* Recommended by: Tropers/DarthTaco
* Crossover with: Various Creator/{{Nintendo}} games
* Status: Incomplete
* Synopsis: The borders between worlds have become blurred as a [[Franchise/KingdomHearts particular un-named franchise]] has grown overly complicated. Now it's bleeding into other realms, leaving [[VideoGame/KidIcarus Pit]] and [[MassiveMultiplayerCrossover the lost characters of Nintendo]] to deal with the increasing problem of the Heartless. But will finding a Keyblade really solve matters?
* Comments: Though still quite unfinished, 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.

''Fanfic/{{Starchaser}}'' by [[http://archiveofourown.org/users/TheDoomkitten The Doomkitten]]
* Recommended by: geekyasari
* Crossover with: ''WesternAnimation/StevenUniverse''
* Vanished from the internet. Please post a link if found.
* Synopsis: Connie Maheswaran: heroine, nerd, jam bud (formerly), knight, part of an experience, and occasionally a scared little girl. When everything she's ever known is ripped away from her one fateful night, Connie finds herself on an isolated island chain, protected from the encroaching darkness by some primordial magic. There, she must contend with the ashes of her past, prophetic dreams, her own insecurities, and a trio of kids determined to drag her out of the dumps by force if necessary.
* Comments: Although the fic's focus lies primarily with a WesternAnimation/StevenUniverse character, it still has the 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.
* Status Update: unfortunately this story appears to have died because I am unable to find it anywhere, even on The Doomkitten's Website/ArchiveOfOurOwn page.

* Recommended by Neo Shiraku, @/{{Robinton}}
* ''Status'': Complete; Sequel Dormant (as of Feb 2021)
* Crossover with: ''Manga/{{Naruto}}'', ''Anime/PuellaMagiMadokaMagica'', and ''Franchise/{{Digimon}}'' so far
* ''Synopsis'': A poster on ''Website/SpaceBattlesDotCom'' finds themselves transposed into the body of a [[TheHeartless Shadow]], and must survive long enough to return home.
** Robinton: To quote a few of the best lines from memory, "When the [[XanatosSpeedChess in-universe characters have reacted]], and [[GambitPileup launched plans of their own]], and the timeline's [[ButterflyEffect gone topsy-turvy]] to the point that even the SI doesn't know what's going on - that's when you know you're doing them justice." "Though the connection was brief, two Hearts beat with renewed Hope." "[[OneHitKill Quo Vadis]]. [[EleventhHourSuperpower And the skies burned crimson]]." "Memories cannot be truly Erased. Not so easily." "Trollbito." "If you see Drich, listen! Follow any orders Drich gives, unless specifically directed otherwise. If Drich is here, either Drich ate the Juubi, or the Juubi is free; either way, you'd better darn well listen." "I am [[DarkIsNotEvil The Dark Partition]]." I'd very highly recommend. Some sections drag on a bit, but overall one of the best fanfics in existence. If Drich wanted to go into writing, I'd follow.

* ''Comments'': A magnificent work thus far, adopted from fandombard12, lyokoMARVELanime has recrafted this crossover to encompass the events of ''Kingdom Hearts III'' except when [[spoiler: Xehanort struck Kairi down, Sora WASN'T able to bring her back.]] As a result, Sora has lapsed into a [[HeroicBsod Heroic BSoD]], and has been training every single spare moment he has, from dawn to dusk, until Riku sends word that Yen Sid, who happens to be friends with Ozpin, who later turns out to be a ShipperOnDeck for Roseheart aka Ruby x Sora, wishes to see him. Turns out Kairi's NotQuiteDead, thanks to a spell the Master of Masters had placed on No Name, and thus Sora, Roxas, Lea, and Ventus journey to Remnant and become the Huntsman Team SLVR (pronounced "Silver"). However, where there's a keyblade wielder there's bound to be Heartless and Nobodies [[spoiler: this time led by Braig aka Xigbar aka Luxu, who's apparently aligned with Salem.]] Needless to say, hijinks and action ensue... and Sora finds himself developing feelings for Ruby that make him question his feelings for his old flame...

