Sora was an average teenage boy, though average was an understatement. At the age of fourteen, he was thrust into a battle between light and darkness, wielding a mystical weapon known as the Keyblade, saving worlds from creatures known as the Heartless and finding his friends, Riku and Kairi. He has saved the universe many times from the Heartless, saved Kingdom Hearts from being controlled by those with evil intentions, and has made new friends in each world he visited.
However, he fails his mark of mastery exam after almost getting himself killed by Xehanort's younger self, needing to be rescued by his friends as Riku and Kairi become Keyblade Masters. Needing more training before he can retake his exam, Master Yen Sid gives him coordinates to somewhere in the galaxy, though the information on what was there or why was unanswered, obeying his teacher. But as he was close to reaching the coordinates, his own gummi ship, which he crafted on his own while on a break a week prior to his exam's failure, malfunctions for some unknown reason and crashes into the world of Equestria.
With no way to make it back home, and Equestria too far from the rest of the worlds to contact his friends or fix his ship, Sora is stranded on this new world until someone realized he's been missing. Until then, he's going to have to fit in, his magic transforming his body into being a part of the world like in many others he visited in the past, and be patient. Little does he know that there were also dangers that lurked in this world, aside from any Heartless that may appear.
Sora's story takes place after the events of Dream Drop Distance, his adventures beginning in Equestria before the season 1 premiere of My Little Pony: Friendship is Magic.

EDIT: Those who are new to this story, there are links in a majority of the chapters where they lead to soundtracks of Kingdom Hearts to help build an atmosphere in the story. Sadly, most of them may come up as dead links because those videos had been taken down by the YouTuber for some reason, even if there are some still active by that same person, or they'll be gone as well if they happen again. With how many chapters I've put in this story, and how many links there might be, I don't have the patience to take them down or find new links with the right music I chose for those moments if I can remember which ones. So, up until Equestria Girls: Legend of Everfree (Part 3), ignore the links, as much as I hate to say that with the hard work I've done. Hopefully this crossover will be as enjoyable without music as it keeps on going. 
Interesting start. I can't wait to see how things continue to change with Sora involved.
7204965 Glad you're enjoying it so far.
The summary gave the impression that he landed on the wrong planet, but the start says that was where he was supposed to go.
Other than that this is pretty interesting, still is amazing that Sora somehow didn't spill the beans about him being from another world. He couldn't do that at all in the games, even when he tried to at Atlantica. Anyways, good start and I can't wait to see where this goes.
7205315 I think I see how confusing the description was to the first chapter, and I thought it was clear enough. Equestria was the coordinates, but his ship malfunctioned right as he got close to the world, crash landing in the world he was meant to go to.
Hopefully that sort of cleared it up a little. If not...
whoops,
Interesting.
At first I thought she had found the keychains instead of the Summons. Though I gotta know, does he have any of the keychains or is the Keyblade in default Kingdom Key mode?
The "Rainbow is a dumbass rusher" cliché is starting to be well cliché. It is unfortunate that this still works out even on the most recent canon episodes due to a lack of development...... I think. Haven't seen any of the new season or a bit of the last one.
Still other than that this was a pretty good chapter. Odd that he can change without his friends or any allies to be the medium but it is cool. Goddess I hope Rainbowdash gets some punishment next chapter. Having him arrested is whatever, but attacking him and basically forcing him to not be able to come quietly needs some punishment.
7208716 Sora's Keyblade is always in Kingdom Key default mode. And I always thought the chains were something that he could use at will, changing the style of the Keyblade from his heart or something...Not really established with how their transformation works...
And I believe in Dream Drop Distance, Sora always looked like he was in his Valor Form throughout the game. I haven't really played the game myself, cause of a lack of a 3DS, and I don't want to spoil myself watching a walkthrough. All I know is how it ends...sort of, and Young Xehanort.
One of the HARDEST optional boss fights in KH: Birth by Sleep Final Mix in the KH 2.5 Mix. 
Stupid time reversal!
As for Rainbow's rushing without much proof of the situation, I don't think it happened much in the last season, or in this one so far. I may need to read the synopsis' for the other seasons to see where she finally stops assuming everything and charges headfirst into a brick wall.
7209237
Sora's clothes in the Dream Drop Distance aren't in any form really they just changed again. They just got changed I guess because of being in a quasi-reality state, or that the makers of the game wanted a simpler outfit that is distinctive for telling which game a screen shot came from for the players. I don't fully get it myself because I am only on the third world in the game. Plus Xehanort has age flopped so many times in the series it is ridiculous. Plus keeping his Keyblade in default Kingdom Key was a good idea. Sora loses and gains forms for the Keyblade so many times between the games it is hard to keep track.
