* In the Website/SpaceBattlesDotCom Creative Forums, ''Zero no Tsukaima'' story threads are spawned on a regular basis as the ''Zero no Tsukaima'' Story Ideas and Snippets threads are rapidly filled up and new threads are created regularly. Threads contain brief snippets and ideas on ''Zero no Tsukaima'' fanfiction and story snippets are indexed in the [[ The Index]]. The [=SpaceBattles=] Creative forums also has a ''Zero no Tsukaima'' [[ Back to the Basics]](link is current at time of writing) Thread to help clarify any misconceptions about the ''Zero no Tsukaima'' canon(Note:by 'any' I mean A LOT). Contains the largest collection of summons, reverse summons, bad ends and any other imaginable scenario that has zero chance of being written outside of [=SpaceBattles=]. May be hard to navigate due to sheer number of threads ([[ #45]]) at the time of writing. A listing of longer Spacebattles stories may also be found ([[ here ]]).

''[[ Drifter Series: Revolution and Freedom]]'' by General RTS
* Recommended by: [=TheRealLee=]
* Status: Complete
* Synopsis: Japanese-American and US army ranger Alexander Tsougi always considered himself to be a normal military grunt. That is until he teleports through a magic portal into the world of Zero no tsukaima. WARNING: the following story gets really epic by chapter 3.
** [=TotalAbsolutism=]: This story has quite a few problems. The Nobles are constantly holding the idiot ball and seem totally unable to adapt to fairly basic military tactics. They also seem to constantly forget that they have a little thing called 'Magic' that could be used to render a fair number of those basic tactics totally obsolete. They will frequently underestimate the enemy even when doing so has proven disastrous in the past. Finally, the Author seems to go out of their way to make the Feudal system that exists in Halkegenia look a lot worse than it really would be when that's quite unnecessary; there's plenty of real issues with such a thing without having to invent extras. If you can enjoy it in spite of this then more power to you, but these problems really drew me out of it.

* Synopsis: UsefulNotes/NapoleonBonaparte, just after his defeat, is summoned as Louise's familiar. Things get...interesting.

''[[ Enslaved]]'' by [=Shadenight123=]
* Recommended by: [=Twinkieman92=], @/TheGiantRock, [=NeonFraction=]
* Status: Dead
* Synopsis: Hiraga Saito is a fleshed out character. Louise Françoise isn't happily whipping people. The summoning ritual does ExactlyWhatItSaysOnTheTin, summoning creature to be branded and then enslaved by the influence of the mark. There is nothing happy about it. ''Familiar of Zero'', with 'For The Laughs' removed. How bleak are things, really?
* Comments:
** [=NeonFraction=]: While 'fleshed out' may be an exaggerated description of the changes to Saito's character, he does take a definite level in badass. For anyone who couldn't get over how horribly abusive Louise was or how unfair the series was to Saito, seeing him make his way independently is a fantastic change. While I wouldn't say it's incredibly well written, it's a story intended to satisfy more than entertain. And satisfy it does. For all its flaws, you'll be cheering for Saito every step of the way.

''[[ Familiar of the Fairy]]'' by Juubi-K
* Recommended by: Overlord Zaru
* Status: Ongoing
* Synopsis: Reconquista is defeated, but dark forces and darker ambitions threaten to plunge Halkeginia into war. Into this morass is plunged a wanderer from a distant land, summoned as a familiar by a certain young half-Elf.
* Comments:
** Overlord Zaru: Relatively young and new, but shows promise thus far. A new faction comes into play and will be interesting to follow through. And it seems that Tiffa will get some spotlight alongside our heroes Saito and Louise.

* Status: Dead
* Synopsis: The US Government sends a Navy SEAL into a newly discovered world to recover lost equipment and weapons, and to explore this new world. This is going to be one of the most interesting missions for Commander Riptide, Sniper for SEAL Team 10.
* Commetns:
** eduardogranja: Must say it feels good to see the reaction of Halkegenians to a true military force from Earth, and that was enough to get me hooked in the story. As of now, the story is on the higher end of the epic scale.

''[[ Soldier of Zero]]'' by Ashen Author
* Recommended by: [=AshDevil=], @/AckSed, @/UncloudedTJ
* Status: Dead
* Synopsis: Louise still summons Saito, but the world he comes from is different. He can't ''cast'' magic, but he knows enough about it to give Louise a little help, and he has some other skills too. Most importantly, it's primarily Saito as a GuileHero instead of relying on brute force. Mind games are to be expected.

