Observer on Timeless Temple and Epic Of Remnant Event Villains
Mysterious creatures who resemble the Demon King of the Sixth Heaven, Oda Nobunaga. They first appeared in GUDAGUDA Honnoji event and have been a mainstay in the following GUDAGUDA events.
- Action Bomb: Good majority of the different Mini Nobu variants have an attack where they charge into the opponent with an explosive hira-gumo tea kettle. They somehow survive the attack.
- Adorable Evil Minion: They are chibified version of Nobunaga who are the main Mooks of the GUDAGUDA events.
- Artificial Human: Maybe. It's not entirely clear how the Mini Nobus were created, aside from Nobunaga claiming they were made from the distilled essence of the final star she needed to become a 5* Servant and kept her at a "mere" 4*. A lot of the latter variants of Nobu definitely are mechanical-looking. A diagram of one in Final Honnouji theorizes that their hats are their real bodies.
- Casting Gag: Played for Laughs in the second part the 3rd GUDAGUDA event, where the seven types of Mini Nobu's fought have the same seiyuus as the class the original seven Servants summoned in Fate/stay night.
- Category Traitor: The Nobusengumi are Mini Nobus that have sided with Okita and the Shinsengumi and wear the group's haori and wield the obligatory katana. Nobunaga considers them traitors to her cause.
- Fighting Clown: Mini Nobus are a parody of a parody character, being chibified version of Nobunaga who can only say out their names and getting wackier alternate versions with each event. That being said, their combat prowess is surprisingly high despite their appearance, especially since they can adapt to various different fighting styles. Their Command Code notes they're actually surprisingly strong and quite relentless in battle despite appearances.
- Flying Saucer: The Nobu UFO are Mini Nobu who ride on hira-gumo tea kettles like they were UFOs. They even have tractor beams.
- Golem: The Haniwa Nobu are haniwa fashioned in the form of a Mini Nobu which have Super Toughness and can trap Servants inside themselves to power up. Considered ridiculous even by the standards of the Mini Nobu, but still a threat especially with the mountain-sized ones.
- Half the Man He Used to Be: Mini Nobus get cut in half whenever they are defeated.
- Not-So-Harmless Villain: In the first two Gudaguda events, they're seen as annoying nuisances at best. Then Gudaguda 3 has them mercilessly and effortlessly gunning down hundreds of defenseless civilians in the streets, all with the same smile and Pokémon Speak they've always had.
- Pokémon Speak: The only thing that they say are "Nobu!" in different tones.
- Robot Me: The Mecha Nobu line are robot Mini Nobu that fire a Breath Weapon, have detachable heads, and extendable claw hands.
- Tank Goodness: Tank Nobu are Guntank-like Mini Nobu that are riding on tank threads and are equipped with hand-mounted miniguns and shoulder-mounted muskets.
- Spell My Name with an S: They are called both "Nobu" and "Nobbu" in the English version, to the point you can have both spellings appear on-screen at the same time such as having the regular variant called "Mini Nobu" and then have the mechanized variant of one be called "Mecha Nobbu", both appearing on field at the same time.
- Underground Monkey: Originally there were only regular, silver and gold variants of Mini Nobu, all of which also had large variants, but the following events added additional variants of them. The "Mini Nobu" Command Code lampshades it by noting they're really into updating their form every year.
- Apple of Discord: Serves as this to the Saberfaces in "Fate/GUDAGUDA Order Drama CD", getting all of them fight each other over who's the best, while she can stand above them.
- As Long as There Is Evil: As Evil Nobunaga fades away, she claims that she'll return if the people "forget to be grateful to the land for its blessings."
- Big Bad: Of "Fate/GUDAGUDA Order Drama CD", seeking to become the most popular by driving all of the Saber-faces into destroying each other. She gets far surprisingly, only being found out when she gloats to herself... in front of everyone. Then Good!Nobunaga reappears, and she is promptly obliterated by the angered Saber-faces.
- Evil Twin: Parodied, as she comes out of nowhere at the end of the end of the event just because.
- No Kill Like Over Kill: After accidentally outing herself as the mastermind of the Fate/GUDAGUDA Order Drama CD, as well as the Good!Nobunaga's sudden appearance destroying any hope of survival for Evil!Nobunaga when she tried to pass off the whole thing as a joke, she gets utterly annihilated by the Sabers plus Okita's Noble Phantasms.
- Too Dumb to Live: How she gets outed and killed in "Fate/GUDAGUDA Order Drama CD," gloating to herself in front of everyone after Medusa learns her true identity.
Command Cards: QQAAB; (Q)
First Appearance: Fate/Grand Order
Illustrated by: BUNBUN
Voiced by: Ayako Kawasumi
The Final Boss of the Saber Wars event and an NPC-only Servant. An alternate version of Mysterious Heroine X born as a result of her traveling back in time, she desires to kill Mysterious Heroine X and become the most powerful Saber. She is temporarily playable in Saber Wars II, and is an unlockable Costume Dress for her counterpart.
- The Artifact: She still has Mysterious Heroine X's old animations even in reruns after her Animation Bump.
- Breaking Speech: She delivers one to Saber Lily, saying that Mysterious Heroine X only trained her because she considered Saber Lily to be no threat and only wanted to manipulate her into helping fix her ship. She tries to convince Saber Lily to kill Mysterious Heroine X while shes unconscious but it doesnt work because Saber Lily realizes that an Altria would be useless in repairing a spacecraft.
- Dual Wield: She busts out Excalibur Morgan alongside Excalibur for her Noble Phantasm, Secret Calibur.
- Hypocrite: She says its unfair that she has to fight all of the heroes at once but is perfectly willing to use dirty tactics herself like when she performed a sneak attack on Mysterious Heroine X. Nero calls her out for this.
- Me's a Crowd: After defeating her once, Ultra Heroine Z uses Saber Ninja Art: 3 Wave Duplication to create a large number of clones of herself. During the Final Boss battle, the player has to defeat nine copies of her (although the first eight of them are incredibly weak, having less than 5000 HP each).
- Palette Swap: Ultra Heroine Z looks exactly the same as Mysterious Heroine Xs first ascension except colored white and she has the same skills and Noble Phantasm. To drive it home, Saber Wars II makes her an unlockable Costume Dress for Mysterious Heroine X.
- Temporal Paradox: Her existence is this. Mysterious Heroine X went back in time to kill all of the Sabers in the past but since this makes Mysterious Heroine X a Saber (at least story-wise) in the past, another version of her must exist to defeat her. Tamamo calls it a chicken and egg situation.
Valentines: Chocolate Lady's Ruckus
- Elite Four: Four actual Servants, Nursery Rhyme, Gaius Julius Caesar, Paracelsus, and Teach, also know as the "Four Chocolate Kings".
- Generic Doomsday Villain: They're not even alive. They're just causing trouble because Nursery Rhyme's lashing out for being left alone one too many times, and Caesar, Paracelsus, and Tech are just taking advantage of the situation to steal the chocolate for their own goals.
- Golem: Made of chocolate, but same thing.
- Let No Crisis Go to Waste: As Nurse Rhyme's lashing out, Caesar, Paracelsus, and Tech all team up with other Servants and try to steal chocolate for their own plans.
Da Vinci and the 7 Counterfeit Heroic Spirits
- Antagonist Title: Their "evilness" aside, they are the the titular seven that are fought against in "Da Vinci and The 7 Counterfeit Heroic Spirits."
- Co-Dragons: The seven are this, in order to be Jeanne Alter's harem and serves her in her scheme to distribute the fake Mona Lisas.
- Everyone Can See It: Everyone, even Jeanne's own creations, can tell that she is a massive Tsundere. (Fake) Hektor even flat-out calls her "adorable!"
- I Want My Beloved to Be Happy: The reason that they where summoned was to make Jeanne Alter happy after she figured out that she wasn't born from Jeanne's hate, and is actually just a "fake."
- Poke the Poodle: There's nothing really evil about them, as they're Just Following Orders from Jeanne Alter because they want her to be happy, and the only thing that can be considered evil is them helping her with spreading the counterfeit Mona Lisa.
- My Rules Are Not Your Rules: The 7 fake Heroic Spirits that are summoned by Jeanne Alter are summoned in a different class - Alexander (normally Rider, summoned as Saber), Hektor (normally Lancer, summoned as Rider), Siegfried (normally Saber, summoned as Archer), Arjuna (normally Archer, summoned as Assassin), Arash (also normally Archer, summoned as Caster), Caster Gilles (summoned as Lancer) and Brynhild (normally Lancer, summoned as Berserker). "Fake" versions of D'Eon (Rider), Diarmund (Assassin), Phantom of the Opera (Berserker), and Leonidas (Caster) also show up, although not part of the 7 spirits Jeanne Alter summoned.
- Never Trust a Title: Although the event does involve 7 Counterfeit Heroic Spirits and Da Vinci, a much more accurate title for the event would be "Jeanne Alter and the 7 Counterfeit Heroic Spirits".
- NOT!: In a more hilarious segment, Fake Siegfried apologizes for having to fight, only not so much... The last part is even emphasized by his sprite zooming onto his face.I am very sorry that we have to fight... NOT!!
Fate/Accel Zero Order
Command Cards: QAAAB; (A)
Alignment: Chaotic Evil
Origin: Germany (Original creation)
First Appearance: Fate/stay night (as Justeaze von Einzbern)
Illustrated by: Sima Udon
Voiced by: Sayaka Ohara
The Big Bad of the Fate/Accel Zero Order event, and an NPC-only Servant. She is the ancestor of all Einzbern homunculi, Justeaze Lizrich von Einzbern, who was used as the Greater Grail's vessel. She was eventually corrupted by Angra Mainyu and manifests in the Fate/Accel Zero Order Singularity. Her class is Avenger.
- Beat the Curse Out of Her: Appears as the "Dress of Heaven" in the epilogue of Fate/Accel Zero Order significantly less hostile, and tells you that you need to destroy the pieces of the Grail left over in the form of the Elemental Iris.
- Beauty Is Bad: Her costume is a black version of Dress of Heaven/Irisviel's... except for the lack of a bra, further exposing her Navel-Deep Neckline and giving her Underboobs.
- Came Back Wrong: Background materials about Justeaze characterize her as dignified, professional and duty-oriented—even if she was pursuing the rebirth of the Einzbern's Third Magic. As she appears in her darkened state, she's somewhat unhinged, to say the least.
- Composite Character: With Irisviel. She's speaking to you in her form in the epilogue, and possibly her body as well. She also shares memories, as she comments that you should have "blown the grail up together with one floor of a luxury hotel."
- And then again when you beat the Elemental Iris and fuse them into Irisviel to increase her Noble Phantasm.
- Evil Counterpart: To the Dress of Heaven, who embodies the original uncorrupted Holy Grail. "Dark Irisviel", conversely, embodies the Holy Grail after its corruption by Angra Mainyu.
- Eviler than Thou: She immediately dispatches Matou Zouken when he finally steps out of the shadows to control the emergence of the Holy Grail.note
- I'm a Humanitarian: She consumes Zouken after talking with him and wants to devour more people to satisfy her hunger.
- Navel-Deep Neckline: Like the Dress of Heaven, she too has the same equally revealing clothing with a plunging neckline that goes down to her navel.
- Non-Indicative Name: Despite being considered Dark Irisviel in-game, she's actually Justeaze.
- Palette Swap: Literally, the only difference between her and Iri would be the coloring, her more disturbing facial sprites, and the absence of a bra, showing off her assets more explicitly.
- Red and Black and Evil All Over: Her costume is black and red just like Dark Sakura, and she is the embodiment of the corrupted Grail.
- Super Prototype: She is Justeaze, the original vessel of the Holy Grail and the ancestor of all Einzbern homunculi, who are made in her image.
- Supernatural Gold Eyes: In addition to the coloration noted above, she has the golden eyes that are very typical of an Altered Servant.
- Upgrade vs. Prototype Fight: Sort of. After you finish the main storyline of the event, the only way to procure the other copies of Irisviel/Dress of Heaven's Servant cards (to max out her Noble Phantasm) is to go around the map and defeat versions of Justeaze lingering about (ideally with your recently-acquired Irisviel to max out her bond points). Oddly enough, she manifests in other different classes.
Tenma's Marvelous Folklore: Onigashima
An oni that Kintoki and Minamoto-no-Raikou try and hunt when a singularity of the oni's kingdom appears. Is the final boss of the "Onigashima" event and in Raikou's first Interlude.
- Battle Aura: Ushi Gozen is surrounded by black-purple smoke and lightning.
- Composite Character: Raikou and "his" sister, Ushi Gozen, are the same person in this interpretation of the legend, thus the Historical Gender Flip . In addition, she subsumes the position of "monster woman" that raised Kintoki.
- Driven to Suicide: Her despair over always being treated like a monster due to her demonic nature led her to try to kill Ushi Gozen, even though, as she well knew, because Ushi Gozen is the demonic part of her being, doing so would mean her own destruction. Only Kintoki's intervention saved her life.
- Enemy Without: She's Raikou's, manifesting as the divine/oni part of her heritage that she's loathed all her life in its own body.
- Final Boss: Serves as the final boss of the Onigashima event.
- Paint It Black: Ushi Gozen's attacks have a black Palette Swap over Raikou's normal ones.
- Punny Name: Raikou has huge breasts and he's the same person as Ushi Gozen in this continuity. Ushi is often used to refer to cows, which produces milk... like a mother's breasts. So that's why she has huge breasts...
- Split-Personality Takeover: It's revealed in Onigashima that "Raikou" and "Ushi Gozen" are actually two personalities in the same body, with Raikou having sealed Ushi Gozen away within her mind and soul... and Ushi Gozen has broken free and taken Raikou over this time. According to Kintoki, this happens every-time Raikou builds up too much divine energy.
