* "Faker" for Hephaestion Mnemosyne, from her original class in ''LightNovel/LordElMelloiIICaseFiles''. In fact, she insists on the player calling her by that name.

** TheReveal in Lostbelt 2.7 officially gives him the title [[spoiler:[[Anime/GaoGaiGar The King of Braves]]]], not only because of [[Creator/NobuyukiHiyama sharing the same voice]], but [[spoiler:how he (temporarily) defeated ORT includes [[AllYourPowersCombined fusing with all his subjects]] and ending the fight with tearing out ORT's core, not unlike how the aforementioned bearer of the title defeats his foes]].

** TheReveal in Lostbelt 2.7 also gives him the title [[spoiler:[[Anime/GaoGaiGar The King of Braves]]]], not only because of [[Creator/NobuyukiHiyama sharing the same voice]], but [[spoiler:how he (temporarily) defeated ORT includes [[AllYourPowersCombined fusing with all his subjects]] and ending the fight with tearing out ORT's core, not unlike how the aforementioned bearer of the title defeats his foes]].

* "[[Franchise/MetalGear Big Boss]]" for William Tell due to having similar demeanor and design, most especially when he wears an eyepatch in his Third Ascension.

* Tiamat is often referred to as "Tiamomma", "Tiamom", or just "Mom" due to her status as [[MotherGoddess the Primordial Mother]] and [[MyBelovedSmother her overall demeanor]] towards the Master in both Mobile and Arcade.

** Tiamat is often referred to as "Tiamomma", "Tiamom", or just "Mom" due to her status as [[MotherGoddess the Primordial Mother]] and [[MyBelovedSmother her overall demeanor]] towards the Master in both Mobile and Arcade.

** Another nickname for him would be "[[LightNovel/TheHeroIsOverpoweredButOverlyCautious The Cautious Crypter]]", due to being ''dangerously'' savvy in his Lostbelt by ordering an ''entire fleet'' lead by both him and his [[TheDragon Servant Caenis]].

** Due to Babylonia having dedicated Anti-Ishtar measures (i.e. nets) and [[ButtMonkey her propensity for her antics to blow up in her face]] (see Babylonia and the Summer 2017 event), fans also often call her [[LightNovel/KonoSuba "Damegami" (Useless Goddess)]] as an InsultOfEndearment.

** Also [[GamerChick Gamer Inferno]], coming from her My Room lines and [[Creator/HisakoKanemoto the voice actor's previous role]] as [[LightNovel/Gamers2015 Karen Tendou]].

* Mandricardo is called "Ricardo" which is a shortcut of his name. He's also called [[LightNovel/MyYouthRomanticComedyIsWrongAsIExpected Hachiman]] because of similar character designs. Also "My Friend" or the {{Engrish}} version of "Mai Furendo" after interactions with him solely refer to him as such in Atlantis.

* Avicebro for Avicebron, since it's just as easy as removing one letter from his name, and [[spoiler:he's quite the bro in Lostbelt #1, as opposed to his eventual treachery in ''LightNovel/FateApocrypha''.]]
** Also [[Manga/{{Doraemon}} Avicemon]] due to [[ChessmasterSidekick his competence]] to solve almost every problem the protagonist faces in Lostbelt #1; or [[Anime/TheBigO Avicebron the Negotiator]] due to [[Creator/MitsuruMiyamoto his voice]], also leading to Adam being called [[Anime/TheBigO "Big O"]].[[labelnote:Note]]Which can lead to hilarious irony because the key to control Big O is getting the phrase: "Cast in the name of God. Ye not guilty.", but Avicebron [[TheAtoner clearly thinks he's guilty]] for [[spoiler:betraying Roche in ''LightNovel/FateApocrypha'']], like in [[https://www.pixiv.net/en/artworks/68208096 this piece of fanwork]][[/labelnote]]

* [[LightNovel/FateApocrypha As before]], "Jack the {{Stripper|iffic}}" for Jack the Ripper.

* Thanks to her being an EvilCounterpart to Altria Caster, Morgan has been referred to as Castoria Alter. She also gets called [[LightNovel/VioletEvergarden "Violet Sabergarden"]] because she shares [[Creator/YuiIshikawa a voice actress]] with the eponymous character, and they are both Saberfaces.

** And now they're the [[LightNovel/HaruhiSuzumiya "Endless Eight"]] thanks to Koyanskaya and Oberon joining the mix.

* [[GagBoobs Mashumallow]] for Shielder, based on the Japanese pronunciation of her name combined with marshmallow and her chest. It's acknowledged by Scathach in her trial quest, and Blackbeard calls her this a few times.

* Altria's Lancer version is called CCO (read as "Shishi-O" for Lion King in Japanese), Lanceria or Lancuria. Her Lancer Alter version? Chichi-ue (a Japanese synonym for dad and breasts) or Lalter, in keeping with the Alter-naming convention. Both Lancer Altrias are also called [[GagBoobs Tit]]uria (Alter) or [[GratuitousJapanese Oppai]]toria (Alter) respectively, due to Rhongomyniad [[FanservicePack giving them a visible upgrade]].

* Boudica is either [[GagBoobs Boobica]] or [[MaleGaze Bootyca]].

** There's also the nickname "Raicow" due to her [[GagBoobs disproportionately-large bust]].[[labelnote:note]]Which is also a nod to her alternate persona Ushi Gozen, whose name can be translated as "Cow Lady".[[/labelnote]]

* Dadcelot for Lancelot due to acting like a doting (and sometimes, in fanart, [[OverprotectiveDad overprotective]]) father to [[spoiler: Mash]]. He is also called Saberlot to differentiate him from his Berserker self.

* Fairy Knight Gawain is often called "THICC Gawain", what with her large, muscular stature, and her curvaceous figure. Some also call her "Gorillatina", as both a reference to their Noble Phantasms, and Gawain's previous "Gorilla" nickname. Others also call her "Big Doge Waifu" due to her true identity as [[spoiler:[[HellHound the Black Dog Barghest]].]] In the Japanese fandom, she's known as Gawako (or [[spoiler:Bageko]], her InSeriesNickname from Caster Altria).

* Ixquic gets referred to as [[spoiler: Dino Arcueid]] because she's Lostbelt 7's version of [[spoiler: Archetype Earth.]] Similarly, Tepeu is [[spoiler: Dino Shiki.]]

* Ixquic gets refered to as [[spoiler: Dino Arcueid]] because she's Lostbelt 7's version of [[spoiler: Archetype Earth.]] Similarly, Tepeu is [[spoiler: Dino Shiki.]]

** And before her true identity was revealed, she was also referred to as "Tittyba" or "THICC Caster" (like Scheherazade) during her tenure as [[JustForPun Tit]]uba because of her, uh, [[BuxomIsBetter large assets]].

* Demeter is sometimes referred to as "Melon Bread Goddess", due to her color scheme resembling a melon, and the orb that she holds in her hand somewhat resembling a melon bread. And she has... [[BuxomIsBetter nice melon breads.]] Yes, indeed.
