History FanficRecs / KingdomHeartsCrossovers

* Comments: In spite of being written in a script format, some spelling and slight grammar errors, and a few little plot holes, this fanfiction crossover is intriguing to read. The narrative contains wonderful adventures, good actions/fight scenes, charming chemistry or relationships between the main protagonists and the characters, and excellent drama. What also makes this fanfic crossover feel so engaging to read through is that it stays true to the lores of two different worlds, balances them well as the story progresses, and enhances upon them for a unique story-telling. It even explores some interesting subjects that haven’t been touched on between different universes and ties them into the plot.

* Comments: One of the rare few times that Mass Effect gets crossed over with a fantasy setting, and it's glorious. It starts very much like a typical "X character ends up in another world" setup, with Roxas mysteriously finding himself in the Citadel. However, over the course of the events the ''Kingdom Hearts'' and ''Mass Effect'' universes start blending more and more, and the cast of characters gets increasingly diverse, slowly but surely diverging from canon. It starts with the Heartless appearing in the Citadel and goes from there. It also introduces several new Disney worlds - or references - that were not included in the original games, such as ''WesternAnimation/TheIncredibles'', ''WesternAnimation/TreasurePlanet'', ''WesternAnimation/LiloAndStitch'', and more.

* Comment: Very engaging. Sora and Kairi were tasked by "Master Yen Sid" to venture into a new world, only to find that this new world is barren of Hearts except for Issac.

''[[https://www.fanfiction.net/s/13972156/1/ Kingdom Hearts: The Master Who Fell Through the World]]'' by [https://www.fanfiction.net/u/765650/ Lord Maximus]

* Comments: In spite of being written in a script format, some spelling and slight grammar errors, and a few little plot holes, this fanfiction crossover is intriguing to read. The narrative contains wonderful adventures, good actions/fight scenes, charming chemistry or relationships between the main protagonists and the characters, and excellent drama. What also makes this fanfic crossover feel so engaging to read through is that it stays true to the lores of two different worlds, balances them well as the story progresses, and enhances upon them for a unique story-telling. It even explores some interesting subjects that haven’t been touched on between different universes and ties into the plot.

* Synopsis: After what Sora considers to be the most challenging fight of his life, he expected to be teleported back to the Final World. What he didn't expect was to wake up in a world filled with Gods and a Dungeon so deep that no one knows how far it goes. Finding a way back home isn't going to be easy, but at the very least, he has a hearth to fall back on; Basically, the story is about what would happen if Sora after fighting Yozora ends up teleported to Orario (DanMachi) and meets a certain rookie adventurer and a certain household goddess.

* Comments: Although the fic's focus lies primarily with a WesternAnimation/StevenUniverse character, it still has accurate characterization of the main trio and excellent, if somewhat verbose, writing. The author has also written it with the intent of being understandable by people not fans of WesternAnimation/StevenUniverse, so you don't need to worry about proper franchise knowledge.

* Recomended by: thedarkone1995

* Synopsis: You all know the events that lead up to Sora's disappearance from his and his intense battle with Yozora. But what if instead of ending up in the city Quadratum, he ended up in the fabled Clock Tower, meeting the infamous Wizard Marshal. Guided by him, Sora ends up in a world where humanity is on the brink of destruction and must save it with Chaldea's Final Master.

* Status: ongoing

* Comments: Though still quite unifinished, it already features characters from ''VideoGame/KidIcarus, Franchise/{{Pokemon}},'' and ''Franchise/FireEmblem,'' with more to come. It is extremely well written and definitely worth reading and following.

* Comments: A thoughouly entertaining series about a group of villains who come together around a common goal of conquest and destruction, [[ALighterShadeOfBlack fighting off even bigger threats]] [[EvilVsEvil and other rivals]] in their quest for power and becoming a FamilyOfChoice along the way. The first fic was completed and the second one started before Kingdom Hearts III was released, and while it does incorporate later reveals from the games into it's storyline, it does remain it's own story without trying to fit itself into canon.