- Walking Spoiler: Talking deeply about Ushi Gozen reveals a lot about Raikou's own inner conflict.
Summer 2016: Chaldea Summer Memory/Chaldea Summer Odyssey
He serves as the main villain in the first Summer event, "Chaldea Summer Memories/Heat Odyssey," having drifted onto the deserted island before Chaldea and seeks to take it over by corrupting and trampling it. After Chaldea restores the island and prepares to leave, he attacks them only to be defeated. He survives using the Holy Grail, and seeking revenge against them, waited for 2000 years while repairing his body into that of a machine while having his children destroy the island's civilization.
- Animalistic Abomination: Most demon boars are already pretty freaky. This one's a giant mechanical demon boar, although he only became that way after repairing himself.
- Best Served Cold: He's been waiting 2,000 years since the Chaldea crew left the island to come back and take his revenge for defeating him the first time.
- Degraded Boss: While still a rare enemy, he is repurposed into a "Mecha Demonic Boar" which occasionally appears as a mid-boss enemy.
- Foreshadowing: In Altria's Brilliant Summer quest which gets unlocked before you find out about Twrch Trwyth, you face against two Giant Demonic Boars named Grugyn and Lllawin, which happen to be names for two of his children.
- Laser-Guided Karma: After his final defeat, he bemoans that he's lost everything and wonders why he has to suffer so, but Scathach reminds him that he sealed his fate after a life of stealing, rampaging, devouring, killing, and gloating over others. He admits she's right before fading away.
- Macross Missile Massacre: He can fire missiles out of his body.
- Mechanical Abomination: Becomes this after rebuilding himself a machine body, as he's still a demonic beast as well.
- Shock and Awe: Can fire lightning from his tusks.
- Took a Level in Badass: In the first part of the event, he was just a giant demon boar on par with a Phantasmal Beast. After getting the Grail and spending 2,000 years gathering power, he became a giant mechanical demon boar with the power of a Divine Beast.
- Unknown Rival: To Altria, something that he himself is well-aware of. He despises the fact that Altria saw him not as a fellow king, but as a mere beast and pest to vanquish back in the day.
- Voluntary Shapeshifter: Takes Altria's appearance when first revealed, until the trickery is revealed by Scathach.
- We Can Rebuild Him: He does this to himself with the Grail's power after being defeated 2000 years ago by the Chaldea crew from his perspective.
A Magical Girl's Travelouge ~Prisma Corps~
The magical girl's familiar that follows the Magical Girl of Honey and Geis, Connacht☆Medb, whether or not he likes it. While introduces as being just a modified version of Cú Chulainn Alter, he survived the Singularity and now lives in Chaldea as a plush toy.
- Aloof Ally: While Cú Chulainn Alter is mainly passive-aggressive with Medb, Mini Cú has little courtesy with her, arguing with her regularly.
- Ambiguously Brown: His portrait has the same dark-skin that Cú Chulainn Alter is shown in his artwork. Unlike Cú Chulainn Alter, this persists onto his sprite, artwork in Craft Essences and even the official plush.
- Boss in Mook's Clothing: The raid battles against him and Connacht☆Medb treats Medb as the main target, but he ends up being the bigger threat as Medb starts the battles with buffing Mini Cú. He also has the same skillset as regular Cú Chulainn Alter.
- Living Toy: Somehow he survived the Singularity and ended up in Chaldea as a "plush toy", with the actual Cú Chulainn Alter trying to get rid of it by giving it to you as a return gift during his Valentine scene. It later develops a rivalry with the Viy replica Anastasia gives to you.
- Mentor Mascot: Is a parody of the various magical girl mascots that help the magical girls as while he tries to get Medb not to do anything stupid, the two of them end up arguing a lot.
- Ascended Meme: Fake Ibaraki-Douji's nicknamed "Banana Oni" in the english translation of the game.
- Bonus Boss: They never attack directly, only appearing in the Extra chapters of each episode.
- Cloning Blues: Averted. They're all aware of the fact that they're fakes, but it doesn't seems to bother them at all.
- Dark Is Evil: The dark Kaleidosticks that creates the Fakes are completely shadowed-in versions of Magical Ruby while blushing. Minus the stars and blush itself, it makes them look devilish to contrast Ruby's angelic appearance.

First Appearance: Fate/Grand Order

- Arc Villain: Of the first part of the Prisma Illya event, though her influence is felt even into the second part.
- The Assimilator: Admits that she intends to do this to Miyu once she breaks her will and do the same to Illya. She's already gotten to work on Chloe.
- Demonic Possession: She seemingly lacks a body of her own anymore, so she takes control of Chloe and uses her to fight the party for a World End Battle.
- Dimension Lord: Of the Reality Marble. She later passes it on to the event version of Helena.
- Despair Event Horizon: She hit this in her backstory and kept right on going.
- Living Shadow: When she's not possessing Chloe, she appears as a shadowed-out version of Illya from the Prisma Cosmos CE.
- Magical Girl: She's apparently the first to hold such a title.
- Mark of the Beast: When she possesses Chloe, she becomes surrounded in a purple Battle Aura and her eyes glow purple.
- My Greatest Failure: Sees her choice to kill her friend Mila to save the world as this, lamenting that she couldn't save her too.
- Orcus on His Throne: Despite being the source of the Reality Marble and the one who kidnapped Miyu in the first place, she spends most of her time behind her barrier trying to break Miyu's will while Medb takes the main antagonistic role in trying to capture the heroes and their jewels obtained from the other magical girls. Of course, it also works in her favor since she needs Illya and the jewels for her plan to succeed, and since Illya can only reach her once she has all the jewels anyways she's better off just waiting.
- Pseudo-Romantic Friendship: Heavily implied she had one with Mila, who she ended up fighting and killing to save her world. That was the beginning of her own fall, as well.
- Reality Warper: The entirety of the Prisma crossover event takes place in her Reality Marble.
- Together in Death: Implied with her and Mila.

- And Your Reward Is Clothes: Her appearance can be purchased for Illya during the rerun. This does not change Illya's personality.
- Arc Villain: Of the second part of the Prisma Illya event.
- Dark Is Evil: She wears an all-black dress, and during battle, a darker version of Illya's third ascension outfit. She's also shown to be a lewd and very much evil threat.
- Face of an Angel, Mind of a Demon: She looks just Illya, but is cruel, sadistic, and lewd.
- HP To One: Her "Fall to Heaven" skill reduces a single target's health by 5000 HP. If they have less than 5000 health, the skill will reduce them down to one HP.
- Laughably Evil: She's noticeably less serious than the First Lady, having far more comedic moments than the former (including following her defeat). This is more than likely due to the influence of the "Magical Gentlemen".
- Palette Swap: In the final World End Battle, she takes form as the Illya from the Prisma Cosmos CE with a black and purple color scheme and her model in-battle has Illya's final ascension in the same colors.
- Reality Warper: She hijacked control of the Reality Marble from Helena and warped it, and mentions once she vanishes it will return to normal.
- Tulpa: Given life by the remains of the First Lady's power and the Magical Gentlemen's visions of a "pure and ideal" Magical Girl. Unfortunately since the Magical Gentlemen have very... suspect opinions of girls, Testament ended up as anything but pure and ideal by any sane man's standards.
- Yuri Fangirl: Claims that magical girls should only be allowed to love other magical girls.
All the Statesmen! ~Learn With Manga Records of the American Frontier~
Illlustrated by: Riyo
Voiced by: Tomoko Kaneda (FGO Fes 2018 Kigurumi Show)
A Master from a Parallel Chaldea. She is capricious and treats her Servants as tools to appease her greed and possibly lust. She appears in the Learning with Manga! FGO "All The Statesmen" event. She later returns as the mastermind behind the Learn with Manga! F/GO Vol 2 Release Commemoration Campaign by use of her manga book, which causes anyone who reads it to awaken their gay urges, in an effort to bring peace to the world.
- Adaptational Jerkass: Amazingly enough, the Event found a way to make this Memetic Psychopath even more evil. While Gudako is a needlessly-cruel sex-crazed chaotic being, she clearly cares for Berserker (who she effectively mothered). This iteration abandons Bunyan without a second thought when she turns out to be a 1-Star.
- Ascended Meme: Personified. She's a horrifically abusive and dangerous Master, a nod to how the Learning with Manga! FGO audience and creators treat her as the most dangerous threat to humanity instead of anything like the Beasts, Foreign God, or any other threats known to mankind.
- Attention Whore: One of her defining traits during live events. The mascot has the tendency to leave the stage to approach the audience or will do something else to get their attention. Staff members even have to carry her out of the stage.
- Bad Boss: Not only does she treat lower-rarity Servants as worthless, even her SSR Servants are badly trained and not raised with proper care.
- Breaking the Fourth Wall: During your first meeting, she refers to this kind of talk as something only other Masters would understand, and the protagonist, perhaps due to Reality Bleed, seems to do so. She frequently refers to game mechanics and rages against how she hasn't gotten as many 5* Servants as she would like.
- Clothing Damage: For some reason, her clothes are all torn up throughout the event, though the chibi art means there isn't much shown.
- Did I Just Say That Out Loud?: Has this just before being sent back to her world, realizing that she just stated she wanted to do lewd things to her Servants while in Bunyan's Reality Marble. Edison just wants her gone by then.
- The Dog Bites Back: Her Servants Jack and Nursery Rhyme abandon her after her loss because of her cruelty.
- Eldritch Abomination: After her defeat, she appears like this◊. Edison and Geronimo actually question if she was really human, or rather if she still is one.
- Evil Cannot Comprehend Good: She doesn't understand why the protagonist or anyone else would care about weak Servants.
- Even Evil Has Loved Ones: It's revealed during "All the Statesmen" that she deeply misses her version of Dr. Roman. However, Mash tries really hard not to think about the implications of the fact that her version of Mash isn't with her.
- Evil Twin: To the protagonist. Even if you're playing as a male, they comment on the resemblance.
- Heel: She takes this role in real-life kigurumi appearances. She entertains the audience by being a troublemaker and Attention Whore, and she's outright hostile towards other mascots as well as staff members.
- Hero of Another Story: She outright states that she's fought for and saved Humanity in her world too.
- Hoist by Their Own Petard: Disgusted when Bunyan, whom she hoped would adopt traits of a creator god thanks to their association with the creation of many North American landmarks, was only a simple phantom spirit and a 1* Servant, she abandoned her in the woods to die. This act led to the other Master meeting and befriending Bunyan, and thus discovering and stopping her scheme.
- I Have No Son!: She created Bunyan but promptly abandoned her when she turned out to be a 1* Servant. She's perplexed that the protagonist would show any trust to or care for someone as weak as Bunyan.
- Kick Chick: Due to the designs of the mascot kigurumis, she has difficulty punching someone with her short arms, so she only relies on kicks. There are many convention pictures of her stepping on people.
- Lies to Children: Implies her Breaking the Fourth Wall terminology is merely something you would understand and that she's doing something... else.
- Nightmare Face: Pulls a truly glorious one in the event's finale, realizing that she just stated she wanted to do lewd things to her Servants within Bunyan's Reality Marble.
- No Name Given: She introduces herself but it is The Unpronounceable with Berserker-ese text.
- Pet the Dog: Her second appearance has her taking a more selfless route, attempting to play matchmaker to create a more peaceful world. (Of course, she's also just horny.) She also genuinely accepts the error of her ways when shown she was wrong.
- Reality Bleed: During her event, a lot of characterization and jokes from the Learning with Manga! FGO slip into the regular Chaldea. The protagonist and Mash are also affected, the former in particular becoming Denser and Wackier, adopting a lot of the Nameless Master's Breaking the Fourth Wall jokes and becoming greedier and more-lustful about the situations they fall into. Mash, still her usual self, suddenly adopts a Meta Girl perspective and keeps up with the protagonist's fourth wall-breaking shenanigans with (slightly more serious) commentary about the game.
- Series Mascot: This version of the female protagonist is commonly used as Grand Order's mascot primarily for her breakout troublemaker personality from the gag manga, and even has made appearances live in a mascot costume to act out skits at conventions, particularly as the Heel. Like the protagonist, she's referred to as "senpai" by Mash and MCs.
- Super-Deformed: As per Riyo's style.
- This Loser Is You: Much like Gudako from Learning with Manga! FGO, she is meant to represent the average FGO player: self-indulgent, questionable with their money, and needing no empathy for pixels on a screen. Unlike the webcomic, the event underscores what such a Master would become within the canonical setting of FGO if they didn't smarten up — a serial rapist living a power fantasy that doesn't care one whit for their Servants or the world around them beyond what they can do for them.
- Unwitting Instigator of Doom: Using a Holy Grail to power Bunyan up really did not go as planned, as it allowed Bunyan to create an alternate dimension from her mind populated by living beings (a step up from even normal Reality Marbles) and runs the ultimate risk of creating a Reality Bleed across the multiverse that will inevitably self-destruct if not stopped. And all because she really wanted a 5* Servant... should've just waited for the GSSR.
- Watsonian versus Doylist: How acceptable is Riyo Gudako's behavior? Depends on how you look at it in-story or out. Someone playing a mobile game, selling off one stars, obsessing over waifus and complaining about stats and throwing game pieces away? Not a problem, it's partially the point of the game after all. In-story, doing this to Servants who are actual people? You Monster!!
- Villain Forgot to Level Grind: Despite having some good welfare Servants and even a trio of 5 Star Saberfaces, Gudako's obsession with waifus over actually leveling them up, like an actual player would, means they're relatively easy prey for all but the most entry-level of Masters.