7209422 Huh...Well, I stand by the fact that he's in perma-Valor Form though. I mean, in the trailer for KH3, which should stop being delayed, he still wore his black clothing. That's just what I think though.
And UGH! WHY XEHANORT NO DIE!?
How many times can one person get killed, in so many different forms, before he finally kicks that overly kicked bucket!? 
7209999
Well getting killed twice makes sense. Once as a Heartless and once as a Nobody. Haven't finished Birth by Sleep so I don't know if he is killed. Still gotta agree on that. Hell I know of 3 if you count Rikku overcoming his transformation into Xehanort as killing him again.
7210507 Oh, you are gonna be shocked once you see the end of Birth by Sleep. If you have the Kingdom Hearts 2.5 Final Mix version, RUN AWAY! Don't play the hardest difficulty and go for 100% completion! It'll drive you insane!...Especially the mysterious figure...
So many attempts...so much suffering...so much annoying. 
Too late lol I'm almost done with it just need vanitas remnant and mysterious figure and then I'll be done
7210859 Good luck with those fights. A hint for Remnant Spirit Vanitas, no Cure spells...Just saying.
If the Keyblade being magnetic won't freak ponies out, Sora as a OFFENSIVE magic-wielding pegasus will. I wonder if offensive magic is illegal in Equestria...
There are some good Kingdom Hearts cross-overs and there are some bad Kingdom Hearts cross-overs... yours my dear author? It is pretty damn good. Can't wait to see the future chapters
P.S. ... ... ... I want ice cream. Gotta go buy something from the store! Bye bye!
Ill keep an eye on you for now
7212713 As long as that offensive magic is used for good and not evil, I'm not complaining.
7212724 Thank you very much, cloud of Z's that make it look like you are asleep but awake.
I wouldn't want to tarnish Kingdom Hearts's epicness...even though I have never played Dream Drop Distance. 
Darn money problems...
7212933 ...Where did you put the eye?
I-Is it flying around me right now and I can't see it!? 
Glad you like it...or do you?
7213067
I just wanna see where it goes for now. Love seeing a different take on Sora then my own version in KHoH
... Poor Sora, being a gentleman is not one of his best strengths. At least he got to made her smile
P.S. Welp, now comes the confrontation! My calculations tell me that there are gonna be two more chapters! One were they go to the castle and all shit happens in the way. The next one being the most anticipated fight of Sora vs Nightmare Moon!
P.S.S. ... ... Someone can recommend me something to eat and drink for the next chapter? Thank you!
P.S.S.S Bro, search for some groups and add your story to them. Would raise your views by 30%! That is a lot bru!
.... Bro! We meed a Bulk Biceps emoji!
7215940 We need a Discord emoji for anything involving chaotic randomness. And recommendations for food...Popcorn, hundreds of gallons of soda, and tons of chocolate...
7216197
... .... that... is an incredible idea!
P.S. Now comes the most expected act of the book!
P.S.S. Da fraq? It didn't told me that you gave a reply to my message... nor did I found the story today on the 'updates' board at the front page. Maybe I missed by one story... which would be weird cuse today I refreshed the page like... I dunno, a thousand times? Meh.
P.S.S.S. That was a fast update :D
7216640 Yeah, I kinda noticed my story didn't show up on the updated story list when I posted the last chapter...Maybe it got overtaken by several other stories being updated at the same time???
idk. I ain't that good a programmer to understand web stuffs...and I'm in school for IT.
And it took me almost the whole day to make that chapter aside from making at least two. And any insight on having the MLP songs involved and Sora taking part in the songs. It would be just like the Atlantis in KH2, except imagining him singing better than in those other songs...Well, Under the Sea was pretty damn good though.
7210667
I know that. Had to restart the game because I couldn't even handle the guys in Sleeping Beauty's castle on Proud. That was a blow to the ego.
cdn.meme.am/instances/500x/65003566.jpg
P.S. Welp, now comes the most tedious part of every mlp fiction just before season 1... the fillers.... Oh man.
P.S.S. Continue loving the story
P.S.S.S. 7217552 ... ... ... ... ... .... ... ... ... just wanted to add myself on the conversation :D
7217552 Well, practice makes perfect. It's possible, but you'll need a lot of time...and you may need to make a ton of Defense Ups in case you can't take the constant stun locks and curing yourself every five seconds.
If Sora is fourteen in this story, than how old are Riku and Kairi?
7219012 He's actually sixteen. If you read the description of the story, it takes place after Dream Drop Distance. Riku and Kairi are around the same age as Sora. I think they were fourteen since the start in KH, and now they're around sixteen after possibly months in the first game, a whole year after Chain of Memories, and some more months during KH2 and Dream Drop Distance. That's just what I think, though...At least I'm not going through all of the timeline. That'd be a pain.