''Fanfic/TheSteepPathAhead'' by [=Shadenight123=]
* Recommended by: Leid
* Status: Dead
* Synopsis: From the same author as Souls Art Online and Enslaved, The Steep Path Ahead is set in an AU of The Familiar of Zero where Louise is kidnapped by an elf as a child only for the ones who hired him to die before paying him, so he dropped her off in an orphanage. Several years later, Luise fails her exam to get into the Academy and summons Saito in order to prove that she isn't a failure.
%% Please note that Luise is the new name as it's the Germanic version of her name and not a typo of Louise.

* Synopsis: Saito Hiraga refuses to let people walk all over him. He had plans, he was going to join ROTC, he was going to outrank his brother and sister, he was going to help people. He was smart enough for it, he was strong enough for it, he was determined to be at the top of his future class. But one summoning spell changes everything, and he loses control of his future.

''[[ A-Null-Content]]'' by [=ThatDarnDrilltank=]
* Recommended by: Aroxys
* Status: Hiatus
* Synopsis: Most tales of Halkeginia start the same way, with Louise calling someone to her side from beyond the veil, and little outright changing beyond that. This time, it seems as though something's changed much further back than that event, causing staggering and unforeseen changes. Something made the trip from Earth to Halk under its own power, and it has its own ideas of what to do...

''[[ Maid of Honour]]'' by escalus01
* Recommended by: fruitstripegum
* Status: Ongoing
* Synopsis: A disastrous incident a week before the ceremony causes some changes in Louise's life that result in her summoning a different familiar, one ill-prepared for the responsibilities about to be thrust upon her.

''[[ Loopholes]]'' by DschingisKhan
* Recommended by: fruitstripegum, @/UncloudedTJ
* Status: Ongoing
* Synopsis: Louise didn't summon a dragon or a loser from another world. No, she summoned a girl from across the yard. How humiliating! But why is Tabitha agreeing to be her familiar? And how many teenage girls does it take to destabilise a geopolitical region anyway?


Given the nature of the series' setup, a common crossover theme is to replace Saito with a character from another series in question.


''[[ A Certain Scientific Familiar]]'' by Ketchum Kid
* Recommended by: ultimomant
* Status: Dormant
* Synopsis: Louise wanted a beautiful and wise familiar. What she got was a walking power plant with no patience for disrespect to anyone. In a world where nobles and magic rule and espers and science are non-existent, can the Zero of Tristain cope with having a familiar that is the Ace of Tokiwadai?
* Comments: What really makes this an excellent crossover is that not only is Mikoto doing her best to change and improve this world she found herself in, the fic occasionally switches back to Academy City and shows Touma and Mikoto's friends doing their best to figure out what happened to her and bring her back.

One wish, to finally live free. One wish, to finally meet again after so long apart. One wish, to be forgiven for the sin of betrayal. One wish, and it changes the world.

* Synopsis: The Gandalfr is the Shield of God, meant to protect their summoner from harm. Through faith and blade, here was a man that protected the weak from all that would do them harm, and his life ended with no regrets.

''[[ Echoes of the Void]]'' by [=AlfheimWanderer=]
* Recommended by: @/{{Rivenscryr}}, @/{{Jiven}}, nitewind, expertus
* Status: Alive as of August 2, 2017
* Synopsis: In a society where magic is the proof of nobility, Louise Françoise Le Blanc de La Vallière, has never managed to cast a single spell properly. Scorned by her classmates as "the Zero" for her utter incompetence, the Familiar Summoning Ritual is her last chance to prove herself worthy of a title. But imagine her surprise when she summons someone as inextricably linked to the void as she, a young girl with a need to prove herself nearly as large as hers.

''[[ Recollections of Pain]]'' by [=AlfheimWanderer=]
* Recommended by: @/{{Jiven}}, @/{{Rivenscryr}}, nitewind
* Status: Dead
* Synopsis: In a world where magic is the proof of nobility, Louise Françoise Le Blanc de La Vallière is an outcast, bearing the stigma of failure, as she has never been able to use the simplest of spells. Scorned by society as "the Zero," a woeful all-but-commoner with pretensions to the high nobility, the Springtime Summoning Rite is her last chance to prove otherwise. To everyone's surprise, she summons something - but when millennia long traditions hold that the summoned being reflects the caster's ability as a mage, what does it mean that her familiar is blind?


