History HilariousInHindsight / FateGrandOrder

* After Caster Altria’s reveal trailer before she was revealed by name, many fans assumed she was Merlin (Prototype) due to the long-held belief that Merlin (Prototype) would be a Saberface based on their shared voice actors. This was eventually jossed due to the servant being revealed to be Altria from a timeline in which Merlin (Fate/Stay Night version) taught her magic instead, leading to fans being disappointed... that is until Merlin (Prototype) was revealed to be an Arcade unit the very next month, giving her an official design after the years long waiting period. What makes it better is that Caster Altria takes some visual cues from both versions of Merlin (though more obviously the male version), clearly acting as a set up for the eventual reveal.

* Related to the above, but in Caster Altria’s reveal trailer before she was revealed by name, many fans assumed she was Merlin (Prototype) due to the long-held belief that Merlin (Prototype) would be a Saberface based on their shared voice actors.

* Following confirmation that Merlin (Prototype) [[GenderFlip would be female]] and her voiced cameo in Arthur's NP, fans that didn't believe that she would be a Saberface went to work on making fan designs of her, usually depicting her as Merlin with boobs and a similar, [[GenderedOutfit yet feminized outfit]]. Come her [[SuspiciouslySimilarSubstitute design, kit and characterization reveal]] in ''Fate/Grand Order Arcade'', Merlin (Prototype) being Merlin with boobs ended up being a spot on prediction.

* After Merlin (Prototype) was [[GenderFlip confirmed to be female]] and hinted at in Arthur’s NP, fans that didn’t believe she would be a Saberface began drawing fan-designs of her, which mostly depicted her as Merlin with boobs and [[GenderedOutfit a similar but more revealing outfit]]. Her appearance in ''Fate/Grand Order Arcade'' confirmed that Merlin with boobs is essentially what she is.

* Fans had been clamoring for years for a male summer alt as their own unit rather than a Costume Dress option or cameo, and like the girls would hope a fan-favorite recieves the honors. Who broke the barier? The unadvertised second Ascension of Nobukatsu, a Servant that wasn't promoted on his own event's banner, was released in the middle of Fall, and prior to his implementation ''wasn't even playable''. The guy with the least prospects of getting an alt WinsByDoingAbsolutelyNothing.

Who broke the barier? The unadvertised second Ascension of Nobukatsu, a Servant that wasn't promoted on his own event's banner, was released in the middle of Fall, and prior to his implementation ''wasn't even playable''. Can anyone else say "WinsByDoingAbsolutelyNothing"?

* Nobukatsu's second Ascension breaks the trend of male summer alts being restricted to Costume Dress options and cameos, which would be groundbreaking... if Katsu wasn't implemented in the middle of Fall.

* [[HistoricalGenderFlip Minamoto no Raikou as a female]] isn't exactly [[Manga/GetterRobo a first time]] amongst media, but FGO definitely popularized it. Enough that in ''VideoGame/{{Nioh 2}}'', Raikou also appeared ''as a female'', and Kintoki also makes a cameo there.

* [[https://www.youtube.com/watch?v=nMfGiQrxA7Q This fan-made video]] only becomes funnier when you realize that the Avenger-class Servant for the Saber Wars II event is none other than Space Ishtar.

* In ''Capsule Servant'', Jeanne attempts to hijack the narrative of ''F/SN'' and proclaims the "Jeanne boom" to have begun, primarily as a response to Astolfo eclipsing her in popularity for ''Apocrypha''. Cut to ''Grand Order'' where Jeanne has assuredly passed him in popularity as one of the game's poster girls with four different variants. The Jeanne boom has indeed begun. In addition, Rin briefly mistakes Jeanne for Napoleon which later turned out to be ''incredibly'' off-the-mark as far as appearances go.

* ''VideoGame/CapsuleServant'' featured Jeanne as an AttentionWhore who wanted to kickstart the "[[BreakoutCharacter Jeanne Boom]]" and ride on Altria levels of popularity. No less than a year later, she got her wish...but it's Jeanne's own Alter self that helped her popularity along.

* Over the course of the game, EMIYA has gone from [[TierInducedScrappy weak and helpless]] to a highly competent fighter who can tangle with opponents far above his weight class. It's like he's living [[VisualNovel/FateStayNight his teenage years]] all over again!