7220325 I am one of those characters. Have you seen my horribly made avatar/OC?
But seriously, I kinda just go with the flow of things. And since Sora is able to blend in with the other worlds a bit better than most, it'd be hard to tell if he was from another world to the inhabitants of said world. Just as long as he doesn't blab about everything to ALL of the world...Or maybe I'm lucky.
how many seasons are you going to do?
7220886 I might do all of them, though I'll have to skip certain episodes in a season and move some of them up to the actual time of a holiday episode, like Winter-Wrap Up and Hearth's Warming. I will put in chapters involving some of Sora's conflicts, random hilarity, and if anyone else wants me to, the Equestria Girls movies. I will skip episodes I don't think were that important, or there won't be enough of a comedy routine for Sora to be involved in. If you don't like MLP retold stories, then that's fine if you don't like it.
7220956 Well, I did read the first few chapters of your story, and it was ok. Though I was a little confused with the extra characters from the dream realm part. If they were in Dream Drop Distance, then I have no clue what goes on in that game. And yes, I read the description, the story taking place after Kingdom Hearts 3, which needs to be out now, not later. It's good so far for your first story.
7221672 yeah can do the equestia girl movie as well and you can skip some of them or even mix the episode so they are in there proper weather season if that helps
I thought being a pegasus makes fighting Heartless easier to do. Did Sora just swear by Kingdom Hearts?
7221672 I would like it if you did the Equestria Girls movies.
7221776 Okie dokie lokie!
7222056 It should, but he was dealing with mage Heartless. Their spells can be a nuisance, especially the Green Requiems when they fully heal their Heartless allies. And don't get me started on the Crimson Jazzes from KH2. Those freaking fireballs are so annoying when they cast those tiny ones.
And yes. Yes he did swear by Kingdom Hearts.
7222777 well the winter wrap up wasnt a holliday epsidoe that be okay to post in order
7219012
Sora was 14 in the first game. The second game was he was 16 or was he 15? Either way the author I think stated in an early chapter that Sora was at least 16 years old. So if I remember the games right Kairi would be 16 too and Riku was a year older so he is 17.
7223437 It's an event that's done yearly, so technically, it kind of is a holiday.
Oh well. Opinions.
Wait a second, Sora had only met one prince The Beast. So Sora is hoping that Prince Blueblood is an aggressive, possessive jerk that does technically have a good heart buried in there. Though I guess Aladin might count prince.... though technically he is only dating and hasn't married Jasmine yet. So still Beast is still a step up from Blueblood. So hard not to type Blueballs instead of Blueblood.
7223489 true but the episode was about getting ready for spring with twilight trying to fit in in which group
How did they not see the fireballs launching from under Sora, Fire is not a very subtle spell. Still given the history with Riku it does seem odd that before having the talk with Rainbowdash that Sora would drive Gilda away like that. Then again he did get a bit more vindictive in later games.
7223498 That would have been hilarious if his name really was Blueballs. Too bad My Little Pony is a show for little girls, so that name can't be used...
Oh how cruel fate is to make fun of a character who was a huge jerk, and the characters can't mock his name in the show.
Also, Sora uttered the spell quietly, and it was the first level Fire spell. Of course no one would have seen the fire shoot out since it was a small spark just tiny enough to relight the candles. The Three Goofballs shall strike when no one expects it!
oh looks sobody got a crush on sora
A'wwwwww
so cute!
P.S. Yo gonna kill us all with cuteness!
P.S.S. Twilight's gonna end up smitten worse than... I don't know. Something? Meh.
P.S.S.S. From here it only gets worse
P.S.S.S.S. Her crush, not the story. The story only gets better.
P.S.S.S.S.S. Love the story.
P.S.S.S.S.S.S. I think I said that too many times?
P.S.S.S.S.S.S.S. Is it legal or even possible to have too many P.S.?
Oh man, I really hope that crush is either temporary, or that things work out ina way that doesn't leave Twi heartbroken. Sora is still stuck on Kairi...though, things might change, right?
7226111 sora like kairi yeah but he never said i love you to her maybe in kh3 i mean they just good freinds ther care about eath other right now
7226087 ...Uhhhh...invisible comments...That's a first
7226094 Unless you add a T. at the end, then it would only sound like a whisper
oh god the way this is set sora likes kiri, kiri likes sora, twilight likes sora, sora might reject twilight and twilight might become a heartless only to be saved by sora or riku might come along some where and steal her heart.... in the romantic sens not the darkness also am i rembering right can nobodys regrow hearts
wow what this chapter man this is great
i ship sora and twilight aka soralight