''[[ The Darkest Void]]'' by Lord Mendasuit (AKA Tropers/IAmNotCreativeEnough)
* Recommended by: tsukinoimai
* Status: Dead
* Synopsis: Darkness brings more darkness. She was a failure of a mage, incapable of casting even the simplest spells. So of course, she had to go ahead and summon the single most talented mage of his generation as a familiar.

''[[ Puppets of Zero]]'' by sagitarius
* Recommended by: Averruncus of the shadows
* Status: Dead
* Synopsis: A different take on the usual 'replace Saito with X' stories that dominate the [[LightNovel/TheFamiliarOfZero ZnT]] crossover archives. Rather than summon a single familiar, Louise summons [[spoiler: the four Averrunci, (starting from Fate to Sextum)]].

''[[ A Summon Goes Wrong: Mahou Gakusei Louise]]'' by [=Nervaqus987=]

''[[ The Floating Castle]]'' by Racke
* Recommended by: [=TheSinful=]
* Status: Complete
* Synopsis: Her summon didn't appear, and nobody saw fit to question it. It'd been a cloudy day, and why should they've been looking upwards anyway?
* Comments: Unlike almost every other story where Louise summons a different familiar and they become all kinds of awesome together, here Louise summons the entirety of Aincrad and never actually learns of the fact. Short but well written, the story explores the very real problems that come from the game suddenly being reality and a new military power appearing in Halkagenia.

''Fanfic/HalkegeniaOnline'' by Triggerhappy
* Recommended by: [=HK87=], @/{{Savoie}}, Zarclonia, nitewind, Sinclair, @/{{Mt}}, @/AckSed, aightaight, @/{{Robinton}}
* Status: Complete
* Synopsis: Louise got her wish to summon the most impressive familiar in her class when she ripped the entire Alfheim setting out of cyberspace and dumped it over Tristain. There's a giant tree looming over the academy, 61,000 "elves" who don't know why they're suddenly able to feel pain, monsters running amok in the countryside, and one particular black swordsman with an awful sense of deja vu. But what's become of Asuna, and what will the local schemers make of these new arrivals?

* Synopsis: Louise...summoned something different. An Acolyte of Warcraft Three, the most basic and seemingly useless unit in the history of the Scourge. However, when you look at it in a different way, the Acolyte can create enormous constructions out of sheer nothingness provided there are resources. The most basic unit, becomes the most important.

* Synopsis: Louise summons Zero from ''VideoGame/MegaManX'' with interesting results as Zero comes of a high-tech society to Louise's Late Medieval Europe. Oh, and if women are booty then you might as well start calling Zero His Royal Badassery King Emperor Knight Captain Duke Jesus Double Cap'n Zero. Because he's so powerful he can turn Albion into a crater. Floating and or otherwise. The author really has a knack for writing overpowered characters like Zero.

''[[ Dwarf of Bronze]]'' by [=TotalAbsolutism=] ([[ FFN]], [[ Spacebattles Thread]], [[ Sufficient Velocity Thread]])

* Recommended by: [=MistahD=]
* Status: Ongoing
* Synopsis: Because of a change to the magic rules of the setting Familiar Summonings are performed in pairs to enhance the effect. Louise is paired up with Guiche de Gramont; and this causes both of them to summon unique familiars.
* Comment: This one is a bit weird; it's a crossover with an original setting and mostly follows Guiche (as weird a choice as any there could be). But it's decently written, pretty unique, and isn't afraid to totally derail canon. Also commendable for one of the best uses of Mott that this troper has ever seen.

* Synopsis: ''"I beg of you… My slave who lives somewhere in the universe! Oh sacred, beautiful and strong familiar spirit! I desire and here I plead from my heart! Answer to my guidance!"'' For such powerful magic words they are quite vague are they not? The universe has long since been proven to be far more massive than can be measured and the reflections even more infinite. Beautiful and strong can be defined in numerous ways and differ by one's own views of strength and beauty. However, a plea that comes straight from the heart fueled by a desire created from years of emotional torment by one's peers? That is a voice heard by any who are willing to listen.

* Synopsis: In Tristian's Magic Academy, Louise asked the void for the greatest familiar in all the land. In the depths of Waterfall, Undyne wanted to escape the Underground. What happens when these magical worlds collide? Guess this is a case of being careful what you wish for.
* Comments: Many have said that a part of what makes [=FoZ=] fanfics BetterThanCanon is that Louise summons a character that does not put up with her attitude. This is one such story. Undyne is just fantastic: she's not afraid to speak her mind, especially when she sees someone being abused while also being amazed at the surface world and being a huge dork who accidentally breaks almost everything she touches and carries Sylphid around to show off her strength. This story is definitely worth a read.

