Both Kamen Rider and Chaldea Organization will have to team up to save every timeline and the parallel world, including theirs to persevere their future from an unknown extinction. Basically, my take on FGO x KR crossover story. Small risks of OOC.

Yet again Zelretch has sent our little redhead Gudako Emiya into another world this in the world of Thedas. Now resurrected in an exact copy of the Harem King himself he must face the ever-looming threat of the Darkspawn as the Blight fast approaches.

Due to an experiment gone wrong, Tony, Thor and Hulk are now in Chaldea. A place which deals with threats that could wipe out human history, the Chaldea is currently having a problem with there other 47 masters injured, they are on short of man or servant power. Show what will happpen if they came cross the avengers, who has their own fair share of world ending threats.

When Shirou Emiya died, he expected to reincarnate or transcend to the Throne of Heroes for his deeds as a Chaldean Master. Never did he expect to end up in another world still in the Age of Gods or become a God. This is the story of Shirou Emiya, a new God of Heroes. His time on Genkai. How will Bell Cranel, his friends and harem be affected by Shirou? [AU Warning]

Death and corruption. A rotting Empire, and a man who would sit at the heart of a revolution. In a dark world of constant death and deceit, what place will a man whose only wish was to save others be able to carve out for himself?

When a 12 year old Shirou finds himself in another world with no explanation how he got there, he knew he was in trouble. The fact that he woke up in a cage, a Slave Crest on his chest and odd new additions to his body underscored this fact. Naofumi, the disgraced Shield Hero, did not care about any of that. He just needed these two raccoon demi-humans to be able to fight. AU.

Hardy was selecting a world for the Gate to open to Falmart, the garden of the gods, but the Earth she selected was the worst one she chose. It was an Earth where Divine Spirits failed to manifest and walk the Earth due to a lack of a certain something that Falmart was blessed with. The last thing Hardy was expecting was to unleash a plague of gods onto Falmart.

Reborn was confused. Like really confused. But he did understand that his assignment had gotten a lot harder.(Fem! Tsuna)

When a God from another dimension request the Kaleidoscope, Zelrech, to summon a few certain people to watch the Fate Series, in hopes to give them ideas and inspiration for the future. RWBY is owned by Rooster Teeth and the Fate Series is owned by Type-Moon

Gamer!Jeanne Alter, First world- Overlord. A bit of a sandbox fic and my first in the Gamer style so don't expect perfection. That said though, do enjoy.

Una joven, con un pasado oscuro y horrible, salvada y entrenada por el Caleidoscopio, llega a Chaldea en una misión de su maestro, pero se vuelve una inesperadamente una batalla por el orden humano. Ahora, ella no solo tendrá que pelear al lado de aquellos que son la esperanza de la humanidad, sino también a abrir su cerrado corazón. (Mithraxharem)

An collection of fragments gathered together; adventures and accidents that might be, could be, or have yet to be. Servants that have yet to be born or will be born, destined for great things. Shards lost somewhere in the abyss between the Throne, the Moon, or the Grail. Yet they were Unlikely indeed, if only for their infamy. These are their stories. Narutoxharem? Vote via review!

Shirou Emiya was transported to another world as a sick prank by the Wizard Marshall himself. Now he have to be with new ally against the forces of evil with 'The Girl Who Lived

After failing to bring Sasuke back to Konoha, Naruko is banished from her home. She travels to the ruins of Uzushiogakure where she discovers a ancient secret long forgotten by her clan. With it comes new powers along with the revival of her clans home.

It is not everyday that you sleep and wake up in another world with the purpose of saving humanity. That's what he found myself in when he woke up in the world of RWBY of all things. Even more surprising is that whoever chose him had left him as the Knight of Rebellion. So prepare yourself world! The Knight of Rebellion marches onwards to save the world! SI, Self-insert as Mordred.

A rewrite of two former fate/kingdom hearts crossovers I have done before. Come! Read a new story of Ventus and his adventures with Heroic Spirits, and how he became one himself! (Also, the cover art is something I did myself.)

Por aburrimiento de Kaledoscopio, mira Remnat, sus heroes y historia y dijo, porque no divertirme un poco, Jaune tendra que salvar el mundo, pero no esta solo, su padrino que tiene muchos secretos del mundo le ayudara, mas de lo que espera, amor, traicion, superación personal mucho mas en este fic. (Lemon en algun momento), acepto consejos y revisiones. (imagen alex-kellar)

Betrayed by my people, I have been granted vengeance. My master has granted us the power to reshape our empire into our own image. The feeble attempt from the Counter Force has failed and now serves the Eternal Empire. Oh Chaldeans, let us see who will be victorious in our Grandest Holy Grail War. Fate/Grand Order: New Order- The Everlasting War: Miraculous.

Zelretch flings Shirou off into another world and tells him to await rescue via Rin. Easy task right? Wait a second what's with all these phantasmal beasts and why do they look like people?

Fate stay/night x Fate Grand Order Y/n a normal high school girl died in a car accident. When she opened her eyes she was a kid again, but that's not all she looks awfully familiar. And was more shocking is that she is in her favorite Anime Fate stay/night. And she became Shirou Emiya's Little Sister. The Fate stay/night and Fate/Grand Order are owned by Type-Moon, and ufotable.

There are many facets of the Kaleidoscope. Lord Zeltretch is curious as to why one seems to lack Magecraft, and so sets a Kaleidostick to the task. For good or for ill, that kaleidostick has chosen Taylor Hebert as her master. Rated for language

When Sougo reset everything at the end of Zi-O things didn't go quite as planned. A new world was created. But rejoice, for the King of Time and Space shall stand against the Incineration of Mankind, leading beings of myths and legend to correct history.

When all else fails blame Zelretch right? No, this time it's just a wayward Tribrid who summoned a certain Sword Magus instead of her parents. The one time Zelretch swears not to watch, he should have. For the adventure begins anew with a familiar summoning ritual. (This is an AU where there was more to Shirou than anyone thought.)

The world had abandoned her. Humanity had betrayed her. The Gods were laughing from their high seats. She had not been broken. Not yet. As long as her hero stood by her side.

Fem!Shirou and Arthur found themselves in a world eerily similar, but at the same time different, to the fictional world Pokemon. Shirou finds herself transformed into a female Pokeslave, a Pokegirl. It is up to Shirou and Arthur to find clues to reversing Shirou's transformation before either Shirou or Arthur succumbs about their new statuses. Fate Route AU.
