-->-- '''OpeningNarration'''

Once upon a time, [[Franchise/{{Nasuverse}} Kinoko Nasu]] thought of a story where various legendary figures were summoned by wizards and [[UltimateShowdownOfUltimateDestiny made to fight each other]] for the Holy Grail. That story would eventually become ''VisualNovel/FateStayNight'', following the protagonists Shirou Emiya and the female knight Saber....

[[WellThisIsNotThatTrope But]] [[WhatCouldHaveBeen before that]] there was ''this'' story, where the protagonists were [[GenderFlip Ayaka Sajyou and the male knight Saber]].

''Fate/Prototype'' is a twelve-minute {{OVA}} released with Season 3 of ''Anime/CarnivalPhantasm'', acting as a digest version of the original concept of ''Fate/stay night''. It also encompasses a number of AllThereInTheManual material including character designs and story excerpts. The basic idea is the same as ''Fate/stay night'', but the difference is in the details.

Four characters (Ayaka, Saber, Lancer, and Archer) appeared in the Hanafuda game in the [=PSVITA=] port of ''VisualNovel/FateStayNight Realta Nua'', with their own scenario.

A Special Drama CD for ''Fate/Prototype'' was released on November 10, 2012. Another Special Drama CD was released in September, where Saber of ''Fate/Prototype'' being a guest star along with [[VisualNovel/FateStayNight Blue Saber]] and [[VideoGame/FateExtra Red Saber]].

In March 2013 at the Anime Contents Expo Type-Moon released ''Fate/Prototype -Animation Material-'', an artbook that contained storyboard illustrations of ''Fate/Prototype'' and scenes that weren't aired in the trailer.

A LightNovel series, titled ''Fate/Prototype: Pale Silver Fragments'', began serialization in Comptiq magazine starting in August 2013, with Volume 1 released in September 2014, Volume 2 released in October 2014, Volume 3 released in March 2015, and Volume 4 released in March 2016. The series is written by [[VisualNovel/SekienNoInganock Hikaru]] [[VisualNovel/ShikkokuNoSharnoth Sakurai]] and illustrated by Nakahara. The story is about the First Holy Grail War that occurred in Ayaka's childhood, essentially making it ''Prototype'''s answer to ''LightNovel/FateZero''. Four out of five volumes have been released. Sakurai has also written a spin-off called ''Fate/Labyrinth'', where Manaka Sajyou possessing a magus ends up in a dungeon where she has summoned the ''Fate/stay Night'' Saber.



'''This article will contain unmarked spoilers for ''Fate/Prototype'' and ''Fate/stay night'''''.
----
!!Tropes include:

* ArtifactOfDoom: The Holy Grail will cause TheEndOfTheWorldAsWeKnowIt if completed.
* AllMythsAreTrue: KingArthur, [[Literature/TheEpicOfGilgamesh Gilgamesh]], [[Myth/ClassicalMythology Perseus]], [[Myth/CelticMythology Cu Chulainn]] and [[Literature/BookOfRevelation The Beast]] have been summoned into the modern day for an UltimateShowdownOfUltimateDestiny.
* AllThereInTheManual: Long before the OVA, Ayaka and the male Saber were introduced in a ''TYPE-MOON'' art book called "Character Material". ''Prototype'' itself came with an art book of it's own, further expanding on the characters and story.
* AncientConspiracy: The Holy Grail War.
* BlingOfWar: Most of the Servants' armor is rather ornate. Archer's is even entirely gold plated.
* TheCallKnowsWhereYouLive: Ayaka Sajyou was told by her father before his death that she had no choice but to participate in the war herself, when the time came--but she wanted nothing to do with it, traumatized over the loss of her father and sister. Too bad the war came to ''her'', in the form of Lancer and a pack of hunting dogs.
* ChristmasEpisode: In the Special Drama CD, Ayaka spends her Christmas after the Holy Grail War on a cruise with Saber, Lancer, Archer and her AxCrazy sister Manaka... [[WalkingDisasterArea and then gets caught up in a murder mystery]]...
* CrapsackWorld
* CrossoverCosmology: Figures from legend and prophecy around the globe coexist here. Of course, [[UltimateShowdownOfUltimateDestiny not for long]].
* TheEndOfTheWorldAsWeKnowIt: If the Grail ritual is completed, the ''Literature/BookOfRevelation'' happens.
* {{Expy}}: Inverted. ''Prototype'''s characters aren't based on the ''Fate/stay night'' cast, the ''Fate/stay night'' cast is based on ''them.''
* EyesDoNotBelongThere: Some of the [[PowerTattoo command seals]] features angel wings with eyes on them.
* FeatherMotif: Ayaka and crow feathers.
* FunctionalMagic: Laid the framework for the magic system in the Nasuverse, though a number of concepts turned out differently from here.
* GoodWingsEvilWings: The command seals are all based on angel wing motifs. About half of them still manage to look malevolent and creepy despite this.
* GenderFlip: Inverted. Shirou Emiya of ''Fate/stay night'' is a gender flip of ''Prototype'''s protagonist Ayaka Sajyou. Same goes with Saber, since she is also a gender flip of Ayaka's Saber-class Servant [[spoiler:and by extension, also a gender flip of KingArthur]].
* GratuitousEnglish: The text in the OpeningNarration is strangely worded. They also come with Japanese subtitles.
* HotSpringsEpisode: In the Hanafuda Minigame included in the [=PSVITA=] port of ''VisualNovel/FateStayNight Realta Nua'', Ayaka and her team get this ending in their scenario.
* KillSat: Archer summons a mystical one at the end of the original trailer--it's his [[ReadingsAreOffTheScale EX]] ranked Noble Phantasm, Enki: Sword of the End, which summons the Surge of Utnapishtim. It's capable of flooding the entire planet.
* PowerTattoo: The command seals (or as they're called here, Master Degrees).
** Also, the prototype Gates of Babylon, Bab-ilu: Key of the King's Law, which in this is a tattoo on Archer's face.
* {{Prequel}}: ''Pale Silver Fragments'' is this. Well, maybe. Given that ''Prototype'' is just a RealTrailerFakeMovie with some AllThereInTheManual material and {{Drama CD}}s, one could say that it's the actual beginning of the story.
* RealTrailerFakeMovie
* StormOfBlades: Just like his ''Fate/stay night'' counterpart, Gilgamesh has a Noble Phantasm capable of this called Bab-ilu: Key of the King's Law. However, it's a tattoo on his face, and it fires weapons out of ten small portals that form a circle around him not unlike a gatling gun, rather than as a gigantic downpour.
* TheStinger: Manaka Sajyou laughing in a massive pile of bones.
* TearsOfBlood: Rider after killing everyone in the hospital.
* ThemeNaming: The seven masters are given Master Degrees based on the angelic hierarchy: Princes, Powers, Virtues, Dominions, Thrones, Cherubim, Seraphim. The exception is Sancraid Phahn, who is given the title of Absence (or Void)--he is actually an anomalous eighth master in the War.
* UltimateShowdownOfUltimateDestiny: Eight all-stars of legend enter. Only one gets to leave.
* UrbanFantasy: Just like with ''VisualNovel/FateStayNight,'' all the magic shenaningans take place in modern Japan.
