History FanFic / FateStayNightUltimateMaster

** Caster and Kuzuki too, though it hasn't been shown yet.

* AccidentalPervert: in one scene, Shirou is trying to heal a partially naked Saber from the wound she got following [[spoiler:he battle with Avenger]]. Rin shows up precisely as this point. Guess how she interpret the scene before learning about the wound.

* AlternateContinuity: apparently, this continuity has the Ben 10 universe and the Nasuverse merged as one universe, with interactions mentioned (Shirou did saw pics of Ben’s aliens at school, Illya is a Ben 10 fangirl, Kotomine mentions the Church has been considering recruiting Ben, before deciding he wasn’t easy to control, Rin mentions the Magi Association has been chasing Hex and Charmcaster for their crimes, and Saber met the Forever Knights by the past, who attempted to steal her sword once). For the Route aspect, it includes elements from both all three routes, plus some from Hollow Ateraxia (use of the Avenger class and [[spoiler:Bazett being restaured to life]]).

* BackFromTheDead: [[spoiler:Paradox restaures Bazett to life with her Command Spells back so she can get Lancer back.]]

** Shinji does rape Sakura at one point, but the scene is turned into a DiscretionShot. [[NothingIsScarier This actually makes it creepier]], especially with Zouken’s indifference to it happening.

* GoodAngelBadAngel: an amusing variant; Ben has Gwen’s and Kevin’s voice in his head acting like his good and bad angel, respectively.

*** Used as a RunningGag with Rin each time she gets to see another one of Ben’s alien forms.

* OhCrap: Ben’s reaction when finding out Berserker can handle an Ultimate Cannonbolt charge like nothing. Even more so when he actually read his profile and finds out about his Noble Phantasm.

* CoolShades: Avengers wears these in her civilian attire.

* {{Fanservice}}: Avenger in pajamas after taking a bath. That is all.

The fic is chronologique set after the event of season 1 from the Ultimate Alien perspective, but in an AlternateTimeline of the Fift Holy Grail War from Fate Stay Night perspective. It starts with [[{{Ben10}} Ben Tennyson]] being sent in Japan by the Plumbers to investigate on [[FateZero the murders and unusual events that took place during the Great Fuyuki Fire]]. As he is visiting Fuyuki City, he ends up attacked by Lancer, then looking for souls to feed on. However, as a result of both a latent source of {{Mana}} he got from his Adonyte blood and a mysterious manipulation of the rules by an unknown source, Ben ends up being selected as a Eighth Master, with a female [[FateHollowAteraxia Avenger]] (strongly hinted to be [[spoiler:JoanOfArc]]) as his Servant. Though initially disturbed, he decides to stay in order to ensure the Grail won't fail in wrong hands.

* ThouShallNotKill: Ben is still recovering from his guilt about [[Ben10UltimateAlien almost killing Kevin at the end of season 1]], and as a result is extremely reluctant to rely on lethal method, even in the Holy Grail War. He does compromise with the Servant, considering that since they are doomed to disappear anyway and are aware of the responsibilities, but he still refuses to kill the Masters. Of course, everyone around him other than Shirou find this reasoning foolish and naive.

** Her research on Ben also end up showing a lot of references to previous episodes, including[[Ben10CosmicDestruction Way Big fighting a Black and Blue version of himself in Japan]] and Will Harrangue’s campaign.

* WildCard: Ben is seen as this by everyone else in the Holy Grail War; he is unexpected, overpowered, and his moral code makes him hard to control.

* BerserkButton: Saber ''doesn’t'' take well to be mistaken for Morganna, and even less for a thief who stole Exalibur.

* AdaptationalBadass: [[spoiler:JoanOfArc, compared to her official profile from FateApocrypha. She apparently possess the same profile, but a different Noble Phantasm, “Porteur de Lumière”, that, unlike her official one (“La Pucelle”), doesn’t kill her when she uses it.]]

* When Caster describes the Root of Existance to Ben, this cause him to remember the Forge of Creation.
* Rin mentions [[CarnivalPhantasm not being good with computers and machines]].

!!This fanfic provide exemples of:

