

!!Servants of ''Fragments of Sky Silver''
[[folder: In General]]
* BackFromTheDead: A natural occurrence in a Holy Grail War setup. [[spoiler: However, later on by the time of the second Holy Grail War, Manaka brings them all back as part of her personal force.]]
* TheBeautifulElite: It's rather notable that when compared to other Grail War settings in the franchise which has at least one unattractive or older looking Servant, every single one of the Fragments Servants, Arthur included, is quite the looker.
* TheCorruption: [[spoiler: As seen in the [[ final illustration]] of the last volume of Fragments, all six of them have been corrupted into Alters by Manaka. Especially notable with Ramesses, as he managed to resist being taken over by a Demon God during the Sixth Singularity of ''Fate/Grand Order''. As with all Alters, they've also become more aggressive in nature which is most notable in [[IdealHero Arash]].]]

[[folder: Lancer (Brynhild)]]
!!!Voiced by Creator/MamikoNoto
The daughter of Odin who became mortal. She fell in love with and killed Sigurd after he lost his memories of her and married her as part of a plan. Her master is Nigel Sayward.
* ActionGirl: Perhaps one of the strongest Servants in the First Holy Grail War. [[{{Yandere}} And she gets stronger the more she loves her opponent]].
* BladeOnAStick: She utilizes a long and gigantic spear with a large blade reminiscent of a shield.
* BornUnlucky: [[RunningGag Much like other Lancers in the franchise]] Brynhild's luck rank is very low. In fact, it tops out at E. Considering what happens to her by the end of ''Fragments'' and afterwards, [[UpToEleven it could even be said that she has ''the worst'' luck among them all]].
* {{BFS}}: Not only is her spear large, it also grows larger and heavier the more she loves her opponent.
* GeometricMagic: She has a powerful Origin Rune upon her chest given by her father Odin. It has enough power to destroy Tokyo.
* ICannotSelfTerminate: [[spoiler:After being hijacked by the world or her father Odin to stop Manaka, she asks Saber to end her life before she kills the people of Tokyo]].
* LightningBruiser: Going from her stats alone she's this and it shows.
* LongHairIsFeminine: She's said to be a woman with "a delicate body and long hair".
* NoSell: Hassan's poison has no effect on her due to her flames being hot enough to burn away the poison.
* ThePowerOfLove: Her Spear Noble Phantasm is powered by love. If she loves something the more powerful it is and more damage it does to the target. She loves almost everything in the world on some level except for [[BigBad Manaka]] and can't harm the evil dragon she sees before her.
* RapunzelHair: Her hair is long enough to reach her thighs.
* SanitySlippage: [[spoiler:Being subjected to Nigel's love potion and her father Odin forcing her to take action against Manaka does a number on her psyche which resulted in her going on rampage. Luckily, she's able to snap out of it long enough to let Saber kill her.]]
* SemiDivine: Being a former goddess, she counts. Though her divinity is ranked at E due to her falling out with her father Odin.
* ManOnFire: She's able to wrap her body in fire.
* WorldsMostBeautifulWoman: Described as being such in the prequel novels.
* {{Yandere}}: One of the first and most famous examples, but also weaponized. Her spear becomes heavier and more powerful the more she loves the target. She loves nature, the world and all people to a certain extent, but against heroes, who can swiftly evoke powerful feelings in her, it becomes extremely powerful. She's basically a Hero-Killer, especially to those who remind of her Sigurd. Arthur in particular evokes it the strongest among the Servants.
* YouGottaHaveBlueHair: Her hair is a teal-colored white.

[[folder: Archer (Arash/Aras-e Kamangir)]]
!!!Voiced by Satoshi Tsuruoka
Arash is a famed bowman sung in Persian myths, who accomplished the great feat of saving thousands of people during battle.

* BashBrothers: With Arthur, particularly when they unite to bring down Ozymandias together.
* HeroicSacrifice: [[spoiler:He uses ''Stella: The Lone Meteor'' to help Saber defeat Rider at the cost of his own life]].
* IdealHero: Arash believes in and follows the path of the ideal hero. He will do whatever he can to protect the people when they are in need even at the cost of his life.
* MadeOfIron: He has A ranked Endurance and the EX ranked Robust Health skill. This is due to being born in the Age of Gods.
* TrademarkFavoriteFood: Another illustration shows them [[ happily drinking beer]] with his Master, Elsa. It includes a bit of FridgeBrilliance: Arash is a hero of Iranian oral tradition and folklore, and beer was already being produced in the lands now occupied by the modern Iran around 3,500 BC.
* TooAwesomeToUse: His Noble Phantasm, the usage of which costs him his life.

[[folder: Rider (Ramesses II/Ozymandias)]]
!!!Voiced by Creator/TakehitoKoyasu
The Egyptian Pharoah commonly associated with [[Literature/TheBible Moses]].