Mysterious figments that only she can see above everyone's head and incomprehensible message popping up in front of her. Is she just going crazy or is this the mysterious will of the founder? And what the heck is "The Gamer"?
* Comments: This is probably both the most original [[LightNovel/TheFamiliarOfZero ZnT]] crossover and [[Webcomic/TheGamer The Gamer]] crossover at the same time. Instead of an overpowered familiar to solve all her problems, Louise instead gains an ability that can master any skill and become insanely powerful extremely quickly, but because she's from a [[MedievalEuropeanFantasy Medieval Fantasy World]] and doesn't even know what the game in gamer is referring to and thus lacks the knowledge that other crossover have used to make The Gamer overpowered at the start of the story.

''FanFic/StormsOverhead'' by Lione 'Tabuukilla' Fortuna
* Recommended by: [=MagusPandora=]
* Crossover with: ''VideoGame/InFAMOUS''
* Status: Complete
* Synopsis: He was known as the Wrath of Odin, Zeus' Rage... and monster, But yet, all he desired was to redeem himself in the eyes of the world that had seen him as nothing but a monster. Defending several Conduit children, he holds up against the militia in a final act of redemption. But just as death comes for him... a pink haired mage calls for a familiar.
** [=TotalAbsolutism=]: This story starts off... poorly. It adheres to the common yet inaccurate fanon idea of the Familiar Runes being mind control devices of some sort which isn't even remotely accurate; their only displayed mental interference function is to suppress homesickness. Louise also reacts very poorly to her familiar even though he's not being a pervert like Saito. But for all that I felt it improved enough to be worth carrying on with and I enjoyed it in spite of a poor initial impression.

''[[ Through the World Door]]'' by Leo Septem
* Recommended by: @/ShadowArisato
* Crossover with: ''LightNovel/HighSchoolDXD''
* Status: Dead
* Synopsis: Saito Hiraga, the Gandalfr, has finally returned to his homeworld of Earth after a year of trials, suffering, and enslavement in the land of magic and monsters, Halkeginia. But even on Earth, he is not safe from the supernatural. And even on Earth, he may just find himself bound by the chains of servitude once more...
* Comments: This is not your average "Louise-has-a-familiar-that's-not-Saito" fanfic crossover. It's one where Saito returns to Earth and with his Gandalfr abilities intact. However... Well, just read and find out what happens. It looks promising with its very detailed and long chapters.

* Crossover with: ''VideoGame/{{Prototype}}''

* Synopsis: Louise summons [[spoiler:the Blacklight-virus entity that calls itself]] Alex Mercer. That alone ''would'' be enough to describe the story that ensues, except that the history of Halkeginia is a ''little'' different from in canon...

''[[ Zero's Bullet]]'' by The Woodsman
* Recommended by: [=TheSinful=]
* Crossover with: ''Manga/{{Hellsing}}''
* Status: Death by AuthorExistenceFailure
* Synopsis: The Huntress has escaped her Zamiel. Now she finds herself trapped on an unfamiliar world where nothing makes sense. What's more, she has become the contracted familiar to a no talent young mage known as the Zero. This is a story of blood, gore, madness and carnage. This is the story of Zero's Bullet.
* Comments: Louise summons Rip Van Winkle as her familiar, who manages to stay evil while also being humanized. The story switches from light and amusing (Rip protesting she didn't steal a parasol but found it) to dark and horrific (Rip ''eating'' Siesta). Sadly, with the author dead there's no chance of it being completed.

''[[ Zero Interface]]'' by Golden Arms
* Recommended by: [=TheSinful=]
* Crossover with: ''Manga/RanmaOneHalf''
* Status: Dead
* Synopsis: Ranma taunts his father on his first day of school at Furinkan, only to end up falling through a portal that leads him to Halkeginia. However, just because Ranma is made Louise's familiar doesn't mean he's taking it lying down.
* Comments: Imagine a story that combines all the zany harem antics of Manga/RanmaOneHalf with the zany harem antics of ''LightNovel/TheFamiliarOfZero''; that's Zero Interface. While the story has plenty of dramatic and awesome moments, the real draw is the comedy. Especially when Ranma's curse changes from turning into a female version of himself to [[spoiler:turning into whichever woman he kissed last]] and Louise getting an empathetic link with Ranma. So if say, Ranma has lustful thoughts towards someone, so does Louise.