- Villain Has a Point: Fate Grand Order is a grindy, money-grubbing gacha game with stingy drop rates in terms of both upgrade items and high-powered characters, is deliberately designed to create a social system of haves and have-nots between the paying and free players, where the former are more likely to be picked for supports, and won't even implement an NP Skip button. That said, she also has a shallow and limited understanding of the game, dismissing every Servant of 3* rarity or lower as worthless when most of them (including Bunyan!) can prove very powerful or occupy useful niches after being properly upgraded and leveled, and says she wants the game to have more "beautiful female saberfaces," so she doesn't have too much of a point.
- Well-Intentioned Extremist: Her return has her use her manga to create a more peaceful world. Too bad she's still Gudako, with da Vinci herself calling her out for not accepting the most important parts of romance, development and chemistry.
- Yuri Fan: So much so that exposure to her manga has been known to awaken gay urges. Da Vinci calls her out on this by saying that she needs to accept that the most important part of any romance is their development and chemistry, and she's just mashing together pairings regardless of whether they make sense (such as Kiyohime/Elisabeth, when Kiyohime has Single-Target Sexuality).
- Anthropomorphic Personification: Of the United States of America and the country's desire for freedom. She's compared to Uncle Sam in this regard.
- Anti-Villain: For all her determination in killing Bunyan, she admits that she never wished to make her suffer. She even admits after her defeat that she only watched Bunyan from afar, and never did anything else, when all Bunyan wanted was a friend.
- Grand Theft Me: She takes control of Altera for the sake of ending Bunyan.
- Knight of Cerebus: She reveals the true reason for why the "All The Statesmen!" Singularity exists, and is played dead serious.
- Running Gagged: Altera appears in nearly every section of "All The Statesmen" claiming to be various American figures as a Running Gag. Columbia seems to be the same... except A) it's the actual Columbia in Altera's body, and B) her appearance is played entirely seriously to the point of her segment being a Wham Episode for the event. The next time Altera appears, it's as her original White Titan self.
- Well-Intentioned Extremist: She wants to kill Bunyan because the Singularity created by her will bleed into the real world and destroy itself. This puts her at odds with the Protagonist, who wants to save her instead.
Summer 2017 - Dead Heat Summer Race! Death Jail Summer Escape!
- Animalistic Abomination: It is a colossal, golden bull skeleton with bird wings. When seen in profile, its skull resembles a bull's, with eyes and teeth more evocative of a crocodile. Viewing the beast head-on reveals the face of a Sumerian king, formed by a second pair of eyes and a "beard" formed of scales.
- Animated Armor: Because the real Gugalanna is still a tiny animal, it is animated by Ishtar and the thunderclouds it generates.
- Brutish Bulls: A massive divine bull whose destructive power makes it an existence powerful enough to fight Tiamat for a time.
- The Cameo: Reappears in "CEO Crisis 202" as the fifth and final raid boss under the name "God's Finger Tapping 'Buy Now'".
- Dismantled MacGuffin: The golden pieces that were incorporated into each racer's race car, (or smashed for Nobu/X's rocket), made up Gugalanna.
- Eyes Do Not Belong There: It has pair of human-like eyes on its forehead, making it look like it has a human face on its bull head.
- Giant Foot of Stomping: The battle against it consists you chipping away at one of its leg, which is still bigger than any of the Servants and all of its attacks are variety of stomps.
- Gold and White Are Divine: The majority of its body is golden, but there is a smattering of white here and there, especially on its face.
- Rule of Three: A third version of Gugalanna called Gugalanna Mark III appears during Ishtar's second Interlude.
- Shock and Awe: Its creation spawns a massive lightning storm, and it discharges lightning for attacks. In fact due to Gugalanna being just an ornate skeleton of a bull, when it moves it forms storm clouds around it in the visage of an actual bull.
- The Plan: Gugalanna Mark II is the result of Rider Ishtar's plan to recreate Gugalanna after being mocked for losing it in Babylon. Of course, the event would never have happened if her "Fate/Strange Fake" counterpart hadn't stolen it from her.
- Walking Spoiler: Gugalanna Mark II's existence reveals the truth behind Ishtar's plan for the entirety of the second Summer event.
Christmas 2017 - Merry Christmas from the Underworld
- Bullying a Dragon: Mocked Ereshkigal in the backstory, and got beaten up by her after he took her up on her challenge and went down to the Underworld. Too bad it backfired on Ereshkigal when she didn't get what she wanted.
- Conflict Killer: "Merry Christmas from the Underworld" for the most part is a tale of Ereshkigal's self-loathing and breaking her oath of not directly interfering with humanity, believing she has to atone by fading away and relinquishing control of the Underworld to a more responsible god, and the Protagonist fighting tooth and nail to convince her otherwise. However once Nergal's real intentions are made clear - that his lingering malice just wants Ereshkigal out of the way so he can turn Kur into a complete and utter hellhole - getting through to Ereshkigal becomes much easier, and the conflict becomes a much simpler case of "punch out the bad guy".
- Dark Is Evil: The straight example to his former master's subversion. He plans to remake the gloomy-but-peaceful Underworld Ereshkigal has built into a hellish nightmare of plague and suffering that exists only to glorify himself.
- Everybody Hates Hades: Discussed, actually. Being Nergal's malice given form, the Nergal of the Underworld lacks the complexity of his original self, and is obsessed with the idea that the Underworld should be a place of humiliation and suffering for everyone the way it was for him. That's why Dumuzid jokes he never did have many friends as he dies.
- Evil Cannot Comprehend Good: Quite literally, as Nergal's malice only contains the feelings of anger and humiliation Nergal felt from his battle and loss against Ereshkigal, not the respect Nergal gained for her after losing fair and square. As a result, the malice can't comprehend or accept that his origin willingly handed over his Authority to a "lesser" goddess.
- Exact Words: Oh, he gave Ereshkigal half of his divine Authorities as per demand, but he made sure to give her the Plaguemaster powers that she had no interest in.
- Final Boss: He (or rather, his malice) serves as this to not only the event, but the entire Arc 1.5 as a whole.
- Graceful Loser: The real Nergal admitted defeat and submitted his Authority as a gesture of respect, since his arrogance was tinged with generosity. His malice, meanwhile, rants about how the Underworld should be a place of torture and humiliation, while also wanting to be apart of humanity's mythology.
- The Heartless: Being formed from rage and regret, Nergal's malice cannot feel or understand the positive emotions of others, not even his own past self's.
- It's All About Me: As Nergal's malice dissipates, it reveals the real reason that it wanted to take over the Underworld from Ereshkigal was so that he could be remembered as apart of humanity's myths.
- Know When to Fold 'Em: According to Gilgamesh and Dumuzid, Nergal was one of the few Sumerian gods who could swallow his pride and admit his fault. It was why he ultimately acquiesced to Ereshkigal after his defeat (not that it stopped him from taking a bit of minor revenge by denying her what she truly wanted from him).
- Large Ham: In the "reenactment" of the conflict between Nergal and Ereshkigal, he's portrayed by Ozymandias, another arrogant being associated with the Sun. And judging by how much Ozymandias was hamming it up, Nergal was likely quite the ham too.
- Plaguemaster: Being the god of the sun, Nergal was also the god of the summer fevers and plagues that struck down the Sumerians each year. He left this power to Ereshkigal upon death, and it forms the core of the villainous Nergal in the story.
- The Power of the Sun: The God of it, in fact, for the Sumerian pantheon. This was of particular interest to Ereshkigal, who wanted his Authority over the sun in order to use it for her kingdom. He was God of the sun, but not just its light, but also sunspots as well, hence his association with summer fevers and plagues.
Cosmos In The Lostbelt Event Villains
Valentine 2018 - Prosperous Chocolate Gardens of Valentine
- Ambiguously Evil: It's played with through the event. While pretending to be Semiramis, Chaldea starts to wonder why she's so enthusiastic about making chocolates when she refuses to slow down production, despite having made such facilities as a building that can slow down time all to improve chocolate production. It's then revealed that she was evil, but only because the Semiramis Chaldea was interacting with was a fake. Even then, it's not clear if her flooding of Chaldea was because she no longer needs them, or if she just doesn't see anything wrong with that. Her speech as it happens doesn't really clear anything up either.Chocoramis: Yes...more. More! Show me...the sweet world of chocolate! Chocolates making more chocolates! Chocolates taking over everything! A chocolate world made by chocolates for chocolates!!!
- Beware the Silly Ones: Despite being objectively ridiculous, this silly event villain came closer to outright destroying Chaldea than anyone else before the Lostbelts, by flooding it with endless supplies of chocolate.
- Blue-and-Orange Morality: Doesn't see anything wrong with flooding Chaldea, even stating to the protagonist that "a human like you need not understand my words."
- Can't Kill You, Still Need You: As much she would like to kill the original, she still needs her Noble Phantasm and Holy Grail to create her empire of chocolate. Hence why she sealed her away in the chocolate fountain.
- Chekhov's Gun: The chocolate fountain. It turns out it was a prison for the real Semiramis, sealed away by her, and powered by the Holy Grail she was using to power her Kingdom of Chocolate. This is Foreshadowed by an early Dove Report noting that the fountain hides a secret.
- Cloning Blues: Chocoramis wanted to rule of a kingdom of chocolate, due to her being sentient chocolate and an empress without a kingdom, due to copying the original's personality. Semiramis bluntly tell her that she just a failure and her shame, not even worthy of being eaten.
- Corrupt Corporate Executive: At first, she just seems to be trying to be starting a chocolate factory, but as more of the factory expands, starting with the Chocomandrakes, the more it's clear she has ulterior motives.
- Didn't Think This Through: Her plan falls apart because she didn't take into account the fact that even Holy Grails can run out of power. Once it does, not only is her dream of an empire of chocolate ruined and made an enemy of Chaldea, but also unseals the real Semiramis.
- Evil Doppelgänger: A chocolate model of Semiramis, who took on her personality and sought to create a kingdom for chocolate.
- Fiction Business Savvy: Is smart enough to take advantage of Edison's and Tesla's rivalry with AC/DC currents to double her chocolate productions. When Charles Babbage asks to joins the competition to prove the superiority of steam, she lets him join to triple it.
- Five-Second Foreshadowing: As her chocolate floods Chaldea and her rant confuses the protagonist, she states that "a human like you need not understand my words." While it could be translated that its because of Semiramis's demi-goddess nature, in actuality, it's because she made of chocolate.
- Foil: To the Choco Servants of the previous Valentine event. The Choco Servants and Chocoramis herself may seem similar due to being golems made of chocolates resembling Heroic Spirts, but while the Choco Servants were just soldiers serving under "Four Chocolate Kings," to steal all of Chaldea's chocolate for their various reasons, Chocoramis is completely sentient and betrayed her creator. She also only sought to build her kingdom with the help of Chaldea, but whether her overloading the facility with chocolate was intentional or she didn't see anything wrong with it, it was surely to fill the Earth with chocolate.
- Hoist by His Own Petard: In the end, she brings about her own downfall due to her over-using her Holy Grail, screwing herself over when the real Semiramis frees herself and ending her plans of a Kingdom of Chocolate.
- Nice Job Fixing It, Villain: Shoots herself in the foot due to literally overloading Chaldea with too much chocolate, which in turn not only turns Chaldea into her enemy, but exhausts her Holy Grail and frees the original, who all proceed to gang up and destroy her.
- No Name Given: Doesn't really have a name, and is given one on the spot by the protagonist once she's revealed to be a fake made of chocolate.
- "Not So Different" Remark: Obsession with chocolate aside, it's pointed out by both Semiramis herself and the protagonist that Chocoramis is effectively a carbon copy of Semiramis down to her own values.
- Start My Own: She was an empress without a kingdom due to being chocolate so she decided to make a kingdom of chocolate to rule over.
- Walking Spoiler: Chocoramis's existence reveals the true reason behind the 2nd Valentine event.
- You Have Out Lived Your Usefulness: Ambiguous. It's unclear whether the flooding of chocolates in Chaldea was because she's finally reached peak production and no longer needs Chaldea's services, or giving them exactly what they want and doesn't see a problem with literally drowning them in the goods, so long as it helps her create her Kingdom of Chocolate.
Apocrypha - Inheritance of Glory
Illustrated by: Konoe Ototsugu
Voiced by: Nobuyuki Hiyama
Darnic is the main villain of the "Inheritance of Glory" event. Because of his Fusion Dance with Vlad III in Apocrypha, upon death his soul was brought into the Grail alongside Vlad's but unable to be converted into energy because he was not a Servant. Several years after the events of Apocrypha the remnant of Darnic begins trying to usurp control of the Greater Grail from its new administrator, Sieg.
- Determinator: He continues to exist despite his sense of self slowly fading away in order to finally obtain the Grail. He rants that he refuses to give it up to anyone, as he will not allow the sacrifices he made be All for Nothing, and even laughs when Semiramis and Sieg call out horrified that he's forcibly creating a mimicry of the Greater Grail while inside the Greater Grail (heavily implying this would destabilize the entire thing and cause the magical backlash to disrupt the Layered World of the planet) that it's the duty of a magus to go Beyond the Impossible. Even after being beaten down by Sieg and all the other Servants of the Black and Red Factions aside from Vlad III, he still tries to keep going until Vlad III finally appears and impales him, and it still requires a moment of Talking the Monster to Death to finally make him give up.
- Early-Bird Cameo: His first appearance in Grand Order was on the Golden Millenium Tree Craft Essence.
- Eats Babies: As if all the other things Darnic has done weren't horrible enough, Sieg reveals that Darnic had specifically consumed the souls of infants in order to prolong his life. Overlaps with Immortality Immorality.