** The Oniland event itself is an entire send-up of the MagicalGirl genre, ''Franchise/PrettyCure'' in particular. The showcase Servant is Caster-class Shuten-douji, voiced by Creator/AoiYuuki, who at the time of the event, has only voiced ''Anime/KirakiraPrecureALaMode'' [[NonSerialMovie movie]]'s BigBad Cook. Cut to late 2019 a year and few months after the event, Creator/AoiYuuki [[RecastAsARegular finally]] ends up voicing Cure Grace/Nodoka Hanadera, the protagonist of the 2020 entry of ''[=PreCure=]'', ''Anime/HealinGoodPrettyCure''. The Oniland event turned out rather prophetic... And furthermore, Nodoka also has elements of IllGirl and struggles with it, which is ''very'' similar to another Servant played by Creator/AoiYuuki, Okita Souji. [[Memes/FateGrandOrder "Nodoka-san, Daishouri!"?]]

* One Heaven's Feel meme involves photoshopping Saber Alter's face cards into 5 Excalibur Morgans. Altria's 5th Anniversary Rank Up Quest upgrades her Mana Burst skill to give a Buster card boost, NP damage boost, and changes all her current face cards to Buster, making the joke real... for the original Saber, not the Altered version.

* Blackbeard's appearance in the second Summer event has him act as a beauty judge with his verdicts speeding up or slowing down the racers. He gives most of his approval to Teams Satisfaction Ｅ∴Ｔ∴Ｅ and Electric Steam feat. Papa while only criticizing Team Desert Beauty. The third round of the U.S. Server's rerun ended with Desert Beauty ending up in 1st place while Teams Satisfaction Ｅ∴Ｔ∴Ｅ and Electric Steam feat. Papa ended up in the last two positions.

* This is not the [[Series/DaVincisDemons first time]] Creator/LeonardoDaVinci and UsefulNotes/VladTheImpaler being in the same series.

* This isn't the first series that [[WesternAnimation/TimeSquad portrayed Gaius Julius Caeser as fat]]

* The "FBI, open up!", police, and "I'm going to jail" memes involving Illyasviel (and her other versions, ESPECIALLY [[FilleFatale Chloe]]) becomes this after the release of the Second Lostbelt, because you first meet Sitonai (an Alter-Ego using FSN Illyasviel as a vessel)... in a prison cell.

* The Crypters' meeting in the beginning of the first Lostbelt looked kind of normal for its time, with Kirschtaria alone in a room with holograms of the other Crypters. The first Lostbelt was released globally amidst the COVID-19 pandemic in real world where social distancing is highly advised. And thus, the scene became hilarious in a way that while the Crypters are trying to destroy the Proper Human History, [[EvenEvilHasStandards at least they're practicing safety against COVID-19 via social distancing.]] Gets even more meaning when Lostbelt 5.2 was released around the same time frame, [[spoiler:revealing that Kirschtaria was GoodAllAlong, so he looked like he had the social distancing incentive for the safety of everyone right from the start.]]

* While not his first time playing Jekyll, this series isn’t the only time Creator/MamoruMiyano has played [[VideoGame/InazumaEleven a troubled Bishounen with a split personality, one half pure as the driven snow, the other aggressive and brutal]]... it’s just that Hyde can speak coherently and changes minimally this time, making the resemblance between Jekyll/Hyde and Fubuki Shirou/Atsuya much more uncanny. About a year after FGO’s release, the Anime/InazumaElevenAres reboot was announced, where Atsuya [[spoiler:became a part of the permanent cast, giving both updated voices, but as separate people]], and with absolutely no context Jekyll and Hyde wrestling for control sounds almost exactly like the Fubuki [[spoiler:twins]] doing the same, as if he intentionally used the same voices for both.

** Furthermore, years before, someone made an AprilFoolsDay prank about FGO having [[https://www.youtube.com/watch?v=nt0b6d52sHw a crossover]] with ''Anime/MobileSuitGundam''. Then comes [[HumongousMecha Odysseus' NP...]]

* Odysseus' NP becomes this, because in ''Literature/MobileSuitGundamHathawaysFlash'', the rival unit is the Odysseus Gundam equipped with the Penelope Fixed Flight Unit. For even more references, the group fielding the Penelope is known as the Circe Unit.
