History HilariousInHindsight / FateGrandOrder

* 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 barrier? 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.

* When Morgan was first released the fan reaction was originally lookwarm in part to her design being seen as uninspired and it wasn't until later when her full backstory was explained that she became the BreakoutCharacter that she is today. Then interviews about Lostbelt 6 which revealed that the original story plans for Morgan were wildly different but were changed because the design given to her didn't fit with what Nasu imagined Morgan Le Fey to actually look like, revealing that one of her most criticized aspects led to one of her most beloved ones.

* Assassin [[spoiler: Kiritsugu]] was propagated as a possible Servant for several years in fanfiction and fanart, and it's been legitimized in Fate/Accel Zero Order.

* As noted in the "M" folder of the YMMV page, a lot of fans have come to the general consensus that the game's creator is none other than one Kotomine Kirei due to how much the paid gacha favors Black Keys (which are pretty much his signature weapon) and [=CEs=] with him on it. Guess who shows up as a part of the Clock Tower team?

* Another ''Carnival Phantasm''-related matter: Saber Alter Maid is part of the upcoming 2017 Summer event. "I am a cute gothic lolita maid waitress, sir!" Indeed.

* Mara being a gender flip? Not the first time, ''VideoGame/ShinMegamiTenseiStrangeJourney'' has ''Grand Order'' beat by almost a decade. Though that Mara was less...attractive.

* In ''LightNovel/FateApocrypha'', after summoning Mordred, Kairi asks to confirm that she's a Saber-class servant, to which Mordred sarcastically asks if she looks like an Assassin. Kairi then jokingly comments that an armored Assassin with a sword wouldn't be so bad. Fast-forward and we now have the Grand Assassin, King Hassan, who wears a full set of heavy armor and wields a sword.

* The meme calling LightNovel/VioletEvergarden "Violet Sabergarden" due to her resemblance to Altria has now become this, because one, Morgan le Fay's voice actress has been revealed to be Creator/YuiIshikawa; and two, Morgan and Violet both share the same "Saber, but with PTSD" characterization.

* 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!

* Xu Fu gets this because of Manga/BocchiTheRock, because her voice actress portrays the introvert heroine's little sister... who is her complete opposite in demeanor.

** And Mash has been dragged into the VideoGame/MeltyBlood games in return.

** The Oniland event itself is an entire send-up of the MagicalGirl genre, ''Anime/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 the BigBad of the ''Anime/KiraKiraPrecureALaMode''[='s=] [[NonSerialMovie movie]]: Cook. Cut to late 2019 a year and few months after the event, Yuuki [[RecastAsARegular finally]] ends up voicing Cure Grace/Nodoka Hanadera, the protagonist of the 2020 entry: ''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!"?]]

* The introduction of Katsushika Hokusai, actually a ''pair'' of characters featuring Hokusai in an octopus form and his daughter Ou'i wielding a giant paintbrush, was already this trope for ''VideoGame/{{Splatoon}}'', which has a brush weapon called the Hokusai in the Japanese version (Octobrush in other versions). Then ''VideoGame/{{Splatoon 2}}'' later got the ''Octo Expansion'' DLC which allows you to play as an Octoling. And then go into multiplayer as an Octoling wielding the Hokusai, with purple tenta-hair and octopus form if you're lucky.