* AlternateHistory: Moses was his best friend. While the events of the Literature/BookOfExodus would still play out (Moses becomes God's prophet and the Ten Plagues are unleashed on Egypt when Ramesses refuses to free the Israelites), the parting of the Red Sea ultimately convinces Ramesses to not pursue Moses and the Israelites. The original story had the Pharaoh and his army chase the Israelites down the open path only to be swallowed by the Red Sea when it closes up.
* TheBeastMaster: He has a palace-like Reality Marble ''filled'' with Phantasmal Beasts of all kinds.
* BerserkButton: He flips his shit upon being summoned due to his catalyst being his wife [[spoiler: Nefertari]]'s necklace, which could have only been obtained by raiding her tomb.
* {{BFG}}: His Ramesseum Tentyris has the ability to utilize the [[ Dendera Light]] as a massive beam cannon capable of flattening cities.
* BloodKnight: His narration points out that he actively forgave and praised warriors with the courage to challenge him during his life, even forgiving them for their rebellion against him if they provided him a good match.
* BreathWeapon: His Sphinx has this in the form of a '''[[PlayingWithFire fire]] [[BlowYouAway tornado]]'''.
* DramaPreservingHandicap: To even make it possible for Saber to defeat Rider, Manaka has his Master's entire clan murdered [[spoiler: with the help of Assassin's poison]]. Rider is still so invincible that [[spoiler: Saber had the full assistance of Lancer, Archer and Caster, and even then only Arash's suicidal Noble Phantasm could even the odds enough for Excalibur to match Ramesses' Dendara Light.]]
* {{Expy}}: Of [[VisualNovel/FateStayNight Gilgamesh]], as he is a Heroic Spirit from a distant time period, having been a ruler in his life, arrogance that belies HiddenDepths, as well as being incredibly powerful.
* InvincibleVillain: Or InvincibleHero rather, given that Manaka is a VillainProtagonist. Manaka holds Rider in such high regard that she believes not even the Three Knight Classes united could bring him down, but has [[{{Yandere}} faith that Saber will pull through regardless]].
* JerkWithAHeartOfGold: If not outright JerkassFacade. He talks a big game and possesses a very high opinion of himself, but he forgives his Master for desecrating his wife's tomb, offers [[spoiler: the Isemi child a MercyKill]] if he should desire so and genuinely wishes to rule the modern world as to bring it into a new golden era. Not for nothing is the line "The Pharaoh's heart is as noble as the sun" used in his first POV sequence.
* LargeHam: He likes talking, that's for sure.
---> Rider: “Hahahahahahahahahahahahahahahahaha! Rejoice in it! Observe it! I will seek it! I have surely remembered your tenacity; there is nothing else in the world which hadn’t change since the world where I also ruled here! I want it! Because, I am the person that is destined to govern this world!”
---> Rider: “Anut and Set, it is good that you dwell in both of my arms! Astarte, wish me well so that the earth will be soaked in the blood of my battles after my glorious victory! I who am Horus and Ra will give happiness to the world when I get another life, from here on! O’ my beloved Nefertari, you will bless the call of Ozymandias as Hathor!”
* MagicKnight: He possesses an abnormal talent in the ways of Magecraft, being able to knock Misaya unconscious by just looking at her Familiar, and uses a crystal orb to view the battle between Saber and his Sphinx from afar. Additionally, he possesses a Reality Marble-like ability.
* MentalWorld: Possibly with Ramesseum Tentyris, which summons a massive amount of great Egyptian temples in a complex spanning miles from end to end. It is noted that many of the temples in it were not build in his lifetime, but as he is the King of Kings, the greatest king of Egypt, he naturally rules over the domain of lesser kings, including their temples.
* MythologyGag: Nasu mentioned that, in his original vision of ''LightNovel/FateZero'', Iskander would have had an arrogant and narcissistic streak not unlike the future [[VideoGame/FateExtra Red Saber]] - however, Creator/GenUrobuchi wrote a far more charismatic version that Nasu liked so much that he shelved his Iskander in favor of Urobuchi's. Given his own temperament as well as the niche of being a powerful Rider-class king, it's easy to say that Ozymandias ''is'' this original vision of Iskander, albeit applied to a different historical figure.
** From his own backstory, his actions of not following Moses into the parted sea call in mind how the scene was handled in Film/TheTenCommandments.
* ThePowerOfTheSun: As "Ra's Mighty Truth", he possesses Ra's almighty solar barge as a Noble Phantasm. It can supposedly reduce all of Tokyo to dust in the span of a couple of hours.
* OddFriendship: Seems to have sort-of struck one [[spoiler: with a boy who is strongly implied to be the Isemi who would become the next Holy War's Master of Rider.]] At very least [[spoiler: the little boy managed to calm Rider down from his anger upon being summoned through Nefertari's necklace, and then he properly joined the Grail War.]]
* ReadingsAreOffTheScale: He possesses an EX-rank in the Noble Phantasm parameter.
* RedBaron: "King of Kings", a title historically attributed to Ozymandias/Ramesses II.
* StoryBreakerPower: To say Ozymandias is the Gilgamesh of the First Grail War would be criminally ''understating'' just how powerful he is. Even on top of Saber-grade Magical Resistance, even on top of B-Rank Divinity, even on top of his Imperial Privilege, even on top of his A+ ''Protection of the Sun God'', he has ''three'' Noble Phantasms and the most powerful of them all is an ''EX-Rank Reality Marble''. That it took Excalibur Proto and Stella to defeat him ''after'' Manaka had his mana supply cut off just further proves how unbelievably strong he is.
* SuperPowerLottery: In addition to his skill Imperial Privilege that lets him obtain any other skill that he should desire, he possesses ''three'' Noble Phantasms, the weakest of which is compared to 3 Servants in strength.
* TwoGuysAndAGirl: Him, [[ Moses, and Nefertari]] were this in the past.
* WalkingShirtlessScene: [[ As seen here]].