- Face Death with Dignity: He accepts his demise by Vlad's spear after he tells him that his dreams were admirable but ultimately something to let go of, with him deciding to let go of his dream and finally rest.
- Flunky Boss: The final boss of "Inheritance of Glory" is not against Darnic himself, but rather his mimicry of the Greater Grail he creates using his 87% control of the Greater Grail's system that can summon countless copies of the simulated Servants to aid it and can switch its own Class on the fly to keep the enemy on their toes (represented in-game by being able to appear as a Raid Boss with any one of the seven standard Servant classes, while the proper final battle is with it as a Ruler).
- "Groundhog Day" Loop: Part of Darnic's plot involves creating mindless but full-powered copies of the Servants that fought in the Great Holy Grail War and having them fight in conflicts where they simply come back after dying. According to Sieg there have already been over 10,000 repetitions by the time the event starts. His ultimate endgame was to have their true selves eventually be summoned forth in order to have a proper final Great Holy Grail War which would allow him to claim full ownership of the Grail at long last.
- Hoist by His Own Petard: He specifically went out his way to ensure Vlad III couldn't be properly summoned and only remain as a mindless puppet for his schemes, as Vlad III was the only one who could truly defeat him, but the very tens of thousands of simulations he put into motion as well as the other Servants overpowering him finally weakened his own control enough to let Vlad III be summoned without his knowledge.
- I Can Still Fight!: Outright proclaims this as the Servants overpower him, until Vlad III dissuades him with a Kazikli Bey.
- Jerkass Has a Point: When Sieg calls him out on his selfish desire for the Grail, Darnic fires back that he's the one who took it away from the world and is now just sitting around waiting for someone who will likely never come back to him. Sure, Jeanne is trying and does succeed eventually, but neither Darnic nor even Sieg at that moment have any reason to believe it possible, and it does get Sieg to go silent.
- Karmic Death: Is killed by Vlad, his own Servant who he forced to become a vampire and fuse with him, although Vlad himself doesn't see it as "karma".
- Load-Bearing Boss: If what's left of Darnic were to disappear then the recreation of the Great Holy Grail War inside the Greater Grail will vanish, and so all of the Servants in it would disappear too.
- Loophole Abuse: The entire reason for his current existence. Because of his Fusion Dance with Vlad III, he ended up being drawn into the Greater Grail with his death at the hands of Amakusa...but because he was still human, and not a Servant, the Grail didn't break him down into energy, eventually allowing what was left of his spirit to try and take over the Greater Grail much like how the Holy Grail identified Angra Mainyu as a "human" rather than a Servant and attempted to grant his wish, becoming corrupted in the process.
- Mercy Kill: Mordred points out as Darnic is now, they're basically putting down a rabid dog rather than a real villain, and even Vlad III views his killing of Darnic as both his duty as a hero and a mercy to his former Master.
- Merger of Souls: It's pointed out that this "Darnic" is effectively a hybrid of the souls of the original Darnic, the innocent souls he devoured to prolong his life, and Vlad III that's barely clinging to the sense of self of Darnic. Indeed, Semiramis addresses him as "Vlad III"...or rather, a twisted mockery of him.
- Motive Rant: Angrily rants that he deserved the Grail more than anyone after everything he threw away to obtain it. Not the founding families who grew fat in indolence, not Amakusa who stole it out from under his nose and killed him, and especially not Sieg who happened to be the last one standing to get it and is waiting all alone for someone who Darnic claims will never come back to him.
- "Not So Different" Remark: From Vlad III, as pointed out by Vlad III himself. Both of them have dedicated themselves to impossible dreams even they know deep down they'll never achieve, but do so regardless because they are unfailingly loyal to those impossible ideals.
- Older Than He Looks: He was already over a century old during the events of Apocrypha which was set in 2004, and that's not even accounting for the unknown amount of time between then and his appearance here.
- Our Ghosts Are Different: He's not exactly the real Darnic at this point, but rather the remnants of his wish to obtain the Grail, as well as carrying the remnants of Vlad III within himself. Mordred notes they're effectively putting down a rabid dog rather defeating a true villain.
- Peaceful in Death: As he dies, he flashes a genuinely peaceful smile.
- We Can Rule Together: Pulls this on all the Red and Black Faction Servants, telling them if they so wish, he will allow them to reincarnate into the world properly and live their new lives however they desire, since they will survive as long as he himself remains in control of the Greater Grail. All he desires in return is for them to let him have the Greater Grail and leave him in peace. They tell him to his face to sod off, as it would either trod on their pride as heroes or it would mean helping someone they personally loath. He then admits he suspected as much, but he had to try the easier sell first.
- Your Soul Is Mine!: Sieg notes that Darnic did this in life in order to prolong his life and power, much like how Servants can do so, and he definitely consumed more than one unfortunate soul.
Murder at the Kogetsukan
- Alas, Poor Villain: She kills herself than let herself be punished by the crime families, and tells Eva, Juliet, and Cain to be better than she was as the poison kicks in.
- Better to Die than Be Killed: After she is revealed to be the killer, she commits suicide rather than be punished by the crime families, stating she deserves this for what she's done.
- "Could Have Avoided This!" Plot: Harriet admits that had she just told her father from the start twenty years ago that Aaron was the father of Juliet and Eva rather than lie or even if she just came clean to the people here in the present, instead of fearing the mere potential of a war, it's likely none of what occurred during the event would have happened.
- Foreshadowing: There is plenty of hints that Eva is actually Juliet's sister rather than Harriet and that Eva and Juliet are Aaron's children.
- Dr. Hawthorne states it's interesting when twins have different personalities after Juliet, Eva and Harriet discuss if Juliet is going to take a bath. It wouldn't make sense if Hawthorne was talking about Harriet and Juliet as Harriet only suggested Juliet take a bath. In comparison Juliet and Eva had a disagreement with Juliet saying she doesn't need a bath because she isn't dirty while Eva saying Juliet shouldn't stop taking care of her appearance.
- When the protagonist and Hawthorne overhear a conversation between Morris and Juliet where the former expresses that he's more interested in her younger sister due to her attitude and looks. This would be rather odd if applied to Harriet (who looks nigh-identical to Juliet and mocked Morris some time earlier) but makes much more sense when applied to Eva (who noticeably has a much more mature appearance and was flirting with Morris in that same earlier cutscene).
- When the planned engagement is changed to Chris and Juliet after Morris goes missing, it's Harriet who confronts the protagonist and tells them about how they're Juliet's Only Friend due to her connections as a Mafia Princess and seems oddly insistent on pressing them about how they feel towards Juliet. The mature way she talks doesn't at all seem like how a younger sister would act, but would fit rather well for a mother concerned for her daughter.
- Juliet states she and her sister are fraternal twins and she doesn't really see the resemblance. This wouldn't make sense if Harriet is her sister as they look identical but fits with Eva since she looks nothing like Juliet.
- When the protagonist asks Eva a question about if she saw anything unusual the night of Chris' death and caps it off with "Ms. Violet", Eva expresses that's a "strange question" and states "Mother" turned in early last night.
- Adamska states his wife was against Juliet and Morris' arranged marriage which hints at Harriet's goal.
- Aaron asks if he's met Juliet before as he's bedded so many women in his past, he forgotten a lot of them, this hints at his and Harriet's one night stand that resulted in Juliet and Eva's birth.
- Happily Married: Adamska and Harriet. It is even revealed that Adamska happily married her despite knowing she was pregnant from a tryst before they met.
- Hero Killer: She kills lead detective Sheringham, who looked like Holmes. Holmes himself isn't happy when he hears about this. Averted, as it turns out that Sheringham was Holmes all along, having faked his death to catch the her off-guard.
- Platonic Life-Partners: Dr. Hawthorne and Juliet's mother Harriet are old friends who have spent a long time together due to Hawthorne being the Violet's family personal doctor. The doctor admits he had a crush on Harriet in his youth but was simply too scared of her family to act on it and is grateful to the family for his stable profession.
- Shotgun Wedding: Zigzagged as Harriet was forced by her father to get married after she gets pregnant but she isn't forced to marry Aaron because she lied and didn't tell him he's the father because she didn't want to risk the Feuding Families erupting into full-out war. She instead marries Adamska who fell in love with her the moment they meet for a matchmaking. She admits that had she come clean, she might well have married Aaron and prevented all of this.
- Surprise Incest: The reason Harriet committed the murders. She does not want anyone to know that the marriage would in fact be between half-siblings if it went through and spark a war. Indeed, she's so scared of even the knowledge that they're step-siblings at all would be enough to spark one, which is why she refuses to answer honestly when Morris and Chris ask why she's so insistent on stopping the engagement.
- Walking Spoiler: Just trying to talk about her reveals the event's biggest twists and identity of the killer.
- Well-Intentioned Extremist: Why Harriet kills Chris and Morris. She didn't want anyone to find out that the marriage would in fact be between half-siblings if it went through, unable to get over the fear that even without the engagement just the knowledge of them being half-siblings, and thus her illicit liaison with Aaron from decades ago, would spark a war.
GUDAGUDA Strange Tales of the Imperial Holy Grail ~ Far East Devil Battlefront 1945
- Alternate Self: She is much more of a threat to the protagonist than the playable version.
- Big Bad Wannabe: She looks to be the main villain of the 3rd GUDAGUDA event at first and is considered one of the most threatening foes against the protagonist, but the reality is she was always just a pawn in Mitsuhide's schemes, and her arrival was the last part of his long-running scheme to create his "perfect" Nobunaga with the Holy Grail. She's simiarly upstaged in "GUDAGUDA Final Honnoji" by the threat of Demon King Nobunaga and High Priest of Makuzu.
- Darker and Edgier: This version is something closer to an Alter version of Nobunaga as her more serious side is greatly emphasized over her gag qualities. This is much more significant than it appears at first.
- Foil: To "Evil Nobunaga" of the first "GUDAGUDA" Event. Evil Nobu was fought at the end of the event as a parody of the Evil Twin trope. Kaiser meanwhile is fought at the beginning of the event, and is played completely seriously.
- Knight of Cerebus: Her presence clearly sets the tone for the first half of the 3rd GUDAGUDA event. And in the 4th GUDAGUDA event, she's both the first Nobunaga to actually die and gives the first hints there's more to this Singularity than just a There Can Be Only One scenario in play.
- Literal Split Personality: She's technically only part of Oda Nobunaga, as when Nobunaga was originally summoned to the Grail War, she managed to remove part of her Spirit Origin (the part familiar to the protagonist and the "gag character" they know so well) and put it inside her brother Nobukatsu, leaving behind her more serious self.
- Not So Stoic: Though she is a dangerous threat to the protagonist, she still makes the same "Koha-Ace" face as the original.
- Putting on the Reich: Her fashion sense is modernized and sharp, near-akin to Imperial Japanese Army uniforms. She's also distinguished by having advanced weaponry evocative of Stupid Jetpack Hitler.
Serva★Fes 2018 - Servant Summer Festival!
- Cosmic Horror Reveal: Nothing quite like finding out a literal Lovecraftian horror is behind the Lighter and Softer Summer event.
- Eldritch Abomination: Nyarlathotep is one of the Outer Gods of the Cthulhu Mythos, acting through BB in an attempt to "save" humanity.
- Greater-Scope Villain: Of "Servant Summer Festival," being the one who gave BB the power to create the Ground Hog Day Loop. Though in the grand scheme of things, he's more of a middleman compared to the Foreign God.
- Ground Hog Day Loop: His Authority is the ability to rewind time, which he gives to BB in order to trap the Protagonist in a time loop.
- No Name Given: Is never referred to anything more than an "evil god" by the characters. The fact that he is even identifiable as Nyarlathotep is Mash calling BB "BBHotep" after the revelation and the three-lobed eye. Additional BB identifies herself as one of the Pharoahs in her My Room if you have them. "The Black Pharoah" is one of his many masks.
- Sadist: The most human of the Outer Gods also makes him the most sadistic to humanity's suffering, and what allowed him and BB to become close friends.
- Walking Spoiler: His existence not only reveals that BB is the true Foreigner of the event, but that it does so to keep humanity safe from the Foreign God.
- Well-Intentioned Extremist: He's pushing the envelope, but his twisted love for humanity caused him to give BB his powers to let her go and "save" humanity by trapping them in a Ground Hog Day Loop paradise.
Halloween 2018 - Mysterious Country of ONILAND ~Demon Ruler and the Golden Kamuy~
The Great Oni Vermillion Dragon, who serves as the main antagonist of "The Land of Mystique, Oniland! The Great Oni and the Kamuy's Gold" as the owner of the titular park in control of the Kamuy's Gold that combined with a Holy Grail to create the Singularity.
- Antagonist Title: They are the titular Great Oni in the event title.
- An Axe to Grind: They swing around a giant stone ax nearly as big as themselves.
- Big Red Devil: Takes the form of a massive shadowy brimstone Oni. It's actually a shell formed by the Kamuy's Gold in Elisabeth's possession.
- Big "SHUT UP!": Prone to launching variations of this when pissed off, and they only get more frequent and louder as they approach their Motive Rant and Villainous Breakdown.
- Card-Carrying Villain: At the end of each episode, the Great Oni holds an cartoonishy evil monologue about what they are going to do in the next episode.
- Degraded Boss: Heian-kyo introduces two enemies called Hakushikijyo and Torakuma-douji who are recoloured version of Vermillion Dragon.
- Even Evil Has Standards: The Great Oni plans to break up couples with the tea cup rides but is decent enough to at least order the attraction manager to supply them with barf bags so they don't throw up on one another.
- Foreshadowing: There are plenty to the Great Oni's true identity.
