History Fanfic / FateHeroAndSword

* ObfuscatingStupidity: Nero, ever ThePerformerKing, deliberately plays up her capabilities as an actress to hide her political talent and combat skill. Archie is left dumbfounded when Nero reveals her true power and takes out a whole group of bandits.

* BonusBoss: Every Servant NPC Shirou made is indicated to be one, as Shirou maxed out their stats and gave them ''ridiculously overpowered'' builds. The developers of YGGDRASIL tolerated this because they were genuinely challenging foes, and modified them to have special drops (Gilgamesh would've dropped a guaranteed World Item if he had ever been defeated, while Medea had a chance to drop Rule Breaker).

* NormalFishInATinyPond: Ainz's thoughts reveal that Nazarick and its [=NPC=]s are this when compared to the Holy City of Camelot -- while the Floor Guardians, Area Guardians, and Pleiades are all more than capable of harrying or defeating a player party, the Holy City of Camelot uses ''[[BonusBoss World Enemies]]'' as their version of Floor Guardians and Area Guardians, which puts them on a completely different caliber compared to Nazarick. It helps that Shirou outright ''cheated'' when making those characters, having used Projection to craft them as opposed to the normal methods available to players.

* AdaptationalExplanation: The fates of the rest of Ainz Ooal Goan are never revealed in canon, aside from one member having been killed in a case of HeKnowsTooMuch. Here, [[spoiler:everyone other than Momonga decided to try one last raid in the Land of Shadows before things ended. This ended in a TotalPartyKill just as the servers shut down, meaning they got sent to the New World inside the Land of Shadows]].

** NPC Gilgamesh's disdain at having to deal with Heteromorphs in YGGDRASIL is in line with his attitude when dealing with Bluebeard's monster in ''LightNovel/FateZero''.

** Merlin attempts to woo Scathach in chapter 3. The exact details are not revealed, but it apparently went so badly that the Witch of Dun Scaith is actively hunting down the Magus of Flowers.

* SitcomArchNemesis: Nero is this to Arturia, as the former looks so much like the King of Knights except for [[BuxomIsBetter having a much more developed bosom]] and [[ShamelessFanserviceGirl showing off way more of her figure]]. The latter makes Arturia unable to stand being around Nero, and [[spoiler:Agravain convinces his king to pretend to be the Valkyrie Knight by making it clear that Nero will fulfil this role if Arturia refuses]].

''Fate: Hero and Sword'' is a fanfic by [[https://www.fanfiction.net/u/6039390/Parcasious Parcasious]]. It is a crossover between ''VisualNovel/FateStayNight'' and ''LightNovel/Overlord2012''.

** [[spoiler:Demiurge's plans involved deliberately using the Fae Bolg Nazaric got off of Cu to bait the rest of Camelot into the field. The reactions that Jaldabaoth gives indicate that Demiurge didn't consider the possibility that Cu's Allie’s would be ''exponentially'' stronger than him]].

* DidntSeeThatComing: Agravain had Mordred be Shirou's guardian during the visit to Northern Roble because he knew that Shirou would not press Mordred for details about her role if she seemed uncomfortable. [[spoiler:Due to Ainz killing Cu, Shirou ends up pressing Mordred for details about Agravain's plans anyway, because things are getting out of hand]].

* YouRemindMeOfX: While she never says anything about it, the first time she meets Merlin, Narbersl notes that he has an aura similar to [[HornyDevils Albedo]]. [[spoiler:This makes her realize that Merlin is a let least part demon]].
