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.
Synopsis: Shirou Emiya (now in his mid-twenties) has dealt with human summoning, magical battles, and saving the world. Now he is brought into a world where magic equates to nobility. The Zero has just summoned a Hero. Has its own Trope Page.
Synopsis: After "succesfully" completing the Springtime Familiar ritual, Louise finds out that she is now the master of a certain white-haired homunculus. Follows the Unlimited Blade Works storyline.
Note: Also co-written/edited by AlfheimWanderer, so quality is just about guaranteed.
Synopsis: The Spring-Time Familiar Summoning Ritual summons the being most suitable for the mage. A soul of fire summons forth a soul of fire. The right spark can cause anything to burn. Fate/Zero Rider
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.
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?
Synopsis: On one end, a young mage who begged fate for something that would validate her reason for being. At the other, a young man who sought the desolation of his existence. Where they meet, is the terror that would shake the very foundations of magic.
Synopsis: Louise summons 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...
Synopsis: Louise summons Zero from Mega Man X 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 nack for writing overpowered characters like Zero.
Synopsis: Instead of going the same route as every single ZnT fic ever and having her summon yet another character from across the multiverse, Earthscorpion has her attempt the Familiar summoning ... and fail. Not just fail, but fail so badly a representative of Malfeas shows up to offer her a much more excitingalternative ...
Synopsis: A different take on the usual 'replace Saito with X' stories that dominate the ZnT crossover archives. Rather than summon a single familiar, Louise summons the four Averrunci, (starting from Fate to Sextum).
Synopsis: A completely new twist on the "Louise summons X instead of Saito" plot occurs when Louise summons Evangeline as her familiar only to be caught up in the snap-back on the Infernus Scholasticus. Look out Mahora, class 2-A has a new student!
Synopsis: Familiar spirits are the mark of those born with magic, their proof of nobility. To partake in their summoning, the most sacred act of all. Come, oh beautiful, sacred, strong familiar spirit, and grant us our heart's desire...
Synopsis: Louise summons a Necron Lord known as The Herald of the Storm who was fresh from a defeat. Herald immediatly assumes that (partly because of the magical contract making him loyal to her) Louise is a new, young C'tan. Hilarity and the occasional Curb-Stomp Battle ensues.
Synopsis: Team Rocket never expected to find themselves with a new Boss, especially the young untalented Louise the Zero. With no twerps and Pikachu to chase after, Team Rocket decides to serve their new Boss with full gusto, and show the land of Halkeginia she's no Zero. Whether Louise likes it or not.
Synopsis: Louise summons Kyuubey. A subsequent chance encounter with a Romalian Inquisitor sends things Off the Rails fast, though not in the way you'd expect.