- The music that plays whenever they appear is Elisabeth Báthory's theme.
- Ibaraki makes multiple mentions that the Great Oni's policies and actions aren't really "oni-like" at all, being far too orderly. Which makes sense, considering Elisabeth's attempts to come off as a proper ruler, if still inept.
- The Great Oni's dialogue is structured in such a way that it comes across as someone trying and failing to be evil, particularly underlined by the weird childishness and care behind some of the proclamations. Again, not unlike Elisabeth's inept attempts to be a ruler.
- The fact Oniland strangely has a lot of Halloween decorations everywhere, yet there's not a single mention of Elisabeth Báthory, the headliner of every single Halloween event previously, at all from the story, even as a cameo.
- The massive parade that's held every night in Oniland's streets is capped off by the Great Oni bellowing to the sky, and Salieri mentions that the Great Oni asked him to of all things compose a musical accompaniment, to which he answered that even he couldn't manage something for that sort of noise. Oddly similar to most people's reactions to Elisabeth's singing...
- The Great Oni in combat has the [Dragon] Trait, particularly noticeable since the only other oni in the game at the time that has that trait would be Shuten and lending credence to their claims that they were never really an oni. They also do not have the [Male] Trait. Not to forget their name "Vermilion Dragon" serving as another hint. Elisabeth herself has the [Dragon] Trait and her pink hair is a dark enough shade that one could compare it to the color "vermilion".
- Hates Being Alone: Elisabeth JAPAN made Oniland because she didn't want to be all alone to sing by herself and wanted to see other people be happy, exacerbated by how in her amnesia she kept telling strangers she met she was an oni and they kept running away from her in fear, which made her desperate to have someone stay with her.
- Horned Humanoid: Fittingly for an oni, they have a pair of horns curling around their head. Even in her true form as Elisabeth JAPAN, her normal dragon horns have straightened and smoothed out to more heavily resemble oni horns, which probably helped make people mistake her for one, not at all helped by her own amnesia.
- Insistent Terminology: Her name is Elisabeth JAPAN, and she can tell when you don't give the second word all capital letters.
- Large and in Charge: The Great Oni surpasses all the other onis in height, including the large commander onis.
- Laser-Guided Amnesia: Elisabeth JAPAN really is Chaldea's Elisabeth Báthory, not an alternate one summoned elsewhere, but she's lost her memories of both of her time at Chaldea and even most of her own past due to the trauma of a shipwreck and has been brainwashed by the Kamuy's Gold even further.
- Make Me Wanna Shout: It's noted the Great Oni has an incredible roar and the force of it can easily blow people back and hurt them. Fitting, considering it's really Elisabeth, feared throughout Chaldea for her singing voice.
- Mistaken Identity: When Ibaraki finally confronts the Great Oni face-to-face, she starts to mock them for not acting at all oni-like, only for the Great Oni to shut her up and plainly state they're not actually an oni. It's just that everyone kept calling them one so they just rolled with it to make things easier.
- Motive Rant: Angrily rants that all they wanted was to sing and to entertain and make humans, oni, and even Heroic Spirits happy, and they refuse to hand over the Kamuy's Gold because without it Oniland would vanish.
- No Biological Sex: While the characters use masculine pronouns for the Great Oni, they don't actually have the [Male] Trait, thus Anti-Male Servants aren't as effective against them. This is to hide their real gender, since they are actually female.
- Orcus on His Throne: While the Great Oni shows up at the Main Street at the beginning, they simple let the attraction managers handle the heroes. Of course, the attraction managers all fail one after another. The heroes actually wait for the park's final event and fight them at that time, now already weakened from the massive lost of gold.
- Piñata Enemy: They are the Raid Quest boss of the Oniland event, dropping all three currencies, Magifender Points, a lot of QP, and a high chance of dropping Fool's Chains, Aurora Steel, Mystic Gunpowder and Cursed Beast Gallstones.
- Red and Black and Evil All Over: The Great Oni is completely red and black and they act like a Card-Carrying Villain.
- Signature Laugh: Gehehehehehehe! Gaaaahahahahahaha!
The Gold Servants are the attraction managers of Oniland who serve the Great Oni Vermillion Dragon. They are made of fragments of the Kamuy's Gold who copied the personalties and abilities of Chaldea's Evil-aligned Servants.
The manager of the merry-go-round is the Whip Oni Queen Medb. The manager of the spinning teacups is the Pirate Oni Blackbeard. The newly assigned managers of the food court are the Seafood Oni Gilles de Rais and the Hamburger Oni Jack the Ripper. The manager of the mirror house is the Murder Oni Hyde. The manager of the Ferris Wheel is the Wildfire Manager Salieri.
- Ax-Crazy: All of them to a degree, but most notably the Murder Oni and the Wildfire Oni.
- Bestiality Is Depraved: Whip Oni Medb gets a little too...intimate with the carousal horse, with everyone except Ibaraki getting flustered by her erotic playing with it and how she talks about all the ways you can "ride" them. And even Ibaraki is only unaffected because she's too clueless to get the innuendo, as she thought Medb was trying to eat it due to how she was working her mouth around it.
- Defeat Means Friendship: A variant of the trope is applied, as the defeat of the Gold Servants allows their originals to be freed from Oniland's power that traps them inside. Although they are already allied with the protagonist due to being Chaldean Servants, Blackbeard and Salieri eventually join the heroes in their hideout and provide you with information.
- The Dragon: The Wildfire Oni Salieri is the strongest of the Gold Servants, being made of a bigger mass of gold fragments than the rest. He's also the Vermillion Dragon's favorite Gold Servant who composes musical accompaniment for their songs.
- Dual Boss: Gilles and Jack are a duo and after their defeat, they return to their original form as a single gold fragment.
- Evil Knockoff: They are all copies of Chaldea's evil Servants, made out of the Kamuy's Gold.
- The Friend Nobody Likes: After Pirate Oni Blackbeard is defeated, the Great Oni admits they never really liked him in the first place.
- Has a Type: Blackbeard notes Assassin of Paraíso ticks many of his personal preferences and tries to flirt with her, and expresses shock that she doesn't immediately shoot him down. The real Blackbeard shares his sentiments.
- Hyde Plays Jekyll: Hyde pretends to be Jekyll and stabs the real Blackbeard in the back once they are alone. He tries to blame it on Columbus, Mephistopheles and the Phantom of the Opera, even though only Phantom would have been able to conceal his presence. Mephistopheles then instigates a fight and with Phantom's help they force Hyde to reveal his identity.
- In the Back: While pretending to be Jekyll and hiding his presence as a Servant, Hyde stabs the real Blackbeard in the back, although Blackbeard survives (thanks to his Guts).
- Quirky Mini Boss Squad: Since they are copies of Chaldean Servants, they also copied their personalities, only that they are more evil and crazier.
- Starter Villain: The first attraction manager the heroes fight is the Whip Oni Medb. After her defeat, the Great Oni monologues about how she's merely the weakest Gold Servant.
- Whip It Good: Medb's Weapon of Choice, to the point that she's actually named "Whip Oni".
- Antagonist Title: Of the Great Oni and the Golden Kamuy, with Moshirechik serving as the titular Golden Kamuy.
- Composite Character: Of Moshirechik Kotanechik and Fafnir; due to it being born of a fusion of Das Rheingold and Kamuy's Gold that gained sentience, assuming the name of Moshirechik before using the accumulated desire of Oniland's residents to become a golden Fafnir. In-game, he's just referred to as "Golden Dragon".
- The Dog Was the Mastermind: Who was expecting Shuten-Douji's Non-Human Sidekick to be the real mastermind?
- Greed: It eventually materializes as Fafnir, the embodiment of greed in form of a dragon.
- Hoist by His Own Petard: All the Chaldean Servants it manipulated in order to feed on their desires and grow stronger end up pulling a Big Damn Heroes moment at the end of the event now freed from its influence and handing it its scaly ass.
- I Am the Noun: Boasts that it is both the Kamuy's Gold and the Holy Grail, which isn't a fabrication since they're technically all one and the same.
- One-Winged Angel: From a Non-Human Sidekick not out of place in a magical girl series as a mascot to a giant golden Fafnir. Lampshaded hard by Shuten-Douji, who notes it had one hell of a growth spurt.
- The End... Or Is It?: Shuten's Onicure form still has Haku even after the event. She claims it's just a mindless construct now, but teases not to be too surprised if you ever hear it talk. Her profile indicates that there is a rumor in Chaldea that it talks to itself when alone.
- Overly-Long Name: As noted in Composite Character, the dragon is made up of two beings. An ancient demon that tried to kidnap the Sun Goddess and eventually got outwitted by Ainu hero-god Aynurakkur, and the evil, greedy dwarf-turned-dragon Fafnir.
Christmas 2018 Holy Samba Night: Snowing Ruins and the Maiden Knight
- Battle Aura: Gains a black one upon merging with the pure concept of Santa Claus.
- Blood Knight: A given due to being made of the darker aspects of Quetzalcoatl.
- Enemy Without: Is this to both Quetzalcoatl and her (Samba/Santa) form. It's because she's this that she has an innate advantage against her "good" half, as they both still possess Quetzalcoatl's Authority and immunity to attacks from "good" people if weakened by their split, which is why Bradamante can still hurt Black Quetzal Mask, but this means the good Quetzalcoatl can't hurt her at all while the evil Black Quetzal Mask has no such restrictions.
- Fair-Play Villain: She wants to become the true Santa, but offers the heroes a chance of defeating her by letting them enter the Santa Tag Team Tournament even if she could just kill them there and now. She also tries to make the matches fair for the tag teams by keeping their identities a secret from each other so that the matches come down to actual strength instead of who has more intel of the other. Of course, once Quetzalcoatl (Samba/Santa) and Bradamante make it to finals and prove they actually have a shot, she stops playing fair and pulls out a double whammy of cheating.
- Graceful Loser: Despite being willing to go This Cannot Be!, she accepts her loss to Bradamante and remerges with her good half without a struggle.
- Hopeless Boss Fight: The first fight against her ends once you drop her first health bar, and in-story ends with her victory.
- Kneel Before Zod: She tells Bradamante to do this, acknowledging her as the true Santa, and in return she will grant her heart's desires. Bradamante refuses.
- Laser-Guided Karma: She insults the past Santas as being effectively cheap imitations and unworthy of being the true "pure" Santa Claus. Those very same Santas lend their power to Bradamante to give her the purity and strength necessary to hurt and defeat Black Quetzal Mask, and even better it was only possible because she decided to livestream the match so that they found what was going on.
- Loophole Abuse:
- Because she's Quetzalcoatl's Enemy Without, she retains the goddess' Authority over "good" aligned entities that renders her immune to their attacks. While the split has weakened this to an extent, which is why Bradamante can hurt her, this makes her immune to attacks from her good counterpart.
- Her partner in the tag-team tournament is actually the magical energy of the Christmas Grail extracted to obtain the "pure essence of Santa Claus" and shaped in the rough shape of a human. It can't actually fight on its own and always stays on the sidelines while she fights alone, and it's purpose is to perform a Fusion Dance with Black Quetzal Mask to empower her.
- No-Sell: Alongside possessing Quetzalcoatl's immunity to attacks from Good-aligned entities, if weakened, when she merges with the pure concept of Santa Claus extracted from the Christmas Holy Grail, she gains the concept of "Santa Claus is a giver of gifts, not a target to be attacked" rendering her immune to all attacks that don't come from a just as pure Santa. It takes Bradamante absorbing the power of the other Santas to gain the necessary purity to pull it off.
- Pure Is Not Good: The pure essence of Santa Claus extracted from the Christmas Grail resembles a Shadow Servant, and when merged with Black Quetz Mask gives her a black Battle Aura.
New Year Event 2019 - Sparrow's Inn Activity Log: Chronicles of the Prospering Enma-Tei
The villain of "Sparrow's Inn Daily Report - Records of the Enma-tei's Prosperity" event, his various tricks were running Beni-Enma's inn into the ground until Chaldea dropped by.
- And I Must Scream: His final fate as per Beni's judgement: he'll be sent to the Sañjīva, Kālasūtra, Mahāraurava, and finally the Avīci Hot Hells of Naraka. Sañjīva is the "Reviving" Hell, with a ground of hot iron and with guards that mercilessly beat you to death, constantly reviving you once you "die". Kālasūtra is the "Black Thread" Hell, which includes all the punishments of the Sañjīva Hell plus lines being put across your body to show where you should be cut with saws and claws. Mahāraurava is the "Great Screaming" Hell where you're eaten alive by beasts for eternities. Finally, Avici is the "Uninterrupted" Hell, where people are burned alive for entire lifetimes. It's also worth noting that all Buddhist Hells last for bagillions of years to the point that you'd likely face the heat death of the universe before you manage to leave one of them! In short, the Nue (or just the Moneyed Monkey) will be facing many punishments for eons to come.
- Barrier Change Boss: During the battle against it, it will apply Evade/Invincibility that reduces damage from a certain card type each turn.
- Bitch in Sheep's Clothing: All of the disguises indulge in some level of niceties, though Moneyed Monkey fit the bill the best as he always puts up an affable front as a long time guest enjoying his time at the inn and offering Chaldea some advice. He also never engages in the shady actions of Chief Snake, the random rampages of Magistrate Tiger, or the attempted Moving the Goalposts of the Bamboo Cutter, but he's just as guilty of taking advantage of Beni-Enma's generosity and trying to steal the inn out from under her as the other parts of his identity. Ironically, it turns out that while Tiger and Snake eventually started having misgivings about their actions, Monkey always intended to screw Beni-Enma and calls them both out as soft-hearted.