* AccidentalPervert: in one scene, Shirou is trying to heal a partially naked Saber from the wound she got following [[spoiler:he battle with Avenger]]. Rin shows up precisely as this point. Guess how she interpret the scene before learning about the wound.
* AdaptationalBadass: [[spoiler:Joan of Arc, compared to her official profile from Fate Apocryphia. She apparently possess the same profile, but a different Noble Phantasm, “Porteur de Lumière”, that, unlike her official one (“La Pucelle”), doesn’t kill her when she uses it.]]
* AlternateContinuity: apparently, this continuity has the Ben 10 universe and the Nasuverse merged as one universe, with interactions mentioned (Shirou did saw pics of Ben’s aliens at school, Illya is a Ben 10 fangirl, Kotomine mentions the Church has been considering recruiting Ben, before deciding he wasn’t easy to control, and Rin mentions the Magi Association has been chasing Hex and Charmcaster for their crimes). For the Route aspect, it includes elements from both all three routes, plus some from Hollow Ateraxia (use of the Avenger class and [[spoiler:Bazett being restaured to life]]).
* AwesomeByAnalysis: after two fight against Ben only, Archer is able to find out his weakness, and even actually succeeds in hurting him. In ‘’Humongousaur’’ form.
* BackFromTheDead: [[spoiler:Paradox restaures Bazett to life with her Command Spells back so she can get Lancer back.]]
* BatmanGambit: aware that she doesn’t stand a chance against a potential alliance of Ben and [[spoiler:Illya]] in a direct fight, Caster relies on this to face them, attacking them with her skeleton familiars, willingly attract Shirou and Rin there, then retreating to leave them fight each other in the hope at least some of them will get killed.
* BattleCouple: Ben and Avenger, though not romantically involved ([[ShipTease yet]]), fit this trope in every other aspects; both are competent in a fight of their own, and each one of them is willing to do everything to protect the other. This actually gets complicated when Avengers gets puzzled about her Master insisting to fight by her side and tries her best to convince him to let her do her job.
* BerserkButton: Saber ‘’doesn’t’’ take well to be mistaken for Morganna, and even less for a thief who stole Exalibur.
** As usual, Ben tends to easily get furious if civilians are put in danger.
* BoringInvincibleHero: subverted; Ben technically overpowers pretty much in the War other than possibly Gilgamesh, and everyone is aware of this, resulting in him being seen as the biggest treath. However, this is balanced by both his usual Ultimatrix glitches and his reluctance to kill both civilians and other Masters, while his opponents make up for it by acting much more [[CombatPragmatism pragmatic]] and [[BatmanGambit smarter]]. Moreover, it has been established that he was not invincible (Archer successfully hurts him durably).
* CallingYourAttacks: since this is the Ultimate Alien Ben, he retains the habit of calling out his aliens’ names. This is actually used against him when Rin uses the names to go in the Internet and find more about him.
* ContinuityNod: a lot to both series involved. Seeing how the story mainly focused on Fate/Stay Night, which always develop the characters’ past a lot, that’s not exactly surprising.
** At the beginning of the first chapter, Ben, while arriving to the city, read his report on the event at Fuyuki City, including a list of all Master in FateZero and the various way their bodies were found.
** Lancer also mentions fighting Saber few minutes before Ben, much like in the actual game;
** while Ben (and later [[spoiler:Paradox]]) are the only characters from Ben 10 to actually show up, Ben has many flashback about both his adventures and his friends; he mentions feeling guilt for almost killing Kevin, and tends to imagine what Gwen and Kevin would say when Avenger tries to sleep in the same bed than him.
* When Caster describes the Root of Existance to Ben, this cause him to remember the Forge of Creation.
* Rin mentions [[CarnivalPhantasm not being good with computers and machines]].
* When looking at the pic of Ben found on the Internet, Shirou notices a pic of [[Ben10CosmicDestruction Way Big fighting a Black and Blue version of himself in Japan]].
* CoolVsAwesome: pretty much any fight involving one of Ben’s alien forms against a Servant.
* ChronicHeroSyndrome: Shirou and Ben, as usual. In Ben’s case, most characters quickly get GenreSavvy enough to attempt to take advantage on it.
* CurbStompBattle: [[spoiler:Ben uses friggin’ ‘’[[AttackOfThe50FootWhatever Way Big]]’’ against Berserker. Guess how that turns out]]
* TheDreaded: a rather toned down and comedic exemple, but Ben tends to raise concern amongst everybody else; his involvement in the war was unexpected by anybody, he has a decently powerful Servant of his own, and he is ‘’himself’’ overpowered thanks to the Ultimatrix. The only one who doesn’t seem concerned with him is Gilgamesh, for [[StoryBreakerPower obvious reasons]].
* {{Expy}}: Avenger, of Saber. Justified, since [[spoiler:he true identity is Joan of Arc, who is indeed similar to Saber in many way in the actual support.]]
* GettingCrapPastTheRadar: the fanfic avoids directly involving sex scenes like one of its original materials, but there are still elements included:
** Shinji does rape Sakura at one point, but the scene is turned into a DiscretionShot. [[NothingIsScarier This actually makes it creepier]], especially with Zouken’s indifference to it happening.
** It’s mentioned that Bazett had been considering “recharging” Lancer’s mana. Everyone familiar with Fate/Stay Night knows what that mean…
* GoodAngelEvilAngel: an amusing variant; Ben has Gwen’s and Kevin’s voice in his head acting like his good and evil angel, respectively.
* IdenticalStranger: Avenger, to Saber. To the point when they fight, Saber actually mistakes her for Mordred.
* NotSoDifferent: Ben and Shirou are much alike in many way; both are in the war solely to ensure the Grail doesn’t fall in wrong hands; both have a huge ChronicHeroSyndrome; and even their Servant are a lot similar both physically and mentally.
* OhCrap: Ben’s reaction when finding out Berserker can handle an Ultimate Cannonbolt charge like nothing. Even more so when he actually read his profile and finds out about his Noble Phantasm.
** Caster has one when [[spoiler:she sees Illya offering an alliance to Ben.]]
*** Used as a RunningGag with Rin each time she gets to see another one of Ben’s alien forms.
* PlayingTheVictimCard: after finding out about Ben’s ChronicHeroSyndrome, Caster decides, rather to fight him again, to confront him in person and tell him about her origin, hoping he will take her in pity and agree to either an alliance or a truth.
* ThouShallNotKill: Ben is still recovering from his guilt about [[Ben10UltimateAlien almost killing Kevin at the end of season 1]], and as a result is extremely reluctant to rely on lethal method, even in the Holy Grail War. He does compromise with the Servant, considering that since they are doomed to disappear anyway and are aware of the responsibilities, but he still refuses to kill the Masters.
* ShipTease: much like Saber, Avenger insists on sleeping in the same room, and even in the same bed, than Ben. The difference is, she succeeds, much to Ben’s embarrassment.
* WildCard: Ben is seen as this by everyone else in the Holy Grail War;
* TheWorfBarrage: poor Lancer gets hit by this [[RunningGag again]] when using Gae Bolg. Using it against [[EnergyBeing NRG]] probably didn’t help.