* Recommended by @/CoreyGriffindor
* Crossover with: ''Manga/MyHeroAcademia''

* Pairings: Izuku Midoriya/Ochako Uraraka, Sora/Momo Yaoyorozu, Riku/Kyoka Jiro
* Synopsis: "There's no such thing as a quirkless hero" That is what people kept telling to Izuku Midoriya through all of his life. He understood it, even now that he was bestowed with All Might's quirk. However he kept wondering if it was possible if not here maybe somewhere else. He was about to find out when he enters UA academy and meet two interesting boys. Life's about to change forever.
* Comments: Takes place after the events of Kingdom Hearts III after Sora uses the Power of Waking to save Kairi, he is separated from his worldline and ends up in the MHA worldline with Riku deciding to use the Power of Waking as well to find Sora. A great fusion of both series while it does follow the MHA story it still has that Kingdom Hearts blend that works incredibly well. Story was published before the release of ''Kingdom Hearts III Re:Mind'' and ''Kingdom Hearts: Melody of Memory''.

* Synopsis: Xehanort may have set up a perfect house of cards, but Maleficent is intent on knocking it down. She's been irrelevant for far too long, and now, with a little help from some villainous friends, she's going to take back her crown.
* Comments: A thoroughly 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.
* Now has a [[Fanfic/QuiteAGlitteringAssemblage trope page]].

* ''Comments'': Aqua being a mother for Ruby and Yang offers a unique dynamic to the story. Not does Ruby and Yang have a mother figure, gives them unique and good character development. Aqua as a mother feels well balanced and fresh for the story.

* Set in Post-Kingdom Hearts Story and season 1 of Winx Club
* Comments: Story is interesting with fun adventures and action is good, some bit of spelling and slight grammer but appears to improve over time to correct mistakes. Balanced combination of two fictional universes and character development with the OC as the main character and interaction between characters. Also interesting lores which have not been focused and blend between different worlds.

* Recommended by: Tropers/{{Lermis}}
* Crossover with: ''Franchise/MassEffect''

* Synopsis: He didn't have anything when he was born. Just a name and number. But over time, what he had grew. He, with his friends began to understand that there was more to their existence then just their name and number. They will prove that they were meant to be real. To exist. To become something more than just a Nobody.
* 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 ''Franchise/TheIncredibles'', ''WesternAnimation/TreasurePlanet'', ''WesternAnimation/LiloAndStitch'', and more.

With the threat of the looming Waves of Darkness, and the judgment of people he's never even met, will he succeed in saving this world with only his shield?
* Comments: Sora, being Sora, not only manages to sway Aultcray for the better, his action of saving Motoyasu ends up with the two joining forces rather than forming a party, and allowed Ren to see how biased people are against the Shield Hero despite Sora's positive personality. meanwhile, Sora's friends are looking for him, while saving slaves along the way, including Raphtalia and Keel who mistake Goofy for the Shield Hero.

* Recommended by [=PhantoMaster=]
* Crossover with: ''WesternAnimation/TheOwlHouse''
* Status: Completed as of 9/17/2023. (First season finished) Season Two will be coming at some point in the future! Author is going on a hiatus for now.
* Synopsis: In the climactic finale of ''VideoGame/KingdomHeartsIII'', Sora uses the Power of Waking to set out on a deeply personal quest in search of Kairi. He embarks on a thrilling new expedition, awakening in the extraordinary realm of the Boiling Isles, where demons, magic, and witches abound. Unbeknownst to the Keyblade Wielder, Sora would forge new friendships, encounter both fresh and familiar foes, reunite with old comrades, and face daunting trials as he seeks his lost companion in the demon realm.
* Comments: Despite being written in a script format and having some spelling and grammar errors, as well as a few minor plot holes, this fanfiction crossover is captivating to read. The narrative presents thrilling adventures, engaging action/fight scenes, endearing chemistry or relationships among the main protagonists and the characters, and compelling drama. What sets this fanfic crossover apart is its commitment to the original worlds' lore, skillfully blending them as the story unfolds and expanding upon them to create a unique storytelling experience. Moreover, it delves into intriguing subjects that haven't been explored across the two series and seamlessly weaves them into the plot, adding to the story's allure.

Post-''Ragnarok'', Kratos has heard rumors of the Keyblade (namely the horror stories), and while distrustful at first, goes about helping Sora find his way home with help from others. As always, things never go as planned.
* Comment: Sora might feel a bit too casual when interacting with the other ''[=GoW=]'' characters, even taking his near constant optimism into consideration towards a particular world's rules or when explaining, but he does still have his moments of maturity to understand why certain actions were Bad Ideas (such as being told a few times his haste to do something tends to make things worse).