- Camp Gay: Chief Snake really has a thing for Goredolf and thinks he's handsome. The fact that Goredolf took the heat for him when they ended up opening the Tribute Box just added to that.
- Composite Character: Beyond just being the Nue, the Moneyed Monkey is the same monkey from "The Quarrel of the Monkey and the Crab", a story of a sly monkey who killed a crab after tricking it, only to be killed by the crab's offspring. He is not, however, related to the monkeys from the "See no evil, hear no evil, speak no evil" Japanese proverb and gets pissed at being compared to those "exhibitionists".
- Death Equals Redemption: The tiger and snake both abandon the monkey after the boss battle against the Nue, as both of them no longer had any desire left to torment the Enma-tei. Consequently they ascend and avoid the fate of the monkey.
- Degraded Boss: Only over a month after debuting, his sprite is recoloured and loses his mask into the "Tarnished God" enemy which occasionally appears as a mid-boss.
- Defiant to the End: Monkey refuses to apologize for his actions or make any attempt to justify himself outside of For the Evulz, and in fact scorns both Tiger and Snake for having their own Heel Realizations and abandoning him while cursing Beni-Enma and Chaldea to the bitter end as he's sentenced and Dragged Off to Hell.
- Dragged Off to Hell: As punishment for his crimes of manipulating her, making her pay off an unpayable debt for 500 years, planning to take over the Enma-tei and feeding her sparrows to the Tiger, Benienma promises him that he'll be cast into the Sañjīva, Kālasūtra, Mahāraurava, and finally the Avīci Hot Hells. She delivers on it when you beat him, at least on the remaining Monkey as the Tiger and Snake have left and had at least a Heel Realization.
- For the Evulz: The entire reason he attempts to take over the inn, causing Beni-Enma no end of hardship over 500 years and forcing her to pay a debt she has no way of getting back? For fun.
- Freudian Excuse Denial: Beni-Enma tries to guess why the Moneyed Monkey tried to do all the things he did, was it as revenge to what happened in "The Quarrel of the Monkey and the Crab", or due to him becoming the Designated Villain of other tales even though he was trying to live his life, only for him to laugh her off and say that he did everything because it was fun.
- Genre Savvy: He knows that Chaldea has several Servants who could instantly curb-stomp him so he put up a successful barrier to keep them away from the inn. Not that it helps him when the jig is up and Chaldea still kicks his ass, especially since Beni-Enma herself has class advantage.
- Good Is Dumb: The Nue believes this, even admitting that he loves conning good, honest people.
- Heel Realization: Both Tiger and Snake had theirs during their time at Enma-tei, with the former having fallen into it over time and feeling sorry for Beni-Enma and the latter touched by Goredolf's kindness to him during Chaldea's stay. As a result, they both abandon Monkey during the final battle.
- Hybrid Monster: In this case, "hybrid" is literal because the monkey, tiger, and snake parts of the Nue are all their own entities and can split off.
- I Take Offense to That Last One: Moneyed Monkey really doesn't like being compared to those "exhibitionist" monkeys of the "See no evil, hear no evil, speak no evil" proverb.
- Jerkass: Nue's pranks and tricks have been ruining Beni-enma's inn for no reason other than he thought it would be fun (and because he was interested in eating all the sparrows).
- Malevolent Masked Man: Three of his four disguises all wear different masks with the exception of the Bamboo Cutter, and of course, the Nue himself wears one in his true form, and he's quite frankly a Jerkass.
- Master of Disguise: He's capable of disguising itself as pretty much anything, up and including different characters at once with different appearances and personalities, which is how he's managed to run circles around Beni-Enma for so long.
- Maximum HP Reduction: The Tiger's Rage skill gives Nue this as an on-hit effect. It double as an Armor-Piercing Attack against an insufficiently-damaged target, since it will hit right through defensive effects.
- Moving the Goalposts: Bamboo Cutter does this constantly. He's constantly upping the debt for priceless items that it turns out he never even really owned to the point where Beni-Enma is just struggling to pay the interest, and when Chaldea is able to get approximations of the items he claims he lost, everyone is aware that he'll demand the actual items, not ones that are the same. As such, Fionn has the Chaldean team set up a con where he's forced to admit to his guilt.
- Nice Job Fixing It, Villain: It was Chief Snake who tricked Goredolf into opening the Tribute Box and releasing the stored gratitude, although ironically Snake did it without Monkey's consent and by accident. In doing so, the Nue sets up the chain of events that leads to the inn's renovations by Chaldea's hands and revealing his own duplicity of Beni-Enma.
- Poisonous Person: The Snake's Rage skill allows Nue to drop both a party-wide Poison and Corroding Poison status effect for five turns, which combined with its ability to cause Maximum HP Reduction can kill a Servant surprisingly fast.
- Public Domain Artifact: The five treasures the Bamboo Cutter claims he lost at the inn are the very same ones from The Tale of the Bamboo Cutter that Kaguyahime desired her suitors to find. Of course, as he's not actually the bamboo cutter, he just lied to con Beni-Enma. Chaldea actually manages to collect all five treasures (or in the case of the fire-rat robe, a close approximation of it) from the various Heroic Spirits visiting the inn, and they use them to trick the Nue with a con of their own into revealing his deception to Beni-Enma's face.
- Purple Is Powerful: It has a noticeable purple tinge to its body, and it's the main difference (aside from the loss of its mask) against the Corrupted God (which has a red tinge).
- Walking Spoiler: The story's climax reveals that he was masquerading as four separate characters (Moneyed Monkey, Chief Snake, Magistrate Tiger, and the Bamboo Cutter), serving as his extensions to slowly tighten his grip on the inn.
- Yōkai: He is the legendary Nue, having used his shapeshifting to con Beni-Enma for years on end. Interestingly though, this Nue is technically three separate entities split between the monkey, tiger and snake who can split apart and recombine as they see fit, but all have their own wills despite being nominally united.
- You Will Not Evade Me: Upon breaking its first Break Bar, the Nue will apply Sure Hit at the start of each turn alongside its new random-card Invincibility buff.
Valentine 2019: Voice & Letter Collection ~Murasaki Shikibu and the 7 Cursed Books~
- Clipped-Wing Angel: All cursed books start off as demons or monsters, but once the first bar breaks, they're reduced to their book state.
- Me's a Crowd: By absorbing enough magical energy, the books can split up and create copies of themselves, which in turn can repeat the process. However, if the original is defeated and sealed, the rest will follow suit.
Lady Reines' Case Files
Mnemosyne is the main villain of "Lady Reines' Case Files". One of Chaldea's secondary computer systems that had gone unused for several years, its activation kickstarts the event after it learns of everything that had happened since its construction, creating the Patchwork London Singularity from the protagonist's memories.
- Adapted Out: In Fate/Grand Order Arcade, the plot still being in the "Observer On Timeless Temple" arc means that Mnemosyne is absent on its version of "Lady Reines's Case Files", with the fault of the Singularity being on Rhongomyniad itself.
- Batman Gambit: In order to implant the Fake Memories, it first had to give the protagonist Laser-Guided Amnesia, then plant various "Mnemosyne" paper scraps around the Patchwork London containing those memories. The first two would be identical to the real memories, getting the protagonist to lower their guard, while the third would be the first total fabrication and start of the proper process. To faciliate this, it also impersonated Mash to make it seem like Chaldea was in contact and encouraging the process. Were it not for El-Melloi II's interference, it would have worked perfectly.
- Enemy Summoner: It will summon a Shadow Servant of da Vinci to aid it in combat, and will summon another one everytime it's defeated.
- Even Evil Has Loved Ones: Downplayed in that the AI is more of an Anti-Villain than an outright evil AI, but Mnemosyne grieves over da Vinci's death, and part of the reason why this event came to be is because of that grief.
- Fake Memories: The crux of its plan, implanting these into the protagonist to remove their possible trauma.
- Let Them Die Happy: Reines does this for Mnemosyne as they leave it in the Collapsing Lair, using her Noble Phantasm to show the AI a vision of da Vinci telling it a job well done.
- Love Is a Weakness: Mnemosyne clearly cares about da Vinci as part of the reason why the AI tries to do what it did during the Lady Reines Case Files event is because it also misses da Vinci. However, as shown with Reines' Noble Phantasm which exploits weaknesses of enemies, da Vinci happens to be Mnemosyne's weakness.
- Meaningful Name: The system is named after the Greek goddess of memories. Fittingly enough, their grand scheme involves altering the memories of the protagonist to forget about their possible trauma.
- More Dakka: It fights using turrets that shoot bullets which bounce all over the screen.
- One-Letter Name: Waver's "death" warning was the letter M. He was actually referring to "Mash", as in the fake Mash Mnemosyne disguised itself as.
- Psychological Projection: Part of the reason Mnemosyne chose its method of Fake Memories and Laser-Guided Amnesia is because it also wants to forget its traumatic memories, specifically those of da Vinci's death and its inability to properly come to terms with the grief associated with it. When the protagonist refutes forgetting their bad memories, Mnemosyne is utterly confused at why they would want to keep them.
- Stone Wall: Its AoE attacks don't do much damage on their own, but Mnemosyne has a special DEF buff that reduces all damage to the point even Servants with Bonus Damage are hard-pressed to deal lasting damage with methods that don't involve stacking massive amounts of offensive buffs while dropping various defensive debuffs on it. That's on top of Mnemosyne having three health bars, dropping NP Drains with each Break Bar, her NP removing all buffs before dealing damage, and summoning a Shadow Servant to drop extra muscle.
- Rogue Drone: There was at least one part of Mnemosyne's collective consciousness that didn't approve of the AI's plan, and decided to take the physical form of Protagonist's lost memories into the Rail Zeppelin and hide inside Faker's Spirit Origin.
- Well-Intentioned Extremist: All it ultimately wanted was to help the protagonist in their quest against the Lostbelts. Unfortunately, its methods went into overkill to help them process their memories and possible trauma in response to its own repressed trauma.
All-Out Nobunaga Assault ~ GUDAGUDA Final Honnoji ~
- Attack of the 50-Foot Whatever: Big Nobbu, a sentient Nobbu that leads the Nobbu. Even wears a B button to signify this. Despite this, Big Nobbu isn't one for combat.
- Big Bad Wannabe: Most of the antagonistic Nobunagas are this, but the most notable examples would be Kaiser Nobunaga (who commands an army of advanced weaponized soldiers as well as several Brainwashed and Crazy Servants, and is the most threatening of the first three Nobbus faceable in Big Nobbu, herself, and Kipposhi, but is ultimately defeated and the only one killed) and Real-Deal Nobunaga (actually sends Chaldea running at first, only to fall to a Clean Food, Poisoned Fork plot by Nobukatsu before Nobukatsu ends up screwing things up himself). Even Demon King Nobunaga herself, set up as the Arc Villain, is really just a Disc-One Final Boss to the High Priest of Makuzu.
- Historical Gender Flip: Averted by Real-Deal Nobunaga, who, as the name suggests, is the "historical" Nobunaga and thus male. This sends Chaldea into confusion and Chaldea Nobunaga into something of an identity crisis, with the latter proclaiming he must be an Alternate Self from a Lostbelt.
- Pieces of God: In a way, all of these versions are components that make up Avenger Nobunaga.
- Allohistorical Allusion: While likely existing as separate characters in this continuity, Makuzu's characterization harkens to negative/less-sympathetic portrayals of the Buddhist leaders that opposed Nobunaga during his period of conquest: Rennyo (the head of the Hongan-ji who harassed Nobunaga up until Mt. Hiei), and his successor Kennyo/Kosa, who allied with Nobunaga's rivals.
- All There in the Manual: While his motives are vaguely hinted in the event, "A Demon and Human" story from Koha-Ace is implied to be about his backstory, as it tells a story of a man who had lost his faith in gods and Buddha when everything he had got swallowed up in flames right before meeting Maxwell's Demon. The man aimed to get the Holy Grail in order to bring happiness to everyone if no god or Buddha existed, only for the Grail to give him the high-efficiency magic converter that is the true nature of Maxwell's Demon's Noble Phantasm. When Maxwell's Demon tried to apologize for deceiving him, the man tells him that everything's fine with a Slasher Smile, possibly leading to the events of the Final Honnoji event.
- Blob Monster: What he creates as Mooks from his Perpetual Motion Machine.
- Nay-Theist: While he sees Lord Makuzu as a god-like being and discusses Kagetora's ties with Bishamonten, he is very adamant on believing that there are no gods or Buddha in this world due to something that happened to him. He is rather surprised when Demon King Nobunaga starts lecturing him on how the potential all humans have is the true face of the gods.
- Punny Name: Makuzu is a pun on Max(well), which comes into plays as Maxwell first introduces himself as Makuzu's/Max's Caster before revealing himself much later.
- Utopia Justifies the Means: His Goal in Life is to create a post-scarcity world where everyone has peace and plenty and no one has to work hard just to survive. Even setting aside the stagnation and lack of drive this creates in the people, or the corruption of his own warrior monks, it's literally fueled with escalating Human Sacrifice of children, and it's pointed out the buildup of material debt would eventually cause the entire singularity to be sacrificed and move on to the real world.
- Well-Intentioned Extremist: Kagetora notes that he is able to see her halo when she channels Bishamonten, suggesting that despite his certainty that the gods don't exist and the insanity of his actions, he's still Buddhist in some sense, if a corrupted and fallen one. And his plan does hinge on a certain kind of detached compassion for humanity as a whole, if not for humans as individuals.
- Would Hurt a Child: Hurt a child? He's using kids to be basically sparks to ignite his Perpetual Motion Machine black giant maker, and he brushes off the fact he has to escalate their usage to keep up with his demand.
