History Characters / FateGrandOrderRulers

* LogicalWeakness: As Moriarty's fate ended in the death of Holmes by the Reichenbach waterfall, Holmes dying by the riverside ultimately screws over Moriarty's WindsOfDestinyChange powers as Moriarty's fate concludes in that moment, and therefore, makes him unable to change his fate from that moment. His profile details how if he hadn't invoked fake to defeat Holmes as if he was the protagonist of a story, Chaldea wouldn't have been able to defeat him.

* {{Foil}}: To his older Archer self, with Holmes noting that Ruler Moriarty is much more reckless and deliberate than Archer Moriarty, which can be evident with their plans within their debut singularities: while Archer Moriarty has a mostly successful plan to outwit Holmes, Ruler Moriarty's plan has cases of DidntThinkThisThrough with Holmes managing to get the last laugh at Ruler Moriarty as the detective's HeroicSacrifice ends up ruining Ruler Moriarty's plan. Additionally, while Archer Moriarty genuinely goes on to view the protagonist as a friend, Ruler Moriarty personally dislikes the protagonist as [[NiceJobBreakingItHero them defeating Goetia caused the Foreign God to descend]].

* HeroicSuicide: [[spoiler:Once he regained his memories that he was a Disciple of the Foreign God, he allowed Moriarty to kill him so that he wouldn't be Chaldea's enemy.]]

[[folder:James Moriarty (Ruler) ("Parting Memories' Manifestation Realm, Traum" Spoilers!)]]

He appears as an antagonist in Lostbelt Chapter 6.5 "Parting Memory Manifestation Realms, Traum".

** He decided to locate his evil lair near a waterfall he named Reichenbach, seemingly so that he can have his rematch against Holmes in the place he first died. What he didn't take into account is how recreating his final battle would affect his ability to weave his own fate if his original fate is retold.

* HoistByHisOwnPetard: If he didn't tell Holmes about the detective being the first Disciple of the Foreign God, Holmes would have ultimately not made a HeroicSacrifice, and therefore wouldn't have left Moriarty to be unable to rewrite his own fate afterwards.
* HopelessBossFight: His initial solo boss fight with Holmes is this as the battle automatically ends at the second turn where Moriarty ends up killing Holmes.

[[folder:Popess Johanna ("Parting Memories' Manifestation Realm, Traum" Spoilers!)]]

First introduced in "Parting Memory Manifestation Realms, Traum" as a Servant accompanying Konstantinos XI, she made her gameplay debut as a Ruler class Servant for the Valentines 2023 event.

* AntiVillain: She's only really a threat in "Parting Memories' Manifestation Realm, Traum" because otherwise she wouldn't exist in Proper Human History. Konstantinos is the primary person pushing for her to be able to be a proper Servant, and she's an ActualPacifist.

* CessationOfExistence: "Parting Memories' Manifestation Realm, Traum" states that, due to being a fictional existence, Johanna is unable to be summoned in Proper Human History normally, a fact that motivates Konstantinos to fight on her behalf. This means that should the Singularity be destroyed, Johanna effectively ceases to exist as a Servant on account of not existing in the Throne of Heroes, which is why Kōnstantînos forms his own faction to ensure she is restored to history. Thankfully, the events of Traum and the FATE system allow her to be summoned as a Servant once again, this time in Chaldea.

* CriticalHitClass: As a unit, Joan's skills focus around buffing Arts Servants, primarily by buffing Arts card absorption and damage while providing crit stars per turn thanks to her first skill. Slap on a CE that provides crit stars per turn, and she can provide at minimum ten stars for the team.

** During the course of "Parting Memory Manifestation Realms, Traum" Moriarty intends to take over Chaldea by force, while Johanna is a NonActionGuy that at most only supports Konstantinos's army with prayers.

* NonActionGuy: In "Parting Memories' Manifestation Realm, Traum", she does not engage in battle directly due to her ActualPacifist beliefs. At best she offers prayers and support to those who follow her, without fighting herself. In gameplay terms, this puts her in a similar role to some of the past Crypters like Pepe, as she buffs the enemy team and supports those around her.

* SpellMyNameWithAnS: Her name has been spelled as both Joan and Johanna.
* StoneWall: Like other Rulers, Joan's stats focus on high HP and low Attack. In her case, she focuses on party support with some damage with her NP.

* SuspiciouslySimilarSubstitute: During the one time she technically is in a battle, she fills a similar role to the Crypters in "Parting Memories' Manifestation Realm, Traum" by being a support character to the enemy Servants during certain boss fights. Like them, she uses Command Seal like skills to buff whoever the player is fighting during select fights, and has a similar portrait setup as a Crypter in battle.

* ManchurianAgent: [[spoiler:Inverted ''and'' defied! Holmes' original role was an apostle of the Foreign God, sent to infiltrate Chaldea to guide them into destroying all the Lostbelts then disposing them aftewards, but Holmes thinks it might have been consensual. He thinks that he himself agreed to help the Foreign God and erased his own memory (and changed himself to a Ruler) to better gain Chaldea's trust. But like Older Moriarty in Shinjuku, he came to truly love his friends at Chaldea. Before his memory came back (and he would truly obey the Foreign God) he let himself get killed by Ruler Moriarty. Sion speculates he defected before sealing his memories rather than the other way around, which the Foreign God allowed because he was still technically fulfilling his orders. But as Chaldea was preparing to destroy the final Lostbelt, the time came for the Foreign God to remind Holmes of his true allegiance and purpose via Moriarty, causing Holmes to commit suicide rather than hurt Chaldea.]]

* TomatoInTheMirror: [[spoiler:He is the '''first Apostle of the Foreign God,''' sent to act as a sleeper agent in Chaldea. His existence caused the Foreign God's home planet to summon Moriarty as its own Apostle to kill Holmes and take over Chaldea.]]