Summer 2019: All In! Las Vegas Championship Match ~ Seven Duels of Swordbeauties!
- Summer Lion King is not the last Swimsuit Swordsmaster faced. That would be Miyamoto Musashi's evil doppelganger, Heavenly Demon Musashi.
- In the Part II of the event, not only does it come clear that the Seven Duels of Swordbeauties have been around much longer than the Grand Canyon Singularity, but the casino managers had nothing to do with the tournament in the first place. They were all just taking advantage of the existing matches.
- Brainwashing: Summer Jeanne uses a technique called the "Big Sister Beam" that causes those struck by it to start thinking of her as their big sister. In addition to making the protagonist offload all of their buffs onto her, she uses it on Jeanne Alter and Santa Lily to make them think she's their big sister too.
- Demonic Possession: MEDJED is a result of Assassin Nitocris's Divinity going into overdrive, causing her Medjed's aspect of her to take command of her body while the actual Nitocris is comatose.
- Denser and Wackier: To Shimousa's Swordmasters, of whom they are a parody. These are played more for comedy than drama, and their madness is silly rather than terrifying.
- Drunk with Power: All of them have their powers augmented significantly within the singularity they're in charge of with a significant dose of madness added in to various degrees. The only way to snap them back to reality and lose that excess power, would be to experience the shock from ''losing'' for the first time.
- Fisher Kingdom: Downplayed, but still there. Each Swimsuit Swordsmaster commands a casino that is based off of them. For example, MEDJED commands an Egyptian casino complete with sphinxes as security guards and has workers based on Medjed. Suiten-gū Leviathan, a water show casino based off of Seraphix, is commanded by Mysterious Alter Ego Λ.
- Non-Indicative Name: Despite being called "Swordsmasters," only Musashi and Okita J. Souji use swords. Osakabehime uses firearms though she talks to herself how she has few sword legends tied to her, MEDJED uses Egyptian magic combined with unarmed strikes, Mysterious Alter Ego Λ doesn't have her bladed heels with her and just uses simple prosthetic, Jeanne d' Arc commands sharks to attack with and Summer Lion King is a Death Dealer.
- The Sixth Ranger: Even though the tournament is called Seven Duels of Swordbeauties, there are only six official Swimsuit Swordmasters. Summer Lion King figured that we would come across a seventh Swimsuit Swordmaster, which we do thanks to Okita J. Souji.
- Threatening Shark: This Summer Jeanne, in addition to her dolphins and whales, controls an enormous and dangerous great white shark.
- The Worf Barrage: Once the protagonists, using the logic that a mother outranks a big sister, recruit Summer Raikou to their side, Summer Jeanne is easily dealt with, as Raikou first counters her Big Sister Beam with a Mother Laser, then throws her shark so far away it becomes A Twinkle in the Sky.
- Determinator: As she represents Musashi's refusal to lose to non-swordsmen, one of her passives outright gives her Special Defense against non-Saber damage seemingly based on nothing but this stubbornness.
- Enemy Without: Is this to both the original Miyamoto Musashi and her Berserker forms.
- Literal Split Personality: This Musashi is what split off after her original Saber self messed with a Holy Grail, which is her her duel-craving Arrogant Kung-Fu Guy personality who refuses to lose to a non-swordsman, with none of the positives.
- The Stoic: She's essentially Musashi's desire to fight powerful swordsmen manifested without any of her actual personality, which is why she spends most of her time glaring and speaking seriously.
- Walking Spoiler: Her existence is revealed to be the true source Las Vegas Singularity, and why Musashi schemed with Merlin to start the Seven Swordbeauties contest in order to find a swordsmaster strong enough to defeat her.
Battle in New York 2019
- Call-Back: Additionally, "Ishtar With Demon Thorn Tattoos On Her Arm" was a thing during "Christmas in the Underworld".
- Cassandra Truth: Despite the UFO, almost nobody actually believes her when she calls herself an alien from another world and think it's just their Ishtar on another power trip having acquired some weird relic that becomes a UFO. It's not until she's beaten and fades away, plus the actual Ishtar showing up, that they realize she was serious.
- Foreshadowing: Her presence in "Battle Of New York" foreshadows "Saber Wars II", particularly with how upon her Break Bar in her fight, she Class Changes to an Avenger, the very class the playable Space Ishtar would debut in.
- Greed: She is Ishtar, after all. She announces she's come to Earth to plunder our treasure, uses beam attacks that turn people into gemstones, and wants the rare treasure called "Master."
- Mind Screw: Turns out that this is another version of Ishtar. What is their connection? Nobody knows. Made worse with the reveal of the actual Space Ishtar, who looks and acts nothing like this version.
- Recycled In Space: It's Ishtar with a giant UFO. She might be from the Servant Universe, where everything is a space parody, but it's never really explained. The existence of the actual Space Ishtar only complicates things more.
- Unreliable Narrator: Mysterious Heroine XX implies that she might actually be the Ishtar of the Servant Universe, the Red Devil she once defeated during her adventures and forced to become a better person. It's certainly a possibility, but it could just as easily be her mistaking her own universe's Ishtar for Space Ishtar, just as the protagonists do.
Saber Wars II
- Amulet of Concentrated Awesome: The Saber Badges that they have been distributing can turn anyone wearing them into Sabers.
- Bait the Dog: Warrior of Darkness Munenori is introduced as Ashtart's silly but lovable father figure, who isn't afraid to make a few jokes about how hard she tries to be evil. He seems like he cares deeply for her in his own way. Then it turns out he was the one who murdered the professor to kidnap her as an infant... and then he stabs her himself after she loses the battle with the protagonists, planning to use her as a human (or Servant) sacrifice to awaken Astaroth Origin, and admits that while he cares somewhat for her it was mostly as a means to see his sword-style attain fruition, not as a person.
- Blood Knight: Sigurd is this. He sees no worth in the Servantverse because the dragonkin are gone, depriving him of a Worthy Opponent. Ironically Mysterious Heroine X IS a dragonkin and beats him. It's also implied by X that having never met Brynhildr or fallen in love with her means that combined with his immortality his Blood Knight tendencies were literally all he had left.
- Cool Starship: Dark Maanna, a giant Flying Saucer that acts as Ashtart's headquarters. As well as a replica of Ashtart Origin's own shrine.
- Dean Bitterman: Xiang Yu is running Queen's High School into the ground and sending troublesome students to reeducation camps, though from his perspective he's doing his best to protect the students.
- Disappeared Dad: Lancelot implies he's working for Space Shinkageryu just to get away from Galahad who's in a rebellious phase.
- The Dragon: Warrior of Darkness Munenori is this to Ashtart in leadership of the Space Shinkageryu, while Sigurd plays this role to Munenori himself as the strongest and leader of the Six Blades who's in on and fully onboard with Munenori's true scheme.
- Fallen Hero: Sigurd was one of the Servants who defeated Ashtart Origin 2000 years ago, nowadays he's part of the Space Shinkageryu and is trying to AWAKEN Ashtart Origin.
- Irony: Anastasia, whose main power is ice manipulation, hates the cold since she has been stuck mining Big Blue Tank in near-absolute zero climate with no one to talk to.
- Knight of Cerebus: Although he looks to be a simple Cloudcuckoolander's Minder for Ashtart to begin with, Dark Munenori quickly turns into one of the darkest, most vile scumbags in the entire Servantverse - once the revelations of his past deeds come to light, the story starts treating him less as a gag villain and more like a legitimate, morally bankrupt individual.
- Load-Bearing Boss: When Anastasia is defeated, she hits the mining facility's self-destruct button and then escapes, leaving the heroes on a mine collapsing into a gas giant's core.
- Not so Above It All Warrior of Darkness Munenori's first appearance in has him wearing his full samurai get-up, including helmet and mask...and communicating via Vader Breath vocalizations, admitting after being told to take it off he couldn't help himself. And according to Ashtart, this is something he has done repeatedly and continues to do so even after she tells him to stop.
- Obfuscating Insanity: While Lancelot acts out like what you would expect from the Berserker version of him, him being called out by Heroine X makes him drop his berserk act in order to save face and leaves Maanna alone.
- Punch-Clock Villain: While some of the Six Blades, like Sigurd, are true believers and full-on nihilists, others like Anastasia, who wanted to reclaim her status; Billy, who got roped in after being captured by the Shinkageryu; and Beni-enma, who only joined to avoid financial collapse, are definitely not as evil as their organization would imply.
- The Remnant:
- Lancelot used to be a member of the Dark R.O.U.N.D.S. before Ex threw him out into space after he lost a duel against her. The rest of the members are somewhere else enjoying their new lives such as Gawain being a chef in the Green Kitchen.
- Sigurd is one of the last two members of the Servant team that originally defeated the Primordial Goddess, with the other being Calamity Jane.
- Who Wants to Live Forever?: It's heavily implied that Sigurd's cursed immortality and watching the galaxy change over 2000 years on top of never having met Brynhildr is what convinced him to aid Space Shinkageryu in bringing Ashtart Origin back so he could lift it.
- "Forgetting me is evil. Changing one's beliefs is evil. Moving to a new land is the gravest insult one can give a goddess."
- Duel Boss: The final battle against her where she retains her very high HP bar, but this time she is pitted against a beefed-up "Ishtar Ashtart" as a Mirror Boss.
- Dying Curse: The first time she was beaten, she cursed the two surviving Servants that beat her Sigurd and Calamity Jane with immortality that wouldn't end until she returns. 2000 years later and Sigurd decides to aid Space Shinkageryu in doing so, while Ashtart Origin upon noticing Jane afterwards almost nonchalantly lifts it.
- Dying Declaration of Hate: Unable to accept defeat at the hands of her heart, she vows that no matter what she will return and have her vengeance.
- Evil Cannot Comprehend Good: It's part of her basic nature that she will always seek to destroy the current universe, down to the last atom, because it took away her old universe. Taking a land from the goddess protecting it, in the Origin Universe, is tantamount to taking away a goddess's very reason for existence as well as their power and authority, so even though Ashtart and Space Ishtar disagree with her on a fundamental level, she won't - and likely can't - ever reconcile over how to handle the newer Servantverse.
- Genius Loci: Her actual body is literally the Origin Universe, and only similarly large scale attacks can harm her.
- Her shrine, also, is literally her collective body. As explained in the Goddess Scriptures, the Origin Universe did not differentiate between a goddess and the land they cared for, so any shrine made for her in earnest is literally her and vice versa.
- Hopeless Boss Fight: Her first battle where along with more than a million HP, she goes with permanent invincibility. And even if you try to chip away at her with Pierce Invincibility, then it turns out that she is impervious to damage regardless.
- Madness Mantra: Once Ishtar Ashtart shows up she starts to lose it, repeating "It can't be!" over and over.
- Negative Space Wedgie: Due to her sheer scale, on top of her literally being an intelligent representation of a previous universe/galaxy, she could be considered a sapient version of this.
- Omnicidal Maniac: While she's good at hiding the "maniac" part, she is absolutely hell-bent on destroying literally everything that exists in this new universe - the Servantverse - in one giant fit of rage at the loss of the Origin Universe. When the resistance against her shows promise at actually stopping her, then she begins to unravel.
- Pieces of God: She's the body of the Origin Universe, while Ashtart and Space Ishtar are halves of her heart that was torn out long ago.
- Superpower Lottery: In terms of pure power, she's very likely one of the strongest beings who's ever appeared in the whole franchise. She's a primordial goddess whose very body is a literal galaxy, only capable of truly being harmed by attacks of at least planetary-level destruction. It took an elite team of seven Servants backed by a Master to beat her the first time around, which they only managed by locating a weakpoint, and all but two perished in the end. When she revives, it takes Ashtart and Ishtarin merging into the similarly-powerful Ishtar Ashtart and once again pinpointing the weak point in her body to take her down.
- Suspiciously Similar Substitute: To Tiamat/Beast II, for essentially being the Servant Universe's "Mother", and attacking them for abandoning and forgetting her.
- Time Abyss: She's at least 5 billion years old. A god's perception of time is much longer though, so for her 5 billion years might as well be 5 seconds.
- Villainous Breakdown: Really starts to lose it once Ishtar Ashtart shows up and AGAIN when they prove superior in battle despite a draw being the only possible conclusion normally.
- We Can Rule Together: She offers Ashtart and Space Ishtar the opportunity to return back to her and become whole again. When they refuse, she brushes it off and says she'll just make a new heart as a replacement.
Valentine 2020 A Not-So-Ordinary Valentine ~Murasaki Shikibu and the Five Slaying Queens~
- Flanderization: Self-admitted, as Rokujou notes she's the perception of the person Murasaki judged Sei Shounagon to be and thus many of her negative traits are ramped up to malicious levels. Of particular note is her hatred of Murasaki, whereas the real Shounagon considers all of that water under the bridge.Nagiko: Ohh, I get it. So this is how you saw me, huh, Kaorucchi? "A smug and conceited woman who considers herself the gods' gift to the world." Man, no wonder you threw all that shade at me. I look like a total bitch.
- One-Winged Angel: Transforms into a Massive Ghost for the final battle.
- Other Me Annoys Me: It likely didn't help that Nagiko made her entrance by flying kick that knocked her away, but Rokujou really doesn't like her actual counterpart, calling her "that obnoxious latecomer party girl". She also really doesn't like her airheaded attitude or the fact that she's let go of her hatred.
- The Power of Hate: This version of Sei Shounagon is defined by her hatred for Murasaki and everyone who profited from the death of Lady Tenshi, admitting that she can't let her grudge go and that she'd gladly destroy the dreamworld with herself and everyone in it just to get at Murasaki.
- Tulpa: She's the manifestation of the Sei Shounagon Murasaki always imagined her to be. Rokujou noticeably revels in this fact, rubbing in to Murasaki's face that she's just doing everything she thought the real Shounagon would do.
Fate/Requiem Échiquier de l'Apocalypse
A version of Marie Antoinette who manifested through the Dread Spirits inside Utsume Erice. She is the main antagonist of the "Board Games of the Apocalypse" event.
- Accidental Truth: In a sense. Marie Antoinette herself does state that Dark Marie is pretty close to what she would be like should she be summoned as an Avenger. Which is impressive in a way, since she's solely based on Erice's projection as to what an Alter version of Marie would be like, which Dark Marie tries to throw in her face before Marie intervenes.
- Alpha Bitch: Her overall attitude, befitting common perceptions of Marie Antoinette.
- Alternate Self: Erice thinks that she is Marie Antoinette Alter but Dark Marie rejects the notion as she was created from Erice's interpretation of Marie, saying that a moody teenager like her would have no idea what the true Marie was like. However, the real Marie quickly butts in to say that Erice's interpretation of her is rather close to what an Avenger version of her would be like.
- Bitch in Sheep's Clothing: For most of the event, Marie is acting unusually cold and uncaring despite sporting the same cheerful demeanor she always has. At first it's thought to simply be that she's just really good at playing Werewolf (1997), but then the act keeps going even after the game ends...
- Enemy Without: While initially mistaken for an Alter of Marie Antoinette, Dark Marie reveals she's actually a Merger of Souls formed from Erice's Dread Spirits that have lived inside her all her life. As she herself states, she is Erice in a sense.
- Evil Costume Switch: As a potential Avenger version of Marie, she noticeably wears a darker and skimpier dress than Marie does, including a Cleavage Window showing of her rather large bust.
- Evil Doppelgänger: In a sense, since she's based off of Erice's idea of what Marie Antoinette Alter would be like rather than the genuine article. For her share, though, Marie herself does say that she's not too far off the mark.
- Fanservice Pack: She's much more stacked than her Rider self.
- Foreshadowing: There are few hints to show that the Marie you meet isn't exactly the Marie you know:
- She knows who Erice is even if she isn't able to explain why she does that. Marie obviously wouldn't know who Erice is, but her son Louis XVII definitely would.
- Voyager is almost instinctively wary around her and often moves away when she tries to be friendly. While one might chalk it up to Voyager being ill-equipped for human interaction, he has no problem around EMIYA Alter despite the latter's downer attitude, something that Marie notes with annoyance and envy.
- In the Werewolf game, it is established that one of the roles in play is Fanatic, a Villager who is working to let the werewolves win. However, due to how the game absurdly gets ended with the game master Jeanne dead, it isn't initially revealed who the Fanatic was. Indeed, Dark Marie was actually the second Werewolf, while Amadeus seemingly was the Fanatic.
- Speaking of the Werewolf game, Sanson randomly accuses her on the second day when nobody has any reason to suspect her at the time.
- The fact that Marie never once shows up as a Story Support Servant prior to The Reveal is suspicious. After all, this Marie is an Avenger and not a Rider.
- Merger of Souls: Strictly speaking, she's not actually a "Marie Alter", but rather an amalgam of the Dread Spirits inside of Erice that took on the form and identity of Marie Antoinette as Erice herself invisioned her. It would actually be more accurate, as she notes upon The Reveal, to call herself a version of Erice.
- One-Winged Angel: Similar to Ereshkigal in Babylonia and Ashiya Douman in Shimousa and Yuga Kshetra, she transforms into a Huge Ghost to fight the party with the Avenger class.
- Person of Mass Destruction: As the source of the out-of-control Dread Spirits, she's capable of drowning a whole city in the spirits, to the point a large number of Chaldean Servants run themselves ragged just trying to keep the tide back.
- Spotting the Thread: When she is finally outed, she first entertains the notion of simply being an Alter version of Marie, until she starts tormenting Erice over her killing of her son Louis. Her Avenger-class son Louis, summoned as a Servant in the backstory to Fate/Requiem - something no version of Marie would have any way of knowing. That's the point where the other characters quickly notice that she is not what she claims to be.
- Widow's Weeds: The real Marie says that what Dark Marie is wearing is her mourning dress, likely the one she wore during the French Revolution.
- Would Hurt a Child: She has no issues cursing someone like Illya without hesitation if it gets the attention she wants, and then there's her ultimate intent for Erice.
- You Have Outlived Your Usefulness: Her reason for killing D'eon, Gilles and Sanson in the Werewolf game is because they're conflicted at having to give up their roles as knights if it means they would play the game. If they won't be knights and won't support her, then they're no longer useful and have to be dumped immediately. This also goes for people who serve her faithfully, like Mozart who aided her in game, saying that naturally anyone who serves the Queen should be ready to die for her.
- You Will Be Assimilated: As she is the manifestation of the Dread Spirits within Erice that want to consume her soul if she won't keep them at bay with victims, her end-goal is to drive Erice into despair before absorbing her.
The Great Ancient Shinsengumi Legend GUDAGUDA Yamataikoku 2020
An evil spirit that according to legend was an ancient enemy of Yamatai, once a sorcerer that tried to conquer Yamatai after usurping his own kingdom. Serves as the main instigator of the "GUDAGUDA Yamataikoku 2020" event summoning Serizawa Kamo, having him attempt to destroy the rebuilding civilization of Yamatai.
- BFS: Has one lodged through his skull. Serizawa's Charge attack when with Kukochihiko has him pulling the sword out and attacking with it.
- Demonic Possession: Of Serizawa Kamo at the climax of the event, and intentionally on Serizawa's part since his initial master-stroke fell through.
- Dark Is Evil: It is an evil spirit who relishes in spreading darkness and devastation and plans to doom Yamatai.
- Didn't Think This Through: It summoned Demon Lord Nobunaga as the sacrifice to release the Magatsu-Yami upon Yamatai. Apparently it never bothered to check who it was dealing with, as once Nobukatsu uses his Noble Phantasm to revive her from the dead, she handily kicks its ass, as she's tailor-made to kick the ass of gods.
- Non-Action Big Bad: He summoned Serizawa to destroy Yamatai, but for most of the event is unable to do anything else as a mostly powerless spirit of revenge who spends his time getting worked up, which causes an annoyed Serizawa to tell him to shut up and let him do his job. It takes a blood sacrifice and acculumated hatred before he can manifest properly, and even then he needs to possess Serizawa to do anything.
- Tragic Monster: He's a spirit of revenge, but only because the Yamatai civilization failed to save him and his. As he dies, he finally finds peace as Himiko purifies him.
Halloween Rising! ~The Queen of Sandstorm and the Apostle of Darkness~
- Composite Character: The Dark Young in Cthulhu Mythos are described as being living, leafless trees with hooves and tentacles for branches. While it does share the status of being related to Shub-Niggurath, the appearance draws more inspiration from Baphomet, being a demonic goat man most likely due to Shub-Niggurath actually not being involved at all in the ritual that summoned it..
- Demonic Possession: Of the Master of Chaldea themselves.
- Meteor-Summoning Attack: Dark Young's Charge attack has it summoning a small storm of magical meteors.
- Morphic Resonance: Due to it possessing the Protagonist's body, the fur pattern it has heavily resembles that of Chaldea Mystic Code.
- Palette Swap: Is an elaborate reskin of the standard Demon enemy.
- Skull for a Head: Since Molay used a goat skull as a mask to initiate the ritual, its head is that of a goat skull with swirly eyes.
Shōwa Kishin Project GUDAGUDA Ryōma's Close Call!
An evil god who some have called Αmanojaku; a being who will jump between people to bring out the negative emotions they harbor in the darkest corners of their heart. The god was sealed away in a shrine in Izumo providence, but it was able to lure a shrine maiden-in-training to free it, destroying the village in progress and running off to spread more chaos.
- Arch-Enemy: Izumo-no-Okuni has been hunting him her whole life, and keeps doing so as a Heroic Spirit.
- Big Bad Duumvirate: He and Takasugi Shinsaku are working together, but both of them have their own goals and they try stab each other in the back a number of times during the event's climax.
- Body Surf: It doesn't stick with one host for any time longer than needed. If the host has done everything that it can do or it runs into trouble, it will just jump into someone else's body and spread more chaos with them.
- Demonic Possession: He operates by possessing person after person. During the event, he possesses Lancer Sakamoto, and he also briefly uses his powers on Tanaka Shinbei and Takechi.
- Deus Est Machina: He is forced into this trope when Takasugi reveals that the mechanical body he created for him is actually meant to trap him and use his power to recreate Japan.
- Hoist by His Own Petard:
- He chose to possess the guy with the anti-divine weapon. That's actively weakening him just by being near. This is another reason about why Rider Ryouma's Taking You with Me gamble works.
- As pointed out by Takasugi, while he is used to deceiving people he isn't used to being deceived.
- Loss of Inhibitions: Those possessed by it will have all their negative emotions surface so that they will try to act irrationally. For example, Ama-no-Sakagami jumped into Chacha's body in the beginning of the event to make her transform into the Avenger-class Yodo-dono.
- Malevolent Masked Men: The only feature it has in its otherwise shadow body is a reflective mask.
- More than Mind Control: He uses even the tiniest negative emotions as his means to possess people, and amplifies these emotions a LOT.
- Sealed Evil in a Can: He was sealed away by the village/cult that kidnapped Okuni, but one of the other girls succumbed to him and released him.
Sea Monster Crisis - Floating Island of the Innocents
Origin: Iraq (Mesopotamian Mythology)
An old god who hailed from Sumerian mythology, where he was known as the god of fertility and grain. That is, that is what he was originally known for, but over time the belief in him has drastically changed, first having him appear as a half-man half-fish god and later distorting him further until he was nothing more than a sea monster. While he denies his change, he knows that gods are made by the belief in them, and thus now wants to create a new circle of worship to revere him as the god he once was.
He is the main villain of the "Sea Monster Crisis" event.
- Clap Your Hands If You Believe: Dagon was originally an agricultural god worshiped by the Sumerians, but the popular misconception of him as a sea-god perpetuated by various sources has turned him into a humanoid fish-monster.
- The Dog Was the Mastermind: The elderly turtle who is the village elder of the Con in the turtle island? He was actually Dagon, growing the Con in the back of a giant Feng so that they can be fed to the water monsters to make them Dagon's worshippers.
- God Needs Prayer Badly: Dagon is an example of how the faith in gods can change them. Originally he was just a humble god of grain, but influences like the Hebrew Bible, murals that most likely depicted Kulullû and later works like The Shadow Over Innsmouth have changed him into a being known as nothing more than a malevolent sea creature. His plan in the event is to try to gain back his fame by creating a new cult to worship him as the god he deserves to be.
- Shut Up, Kirk!: When Ereshigal tries to give him an Alas, Poor Villain speech, he retorts by stating that she also has the chance of falling down the same hole he has been trapped in. When Ereshigal tries to counter his statement, Dagon decides to turn into mist in order to poison the world's waters like the supposed evil god he is. Ereshigal is shocked how her Talking the Monster to Death failed.
- Then Let Me Be Evil: After he's defeated, he decides to poison all the world's waters as if he can't regain his original status, he might as well embrace his status as an evil god in his final actions.
- Villainy-Free Villain: In contrast to Lostbelt Dioscuri (who really want to kill all humans) and Ashtart Origin (who wants to destroy the entire Servantverse), all that Dagon plans to do is form a cult to worship him by creating a Singularity on top of a giant Feng and filling it with myriad of water creatures. While the plan does involve devouring the Con, they are ultimately semi-sentient fungi growing out of the Feng. The first actually evil thing he does is try to flood the turtle island, which is only after Chaldea had already defeated all of his monsters.
Serial Genesis Days: Mississippi Mythicizers
Origin: North America (18th century)
A semi-mythical folk hero who acted as a boatman who ran keelboats across the Mississippi River.
- Breath Weapon: Can seemingly breathe fire in one of Super Bunyan's animations.
- Clipped-Wing Angel: He starts out the battle as a decently-strong Kali Sangha enemy. But after you break his bar, he reverts down to a really weak Kali enemy, meaning that the fight is more or less over at that point.
- Dude, Where's My Respect?: He hates the fact that Super Bunyan, some nobody who never existed in the first place, especially in this form, is going to get turned into reality while he is just stuck into her Spirit Origin, leading to him hijacking her Spirit Origin to get the recognition he thinks he deserves.
- Never Smile at a Crocodile: The descriptions of him being a "half-horse, half-alligator" seemed to have caught up to him in his current form, as he now manifests as a baby gator.
- Normal Fish in a Tiny Pond: Inverted. He is a semi-legendary American figure who you need to face with less-recognized Heroic Spirits, so he seemed to be one in the advantage. But as it turns out, the "king of the keelboats" does not fare well in an era where even steamboats have fallen out of favor.
- Post-Final Boss: At the time he finally decides to intervene, Anning had been defeated and Super Bunyan's guilt of what she had gone has been resolved, meaning that him deciding to intervene is just because he hates Paul Bunyan getting all of the spotlights.
- Toxic Friend Influence: Before his villain reveal, his main role in the story is advising Bunyan that leadership involves not taking criticism from others and that she should see herself as infallible.
- Combining Mecha: Evokes the image of one, with a Holy Grail acting as the torso and the Elisabeths acting as the ligaments.
- Fusion Dance: She's a combination between Elisabeth Báthory and her alternate variants. And apparently she could go even further if there were Elisabeths for the remaining Classes to become Ultimate Elisa XXX.
- Giant Space Flea from Nowhere: There is absolutely no explanation as to how or why she's the last thing you face in Fate/Freedom Order. She just is.
